Marine researchers find a dramatic ecosystem shift in Russian Arctic waters

Species that previously were non-existent in Russia's remote and icy Arctic waters are now found in big numbers.

The researchers that were on board the «Professor Levanidov» on the recent trans-arctic expedition have remarkable stories to tell.

Among the discoveries made was halibut on more than 200 meter depths in the Laptev Sea and snow crab in the northeastern parts of the East Siberian Sea and Chukchi Sea. They also found Alaska pollock in the waters of the Chukchi Sea and large numbers of big and mature polar cod in the Kara Sea.

The latter fish is more or less eradicated from the Barents Sea where other southern species have taken its place.
