Biological and chemical marine data: BioChem database

BioChem is an archive of marine biological and chemical data maintained by Fisheries and Oceans Canada (DFO). It holds biological and chemical data that are:
- from department research initiatives
- collected in areas of Canadian interest
The data held in BioChem are divided into 2 functional areas, which are:
- discrete data, usually from water bottle sampling, including:
- dissolved oxygen
- species counts
- biomass measurements
While the data support climate research, they may also be used for other purposes. These include improving our understanding of ecosystem variability, ground-truthing satellite data, and supporting fisheries research.
Users must register to use BioChem. You must login through GCKey to request an account.
Once you have your account information, you may use the:
- query application to extract data
- edit application to load or edit data (reserved for DFO data managers)
We've identified content-related issues after an internal review of Maritimes Region BioChem data.
The affected data will be unavailable until we can complete further reviews. We'll make the data available again to BioChem query users as we review each dataset and address the issues.
If you require data loaded by Maritimes Region (generally the Northwest Atlantic), email DataServicesDonnees@dfo-mpo.gc.ca. Provide details, including geographic coordinates and temporal limits.
We'll review requests and provide data whenever possible.
