    • Asynchronous Accumulation of Organic Carbon and Nitrogen in the Atlantic Gateway to the Arctic Ocean 

      Paulsen, Maria Lund; Seuthe, Lena; Reigstad, Marit; Larsen, Aud; Cape, Matthias; Vernet, Maria (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-11-15)
      Nitrogen (N) is the main limiting nutrient for biological production in the Arctic Ocean. While dissolved inorganic N (DIN) is well studied, the substantial pool of N bound in organic matter (OM) and its bioavailability in the system is rarely considered. Covering a full annual cycle, we here follow N and carbon (C) content in particulate (P) and dissolved (D) OM within the Atlantic water inflow to ...

    • How microbial food web interactions shape the arctic ocean bacterial community revealed by size fractionation experiments 

      Müller, Oliver; Seuthe, Lena; Pree, Bernadette; Bratbak, Gunnar; Larsen, Aud; Paulsen, Maria Lund (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-11-17)
      In the Arctic, seasonal changes are substantial, and as a result, the marine bacterial community composition and functions differ greatly between the dark winter and light-intensive summer. While light availability is, overall, the external driver of the seasonal changes, several internal biological interactions structure the bacterial community during shorter timescales. These include specific ...

    • Kunnskapsstatus for bruk av molekylære verktøy i kartlegging og overvåkning av biologisk mangfold i marine miljø 

      Dunshea, Glenn; Martell, Luis; Bakken, Torkild; Budaeva, Nataliya; Ekrem, Torbjørn; Tandberg, Anne Helene S.; Baussant, Thierry; de Boer, Hugo; Hestetun, Jon Thomassen; Hobæk, Anders; Kallioniemi, Eveliina; Larsen, Aud; Markussen, Stine Svalheim; Mauvisseau, Quentin; Ray, Jessica Louise; Yoccoz, Nigel; Willassen, Endre (Research report; Forskningsrapport, 2021-06-02)
      Denne rapporten er bestilt av Miljødirektoratet fra NorBOL (Norwegian Barcode of Life), et nasjonalt nettverk av forskningsinstitusjoner som koordineres av NTNU Vitenskapsmuseet. Universitetsmuseet i Bergen har hatt prosjektledelsen. Rapporten gir en oppsummering av dagens status på DNA-basert metodikk som verktøy i kartlegging og overvåking av biologisk mangfold i det marine miljø. Fokus har vært ...

    • Multiomics in the central Arctic Ocean for benchmarking biodiversity change 

      Mock, Thomas; Boulton, William; Balmonte, John-Paul; Barry, Kevin; Bertilsson, Stefan; Bowman, Jeff; Buck, Moritz; Bratbak, Gunnar; Chamberlain, Emelia J.; Cunliffe, Michael; Creamean, Jessie; Ebenhöh, Oliver; Eggers, Sarah Lena; Fong, Allison A.; Gardner, Jessie; Gradinger, Rolf Rudolf; Granskog, Mats A.; Havermans, Charlotte; Hill, Thomas; Hoppe, Clara J.M.; Korte, Kerstin; Larsen, Aud; Müller, Oliver; Nicolaus, Anja; Oldenburg, Ellen; Popa, Ovidiu; Rogge, Swantje; Schäfer, Hendrik; Shoemaker, Katyanne; Snoeijs-Leijonmalm, Pauline; Torstensson, Anders; Valentin, Klaus; Vader, Anna; Barry, Kerrie; Chen, I-M A; Clum, Alicia; Copeland, Alex; Daum, Chris; Eloe-Fadrosh, Emiley; Foster, Brian; Foster, Bryce; Grigoriev, Igor V.; Huntemann, Marcel; Ivanova, Natalia; Kuo, Alan; Kyrpides, Nikos C.; Mukherjee, Supratim; Palaniappan, Krishnaveni; Reddy, T.B.K.; Salamov, Asaf; Roux, Simon; Varghese, Neha; Woyke, Tanja; Wu, Dongying; Leggett, Richard M.; Moulton, Vincent; Metfies, Katja (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-10-17)
      Multiomics approaches need to be applied in the central Arctic Ocean to benchmark biodiversity change and to identify novel species and their genes. As part of MOSAiC, EcoOmics will therefore be essential for conservation and sustainable bioprospecting in one of the least explored ecosystems on Earth.

    • 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 ...

    • Synechococcus in the Atlantic Gateway to the Arctic Ocean 

      Paulsen, Maria Lund; Doré, Hugo; Garczarek, Laurence; Seuthe, Lena; Müller, Oliver; Sandaa, Ruth-Anne; Bratbak, Gunnar; Larsen, Aud (Journal article; Tidsskriftartikkel; Peer reviewed, 2016-10-05)
      Increasing temperatures, with pronounced effects at high latitudes, have raised questions about potential changes in species composition, as well as possible increased importance of small-celled phytoplankton in marine systems. In this study, we mapped out one of the smallest and globally most widespread primary producers, the picocyanobacterium Synechococcus, within the Atlantic inflow to ...
