The Ross Sea is a deep bay of the Southern Ocean in Antarctica, between Victoria Land and Marie Byrd Land. It derives its name from the British explorer James Ross who visited this area in 1841. To the west of the sea lies Ross Island and to the east Roosevelt Island, while the southernmost part is covered by the Ross Ice Shelf, and is about 200 miles (320 km) from the South Pole.
The circulation of the Ross Sea is dominated by a wind-driven ocean gyre and the flow is strongly influenced by three submarine ridges that run from southwest to northeast. The circumpolar deep water current is a relatively warm, salty and nutrient-rich water mass that flows onto the continental shelf at certain locations. The Ross Sea is covered with ice for most of the year.
The nutrient-laden water supports an abundance of plankton and this encourages a rich marine fauna. At least ten mammal species, six bird species and 95 fish species are found here, as well as many invertebrates, and the sea remains relatively unaffected by human activities.
The Ross Sea was discovered by James Ross in 1841. In the west of the Ross Sea is Ross Island with the Mt. Erebus volcano, in the east Roosevelt Island. The southern part is covered by the Ross Ice Shelf. Roald Amundsen started his South Pole expedition in 1911 from the Bay of Whales, which was located at the shelf. In the west of the Ross sea, McMurdo Sound is a port which is usually free of ice during the summer. The southernmost part of the Ross Sea is Gould Coast, which is approximately two hundred miles from the Geographic South Pole.
The Ross Ice Shelf is the largest ice shelf of Antarctica (an area of roughly 487,000 square kilometres and about 800 kilometres across: about the size of France). It is several hundred metres thick. The nearly vertical ice front to the open sea is more than 600 kilometres long, and between 15 and 50 metres high above the water surface. Ninety percent of the floating ice, however, is below the water surface.
The ice shelf is named after Captain Sir James Clark Ross, who discovered it on 28 January 1841 (source: Wikipedia).
