    • Aragonite saturation states and pH in western Norwegian fjords: Seasonal cycles and controlling factors, 2005-2009 

      Omar, Abdirahman; Skjelvan, Ingunn; Erga, Svein Rune; Olsen, Are (Copernicus Publications, 2016-07-26)
      The uptake of anthropogenic carbon dioxide (CO2) by the ocean leads to a process known as ocean acidification (OA), which lowers the aragonite saturation state (ΩAr) and pH, and this is poorly documented in coastal ...

    • Arctic Ocean carbon biogeochemistry under climate change and ocean acidification 

      Silyakova, Anna (The University of Bergen, 2013-05-10)
      Human-induced CO2 emissions to the atmosphere cause climate change and ocean acidification. The strongest indicators of climate change and ocean acidification are expected to be found in the Arctic Ocean (AO). The AO ...

    • The Arctic Ocean in a Fresh and Warm Future 

      Nummelin, Aleksi (The University of Bergen, 2016-10-28)
      The Arctic Ocean remains one of the least known ocean regions due to its remote location, year-round sea ice cover, and harsh weather conditions. Today, knowledge of the Arctic atmosphere-sea ice-ocean system increases ...

    • The Arctic Sea Ice - Melting During Summer or not Freezing in Winter? 

      Skaret, Henriette Bærheim (The University of Bergen, 2016-06-01)
      The Arctic sea ice cover has retreated rapidly during the last three decades, concurrent with recent global temperature increase both in the atmosphere and in the ocean. The sea ice cover has experienced a retreat in extent ...
