詳細説明

Robert Island is located in the central South Shetland Islands between Nelson Island and Greenwich Island. The island is approximately 18km long and 13km wide with an area of 132 square kilometers. Its most notable feature is the Coppermine Peninsula on the western coast, which consists of a perched strandflat - an ice-free area with raised marine terraces indicating past sea levels. The island was likely named by Captain Richard Fildes after his brig Robert during his 1821-22 sealing expedition. Historical Russian name: Polotsk Island.
