    • 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 ...

    • Ventilation History of the Nordic Seas Deduced from Pelagic‐Benthic Radiocarbon Age Offsets 

      Telesiński, Maciej M.; Ezat, Mohamed; Muschitiello, Francesco; Bauch, Henning A.; Spielhagen, Robert F. (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-03-24)
      Changes in ocean circulation are considered a major driver of centennial-to-millennial scale climate variability during the last deglaciation. Using four sediment records from the Nordic Seas, we studied radiocarbon ventilation ages in subsurface and bottom waters to reconstruct past variations in watermass overturning. Planktic foraminiferal ages show significant spatial variability over most of ...
