    • Marine CO2 system variability in a high arctic tidewater-glacier fjord system, Tempelfjorden, Svalbard 

      Ericson, Ylva; Falck, Eva; Chierici, Melissa; Fransson, Agneta Ingrid; Kristiansen, Svein (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-05-04)
      The marine CO<sub>2</sub> system in Tempelfjorden (Svalbard) was investigated between August 2015 and December 2017 using total alkalinity, pH, temperature, salinity, oxygen isotopic ratio, and nutrient data. Primary production resulted in the largest changes that were observed in the partial pressure of CO<sub>2</sub> (<i>p</i>CO<sub>2</sub>, 140 μatm) and the saturation state of aragonite ...

    • 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; Tidsskriftartikkel; Peer reviewed, 2019-06-11)
      Time series of the marine CO<sub>2</sub> 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 changes in total alkalinity (TA), total dissolved inorganic carbon (DIC) and the saturation state of the calcium carbonate mineral aragonite (Ω<sub>Ar</sub>) were assessed ...

    • Temporal variability in surface water pCO2 in Adventfjorden (West Spitsbergen) with emphasis on physical and biogeochemical drivers 

      Ericson, Ylva; Falck, Eva; Chierici, Melissa; Fransson, Agneta; Kristiansen, Svein; Platt, Stephen Matthew; Hermansen, Ove; Myhre, Cathrine Lund (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-06-26)
      Seasonal and interannual variability in surface water partial pressure of CO<sub>2</sub> (<i>p</i>CO2) and air‐sea CO<sub>2</sub> fluxes from a West Spitsbergen fjord (IsA Station, Adventfjorden) are presented, and the associated driving forces are evaluated. Marine CO<sub>2</sub> system data together with temperature, salinity, and nutrients, were collected at the IsA Station between March 2015 and ...

    • Variability and decadal trends in the Isfjorden (Svalbard) ocean climate and circulation – An indicator for climate change in the European Arctic 

      Skogseth, Ragnheid; Olivier, Léa L.A.; Nilsen, Frank; Falck, Eva; Fraser, Neil J.; Tverberg, Vigdis; Ledang, Anna Birgitta; Vader, Anna; Jonassen, Marius Opsanger; Søreide, Janne; Cottier, Finlo Robert; Berge, Jørgen; Ivanov, Boris V.; Falk-Petersen, Stig (Journal article; Tidsskriftartikkel; Peer reviewed, 2020)
      Isfjorden, a broad Arctic fjord in western Spitsbergen, has shown significant changes in hydrography and inflow of Atlantic Water (AW) the last decades that only recently have been observed in the Arctic Ocean north of Svalbard. Variability and trends in this fjord’s climate and circulation are therefore analysed from observational and reanalysis data during 1987 to 2017. Isfjorden experienced a ...
