Mechanisms of Ocean Heat Anomalies in the Norwegian Sea
Asbjørnsen, Helene; Årthun, Marius; Skagseth, Øystein; Eldevik, Tor (Journal article; Peer reviewed, 2019)Ocean heat content in the Norwegian Sea exhibits pronounced variability on interannual to decadal time scales.

Mechanisms underlying recent Arctic atlantification
Asbjørnsen, Helene; Årthun, Marius; Skagseth, Øystein; Eldevik, Tor (Peer reviewed; Journal article, 2020)Recent warming and reduced sea ice concentrations in the Atlantic sector of the Arctic Ocean are the main signatures of ongoing Arctic “Atlantification.” The mechanisms driving the warming trends are nevertheless still ... -
