Food webs and carbon flux in the Barents Sea
Abstract Within the framework of the physical forcing, we describe and quantify the key ecosystem components and basic food web structure of the Barents Sea. Emphasis is given to the energy flowExpand

Seasonal food web structures and sympagic–pelagic coupling in the European Arctic revealed by stable isotopes and a two-source food web model
Abstract We simultaneously followed stable carbon (δ13C) and nitrogen (δ15N) isotopes in a two-source food web model to determine trophic levels and the relative importance of open water- andExpand

The marine ecosystem of Kongsfjorden, Svalbard
Kongsfjorden is a glacial fjord in the Arctic (Svalbard) that is influenced by both Atlantic and Arctic water masses and harbours a mixture of boreal and Arctic flora and fauna. Inputs from largeExpand

Physical and biological characteristics of the pelagic system across Fram Strait to Kongsfjorden
Abstract The Fram Strait is very important with regard to heat and mass exchange in the Arctic Ocean, and the large quantities of heat carried north by the West Spitsbergen Current (WSC) influenceExpand

Energy Flow through the Marine Ecosystem of the Lancaster Sound Region, Arctic Canada
This paper synthesizes the trophic dynamics of a Canadian arctic marine ecosystem in so far as it is known, using new data on primary production, zooplankton, the bivalve Mya truncata , and arcticExpand

Polar cod (Boreogadus saida) and capelin (Mallotus villosus) as key species in marine food webs of the Arctic and the Barents Sea
Abstract Polar cod and capelin are key species in Arctic and sub-Arctic marine food webs, respectively, and the objective of this study is to compare and contrast the two species. Their distributionsExpand

Food Web Magnification of Persistent Organic Pollutants in Poikilotherms and Homeotherms from the Barents Sea
Food web magnification of persistent organic pollutants (POPs) was determined for the Barents Sea food web using δ15N as a continuous variable for assessing trophic levels (TL). The food webExpand

Biomagnification of mercury in selected species from an Arctic marine food web in Svalbard.
Concentrations and biomagnification of total mercury (TotHg) and methyl mercury (MeHg) were studied in selected species from the pelagic food web in Kongsfjorden, Svalbard. Twelve species ofExpand

Trophic relationships and pelagic-benthic coupling during summer in the Barents Sea Marginal Ice Zone, revealed by stable carbon and nitrogen isotope measurements
Food web structure and pathways from primary production were studied in pelagic, sympagic (ice-associated) and benthic communities during summer in a seasonally ice covered region of the northernExpand

Bioaccumulation of per- and polyfluorinated alkyl substances (PFAS) in selected species from the Barents Sea food web.
The present study reports concentrations and biomagnification potential of per- and polyfluorinated alkyl substances (PFAS) in species from the Barents Sea food web. The examined species included seaExpand
