Stange Ice Shelf
Stange Ice Shelf (), is an Antarctic ice shelf in Stange Sound, English Coast, bounded to the east by Spaatz Island, to the northwest by Smyley Island, and to the west by fast ice in Carroll Inlet. Named in association with Stange Sound. In contrast to the some other ice shelves on the Antarctic Peninsula, for example the Larsen Ice Shelf, the Stange Ice Shelf has been relatively stable.

Ice Shelf
An ice shelf is a large floating platform of ice that forms where a glacier or ice sheet flows down to a coastline and onto the ocean surface. Ice shelves are only found in Antarctica, Greenland, Northern Canada, and the Russian Arctic. The boundary between the floating ice shelf and the anchor ice (resting on bedrock) that feeds it is the grounding line. The thickness of ice shelves can range from about to . In contrast, sea ice is formed on water, is much thinner (typically less than ), and forms throughout the Arctic Ocean. It is also found in the Southern Ocean around the continent of Antarctica. The movement of ice shelves is principally driven by gravity-induced pressure from the grounded ice. That flow continually moves ice from the grounding line to the seaward front of the shelf. In steady state, about half of Antarctica's ice shelf mass is lost to basal melt and half is lost to calving, but the relative importance of each process varies significantly between ice s ...

Stange Sound
Stange Sound () is a sound about 60 nautical miles (110 km) long and 25 nautical miles (46 km) wide along the coast of Palmer Land, Antarctica. An ice shelf occupies the sound, which is bounded on the west by Smyley and Case Islands, on the south by the mainland, on the east by Spaatz Island and on the north by open water in Ronne Entrance. Photographed from the air and roughly plotted by the Ronne Antarctic Research Expedition (RARE) (1947–48) under Finn Ronne. Named for Henry Stange of New York City New York, often called New York City or NYC, is the most populous city in the United States.

English Coast
English Coast is a portion of the coast of Antarctica between the northern tip of Rydberg Peninsula and the Buttress Nunataks, on the west side of Palmer Land. To the west is Bryan Coast, and northward runs Rymill Coast east of Alexander Island across George VI Sound. This coast was discovered and explored in 1940, on land by Finn Ronne and Carl R. Eklund and from the air by other members of the East Base of the US Antarctic Service (USAS), 1939–41. It was originally named "Robert English Coast" after Capt. Robert A.J. English, US Navy, Executive Secretary of USAS, 1939–41, and formerly Captain of the '' Bear of Oakland'' on the Byrd Antarctic Expedition Richard Evelyn Byrd Jr. (October 25, 1888 – March 11, 1957) was an American naval officer and explorer.

Spaatz 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, east of Smyley Island. It is long and wide, and covers an area of around . The north side of the island forms a portion of the south margin of Ronne Entrance; the remainder of the island is surrounded by the ice shelves of Stange Sound and George VI Sound. Finn Ronne and Carl Eklund of the US Antarctic Service (USAS) (1939–41) sledged along the north side of this feature in December 1940. It was photographed from the air and first mapped as an island by the Ronne Antarctic Research Expedition (RARE) (1947–48) under Finn Ronne. It was named by Ronne for Gen. Carl Spaatz, Chief of Staff, USAAF, who gave assistance in providing an airplane for use of RARE.

Smyley Island
Smyley Island is an Antarctic island lying off the Antarctic Peninsula. The island is long and from wide, and lies about north of Case Island. It connects to the Stange Ice Shelf and is separated from Alexander Island by the Ronne Entrance. Smyley Island is one of the 27 islands of Palmer Land, Antarctica. Discovery and naming In 1939–1941 Smyley Island was first identified as a peninsula of mainland Antarctica by the United States Antarctic Service and was named ''Cape Smyley''. In 1968 it was identified as an island on a U.S. Geological Survey map. The island is named after Captain William H. Smyley, the American master of the sealing vessel ''Ohio'' during 1841–42. Important Bird Area A 497 ha site on fast ice near Scorseby Head, on the northern shore of the island, has been designated an Important Bird Area (IBA) by BirdLife International because it supports a breeding colony of some 6,000 emperor penguins, based on 2009 satellite imagery.

Carroll Inlet
Carroll Inlet () is an inlet, long and wide, trending southeast along the coast of Antarctica between the Rydberg Peninsula and Smyley Island. The head of the inlet is divided into two arms by the presence of Case Island and is bounded to the east by Stange Ice Shelf. It was discovered on an airplane flight, 22 December 1940, by members of the United States Antarctic Service The United States Antarctic Program (or USAP; formerly known as the United States Antarctic Research Program or USARP and the United States Antarctic Service or USAS) is an organization of the United States government which has presence in the A ...

Geographic Names Information System
The Geographic Names Information System (GNIS) is a database of name and locative information about more than two million physical and cultural features throughout the United States and its territories, Antarctica, and the associated states of the Marshall Islands, Federated States of Micronesia, and Palau. It is a type of gazetteer. It was developed by the United States Geological Survey (USGS) in cooperation with the United States Board on Geographic Names (BGN) to promote the standardization of feature names. Data were collected in two phases. Although a third phase was considered, which would have handled name changes where local usages differed from maps, it was never begun. The database is part of a system that includes topographic map names and bibliographic references. The names of books and historic maps that confirm the feature or place name are cited. Variant names, alternatives to official federal names for a feature, are also recorded. Each feature receives a per ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Antarctic Peninsula
The Antarctic Peninsula, known as O'Higgins Land in Chile and Tierra de San Martín in Argentina, and originally as Graham Land in the United Kingdom and the Palmer Peninsula in the United States, is the northernmost part of mainland Antarctica. The Antarctic Peninsula is part of the larger peninsula of West Antarctica, protruding from a line between Cape Adams (Weddell Sea) and a point on the mainland south of the Eklund Islands. Beneath the ice sheet that covers it, the Antarctic Peninsula consists of a string of bedrock islands; these are separated by deep channels whose bottoms lie at depths considerably below current sea level. They are joined by a grounded ice sheet. Tierra del Fuego, the southernmost tip of South America, is about away across the Drake Passage. The Antarctic Peninsula is in area and 80% ice-covered. The marine ecosystem around the western continental shelf of the Antarctic Peninsula (WAP) has been subjected to rapid climate change. Over the past 50 ...

Larsen Ice Shelf
The Larsen Ice Shelf is a long ice shelf in the northwest part of the Weddell Sea, extending along the east coast of the Antarctic Peninsula from Cape Longing to Smith Peninsula. It is named after Captain Carl Anton Larsen, the master of the Norwegian whaling vessel ''Jason'', who sailed along the ice front as far as 68°10' South during December 1893. In finer detail, the Larsen Ice Shelf is a series of shelves that occupy (or occupied) distinct embayments along the coast. From north to south, the segments are called Larsen A (the smallest), Larsen B, and Larsen C (the largest) by researchers who work in the area. Further south, Larsen D and the much smaller Larsen E, F and G are also named. The breakup of the ice shelf since the mid-1990s has been widely reported, with the collapse of Larsen B in 2002 being particularly dramatic. A large section of the Larsen C shelf broke away in July 2017 to form an iceberg known as A-68. The ice shelf originally covered an area of , but ...
