Formation of heavy bottom water in the Barents Sea

Formation of heavy bottom water through rejection of brine during ide freezing is a regular phenomenon in the Barents Sea, particular on the Novaya Zemlya shelf, but also observed in other shallow localities of the sea. Water with temperature around -1°C and salinity above 34.95 is found moving eastwards on the southern side of the Novaya Zemlya-Franz Josef Land Channel which communicates with the Polar Sea. The relative high salinity is a result of admixture from heavy water formed during the freezing process

Norwegian blue whiting investigation in April/May 1980.

An acoustic survey on the blue whiting stock was conducted from 8 April to 14 May 1980. The area west of the British Isles was covered twice and then the area around the Farces and further up to Shetland and the Norwegian coast covered once. Blue whiting was recorded in the area around the Faroes and along the slope continously south to the Porcupinebank, with densest concentrations found off the Hebrides. The hydrographical situation is presented and also the age and length compositions, maturity conditions and the length-weight relationships of the blue whiting in the area. Higher contributions of young fish were found to represent the blue whiting stock in the spawning area, than observed in recent years. Acoustic abundance estimate gave a figure of 5.4 mill.tonnes of blue whiting, which is 2,5 mill.tonnes lesser than the recalculated figure of 1979
