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 ... -
From single species surveys towards monitoring of the Barents Sea ecosystem
(Journal article; Peer reviewed, 2017)The Barents Sea, a large, high-latitude shelf sea, has been monitored and investigated for more than a century. More than 1800 occasional expeditions have been organized both by Norway and Russia, and since the1960s the ... -
From Winter to Late Summer in the Northwestern Barents Sea Shelf: Impacts of Seasonal Progression of Sea Ice and Upper Ocean on Nutrient and Phytoplankton Dynamics
(Peer reviewed; Journal article, 2023)Strong seasonality is a key feature of high-latitude systems like the Barents Sea. While the interannual variability and long-term changes of the Barents Sea are well-documented, the seasonal progression of the physical ... -
Harp seal body condition and trophic interactions with prey in Norwegian high Arctic waters in early autumn
(Peer reviewed; Journal article, 2020)In September 2016, a marine ecosystem survey covered all trophic levels from phytoplankton to seals in the Arctic Ocean to the west and north of Svalbard. At the ice edge, 26 harp seals were sampled to assess whether recent ... -
Hydrography, inorganic nutrients and chlorophyll a linked to sea ice cover in the Atlantic Water inflow region north of Svalbard
(Peer reviewed; Journal article, 2023) -
Inorganic carbon and nutrient dynamics in the marginal ice zone of the Barents Sea: Seasonality and implications for ocean acidification
(Peer reviewed; Journal article, 2023)The Barents Sea is a productive Arctic shelf sea experiencing Atlantification with ocean warming, sea ice loss and increased influence of Atlantic Water. The impact of these changes on inorganic carbon and nutrient dynamics ... -
Interannual differences in sea ice regime in the north-western Barents Sea cause major changes in summer pelagic production and export mechanisms
(Peer reviewed; Journal article, 2023)The Barents Sea is a highly dynamic and productive marine ecosystem and a hotspot of global warming. Variability in sea ice extent is a common feature in the Barents Sea with substantial movements of the sea ice edge on ... -
International megabenthic long-term monitoring of a changing arctic ecosystem: Baseline results
(Peer reviewed; Journal article, 2022)The sustainable development and environmental protection of the Arctic ecosystem is on the agenda globally. The Convention of Biological Diversity (CBD) and the UN Sustainable Development Goals call for conserving at least ... -
Key physical processes and their model representation for projecting climate impacts on subarctic Atlantic net primary production: A synthesis
(Peer reviewed; Journal article, 2023)Oceanic net primary production forms the foundation of marine ecosystems. Understanding the impact of climate change on primary production is therefore critical and we rely on Earth System Models to project future changes. ... -
Linking bacterial community structure to advection and environmental impact along a coast-fjord gradient of the Sognefjord, western Norway
(Peer reviewed; Journal article, 2017) -
New insights into the Barents Sea Calanus glacialis population dynamics and distribution
(Peer reviewed; Journal article, 2023)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 ... -
Nutrient concentrations in minke whale faeces and the potential impact on dissolved nutrient pools off Svalbard, Norway
(Peer reviewed; Journal article, 2023)There is increasing interest in assessing the impact of whales on nutrient and carbon cycling in the ocean. By fertilising surface waters with nutrient-rich faeces, whales may stimulate primary production and thus carbon ... -
Ocean acidification state variability of the Atlantic Arctic Ocean around northern Svalbard
(Peer reviewed; Journal article, 2021)The Svalbard shelf and Atlantic Arctic Ocean are a transition zone between northward flowing Atlantic Water and ice-covered waters of the Arctic. Effects of regional ocean warming, sea ice loss and greater influence of ... -
Overwintering distribution, inflow patterns and sustainability of Calanus finmarchicus in the North Sea
(Peer reviewed; Journal article, 2021)Calanoid copepods are key taxa in the North Sea as they are the main food source for many fish stocks, such as herring, mackerel and cod. In this study we use an individual-based model for Calanus finmarchicus embedded in ... -
Productive detours – Atlantic water inflow and acoustic backscatter in the major troughs along the Svalbard shelf
(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 ... -
Rapid fCO2 rise in the northern Barents Sea and Nansen Basin
(Peer reviewed; Journal article, 2023)Maps of surface water fugacity of CO2 (fCO2) over eastern Fram Strait, south-western Nansen Basin, and the north-western Barents Sea (73–84°N, 5–46°E) from September 1997 to December 2020 were made and used to investigate ... -
Recruitment variability of fish stocks in the Barents Sea: Spatial and temporal variation in 0-group fish length of six commercial species during recent decades of warming (1980–2017)
(Peer reviewed; Journal article, 2022)Young-of-the-year (0-group) fish in the Barents Sea have been investigated in an annual joint Norwegian-Russian pelagic trawl survey in autumn, using a standardized procedure since 1980. We use a conceptual framework of ... -
Responding to global warming: New fisheries management measures in the Arctic
(Peer reviewed; Journal article, 2020)The northernmost commercial fisheries in the world take place in the northern Barents Sea up to around 80° N. This is an area where global warming is particularly intense and where large, previously ice-covered areas are ... -
Seasonal and interannual variability in abundance and population development of Calanus finmarchicus at the western entrance to the Barents Sea, 1995–2019
