Eagle Island (63°40′S 57°29′W / 63.667°S 57.483°W) is an island 5 nautical miles (9.3 km; 5.8 mi) long and 4 nautical miles (7.4 km; 4.6 mi) wide, rising to 560 metres (1,840 ft) on the NE side. It is the largest island in the archipelago which lies between Trinity Peninsula and Vega Island.[1] Eagle Island is separated from the Antarctic mainland by the 1.77 km wide Aripleri Passage. It is volcanic in origin, having been
Location
Eagle Island is in Graham Land, to the southeast of the Trinity Peninsula, which is the tip of the Antarctic Peninsula.
Exploration and name
Eagle Island was probably first seen by a party under Johan Gunnar Andersson of the Swedish Antarctic Expedition (SwedAE), 1901-04. Eagle Island was charted in 1945 by the
Melting events
During the Southern Hemisphere summer of 2019-2020 three melting events occurred on Trinity peninsula, in November 2019, January 2020, and particularly February 6–11, 2020, during which 106 millimeters of snow melted, forming melt ponds on Eagle Island.[4] The nine day heatwave in early February 2020 melted about 20% of the island's snow cover.[5]
Features
The Horn
63°39′S 57°34′W / 63.650°S 57.567°W. A hill, 220 metres (720 ft) high, with a sheer cliff of reddish rock on its west side, surmounting the northwest point of Eagle Island. Surveyed and named descriptively by the FIDS in 1945.[6]
Scree Peak
63°38′S 57°27′W / 63.633°S 57.450°W. A conspicuous, flat-topped peak with talus-covered slopes, 560 metres (1,840 ft) high, standing at the northeast end of Eagle Island in Prince Gustav Channel. Discovered by the FIDS and so named following their 1945 survey. The name is descriptive of the slopes of the peak.[7]
Nearby islands
Tongue Rocks
63°38′S 57°21′W / 63.633°S 57.350°W. A small ice-free volcanic rocks lying between Eagle Island and Beak Island, off Trinity Peninsula. Named by UK Antarctic Place-Names Committee (UK-APC) in association with Eagle and Beak Islands.[8]
Beak Island
63°37′S 57°18′W / 63.617°S 57.300°W. An arc-shaped island, 4 nautical miles (7.4 km; 4.6 mi) long and 360 metres (1,180 ft) high high, lying 0.5 nautical miles (0.93 km; 0.58 mi) northeast of Eagle Island in the northeast part of Prince Gustav Channel. Probably first seen in 1902-03 by members of the SwedAE under Nordenskjold. The FIDS surveyed Beak Island in 1945 and so named it because of its shape and relative position to nearby Tail and Eagle Islands.[9]
Tail Island
63°40′S 57°37′W / 63.667°S 57.617°W. A circular island 1.25 nautical miles (2.32 km; 1.44 mi) in diameter and 130 metres (430 ft) high high, lying midway between Egg Island and Eagle Island in the northeast part of Prince Gustav Channel. Islands in this area were first seen by a party under J. Gunnar Andersson of the SwedAE, 1901-04. Tail Island was charted by the FIDS in 1945, and so named by them because of its relative position to Eagle and Beak Islands.[10]
Egg Island
63°41′S 57°42′W / 63.683°S 57.700°W. A circular island 1.5 nautical miles (2.8 km; 1.7 mi) in diameter and 310 metres (1,020 ft) high, lying 1 nautical mile (1.9 km; 1.2 mi) west of Tail Island in the northeast part of Prince Gustav Channel. Probably first seen by a party under J. Gunnar Andersson of the SwedAE, 1901-04. It was charted in 1945 by the FIDS, who so named it because of its relative position to Tail, Eagle and Beak Islands.[11]
Corry Island
63°43′S 57°31′W / 63.717°S 57.517°W. An island 2 nautical miles (3.7 km; 2.3 mi) long and 510 metres (1,670 ft) high high, lying off the south coast of Trinity Peninsula between Vega Island and Eagle Island. This is believed to be the feature sighted by a British expedition under
Vortex Island
63°44'S, 57°38'W
An island 0.5 nautical miles (0.93 km; 0.58 mi) long and 245 metres (804 ft) high, lying in the northeast part of Prince Gustav Channel about 2 nautical miles (3.7 km; 2.3 mi) west-southwest of Corry Island. Islands in this area were first seen by a party under J. Gunnar Andersson of the SwedAE, 1901-04. Vortex Island was first charted by the FIDS in August 1945. The FIDS survey party was forced to lie idle there by a whirlwind snowstorm, thus suggesting the name.[13]
Devil Island
63°48′S 57°17′W / 63.800°S 57.283°W. A narrow island 1 nautical mile (1.9 km; 1.2 mi) long with a low summit on each end, lying in the center of a small bay 1 nautical mile (1.9 km; 1.2 mi) southeast of
