Antartica Sea

The Antarctic Ocean area covered by ice has shrunk to a record low, exposing the thicker ice shelves buttressing Antarctica's ground ice sheet to waves and warmer temperatures, scientists reported Thursday.

A team of British researchers used "ice penetrating radar" to map the sub glacial landscape, which they say adds a key piece of evidence to understand the frozen continent's past, present and future behavior. The researchers discovered three valleys linking Antarctica's two major parts: the Western Antarctic Ice Sheet and the far bigger Eastern Ant...

Climate changes that began about 17,700 years ago included a sudden poleward shift in westerly winds encircling Antarctica with corresponding changes in sea ice extent, ocean circulation, and ventilation of the deep ocean.
