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.

Dangerous storms are one reason the Southern Ocean is so under-researched, although it absorbs almost half of the world’s man-made carbon emissions. Last week, more than 50 researchers (Ethan Campbell '16 and Preston Kemeny '15) returned from a scientific voyage of Antarctica, the first leg of a two-year experiment – the 3rd Southern Ocean...

A concern among scientists is that higher Arctic temperatures brought about by climate change could result in the release of massive amounts of carbon locked in the region’s frozen soil in the form of carbon dioxide and methane. New research led by researchers at the Department of Geosciences and published in The ISME Journal suggests that, thanks...
