    • Deglacial bottom water warming intensified Arctic methane seepage in the NW Barents Sea 

      El Bani Altuna, Naima; Rasmussen, Tine Lander; Ezat, Mohamed; Vadakkepuliyambatta, Sunil; Groeneveld, Jeroen; Greaves, Mervyn (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-09-09)
      Changes in the Arctic climate-ocean system can rapidly impact carbon cycling and cryosphere. Methane release from the seafloor has been widespread in the Barents Sea since the last deglaciation, being closely linked to changes in pressure and bottom water temperature. Here, we present a post-glacial bottom water temperature record (18,000–0 years before present) based on Mg/Ca in benthic foraminifera ...

    • 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 (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-07-20)
      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 Vestbrona Carbonate Field (VCF) seep site on the Norwegian shelf (63°28′N, 6° 31′E, ∿270 m water depth). Free gas was mainly composed of microbial methane. Sediment porewater ...
