The Bragg Islands ( 66°28′S66°26′W / 66.467°S 66.433°W Coordinates: 66°28′S66°26′W / 66.467°S 66.433°W ) are a small group of islands in Crystal Sound, about 7 nautical miles (13 km) north of Cape Rey, Graham Land. They were mapped from surveys by the Falkland Islands Dependencies Survey (1958–59) and from air photos obtained by the Ronne Antarctic Research Expedition (1947–48). The group was named by the UK Antarctic Place-Names Committee for Sir William H. Bragg, an English physicist who interpreted X-ray measurements to give the location of oxygen atoms in the structure of ice. [1]
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.
Crystal Sound is a sound in Antarctica between the southern part of the Biscoe Islands and the coast of Graham Land, with northern limit Cape Evensen to Cape Leblond and southern limit Holdfast Point, Roux Island, Liard Island and the Sillard Islands. It was so named by the UK Antarctic Place-Names Committee in 1960 because many features in the sound are named for men who have undertaken research on the structure of ice crystals. To the north of Crystal Sound, many geographical features are named after physiologists.
Cape Rey is a dark rocky cape between the southwest side of Darbel Bay and the northeast side of Lallemand Fjord, on the west coast of Graham Land. Discovered by the French Antarctic Expedition, 1908–10, under Charcot, and named by him for Lieutenant Joseph J. Rey, French Navy, meteorologist of the French Antarctic Expedition under Charcot, 1903-05.
Decazes Island is an island 0.8 km (0.5 mi) long, lying 2.4 km (1.5 mi) southwest of Belding Island at the southwestern extremity of the Biscoe Islands. The island is one of the largest of many small islets and rocks that fringe the northern side of Matha Strait. The vicinity was charted by the French Antarctic Expedition, 1908–10, under Jean-Baptiste Charcot, who applied the name "Pointe Decazes" to the south end of an island in this approximate position. The original application has been altered in recent years, and the name Decazes is now established in usage for the entire island described.
Atom Rock is an insular rock 0.5 miles (0.8 km) northeast of Rambler Island in the Bragg Islands, lying in Crystal Sound off the west coast of Graham Land. It was mapped from surveys by the Falkland Islands Dependencies Survey (1958–59), and named by the UK Antarctic Place-Names Committee in association with Bragg Islands.
Bedford Island is an island about 1 nautical mile (2 km) long, lying at the south end of the Barcroft Islands in the Biscoe Islands. It was mapped from air photos taken by the Falkland Islands and Dependencies Aerial Survey Expedition (1956–57), and named by the UK Antarctic Place-Names Committee for Thomas Bedford, an English physicist who specialized in the measurement of the physical environment of man.
The Bernal Islands are a group of four mainly snow-covered islands and a number of rocks lying in Crystal Sound, about 10 nautical miles (20 km) east of the south end of Lavoisier Island, Biscoe Islands. They were mapped from surveys by the Falkland Islands Dependencies Survey (1958–59) and from air photos obtained by the Ronne Antarctic Research Expedition (1947–48), and named by the UK Antarctic Place-Names Committee for John D. Bernal, a British physicist, joint author with Sir Ralph Fowler of a classic 1933 paper on the structure of ice which suggested the location of the hydrogen atoms, known as the ice rules.

It was discovered and roughly plotted from air photos by the Third German Antarctic Expedition, 1938–39. It was mapped from air photos and surveys by the Sixth Norwegian Antarctic Expedition, 1958–59, was remapped by the Soviet Antarctic Expedition, 1960–61, and named "Gora Ekho".
The Fowler Islands are a group of small islands lying between the Bernal Islands and the Bragg Islands in Crystal Sound, off the coast of Antarctica. They were mapped from air photos obtained by the Ronne Antarctic Research Expedition (1947–48) and the Falkland Islands and Dependencies Aerial Survey Expedition (1956–57), and from surveys by the Falkland Islands Dependencies Survey (1958–59). They were named by the UK Antarctic Place-Names Committee for Sir Ralph H. Fowler (1889–1944), an English physicist, joint author with J.D. Bernal of a classic paper in 1933 on the structure of ice which suggested the location of the hydrogen atoms now known as the ice rules.
Gibbs Glacier is a glacier, 15 nautical miles (28 km) long, flowing southeast into the northern part of Mercator Ice Piedmont on the east side of the Antarctic Peninsula. This feature together with Neny Glacier, which flows northwest, occupy a transverse depression between Mercator Ice Piedmont and Neny Fjord on the west side of the Antarctic Peninsula. Gibbs Glacier was photographed from the air and first mapped by the United States Antarctic Service, 1939–41, and the Ronne Antarctic Research Expedition, 1947–48. It was named by the UK Antarctic Place-Names Committee for Peter M. Gibbs of the Falkland Islands Dependencies Survey, a surveyor at Horseshoe Island, 1957, and leader at Stonington Island, 1958, who was responsible for the first ground survey of the glacier.
Goff Glacier is a broad glacier flowing from Parker Peak into the head of Koether Inlet on the north side of Thurston Island, Antarctica.

It was delineated from aerial photos taken by U.S. Navy Operation Highjump, 1946–47, and was named by the Advisory Committee on Antarctic Names for Mario Marret, the leader of the French Antarctic Expedition, 1952–53, whose party extended reconnaissance of the coastal features to the west side of Victor Bay.
Mackerel Island is an island immediately west of Flounder Island in the Fish Islands, off the west coast of Graham Land, Antarctica. It was charted by the British Graham Land Expedition under John Rymill, 1934–37, and was so named by the UK Antarctic Place-Names Committee in 1959 after the mackerel as it is one of the Fish Islands.
Mahaffey Glacier is a glacier flowing into the head of Morgan Inlet at the east end of Thurston Island, Antarctica. It was named by the Advisory Committee on Antarctic Names after J.S. Mahaffey, a Photographer's Mate in the Eastern Group of U.S. Navy Operation Highjump, which obtained aerial photographs of Thurston Island and adjacent coastal areas in 1946–47.
Savage Glacier is a glacier at the east end of Thurston Island, lying south of Tierney Peninsula and flowing east to Seraph Bay. The glacier was discovered on helicopter flights from the USS Glacier and Burton Island by personnel of the U.S. Navy Bellingshausen Sea Expedition in February 1960. The Advisory Committee on Antarctic Names named the glacier for Lieutenant John Savage, U.S. Navy, dental officer aboard the Glacier, who assisted in establishing geodetic control points in the area.
Salmon Island is the westernmost of the Fish Islands, lying off the west coast of Graham Land. Charted by the British Graham Land Expedition (BGLE) under Rymill, 1934-37. So named by the United Kingdom Antarctic Place-Names Committee (UK-APC) in 1959 because it is one of the Fish Islands.
Rambler Island is the largest of the Bragg Islands, lying in Crystal Sound about 7.5 nautical miles (14 km) north of Cape Rey, Graham Land. Mapped from surveys by Falkland Islands Dependencies Survey (FIDS) (1958–59). The name derives from association with Rambler Harbor which lies on the north side of the island.
Lagrange Peak is a conspicuous peak, 450 metres (1,500 ft) high, standing 5.5 nautical miles (10 km) northeast of Strath Point on the southeast coast of Brabant Island, in the Palmer Archipelago, Antarctica. A point on the coast just south of this peak was first charted and the name Lagrange applied by the Belgian Antarctic Expedition under Gerlache, 1897–99. On one of the photos published by the expedition, the name is applied to the southern tip of the island. To avoid confusion, the generic term has been altered and the name applied to this peak.
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.
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.
