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.

Sherratt Bay

Sherratt Bay is a bay between Cape Melville and Penguin Island on the south side of King George Island, in the South Shetland Islands. The existence of the bay was known and roughly charted by sealers working in the area in the early 1820s. It was named by the United Kingdom Antarctic Place-Names Committee (UK-APC) in 1960 for Richard Sherratt, Master of the Lady Trowbridge from Liverpool which was wrecked off Cape Melville on December 25, 1820. Sherratt occupied his time until rescued by making an inaccurate but historically interesting map of the South Shetland Islands.

South Shetland Islands A group of islands north of the Antarctic Peninsula

The South Shetland Islands are a group of Antarctic islands with a total area of 3,687 square kilometres (1,424 sq mi). They lie about 120 kilometres (75 mi) north of the Antarctic Peninsula, and between 430 kilometres (270 mi) to 900 kilometres (560 mi) south-west from the nearest point of the South Orkney Islands. By the Antarctic Treaty of 1959, the islands' sovereignty is neither recognized nor disputed by the signatories and they are free for use by any signatory for non-military purposes.

United States Geological Survey Scientific agency of the United States government

The United States Geological Survey is a scientific agency of the United States government. The scientists of the USGS study the landscape of the United States, its natural resources, and the natural hazards that threaten it. The organization has four major science disciplines, concerning biology, geography, geology, and hydrology. The USGS is a fact-finding research organization with no regulatory responsibility.

Geographic Names Information System geographical database

The Geographic Names Information System (GNIS) is a database that contains name and locative information about more than two million physical and cultural features located throughout the United States of America and its territories. It is a type of gazetteer. GNIS was developed by the United States Geological Survey in cooperation with the United States Board on Geographic Names (BGN) to promote the standardization of feature names.

OCain Point

O'Cain Point is a point lying 3 nautical miles (6 km) northwest of Duthoit Point on the east side of Nelson Island, in the South Shetland Islands. The name O'Cain's Island, after the American sealing vessel O'Cain from Boston, MA, was applied by the Stonington sealers in 1820-21 to Nelson Island, but this name did not become established. O'Cain Point was applied by the United Kingdom Antarctic Place-Names Committee (UK-APC) in 1961 to preserve the American name in the area.

Bell Point is a rocky headland lying 11 km (7 mi) southwest of Stigant Point near the western end of King George Island, in the South Shetland Islands of Antarctica. It was charted, and named "Rocky Point", by Discovery Investigations personnel on the Discovery II in 1935; in order to avoid duplication, the name was rejected by the UK Antarctic Place-Names Committee in 1960 and a new one substituted. Bell Point is named for Dennis R. Bell (1934–59), a Falkland Islands Dependencies Survey meteorological assistant at Admiralty Bay from 1958 to July 26, 1959, when he lost his life in a crevasse.

Noble Glacier glacier in Antarctica

Noble Glacier is a small glacier lying just north of Flagstaff Glacier on the east side of Keller Peninsula, King George Island, in the South Shetland Islands. Named by the United Kingdom Antarctic Place-Names Committee (UK-APC) in 1960 for Hugh M. Noble of Falkland Islands Dependencies Survey (FIDS), glaciologist at Admiralty Bay in 1957, who made detailed studies of the regime of Flagstaff and Stenhouse Glaciers.

Striped Hill is a small ice-free hill, 90 m, standing near the south shore of Trinity Peninsula, 1 nautical mile (1.9 km) east-northeast of Church Point. Charted and named by the Falkland Islands Dependencies Survey (FIDS), 1946. The descriptive name is derived from the stratifications on a small cliff on the seaward side of the hill.

Tu Rocks is a two low rocks lying in Maxwell Bay 2 nautical miles (3.7 km) east of the southwest end of King George Island, in the South Shetland Islands. The name appears to have been given by DI personnel on the Discovery II who charted the rocks in 1935. Tu is apparently phonetic for two.

False Island is the largest of three islands lying at the east side of Hackapike Bay, off the northeast coast of Anvers Island, in the Palmer Archipelago.

False Island was named by Discovery Investigations personnel on the Discovery in 1927.

Hole Rock

Hole Rock is the largest of several rocks lying close north of North Foreland, the northeastly cape of King George Island, in the South Shetland Islands. It was charted in 1937 by Discovery Investigations personnel on the Discovery II and so named because a conspicuous hole extends through it.
