Mechanisms initiating fluid migration at Snøhvit and Albatross fields, Barents Sea

Barents Sea multidecadal variability

[1] We present area-averaged time series of temperature for the 100–150 m depth layer of the Barents Sea from 1900 through 2006. This record is dominated by multidecadal variability on the order of 4 C which is correlated with the Atlantic Multidecadal Oscillation Index. Citation: Levitus, S., G. Matishov, D. Seidov, and I.

The Barents Sea

Fisheries in the North Atlantic, southeast Atlantic, and eastern central Atlantic reached their maximum production levels one or two decades ago and are now showing a declining trend in total catches (1). The declining catches are consistent with observations that these areas have the highest incidence of overexploited stocks, depleted stocks or slowly recovering stocks that have been depleted ...

Primary Producers of the Barents Sea

Swimming energetics of the Barents Sea capelin (Mallotus villosus) during the spawning migration period

The Barents Sea capelin, a schooling species, undertakes extensive migrations against the predominating current north of Norway to its spawning grounds along the Norwegian and Russian coasts. Low swimming costs (i.e. high efficiency) at cruising speeds would be advantageous for capelin, enabling allocation of more energy to reproduction. A high oxygen uptake capacity may however also be benefic...

Feeding and Food Consumption by the Barents Sea Skates

Stomach content data were used to study spatial, seasonal and interannual dynamics of feeding of the thorny skate Raja radiata. Data on food composition for other Barents Sea skates ( Northern skate – R. hyperborea, Round skate – R. fyllae, Blue skate – R. batis, Spinytail skateR. spinicauda, Long-nosed skate – R. oxyrhynchus and Sail ray R. lintea) are presented. The diet of thorny skate of di...
