When oceanographer Bess Ward was granted research time aboard the R/V Sally Ride during the middle of the spring semester, she had to figure out how to teach GEO 428, “Biological Oceanography,” from the Pacific Ocean.  She created a teaching schedule that used student presentations, a series of guest lecturers, and her first teaching assistant for this course, who showed the students videos that Ward created and uploaded from the ship as it sampled the waters off the coast of Mexico.
Imagine an enormous volcano erupting in the Pacific Northwest, pouring lava across Washington, Oregon and Idaho. Before now, most geologists believed that it took almost 2 million years to erupt all that lava, collectively known as “the Columbia River flood basalts.” But Princeton researchers are publishing findings today that show it happened more than twice as fast as previously believed.
On September 5, 2018, The Blavatnik Family Foundation and the New York Academy of Sciences announced Postdoctoral Research Associate Lucia Gualtieri as a finalists in their 2018 Blavatnik Regional Award for Young Scientists in the category of “Physical Sciences & Engineering.”
With millions of coastal residents either on the move or hunkering down in place, Hurricane Florence surges toward North Carolina, tracing an unusual path that could lead to tremendous destruction. Gabriel Vecchi, a climate scientist at Geosciences, noted that while many scientists are wary of drawing firm links between any particular storm and climate change, a rising sea level adds to the destructiveness of storm surges, and a warming atmosphere holds more moisture, leading to more rain.
The Department of Geosciences congratulates the 10 Ph.D. candidates who are the newest members of PEI's Princeton Climate and Energy Scholars (PECS) program. Xuyuan (Ellen) Ai, Katja Luxem and Jack Murphy from our department are among the 10 announced.
A possible Category 6? A new study shows that we have a lot to worry about when it comes to changing hurricanes as the planet warms. "It’s what you expect if you have a shift toward more intense storms, is that you’ll start seeing intensities you haven't seen before,” said atmospheric scientist Gabriel Vecchi.

A Princeton geologist Gerta Keller has endured decades of ridicule for arguing that the fifth extinction was caused not by an asteroid but by a series of colossal volcanic eruptions. But she’s reopened that debate.
On April 12, 2018, Princeton Prof. Frederik J. Simons and graduate students Joel D. Simon and Alex Burky, along with their international collaborators, boarded the Fukae Maru for a two-day training cruise. The goal of the cruise, led by Kobe University Prof. Hiroko Sugioka and JAMSTEC scientist Dr. Masayuki Obayashi, was to learn instrument deployment and data recovery procedures for the newest-generation MERMAID float.
The oceans are the planet’s most important depository for atmospheric carbon dioxide on time scales of decades to millenia. But the process of locking away greenhouse gas is weakened by activity of the Southern Ocean, so an increase in its activity could explain the mysterious warmth of the past 11,000 years, an international team of researchers reports.
