Debutante Island is a narrow island located in the southernmost part of the Søstrene Islands. The island is mostly ice-covered except for a small rock outcrop and barely protrudes above the general level of the Publications Ice Shelf. It was mapped by Norwegian cartographers from aerial photographs taken during the Lars Christensen Expedition, 1936–37, and was named "Debutante" in 1952 by John H. Roscoe because the island is just beginning to "come out" from under its ice cover.[1]
