Professor John A. Higgins
Title: Associate Professor of Geosciences
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.

Upcoming Semester - SPRING 2021
GEO 360 / ENV 356 - Geochemistry of the Human Environment
Humans have profoundly altered the chemistry of Earth's air, water, and soil. This course explores these changes with an emphasis on the analytical techniques used to measure the human impact. Topics include the accumulation of greenhouse gases (CO2 and CH4) in Earth's atmosphere and the contamination of drinking water at the tap and in the ground. Students will get hands on training in mass spectrometry and spectroscopy to determine the chemical composition of air, water, and soil and will participate in an outreach project aimed at providing chemical analyses of urban tap waters to residents of Trenton, NJ.
