Climate based multi-year predictions of the Barents Sea cod stock.
Årthun, Marius; Bogstad, Bjarte; Daewel, Ute; Keenlyside, Noel; Sandø, Anne Britt; Schrum, Corinna; Ottersen, Geir (Peer reviewed; Journal article, 2018-10-24)Predicting fish stock variations on interannual to decadal time scales is one of the major issues in fisheries science and management. Although the field of marine ecological predictions is still in its infancy, it is ... -
Growth portfolios buffer climate-linked environmental change in marine systems
Campana, Steven E.; Smolinski, Szymon; Black, Bryan A.; Morrongiello, John R.; Alexandroff, Stella J.; Andersson, Carin; Bogstad, Bjarte; Butler, Paul G.; Denechaud, Côme; Frank, David C.; Geffen, Audrey J.; Godiksen, Jane Aanestad; Grønkjær, Peter; Hjörleifsson, Einar; Jónsdóttir, Ingibjörg G.; Meekan, Mark; Mette, Madelyn; Tanner, Susanne E.; van der Sleen, Peter; von Leesen, Gotje (Journal article; Peer reviewed, 2022)Large-scale, climate-induced synchrony in the productivity of fish populations is becoming more pronounced in the world's oceans. As synchrony increases, a population's “portfolio” of responses can be diminished, in turn ... -
Skilful prediction of cod stocks in the North and Barents Sea a decade in advance
Koul, Vimal; Sguotti, Camilla; Årthun, Marius; Brune, Sebastian; Dusterhus, Andre; Bogstad, Bjarte; Ottersen, Geir; Baehr, Johanna; Schrum, Corinna (Journal article; Peer reviewed, 2021)Reliable information about the future state of the ocean and fish stocks is necessary for informed decision-making by fisheries scientists, managers and the industry. However, decadal regional ocean climate and fish stock ... -

Here we review the current state of knowledge of the physical, chemical and biological systems in the Barents Sea. ... -
Temperature exposure in cod driven by changes in abundance
Von Leesen, Gotje; Bogstad, Bjarte; Hjørleifsson, Einar; Ninnemann, Ulysses S; Campana, Steven E. (Journal article; Peer reviewed, 2022)Animals actively select the most suitable habitat in terms of fitness, much of which is mediated by temperature. We reconstructed population abundance, oxygen isotope and temperature chronologies for the Icelandic and the ...
