O'Connors Rock ( 62°5′S58°24′W / 62.083°S 58.400°W / -62.083; -58.400 Coordinates: 62°5′S58°24′W / 62.083°S 58.400°W / -62.083; -58.400 ) is a rock 0.1 nautical miles (0.2 km) southwest of Stenhouse Bluff, King George Island, lying in Visca Anchorage in the north part of Admiralty Bay, in the South Shetland Islands. First charted by the French Antarctic Expedition, 1908–10, under Charcot. The name "O'Connor's Rock" was first used for this feature on a British chart and is probably after Midshipman W. P. O'Connor, Royal Navy Reserve, who assisted in a sketch survey of Visca Anchorage in the Discovery in 1927.

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.

Stenhouse Bluff is a southern face of a rocky knoll at the head of Visca Anchorage, Admiralty Bay, on King George Island in the South Shetland Islands. First charted by the French Antarctic Expedition, 1908–10, under Charcot. Named for Commander Joseph Stenhouse, Royal Navy Reserve, captain of the RRS Discovery in these waters in 1927.

Visca Anchorage cove

Visca Anchorage is the northwestern cove of Martel Inlet, Admiralty Bay, at King George Island in the South Shetland Islands. Charted by the French Antarctic Expedition, 1908–10, under Charcot, and named by him for Dr. Visca, an acquaintance in Montevideo.

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.

Emm Rock is a conspicuous rock 30 metres (100 ft) high, lying 0.5 nautical miles (1 km) off the south coast of King George Island at the east side of the entrance to Potter Cove, in the South Shetland Islands. This rock, presumably known to early sealers in the area, was sketched by the French Antarctic Expedition, 1908–10, under Jean-Baptiste Charcot, and charted by Discovery Investigations personnel on the Discovery II in 1935. The name derives from the shape of the rock, which resembles the letter M.
