Murmansk, the Maritime Port. The Kara Sea, the Barents Sea, and other northern seas: icebreakers, fishing trawlers at sea, fish catching. The Arctic coast. One of the reserves: a bird market where reserve workers band birds and collect eiderdown. A meteorological station. Winterers, families of winterers on one of the islands. A woman feeds bear cubs with condensed milk. A polar bear jumps from ice floe to ice floe.
