Dolleman Island (Dolleman, isla)
Dolleman Island is a rounded, ice-covered island, 13 nmi long, lying 8 nmi east of Cape Boggs, off the east coast of Palmer Land. It was discovered in 1940 by members of East Base of the US Antarctic Service.
The island was named in honour of S-Sgt. Hendrik (Henry) Dolleman (1905-1990) of Manchester, New Hampshire, and born at 20-03-1905 in Deventer in the Netherlands. He was a retired career serviceman in the United States Air Force who served with Admiral Richard E. Byrd in Antarctica on the 1939 and 1955 Deep Freeze expeditions. Mr. Dolleman was also a sled dog trainer. In 1942, when Dolleman was stationed at Westover Field, Massachusetts, he won the Soldier's Medal with an oak leaf cluster for his participation in two polar rescue missions.
The British Antarctic Survey (BAS) has used Dolleman Island as an ice core drilling site in 1976, 1986 and 1993. The main findings from these cores are related to the migration of MSA within the ice (Pasteur and Mulvaney, 2000) and the identification of past atmospheric circulation change signals in the core (Peel and Mulvaney, 1992; Russell et al., 2006).
More information on Dolleman Island and its namesake may be found in the book Antarctic Command by Captain Finn Ronne, U.S.N.R. (Indianapolis: Bobbs-Merrill Co., first print edition, 1961).

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.
