    • The chronology of reindeer hunting on Norway's highest ice patches 

      Pilø, Lars Holger; Finstad, Espen; Bronk Ramsey, Christopher; Martinsen, Julian Robert Post; Solli, Brit; Nesje, Atle; Wangen, Vivian; Callanan, Martin; Barrett, James H. (Peer reviewed; Journal article, 2018-01-24)
      The melting of perennial ice patches globally is uncovering a fragile record of alpine activity, especially hunting and the use of mountain passes. When rescued by systematic fieldwork (glacial archaeology), this evidence ...

    • A low climate threshold for south Greenland Ice Sheet demise during the Late Pleistocene 

      Irvali, Nil; Galaasen, Eirik Vinje; Ninnemann, Ulysses S; Rosenthal, Yair; Born, Andreas; Kleiven, Helga Flesche (Peer reviewed; Journal article, 2020-01-07)
      The Greenland Ice Sheet (GIS) has been losing mass at an accelerating rate over the recent decades. Models suggest a possible temperature threshold between 0.8 and 3.2 °C, beyond which GIS decline becomes irreversible. The ...

    • Norwegian margin outer shelf cracking: a consequence of climate-induced gas hydrate dissociation? 

      Mienert, Jurgen; Vanneste, Maarten; Haflidason, Haflidi; Bünz, Stefan (Peer reviewed; Journal article, 2010)
      A series of en echelon cracks run nearly parallel to the outer shelf edge of the mid-Norwegian margin. The features can be followed in a *60-km-long and *5-km-wide zone in which up to 10-m-deep cracks developed in the ...

    • The potential of sedimentary ancient DNA for reconstructingpast sea ice evolution 

      De Schepper, Stijn; Ray, Jessica Louise; Skaar, Katrine Sandnes; Sadatzki, Henrik; Ijaz, Umer Zeeshan; Stein, Ruediger; Larsen, Aud (Peer reviewed; Journal article, 2019-06-24)
      Sea ice is a crucial component of the Arctic climate system, yet the tools to document the evolution of sea ice conditions onhistorical and geological time scales are few and have limitations. Such records are essential ...
