    Dense, cold waters formed on Antarctic continental shelves descend along the Antarctic continental margin, where they mix with other Southern Ocean waters to form Antarctic Bottom Water (AABW). AABW then spreads into the ...
  • Supermodeling Improving Predictions with an Ensemble of Interacting Models

    The rapid melt of snow and sea ice during the Arctic summer provides a significant source of low-salinity meltwater to the surface ocean on the local scale. The accumulation of this meltwater on, under, and around sea ice ...
  • Connecting the drops: Exploring precipitation changes from a process and weather perspective 

    Konstali, Kjersti (Doctoral thesis, 2024-03-22)
    Nedbør er kilden til en av de viktigste ressursene for mennesker: ferskvann. På den andre siden kan ekstremnedbør utgjøre en trussel i form av flom og skred. Det er derfor avgjørende å fastslå hvordan nedbøren har forandret ...

  • Present and future drivers of Arctic sea ice variability 

    Dörr, Jakob Simon (Doctoral thesis, 2024-03-07)
    Havisdekket i Arktis har blitt gradvis redusert de siste tiårene. Isdekket varierer likevel betydelig fra år til år, og fra tiår til tiår på grunn av naturlige (interne) variasjoner i klimasystemet. Slike interne variasjoner ...
