Who / What
Thwaites Glacier is an unusually broad and vast Antarctic glacier located east of Mount Murphy on the Walgreen Coast of Marie Byrd Land. It is known for flowing rapidly into Pine Island Bay, part of the Amundsen Sea, with surface speeds exceeding 2 kilometres (1.2 mi) per year near its grounding line. The glacier is named in honor of the late American glaciologist Fredrik T. Thwaites.
Background & History
The glacier was first sighted by polar researchers in 1940, a critical early observation that highlighted its prominence. Detailed mapping was carried out between 1959 and 1966, enabling scientists to chart its extent and dynamics. In 1967, it received its official name, Thwaites Glacier, after Fredrik T. Thwaites, a respected contributor to glaciology.
Why Notable
Thwaites Glacier ranks among the most significant glacial systems in Antarctica, both in size and in its potential impact on global sea‑level rise. Its unusually high surface speeds near the grounding line make it a key focus for understanding ice‑mass balance and ice‑sheet dynamics. The glacier’s name preserves the legacy of Fredrik T. Thwaites and underscores its importance within polar research.
In the News
Current interest in Thwaites Glacier centers on its rapidly changing flow and the implications for global sea‑level rise. Recent observations have highlighted its extraordinary speed, drawing attention from scientists studying climate change and water‑cycle feedbacks in Antarctica. Monitoring this glacier remains essential for forecasting future sea‑level scenarios.
