      Synthetic Aperture Radar (SAR) satellite images are used to monitor Arctic sea ice, with systematic data records dating back to 1991. We propose a semi-supervised classification method that separates open water from sea ice and can utilise ERS-1/2, Envisat ASAR, RADARSAT-2 and Sentinel-1 SAR images. The classification combines automatic segmentation with a manual segment selection stage. The ...

    • Making the Arctic predictable: The changing information infrastructure of Arctic weather and sea ice services 

      Knol, Maaike; Arbo, Peter; Duske, Paula; Gerland, Sebastian; Lamers, Machiel; Pavlova, Olga; Sivle, Anders Doksæter; Tronstad, Stein (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-09-19)
      This paper explores the changing infrastructure around weather and sea ice information provisioning for Arctic marine areas. Traditionally, the most important providers of operational information on sea ice and weather conditions are the national sea ice and meteorological services. More recently, the community of Arctic information providers has become more heterogeneous with the establishment of ...

      The System for Assessment of Ecological Condition, coordinated by the Norwegian Environment Agency, is intended to form the foundation for evidence-based assessments of the ecological condition of Norwegian terrestrial and marine ecosystems not covered by the EU Water Framework Directive. The reference condition is defined as “intact ecosystems”, i.e., a condition that is largely unimpacted by modern ...

      Despite the exclusion of the Southern Ocean from assessments of progress towards achieving the Convention on Biological Diversity (CBD) Strategic Plan, the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR) has taken on the mantle of progressing eforts to achieve it. Within the CBD, Aichi Target 11 represents an agreed commitment to protect 10% of the global coastal and ...
    • Seasonal plankton dynamics in Kongsfjorden during two years of contrasting environmental conditions 

      Assmy, Philipp; Kvernvik, Ane Cecilie; Hop, Haakon; Hoppe, Clara J.M.; Chierici, Melissa; David T., Divya; Duarte, Pedro; Fransson, Agneta; García, Laura M.; Patuła, Weronika; Kwaśniewski, Sławomir; Maturilli, Marion; Pavlova, Olga; Tatarek, Agnieszka; Wiktor, Jozef M; Wold, Anette; Wolf, Klara K.E.; Bailey, Allison Michelle (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-02-24)
      Seasonal plankton time-series data are presented from Kongsfjorden from two years with contrasting environmental conditions. Kongsfjorden (west coast of Spitsbergen – 79°N) integrates inputs from Atlantic and Arctic waters, and glacier run-off, and is thus a prime location to study impacts on ecosystem dynamics of key environmental drivers that are relevant across the Arctic. Despite extensive ...
