Holme Bay
Gibbney Island is a small island on the west side of Holme Bay, off Mac. Robertson Land, Antarctica. It was mapped by Norwegian cartographers from air photos taken by the Lars Christensen Expedition, 1936–37, and named "Bryggeholmen" (the wharf island). It was renamed by the Antarctic Names Committee of Australia for L.F. Gibbney, officer in charge at Heard Island station in 1952.
