Jacobel Glacier ( 77°44′S148°17′W / 77.733°S 148.283°W / -77.733; -148.283 Coordinates: 77°44′S148°17′W / 77.733°S 148.283°W / -77.733; -148.283 ) is a glacier about 30 miles (50 km) long draining to the Sulzberger Ice Shelf, Antarctica, south of Hershey Ridge. It was named by the Advisory Committee on Antarctic Names after Robert W. Jacobel, holder of the Grace A. Whittier Chair of Physics at St. Olaf College, Northfield, Minnesota. An Antarctic researcher from the 1980s onwards, his research interests include the combination of ground-based radar and ice core studies in West Antarctica. [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.

Glacier Persistent body of ice that is moving under its own weight

A glacier is a persistent body of dense ice that is constantly moving under its own weight; it forms where the accumulation of snow exceeds its ablation over many years, often centuries. Glaciers slowly deform and flow due to stresses induced by their weight, creating crevasses, seracs, and other distinguishing features. They also abrade rock and debris from their substrate to create landforms such as cirques and moraines. Glaciers form only on land and are distinct from the much thinner sea ice and lake ice that form on the surface of bodies of water.

Hershey Ridge is a low, ice-covered ridge trending in a northwest–southeast direction for about 30 nautical miles (56 km) between McKinley Peak and the Haines Mountains, in the Ford Ranges of Marie Byrd Land, Antarctica. It was discovered in 1934 by the Byrd Antarctic Expedition, and named for Garland Hershey, Assistant State Geologist of the Iowa Geological Survey (1939–47) and Director of the Iowa Geological Survey after 1947.

Dater Glacier glacier in Antarctica

The Dater Glacier is a steep valley glacier in Antarctica, 24 nautical miles long and from 1 to 3 nautical miles wide, flowing northeast in a sinuous course from the eastern slopes of the Vinson Massif between Sullivan Heights and Veregava Ridge to Rutford Ice Stream which borders the eastern flank of the Sentinel Range, Ellsworth Mountains. At the lower end the Dater Glacier coalesces with the terminus of the Ellen Glacier, the two emerging from the Sentinel Range as one stream just north of the Flowers Hills.

Drygalski Glacier (Antarctica) glacier in Antarctica

Drygalski Glacier is a broad glacier, 18 nautical miles long and 15 miles (24 km) wide at its head, which flows from Herbert Plateau southeast between Ruth Ridge and Kyustendil Ridge, and enters Solari Bay immediately north of Sentinel Nunatak on Nordenskjöld Coast, the east coast of Graham Land, Antarctica. It was discovered in 1902 by the Swedish Antarctic Expedition, under Otto Nordenskiöld, and named "Drygalski Bay" after Professor Erich von Drygalski. The feature was determined to be a glacier by the Falkland Islands Dependencies Survey in 1947.

Dibble Glacier glacier in Antarctica

Dibble Glacier in Antarctica is a prominent channel glacier flowing from the continental ice and terminating in a prominent tongue at the east side of Davis Bay. It was delineated from air photos taken by U.S. Navy Operation Highjump (1946–47), and named by the Advisory Committee on Antarctic Names for Jonas Dibble, ship's carpenter on the sloop Peacock of the United States Exploring Expedition (1838–42) under Charles Wilkes. Dibble is credited with leaving his sick bed and working 24 hours without relief with other carpenters to repair a broken rudder on the Peacock, when the ship was partially crushed in an ice bay in 151°19′E and forced to retire northward.

Horlick Ice Stream

Horlick Ice Stream is a large ice stream on the featureless ice surface to the north of the main mass of the Horlick Mountains of Antarctica, draining west-southwestward, parallel to these mountains, to enter the lower portion of the Reedy Glacier.

Arthur Glacier is a valley glacier in Antarctica. It is about 25 nautical miles (50 km) long, and flows west to Sulzberger Ice Shelf between the Swanson Mountains on the north and Mount Rea and Mount Cooper on the south, in the Ford Ranges of Marie Byrd Land. It was discovered by members of West Base of the United States Antarctic Service, in aerial flights and from ground surveys in November–December 1940. It was named by the Advisory Committee on Antarctic Names for Rear Admiral Arthur C. Davis, a leader in aviation in the U.S. Navy.

The glacier was photographed from the air in December 1940 by the United States Antarctic Service (USAS), and was probably seen by the USAS ground survey party which explored this coast. A joint party consisting of members of the Ronne Antarctic Research Expedition and the Falkland Islands Dependencies Survey (FIDS) charted the glacier in 1947. It was named by the FIDS for L. Ashton, a carpenter with the FIDS at the Port Lockroy and Hope Bay bases in 1944–45 and 1945–46, respectively.

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.
