    • CASCADE-The Circum-Arctic Sediment CArbon DatabasE 

      Martens, Jannik; Romankevich, Evgeny; Semiletov, Igor; Wild, Birgit; Van Dongen, Bart; Vonk, Jorien; Tesi, Tommaso; Shakhova, Natalia; Dudarev, Oleg V.; Kosmach, Denis; Vetrov, Alexander; Lobkovsky, Leopold; Belyaev, Nikolay; Macdonald, Robie W.; Pieńkowski, Anna J.; Eglinton, Timothy I.; Haghipour, Negar; Dahle, Salve; Carroll, Michael L.; Åström, Emmelie; Grebmeier, Jacqueline M.; Cooper, Lee W.; Possnert, Göran; Gustafsson, Örjan (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-06-08)
      Biogeochemical cycling in the semi-enclosed Arctic Ocean is strongly influenced by land–ocean transport of carbon and other elements and is vulnerable to environmental and climate changes. Sediments of the Arctic Ocean are an important part of biogeochemical cycling in the Arctic and provide the opportunity to study present and historical input and the fate of organic matter (e.g., through permafrost ...

    • Developing an observational design for epibenthos and fish assemblages in the Chukchi Sea 

      Iken, Katrin; Mueter, Franz J.; Grebmeier, Jacqueline M.; Cooper, Lee W.; Danielson, Seth L.; Bluhm, Bodil (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-11-14)
      In light of ongoing, and accelerating, environmental changes in the Pacific sector of the Arctic Ocean, the ability to track subsequent changes over time in various marine ecosystem components has become a major research goal. The high logistical efforts and costs associated with arctic work demand the prudent use of existing resources for the most comprehensive information gain. Here, we compare ...

    • Diversity and Distribution of Meroplanktonic Larvae in the Pacific Arctic and Connectivity With Adult Benthic Invertebrate Communities 

      Ershova, Elizaveta; Descôteaux, Raphaëlle; Wangensteen, Owen; Iken, Katrin; Hopcroft, Russ; Smoot, Caitlin; Grebmeier, Jacqueline M.; Bluhm, Bodil (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-08-13)
      Pelagic larval stages (meroplankton) of benthic invertebrates seasonally make up a significant proportion of planktonic communities, as well as determine the distribution of their benthic adult stages, yet are frequently overlooked by both plankton and benthic studies. Within the Arctic, the role of meroplanktonic larvae may be particularly important in regions of inflow from sub-Arctic regions, ...

    • The relationship between patterns of benthic fauna and zooplankton in the Chukchi Sea and physical forcing 

      Pisareva, Maria; Pickart, Robert S.; Iken, Katrin; Ershova, Elizaveta; Grebmeier, Jacqueline M.; Cooper, Lee W.; Bluhm, Bodil; Nobre, Carolina; Hopcroft, Russell R.; Hu, Haoguo; Wang, Jia; Ashjian, Carin; Kosobokova, Ksenia N.; Whitledge, Terry (Journal article; Tidsskriftartikkel; Peer reviewed, 2015-09)
      Using data from a number of summer surveys of the Chukchi Sea over the past decade, we investigate aspects in which the benthic fauna, sediment structure, and zooplankton there are related to circulation patterns and shelf hydrographic conditions. A flow speed map is constructed that reveals the major pathways on the shelf. Regions of enhanced flow speed are dictated by lateral constrictions—i ...

    • Time-series benthic community composition and biomass and associated environmental characteristics in the Chukchi Sea during the RUSALCA 2004–2012 program 

      Grebmeier, Jacqueline M.; Bluhm, Bodil; Cooper, Lee W.; Denisenko, Stanislav G.; Iken, Katrin; Kedra, Monika; Serratos, Carlos (Journal article; Tidsskriftartikkel; Peer reviewed, 2015-09)
      Benthic macrofaunal and epifaunal composition and biomass and associated environmental drivers were evaluated for time-series stations occupied during three cruises of the RUSALCA (Russian-American Long-term Census of the Arctic) program undertaken in August 2004, September 2009, and September 2012. We focus on the benthic communities collected at repeat stations in the southern Chukchi Sea and ...

    • 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 ...

    • Trait-based approaches in rapidly changing ecosystems: A roadmap to the future polar oceans 

      Degen, Renate; Aune, Magnus; Bluhm, Bodil; Cassidy, Camilla; Kędra, Monika; Kraan, Casper; Vandepitte, Leen; Włodarska-Kowalczuk, Maria; Zhulay, Irina; Albano, Paolo G.; Bremner, Julie; Grebmeier, Jacqueline M.; Link, Heike; Morata, Nathalie; Nordström, Marie C.; Shojaei, Mehdi Ghodrati; Sutton, Lauren; Zuschin, Martin (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-04-30)
      Polar marine regions are facing rapid changes induced by climate change, with consequences for local faunal populations, but also for overall ecosystem functioning, goods and services. Yet given the complexity of polar marine ecosystems, predicting the mode, direction and extent of these consequences remains challenging. Trait-based approaches are increasingly adopted as a tool by which to explore ...
