Carbon export in the seasonal sea ice zone north of Svalbard from winter to late summer
Dybwad, Christine; Assmy, Philipp; Olsen, Lasse Mork; Peeken, Ilka; Nikolopoulos, Anna; Krumpen, Thomas; Randelhoff, Achim; Tatarek, Agnieszka; Wiktor, Józef M.; Reigstad, Marit (Peer reviewed; Journal article, 2021)Phytoplankton blooms in the Arctic Ocean's seasonal sea ice zone are expected to start earlier and occur further north with retreating and thinning sea ice cover. The current study is the first compilation of phytoplankton ... -
Dense mesopelagic sound scattering layer and vertical segregation of pelagic organisms at the Arctic-Atlantic gateway during the midnight sun
Priou, Pierre; Nikolopoulos, Anna; Flores, Hauke; Gradinger, Rolf; Kunisch, Eirin; Katlein, Christian; Castellani, Giulia; Linders, Torsten Theodor; Berge, Jørgen; Fisher, Jonathan A.D.; Geoffroy, Maxime (Peer reviewed; Journal article, 2021)Changes in vertical and spatial distributions of zooplankton and small pelagic fish impact the biological carbon pump and the distribution of larger piscivorous fish and marine mammal species. However, their distribution ... -
Methane cycling within sea ice: Results from drifting ice during late spring, north of Svalbard
Verdugo, Josefa; Damm, Ellen; Nikolopoulos, Anna (Peer reviewed; Journal article, 2021)Summer sea ice cover in the Arctic Ocean has declined sharply during the last decades, leading to changes in ice structures. The shift from thicker multi-year ice to thinner first-year ice changes the methane storage ... -
Micro- and macro-habitat selection of Atlantic salmon, (Salmo salar), post-smolts in relation to marine environmental cues
Jensen, Jenny Lovisa Alexandra; Strøm, John Fredrik; Nikolopoulos, Anna; Primicerio, Raul; Skardhamar, Jofrid; Atencio, Benjamin J.; Strand, Jo Espen Tau; Bjørn, Pål Arne; Bøhn, Thomas (Peer reviewed; Journal article, 2022)Atlantic salmon is an economically and culturally important species. The species encounters several natural and man-made threats during its migration between fresh water and the ocean, which in combination may explain its ... -

Pelagic ecosystem dynamics between late autumn and the post spring bloom in a sub-Arctic fjord
Walker, Emily-Zoe Elizabeth; Wiedmann, Ingrid; Nikolopoulos, Anna; Skardhamar, Jofrid; Jones, Elizabeth Marie; Renner, Angelika (Peer reviewed; Journal article, 2022)Marine ecosystems, and particularly fjords, are experiencing an increasing level of human activity on a year-round basis, including the poorly studied winter period. To improve the knowledge base for environmentally ... -
Productive detours – Atlantic water inflow and acoustic backscatter in the major troughs along the Svalbard shelf
Menze, Sebastian; Ingvaldsen, Randi Brunvær; Nikolopoulos, Anna; Hattermann, Tore; Albretsen, Jon; Gjøsæter, Harald (Peer reviewed; Journal article, 2020)Atlantic Water (AW) flowing along the western and northern Svalbard shelf-break extends the Atlantic domain into the Arctic and is the region’s major source of heat, nutrients and advected plankton. We investigated the ... -
Sea trout Salmo trutta in the subarctic: home-bound but large variation in migratory behaviour between and within populations
Strøm, John Fredrik; Jensen, Jenny L. A.; Nikolopoulos, Anna; Nordli, Eivind; Bjørn, Pål Arne; Bøhn, Thomas (Peer reviewed; Journal article, 2021)
