The Southampton Island Marine Ecosystem Project, 2019 Cruise Report, 2-29 August, MV William Kennedy
Climate warming is forcing rapid change to Canada’s marine Arctic icescape (Hochheim and Barber 2010) and its associated ecosystem, while the increasing ice-free season is supporting an ever-increasing industrial presence in the North. With over two-thirds of Canada’s coastline being located in the...

Climate warming is forcing rapid change to Canada’s marine Arctic icescape (Hochheim and Barber 2010) and its associated ecosystem, while the increasing ice-free season is supporting an ever-increasing industrial presence in the North. With over two-thirds of Canada’s coastline being located in the North and the fact that nearshore waters represent some of the most productive Arctic regions, there is a need to improve our understanding of marine ecosystem processes in the sensitive Arctic coastal zone. The marine region around Southampton Island, northwest Hudson Bay (Nunavut), encompasses one of Canada’s largest summer and winter aggregations of Arctic marine mammals, providing multiple ecosystem services. This biological hotspot has supported local human habitation for millennia with confirmed Dorset, Thule, and Sadlermiut occupation sites (Collins 1956; Clark 1980; McGhee 1970), and is still crucial to the subsistence economy of local communities today. The region has also been a marine mammal management focus of Fisheries and Oceans Canada (DFO) for decades and supports two sea bird sanctuaries, yet we know surprisingly little of the region’s oceanography, productivity or biological community below these top trophic levels. This fact highlights a major management risk, severely limiting our ability to understand and predict changes to this unique and productive marine ecosystem. Exacerbating this risk are pressures posed by the ongoing climate changes and an increasing industrial presence. Therefore, we undertook an oceanographic study called the Southampton Island Marine Ecosystem Project (SIMEP), funded by the MEOPAR Network of Centres of Excellence (NCE).
