    The ocean current system off Southern Greenland is a key component of the Earth’s climate system due to its role in the regulation of the global thermohaline circulation. A combination of historic and new observational data, supported by modelling simulations, has revealed great complexity in both the surface and deep currents of the area. km broad. The physical oceanographic conditions in west Greenland waters are controlled by the large-scale circulation in the North Atlantic: a branch of the warm North Atlantic current circles anti-clockwise in the Irminger Sea off southeast Greenland to join the cold East Greenland Current and around Cape Farewell to form the north-setting.

    shelf along both the east Greenland and east- ern Canadian margins, and its extent and dura- tion is fundamental in determining aspects of the near-shore terrestrial climate (Fribriksson ). Sea-ice forms easily on low-salinity Polar Water, which comes from the Arctic Ocean and contributes to the East Greenland Current. This fresh water has three sources: Pacific water (relatively fresh cf. Atlantic water), river runoff, and sea ice meltwater. To determine the relative amounts of the three sources of fresh water, in May we collected water samples across the East Greenland Current in sections from degrees N to the Irminger Sea south of Denmark Strait.

The East Greenland Current (EGC) is a cold, low salinity current that extends from Fram Strait (~80N) to Cape Farewell (~60N). The current is located off the eastern coast of Greenland along the Greenland continental margin. The current cuts through the Nordic Seas (the Greenland and Norwegian Seas) and through the Denmark Strait.

The current is of major importance because it directly connects. Title. An investigation of the waters of the East Greenland current / Related Titles.

ABSTRACT The East Greenland Current (EGC) in Fram Strait is examined in summer, based on the hydrographic data from the MIZEX 84 experiment, and its dynamics is further analyzed using a simple analytical model.

The Greenland Sea is a body of water that borders Greenland to the west, the Svalbard archipelago to the east, Fram Strait and the Arctic Ocean to the north, and the Norwegian Sea and Iceland to the south.

The Greenland Sea is often defined as part of the Arctic Ocean, sometimes as part of the Atlantic Ocean. However, definitions of the Arctic Ocean and its seas tend to be imprecise or arbitrary.

Spitsbergen Current (WSC) transports warm (C 88C) Atlantic Water (AW) into the Arctic Ocean, while the East Greenland Current (EGC) carries cold (ca. C 08C) Polar Water (PW) in the upper m towards the south in the western part of the strait.

In southwest Greenland two water masses are predominant: the cold, low salinity, coastal water of the East Greenland Current; and the warmer, higher salinity, Atlantic water (Myers et al., East Greenland to join the cold East Greenland Current and around Cape Farewell to form the north-setting West Greenland Current.

Under the influence of this relatively warm current, the West Greenland marine ecosystem is Sub-Arctic. Sea ice in winter usually extends no further south than about 66 N. The transport of heat salt and nutrients, as.

It lies south of the Arctic Basin proper and borders Greenland (west), Svalbard (east), the main Arctic Ocean (north), and the Norwegian Sea and Iceland (south).

It is hypothesised that strands of overflow water follow different depth. The marine environment in Greenland is vast and diverse, stretching from the high Arctic Polar Basin at 84°N to the western North Atlantic at 58°N where relatively warm water from the Irminger current has a profound and’s marine environment includes three large marine ecosystems (LMEs) (Skjoldal & Sherman, ), and therefore, assessing the status of the marine environment in.
