• 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 ...
    • Lack of detectable chemosynthesis at a sponge dominated subarctic methane seep 

      Sinner, Melina; Hong, Wei-Li; Michel, Loïc N.; Vadakkepuliyambatta, Sunil; Knies, Jochen Manfred; Sen, Arunima (Peer reviewed; Journal article, 2023)
      We used high-resolution imagery within a Geographic Information System (GIS), free gas and porewater analyses and animal bulk stable isotope measurements to characterize the biotic and abiotic aspects of the newly discovered ...
