    • Drivers of Interannual Sea Ice Concentration Variability in the Atlantic Water Inflow Region North of Svalbard 

      Lundesgaard, Øyvind; Sundfjord, Arild; Renner, Angelika (Peer reviewed; Journal article, 2021)
      Sea ice concentration along the continental margin of the Arctic Ocean is influenced by a multitude of factors, including local freezing and melting due to atmospheric forcing, lateral advection of sea ice by winds and ...
    • Late summer sea ice segmentation with multi-polarisation SAR features in C- and X-band 

      Fors, Ane Schwenke; Brekke, Camilla; Doulgeris, Anthony Paul; Eltoft, Torbjørn; Renner, Angelika; Gerland, Sebastian (Journal article; Peer reviewed, 2016-02-17)
      In this study, we investigate the potential of sea ice segmentation by C- and X-band multi-polarisation synthetic aperture radar (SAR) features during late summer. Five high-resolution satellite SAR scenes were recorded ...
