    • Persistence of Holocene ice cap in northeast Svalbard aided by glacio-isostatic rebound 

      Farnsworth, Wesley Randall; Ingólfsson, Ólafur; Brynjólfsson, Skafti; Allaart, Lis; Kjellman, Sofia Elisabeth; Kjær, Kurt H.; Larsen, Nicolaj K.; Macias-Fauria, Marc; Siggaard-Andersen, Marie-Louise; Schomacker, Anders (Journal article; Tidsskriftartikkel; Peer reviewed, 2024-03-29)
      The deglaciation of the Svalbard-Barents Sea Ice Sheet was driven by relative sea-level rise, the incursion of North Atlantic waters around Spitsbergen, and increasing summer insolation. However, ice retreat was inter rupted by asynchronous re-advances that occurred into high relative seas, during a period associated with warm regional waters and elevated summer temperatures. Better understanding ...

    • Postglacial relative sea level change and glacier activity in the early and late Holocene: Wahlenbergfjorden, Nordaustlandet, Svalbard 

      Schomacker, Anders; Farnsworth, Wesley Randall; Ingólfsson, Ólafur; Allaart, Lis; Håkansson, Lena; Retelle, Michael; Marie-Louise, Siggaard-Andersen; Korsgaard, Niels J.; Rouillard, Alexandra; Kjellman, Sofia Elisabeth (Journal article; Peer reviewed, 2019-05-01)
      Sediment cores from Kløverbladvatna, a threshold lake in Wahlenbergfjorden, Nordaustlandet, Svalbard were used to reconstruct Holocene glacier fluctuations. Meltwater from Etonbreen spills over a threshold to the lake, only when the glacier is significantly larger than at present. Lithological logging, loss-on-ignition, ITRAX scanning and radiocarbon dating of the cores show that Kløverbladvatna ...
