Last updated

Edisto Channel ( 66°5′S100°50′E / 66.083°S 100.833°E / -66.083; 100.833 Coordinates: 66°5′S100°50′E / 66.083°S 100.833°E / -66.083; 100.833 ) is a marine channel, whose south end is filled by Edisto Ice Tongue. It extends in a northeast–southwest direction between the Taylor Islands and the northwestern islands of the Highjump Archipelago on the west, and the Bunger Hills, Thomas Island, and the remaining islands in the Highjump Archipelago on the east. It was delineated from aerial photographs taken by U.S. Navy Operation Highjump, 1946–47, and was named by the Advisory Committee on Antarctic Names for the USS Edisto, one of the two icebreakers of Operation Windmill, 1947–48, which assisted in establishing astronomical control stations along Wilhelm II Coast, Queen Mary Coast, Knox Coast and Budd Coast.

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.

Edisto Ice Tongue is an ice tongue along the northwest margin of the Bunger Hills where it occupies the southwestern portion of Edisto Channel, in the Highjump Archipelago. The ice tongue is a seaward extension of the flow of Apfel Glacier as well as part of the main flow of Scott Glacier. It was mapped from air photos taken by U.S. Navy Operation Highjump, 1946–47, and was named by the Advisory Committee on Antarctic Names in association with Edisto Channel.

Taylor Islands is a group of rocky islands and rocks lying at the west side of Edisto Ice Tongue and marking the west end of the Highjump Archipelago. Delineated from aerial photographs taken by U.S. Navy Operation Highjump, 1946–47, and named for Richard Spence Taylor, who served as surveyor with the U.S. Navy Operation Windmill parties which established astronomical control stations from Wilhelm II Coast to Budd Coast in January–February 1948.

Cape Folger is an ice-covered cape forming the east side of the entrance to Vincennes Bay on the Budd Coast of Antarctica. The position of Cape Folger correlates closely with the west end of Charles Wilkes' "Budd's High Land", as charted as a coastal landfall by the United States Exploring Expedition in 1840. The cape was mapped from aerial photographs taken by U.S. Navy Operation Highjump, 1946–47, and was named by the Advisory Committee on Antarctic Names for Commander Edward C. Folger, Jr., U.S. Navy, commander of the icebreaker Edisto which assisted Operation Windmill parties in establishing astronomical control stations in the Windmill Islands, close southwest in Vincennes Bay.

Cape Morse

Cape Morse is a low, ice-covered cape which marks the east side of the entrance to Porpoise Bay and forms the division between Banzare Coast and Clarie Coast in Wilkes Land, Antarctica. It was delineated from air photos taken by U.S. Navy Operation Highjump in 1946–47, and was named by the Advisory Committee on Antarctic Names for William H. Morse, purser's steward on the brig Porpoise of the United States Exploring Expedition (1838–42) under Charles Wilkes.

Adams Glacier (Wilkes Land) glacier in Antarctica

Adams Glacier, also known as John Quincy Adams Glacier, is a broad channel glacier in Wilkes Land, Antarctica which is over 20 miles (32 km) long. It debouches into the head of Vincennes Bay, just east of Hatch Islands. It was first mapped in 1955 by G.D. Blodgett from aerial photographs taken by U.S. Navy Operation Highjump (1947), and it was named by the Advisory Committee on Antarctic Names (US-ACAN) for John Quincy Adams, sixth President of the United States. Adams was instrumental while later serving as U.S. representative from Massachusetts in gaining congressional authorization of the United States Exploring Expedition (1838–42) under Lieutenant Charles Wilkes, and perpetuating the compilation and publication of the large number of scientific reports based on the work of this expedition.

Posadowsky Glacier (Antarctica)

Posadowsky Glacier is a glacier about 9 nautical miles long, flowing north to Posadowsky Bay immediately east of Gaussberg. Posadowsky Bay is an open embayment, located just east of the West Ice Shelf and fronting on the Davis Sea in Kaiser Wilhelm II Land. Kaiser Wilhelm II Land is the part of East Antarctica lying between Cape Penck, at 87°43'E, and Cape Filchner, at 91°54'E, and is claimed by Australia as part of the Australian Antarctic Territory. Other notable geographic features in this area include Drygalski Island, located 45 mi NNE of Cape Filchner in the Davis Sea, and Mirny Station, a Russian scientific research station.

Mabus Point

Mabus Point is a point on the coast of Antarctica lying just south of the Haswell Islands, marking the eastern limit of McDonald Bay. It was first charted by the Australasian Antarctic Expedition, 1911–14, under Douglas Mawson, and was recharted by G.D. Blodgett in 1955 from aerial photographs taken by U.S. Navy Operation Highjump, 1946–47. The point was named by the Advisory Committee on Antarctic Names for Lieutenant Commander Howard W. Mabus, U.S. Navy, executive officer of the icebreaker Edisto, who was instrumental in providing close support to U.S. Navy Operation Windmill parties in establishing astronomical control stations along this coast, 1947–48. Mabus Point subsequently became the site of the Soviet scientific station, Mirny.

Algae Lake is a narrow, winding lake, 9 nautical miles (17 km) long and between 0.2 and 1 nautical mile wide, extending in an east–west direction in the ice-free Bunger Hills of Antarctica. It was first mapped from air photos taken by U.S. Navy Operation Highjump, 1946–47, and named "Algae Inlet" by the Advisory Committee on Antarctic Names because of the algae reported by Operation Highjump personnel, which cause varying tints to the meltwater ponds overlying the Bunger Hills and to the saline inlets and channels in the Highjump Archipelago area close to the north. Subsequent Soviet Antarctic Expeditions (1956–57) found this "inlet" to be a lake.

Apfel Glacier glacier in Antarctica

Apfel Glacier is a glacier about 5 nautical miles (10 km) wide and 20 nautical miles (40 km) long, flowing west-northwest along the south flank of the Bunger Hills and terminating in Edisto Ice Tongue. It was mapped from air photos taken by U.S. Navy Operation Highjump, 1946–47, and named by the Advisory Committee on Antarctic Names for Earl T. Apfel, professor of geology at Syracuse University, who served as geologist with the U.S. Navy Operation Windmill parties, 1947–48, which established astronomical control stations along Queen Mary, Knox and Budd Coasts.

Cacapon Inlet is an inlet about 2 nautical miles (4 km) wide and 9 nautical miles (17 km) long, lying between Thomas Island and Fuller Island in the Highjump Archipelago. The inlet is bounded on the west by Edisto Ice Tongue and on the east by the coast of Antarctica. It was mapped from aerial photographs taken by U.S. Navy Operation Highjump in February 1947, and named by the Advisory Committee on Antarctic Names after USS Cacapon, a tanker in the Western Task Group of Operation Highjump, 1946–47.

Currituck Island is an island in Antarctica 7 nautical miles (13 km) long marked by numerous small coves, lying on the northwest side of Edisto Channel in the Highjump Archipelago. It was mapped from air photos taken by U.S. Navy Operation Highjump in February, 1947, and named by the Advisory Committee on Antarctic Names in 1956 after the USS Currituck, a seaplane tender and flagship of the western task group of U.S. Navy Operation Highjump, Task Force 68, 1946–47. At that time, the northern portion was thought to be a separate feature and was named "Mohaupt Island," but subsequent Soviet Expeditions (1956–57) found that only one large island exists.

Dieglman Island

Dieglman Island is an island about 7 kilometres (4 nmi) long that is largely ice covered but has numerous rock outcrops, lying on the northwest side of Edisto Channel in the Highjump Archipelago. First mapped from air photos taken by U.S. Navy Operation Highjump, 1946–47, and named the "Dieglman Islets", subsequent Soviet expeditions (1956–57) mapped the feature as one island with numerous outcrops. The name has been altered by the Advisory Committee on Antarctic Names (US-ACAN) to apply to the single island. Named by US-ACAN for E.D. Dieglman, an air crewman on U.S. Navy Operation Highjump photographic flights in this area in 1946–47.

DuBeau Glacier glacier in Antarctica

DuBeau Glacier is a channel glacier flowing to the Antarctic coast 18 nautical miles (33 km) west of Merritt Island. It was mapped in 1955 by G.D. Blodgett from air photos taken by U.S. Navy Operation Highjump in 1947, and was named by the Advisory Committee on Antarctic Names for Earl P. DuBeau, a photo interpreter with U.S. Navy Operation Windmill (1947–48), who assisted in establishing astronomical control stations along Queen Mary Coast, Knox Coast and Budd Coast.

Elliott Glacier glacier in Antarctica

Elliott Glacier is a small channel glacier that drains northward to the Budd Coast of Antarctica, midway between Cape Hammersly and Cape Waldron. It was delineated from aerial photographs taken by U.S. Navy Operation Highjump (1946–47), and named by the Advisory Committee on Antarctic Names after Samuel Elliott, a midshipman on the sloop Vincennes during the United States Exploring Expedition (1838–42) under Lieutenant Charles Wilkes.

Mohaupt Point is the eastern point of Currituck Island, in the Highjump Archipelago, Antarctica. The name "Mohaupt Island" was given by Advisory Committee on Antarctic Names (US-ACAN) in 1956 to the northern portion of Currituck Island, then thought to be a separate feature. Subsequent Soviet expeditions in 1956–57 found that feature to be part of Currituck Island and US-ACAN has reapplied the name to the point described. It is named for H.E. Mohaupt, an air crewman on U.S. Navy Operation Highjump photographic flights in this area in 1946–47.

Gossard Channel is a narrow channel extending in an east–west direction between the Mariner Islands and Booth Peninsula in the central portion of the Highjump Archipelago, Antarctica. It was mapped from air photos taken by U.S. Navy Operation Highjump, 1946–47, and named by the Advisory Committee on Antarctic Names for G.C. Gossard, Jr., an air crewman on Operation Highjump photographic flights in this area and other coastal areas between 14°E and 164°E.

The Highjump Archipelago is a group of rocky islands, rocks and ice rises in Antarctica, about 93 kilometres (50 nmi) long and from 9 to 28 kilometres wide, lying generally north of the Bunger Hills and extending from the Taylor Islands, close northwest of Cape Hordern, to a prominent group of ice rises which terminate close west of Cape Elliott. It was delineated from aerial photographs taken by U.S. Navy Operation Highjump 1946–47 and so named by the Advisory Committee on Antarctic Names. The codeword "highjump" was used for identifying the U.S. Navy Task Force 68, 1946–47. This task force was divided into three groups which completed photographic flights covering approximately 70 per cent of the coastal areas of Antarctica, excluding the Antarctic Peninsula, as well as significant portions of the interior.

Mariner Islands

The Mariner Islands are a group of rocky islands and rocks forming the north-central group of the Highjump Archipelago, bounded by Edisto Channel on the west, Gossard Channel on the south, and Remenchus Glacier on the east. They were mapped from air photos taken by U.S. Navy Operation Highjump, 1946–47, and named by the Advisory Committee on Antarctic Names to commemorate the discovery of a large ice-free region at the west end of the Knox Coast by the crew of a Martin PBM Mariner seaplane commanded by D.E. Bunger. During photographic reconnaissance of this coastal area in January 1947, the aircraft landed on one of the inlets indenting the Bunger Hills and ground-level photographs and water samples were obtained at that time.

Sandford Glacier glacier in Antarctica

Sandford Glacier is a channel glacier flowing to the east side of Porpoise Bay, about 25 nautical miles (46 km) south-southwest of Cape Morse. Delineated from air photos taken by U.S. Navy Operation Highjump (1946–47). Named by Advisory Committee on Antarctic Names (US-ACAN) for Joseph P. Sandford, Passed Midshipman on the brig Porpoise of the United States Exploring Expedition (1838–42) under Wilkes.

Thomas Island is a large Antarctic island in the Highjump Archipelago, 6 nautical miles (11 km) long and from 1 to 3 nautical miles (6 km) wide. It lies near the center of the main cluster of islands off the north flank of the Bunger Hills.
