Barents Sea ice cover reflects Atlantic inflow
Årthun, Marius; Eldevik, Tor; Smedsrud, Lars Henrik; Skagseth, Øystein (Working paper, 2011)The recent Arctic winter sea-ice retreat is most pronounced in the Barents Sea. Using available observations of the Atlantic inflow to the Barents Sea and results from a regional ice-ocean model we assess the role of ... -
A brief history of climate – the northern seas from the Last Glacial Maximum to global warming

Decadal trends in ocean acidification from the Ocean Weather Station M in the Norwegian Sea
Skjelvan, Ingunn; Lauvset, Siv Kari; Johannessen, Truls; Gundersen, Kjell; Skagseth, Øystein (Journal article; Peer reviewed, 2022)The Ocean Weather Station M (OWSM) is situated at a fixed position in the Norwegian Sea, one of the major basins of the Nordic Seas, which represents an important area for uptake of atmospheric CO2 as well as deep water ... -

Heat flux variations in the eastern Norwegian Atlantic Current toward
Orvik, Kjell Arild; Skagseth, Øystein (Geophysical Research Letters;32(2005) L14, Journal article, 2005-07-21) -
Heat in the Barents Sea: Transport, storage, and surface fluxes
Smedsrud, Lars Henrik; Ingvaldsen, Randi; Nilsen, Jan Even Øie; Skagseth, Øystein (Journal article, 2010-01-11)A column model is set up for the Barents Sea to explore sensitivity of surface fluxes and heat storage from varying ocean heat transport. Mean monthly ocean transport and atmospheric forcing are synthesised and force the ... -
The impact of the wind stress curl in the North Atlantic on the Atlantic inflow to the Norwegian Sea toward the Arctic
Orvik, Kjell Arild; Skagseth, Øystein (Peer reviewed; Journal article, 2003-09-04)The Norwegian Atlantic Current (NwAC) through the Norwegian Sea serves as a conduit of warm and saline Atlantic water from the North Atlantic to the Arctic Ocean, an important factor for climate and ecology. In this study, ... -
Mechanisms of Ocean Heat Anomalies in the Norwegian Sea
Asbjørnsen, Helene; Årthun, Marius; Skagseth, Øystein; Eldevik, Tor (Peer reviewed; Journal article, 2019-04)Ocean heat content in the Norwegian Sea exhibits pronounced variability on interannual to decadal time scales. These ocean heat anomalies are known to influence Arctic sea ice extent, marine ecosystems, and continental ... -
Mechanisms underlying recent Arctic atlantification
Asbjørnsen, Helene; Årthun, Marius; Skagseth, Øystein; Eldevik, Tor (Journal article; Peer reviewed, 2020-06-20)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 ... -
Monitoring the Norwegian Atlantic slope current using a single moored current meter
Orvik, Kjell Arild; Skagseth, Øystein (Peer reviewed; Journal article, 2003-01)Monitoring the Atlantic inflow (AI) of warm and saline water into the Nordic Seas (Norwegian, Greenland and Iceland Seas) is of great importance becauce of its impact on climate and ecology in Northern Europe and Arctic. ... -
Monthly to annual variability of the Norwegian Atlantic slope current: connection between the northern North Atlantic and the Norwegian Sea
Skagseth, Øystein (Peer reviewed; Journal article, 2004-03)This study investigated relations between direct current measurements in the Norwegian Atlantic slope current (NwASC), the sea surface height variability from the TOPEX altimeter, and reanalysed mean sea level pressure ... -
Nordic Seas Heat Loss, Atlantic Inflow, and Arctic Sea Ice cover over the last century
