Ice-covered seas does not need to be cold

Much ice on the sea surface does not mean that the sea is cold. North of Svalbard we saw ice and melt water on the sea surface, while we measured seven degrees at 30 meters depth. During the first cruise in the project SI_Arctic, cod was the fish species caught the most places. Between the ice-free areas in the Fram Strait and the ice covered areas north of Svalbard there were clear differences in species and quantity of plankton, fish and marine mammals.

Biological postcards letter from Finnmark and the Barents Sea

This newsletter has been written by all the biologists onboard the G.O.Sars at the last biogy and geology cruise in 2014. Each biologist has picked her favourite photo from the work on this cruise, and they have written a story for that picture.  There are many different voices here, this reflects both the diversity we see in the benthic communities – and the diversity among the biologists.

In focus: European lobster

The European lobster has been found from the Mediterranean Sea to Northern Norway and west to the Shetland Island and western Ireland. It is usually found in shallow waters less than 40 m deep, where it is night active and shelter in burrows during daytime.

Their preferred habitat is moderately exposed areas with a complex bottom substrate of a mixture of sand and rocks. The lobster has a wide diet, hunting live prey and scavenging on dead organisms.
