    • Biogeography of epibenthic assemblages in the central Beaufort Sea 

      Ravelo, Alexandra M.; Bluhm, Bodil; Foster, Nora; Iken, Katrin (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-01-27)
      Benthic communities change drastically in both biomass and community structure with increasing water depth on a global scale, attributed to a combination of food supply, environmental drivers, as well as physiological and competitive capacities. In the Arctic, benthic biogeographic patterns are additionally thought to be a result of the region’s glaciation history. Here, we investigate gross epibenthic ...

    • Growth and production of the brittle stars Ophiura sarsii and Ophiocten sericeum (Echinodermata: Ophiuroidea) 

      Ravelo, Alexandra M.; Konar, Brenda; Bluhm, Bodil; Iken, Katrin (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-03-28)
      Dense brittle star assemblages dominate vast areas of the Arctic marine shelves, making them key components of Arctic ecosystem. This study is the first to determine the population dynamics of the dominant shelf brittle star species, <i>Ophiura sarsii</i> and <i>Ophiocten sericeum</i>, through age determination, individual production and total turnover rate (P:B). In the summer of 2013, <i>O. ...
