1 Location

The Norwegian Sea (Norwegian: Norskehavet) is part of the North Atlantic Ocean northwest of Norway, located between the North Sea (i.e. north of Scotland) and the Greenland Sea.

It adjoins the Iceland Sea to the west and the Barents Sea to the northeast. In the southwest, it is separated from the Atlantic Ocean by a submarine ridge running between Iceland and the Færøerne Islands. To the North, the Jan Mayen Ridge separates it from the Arctic Ocean.

The Norwegian Sea, the Greenland Sea and the Icelandic Sea are sometimes collectively referred to as the Nordic Seas.

3 Currents

In the Norwegian Sea and Greenland Sea, surface water descends two to three kilometres down to the bottom of the ocean, forming cold, oxygen-rich groundwater.

As a result, there is a warm surface current and a cold depth current running along the west coast of Norway.

The so-called East Iceland Current transports cold water south from the Norwegian Sea towards Iceland and then east, along the Arctic Circle. In the Norwegian Atlantic Current, a branch of the Gulf StreamThe Gulf Stream also known as the North Atlantic Drift is a powerful warm, swift Atlantic ocean current that flows along the coast of the Eastern United States and makes Ireland, Great Britain, and the Scandinavian countries warmer than they would be othe carries warm water masses northward and contributes to the mild and moist climate in Norway.

The Norwegian Sea is the source of much of the North Atlantic Deep WaterThe North Atlantic Deep Water is a water mass in the Atlantic Ocean. It is largely formed in the Labrador Sea where the North Atlantic drift ends in the northeast Atlantic (northeast of Iceland) by the sinking of dense overflow water from the Norwegian Se.

Nowadays, shifts and fluctuations in these currents are closely monitored, as they are thought to be indicators for an ongoing climate changeThe term climate change is used to refer to changes in the Earth's climate. In the most general sense, it can be taken to mean changes over all timescales and in all of the components of climate, including precipitation and clouds as well as temperature..

4 Conditions

The Norwegian Sea remains generally ice-free due to the warm and saline Norwegian Atlantic Current.

It provides rich fishing grounds, with catches mostly consisting of herrings, sardines and anchovies.

Large-scaled oil and gas production in the Norwegian Sea started in 1993.

In recent news, the Norwegian Sea was proposed as a prototype storage site for the greenhouse gasGreenhouse gases are gaseous components of the atmosphere that contribute to the greenhouse effect. The major natural greenhouse gases are water vapor, which causes about 60% of the greenhouse effect on Earth, carbon dioxide (about 26%), and ozone. Minor carbon dioxideCarbon dioxide is an atmospheric gas composed of one carbon and two oxygen atoms. One of the best known of chemical compounds, it is frequently called by its formula: :CO (pronunciation: "see oh two") Carbon dioxide results from the combustion of organic (see CO2 sinkA carbon dioxide CO) sink is the opposite of a carbon source. The main sinks are the oceans and growing vegetation. The concept has become widely known through the Kyoto protocol. The idea is that growing vegetation absorbs carbon dioxide, so that countri).

Norwegian Sea is also the name of a cruise liner registered with the Bahamas. The ship is 213 m long, has 9 guest decks, a GRT of 42,000 tons and a capacity of about 1,500 passengers. It was formerly named Seaward and launched in 1988.
