Wintering
Ernst Sorge was a member of Alfred Wegener's expedition. Together with Johannes Georgi he stayed in Eismitte from July 1930 to August 1931. Fritz Loewe stayed from October 1930 to May 1931. Sorge hand-dug a 15 m deep pit adjacent to his subterranean snow cave, which served as living quarters during the seven-month-long overwintering. Sorge systematically and quantitatively studied the near-surface snow/firn strata from inside his pit. After examination of the structural features and measurement of continuous density and other physical properties within the pit profile, he determined the characteristics of the individual limits of annual snow accumulation. This research validated the feasibility of measuring the preserved annual snow accumulation cycles, like measuring frozen precipitation in a rain gauge.[3]

Climate
Eismitte is one of the coldest locations in the Northern Hemisphere, with an annual mean temperature of −30.0 °C (−22 °F) having been recorded during the period of the expedition that established it. Eismitte has a polar ice cap climate. The weather station was run for approximately one year; the weather record thus is very sparse. The Summit Camp station slightly to the north has a similar climate with a much longer period of record.
