Déjà Vu? Ocean Warmth Melted Ancient West Antarctic Ice Shelf
EOS News – Jan. 31
Scientists sailing on a research cruise in the Amundsen Sea, off the coast of western Antarctica, have found evidence of massive, ancient loss of an ice shelf in the region, resulting from contact with warmer seawater. Seafloor sediment cores the team collected in front of the current Cosgrove Ice Shelf indicate that relatively warm ocean water under-melted a vast ice shelf about 2000 years ago, they recently reported. This melting occurred despite cooling air temperatures and advance of neighboring ice shelves in the Antarctic Peninsula. The clues found in sediments deposited during the late Holocene suggest that an ocean mass that circles the southern polar region, known as Circumpolar Deep Water, flowed onto the continental shelf and underneath the Cosgrove Ice Shelf, eventually melting it. Today, the shrunken shelf covers an area nearly as large as the state of Rhode Island, but it was much larger before this melting event. “This circumpolar water isn’t like a hot tub. It’s only about 2°C warmer” than the surrounding ocean, said lead research author Rebecca Totten Minzoni, a paleoclimatologist from the University of Alabama in Tuscaloosa. Still, that’s enough to have a major impact on ice dynamics, she explained. This example of past ocean-driven melting causes concern for major glacial systems farther south, which could contribute significantly to sea level rise over the next hundred years.
The quest for cleaner fire: Why it’s time to rethink our favourite way to get warm – the globe and mail

‘Freedom’ gallery is open in downtown Tuscaloosa
Crimson White – Jan. 31
A new gallery in downtown Tuscaloosa is asking the question, “What is freedom?” The Paul R. Jones Gallery opened the new “Freedom?” gallery Jan. 23. The exhibit showcases pieces from Jones’s personal collection and is the end result of a two-year project that involved members of The University of Alabama’s Black Faculty and Staff Association and Dalila Scruggs, a curator from New York. “A sizable contingent of faculty has been involved in virtually every stage of the process – from choosing the theme and the works to be included to writing text for the catalog and planning class visits to the show,” said Stacy Morgan, BFSA member and associate professor of American studies.
