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 '''[[king penguin]]''' is a large species of [[penguin]], second only to the [[emperor penguin]] in size. King penguins eat small fish, mainly lanternfish, and squid. They are less reliant on [[krill]] and other crustaceans than most [[Southern Ocean]] predators. On foraging trips king penguins repeatedly dive to over 100 meters (300 ft), and have been recorded at depths greater than 300 meters (1,000 ft). King penguins breed on the subantarctic islands at the northern reaches of [[Antarctica]], South Georgia, and other temperate islands of the region. King penguins do not live or breed in [[Westarctica]].


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.

King Penguin Chick.jpg

The king penguin is a large species of penguin, second only to the emperor penguin in size. King penguins eat small fish, mainly lanternfish, and squid. They are less reliant on krill and other crustaceans than most Southern Ocean predators. On foraging trips king penguins repeatedly dive to over 100 meters (300 ft), and have been recorded at depths greater than 300 meters (1,000 ft). King penguins breed on the subantarctic islands at the northern reaches of Antarctica, South Georgia, and other temperate islands of the region. King penguins do not live or breed in Westarctica.
