Hydrography, inorganic nutrients and chlorophyll a linked to sea ice cover in the Atlantic Water inflow region north of Svalbard
(Journal article; Tidsskriftartikkel; Peer reviewed, 2023-11-04)Changes in the inflow of Atlantic Water (AW) and its properties to the Arctic Ocean bring more warm water, contribute to sea ice decline, promote borealisation of marine ecosystems, and affect biological and particularly primary productivity in the Eurasian Arctic Ocean. One of the two branches of AW inflow follows the shelf break north of Svalbard, where it dominates oceanographic conditions, ... -
Abrupt permafrost thaw triggers activity of copiotrophs and microbiome predators
(Journal article; Tidsskriftartikkel; Peer reviewed, 2023-10-05)Permafrost soils store a substantial part of the global soil carbon and nitrogen. However, global warming causes abrupt erosion and gradual thaw, which make these stocks vulnerable to microbial decomposition into greenhouse gases. Here, we investigated the microbial response to abrupt in situ permafrost thaw. We sequenced the total RNA of a 1 m deep soil core consisting of up to 26 500-year-old permafrost ... -
Atlantification influences zooplankton communities seasonally in the northern Barents Sea and Arctic Ocean
(Journal article; Tidsskriftartikkel; Peer reviewed, 2023-09-29)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 already been documented in the southern and central Barents Sea, less is known about the degree of Atlantification in the northern Barents Sea and Arctic Ocean.

Vertical Carbon Export in a Changing Arctic Seasonal Ice Zone: Composition and seasonality in the area north of Svalbard and in an Arctic glacial fjord
(Doctoral thesis; Doktorgradsavhandling, 2023-12-11)The ocean’s biological carbon pump (BCP) is a vital part of the global carbon cycle as it produces, transforms, and transfers organic carbon from the surface ocean to the deep. To model the oceans capacity to store carbon today and in the future, we need to understand these processes well. In the Eurasian Arctic, the marine ecosystems who control most of the BCP face a rapid decline in sea ice cover, ... -
