Infographic: Ocean sampling technologies
Description: Ocean sampling technologies
An illustrated diagram shows a simplified side view of the ocean and coastline with multiple types of sampling technologies used to collect data about ocean science. Each illustration is linked to a number describing the technology.
Ocean Sampling Technologies
Technologies—old and new—help to fill gaps in knowledge of Canada’s vast and complex oceans.
- Oceanographic missions support multiple technologies and ocean monitoring.
- Small drones with cameras are used to take aerial photos of habitats and species.
- Buoys and other moorings use sensors to take frequent measurements of ocean conditions at a single location for up to a year.
- Aerial surveys are used to monitor marine mammals, seabirds, and habitats.
- LiDAR (light detection and ranging) is a remote sensing technology used to monitor habitats from the air.
- Research vessels are used to conduct multispecies and acoustic surveys.
- Satellites gather data and images year-round about temperature, sea ice, and phytoplankton.
- Observers document occurrences of seabirds and marine mammals.
- Rosettes collect water samples and carry sensors to measure environmental conditions throughout the water column.
- ROVs (remotely operated vehicles) explore habitats far below the surface.
- Plankton nets collect phytoplankton and zooplankton samples.
- Satellite tagging tracks migratory species such as turtles, fish, sharks, mammals, and seabirds.
- Gliders and Argo floats travel long distances on very little power to gather ocean climate data.
- Collector plates are used to sample invasive tunicate species that attach to them.
- Trawl nets collect samples of invertebrates and fishes.
- Sonar is used to collect data on fishes and zooplankton in the water column and to conduct hydrographic surveys and classify seafloor habitat.
- SCUBA divers collect samples and data in coastal areas.
