The Amundsen Sea is an arm of the
Southern Oceanoff Marie Byrd Landin western Antarctica. It is bounded by Thurston Islandto the east and Cape Dartto the west. Named for the Norwegian polar explorer Roald Amundsenby the Norwegian expedition of 1928-29, under Captain Nils Larsen, while exploring this area in February, 1929.gnis|id=378|type=antarid]
The sea is mostly ice-covered, and the
Thwaites Ice Tongueprotrudes into it. The ice-covered area of the sea, averaging about 3 km (2 miles) in thickness and roughly the size of the state of Texas, is called the Amundsen Sea Embayment; it forms one of the three major ice drainage basins of the West Antarctic Ice Sheet, the others being the Ross SeaEmbayment and the Weddell SeaEmbayment. In March 2007, scientists studying the ASE through satellite and airborne surveys announced a significant thinning of the ASE, due to shifts in wind patterns that allow warmer waters to flow beneath the ice sheet.

Sea level rise — is an increase in sea level. Multiple complex factors may influence this change. Sea level has risen about 130 meters (400 ft) since the peak of the last ice age about 18,000 years ago. Most of the rise occurred before 6,000 years ago. From 3,000 … Wikipedia
