    • Climate change impacts on sea-ice ecosystems and associated ecosystem services 

      Steiner, Nadja; Bowman, Jeff; Campbell, Karley; Chierici, Melissa; Eronen-Rasimus, Eeva; Falardeau, Marianne; Flores, Hauke; Fransson, Agneta; Herr, Helena; Insley, Stephen J.; Kauko, Hanna Maria; Lannuzel, Delphine; Loseto, Lisa; Lynnes, Amanda; Majewski, Andy; Meiners, Klaus M.; Miller, Lisa; Michel, Loic; Moreau, Sebastien; Nacke, Melissa; Nomura, Daiki; Tedesco, Letizia; van Franeker, Jan Andries; Leeuwe, Maria van; Wongpan, Pat (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-10-13)
      A rigorous synthesis of the sea-ice ecosystem and linked ecosystem services highlights that the sea-ice ecosystem supports all 4 ecosystem service categories, that sea-ice ecosystems meet the criteria for ecologically or biologically significant marine areas, that global emissions driving climate change are directly linked to the demise of sea-ice ecosystems and its ecosystem services, and that the ...

    • 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 ...

    • The importance of turbulent ocean–sea ice nutrient exchanges for simulation of ice algal biomass and production with CICE6.1 and Icepack 1.2 

      Duarte, Pedro; Assmy, Philip; Campbell, Karley; Sundfjord, Arild (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-01-31)
      Different sea ice models apply unique approaches in the computation of nutrient diffusion between the ocean and the ice bottom, which are generally decoupled from the calculation of turbulent heat flux. A simple molecular diffusion formulation is often used. We argue that nutrient transfer from the ocean to sea ice should be as consistent as possible with heat transfer, since all of these fluxes ...

    • Polar oceans and sea ice in a changing climate 

      Willis, Megan; Lannuzel, Delphine; Else, Brent; Angot, Helene; Campbell, Karley; Delille, Bruno; Hayashida, Hakase; Lizotte, Martine; Loose, Bruce; Meiners, Klaus; Miller, Lisa; Moreau, Sebastien; Nomura, Daiki; Prytherch, John; Schmale, Julia; Steiner, Nadja; Tedesco, Letizia; Thomas, Jennie; Crabeck, Odile (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-10-18)
      Polar oceans and sea ice cover 15% of the Earth’s ocean surface, and the environment is changing rapidly at both poles. Improving knowledge on the interactions between the atmospheric and oceanic realms in the polar regions, a Surface Ocean–Lower Atmosphere Study (SOLAS) project key focus, is essential to understanding the Earth system in the context of climate change. However, our ability to ...
