Current measurements in the northeastern Barents Sea
The Institute of Marine Research (IMR) in cooperation with Knipowich Polar Reseach Institute of Marine Fisheries and Oceanography (PINRO), Murmansk, started in autumn 1991 a current measurement program in the strait between Novaya Zemlya and Frans Josef Land. The objectives of the project were: - to...

Low pressure seems to create a strong circulation in the Barents Sea, while high pressure periods seems to decrease the circulation.
