Marshall Archipelago (Marshall Archipelago)
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.
* Benton Island (-77.06667°N, -147.88333°W) is an island 4 nmi in length, lying northwest of Nolan Island and 5 nmi west of Przybyszewski Island in the Marshall Archipelago.
* Cronenwett Island (-77°N, -150°W) is an island 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 (°N, °W) is an island 7 nmi in length and 1 nmi in width. The island lies 13 nmi southwest of Steventon Island within the Marshall Archipelago.
* Hannah Island (-76.65°N, -148.8°W) is an island lying between Hutchinson Island and Guest Peninsula lying within the Marshall Archipelago.
* Hutchinson Island (-76.78333°N, -148.88333°W) is an island 15 nmi long, lying 10 nmi east of Vollmer Island.
* Kramer Island (°N, °W) is an island 2 nmi in length and is situated between Nolan Island and Court Ridge in the Marshall Archipelago.
* Madden Island (-77.45°N, -149.05°W) is an island 4 nmi in length and is located between Moody Island and Grinder Island in the Marshall Archipelago.
* Orr Island (°N, °W) is an island 5 nmi in length and lies 3 nmi southwest of Grinder Island in the Marshall Archipelago.
* Przybyszewski Island (-76.96667°N, -148.75°W) is an island 12 nmi in length and lies 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.

Country - Antarctica
Antarctica is Earth's southernmost and least-populated continent. Situated almost entirely south of the Antarctic Circle and surrounded by the Southern Ocean (also known as the Antarctic Ocean), it contains the geographic South Pole. Antarctica is the fifth-largest continent, being about 40% larger than Europe, and has an area of 14200000 km2. Most of Antarctica is covered by the Antarctic ice sheet, with an average thickness of 1.9 km.
Antarctica is, on average, the coldest, driest, and windiest of the continents, and it has the highest average elevation. It is mainly a polar desert, with annual precipitation of over 200 mm along the coast and far less inland. About 70% of the world's freshwater reserves are frozen in Antarctica, which, if melted, would raise global sea levels by almost 60 m. Antarctica holds the record for the lowest measured temperature on Earth, −89.2 C. The coastal regions can reach temperatures over 10 C in summer. Native species of animals include mites, nematodes, penguins, seals and tardigrades. Where vegetation occurs, it is mostly in the form of lichen or moss.
