In this study we investigate both historical and potential future changes in the spatial distribution of spawning habitats for Northeast Arctic cod (NEA cod) based on a literature study on spawning habitats and different physical factors from a downs

Predator-prey spatial interactions are essential to understand ecosystem processes like predation rates and trophic interaction strength. In marine systems, such spatial interactions are highly dynamic and difficult to observe, as predators, prey and

Spatial overlap between predator and prey is a prerequisite for predation, but the degree of overlap is not necessarily proportional to prey consumption. This is because many of the behavioural processes that precede ingestion are non-linear and depe

Seasonal variation in feeding and growth of 3- to 9-year-old Atlantic cod (Gadus morhua) was studied using data from joint Norwegian–Russian surveys in January–March (winter survey) and September–August (ecosystem survey) in the Barents Sea. Th

Shifts in the geographic distribution of fish influence coverage of a stock in scientific surveys, and variation in climate and abundance of the stock are potential factors influencing this. During the winter survey for demersal fish in the Barents S

Dispersal of 137 Cs from the nuclear submarine wrecks Komsomolets and K-159 , which are resting on the seabed in the Norwegian and Barents Seas, respectively, is simulated using realistic rates and hypothetical scenarios. Furthermore, spatiotemporal
