Fletcher's Ice Island

Fletcher's Ice Island or T-3 was an iceberg discovered by U.S. Air Force Colonel Joseph O. Fletcher. Between 1952 and 1978 it was used as a manned scientific research station that included huts, a power plant, and a runway for wheeled aircraft. The iceberg was a thick tabular sheet of glacial ice that drifted throughout the central Arctic Ocean in a clockwise direction. First inhabited in 1952 as an arctic weather report station, it was abandoned in 1954 but reinhabited on two subsequent occasions. The station was inhabited mainly by scientists along with a few military crewmen and was resupplied during its existence primarily by military planes operating from Barrow, Alaska. The iceberg was later occupied by the Naval Arctic Research Laboratory, and served as a base of operations for the Navy's arctic research projects such as sea bottom and ocean swell studies, seismographic activities, meteorological studies and other classified projects under the direction of the Department of Defense. Before the era of satellites, the research station on T-3 had been a valuable site for measurements of the atmosphere in the Arctic.
