• Chemosynthesis influences food web and community structure in high-Arctic benthos 

      Åström, Emmelie K. L.; Carroll, Michael L.; Sen, Arunima; Niemann, Helge; Ambrose Jr., William G.; Lehmann, Moritz F.; Carroll, JoLynn (Peer reviewed; Journal article, 2019)
      Cold seeps are locations where seafloor communities are influenced by the seepage of methane and other reduced compounds from the seabed. We examined macro-infaunal benthos through community analysis and trophic structure ...
    • Cold seeps in a warming Arctic : Insights for benthic ecology 

      Åström, Emmelie; Sen, Arunima; Carroll, Michael Leslie; Carroll, JoLynn (Peer reviewed; Journal article, 2020)
      Cold-seep benthic communities in the Arctic exist at the nexus of two extreme environments; one reflecting the harsh physical extremes of the Arctic environment and another reflecting the chemical extremes and strong ...
    • Image based quantitative comparisons indicate heightened megabenthos diversity and abundance at a site of weak hydrocarbon seepage in the southwestern Barents Sea 

      Sen, Arunima; Chitkara, Chestaa; Hong, Wei-Li; Lepland, Aivo; Cochrane, Sabine; Di Primio, Rolando; Brunstad, Harald (Peer reviewed; Journal article, 2019)
      Background. High primary productivity in the midst of high toxicity defines hydrocarbon seeps; this feature usually results in significantly higher biomass, but in lower diversity communities at seeps rather than in the ...
    • Iron cycling in Arctic methane seeps 

      Hong, Wei-Li; Latour, Pauline; Sauer, Simone; Sen, Arunima; Gilhooly, William P.; Lepland, Aivo; Fouskas, Fotios (Peer reviewed; Journal article, 2020)
      Anoxic marine sediments contribute a significant amount of dissolved iron (Fe2+) to the ocean which is crucial for the global carbon cycle. Here, we investigate iron cycling in four Arctic cold seeps where sediments are ...
