    • 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 ...

    • 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 ...
