The Barents Sea is a part of the Arctic Ocean, lies to the north of Norway and Russia.
It is quite deep shelf sea, with average depth of 760 feet (230 m) and maximum depth of 1,480 feet (450 m) , surrounded by the shelf edge towards the Norwegian Sea in the west, the island of Svalbard (Norway) in the northwest, and the islands of Franz Josef Land and Novaya Zemlya (Russia) in the northeast and east. Novaya Zemlya separates the Kara Sea and the Barents Sea.
Naming: The Sea is known as Murman Sea in the middle Ages, the current name has come from the Dutch navigator Willem Barentsz.
Resources: Fossil fuel energy is the significant resources exist in the Barents Sea region.
The southern part of the Barents Sea, including the ports of Murmansk (Russia) and Vardų (Norway) remains ice-free year round due to the warm North Atlantic drift. In September, the entire Barents Sea is more or less ice-free.
Three main types of water heaps in the Barents Sea:
. Warm, salty Atlantic water (temperature >3°C, salinity>35) from the North Atlantic drift,
. Cold Arctic water (temperature <0"C, salinity<35) from the north,
. Warm, but not very salty coastal water (temperature >3°C, salinity<34.7).
Because of the North Atlantic drift, the Barents Sea has a rich biological production such as phytoplankton, zooplankton (Calanus finmarchicus, Calanus glacialis, Calanus hyperboreus, Oithona spp., and krill) etc.
