Marine ecosystem stressors in the Arctic 370 200 Ocean Decade

Lead institution:

Fisheries and Oceans Canada – Canada

Using traditional knowledge and climate model downscaling to assess impacts on the marine ecosystem and subsistence fisheries, the project aims at providing improved understanding of how oceanographic processes in the Arctic impact marine ecosystems, including abundance, distribution and patterns of phytoplankton and fish assemblages in a changing climate.

Model evaluations include trends and projections of cumulative stressors such as ocean acidification, deoxygenation, warming, increased wave states and loss of sea-ice associated ecosystems and related ecosystem services and focus on the Inuvialuit Settlement Region (ISR) and marine protected areas (MPAs) in the Canadian Arctic. The project includes model refinements such as downscaling to coastal areas to better represent Inuvialuit communities and link with community based monitoring (CBM).
