Søstrene Islands

Last updated

Søstrene Islands ( 69°33′S75°30′E / 69.550°S 75.500°E / -69.550; 75.500 Coordinates: 69°33′S75°30′E / 69.550°S 75.500°E / -69.550; 75.500 ) is a group of small islands and rocks that rise above the northern part of the Publications Ice Shelf at the head of Prydz Bay. They were discovered and charted in February 1935 by Captain Klarius Mikkelsen in the Norwegian whaling ship Thorshavn, sent out by Lars Christensen. They gave the name Søstrene after the islands by that name lying in the entrance to the Oslofjord, Norway. [1]

Geographic coordinate system Coordinate system

A geographic coordinate system is a coordinate system that enables every location on Earth to be specified by a set of numbers, letters or symbols. The coordinates are often chosen such that one of the numbers represents a vertical position and two or three of the numbers represent a horizontal position; alternatively, a geographic position may be expressed in a combined three-dimensional Cartesian vector. A common choice of coordinates is latitude, longitude and elevation. To specify a location on a plane requires a map projection.

Publications Ice Shelf is an ice shelf about 35 nautical miles (60 km) long on the south shore of Prydz Bay, between Mount Caroline Mikkelsen and Stornes Peninsula. Several glaciers, listed from southwest to northeast, nourish the ice shelf: Polar Times Glacier, Il Polo Glacier, Polarforschung Glacier, Polar Record Glacier and Polararboken Glacier. The feature was first mapped from air photos by the Lars Christensen Expedition, 1936-37. The name "Publication Glacier Tongues" was applied by John H. Roscoe in 1952 following his study of U.S. Navy Operation Highjump (1946–47) air photos of the area, but the term ice shelf is more descriptive. So named by Roscoe because the several glaciers in the area commemorate polar publications.

Prydz Bay bay

Prydz Bay is a deep embayment of Antarctica between the Lars Christensen Coast and Ingrid Christensen Coast. The Bay is at the downstream end of a giant glacial drainage systems that originates in the East Antarctic interior. The Lambert Glacier flows from Lambert Graben into the Amery Ice Shelf on the south-west side of Prydz Bay. Other major glaciers drain into the southern end of the Amery Ice Shelf at 73° S where the marine part of the system starts at the modern grounding zone.

The Søstrene Islands include Debutante Island.

Cape Longing Refuge in Argentina

Cape Longing is a rocky cape on the east coast of Graham Land, Antarctica, forming the south end of a large ice-covered promontory which marks the west side of the south entrance to Prince Gustav Channel. It was discovered by the Swedish Antarctic Expedition under Otto Nordenskiöld in 1902, and so named by him because from the position of his winter hut on Snow Hill Island the cape lay in the direction of his "land of longing" which he was anxious to explore.

Wilson Hills is a group of scattered hills, nunataks and ridges that extend NW-SE for about 110 kilometres (68 mi) between Matusevich Glacier and Pryor Glacier in Antarctica. They were discovered by Lieutenant Harry Pennell, Royal Navy, on the Terra Nova Expedition in February 1911 during Robert Falcon Scott's last expedition, and named after Dr. Edward A. Wilson, a zoologist with the expedition, who perished with Scott on the return journey from the South Pole.

Shaw Nunatak

Shaw Nunatak is a nunatak rising to 500 m in Nichols Snowfield, northern Alexander Island, Antarctica. It is situated 5.3 km north-northeast of Rachenitsa Nunatak, 4.23 km east-southeast of Tipits Knoll and 7 km southeast of Mount Kliment Ohridski in Sofia University Mountains, 7.5 km southwest of Lizard Nunatak and 8.1 km northwest of Tegra Nunatak. The feature was photographed from the air by Ronne Antarctic Research Expedition in 1947–48, and mapped from these photographs by D. Searle of Falkland Islands Dependencies Survey, 1960. The nunatak was named by United Kingdom Antarctic Place-Names Committee in 1977 after Colin Shaw (1944–78), British Antarctic Survey surveyor who worked in Alexander Island, from 1975 to 1976.

Debutante Island

Debutante Island is a narrow island which is the southernmost of the Søstrene Islands. The island is ice-covered except for a small rock outcrop and barely protrudes above the general level of the Publications Ice Shelf. It was mapped by Norwegian cartographers from aerial photographs taken by the Lars Christensen Expedition, 1936–37, and was named "Debutante" in 1952 by John H. Roscoe because the island is just beginning to "come out" from under its ice cover.

Zonda Glacier is a glacier about 8 miles long, flowing west-southwest between Fohn Bastion and Zonda Towers into George VI Sound. The glacier was included in surveys by Falkland Islands Dependencies Survey (FIDS), 1948, and British Antarctic Survey (BAS), 1971-72, and was photographed from the air by the U.S. Navy, 1966. The name applied by United Kingdom Antarctic Place-Names Committee (UK-APC) in 1977 continues the theme of wind names in the area, as "zonda wind" is the Argentine name for the warm dry wind descending the east slopes of the Andes.

Coast Lake is a small lake at Cape Royds, Ross Island in the Antarctic region, lying close to the coastline, about 0.75 nautical miles (1.4 km) north of Flagstaff Point. It was named by the British Antarctic Expedition, 1907–09, because of its position.

Named by Advisory Committee on Antarctic Names (US-ACAN) for Gary Walsh, United States Antarctic Research Program (USARP) biologist at Hallett Station, 1968-69.

Crume Glacier glacier in Antarctica

Crume Glacier is a tributary glacier, 5 nautical miles (9 km) long, flowing east to enter Ommanney Glacier near the north coast of Victoria Land, Antarctica. The geographical feature was first mapped by the United States Geological Survey from surveys and from U.S. Navy air photos, 1960–63, and named by the Advisory Committee on Antarctic Names for William R.

Minamino-seto Strait is a narrow strait between Ongul Island and the Te Islands in the Flatvaer Islands of Antarctica. It was mapped by Norwegian cartographers from air photos taken by the Lars Christensen Expedition, 1936–37. The strait was surveyed by the Japanese Antarctic Research Expedition, 1957–62, and named "Minamino-seto" because of its location in the island group.

Heidemann Glacier is a glacier, 5 nautical miles (9 km) long, originating close northwest of Mount Damm in the Queen Elizabeth Range of Antarctica and flowing east into Lowery Glacier. It was mapped by the United States Geological Survey from tellurometer surveys and Navy air photos, 1960–62, and was named by the Advisory Committee on Antarctic Names for Richard P. Heidemann, a United States Antarctic Research Program glaciologist at Roosevelt Island, 1962–63.

The Herrmann Mountains are a group of rocky elevations including the Hamrane Heights and the Roots Heights, rising between Reece Valley and Kvitsvodene Valley in the Sverdrup Mountains of Queen Maud Land, Antarctica. They were discovered by the Third German Antarctic Expedition under Alfred Ritscher, 1938–39, and named for Ernst Herrmann, the geographer of the expedition. They were surveyed by the Norwegian–British–Swedish Antarctic Expedition, 1949–52.

The Mayer Hills are low, mainly ice-covered hills with steep north-facing slopes but rather featureless summits, to about 900 metres (3,000 ft), lying south of Forster Ice Piedmont, on the Antarctic Peninsula, between Prospect Glacier and Mount Leo.They were first roughly surveyed from the ground by the British Graham Land Expedition, 1936–37. The hills were resurveyed by the Falkland Islands Dependencies Survey in 1958, and were named by the UK Antarctic Place-Names Committee after Johann Tobias Mayer (1723–1762), a German mathematician who constructed a series of lunar tables for determining longitude, published by the British Admiralty in 1775.
