    • Changes in sea ice cover and ice sheet extent at the Yermak Plateau during the last 160 ka - Reconstructions from biomarker records 

      Kremer, A; Stein, R; Fahl, K.; Ji, Z; Yang, Z; Wiers, Steffen; Matthiessen, J; Forwick, Matthias; Löwemark, Ludvig; O'Regan, M; Chen, J; Snowball, Ian (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-02-15)
      The Yermak Plateau is located north of Svalbard at the entrance to the Arctic Ocean, i.e. in an area highly sensitive to climate change. A multi proxy approach was carried out on Core PS92/039-2 to study glacial-interglacial environmental changes at the northern Barents Sea margin during the last 160 ka. The main emphasis was on the reconstruction of sea ice cover, based on the sea ice proxy ...

    • Exploring late Pleistocene bioturbation on Yermak Plateau to assess sea-ice conditions and primary productivity through the Ethological Ichno Quotient 

      Singh, Akanksha; O’Regan, Matt; Coxall, Helen K.; Forwick, Matthias; Löwemark, Ludvig (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-10-13)
      Central Arctic, interglacial intervals have traditionally been associated with diverse and intense bioturbation, and abundant foraminifera, interpreted as indicating relatively low sea-ice concentrations and productive surface waters, while glacial intervals, typically barren, support the inverse. In this respect, the Yermak Plateau is anomalous. Biomarker studies suggest that glacial intervals were ...
