    • Arctic Ocean outflow shelves in the changing Arctic: A review and perspectives 

      Michel, Christine; Hamilton, J.; Hansen, Edmond; Barber, Dave; Reigstad, Marit; Iocozza, J; Seuthe, Lena; Niemi, Andrea (Journal article; Tidsskriftartikkel; Peer reviewed, 2015-08-28)
      Over the past decade or so, international research efforts, many of which were part of the International Polar Year, have accrued our understanding of the Arctic outflow shelves. The Arctic outflow shelves, namely the East Greenland Shelf (EGS) and the Canadian Arctic Archipelago (CAA), serve as conduits through which Arctic sea ice and waters and their properties are exported to the North Atlantic. ...

    • Benthic-pelagic trophic coupling in an Arctic marine food web along vertical water mass and organic matter gradients 

      Stasko, Ashley D; Bluhm, Bodil; Michel, Christine; Archambault, Philippe; Majewski, Andrew; Reist, James D; Swanson, Heidi; Power, Michael (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-04-26)
      Understanding drivers of benthic-pelagic coupling in Arctic marine ecosystems is key to identifying benthic areas that may be sensitive to climate-driven changes in hydrography and surface production. We coupled algal biomass and sedimentary characteristics with stable isotope data for 113 fishes and invertebrates in the Canadian Beaufort Sea and Amundsen Gulf to examine how trophic structure was ...

    • Fatty acids and stable isotope signatures of first-year and multiyear sea ice in the Canadian High Arctic 

      Kohlback, Doreen; Duerksen, Steven W.; Lange, Benjamin A.; Charette, Joannie; Reppchen, Anke; Tremblay, Pascal; Campbell, Karley; Ferguson, Steven. H.; Michel, Christine (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-12-21)
      Ice algae are critical components to the lipid-driven Arctic marine food web, particularly early in the spring. As little is known about these communities in multiyear ice (MYI), we aimed to provide a baseline of fatty acid (FA) and stable isotope signatures of sea-ice communities in MYI from the Lincoln Sea and compare these biomarkers to first-year ice (FYI). Significant differences in the relative ...

    • Net heterotrophy in High Arctic first-year and multi-year spring sea ice 

      Campbell, Karley; Lange, Benjamin; Landy, Jack Christopher; Katlein, Christian; Nicolaus, Marcel; Anhaus, Philipp; Matero, Ilkka; Gradinger, Rolf; Charette, Joannie; Duerksen, Steven; Tremblay, Pascal; Rysgaard, Søren; Tranter, Martyn; Haas, Christian; Michel, Christine (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-01-04)
      The net productivity of sea ice is determined by the physical and geochemical characteristics of the ice–ocean system and the activity of organisms inhabiting the ice. Differences in habitat suitability between first-year and multi-year sea ice can affect the ice algal community composition and acclimation state, introducing considerable variability to primary production within each ice type. In ...
