Exciting change is on the way! Please join us at nsf.gov for the latest news on NSF-funded research. While the NSF Science360 page and daily newsletter have now been retired, there’s much happening at nsf.gov. You’ll find current research news on the homepage and much more to explore throughout the site. Best of all, we’ve begun to build a brand-new website that will bring together news, social media, multimedia and more in a way that offers visitors a rich, rewarding, user-friendly experience.

Want to continue to receive email updates on the latest NSF research news and multimedia content? On September 23rd we’ll begin sending those updates via GovDelivery. If you’d prefer not to receive them, please unsubscribe now from Science360 News and your email address will not be moved into the new system.

Thanks so much for being part of the NSF Science360 News Service community. We hope you’ll stay with us during this transition so that we can continue to share the many ways NSF-funded research is advancing knowledge that transforms our future.

Picture of the Day

Thwaites Glacier focus of international program

The National Science Foundation and the United Kingdom's National Environmental Research Council are the forces behind eight new initiatives in Antarctica to determine how quickly a massive glacier could collapse. GHOST -- Geophysical Habitat of Subglacial Thwaites -- will look at the sediment and bedrock underlying the Thwaites Glacier. The Thwaites Glacier is part of the West Antarctic Ice Sheet and flows into the Amundsen Sea in the southern South Pacific Ocean. It has a relatively small ice shelf, so most of the ice is supported by land, meaning that any ice from the glacier that enters the water will add to sea level rise. Ice shelves slow the progression of ice flowing into the oceans and protect the edge of the glacier from melting by ocean water. Researchers understand, in general, how glaciers move and ice shelves calve off, but they need to know the particulars of exactly what happens in this glacier. To find out, the researchers will use radar and seismic sensing to study the interface of the glacier and the rock and debris beneath. The Thwaites ice is a half-mile to a mile deep, so remote sensing, and particularly active sensing, are planned. For example, in active seismic sensing, sound is sent through the ice, and seismic sensors on the surface of the ice record the echo that returns. Once field data is collected, the researchers will model a variety of scenarios to see if Thwaites is likely to quickly run into the sea, causing more than 3 feet of sea level rise, or destabilize over longer times.
