Greenland Sea - Geography and Geology

Geography and Geology

The Greenland Sea is bounded to the west by the island of Greenland, and to the south by the Denmark Strait and Iceland. To the southeast, behind the Jan Mayen island (Norway) lies the vast expanse of the Norwegian Sea, of which Greenland Sea may be considered an extension. Across the Fram Strait to the northeast, the sea is delimited by the Svalbard archipelago (Norway).

The bottom of the Greenland Sea is a depression bounded to the south by the underwater Greenland-Iceland ridge and to the east by the Mohns Ridge and Knipovich Ridge (parts of the Mid-Atlantic Ridge). To the west, the bottom rises first slowly, but then rapidly toward the wide Greenland coastal strip. Silts fill the submarine hollows and gorges; silty sands, gravel, boulders, and other products of erosion coat the shelves and ridges.

Although the deepest point inside of the sea is 4846 meters, depths down to 5570 meters have been measured in the Molloy Deep of the Fram Strait which connects the sea to the Arctic Ocean on the north.

Major islands of the Greenland Sea include Svalbard archipelago, Edvards, Eila, Godfred Hansens, Île-de-France, Jan Mayen Lynns, Norske and Schnauders. Of those, only the Svalbard islands are inhabited, and Jan Mayen has only temporal military staff. After the League of Nations gave Norway jurisdiction over the island, in 1921 Norway opened the first meteorological station there, which was a subject of contention between Germany and United Kingdom during World War II. Several radio and meteorological stations operate on the island nowadays.
