This estimate is expected to increase with future studies. Benthic invertebrates are important ecosystem components as food for fishes, marine mammals, seabirds and humans. The Benthos Expert Network of the Circumpolar Biodiversity Monitoring Program (CBMP) aggregated and reviewed information on the population status and trends of macro- and megabenthic invertebrates across eight Arctic Marine Areas as well as the state of current monitoring efforts for these communities. Drivers are affecting benthic communities on a variety of scales, ranging from pan-Arctic (related to climate change, such as warming, ice decline and acidification) to regional or local scales (such as trawling, river/glacier discharge, and invasive species). Long-term benthic monitoring efforts have largely focused on macro- and megabenthic communities of the Chukchi and Barents Seas. Recently, they are increasing in waters off Greenland and Iceland, as well as in the Canadian Arctic and the Norwegian Sea. All other Arctic Marine Areas are lacking long-term monitoring. The presentation will summarize current level of knowledge and monitoring across the Arctic, drivers of observed trends, and knowledge and monitoring gaps.
