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]

Islands

• Benton Island (77°4′S 147°53′W) is an island 7.4 kilometres (4 nmi) in length, lying northwest of Nolan Island and 9.3 kilometres (5 nmi) west of Przybyszewski Island in the Marshall Archipelago.

• Cronenwett Island (77°0′S 150°0′W) is an island 37 kilometres (20 nmi) in length making it the longest island in the archipelago. The island lies between Vollmer Island and Steventon Island in the Marshall Archipelago. Although the island is near Vollmer Island, Vollmer Island is not actually considered one of the islands of the Marshall Archipelago.

• Grinder Island (77°34′S 149°20′W) is an island 13 kilometres (7 nmi) in length and 1.9 kilometres (1 nmi) in width. The island lies 24 kilometres (13 nmi) southwest of Steventon Island within the Marshall Archipelago.

• Hannah Island (76°39′S 148°48′W) is an island lying between Hutchinson Island and Guest Peninsula lying within the Marshall Archipelago.

• Hutchinson Island (76°47′S 148°53′W) is an island 28 kilometres (15 nmi) long, lying 19 kilometres (10 nmi) east of Vollmer Island.

• Kramer Island (77°14′S 147°10′W) is an island 3.7 kilometres (2 nmi) in length and is situated between Nolan Island and Court Ridge in the Marshall Archipelago.

• Madden Island (77°27′S 149°3′W) is an island 7.4 kilometres (4 nmi) in length and is located between Moody Island and Grinder Island in the Marshall Archipelago.

• Orr Island (77°38′S 149°36′W) is an island 5 nautical miles (9.3 km; 5.8 mi) in length and lies 5.6 kilometres (3 nmi) southwest of Grinder Island in the Marshall Archipelago.

• Przybyszewski Island (76°58′S 148°45′W) is an island 22 kilometres (12 nmi) in length and lies 5.6 kilometres (3 nmi) east of Cronenwett Island in the Marshall Archipelago. Barela Rock appears to be a rock formation of interest, located in the southern portion of Przybyszewski Island.

• Thode Island (77°2′S 148°3′W) is an island 1.9 kilometres (1 nmi) northwest of Benton Island and 9.3 kilometres (5 nmi) east of Przybyszewski Island in the Marshall Archipelago.
