Atlantic Cod Likelihood of Presence for Canadian Oil Spill Response Planning

Fisheries and Oceans Canada scientists analyzed bottom trawl survey data to model the likelihood of Atlantic Cod presence in specific marine areas. This dataset was created for the National Environmental Emergency Center to inform oil spill response planning. The data is published by the Coastal Ecosystems Science Division and was last updated in March 2026.

Use Cases

• Modeling species habitat suitability based on stratified random trawl survey data.
• Informing marine spatial planning for oil spill contingency based on cod presence likelihood.
• Assessing ecosystem vulnerability for emergency response in pilot planning areas.

Strengths

• Data originates from a stratified random bottom trawl survey design conducted by Fisheries and Oceans Canada.
• Available in multiple formats including CSV and ESRI REST for geospatial analysis.
• Dataset is versioned and follows a specific data model for the National Environmental Emergency Center.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and spatial resolution are unknown, which may limit suitability assessment.
• Data may reflect geographic and temporal bias inherent to the specific survey trawls.
