The Marshall Archipelago is an extensive group of large ice-covered islands within the Sulzberger Ice Shelf off Antarctica. Several of the islands were discovered and plotted by the Byrd Antarctic Expeditions (1928–30 and 1933–35) and by the United States Antarctic Service (1939–41), all led by Admiral Richard E. Byrd. The full extent of the archipelago was mapped by the United States Geological Survey from surveys and U.S. Navy air photos (1959–65). The name was proposed by Admiral Byrd for General of the Army George C. Marshall, who made financial contributions as a private individual and also, on the same basis, provided advisory assistance to the Byrd expedition of 1933–35.[1]
