    • Sea ice and primary production proxies in surface sediments from a High Arctic Greenland fjord: Spatial distribution and implications for palaeoenvironmental studies 

      Ribeiro, Sofia; Sejr, Mikael K.; Limoges, Audrey; Heikkilä, Maija; Andersen, Thorbjørn Joest; Tallberg, Petra; Weckström, Kaarina; Husum, Katrine; Forwick, Matthias; Dalsgaard, Tage; Massé, Guillaume; Seidenkrantz, Marit-Solveig; Rysgaard, Søren (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-01-23)
      In order to establish a baseline for proxy-based reconstructions for the Young Sound–Tyrolerfjord system (Northeast Greenland), we analysed the spatial distribution of primary production and sea ice proxies in surface sediments from the fjord, against monitoring data from the Greenland Ecosystem Monitoring Programme. Clear spatial gradients in organic carbon and biogenic silica contents reflected ...

    • Vertical redistribution of principle water masses on the Northeast Greenland Shelf 

      Gjelstrup, Caroline V.B.; Sejr, Mikael K.; de Steur, Laura; Schou Christiansen, Jørgen; Granskog, Mats A.; Koch, Boris P.; Møller, Eva Friis; Winding, Mie H.S.; Stedmon, Colin A. (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-12-10)
      The Northeast Greenland shelf (NEGS) is a recipient of Polar Water (PW) from the Arctic Ocean, Greenland Ice Sheet melt, and Atlantic Water (AW). Here, we compile hydrographical measurements to quantify long-term changes in fjords and coastal waters. We find a profound change in the vertical distribution of water masses, with AW shoaling >60 m and PW thinning >50 m since early 2000’s. The properties ...
