Borge Bay (60°43′S 45°37′W / 60.717°S 45.617°W) is a large, irregularly-shaped bay that dominates the east side of Signy Island, in the South Orkney Islands of Antarctica. It was charted in 1912 by Norwegian whaling captain Petter Sorlle, and named for Captain Hans Borge of the Polynesia, who undertook additional mapping of the bay during the following year.[1] It was charted in more detail in 1927 and 1933 by Discovery Investigations personnel, who named many of its features.[2][3] It was surveyed further in 1947 by the Falkland Islands Dependencies Survey (FIDS), which named several other features.[4]
