TEACHING

Introduction to Oceanography (EVSC 2050)
Analyzes the principles that govern the world's oceans and their integration into an understanding of the major marine environments. Topics include marine pollution, global climate, and marine policy.

Topics in Oceanography(EVGE 4050)
Introduces oceanography together with a survey of marine resources and the scientific bases for their management.

Advanced Oceanography (EVSC 5050)
The principles of oceanography with views on real world applications, especially to the teaching of this class at the high school as well.

Geochemistry (EVGE 5850)
Studies the principles that govern the distribution and abundance of the elements in the earth's lithosphere, hydrosphere, biosphere, and atmosphere.

Isotope Geochemistry (EVSC 5860)
Investigates natural phenomena by means of stable and unstable isotopes and changes in their abundance, including isotope fractionation. Includes age dating, paleotemperature determination, and isotope tracers in natural systems.
