Liberty Rocks is a group of four prominent adjacent rocks lying at the north entrance to Nelson Strait in the South Shetland Islands, Antarctica and extending 430 by 120 m (470 by 131 yd). The area was visited by early 19th-century sealers.
Nelson Strait is the 9 km long and 9.8 km wide strait lying between Robert Island and Nelson Island in the South Shetland Islands, Antarctica. The strait was explored by early 19th century sealers and first charted by Nathaniel Palmer in 1821. While it had a variety of different names in the past, the present name — probably taken from the adjacent Nelson Island — has become well established in international usage.
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.
Antarctica is Earth's southernmost continent. It contains the geographic South Pole and is situated in the Antarctic region of the Southern Hemisphere, almost entirely south of the Antarctic Circle, and is surrounded by the Southern Ocean. At 14,200,000 square kilometres, it is the fifth-largest continent. For comparison, Antarctica is nearly twice the size of Australia. About 98% of Antarctica is covered by ice that averages 1.9 km in thickness, which extends to all but the northernmost reaches of the Antarctic Peninsula.
The feature is named after the British sealing vessel Liberty under Captain Peacock that visited the South Shetlands in 1821–22.
The rocks are centred at 62°18′50.6″S59°27′44.2″W / 62.314056°S 59.462278°W which is 3.95 km (2.45 mi) northeast of Newell Point, Robert Island, 1.65 km (1.03 mi) southeast of Mellona Rocks, 11.38 km (7.07 mi) west by south of Harmony Point, Nelson Island and 6 km (3.73 mi) northwest of Makresh Rocks (British mapping in 1822, 1962 and 1968, Chilean in 1971, Argentine in 1980, and Bulgarian in 2009).
Newell Point is the rocky point forming the northeast extremity of Robert Island in the South Shetland Islands, Antarctica and is a northwest entrance point of Nelson Strait.
Mellona Rocks is a group of scattered rocks lying at the north entrance to Nelson Strait in the South Shetland Islands, Antarctica and extending 1.7 by 0.9 km. The area was known to the early 19th-century sealers and sometimes included under the names 'Heywood Islands' or 'Powels Islands'.
Harmony Point is a point which lies close west of Harmony Cove and forms the western extremity of Nelson Island, in the South Shetland Islands of Antarctica. It was charted in 1935 by Discovery Investigations personnel on the Discovery II, and named from association with Harmony Cove.
The Scientific Committee on Antarctic Research (SCAR) is an interdisciplinary body of the International Council for Science (ICSU).
There are seven sovereign states who currently maintain de jure, largely symbolic territorial claims in Antarctica: Argentina, Australia, Chile, France, New Zealand, Norway and the United Kingdom. These countries have tended to place their Antarctic scientific observation and study facilities within their respective claimed territories; however, a number of such facilities are located nowhere near the sectors claimed by their respective countries of operation, and there are multiple other countries such as Russia and the United States who, despite having no territorial claim of their own anywhere in Antarctica, have constructed large research facilities within the sectors claimed by other countries.
