Acoustic detection of the Greenland shark (Somniosus microcephalus) using multifrequency split beam echosounder in Svalbard waters
(Peer reviewed; Journal article, 2022)The conservation status of the long-lived Greenland shark (Somniosus microcephalus) is unknown, and methods for non-invasively estimating local or regional abundances are wanted. Using a multifrequency split beam echosounder ... -
Acoustic scattering layers reveal a faunal connection across the Fram Strait
(Peer reviewed; Journal article, 2020)Acoustic scattering layers (SL) at various depths are common phenomena in most oceans, but the organisms that make up these layers vary and so does their density, and hence the backscattered energy. During two crossings ... -
Atlantification influences zooplankton communities seasonally in the northern Barents Sea and Arctic Ocea
(Peer reviewed; Journal article, 2023)The Barents Sea is undergoing rapid ocean warming with less sea ice and increased Atlantic inflow, shifting the pelagic ecosystem towards a more boreal one, a process referred to as Atlantification. While such changes have ... -
Atlantification influences zooplankton communities seasonally in the northern Barents Sea and Arctic Ocean
(Peer reviewed; Journal article, 2023)The Barents Sea is undergoing rapid ocean warming with less sea ice and increased Atlantic inflow, shifting the pelagic ecosystem towards a more boreal one, a process referred to as Atlantification. While such changes have ... -
Benthic transition zones in the Atlantic gateway to a changing Arctic ocean
(Peer reviewed; Journal article, 2022)The biogeographic transition from boreal to Arctic marine communities entails a strong taxonomic and functional turnover. Communities living in these areas are being strongly affected by climate warming with rapid ... -
Bioenergetics of egg production in Northeast Atlantic mackerel changes the perception of fecundity type and annual trends in spawning stock biomass
(Peer reviewed; Journal article, 2021)Egg surveys are used worldwide for the estimation of spawning stock biomass (SSB) of small pelagic fish species, requiring detailed knowledge about their reproductive biology. In the present study, we revisit the current ... -
Broad-scale benthic habitat classification of the South Atlantic
(Peer reviewed; Journal article, 2023)Marine Spatial Planning (MSP) has become a priority for many states wanting to develop national blue economy plans and meet international obligations in response to the increasing cumulative impacts of human activities and ... -
Climate effects on temporal and spatial dynamics of phytoplankton and zooplankton in the Barents Sea
(Peer reviewed; Journal article, 2020) -
Cod at drift in the North Sea
(Journal article; Peer reviewed, 2018)There has been a large-scale geographical re-distribution of the North Sea cod stock over the past century, and recent surveys indicate a north-eastern modal distribution. Here we assess the consequences of the contemporary ... -
A deep scattering layer under the North Pole pack ice
(Peer reviewed; Journal article, 2021)The 3.3 million km2 marine ecosystem around the North Pole, defined as the Central Arctic Ocean (CAO), is a blind spot on the map of the world’s fish stocks. The CAO essentially comprises the permanently ice-covered deep ... -
Dense mesopelagic sound scattering layer and vertical segregation of pelagic organisms at the Arctic-Atlantic gateway during the midnight sun
(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 ... -
Diet and trophic structure of fishes in the Barents Sea: the Norwegian-Russian program “Year of stomachs” 2015 - establishing a baseline
(Peer reviewed; Journal article, 2020)There is a long history of investigations of fish diet in the Barents Sea. The focus has been on commercially important fish species and their food consumption, while diet and interactions of other fishes have been studied ... -
Diffusive and advective cross-frontal fluxes of inorganic nutrients and dissolved inorganic carbon in the Barents Sea in autumn
(Peer reviewed; Journal article, 2023)The Atlantic Water, entering the Arctic through the Barents Sea and Fram Strait, is the main source of nutrients in the Arctic Ocean. The Barents Sea is divided by the Polar Front into an Atlantic-dominated domain in the ... -
Diversity and seasonal development of large zooplankton along physical gradients in the Arctic Barents Sea
(Peer reviewed; Journal article, 2023)Due to ongoing climate change, a new Arctic Ocean ecosystem is emerging. Within the framework of the Nansen Legacy project, we investigated the community composition of the large zooplankton and its seasonal development ... -
Earlier sea-ice melt extends the oligotrophic summer period in the Barents Sea with low algal biomass and associated low vertical flux
(Peer reviewed; Journal article, 2023)The decrease in Arctic sea-ice extent and thickness as a result of global warming will impact the timing, duration, magnitude and composition of phytoplankton production with cascading effects on Arctic marine food-webs ... -

Early life growth is affecting timing of spawning in the semelparous Barents Sea capelin (Mallotus villosus)
(Peer reviewed; Journal article, 2021)Capelin (Mallotus villosus) is a forage fish and a key species in the Barents Sea (BS). The BS capelin are semelparous and hence only spawn once along the north coasts of Norway and Russia before they die. The age at ... -
Environmental controls on macrozooplankton and fish distributions over diurnal to seasonal time scales in the northern Barents Sea
(Peer reviewed; Journal article, 2023)We present acoustic observations obtained by bottom mounted echosounders at two locations in the northern Barents Sea and a third on the northern continental slope of the Barents Sea. Data collected over a period of ... -
Environmental stressors may cause unpredicted, notably lagged life-history responses in adults of the planktivorous Atlantic herring
(Peer reviewed; Journal article, 2020)Here we challenge traditional views on the direction of change in teleost body condition and reproductive traits in response to abiotic and biotic factors by studying the data-rich, planktivorous Norwegian spring-spawning ... -
Fish assemblages at the Yermak Plateau and in northern Svalbard waters during the period 2012-2020
(Peer reviewed; Journal article, 2023)During several surveys covering the north-western and northern Svalbard waters, and the deeper Yermak Plateau north of Svalbard during the period 2012–2020, 291 standardized hauls with a demersal trawl were made. All fishes ...
