• GRS ES 699: Teaching College Earth Sciences I
  The goals, contents, and methods of instruction in earth sciences. General teaching-learning issues. Required of all teaching fellows.
• GRS ES 701: Quantitative Methods for Earth Sciences 1: Mechanics of Earth Materials
  Characterization of the response of complex natural systems to forcing, using the methods of continuum mechanics. Applications include magma migration, the propagation of seismic waves, glacial flow, oceanic thermohaline circulation, and thermochemical convection in the Earth's mantle.
• GRS ES 702: Quantitative Methods for Earth Sciences II: Analysis and Modeling of Geologic Processes
  Quantitative techniques for deriving models of geologic processes from physical measurements. Applications include marine sediment composition, soil response to solar heating, seismic-wave propagation in the mantle, estuarine water quality, glacial and interglacial cycles, and olivine deformation.
• GRS ES 719: Colloquium in Terrestrial Biogeoscience
  Introduction to the field of Terrestrial Biogeoscience through weekly research presentations and discussions with GRS faculty and distinguished guests. Students also meet weekly with lead faculty member to discuss primary literature related to each presentation. Also offered as GRS BI 719 and GRS GE 719.
• GRS ES 720: Practicum in Terrestrial Biogeoscience
  Analysis and synthesis of the primary literature via in-depth case studies in terrestrial biogeoscience. Students meet weekly with faculty to read papers from the primary literature, synthesize results, and prepare a peer-review quality paper on the case study. Also offered as GRS BI 720 and GRS GE 720.
• GRS ES 771: Isotope Earth Science
  Stable and radiogenic isotope geochemistry; isotope geology of hydrogen, carbon, oxygen, nitrogen, chlorine, and sulphur; applications of isotope systematics to geochemical problems in hydrology, ocean biogeochemistry, and crustal genesis. (Offered alternate years.)
• GRS ES 772: Trace Element Geochemistry
