Calved from the Ross Ice Shelf of Antarctica in March 2000, Iceberg B-15 broke up into smaller icebergs, the largest of which was named Iceberg B-15-A. In 2003, B-15A drifted away from Ross Island into the Ross Sea and headed north, eventually breaking up into several smaller icebergs in October 2005. [2]
Little America was a series of Antarctic exploration bases from 1929 to 1958, located on the Ross Ice Shelf, south of the Bay of Whales.The were built on ice that is moving very slowly, the relative location on the ice sheet, has moved and eventually breaks off into an iceberg.
After their loss the reduced buttressing of feeder glaciers has allowed the expected speed-up of inland ice masses after shelf ice break-up. [51] The Ross Ice Shelf is the largest ice shelf of Antarctica (an area of roughly 487,000 square kilometres (188,000 sq mi) and about 800 kilometres (500 mi) across: about the size of France). [52]
The Ross Sea was discovered by the Ross expedition in 1841. In the west of the Ross Sea is Ross Island with the Mt. Erebus volcano; in the east is Roosevelt Island. The southern part is covered by the Ross Ice Shelf. [5] Roald Amundsen started his South Pole expedition in 1911 from the Bay of Whales, which was located at the shelf.
Separating the two subcontinents is a lower elevation topographic region occupied by the Ross Ice Shelf and the Ross Sea. This region is referred to as the Ross Embayment. The embayment comprises an area of approximately 1,137,000 square kilometres (439,000 sq mi).
To the south, the sound is bounded by the Ross Ice Shelf cavity, to the west lies the Royal Society Range, and to the east is Ross Island. McMurdo Sound is separated from the McMurdo Ice Shelf (part of the Ross Ice Shelf) by the Haskell Strait. Winter Quarters Bay lies at the south end of the Sound and is the southernmost port on Earth.
