The Totten Glacier is a large glacier of around 64 km in length and up to 32 km in width in the East Antarctic Wilkesland . It first flows from the Antarctic ice sheet in a north-easterly direction and then flows north-west east of Cape Waldron in the form of an imposing glacier tongue on the Sabrina coast into the Southern Ocean .
The glacier was mapped using aerial photographs taken during Operation Highjump (1946–1947) led by the US polar explorer Richard Evelyn Byrd . The Advisory Committee on Antarctic Names named the glacier in 1955 and the glacier tongue in 1956 after George M. Totten (1816-1857), midshipman and cartographer on the USS Vincennes in the United States Exploring Expedition (1838-1842) headed by the American Polar explorer Charles Wilkes .
The Totten Glacier is the largest glacier in East Antarctica. He is showing signs of decline. A melting of the glacier would lead to a rise of the sea level of 3.5 m worldwide. In research from 2018 to 2019, large freshwater lakes were discovered under the glacier that could accelerate the melting of the glacier.
