    • 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 ...

    • Younger Dryas ice margin retreat triggered by ocean surface warming in central-eastern Baffin Bay 

      Oksman, Mimmi; Weckström, Kaarina; Miettinen, Arto; Juggins, Stephen; Divine, Dmitry V; Jackson, Rebecca; Telford, Richard; Korsgaard, Niels J.; Kučera, Michal (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-10-18)
      The transition from the last ice age to the present-day interglacial was interrupted by the Younger Dryas (YD) cold period. While many studies exist on this climate event, only few include high-resolution marine records that span the YD. In order to better understand the interactions between ocean, atmosphere and ice sheet stability during the YD, more high-resolution proxy records from the Arctic, ...
