Geophysical Sciences Professor Doug MacAyeal and Geophysical Sciences graduate student Grant Macdonald were recently interviewed about their recent research paper on supraglacial lakes. Understanding the role that supraglacial lakes play in the melting and thinning of glaciers, made famous by the disintegration of the Larsen B Ice Shelf in Antartctica in 2002, is essential for understanding the future of ice shelves in a warming climate.

Geophysical Sciences Professor Nicolas Dauphas co-authored a recently published article in Nature that sheds new light on the rate and manner of the emergence of land on Earth billions of years ago. Dauphas and his colleagues analyzed shale rocks from every continent for oxygen isotopes, which indicate the existence of precipitation across these land masses up to 3.5 billion years ago.

Associate Professor Elizabeth Moyer's research into the role that the southeast Asian monsoon plays in the broader global climate was the subject of a recent meeting of science teams in Italy. Her research reveals new details about how pollution and water from near the ground is transported to the stratosphere during the monsoon, for which she has been awarded a five-year, $5 million National Science Foundation grant to study high-altitude sub-visible cirrus clouds.
