      Bilt, Willem van der; D'Andrea, William J.; Werner, Johannes; Bakke, Jostein (Journal article; Peer reviewed, 2019)
      Arctic climate is uniquely sensitive to ongoing warming. The feedbacks that drive this amplified response remain insufficiently quantified and misrepresented in model scenarios of future warming. Comparison with paleotemperature ...

      To improve knowledge of marine-terminating glaciers in western Greenland, marine sediment cores from the Ata Sund fjord system, hosting two outlet glaciers, Eqip Sermia and Kangilerngata Sermia, were investigated. The main ...

    • Lake Sediments Reveal Large Variations in Flood Frequency Over the Last 6,500 Years in South-Western Norway

      Andøya on the NW coast of Norway is a key site for understanding the Last Glacial Maximum (LGM) in northern Europe. Controversy has arisen concerning the local conditions, especially about the timing and extent of local ...

    • Late Glacial mountain glacier culmination in Arctic Norway prior to the Younger Dryas 

      Wittmeier, Hella Elisa; Schaefer, Joerg M.; Bakke, Jostein; Rupper, Summer; Paasche, Øyvind; Schwartz, Roseanne; Finkel, Robert C. (Journal article; Peer reviewed, 2020)
      Climate changes during the Late Glacial period (LG; 15-11 ka) as recorded in Greenland and Antarctic ice cores show a bipolar pattern. Between 14.5 ka and 13 ka ago, the northern latitudes experienced the Bølling/Allerød ...

    • Late Holocene canyon-carving floods in northern Iceland were smaller than previously reported 

      Bilt, Willem Godert Maria van der; Barr, Iestyn D.; Berben, Sarah Miche Patricia; hennekam, rick; Lane, Timothy P.; Adamson, Kathryn; Bakke, Jostein (Journal article; Peer reviewed, 2021)
      Catastrophic floods have formed deep bedrock canyons on Earth, but the relationship between peak discharge and bedrock erosion is not clearly understood. This hinders efforts to use geological evidence of these cataclysmic ...

    • Long‑term demise of sub‑Antarctic glaciers modulated by the Southern Hemisphere Westerlies 

      Bakke, Jostein; Paasche, Øyvind; Schaefer, Joerg M.; Timmermann, Axel (Journal article; Peer reviewed, 2021)
      The accelerated melting of ice on the Antarctic Peninsula and islands in the sub-Antarctic suggests that the cryosphere is edging towards an irreversible tipping point. How unusual is this trend of ice loss within the frame ...

    • Mapping of the Subglacial Topography of Folgefonna Ice Cap in Western Norway—Consequences for Ice Retreat Patterns and Hydrological Changes
