  • 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 ...

  • Arctic sea ice altimetry - advances and current uncertainties 

    Zygmuntowska, Marta (The University of Bergen, 2014-06-11)
    One of the most prominent features of global climate change is the reduction in Arctic sea ice thickness. The main tool to derive sea ice thickness on an Arctic wide scale is altimetry from satellites, yet current estimates ...
