• Ballasting by cryogenic gypsum enhances carbon export in a Phaeocystis under-ice bloom 

      Wollenburg, JE; Katlein, C; Nehrke, Gernot; Nöthig, E.-M; Matthiessen, J; Wolf-Gladrow, Dieter A.; Nikolopoulos, A.; Gazquez-Sanchez, F; Rossmann, L; Assmy, Philipp; Babin, Marcel; Bruyant, F; Beaulieu, Michaël; Dybwad, Christine; Peeken, Ilka (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-05-16)
      Mineral ballasting enhances carbon export from the surface to the deep ocean; however, little is known about the role of this process in the ice-covered Arctic Ocean. Here, we propose gypsum ballasting as a new mechanism that likely facilitated enhanced vertical carbon export from an under-ice phytoplankton bloom dominated by the haptophyte Phaeocystis. In the spring 2015 abundant gypsum crystals ...
    • Structure and function of the western Baffin Bay coastal and shelf ecosystem

      Arctic marine species, from benthos to fish and mammals, are essential for food security and sovereignty of Inuit people. Inuit food security is dependent on the availability, accessibility, quality, and sustainability of country food resources. However, climate change effects are threatening Inuit food systems through changes in abundance and nutritional quality of locally harvested species, ...
    • Towards a unifying pan-arctic perspective: A conceptual modelling toolkit 

      Wassmann, Paul; Carmack, E.; Bluhm, Bodil; Duarte, Carlos M.; Berge, Jørgen; Brown, K.; Grebmeier, Jacqueline M.; Holding, Johnna; Kosobokova, Ksenia; Kwok, R.; Matrai, Patricia A.; Agusti, S.; Babin, Marcel; Bhatt, Uma S.; Eicken, Hajo; Polyakov, Igor V.; Rysgaard, Søren; Huntington, Henry P. (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-10-17)
      The Arctic Ocean is overwhelmingly forced by its lateral boundaries, and interacts with, the global system. For the development of nested conceptual models of the Arctic Ocean ecosystem we here choose the full pan-Arctic as our focal scale. Understanding the pan-Arctic scale, however, requires that we look at the underlying scales of its major components, by considering regionality, connectivity and ...
    • Zooplankton assemblages along the North American Arctic: Ecological connectivity shaped by ocean circulation and bathymetry from the Chukchi Sea to Labrador Sea 

      Darnis, Gérald; Geoffroy, Maxime; Dezutter, Thibaud; Aubry, Cyril; Massicotte, Philippe; Brown, Tanya; Babin, Marcel; Cote, David; Fortier, Louis (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-11-09)
      We defined mesozooplankton biogeography in the North American Arctic to elucidate drivers of biodiversity, community structure, and biomass of this key component of the Arctic marine ecosystem. A multivariate analysis identified four mesozooplankton assemblages: Arctic-oceanic, Arctic-shelf, Coastal-Hudson, and Labrador Sea. Bathymetry was a major driver of the distribution of these assemblages. ...
