    • Arctic continental slopes sharp gradients of physical processes affect pelagic and benthic ecosystems. 

      Bluhm, Bodil; Janout, Markus; Danielson, Seth L.; Ellingsen, Ingrid H.; Gavrilo, Maria; Grebmeier, Jaqueline; Hopcroft, Russell R.; Iken, Katrin; Ingvaldsen, Randi Brunvær; Jørgensen, Lis Lindal; Kosobokova, Ksenia N.; Kwok, Ron; Polyakov, Igor V.; Renaud, Paul E.; Carmack, Eddy C. (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-11-20)
      Continental slopes – steep regions between the shelf break and abyssal ocean – play key roles in the climatology and ecology of the Arctic Ocean. Here, through review and synthesis, we find that the narrow slope regions contribute to ecosystem functioning disproportionately to the size of the habitat area (∼6% of total Arctic Ocean area). Driven by inflows of sub-Arctic waters and steered by topography, ...

    • 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 ...
