Counter-clockwise rotation of the sea surface high observed near the west coast of Norway. Archival data radar altimeters on ERS-1, ERS-2 and Envisat satellites show undulate around the center of the Lofoten Basin.
Pool Lofotenskihe Islands topographic depression depth of about 3500 m in the Norwegian Sea. He is known to be the major reservoir of heat to the northern seas (Greenland, Iceland and the Norwegian Sea) where there is a strong interaction between the ocean and the atmosphere. (Credit: D.

Pool Lofoten Islands in the Norwegian Sea has played an important role in maintaining the global ocean circulation. He is a transit area for warm and salty Atlantic water on the way to the Arctic Ocean. Here, the incoming Atlantic waters give off heat and mix with the atmosphere of the surrounding water. This leads to the fact that water becomes dense and sinks, forming the «deep water» in the surrounding area — is another important step in ocean circulation.
Using satellite data, scientists have observed topographic waves in the Lofoten Basin, which are largely responsible for raising the height of the sea surface and the variability in the area. Waves of about 10 cm in height covered in an anti-clockwise direction. Most of the observed waves have a length of about 500 km, and are moved to a distance of two to eight miles a day.
Waves can lead to various perturbations, such as wind or tortuosity Norwegian Atlantic Current. It is likely that they can increase the mixing of water masses, and even affect the low-frequency variability of local biological processes …
