Cuverville Island, December 2014
|Administered under the Antarctic Treaty System|
Cuverville Island or Île de Cavelier de Cuverville is a dark, rocky island lying in Errera Channel between Arctowski Peninsula and the northern part of Rongé Island, off the west coast of Graham Land in Antarctica. Cuverville Island was discovered by the Belgian Antarctic Expedition (1897–1899) under Adrien de Gerlache, who named it for J.M.A. Cavelier de Cuverville (1834–1912), a vice admiral of the French Navy.
The bedrock on the island is metavolcanic rock with white feldspar crystals, with some volcanic breccia. The metamorphism was of a low grade variety.
Important Bird Area
The island has been identified as an Important Bird Area (IBA) by BirdLife International because it supports a breeding colony of about 6500 pairs of gentoo penguins, the largest for this species on the Antarctic Peninsula. Other birds nesting at the site include southern giant petrels and Antarctic shags.
