Science Leadership on the International Scene
The DFO Science Management Board (SMB) was created in 2005 to set the strategic direction for DFO Science by identifying priorities and providing guidance on the alignment of resources. The SMB is chaired by the Deputy Minister and includes the Assistant Deputy Minister of each major client sector, two senior scientists, the Chairman of the Science Advisory Council and a Regional Director General from both the East and West Coast.
At its first meeting, the SMB established that its highest priorities are the adoption of an ecosystem-based approach to science and regenerating its workforce. Ecosystem science is consistent with international trends and is an important and necessary shift in the way DFO provides science advice and support.
Other priorities include science in support of sustainable aquaculture; navigation and sovereignty; Northern aquatic ecosystems; aquatic animal health and the Species at Risk Act; as well as issues of high importance to Canadians such as rebuilding cod stocks, Pacific salmon and seals.
Aquatic animal health is a science priority. A joint DFO Science/Habitat 2005 project recorded still and video images of bull trout spawning in Alberta's Sheep River. The handsome member of the char family is native to western Canada and the northwestern USA. In Alberta, changes to its habitat and over-fishing depleted the bull trout and in 1995 a catch-and-release program was instituted as a conservation measure. A decade of federal and provincial science and land management efforts plus public education about habitat, environmental and fishing regulations have assisted the Alberta bull trout to regenerate considerably.

Science Advisory Council
The Science Advisory Council (SAC) provides advice to DFO Science management on strategic matters pertaining to science and technology. Membership on the Council consists of about 15 individuals from outside the Department, and 4 ex-officio members from within DFO Science. The Council possesses a diverse range of expertise and experience in fisheries, oceans and freshwater science and technology, communications, and industry-related sectors such as fisheries, oil and gas, aquaculture, shipping, and other areas of interest to DFO. The SAC Chair is a member of the Department's Science Management Board and the federal Council of Science and Technology Advisors. This ensures a link between the different advisory functions, both within the department and government-wide. The Council has been engaged in the renewal of DFO Science since the review of science was initiated in May 2004. SAC has helped to provide an external perspective and insight into the considerations of our science partners and clients.
Centres of Expertise
In 2005, DFO Science expanded the creation of Centres of Expertise (COEs). These centres foster collaboration and partnerships between DFO and other government departments, other levels of government, and academia, industry and international colleagues.
There are two types of Science COEs – virtual and geographic. Virtual COEs bring together geographically dispersed expertise and infrastructure on a project-by-project basis. Geographical COEs combine people and infrastructure in a single research institute to support work in a specialized area.
Four COEs Are Fully Operational
The Centre for Offshore Oil, Gas and Energy Research (COOGER) is a virtual COE that coordinates research efforts into the environmental and oceanographic impacts of offshore petroleum exploration, production and transportation. COOGER is building on the existing expertise available at the Bedford Institute of Oceanography to address specialised issues in oil and gas research. COOGER is also focused on sharing expertise and resources in an international setting. Learn more at http://www.dfo-mpo.gc.ca/science/coe-cde/cooger-CRPGEE/index-eng.htm
To identify if there is an impact zone asociated with production water discharges from the Hibernia oil platform. The Centre for Offshore Oil, Gas and Energy Research (COOGER) conducted a research mission on the CCGS Hudson to sample the water column, benthic boundary layer and sediment surrounding the gravity base structure. The Hibernia oil filed is located 315 kilometres, east southeast of St. John's, Newfoundland and Labrador, in 80 metres of water.

The National Centre for Arctic Aquatic Research Excellence (N-CAARE) is a virtual network of experts that focus on increasing knowledge of Arctic marine and freshwater. The N-CAARE secretariat is at the Freshwater Institute in Winnipeg, Manitoba.
The Centre of Expertise on Marine Mammalogy (CEMAM) is a virtual COE that brings together marine mammal experts with a secretariat located at the Maurice Lamontagne Institute in Mont-Joli, Quebec. Researchers work on a wide range of projects to obtain information on the dynamics, ecology and health of marine mammals. See: http://www.dfo-mpo.gc.ca/science/coe-cde/cemam/index-eng.html
The Centre for Pesticides is a geographic COE located at the Freshwater Institute in Winnipeg. It coordinates the research of five federal departments in support of regulatory decisions of the Pest Management Regulatory Agency.
Six additional COEs Will Be Operational in 2007
The Centre for Ocean Model Development and Application (COMDA) is a virtual COE based out of the Bedford Institute of Oceanography in Dartmouth, Nova Scotia, that includes experts from Environment Canada and the Department of National Defence. The purpose is to develop operational, global, coupled atmosphere-ice-ocean assimilation and prediction capability for Canada using hindcast, nowcast and forecast models. COMDA will be part of a national Operational Oceanography system for Canada.
The Centre for Research on Hydropower Impact on Fish and Their Habitat integrates the expertise of DFO and the Canadian Electricity Association. This virtual COE based out of Mont Joli, Quebec will jointly establish the research priorities in both freshwater and marine environments and provide leadership in the area of cumulative impacts.
The Centre of Expertise on Aquatic Animal Health will be a virtual network of experts, hosted at Moncton, New Brunswick with satellite reference labs in Winnipeg, Manitoba, Nanaimo, B.C., and Charlottetown, P.E.I. that will provide the regulatory research necessary to support the federal regulatory program.
The Centre of Expertise for Aquatic Risk Assessment (CEARA) based in Burlington, Ontario, links to the Canadian Aquatic Invasive Species Network, which is funded by the Natural Sciences and Research Council of Canada, DFO, Transport Canada and other agencies. CEARA focuses on the principal pathways that transport aquatic invasive species to freshwater and marine ecosystems in Canada; characterizes the factors that influence establishment success of these species; and constructs risk assessment models that direct future management policies. CEARA develops national standards for conducting biological risk assessments for aquatic invasive species and coordinates and tracks risk assessments as they are developed.
Toxic Chemical Analysis centres are being established to undertake routine analytical services and to support research. Geographic COEs will be located at both the Institute of Ocean Sciences in Sidney, B.C., and the Maurice Lamontagne Institute in Mont-Joli, Quebec.
Aquaculture Centres of Expertise will be both geographic and virtual. Substantial infrastructure already exists at the St. Andrews Biological Station (SABS) in St. Andrews, New Brunswick and the Centre for Aquaculture Environmental Research at the University of British Columbia in Vancouver, B.C. This infrastructure will be linked to evolving research needs.
Targeted Research: Highlights

Pacific Killer Whale: Species at Risk
Pacific killer whales are protected under Canada's Species at Risk Act due to their small population size and recent declines in abundance. Threats to survival and recovery of these populations include environmental pollutants, physical and acoustic disturbance, and reductions in the availability or quality of salmonids, their primary prey. CEMAM researchers examined food limitation as a potential factor in decline, and reviewed 25 years of accumulated data to show that chinook salmon and, to a lesser degree, chum salmon, are important prey for resident killer whales, while other smaller salmonid species are not. Fluctuations in observed versus expected mortality rates showed a strong correlation with changes in chinook salmon abundance, but no relationship to chum salmon abundance. A sharp drop in coast-wide chinook abundance during the late 1990s was closely associated with a significant decline in resident whale survival. The whales likely prefer chinook due to its relatively large size, high lipid content and year-round presence in their range. Resident killer whales may be especially dependent on chinook during winter, when this species is the primary salmonid available in coastal waters, and the whales may be subject to nutritional stress leading to increased mortality if the quantity and/or quality of this prey resource declines. Chinook salmon is clearly of great importance to resident killer whales, but determining whether the species is the principal factor limiting whale productivity will require ongoing monitoring of both salmon and whale population trends.
Haida Eddies Studies Featured in Deep Sea Research
In April 2005, a special issue of Deep Sea Research focused on multidisciplinary research on Haida Eddies. These eddies act as feeding oases as they transport immense volumes of coastal waters and biota from Hecate Strait out into the open Gulf of Alaska. This publication contains eleven scientific papers contributed by DFO Science staff and international collaborators reporting on observations carried out from 1998 to 2003 under the DFO Strategic Science Fund. The research revealed that these eddies contain much of the biological activity in the Gulf of Alaska — everything from plankton to whales. The study also revealed that Haida Eddies transport water and biota to the proposed Bowie Seamount Marine Protected Area (MPA) lending new insights into the “connectedness” of the MPA to coastal ecosystems:
Tracking Cod Acoustically
DFO scientists studying Gulf of St. Lawrence cod stocks tracked fish using acoustic transmitters or pingers. The study confirmed that at least 60 percent of the Gulf cod population migrates farther out to sea in the winter, to the zone designated by the Northwest Atlantic Fisheries Organization as the 3Ps fishing area. These fish then move back to the Gulf in April. Two hundred and fifty-five codfish from the Gulf were implanted with acoustic transmitters and 80 receivers were arrayed in the waters off Port aux Basques, southeast of Burgeo and on the western side of St. Pierre Bank. While some receivers from farther out in the 3Ps area were unrecoverable, leaving as a mystery where the fish go once they are in 3Ps, the data collected raises questions about the abundance surveys carried out on the 3Ps stocks. One annual survey is done in April when Gulf cod may still be in the area, which could lead to an inflated estimate of cod abundance in the 3Ps area. This new scientific data adds to the information available for future decisions about when to schedule surveying, and about fishing quotas for both areas.

Dredging Impacts on Habitat
In response to a specific request from DFO Quebec Region, a multidisciplinary team of scientists made an extensive examination of the impacts of dredging and the deposit of dredged sediment on habitat in the waters of the mid-section of the St. Lawrence Estuary, near Isle Madame. The goal was to gain, for the first time, a thorough understanding of the benthic ecosystem in the estuary's transition zone where fresh and saline waters mix. The results of this study are applicable to the formation of policy recommendations concerning dredging operations and the deposit of sediments in the estuary transition zone. It also revealed important information about habitat that is essential to the Atlantic sturgeon, a species that is of concern for population managers in the Québec Ministry of Natural Resources and Wildlife. The groundbreaking study used novel methods including seabed mapping and computer models of the dispersal of sediments. The project involved DFO scientists, the Canadian Hydrographic Service and the Canadian Coast Guard, as well as scientific colleagues from Environment Canada, the Quebec Ministry of Natural Resources and Wildlife, the Quebec National Institute of Scientific Research, the University of Quebec at Montreal and the Institute of Marine Sciences. The research program will culminate with a review at a symposium on the Atlantic sturgeon species during the annual meeting of the American Fisheries Society.
Discovery Corridor – Understanding Continental Shelf and Deep-water Ecosystems
A discovery corridor is a swath of ocean bottom and the water column above it, encompassing a variety of ecologically inter-linked seascapes/habitats that may support a range of biodiversity and may support previously unknown species and processes. Corridors may cut across gradients of depth, productivity, human activity or any other ecologically relevant variables, and serve as focal points for collaborative scientific studies.
Location of the Discovery Corridor in the Gulf of Maine
A five-year research strategy established in 2003 (Three Oceans of Biodiversity http://www.marinebiodiversity.ca/en/reports.html), called for the establishment of such corridors, and one was established in the Gulf of Maine in 2004. It encompasses various biogeographic regions, habitats, and gradients (see map below). The Canada-United States boundary approximately bisects the Discovery Corridor, which has been endorsed as one of the foundation projects for the US-based Gulf of Maine Pilot Census of Marine Life. The information collected in the Discovery Corridor will allow scientists to synthesize data from benthic and pelagic realms towards a fuller appreciation of ecosystem functioning.
In June 2005, Dr. Ellen Kenchington, Director of the Centre for Marine Biodiversity, with Dr. Erica Head as Chief Scientist, both from DFO, led a successful mission to the corridor aboard the CCGS Hudson. All the specific scientific objectives were met: to collect hydrographic data at Atlantic Zone Monitoring Station 2; to conduct benthic habitat surveys and hydrographic and plankton sampling in Jordan Basin, Crowell Basin, and the Northeast Channel using specialized equipment; and to record sightings of migratory right whales and other cetaceans.
The mission used four types of sampling gear. Videograp and Campod, mounted underwater video and still camera systems developed by DFO at BIO, captured images of the seafloor, including this one of sea anemones. BIONESS, a multiple net sampling system, sampled zooplankton from the water column. A conductivity, temperature, and depth recorder was cast overboard to measure physical characteristics of the ocean. Photo Credit: Ellen Kenchington
ArcticNet and Contaminants Research
ArcticNet is a major multidisciplinary research program involving an extensive network of researchers under the co-ordination of Laval University. Senior DFO research scientists Dr. Robie Macdonald of the DFO Institute of Ocean Sciences in Sidney, B.C., and Dr. Gary Stern of the DFO Freshwater Institute in Winnipeg are project leaders on contaminants research under the aegis of ArcticNet. Dr. Stern is the project leader for ArcticNet Theme 3 sub-project 3.4, Carbon and Contaminant Cycling in the Coastal Environment, and co-leader with Dr. Macdonald of the Theme 1 sub-project 1.3, Contaminant and Cycling in the Coastal Environment. Their work is helping to test the effectiveness of international controls on contaminants such as PCBs*, DDT** and PBDEs*** and, within the context of other ongoing research, to understand the effects that climate variation may have on the contaminant levels and the health of fish and marine mammal stocks.

Experiment Reveals Hidden Genetic Divergence in Body Shape Between Atlantic Cod Populations
Most recent studies of genetic differences in fishes have focused on differences at the molecular genetic level. However, studies of differences at that level may not accurately reflect divergence in the fishes' adaptive quantitative-genetic traits. Unlike molecular genetic traits, quantitative traits are open to environmental influences. Thus, common-garden experiments, in which fish from different groups are reared in the same laboratory environments, are needed to disentangle genetic and environmental influences on quantitative traits (e.g., growth rate, body shape). A common-garden experiment using cod from four populations in the Northwest Atlantic was conducted by DFO in collaboration with researchers at Dalhousie and Memorial universities. This experiment revealed striking genetic differences in body shape between populations when reared in common laboratory environments, even though no differences were evident between populations in the wild. Genetic differences in body shape appear to have evolved between these populations in order to counteract contrasting environmental effects on shape in the wild. These results suggest that much of the genetic diversity in fish morphology may be hidden, with selection for the same optimal body shape resulting in genetic divergence between populations subject to contrasting environmental influences.
Researching Atlantic Salmon
Some of Canada's most highly prized salmon rivers are in DFO's Gulf Region. Here, DFO is focusing its salmon research activities on the fresh water phase of Salmo salar during the first years of life and the return to the river for the big salmon, after their "fattening-up" at sea. In order to do so, DFO's Diadromous Fish Section is using many research tools distributed on the salmon rivers of the region, from sampling nets to electronic tags. In the summer months, the scientific activities essentially consist of estimating the quantity of juvenile salmon in the rivers. This gives a good idea of the success of the reproduction that took place during past autumns and is also a good indicator of the general health of the species in the system. The sampling regime in place is also essential to monitor and study some of the species that may potentially be considered as species at risk, like the striped bass and shad.

Key Monitoring Successes
The Atlantic Zone Monitoring Program (AZMP) of DFO Science contributes to a sustained, systematic, and long-term observation system that provides basic oceanographic information, and value-added products and services concerning the actual status of the marine ecosystem on the Atlantic coast, in keeping with international standards.
AZMP Data are readily available via the Department's Marine Environmental Data Services (MEDS) internet portal, http://www.meds-sdmm.dfo-mpo.gc.ca/isdm-gdsi/azmp-pmza/index-eng.html
The AZMP program accomplished much in 2005 to broaden knowledge of the ecosystem. First, there was a major increase in biological and chemical sampling, leading to a greatly enhanced description and understanding of the ecosystem. Second, there was a strong, cooperative, coordinated and consistent effort among the Atlantic regions to provide a thorough assessment of environmental conditions across the Atlantic Zone. Third, there were continued efforts to identify and address specific issues of importance in the ecosystem. These issues included the invasion of the Gulf of St. Lawrence by the Pacific phytoplankton species Neodenticula seminae; the long-term plankton changes in the Scotian Shelf-southern Newfoundland Shelf region through the Continuous Plankton Recorder program; the relationship between year class success for haddock in southwest Nova Scotia and the timing of the spring phytoplankton bloom, and a major input into the eastern Scotian Shelf ecosystem review.
The AZMP also provides the foundation for Canadian contributions to the Global Ocean Observing System and related national and international ecosystem observation and monitoring networks.
DFO Researchers Detect Flat Oyster Parasite in British Columbia waters
The protistan parasite Bonamia ostreae (the cause of an oyster disease of concern listed by the World Organisation for Animal Health – OIE) was found for the first time in flat oysters (Ostrea edulis) cultured in B.C. in 2005. Prior to this detection, this parasite was known to occur on both coasts of the United States and caused significant oyster mortalities in Europe. Entry into B.C. is thought to be via flat oyster seed imported from enzootic areas in Washington State. Although flat oyster mortalities were associated with the parasite at one location in B.C., the flat oyster industry is small (< 0.5 percent of all oysters marketed by B.C. producers) and the main culture species, the Pacific oyster (Crassostrea gigas), and the native oyster (Ostrea concaphila) are resistant to infection. To date, this parasite has not been detected in oysters from Atlantic Canada.
Toxic Algae Monitoring Program
Paralytic shellfish poisoning (PSP) and amnesic shellfish poisoning (ASP) are the most dangerous and widely distributed toxins in Canadian waters. In the Gulf of St. Lawrence system, PSP and ASP poisoning events are respectively related to the blooms of the dinoflagellate Alexandrium tamarense and the diatom Pseudo-nitzschia seriata. These algae can kill fish, contaminate shellfish with toxins, force harvesting closure at great economic and social cost, and in the worst case, harm human health. The frequency and geographic extent of these toxic algal blooms are increasing worldwide for reasons that are still not clearly understood. Potential causes are increased nutrient enrichment of coastal waters by human activities. The Estuary and Gulf of St. Lawrence is a region recognized as a hot spot for toxic algae, which is why researchers from the DFO Maurice Lamontagne Institute have monitored and studied toxic algal blooms since 1989. This program collects toxic and harmful algal species at 11 monitoring stations around the Gulf, which allows for the acquisition of new knowledge on the dynamics of these algae, and on the environmental conditions that favour their growth. The development of new observation technologies for the rapid detection of toxic algae and of models to allow prediction of algal toxic events are also important activities pursued by DFO scientists.

The Hypoxia Problem: Low Oxygen Levels Observed in Marine Coastal Waters
Understanding the impact of hypoxia on Canadian waters in the Gulf of St. Lawrence was a focus of researchers at the Maurice Lamontagne Institute in Mont Joli, Quebec, while researchers at the Institute of Ocean Sciences (IOS) in Sidney, British Columbia, tracked decreasing oxygen trends related to changes in upper ocean ventilation in the northeastern Pacific Ocean.
Studies of the St. Lawrence estuary during 2005 contributed to accumulating evidence that low oxygen (hypoxic) conditions are proliferating in marine coastal environments worldwide, with major ecological and biogeochemical consequences. Hypoxia in coastal areas can be caused by three major phenomena:
- increases in land-source input of organic matter and nutrients,
- changes in coastal wind regimes, and,
- formation and intrusion of open-ocean oxygen-depleted waters in near-coastal areas, through changes in coastal circulation.
In the bottom waters of the Lower St. Lawrence Estuary, a combination of factors (1) and (3) has caused a decrease in oxygen concentration. The major causes are a progressively decreasing proportion of oxygen-rich Labrador Current Water in the water mass entering the Gulf of St. Lawrence from the Northwest Atlantic, compounded by manmade stresses affecting the local organic carbon budget. Ecological impacts range from large-scale animal mortality to variations in species distribution, changes in biodiversity, physiological stress and other sub-lethal effects, such as reduced growth and reproduction.
On the Pacific coast, researchers at IOS investigated a 20 oxygen time series at Ocean Station Papa, which reveals a decreasing trend that appears related to changes in upper ocean ventilation. Ocean Station Papa, also known as Station P, is in the Gulf of Alaska at 50°N and 145°W. Lower oxygen levels in the open ocean may, in turn, bring some coastal and shelf ecosystems that once were just above the critical threshold defining hypoxia below this threshold, thus contributing to an increased frequency and prevalence of hypoxia worldwide. The decreasing oxygen trend at Ocean Station Papa represents a potentially important ecological threat for benthic and demersal animals on the upper continental slope off Vancouver Island.
Oxygen sensors deployed in 2004 on four Canadian Argo floats continue to help DFO monitor oxygen conditions in the northeast Pacific and in the northwest Atlantic in real-time. In 2006, DFO will deploy six new Argo floats with oxygen sensors in the northeast Pacific, and five in the northwest Atlantic, in an effort to better monitor changes in upper ocean ventilation and in the functioning of the oceanic carbon pump.
Ocean Data Profiles from Argo Float Program
Thirty countries deploy free-floating Argo buoys to profile oceanographic measurements at different depths. By the end of 2005, there were 2,400 floats in operation. They produce 87,000 ocean data profiles per year for use by climate researchers, for use in climate and weather forecasting, in fishery planning and other applications, http://www.meds-sdmm.dfo-mpo.gc.ca/isdm-gdsi/argo/index-eng.html
Oceanographic Buoys and Satellite Imagery
With funding assistance from the Canadian Space Agency, DFO researchers completed the installation of five oceanographic buoys powered by solar-panels in the Estuary and Gulf of the St. Lawrence to collect meteorological and oceanographic data including chlorophyll, surface water temperature, salinity, surface winds and surface humidity. The primary purpose of these data is to validate other types of information obtained from satellite remote sensing. The data are transmitted in near real time to the Maurice Lamontagne Institute and become immediately available on a web page of the St. Lawrence Observatory portal (http://slgo.ca/en/buoys/context.html).

Hudson's Bay Complex – Gigantic in Area and Sensitive in Nature
Another sensitive area under monitoring scrutiny in 2005 was the Hudson Bay Complex. The area comprising Hudson Bay, Hudson Strait, Foxe Basin and Ungava Bay is one of the continent's largest drainage basins, a significant contributor to the Labrador Current, and a major oceanographic feature influencing the hydrography and biological productivity of the northeast Atlantic shelves of Canada and the U.S. Approximately half of the Inuit populations of Nunavut and Nunavik live in the area and use it for hunting and fishing, for transportation of supplies and goods during the ice-free season, and for fostering economic development. The region's high biodiversity reflects the significant influence of both Arctic and Atlantic waters.
DFO Quebec region initiated an Observing/Modelling program, aimed at a minimal description of the current state of this region, as part of the MERICA program (études des MERs Intérieures du CAnada – MERICA) with sampling missions in 2003, 2004 and 2005. This monitoring program involved scientists from various DFO regions (Quebec, Central and Arctic, and Maritimes), a number of Quebec Universities (l'Institut des sciences de la mer de l'Université du Québec à Trois-Rivières, l'Université du Québec à Montréal, and Laval) and various other organizations (Woods Hole Oceanographic Institute, Québec-Oceans), and was conducted using ship time provided by the Canadian Coast Guard on an opportunistic basis. The MERICA program also integrated the northern component of the DFO Quebec region Species at Risk Act program, and represented an important component of the DFO N-CAARE (National Centre for Arctic Aquatic Research Excellence) program. Key oceanographic and living resource data sampled included variables such as temperature, salinity, current, nutrients, oxygen, the abundance and biodiversity of living organisms, contaminants, and more. The long-term objective of the program is to establish an integrated observation and modelling system for detecting, following and predicting ocean and ecosystem changes in the Hudson Bay Complex. Data accumulation under the MERICA sampling station program focused on answering key questions related to the impact of climate change on the carbon production cycle and the evolution of biodiversity in the Hudson Bay Complex under a general climate warming scenario.

ArcticNet – Community-based Monitoring
This major multidisciplinary northern research program involving a large network of researchers has many facets involving DFO. In one monitoring aspect of the program, DFO is collaborating with the University of Manitoba and northern residents on a community-based monitoring (CBM) program on sea-ice climate variability and change. It includes participation by the Northern Ecosystem Initiative, the Aurora Research Institute, and communities including Tuktoyaktuk, Sachs Harbour, Paulatuk, Holman Island and Sanikiluak. Surface meteorology stations established on first-year sea-ice were placed close to the communities. These telemeter data to the local Hunters and Trappers Committee (HTC) offices or area schools for data archiving. Every two weeks, HTC members visit the stations and collect snow and sea ice samples, and take photos. The information is transmitted to the University of Manitoba where it is put up on a website dedicated to the CBM program. To learn more about ArcticNet, visit the ArcticNet website: http://www.arcticnet.ulaval.ca
Identifying and Mapping Bottom Fish Assemblages in Davis Strait and Baffin Bay
To study abundance and gain new data on fish assemblages, DFO worked on a jointly funded research project with a variety of Nunavut partners. The Greenland Institute of Natural Resources research vessel Paamiut was used to study fish assemblages in Davis Strait and southern Baffin Bay, a relatively isolated body of deep polar water, unique among the Arctic seas. Using the Paamiut enabled researchers to compare results across the whole stock area as the same ship was used to assess Canadian and Greenland waters. DFO hopes to continue such multi-species surveys to acquire long-term data that is required to track fish population trends.
Water Level Fluctuations: Balancing Ecological and Energy Needs
A team composed of scientists and engineers from DFO, the Ontario Ministry of Natural Resources and Brookfield Power Corporation Ltd. are collaborating on a long-term Adaptive Environmental Assessment and Management experiment to test whether regulating the rate of change of water flow (known as ramping rates) through hydro dam turbines can provide a more favourable environment for fish, while allowing energy production to be maximized. The Before-After-Control-Impact Pair design is being utilized to provide the most reliable scientific results in this ecosystem-level experiment. The site is near Wawa, Ontario, on the 40 kilometre stretch of the Magpie River between Steephill Falls and Magpie Falls generating stations. The reference river is the unregulated Batchawana River, approximately 60 kilometres north of Sault Ste. Marie, Ontario. The before stage of the study is complete. Key components of the study are: physical habitat parameters, fluvial geomorphology, fish community characteristics, fish forage base and invertebrate drift, brook trout behaviour, food web dynamics, and an economic analysis of the cost of ramping at facilities in Ontario. Once baseline conditions were established on both rivers, ramping restrictions were removed. Monitoring during the ‘after', or experimental phase, will continue through 2007. If an effect is detected, restrictions on ramping may be incrementally reinstated in an attempt to balance ecological and energy needs during the evaluation phase. Results will be incorporated into provincial and federal waterpower guidelines and policy, facilitating science-based decisions regarding ramping at hydroelectric facilities. Methodologies developed will be incorporated into effectiveness monitoring programs for Water Management Plans at existing and newly developed hydroelectric generation facilities in Ontario.
Counting Pacific Salmon with Sonar
A DIDSON imaging sonar system was successfully deployed between August and October 2005 to estimate the escapement of sockeye salmon (Oncorhynchus nerka) in the Horsefly River, part of the Quesnel Lake system in the Fraser River watershed, in B.C. The Horsefly River was chosen for the first deployment because 2005 was a dominant year in the cycle of this stock and because a mark and recapture program was also conducted, facilitating comparisons between these methods of escapement estimation. Based on analysis of visual counts versus DIDSON counts, it was concluded that the DIDSON escapement numbers were not biased by undetected fish and are as accurate as visual counts. The DIDSON system will enable stock assessment staff to monitor spawning escapement 24 hours per day throughout the entire spawning run in turbid/clear and light/dark viewing conditions. With two to three staff reviewing files, daily escapement estimates can be provided one day after recording. The 2005 program illustrates a highly successful approach towards technology transfer from evaluation and testing of new methodologies and equipment to operational status through interdepartmental training of staff. The DIDSON system provides a practical and cost-effective approach for estimating sockeye salmon escapement in some terminal areas within the Fraser River watershed.

Biotechnology and Genomics
DFO scientists are generating information and applying biotechnology tools and techniques for the development of management tools and science advice, including: precise and rapid stock identification for real-time fisheries management decisions; sensitive tools for the detection and development of treatment/mitigation approaches for aquatic animal diseases; precise identification of populations of management concern, including species at risk; tools to meet biodiversity goals; metagenomics analysis with application in bioremediation (the use of microorganisms to degrade toxic chemicals in the aquatic environment) and understanding ecosystem components; identification and monitoring of physiological responses to environmental changes; and, research to support the development and implementation of regulations for aquatic animals with novel traits. DFO Science's Aquatic Biotechnology and Genomics Research and Development Program has identified four strategic research themes where the application of innovative and enabling technologies can be integrated in order to provide enhanced precision, sensitivity, and timely information for the provision of scientific advice and management tools. The four interrelated strategic research themes are: Biotechnology and Aquatic Resource Profiling; Biotechnology and Aquatic Animal Health; Biotechnology and Aquatic Ecosystem Health; and, Regulatory Science for Aquatic Animals with Novel Traits.
Science Advisory Process and Publications
The Canadian Science Advisory Secretariat (CSAS) coordinates the DFO Science Advisory process in collaboration with the regional Centres for Science Advice. This coordination network is responsible for maintaining high standards of excellence in the provision of peer-reviewed scientific information and advice in support of sound decision-making. During the last year, more than 70 advisory meetings (peer reviews and workshops) were conducted and more than 200 scientific publications (Science Advisory reports, Research Documents and Proceedings) were produced. These covered standard stock assessment issues but they also addressed an increasing number of emerging issues, such as ecosystem assessments, species at risk, invasive species, aquaculture impacts, and others. During 2005, several particularly notable advisory reports were released through CSAS, including reports on cod, snow crab and other species of particular interest, and framework reports dealing with species at risk and ecosystem overviews. CSAS publications and research documents, and the CSAS calendar of activities, can be found at: http://www.dfo-mpo.gc.ca/csas/Csas/Home-Accueil_e.htm.
Science in Support of the Species at Risk Act
DFO Science participated in 14 science peer-review activities involving over 70 species in 2005. DFO information holdings on priority species are peer-reviewed prior to their assessment by the Committee on the Status of Endangered Wildlife in Canada (COSEWIC). Seven species were subject to this type of review in 2005, including the American eel and several Pacific rockfish species. COSEWIC species status reports are also peer-reviewed. Over 40 such status reports were reviewed by regional scientists in 2005.
A key aspect of science advice in support of the Species at Risk Act (SARA) involves assessment of the recovery potential for species that have been assessed by COSEWIC, and for which listing under SARA is being considered.
Thirty species were subject to this type of review. The majority of these were freshwater species, but also included were some marine species including winter skate, striped bass (diadromous), and the beluga whale.
DFO Science also undertakes workshops that further develop scientific tools and techniques that assist the Department with implementing SARA. There were two such workshops in 2005: one for developing a framework for assessing allowable harm to freshwater species and issuing habitat authorizations under SARA; and a second to determine the characteristics of a recovered population in order to develop recovery targets and objectives for listed species.

Atlantic Seal Population Increases
During 2005, CEMAM researchers participated in the $6 million Atlantic Seal Research Program (ASRP), which examined seal abundance, distribution and diet. The harp seal is the most abundant pinniped in the North Atlantic and is harvested commercially. The last review of its population abundance indicated that the population has likely stabilized and currently numbers around 5.8 million animals, its highest level since the 1970s. The grey seal population had increased to about 250,000 animals in 2005. Advice on allowable harvest levels provided to fisheries management allowed opening of the first commercial harvest for this species. A survey of hooded seal pup production was carried out and the data are being analyzed, with peer review scheduled in 2006. The grey and harp seal assessments were peer reviewed in May 2005 and the results are in the CSAS publication series. Distribution of the three species is being determined using satellite telemetry. This component continues — both in terms of analysis of the data collected under the ASRP and the collection of additional data under the International Governance Program (and a proposal to International Polar Year, 2007-2008). Data on grey seals have been published in scientific literature and data on all three species have been presented to a number of scientific and public meetings.
The ASRP is improving our understanding of the potential role that harp, hooded and grey seals may be having on cod. The diet component of the ASRP consisted of exploring the use of fatty acids to determine diets and to improve sampling of harp and hooded seals in offshore areas (a major data gap identified in the cod assessments). Our ability to determine diets from fatty acid signatures has been shown and the model used to quantify the diet using fatty acids has been published in the scientific peer review literature.
Another component of the ASRP was a pilot study to determine the feasibility of seal exclusion zones. Preliminary results of this study were presented during an international workshop on Seal Exclusion zones. The report of this meeting is available on the CSAS website: http://www.dfo-mpo.gc.ca/csas/Csas/Home-Accueil_e.htm
Science Advice Leads to Turbot Quota Increases for Nunavut
Research conducted in 2005 by DFO and funded in partnership with the Government of Nunavut, Nunavut Wildlife Management Board, Nunavut Tunngavik Incorporated, Indian and Northern Affairs Canada, Baffin Fisheries Coalition and DFO resulted in an increase to the turbot quota for Nunavut. The research work resulted in the Northwest Atlantic Fisheries Organization (NAFO) Scientific Council recommendation of a quota increase of 5,000 metric tons in NAFO fishing zones 0A + 1A in 2006, resulting in a total turbot quota of 13,000 metric tons. Greenland and Canada have a 50 percent sharing arrangement, which will result in Nunavut getting half of the quota or 6,500 metric tons. This will increase Nunavut's share of turbot quota from 60 percent to 68 percent and increase Nunavut's overall offshore fisheries quota for turbot and shrimp, from 38 percent to 41 percent. Nunavut received the entire increase of 2,500 metric tons of the 2006 Canadian turbot quota in zone 0A located in northern Baffin Bay. The science-based advice was welcomed in Nunavut as it promises job creation and increased economic development.
Analysis Shows Eastern Arctic Bowhead Whales Form a Single Population
CEMAM researchers reviewed bowhead whale stocks in the Eastern Arctic during the year. There is a very limited subsistence harvest of these whales, whose numbers were depleted by commercial whaling that ended in the early 1900s. Eastern Arctic bowhead whales had been considered to form two populations, a Hudson Bay/Foxe Basin stock and a Davis Strait/Baffin Bay stock, based on inferences from commercial whaling records and physical land and ice barriers. Recent genetic work and monitoring of bowhead movements using satellite telemetry do not confirm the two population hypothesis, and instead, the advice is that Eastern Arctic bowhead could be considered as a single stock. Aerial surveys of this stock suggest a minimum abundance of around 7,000 animals.
Near Kekerton Islan, NU in the summer of 2006, two bowhead whales surface near a small freighter canoe piloted by Levis Quanaq of Igloolik. Biologist Larry Dueck stands on teh bow to attach a satellite monitoring tag to a bowhead's back. The project involved placing eight satellite tags and collecting 32 DNA samples from bowheads, which are Canada's largest Arctic marine mammals. Photo Credit: DFO
Traditional Ecological Knowledge about Belugas Compared with Satellite Telemetry
During 2005, CEMAM researchers made a comparison of eastern Hudson Bay beluga movements and aggregation patterns using satellite telemetry and Nunavik Traditional Ecological Knowledge (TEK). TEK consists of the collective ecological knowledge, experience and values of subsistence communities. Both approaches provide important ecological information but few studies have attempted to compare the two knowledge sources. The study revealed that both data sets can provide complementary information and that they both also suffer from weaknesses caused by limitations in data collection – weaknesses that need to be recognized when such data is applied to advice regarding resource management issues.
Oil and Gas Program - Northern Research
Throughout 2005, DFO conducted research to provide science-based advice and decision making in support of its regulatory responsibilities regarding the protection of fish and fish habitat with respect to the proposed Mackenzie Gas Pipeline (MGP) development. The MGP has the potential to have environmental impacts on the Canadian North due to pipeline construction, and related oil and gas activities. DFO reviews, and provides recommendations on the Environmental Impact Statement and conducts scientific research in order to ensure adequate monitoring and assessment of potential negative environmental impacts of induced oil and gas activities. DFO scientists are conducting onshore and offshore studies, and research to address information gaps identified during community workshops. Studies are being conducted on marine and anadromous fish species, seasonal use of the Beaufort Sea, and important migration routes. Beluga tagging studies are determining seasonal use of the Beaufort Sea and annual migration routes. Late winter and early spring seal studies are examining the potential impacts of offshore oil and gas activities on the abundance, denning and pupping behaviour, and annual migration of Beaufort seals. DFO scientists are also participating in the multi-agency Beaufort Sea Coastal habitat mapping program, which is examining all aspects of the marine ecosystem to identify areas that may require added precaution or avoidance during the planning of future offshore oil and gas development. This extensive set of Northern research programs are described at length on the Department's website.
Agricultural Drains Act as Fish Habitat
DFO's Fish Habitat Management sector requested advice on whether agricultural drains could be considered fish habitat. DFO scientists contributed guidance to a University of Guelph research study conducted to determine if there were differences in fish diversity, abundance, life stages and habitat between 25 warm-water agricultural drains in southwestern Ontario and 25 paired water courses not subject to drain maintenance. The study found no significant differences in any of the variables measured and concluded that agricultural drains do act as fish habitat. Habitat and drain managers will use the findings to develop drain management guidelines that consider the needs of agriculture, while preserving fish diversity and habitat.

Sizing up the Growth of the American Lobster
The American lobster has supported a commercial fishery since the middle of the 19th century. Landings were at, or near, historic highs during the 1990s and into the early 2000s, following a steep and unforeseen increase through the 1980s. In 2005, scientists from the Quebec Region published a study on the growth of juvenile American lobster off the Magdalen Islands. In addition to scuba sampling of lobster during two periods (1995-2001 and 2003-2004), the study critically reviewed current concepts about lobster early growth, emphasizing the scarcity of fine-resolution studies of growth of early benthic stages of the animals. The work contributes to the understanding of the variability of size-at-age and age at recruitment, which is a first step towards understanding the settler-to-recruit relationships – knowledge that assists effective management of the fishery.
Sea Scallop Fishery — Nova Scotia Benthic Mapping Project
The sea scallop fishery in southwest Nova Scotia, located in scallop fishing area 29, is unique in a number of ways. This new fishery has had full monitoring in terms of annual surveys, observer coverage, catch sampling and satellite monitoring systems since it began in 2001. In 2002, DFO entered into a three-year joint project agreement with the fishing fleets and Natural Resources Canada and all parties provided funds to conduct multibeam sonar acoustic mapping of the seafloor and associated scientific work. Access to fishing in the area was conditional on contributing to funding the project.
Maps of high-resolution bathymetry, acoustic backscatter strength and surficial geology have been produced from this project. In addition, benthic data were collected using photographic and video equipment for the analysis of the distribution of benthic assemblages in relation to bottom type. Video and data from the observer program show sea scallops were found in most areas but were most abundant on flat gravel lag and stable sands. Restricting dragging for scallops on the flat gravel lag or in sand could improve catches, minimize gear losses and greatly reduce bycatch and damage to species that live on or near the bottom of the ocean which are the most abundant on bedrock outcrops and till. The bathymetry maps were used in the last three years for planning survey tows, and as a result, greatly reduced gear damage during the annual survey. The 2005 survey was redesigned using surficial maps and preliminary results indicated that this new design resulted in more precise estimates of biomass. Finally, the commercial catch per unit effort was analysed using the surficial geology maps and the results suggested that current catch rates are being maintained by moving to previously unfished areas. The results of the 2005 survey were presented and reviewed with the stakeholders at a workshop early in 2006.
Scotian Shelf Fish Habitat Project Reveals Information about Haddock
A collaborative research program between the DFO Maritimes and Newfoundland and Labrador Regions that began in 2001, investigated how ocean bottom habitat space is used by deep water fish occupying habitat at the bottom of the Scotian Shelf. The focus was to determine the preferred habitat for juvenile haddock. This information is needed to manage both fisheries and habitat within an ecological context. In 2005 the ambitious field program concluded successfully. It was carried out at six 10 x 10 kilometre study sites, originally selected using historical DFO trawl survey data to determine high and low probability preferred areas. A cruise on the CFAV Quest collected high resolution multibeam data at three of the study sites. Seabed features down to 0.5 m could be resolved. The CCGS Needler conducted trawl surveys at all six study sites which will provide further information on the composition of fish communities and major benthic prey. The CCGS Hudson carried out extensive benthic habitat and community surveys at all study sites using a wide variety of equipment including sidescan sonar, Biosonics DT acoustics, Towcam (a towed video platform) and Videograb. This equipment will provide information on seabed structures, sediment composition, fish distribution in relation to habitat, and the composition of benthic communities. The large number of physical and biological data sets collected systematically at the same study sites is a unique aspect of this DFO project. Data analysis is now under way and the integrated results will be presented at a workshop in March 2007.
A Banner Year in 2005 for Maritimes Regional Advisory Process
During 2005, eleven Regional Advisory Process (RAP) meetings were held in the Maritimes to address issues from the stock assessment of eastern Scotian Shelf snow crab to the review of ecological overviews of the Bras d'Or Lakes. Consistent with the trend observed over the last number of years, RAP is increasingly being used to review Oceans, Habitat and Species at Risk issues in addition to those of fisheries stock assessment. An important RAP meeting in 2005 saw the establishment of an approach to the classification of benthic communities on the Scotian Shelf, based on their sensitivity to human impacts. This classification approach will be used by DFO Oceans in its efforts to manage the full range of human activities (from fishing to oil and gas exploration) impacting the bottom communities. Regarding the Species at Risk Act, the RAP meetings to review the recovery potential of porbeagle shark and winter skate were highlights for 2005. These reviews represent the most in-depth analyses of these populations conducted to date and will be important to the recovery plans of these species. Regarding fisheries assessment, the review of the Georges Bank yellowtail assessment model was another highlight. It was one of the most thorough investigations of a stock assessment conducted thus far. It uncovered issues with the assessment that will lead to improvements in scientific advice on this resource in the long term. Overall, 2005 was a banner year for RAP in the region.
35 New Rockfish Conservation Areas for British Columbia
Consultations with the commercial industry, recreational, and Aboriginal fishing sectors, local and provincial governments, as well as coastal communities and the general public have been conducted since 2002 to develop the network of Rockfish Conservation Areas (RCAs) in B.C. After these extensive consultations, 35 RCAs were implemented during the 2005 fishing season. Spatial analyses using fishery catch and bathymetry data were conducted to identify areas coastwide that could be considered “rockfish habitat.” This rockfish habitat layer was then used as a basis for selecting RCA candidate sites and to measure the closed habitat area targets. The 35 RCAs meet DFO's target of 20 percent closed rockfish habitat for the coastwide offshore area outside of the Strait of Georgia. Further consultations on new RCA candidate sites proposed for the inside of the Strait of Georgia began in 2005. Implementation of these new areas in 2006 will result in a total of 120 RCAs and will meet the target of 30 percent closed rockfish habitat for inside the Strait of Georgia. The 35 new RCAs implemented in 2005 for the coastwide area outside of the Strait of Georgia are closed to all trawl and hook-and-line fishing for the recreational and commercial fishing sectors.

Salmon Egg Research Provides Practical Data
The British Columbia Atlantic salmon farming industry depends almost entirely for its egg source on brood fish reared in British Columbian waters. Hence, collaborative research with DFO and the salmon farming industry was conducted, starting in 2003 to the present, on numerous factors affecting egg to fry development and survival (i.e., gamete handling, storage, fertilization procedures, and incubation temperature), as well as factors that influence the latter part of maturation prior to spawning (i.e., dissolved oxygen and temperature). The research yielded useful practical fish culture information for the salmon farming industry and data for the scientific community.

Management of Data and Information
The Marine Environmental Data Service (MEDS) is DFO's oceanographic data management and archive centre. MEDS acquires data collected by researchers from Canada and abroad, converts them to common data structures, ensures they are of a consistent quality and provides these data to others. MEDS is a member of an international consortium of data centres, some of which manage data in real-time and coordinate their efforts through the Joint Commission on Oceanography and Marine Meteorology (JCOMM). Others manage delayed mode data through the Intergovernmental Oceanographic Data and information Exchange (IODE). MEDS is a strong player in both JCOMM and IODE, a position that is unique in the world.
During 2005, as it has for many years, MEDS managed many different sorts of Canadian data, such as readings from tide gauges, ocean temperature and salinity readings from Argo floats, and many other ocean environmental variables, as well as data acquired through acoustic tracking of fish, data on invasive species distributions and much, much more.
Modern oceanographic research such as that undertaken by MEDS requires international linkages and the co-operation of many partners to be both affordable and increasingly effective. A large percentage of data contributed to MEDS comes from international sources. For some data, MEDS acts as a global data centre while for other kinds it only acquires data from waters around Canada. For certain data, MEDS distributes all that it receives to researchers at data centres in six other countries, and, in effect, issues the contents of its archives six times annually.
For several years, MEDS has supplied access to real- time data to the Global Ocean Data Assimilation Experiment (GODAE), an initiative to learn how to build and operate coupled ocean-atmosphere-ice models. Through links forged in IODE, MEDS entered into an agreement to supply French modellers contributing to GODAE with real-time data. In 2005, Canadian researchers also began a modelling effort and settled on using the French model. As part of a close working relationship with the data centre in France, Canada acquired a copy of the French-developed software used to prepare the data for assimilation into the model. MEDS continues to supply data to France and is also building the necessary software to provide the data to Canadian modellers.
Also during 2005, MEDS started a pilot project with the DFO Institute of Ocean Sciences to attach a "bar code" to the data collected at each ocean location. This is attached at the creation of the data and follows along whenever the data is moved. The bar code addresses the need to identify data that may be received multiple times by the DFO data system.
One of the key issues with respect to data is the lack of standardization among national and international data types and the challenges that presents to interoperability. DFO undertook a national workshop in 2005 to address the topic of “Service-oriented Architecture” (SOA) which seeks to harmonize standards. The outcome was a national commitment to the need for SOA, and the recognition that SOA is required for DFO Science Sector to achieve maximum use of its data archives, and in turn, to service Canadians, and its international commitments effectively.
Data, Products and Services
Canadian Hydrographic Service
The Canadian Hydrographic Service (CHS) is the division of DFO Science responsible for surveying and charting Canadian waterways for safe and efficient navigation. During 2005-06, the CHS distribution offices distributed 153,779 charts and 92,637 publications through the 800 authorized dealers across Canada and USA. CHS produced 129 New Editions and New Charts in paper and 106 new Electronic Navigational Charts in S57 format including 85 New Editions. Fifty-two raster navigational charts were released including six New Charts. There were over one million visitor sessions on the Tidal web site requiring tidal information, and over 3,500 calls received at the toll-free number for water levels and tidal information during 2005. For more about the CHS and its many products, go to its online portal, at http://www.charts.gc.ca/
Atlantic Zone Monitoring Program Indices and Bulletins
In addition to the CHS, other branches of DFO Science are also directly responsible for the production of numerous data outputs, products and services which are used daily by Canadians and international users involved in transportation and industry as well as recreation. For example, the annual Atlantic Zone Monitoring Program (AZMP) provides direct access to a compendium of oceanographic data, climate indices, plankton data, sea level data, remote sensing data and meteorological data. All of this information is publicly available from the MEDS section of the department's website http://www.meds-sdmm.dfo-mpo.gc.ca/isdm-gdsi/azmp-pmza/index-eng.html
Online Delivery of Oceanographic Data
With the help of a university partner (ISMER-Institut des sciences de la mer de Rimouski) DFO completed the first phase of an oceanographic buoy network in the St. Lawrence during 2005. Available in near real-time through a website (http://slgo.ca/en/remotesensing/data.html). This network, which is part of the AZMP, is a key component of the development of better quality remote sensing products to address DFO scientific and management issues.
Operational Oceanography in the Gulf of St. Lawrence
During 2005, the Maurice Lamontagne Institute (IML) laboratory continued to be at the forefront of the development of useful ocean information products for commercial, social and scientific interests. The IML forecasting system is based on research models migrated to the operational level. Daily Ocean Forecasts for the Gulf of St. Lawrence system are freely available on the St. Lawrence Observatory website, http://slgo.ca/en/ocean/context.html
The IML microcosm demonstrates the large range of activities and benefits associated with operational oceanography. In partnership with other agencies that collect related information (e.g., the Meteorological Service of Canada, Canadian Ice Service ice charts, Canadian Hydrographic Service water level observations, the Great Lakes outflow forecast from Environment Canada, the flow forecast from the Ottawa River Board Secretariat) IML maintains programs to make additional routine observations of the marine environment. IML use this information, together with coupled ocean-atmosphere-sea ice forecast models, to provide operational services for specific end users and others through web-based dissemination.
Examples of services include: the Gulf of St. Lawrence daily forecast of surface currents; sea ice concentration and thickness for ship routing for the Canadian Coast Guard Environmental Emergency Service, to use in oil-spill trajectory forecasts and for Search and Rescue Systems; 30-Day water level forecast for the St. Lawrence River; and fresh water flow nowcasting at Quebec City. The system provides an excellent example of what is being done in operational oceanography and how it benefits Canadians.
Online Scientific Data and Information
The DFO Science home page is found at: http://www.dfo-mpo.gc.ca/science The Science online clientele has been steadily growing over the years and is increasingly interested in, and dependent on, DFO aquatic science data and products. The rapid evolution of web technologies constantly brings a range of new possibilities allowing DFO Science to explore and develop additional data integration mechanisms in order to increase data accessibility within DFO and also to achieve interoperability between DFO and its external collaborators.
Under its national umbrella, DFO Science operates several unique web portals catering to specialized science interests. For example, since January 2000, the St. Lawrence Observatory (OSL) Internet Portal (http://ogsl.ca/en.html) has been providing access to scientific data and information about a variety of topics such as ecosystem modelling, biodiversity, climate and environment, experimental biology, remote sensing, and fisheries research. Although mainly focused on the St. Lawrence ecosystem, the OSL portal also features elements reaching beyond the regional boundaries, including web products and applications such as dynamic web access to the national sea surface temperature map archives and the results and models of an ecosystem comparative dynamics program for the Northwest Atlantic. Access to the Centre of Expertise on Marine Mammal Research is also achieved through the OSL portal. Work is now under way inside DFO Science to increase the web presence of the Centres of Expertise and to make information about their research more accessible to national and international partners.
Strategic Science Outreach
DFO Science operates a Strategic Science Outreach unit which is instrumental in building awareness of the importance of DFO's scientific work as an aid to building a science culture in Canada. The unit manages external alliances and partnerships among federal and provincial partners related to science conferences and exhibits at national science centres, outreach activities with non-governmental organizations that contribute to science learning and curricula, and activities involving staff such as internal and external lectures on science. It helps to implement advice from the external Science Advisory Council, a group of ex-officio science and science communications experts who advise the DFO Science management team during the year. It contributes to internal science communication, provides guidance on science activities for external communications and prepares many presentations and reports on DFO Science, such as this annual report. A particular success of the unit is its popular series of science feature stories, which anyone in the public can subscribe to online: http://www.dfo-mpo.gc.ca/science/Publications/article/index-eng.aspPrevious | Table of Contents | Next
