. Named after Terence J. Hughes of the Department of Geological Sciences and Institute of Quaternary Studies, University of Maine, Orono, who made an intensive study of the Byrd Glacier, 1978–79, entailing photogrammetric determination of the elevation of the ice surface and its velocity, radio-echo sounding from LC-130 aircraft, and ground survey from fixed stations close to Byrd Glacier and moving stations on the glacier

Glacier

A glacier is a large persistent body of ice that forms where the accumulation of snow exceeds its ablation over many years, often centuries. At least 0.1 km² in area and 50 m thick, but often much larger, a glacier slowly deforms and flows due to stresses induced by its weight...
