      The northern coast of Svalbard contains high-arctic fjords, such as Rijpfjorden (80°N 22°30′E). This area has experienced higher sea and air temperatures and less sea ice in recent years, and models predict increasing ...
    • Seasonal dynamics of the marine CO2 system in Adventfjorden, a West Spitsbergen fjord 

      Ericson, Ylva; Chierici, Melissa; Falck, Eva; Fransson, Agneta Ingrid; Jones, Elizabeth Marie; Kristiansen, Svein (Journal article; Peer reviewed, 2019)
      Time series of the marine CO2 system and related parameters at the IsA Station, by Adventfjorden, Svalbard, were investigated between March 2015 and November 2017. The physical and biogeochemical processes that govern ...
    • Seasonality of the Physical and Biogeochemical Hydrography in the Inflow to the Arctic Ocean Through Fram Strait 

      Randelhoff, Achim; Reigstad, Marit; Chierici, Melissa; Sundfjord, Arild; Ivanov, Vladimir; Cape, Matthias; Vernet, Maria; Tremblay, Jean-Éric; Bratbak, Gunnar; Kristiansen, Svein (Peer reviewed; Journal article, 2018)
    • Spring bloom nutrient dynamics in the Oslofjord 

      Kristiansen, Svein; Farbrot, Tove; Naustvoll, Lars-Johan (Journal article; Peer reviewed, 2001-09-10)
      Primary production and uptake rates of ammonium, nitrate and silicic acid were measured during the 1996 spring bloom in the Oslofjord, southern Norway, using isotope methodology (14C, 15N and 32Si). Chlorophyll a (chl a) ...
    • Still Arctic? — The changing Barents Sea
