UNIVERSITY PARK, Pa. — 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. Penn State is part of two of these projects, GHOST and MELT.

GHOST — Geophysical Habitat of Subglacial Thwaites — will look at the sediment and bedrock underlying the Thwaites glacier.

"The future picture of what the glacier will do is dependent on the bed," said Sridhar Anandakrishnan, professor of geosciences, Penn State and principal investigator for this five-year, $4 million grant. "We need to know if it is sediment or hard rock and whether it is rough or smooth. All these details make it easier to understand what the glacier's response will be over decades and centuries."  More
