The '''Thwaites Glacier''' (75°30′S 106°45′W), including the '''Thwaites Ice Tongue''', is an unusually broad and fast Antarctic [[glacier]] flowing into [[Pine Island Bay]], part of the [[Amundsen Sea]], east of [[Mount Murphy]], on the [[Walgreen Coast]] of [[Westarctica]]. Its surface speeds exceed 2 km/yr near its grounding line, and its fastest flowing grounded ice is centered between 50 and 100 km east of [[Mount Murphy]]. It was named after Fredrik T. Thwaites, a glacial geologist, geomorphologist and professor emeritus at the University of Wisconsin–Madison.
The '''[[Hobbs Coast]]''' is the portion of the coast of [[Westarctica]] extending from [[Cape Burks]] to a point on the coast opposite eastern [[Dean Island]], at 74°42′S 127°05′W, or between the [[Ruppert Coast]] in the west and the [[Bakutis Coast]] in the east. It stretches from 136°50′W to 127°35′.


Along with the [[Pine Island Glacier]], the Thwaites Ice Tongue has been described as part of the "weak underbelly" of the [[West Antarctic Ice Sheet]], due to its apparent vulnerability to significant retreat. This hypothesis is based on both theoretical studies of the stability of marine ice sheets and recent observations of large changes on both of these glaciers. In recent years, the flow of both of these glaciers have accelerated, their surfaces lowered, and the grounding lines retreated.
The coast was discovered by the US [[Antarctica|Antarctic]] Service (1939–41) mapped by the United States Geological Survey from ground surveys and U.S. Navy air photos, 1959–65. The Hobbs Coast was named for Professor William H. Hobbs of the University of Michigan, a glaciologist specializing in polar geography and history.

Hobbs Coast Mountains-NANA.jpg

The Hobbs Coast is the portion of the coast of Westarctica extending from Cape Burks to a point on the coast opposite eastern Dean Island, at 74°42′S 127°05′W, or between the Ruppert Coast in the west and the Bakutis Coast in the east. It stretches from 136°50′W to 127°35′.

The coast was discovered by the US Antarctic Service (1939–41) mapped by the United States Geological Survey from ground surveys and U.S. Navy air photos, 1959–65. The Hobbs Coast was named for Professor William H. Hobbs of the University of Michigan, a glaciologist specializing in polar geography and history.
