Halfway Island is an island lying 4.6 kilometres (2.5 nmi) northwest of Litchfield Island, off the southwest coast of Anvers Island in the Palmer Archipelago. It was surveyed by the British Naval Hydrographic Survey Unit in 1956–1957. The name arose because the island lies halfway between Arthur Harbor and Cape Monaco, a route frequently traveled by boat by members of the Falkland Islands Dependencies Survey (FIDS) at the Arthur Harbor station.

Anvers Island high, mountainous island 61 km (38 miles) long, outside Antarctica

Anvers Island or Antwerp Island or Antwerpen Island or Isla Amberes is a high, mountainous island 61 km long, the largest in the Palmer Archipelago of Antarctica. It was discovered by John Biscoe in 1832 and named in 1898 by the Belgian Antarctic Expedition under Adrien de Gerlache after the province of Antwerp in Belgium. It lies south-west of Brabant Island at the south-western end of the group. The south-western coastline of the island forms part of the Southwest Anvers Island and Palmer Basin Antarctic Specially Managed Area. Cormorant Island, an Important Bird Area, lies 1 km off the south coast.

Palmer Archipelago Group of islands off the northwestern coast of the Antarctic Peninsula

Palmer Archipelago, also known as Antarctic Archipelago, Archipiélago Palmer, Antarktiske Arkipel or Palmer Inseln, is a group of islands off the northwestern coast of the Antarctic Peninsula. It extends from Tower Island in the north to Anvers Island in the south. It is separated by the Gerlache and Bismarck straits from the Antarctic Peninsula and Wilhelm Archipelago, respectively.

Cormorant Island island of Antarctica

Cormorant Island is a 10 ha island lying in Bismarck Strait 1 km south of Anvers Island, 4 km (2.5 mi) east-south-east of Bonaparte Point, in the Palmer Archipelago of Antarctica. It lies some 5 km to the south-east of the United States' Palmer Station in Arthur Harbour on Anvers Island. It was shown on an Argentine government chart of 1954, but not named. It was named by the United Kingdom Antarctic Place-names Committee (UK-APC) in 1958 because of the large number of cormorants (shags) seen there.

Hermit Island (Antarctic)

Hermit Island is an island nearly 2 kilometres (1 nmi) long, lying 3 kilometres (1.5 nmi) southeast of Bonaparte Point, off the southwest coast of Anvers Island in the Palmer Archipelago. So named by the United Kingdom Antarctic Place-names Committee (UK-APC) in 1958 because a member of the Falkland Islands Dependencies Survey (FIDS) at the Arthur Harbor station spent some time on this island alone in January 1957, making survey observations.

Arthur Harbour

Arthur Harbour is a small harbour entered between Bonaparte Point and Amsler Island on the south-west coast of Anvers Island in the Palmer Archipelago of Antarctica.

Janus Island

Janus Island is a rocky island 370 m (0.2 nmi) long, lying 1 km (0.5 nmi) south of Litchfield Island, off the southwest coast of Anvers Island in the Palmer Archipelago. Janus Island is the southernmost of the islands on the west side of the entrance to Arthur Harbor. Janus Island was named by the United Kingdom Antarctic Place-names Committee (UK-APC) following survey by the Falkland Islands Dependencies Survey (FIDS) in 1955. The name Janus Island, for the ancient Roman deity Janus who was guardian of gates, arose because of the position of the island at the entrance to Arthur Harbor.

Laggard Island

Laggard Island is a rocky island lying 3.7 km (2 nmi) southeast of Bonaparte Point, off the southwest coast of Anvers Island in the Palmer Archipelago. Laggard Island was named by the United Kingdom Antarctic Place-names Committee (UK-APC) following a 1955 survey by the Falkland Islands Dependencies Survey (FIDS). The name arose from the island's position on the eastern fringe of the islands in the vicinity of Arthur Harbor.

Litchfield Island island in Antarctica

Litchfield Island is a rocky island 0.9 kilometres (0.5 nmi) long and rising to 50 m (164 ft), lying in Arthur Harbour, 0.9 kilometres (0.5 nmi) south of Norsel Point, off the south-west coast of Anvers Island in the Palmer Archipelago of Antarctica.

Outcast Islands in the Palmer Archipelago of Antarctica

The Outcast Islands are two small islands, nearly 0.9 km (0.5 nmi) apart, and a number of surrounding rocks lying 3.7 km (2 nmi) southwest of Bonaparte Point, off the southwest coast of Anvers Island in the Palmer Archipelago of Antarctica. The Outcast Islands were named by the United Kingdom Antarctic Place-names Committee (UK-APC) following a survey in 1955 by the Falkland Islands Dependencies Survey (FIDS). The name arose because of their isolated position some distance from the other islands in the vicinity of Arthur Harbor.

Torgersen Island

Torgersen Island is a small rocky island lying just east of Litchfield Island in the entrance to Arthur Harbour, off the south-west coast of Anvers Island in the Palmer Archipelago of Antarctica. It was surveyed by the Falkland Islands Dependencies Survey in 1955 and named by the UK-APC for Torstein Torgersen, first mate of the Harbor in late February 1955, preceding the vessel Norsel in one of the ship's boats and making soundings.

Trinity Island island

Trinity Island or Île de la Trinité or Isla Trinidad is an island 24 km (15 mi) long and 10 km (6 mi) wide in the northern part of the Palmer Archipelago, Antarctica. It lies 37 km (23 mi) east of Hoseason Island,72.6 km (45 mi) south of Deception Island in the South Shetland Islands, and 10.3 km (6 mi) north-northwest of Cape Andreas on the Antarctic Peninsula. The island was named by Otto Nordenskiöld, leader of the 1901-1904 Swedish Antarctic Expedition (SAE) in commemoration of Edward Bransfield's "Trinity Land" of 1820.

Tripod Island

Tripod Island is a small island which lies close south of the west extremity of Eta Island and marks the north side of the western entrance to Andersen Harbor in the Melchior Islands, Palmer Archipelago. The name was probably given by DI personnel who roughly surveyed the island in 1927. The island was resurveyed by Argentine expeditions in 1942, 1943 and 1948.

Pabellón Island

Pabellón Island is the southernmost of two islands which lie close off the north tip of Omega Island and mark the south side of the western entrance to Andersen Harbor in the Melchior Islands, Palmer Archipelago. The island was roughly surveyed by DI personnel in 1927 and named by the Argentine expedition during a survey of these islands in 1946–47. They erected a mast on this island from which they flew the Argentine national colors (pabellón).

Melchior Islands group of many low, ice-covered islands

The Melchior Islands are a group of many low, ice-covered islands lying near the center of Dallmann Bay in the Palmer Archipelago, Antarctica. They were first seen but left unnamed by a German expedition under Eduard Dallmann, 1873–74. The islands were resighted and roughly charted by the Third French Antarctic Expedition under Jean-Baptiste Charcot, 1903–05. Charcot named what he believed to be the large easternmost island in the group "Île Melchior" after Vice Admiral Jules Melchior of the French Navy, but later surveys proved Charcot's Île Melchior to be two islands, now called Eta Island and Omega Island. The name Melchior Islands has since become established for the whole island group now described, of which Eta Island and Omega Island form the eastern part, while the Sigma Islands mark the northern limit of the islands. The group was roughly surveyed in 1927 by Discovery Investigations personnel in the RRS Discovery, and was resurveyed by Argentine expeditions in 1942 and 1943, and again in 1948.

Bills Island island

Bills Island is an island in Antarctica. It lies northeast of Goudier Island in the harbor of Port Lockroy, in the Palmer Archipelago. It was discovered and charted by the French Antarctic Expedition, 1903–05, under Jean-Baptiste Charcot. The name appears on a chart based on a 1927 Discovery Investigations survey, but may reflect an earlier naming.

Wylie Bay is a bay 4 nautical miles (7 km) wide, lying between Cape Monaco and Norsel Point on the southwest coast of Anvers Island, in the Palmer Archipelago. First charted by the French Antarctic Expedition under Charcot, 1903–1905, it was named by the United Kingdom Antarctic Place-Names Committee (UK-APC) in 1959 for John P. Wylie, Falkland Islands Dependencies Survey (FIDS) surveyor at Arthur Harbor in 1956 and 1957.

DHainaut Island

D'Hainaut Island is a small island lying in Mikkelsen Harbor, Trinity Island, in the Palmer Archipelago. It was charted by the French Antarctic Expedition, 1908–10, under Jean-Baptiste Charcot, and named by the sixth Chilean Antarctic Expedition (1952) for Lieutenant Ladislao D'Hainaut.

Gerlache Island

Gerlache Island is the largest of the Rosenthal Islands lying off Gerlache Point on the west coast of Anvers Island, in the Palmer Archipelago of Antarctica. It was first roughly charted and named "Pointe de Gerlache" by the French Antarctic Expedition, 1903–05, under Jean-Baptiste Charcot, for Lieutenant Adrien de Gerlache. As a result of surveys by the Falkland Islands Dependencies Survey in 1956–58, this island is considered to be the feature named by Charcot; there is no prominent point in this vicinity which would be visible from seaward.

Goudier Island is a small island with an appearance of bare, polished rock, lying 0.05 nautical miles (0.1 km) north of Jougla Point in the harbor of Port Lockroy, Wiencke Island, in the Palmer Archipelago. It was discovered by the French Antarctic Expedition, 1903–05, under Jean-Baptiste Charcot, and named after E. Goudier, chief engineer of the expedition ship Français.

Tetrad Islands

Tetrad Islands is a group of small islands lying southeast of Borge Point at Mikkelsen Harbor on Trinity Island in the Palmer Archipelago. They were shown on a 1952 Argentine government chart. The name given by the United Kingdom Antarctic Place-Names Committee (UK-APC) in 1960 is descriptive; there are four islands in the group.
