      On 30th March 2022, all Russian participation in ICES was suspended. Although the announcement of the suspension stressed the role of ICES as a “multilateral science organization”, this suspension applied not only to research activities but also to the ICES work providing fisheries advice for the sustainable management of fish stocks and ecosystems. As a result of the suspension, it is not possible ...

    • Ecosystem-related monitoring, assessments and management advices for the Norwegian, Barents and North Seas

    • New insights into the Barents Sea Calanus glacialis population dynamics and distribution 

      Aarflot, Johanna Myrseth; Eriksen, Elena; Prokopchuk, Irina P.; Svensen, Camilla; Søreide, Janne; Wold, Anette; Skogen, Morten D. (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-08-18)
      Arctic copepods are major grazers and vital food for planktivores in polar ecosystems but challenging to observe due to remoteness and seasonal sea ice coverage. Models offer higher spatio-temporal resolution, and individual-based models (IBMs) are useful since they incorporate individual variability which characterizes most copepod populations. Here, we present an IBM of the Arctic copepod Calanus ...

    • The record-warm Barents Sea and 0-group fish response to abnormal conditions 

      Eriksen, Elena; Bagøien, Espen; Strand, Espen; Primicerio, Raul; Prokhorova, Tatiana; Trofimov, Alexander; Prokopchuk, Irina (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-05-25)
      The Barents Sea is a nursery area for many commercially and ecologically important fish stocks, and this whole region is presently subject to rapid climatic change from a cold period in the 1980s to a record warm period in the latest decade, with a peak in 2016. The present study focuses exclusively on year 2016, which was characterized by record warm air and seawater and an exceptionally large ...

    • Spatial and temporal changes in the Barents Sea pelagic compartment during the recent warming 

      Eriksen, Elena; Skjoldal, Hein Rune; Gjøsæter, Harald; Primicerio, Raul (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-01-11)
      The Barents Sea has experienced substantial warming over the last few decades with expansion of relatively warm Atlantic water and reduction in sea ice. Based on a review of relevant literature and additional analyses, we report changes in the pelagic compartment associated with this warming using data from autumn surveys (acoustic capelin, 0-group fish, and ecosystem surveys). We estimated ...

    • Spatio-temporal turnover and drivers of bentho-demersal community and food web structure in a high-latitude marine ecosystem 

      Pecuchet, Laurene; Jørgensen, Lis Lindal; Dolgov, Andreyv V.; Eriksen, Elena; Husson, Berengere; Skern-Mauritzen, Mette; Primicerio, Raul (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-06-14)
      Aim: Assess the spatial and temporal turnover of bentho-demersal marine fauna by integrating ecological metrics at the community and food web levels and evaluate their main environmental and anthropogenic drivers.<p> <p>Location: Barents Sea. <p>Method: We analysed data of benthic and bentho-pelagic fish and megabenthic invertebrates caught in the Barents Sea ecosystem survey in August–Septem ...

    • Still Arctic? — The changing Barents Sea 

      Gerland, Sebastian; Ingvaldsen, Randi Brunvær; Reigstad, Marit; Sundfjord, Arild; Bogstad, Bjarte; Chierici, Melissa; Hop, Haakon; Renaud, Paul Eric; Smedsrud, Lars Henrik; Stige, Leif Christian; Årthun, Marius; Berge, Jørgen; Bluhm, Bodil Annikki Ulla Barbro; Borgå, Katrine; Bratbak, Gunnar; Divine, Dmitry V; Eldevik, Tor; Eriksen, Elena; Fer, Ilker; Fransson, Agneta; Gradinger, Rolf Rudolf; Granskog, Mats A.; Haug, Tore; Husum, Katrine; Johnsen, Geir; Jonassen, Marius Opsanger; Jørgensen, Lis Lindal; Kristiansen, Svein; Larsen, Aud; Lien, Vidar Surén; Lind, Sigrid; Lindstrøm, Ulf Ove; Mauritzen, Cecilie; Melsom, Arne; Mernild, Sebastian H.; Müller, Malte; Nilsen, Frank; Primicerio, Raul; Søreide, Janne; van der Meeren, Gro Ingleid; Wassmann, Paul (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-11-13)
      The Barents Sea is one of the Polar regions where current climate and ecosystem change is most pronounced. Here we review the current state of knowledge of the physical, chemical and biological systems in the Barents Sea. Physical conditions in this area are characterized by large seasonal contrasts between partial sea-ice cover in winter and spring versus predominantly open water in summer and ...

    • Under-ice observations by trawls and multi-frequency acoustics in the Central Arctic Ocean reveals abundance and composition of pelagic fauna 

      Ingvaldsen, Randi Brunvær; Eriksen, Elena; Gjøsæter, Harald; Engås, Arill; Schuppe, Birte Katarina; Assmann, Karen; Cannaby, Heather Anne; Dalpadado, Padmini; Bluhm, Bodil (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-01-18)
      The rapid ongoing changes in the Central Arctic Ocean call for baseline information on the pelagic fauna. However, sampling for motile organisms which easily escape vertically towed nets is challenging. Here, we report the species composition and catch weight of pelagic fishes and larger zooplankton from 12 trawl hauls conducted in ice covered waters in the Central Arctic Ocean beyond the continental ...
