The Department of Geosciences and Princeton University congratulates Jahnavi N. Punekar on successfully defending her Ph.D. thesis.
Last week, NASA scientists published a study in the "Journal of Glaciology" claiming that the continent of Antarctica is gaining ice, rather than losing it, to the tune of 82 gigatons per year from 2003 to 2008. Geoscientist Christopher Harig of Princeton University defends GRACE measurements and the finding that Antarctica is losing mass, and that a key part of the difference between his research and the new study involves how researchers handle “glacial isostatic adjustment” or GIA.
A collection of studies examined extreme weather events last year, to look for signs that climate change was a cause or contributor. The papers are part of a broader effort to recognize the effects of climate change as the world warms.
The interplay of all the different kinds of warming going on in the Pacific at the moment can be difficult to sort out. Geosciences Lect. Gabriel Vecchi likened the challenge to the board game Clue: “There’s all these suspects, and we have them all in the room right now,” he said. “The key is to go and systematically figure out who was where and when, so we can exclude people or phenomena.”
In 2011, an influx of remote sensing data from satellites scanning the African savannas revealed a mystery: these rolling grasslands, with their heavy rainfalls and spells of drought, were home to significantly fewer trees than researchers had previously expected given the biome’s high annual precipitation. In fact, the 2011 study found that the more instances of heavy rainfall a savanna received, the fewer trees it had.
AOS Postdoctoral Research Fellow Sarah Kapnick will receive the 2015 Cryosphere Early Career Award at the 2015 American Geophysical Union Fall Meeting, to be held 14–18 December in San Francisco, Calif. The award is for "a significant contribution to cryospheric science and technology. The Department of Geosciences congratulates Dr. Kapnick on receiving this significant recognition.
The Department of Geosciences and Princeton University congratulates Blake C. Dyer on successfully defending his Ph.D. thesis.
The Department of Geosciences and Princeton University congratulates Xuefeng (Nick) Peng on successfully defending his Ph.D. thesis.
Many studies predict that future sea-level rise along the U.S. Atlantic and Gulf coasts will increase flooding. Others suggest that the human-caused warming driving this rise will also boost the intensity and frequency of big coastal storms. Up to now, though, these two hazards have been assessed mostly in isolation from each other.
The Department of Geosciences congratulates Graduate Student Yanhua O. Yuan *16, from the Simons Research Group, on being awarded the Charlotte Elizabeth Procter Honorific Fellowship by the Princeton University Graduate School.
