Bogstad, Bjarte; Dingsør, Gjert Endre; Ingvaldsen, Randi; Gjøsæter, Harald (Journal article; Peer reviewed, 2013-06-14)Cod, haddock and herring in the Barents Sea have strongly variable recruitment. For these three stocks, earlier studies have suggested a high correlation between their recruitment and a positive relationship between high ... -

Fysikk (sirkulasjon, vannmasser og klima)
Ingvaldsen, Randi; Loeng, Harald; Ådlandsvik, Bjørn (Havets ressurser og miljø, Chapter, 2007)The temperatures in the Barents Sea were very high during 2006. The inflow of Atlantic water was both warmer and stronger than earlier, and there has never been observed less ice than in the winter of 2006. The years ... -
Havklimaet i Arktis og den aktuelle situasjonen sommeren 2008 : Arctic Ocean Climate and present situation in summer 2008
Ingvaldsen, Randi; Sundby, Svein; Ådlandsvik, Bjørn (Havforskningsnytt, Working paper, 2008)In late winter 2008 record-high temperatures were observed in the Barents Sea, but the spring and summer temperatures fell below those observed in 2007. There is slightly more ice in the Arctic Ocean than in 2007, but a ... -
Heat in the Barents Sea: transport, storage, and surface fluxes
Smedsrud, L.H.; Ingvaldsen, Randi; Nilsen, Jan Even Øie; Skagseth, Øystein (Journal article; Peer reviewed, 2010)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 ... -
