 The North Atlantic Drift Current
The N. Atlantic drift is the broad, northward flow of surface waters that replaces the sinking waters in the N. Atlantic polar seas.
Because of the rapid advection of the North Atlantic gyre, the temperature of the surface waters of the NADC almost always exceeds that of both surrounding waters and the overlying atmosphere (Rossby, 1996).
According to Krauss and Käse (1984), the North Atlantic Current, and not interference with the Mid-Atlantic Ridge, is the main source of eddy energy in the North Atlantic.

North of the Gulf Stream these rings tend to be at the smaller end of this range and they rotate clockwise and enclose warm water.
The North Atlantic pumps, and the Gulf Stream, are parts of the global ocean circulation system (dubbed the “conveyer belt” by oceanographers).
At North Atlantic pumps, warm surface water arriving from the south is cooled by sub-Arctic air and sinks, so driving the pumps.

 Barents Sea - Wikipedia, the free encyclopedia
It is a rather deep shelf sea (average depth 230 m), bordered by the shelf edge towards the Norwegian Sea in the west, the island of Svalbard (Norway) in the north-west, and the islands of Franz Josef Land and Novaya Zemlya (Russia) in the north-east and east.
There are three main types of water masses 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, and warm, but not very salty coastal water (temperature >3°C, salinity<34,7).
In the western parts of the sea (close to Bjørnøya), this front is determined by the bottom topography and is therefore relatively sharp and stable from year to year, while in the east (towards Novaya Zemlya), its can be quite diffuse and its position varies a lot between years.

 Gulf Stream
The North Atlantic Drift forms the extension to the Gulf Stream which flows past the south coast of Labrador towards the west coast of Europe.
In the North Atlantic, the heavy salt water becomes cold enough to sink, forming a deep ocean current called the North Atlantic Deep Water (NADW).
This slowed and diverted the course of the Gulf Stream to such as extent that the regional climate of the Northeast Atlantic became considerably cooler.

 Gulf Stream - Wikipedia, the free encyclopedia
Its extension toward Europe, called the North Atlantic drift, makes West-European countries considerably warmer than they would be otherwise.
As it travels north, some of the warm water transported by the Gulf Stream evaporates.
This increases the salinity of the water in the stream, and in the North Atlantic Ocean the water is so cold and dense with salt that it begins to sink.

 North Atlantic current - Wikipedia, the free encyclopedia
The North Atlantic current is a powerful warm ocean current that continues the Gulf Stream northeast.
One branch (the Canary current) goes south while the other continues north along the coast of northwestern Europe where it has a considerable warming influence on the climate.
Climate change, especially global warming, may have a significant effect on the current.

If this current is sufficiently disrupted it could cause the mean temperature for Western Europe to fall by 5° Celsius.
It is thought this may be caused by global warming leading to increased rainfall and melting of the Arctic pack ice.
As the current is powered both by water temperature and salinity in the North Atlantic, such an increase of fresh water may pose a risk of disruption.

 CRU Information Sheet no. 7: Thermohaline circulation
It is warmer in the North Atlantic because warm water is brought by the thermohaline circulation from the tropical and South Atlantic.
Increased rainfall and warming over the North Atlantic are both expected as a result of increased greenhouse gas concentrations, and so it can be argued that global warming may cause a rapid collapse of the thermohaline circulation.
The northern North Atlantic and NW Europe have annual temperatures that are about 9 degrees C above the average for their latitude, but this cannot all be attributed to the THC, since the wind driven ocean circulation helps to transport heat to these regions too.

 Climate Control Requires a Dam at the Strait of Gibraltar
Although mixing with North Atlantic Drift water doubtless occurs, Reid's [1979] temperature and salinity data suggest that much of the cold outflow water passes on into the Nordic Seas.
The diversion of North Atlantic Drift water as a function of the Mediterranean outflow is difficult to measure accurately because of the complex and fluctuating currents within the northern gyre.
Probably not, because the redirection of warm North Atlantic Drift into the Nordic Seas would duplicate the strong meridional North Atlantic circulation of 8000 years ago, when the outflow was smaller, the Labrador Sea was cold, and deglaciation was rapidly removing the Laurentide Ice Sheet.
