The Bugge Islands (also Ruth Bugge Islands ) consist of three ice-covered islands in Marguerite Bay off the Fallières coast of Graham Land on the Antarctic Peninsula . They lie in front of the now- defunct Wordie Ice Shelf and between 7 and 20 kilometers northwest of Mount Guernsey .
Islands
The archipelago consists of three islands:
- Ramírez Island or Isla Eleuterio Ramirez ( 69 ° 9 ′ S , 68 ° 27 ′ W ), northernmost island
- Aldea Island or Isla Aldea ( 69 ° 12 ′ S , 68 ° 30 ′ W ), middle island
- Landrum Island or Isla Latorre ( 69 ° 14 ′ S , 68 ° 17 ′ W ), southernmost island
The highest of the islands is 366 m high. There are several islets and rocks on the north, south-east, and south-south-west sides.
According to Finn Ronne's 1947 report by the Ronne Antarctic Research Expedition , the islands stretch for almost 10 kilometers in a northeasterly direction. The largest of the islands is about 2–3 kilometers long. The expedition found the islands covered by a blanket of snow about 30 meters high, with bare rocks on the shore.
history
The islands were first discovered from the air and photographed by the British Graham Land Expedition (BGLE) in 1936 . They were later roughly mapped using these aerial photographs. In 1947 the group of islands was sighted by the Ronne Antarctic Research Expedition (RARE) under Finn Ronne from the ship "M / V Port of Beaumont, Texas" (formerly USS ATA 215). Ronne named her after his niece Ruth Bugge, who supplied the expedition with woolen clothing from Norway .
Later that year, the islands were also explored by the first Chilean Antarctic expedition.
Data for the years 1948–1958 show that the front of the Wordie Ice Shelf at that time still extended to the Bugge Islands. Since then, however, the ice shelf has shrunk.
