Annual ecosystem surveys conducted by Fisheries and Oceans Canada monitor trends in species distribution, abundance, and biological condition. The data provides integrated monitoring for fish, invertebrates, hydrographic conditions, zooplankton, and phytoplankton on the Scotian Shelf, Bay of Fundy, and Georges Bank. Surveys follow a stratified random sampling design using bottom otter trawl, CTD rosette, and vertical plankton tows.
Use Cases
- Monitoring fish stock abundance based on bottom trawl catch data
- Analyzing species distribution trends based on stratified random sampling
- Studying hydrographic conditions for the Atlantic Zonal Monitoring Program (AZMP)
- Tracking phytoplankton and zooplankton population dynamics based on plankton tow data
Strengths
- Annual surveys provide consistent, long-term monitoring data
- Integrated ecosystem data includes fish, invertebrates, plankton, and hydrographic conditions
- Data supports the Atlantic Zonal Monitoring Program (AZMP)
- Sampling design follows a stratified random methodology
Limitations
- Column-level documentation is absent; field semantics must be inferred after download
- Row count is unknown, which may limit suitability assessment
- Data may reflect geographic bias inherent to the Scotian Shelf, Bay of Fundy, and Georges Bank region
