The Filchner-Ronne Ice Shelf, also known as Ronne-Filchner Ice Shelf, is an Antarctic ice shelf bordering the Weddell Sea.
Jackie Ronne was an American explorer of Antarctica and the first woman in the world to be a working member of an Antarctic expedition (1947-8). She is also the namesake of the Ronne Ice Shelf.
Alexander Island, which is also known as Alexander I Island, Alexander I Land, Alexander Land, Alexander I Archipelago, and Zemlja Alexandra I, is the largest island of Antarctica. It lies in the Bellingshausen Sea west of Palmer Land, Antarctic Peninsula from which it is separated by Marguerite Bay and George VI Sound. George VI Ice Shelf entirely fills George VI Sound and connects Alexander Island to Palmer Land. The island partly surrounds Wilkins Sound, which lies to its west. Alexander Island is about 390 kilometres (240 mi) long in a north-south direction, 80 kilometres (50 mi) wide in the north, and 240 kilometres (150 mi) wide in the south. Alexander Island is the second largest uninhabited island in the world, after Devon Island.
Spaatz Island is a large ice-covered island of Antarctica. It lies south west of Alexander Island and west of the base of the Antarctic Peninsula, close to the coast of Palmer Land, 48 km (30 mi) east of Smyley Island. It is 80 km (50 mi) long and 40 km (25 mi) wide, and covers an area of around 4,100 km2 (1,583 sq mi).
Mount Vang is an isolated mountain standing southward of George VI Sound and 80 miles east-southeast of Eklund Islands in southern Palmer Land. It was discovered by Finn Ronne and Carl Eklund of the US Antarctic Service (USAS), 1939–41, during their sledge journey through George VI Sound, and resighted from the air on a flight of December 3, 1947 by the Ronne Antarctic Research Expedition (RARE) under Ronne.
The Douglas Range is a sharp-crested range, with peaks rising to 3,000 metres, extending 120 km in a northwest-southeast direction from Mount Nicholas to Mount Edred and forming a steep east escarpment of Alexander Island within the British Antarctic Territory, overlooking the north part of George VI Sound.
Ronne Entrance is a broad southwest entrance of the George VI Sound where it opens from the southeast portion of the Bellingshausen Sea at the southwest side of Alexander Island, Antarctica. The south side of the Monteverdi Peninsula occupies the north portion of the Ronne Entrance while Ellsworth Land occupies the southern portion of the entrance. The entrance receives much ice throughout the whole year mainly because the entrance protrudes eastward into the adjacent George VI Sound and the George VI Ice Shelf from the southwest section, the Ronne Entrance is also prone to ice flow from the Bach Ice Shelf as well as receiving ice from the Wilkins Ice Shelf. There are a few islands situated within the Ronne Entrance, mainly in the southwest area. Some of these islands include the Eklund Islands, DeAtley Island, Spaatz Island, Case Island and Smyley Island. It was discovered on a sledge journey through the sound in December 1940 by U.S. Polar explorer Finn Ronne and Carl Eklund of the US Antarctic Service (USAS), 1939–41, and named "Ronne Bay". Finn Ronne covered more miles by ski and sled dog than any other explorer in history and mapped the last unknown coastline on earth on his Ronne Antarctic Research Expedition in 1947.
The Ronne Antarctic Research Expedition (RARE) was an expedition from 1947–1948 which researched the area surrounding the head of the Weddell Sea in Antarctica.
Mount Umbriel is a peak, rising to about 1,500 m, overlooking the head of Venus Glacier on the east coast of Alexander Island, Antarctica, with the east face of the mountain overlooking the George VI Ice Shelf that occupies George VI Sound. The mountain was first mapped by Searle of the Falkland Islands Dependencies Survey in 1960, from air photos taken by the Ronne Antarctic Research Expedition in 1947-48. Named by the United Kingdom Antarctic Place-Names Committee from association with nearby Uranus Glacier, Umbriel being one of the satellites of the planet Uranus, the seventh planet of the Solar System.
Uranus Glacier is a glacier on the east coast of Alexander Island, Antarctica, 30 kilometres long and 10 km (6 mi) wide at its mouth, flowing east into George VI Sound immediately south of Fossil Bluff. Along the south face of the glacier is an east–west escarpment called Kuiper Scarp.
The George VI Ice Shelf is an extensive ice shelf that occupies George VI Sound which separates Alexander Island from Palmer Land in Antarctica. The ice shelf extends from Ronne Entrance, at the southwest end of the sound, to Niznik Island, about 30 nautical miles (56 km) south of the north entrance between Cape Brown and Cape Jeremy. It was named by the UK Antarctic Place-Names Committee in association with George VI Sound.
The Eklund Islands are a group of islands which rise through the ice near the southwest end of George VI Sound towards the south of the Antarctic Peninsula.
Neptune Glacier is a glacier on the east coast of Alexander Island, Antarctica, 12 nautical miles (22 km) long and 4 nautical miles (7 km) wide, flowing east into George VI Sound and the George VI Ice Shelf to the south of Triton Point. Although Neptune Glacier is not located within the mountain range Planet Heights, the glaciers name derives from the mountain range along with many other nearby glaciers named after planets of the Solar System. There are also other nearby landforms named in association with these glaciers. The glacier was first sighted from the air by Lincoln Ellsworth on November 23, 1935, and roughly mapped from photos obtained on that flight by W.L.G. Joerg. The mouth of the glacier was positioned in 1936 by the British Graham Land Expedition (BGLE). Named by the United Kingdom Antarctic Place-Names Committee (UK-APC) for the planet Neptune following a Falkland Islands Dependencies Survey (FIDS) survey in 1949. The head of the glacier was mapped from air photos taken by the Ronne Antarctic Research Expedition (RARE), 1947–48, by Searle of the FIDS in 1960.
Eros Glacier is a glacier on the east coast of Alexander Island, Antarctica, 7 nautical miles (13 km) long and 2 nautical miles (4 km) wide at its mouth, flowing southeast from the Planet Heights into George VI Sound immediately north of Fossil Bluff. It was probably first seen on November 23, 1935, by Lincoln Ellsworth, who flew directly over the glacier and obtained photos of features north and south of it. The mouth of the glacier was observed and positioned by the British Graham Land Expedition in 1936 and the Falkland Islands Dependencies Survey (FIDS) in 1948 and 1949. The glacier was mapped in detail from air photos taken by the Ronne Antarctic Research Expedition, 1947–48, by D. Searle of the FIDS in 1960. It was named by the UK Antarctic Place-Names Committee after the minor planet Eros in association with nearby Pluto Glacier and Uranus Glacier.
Monteverdi Peninsula is a large ice-covered peninsula lying between the Bach Ice Shelf and George VI Sound, forming the southernmost extremity of Alexander Island, Antarctica. The southern side of the feature was first seen and charted by Finn Ronne and Carl Eklund of the United States Antarctic Service, 1939–41, who traversed the entire length of George VI Sound. The peninsula was mapped from trimetrogon air photography taken by the Ronne Antarctic Research Expedition in 1947–48, and from survey by the Falkland Islands Dependencies Survey, 1948-50. It was named by the UK Antarctic Place-Names Committee after Italian composer Claudio Monteverdi.
Mercury Glacier is a glacier on the east coast of Alexander Island, Antarctica, 5 nautical miles (9 km) long and 2 nautical miles (4 km) wide, flowing east into George VI Sound between the Waitabit Cliffs and Keystone Cliffs. The glacier was probably first sighted from a distance by Lincoln Ellsworth, who flew near it and photographed segments of this coast on November 23, 1935. It was named by the UK Antarctic Place-Names Committee for the planet Mercury following rough surveys from George VI Sound by the Falkland Islands Dependencies Survey (FIDS) in 1948 and 1949. The glacier was mapped in detail from air photos taken by the Ronne Antarctic Research Expedition, 1947–48, by D. Searle of the FIDS in 1960. Although Mercury Glacier is not located within the Planet Heights, it is named in association with the heights along with many other nearby glaciers named after planets of the Solar System.
Stephenson Nunatak is a prominent, pyramid-shaped rock nunatak, rising to about 640 m, which rises 300 m above the surrounding ice at the northwest side of Kirwan Inlet in the southeast part of Alexander Island, Antarctica. Discovered and roughly surveyed in 1940-41 by Ronne and Eklund of the United States Antarctic Service. Resurveyed in 1949 by the Falkland Islands Dependencies Survey and named by the United Kingdom Antarctic Place-Names Committee for Alfred Stephenson, surveyor with the British Graham Land Expedition, who led a sledge party south into George VI Sound to about 72S in 1936. There happens to be another landform on Alexander Island which is named after Alfred Stephenson, that being Mount Stephenson, the highest point of Alexander Island rising to 2,987 m.
Rymill Coast is that portion of the west coast of Antarctic Peninsula between Cape Jeremy and Buttress Nunataks. It runs northward from English Coast and east of Alexander Island across George VI Sound. It is joined in the north by Fallieres Coast, which runs along Marguerite Bay. It was named by the United Kingdom Antarctic Place-Names Committee (UK-APC) in 1985 after John Riddoch Rymill (1905–68), Australian leader of the BGLE, 1934-37.
Robillard Glacier is a narrow glacier flowing east-northeast and entering the north side of the head of Solberg Inlet, on the east coast of Graham Land. It was discovered by members of East Base of the United States Antarctic Service (USAS), 1939–41, and was photographed from the air in 1947 by the Ronne Antarctic Research Expedition (RARE), under Ronne, and charted in 1948 by the Falkland Islands Dependencies Survey (FIDS). It was named by Ronne for Captain George Robillard, U.S. Navy, of the legal section of the Bureau of Ships, who assisted in gaining Congressional support which resulted in procuring the expedition ship.
East Base on Stonington Island is the oldest American research station in Antarctica, having been commissioned by Franklin D. Roosevelt in 1939. The station was built as part of two US wintering expeditions – United States Antarctic Service Expedition (1939–1941) and Ronne Antarctic Research Expedition (1947–1948). The base covers 1,000 metres (3,300 ft) from north to south and 500 metres (1,600 ft) from east to west. The base was accorded the status of one of the Historic Sites and Monuments in Antarctica on 7 May 2004.
