Fisheries and Oceans Canada conducted offshore surveys of marine fishes and ecosystems on the Canadian Beaufort Shelf and slope in August and early September. The Beaufort Regional Environmental Assessment-Marine Fishes Project (2012-2014) and Canadian Beaufort Sea-Marine Ecosystem Assessment (2017-present) integrate oceanography, food web linkages, and physical-biological couplings. Sampling was conducted from the F/V Frosti at stations along transects spanning depths from 20 to 1000 meters.
Use Cases
- Modeling pteropod population dynamics based on abundance data.
- Assessing shell dissolution rates as an indicator of ocean acidification.
- Analyzing spatial and inter-annual variability of zooplankton communities.
- Studying food web linkages by integrating zooplankton data with other ecosystem components.
- Investigating physical-biological couplings in the context of climate-driven change.
Strengths
- Data collection spans multiple years from 2012 to the present.
- Sampling covers a depth range from 20 to 1000 meters.
- Projects integrate multiple disciplines including oceanography and biogeochemistry.
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 and temporal bias inherent to the specific survey periods and locations.
