The Weddell Sea is part of the Southern Ocean and contains the Weddell Gyre. Its land boundaries are defined by the bay formed from the coasts of Coats Land and the Antarctic Peninsula. The easternmost point is Cape Norvegia at Princess Martha Coast, Queen Maud Land. To the east of Cape Norvegia is the King Haakon VII Sea. Much of the southern part of the sea is covered by a permanent, massive ice shelf field, the Filchner-Ronne Ice Shelf.
The Filchner-Ronne Ice Shelf, also known as Ronne-Filchner Ice Shelf, is an Antarctic ice shelf bordering the Weddell Sea.
Elephant Island is an ice-covered, mountainous island off the coast of Antarctica in the outer reaches of the South Shetland Islands, in the Southern Ocean. The island is situated 245 kilometres north-northeast of the tip of the Antarctic Peninsula, 1,253 kilometres west-southwest of South Georgia, 935 kilometres south of the Falkland Islands, and 885 kilometres southeast of Cape Horn. It is within the Antarctic claims of Argentina, Chile and the United Kingdom.
The Transantarctic Mountains comprise a mountain range of uplifted rock in Antarctica which extend, with some interruptions, across the continent from Cape Adare in northern Victoria Land to Coats Land. These mountains divide East Antarctica and West Antarctica. They include a number of separately named mountain groups, which are often again subdivided into smaller ranges.
The Recovery Glacier is a glacier flowing west along the southern side of the Shackleton Range in Antarctica. First seen from the air and examined from the ground by the Commonwealth Trans-Antarctic Expedition in 1957, it was so named because of the recovery of the expedition's vehicles which repeatedly broke into bridged crevasses on this glacier during the early stages of the crossing of Antarctica. It is at least 100 km (60 mi) long and 64 km (40 mi) wide at its mouth.
The Queen Alexandra Range is a major mountain range of the Transantarctic Mountains System, located in the Ross Dependency region of Antarctica.
The Brunt Ice Shelf borders the Antarctic coast of Coats Land between Dawson-Lambton Glacier and Stancomb-Wills Glacier Tongue. It was named by the UK Antarctic Place-names Committee after David Brunt, British meteorologist, Physical Secretary of the Royal Society, 1948–57, who was responsible for the initiation of the Royal Society Expedition to this ice shelf in 1955.
Hayes Glacier in Antarctica enters the southeast part of the Weddell Sea about 17 miles (27 km) west-southwest of Dawson-Lambton Glacier. It was discovered in the course of a U.S. Navy LC-130 plane flight over the Caird Coast on November 5, 1967, and was plotted by the United States Geological Survey from photographs obtained at that time. It was named by the Advisory Committee on Antarctic Names for Lieutenant Commander Winston R. Hayes, U.S. Navy Reserve, the pilot on that flight.
Fortuna Glacier is a tidewater glacier at the mouth of Cumberland Bay on the island of South Georgia. It flows in a northeast direction to its terminus just west of Cape Best, with an eastern distributary almost reaching the west side of Fortuna Bay, on the north coast of South Georgia. It was named in about 1912, presumably after the whale catcher Fortuna, and is notable for two major events in the 20th Century.
Shackleton Ice Shelf is an extensive ice shelf fronting the coast of East Antarctica from 95° E to 105° E. It extends for an along-shore distance of about 384 kilometres (239 mi), projecting seaward about 145 kilometres (90 mi) in the western portion and 64 kilometres (40 mi) in the east. It occupies an area of 33,820 square kilometres (13,058 sq mi). It is part of Mawson Sea and separates the Queen Mary Coast to the west from the Knox Coast of Wilkes Land to the east.
The Imperial Trans-Antarctic expedition of 1914–1917 is considered to be the last major expedition of the Heroic Age of Antarctic Exploration. Conceived by Sir Ernest Shackleton, the expedition was an attempt to make the first land crossing of the Antarctic continent. After Roald Amundsen's South Pole expedition in 1911, this crossing remained, in Shackleton's words, the "one great main object of Antarctic journeyings". Shackleton's expedition failed to accomplish this objective, but became recognized instead as an epic feat of endurance.
Mertz Glacier is a heavily crevassed glacier in George V Coast of East Antarctica. It is the source of a glacial prominence that historically has extended northward into the Southern Ocean, the Mertz Glacial Tongue. It is named in honor of the Swiss explorer Xavier Mertz.
The Stancomb-Wills Glacier is a large glacier that debouches into the eastern Weddell Sea southward of Lyddan Island. The glacier was discovered in the course of the U.S. Navy LC-130 plane flight over the coast on November 5, 1967, and was plotted by the United States Geological Survey (USGS) from photographs obtained at that time. The name was applied by the Advisory Committee on Antarctic Names (US-ACAN) in 1969.
The Scottish National Antarctic Expedition (SNAE), 1902–1904, was organised and led by William Speirs Bruce, a natural scientist and former medical student from the University of Edinburgh. Although overshadowed in terms of prestige by Robert Falcon Scott's concurrent Discovery Expedition, the SNAE completed a full programme of exploration and scientific work. Its achievements included the establishment of a staffed meteorological station, the first in Antarctic territory, and the discovery of new land to the east of the Weddell Sea. Its large collection of biological and geological specimens, together with those from Bruce's earlier travels, led to the establishment of the Scottish Oceanographical Laboratory in 1906.
The Second German Antarctic Expedition of 1911–1913 was led by Wilhelm Filchner in the exploration ship Deutschland. Its principal objective was to determine whether the Antarctic continent comprised a single landmass rather than separated elements, and in particular whether the Weddell Sea and Ross Sea were connected by a strait. In addition, an extensive programme of scientific research was undertaken. The expedition failed to establish a land base, and the ship became beset in the Weddell Sea ice, drifting north for eight months before reaching open water. The expedition was marred by considerable disagreement and animosity among its participants, and broke up in disarray.
The Erebus Ice Tongue is a mountain outlet glacier and the seaward extension of Erebus Glacier from Ross Island. It projects 11 kilometres (6.8 mi) into McMurdo Sound from the Ross Island coastline near Cape Evans, Antarctica. The glacier tongue varies in thickness from 50 metres (160 ft) at the snout to 300 metres (980 ft) at the point where it is grounded on the shoreline. Explorers from Robert F. Scott's Discovery Expedition (1901–1904) named and charted the ice tongue.
The McDonald Ice Rumples constitute an ice rise in the Brunt Ice Shelf bordering the Weddell Sea in Antarctica, covering an area of 3 by 2 nautical miles.
Farthest South refers to the most southerly latitude reached by explorers before the first successful expedition to the South Pole in 1911. Significant steps on the road to the pole were the discovery of lands south of Cape Horn in 1619, Captain James Cook's crossing of the Antarctic Circle in 1773, and the earliest confirmed sightings of the Antarctic mainland in 1820. From the late 19th century onward, the quest for Farthest South latitudes became in effect a race to reach the pole, which culminated in Roald Amundsen's success in December 1911.
The Imperial Trans-Antarctic Expedition was an attempt to cross the Antarctic continent led by Ernest Shackleton. The personnel were divided into two groups: the Weddell Sea party consisting of the men who would attempt the crossing and their support, and the Ross Sea party whose job it was to lay stores on the far side of the Pole for the members of the Weddell Sea party who would make the crossing. Both arms of the expedition had a final complement of 28 men. The Weddell Sea party's ship Endurance was crushed in pack ice and the crossing attempt was never made. All the Weddell Sea party were rescued, but several members of the Ross Sea party perished after their support ship Aurora broke free from its mooring post and drifted away, leaving the shore party stranded.
