Faculty Spotlight

Professor John A. Higgins

Title: Associate Professor of Geosciences
Research Areas:

Professor John Higgins' primary research interest is the evolution of the carbon cycle and the global climate system over Earth history.  One focus has been on processes that control the chemical composition of seawater, and how those processes have changed on geologic timescales.  Another is how on the chemistry of carbonate sediments is affected by processes that occur post-deposition.  These include early diagenetic recrystallization, dolomitization and hydrothermal alteration.  The tools Prof. Higgins has employed to study these include numerical models of chemical and isotopic biogeochemical cycles, as well as analysis of traditional stable isotopes of oxygen and carbon, and new isotope systems such as magnesium, calcium, and potassium.

Have you ever seen an icebreaker roll on the waves? Neither have I, at least from the outside. But after almost two weeks at sea, we have certainly felt it from within.

Animals and plants are not the only things that form fossils. Tsunamis—the huge waves created by some submarine earthquakes—do so, too. They might reasonably wonder when the next big wave will arrive—as might residents of other earthquake-prone coastlines around the world. Alumnus Dr. Harvey M. Kelsey, III '71, of Humboldt State University, in...

In response to NASA scientist James Hansen's paper, climate scientist Michael Oppenheimer of Princeton University affirmed: "If we cook the planet long enough at about two degrees warming, there is likely to be a staggering amount of sea level rise. Key questions are when would greenhouse-gas emissions lock in this sea level rise and how fast...

This summer, Princeton undergraduate students are gaining new perspectives and opportunities through internships in a variety of fields in more than 50 countries through the University's International Internship Program (IIP). GEO Undergrad Alyson Beveridge '16 describes her internship teaching English at The Tushita Foundation in Jaipur, India.

Prof. Jack Mustard and his graduate student, Kevin Cannon, at Brown University reported in Geology magazine that they had found impact glass in several craters on Mars. This discovery is particularly relevant to the Martian crater named after the late Princeton geoscience professor, Robert B. Hargraves *59. Mustard and his colleagues are...
