The culmination of the Earth Science major. Students, while working with an advisor in their concentration, conduct research and write a thesis. Prerequisite: GEOL 400-level and declaration of the EASC major. The Earth Science major, as of the fall of 2008, requires 1 semester of GEOL 399 and two semesters of GEOL 498.

Microorganisms inhabit almost every conceivable environment on the planet's surface, and extent the biosphere to depths of several kilometers into th ecrust. Significantly, the chemical reactivity and metabolic diversity displayed by microbial communities make them integral components of global elemental cycles, from mineral dissolution and precipitation reactions, to aqueous reduction-oxidation processes. In that regard, microorganisms have helped shape our planet overthe past 4 billion years and made it habitable for higher forms of life. In this course we will evaluate the geological consequences of microbial activities, by taking am interdisciplinary and "global" view of microbe-environment interactions.

This course deals with the study of the two main parts of Earth's climate system, the atmosphere and the ocean. It explores, qualitatively and quantitatively,the physical laws, geological and geographical processes, and mass and energy budgets that govern these two parts and their combined influence on Earth's past and present climate. Main topics covered include, but not limited to, properties of air and water; physical balances; equilibrium states; transport of heat and mass; clouds; precipitation; storms; regional and global climate; ozone layer; seasons and climate; weather forecasting; atmospheric optics; ocean currents; ocean bathymetry, salinity, and atmospheric forcing; history of Earth's changing climate in the geologic record, global warming, and how climate impacts humans and how do humans impact climate.

This seminar is designed to help Juniors prepare for the Senior Thesis research. Topic selection, advisor identification, funding options, and basic research methods will be discussed.

Occurrences and origins of igneous and metamorphic rocks; phase equilibria in heterogeneous systems. Laboratory study of rocks and thin sections as a tool in interpretation of petrogenesis. Two field trips.

Patterns on the Earth's surface arise due to the transport of sediment by waterand wind, with energy that is supplied by climate and tectonic deformation of the solid Earth. This course presents a treatment of the processes of erosion and deposition that shape landscapes. Emphasis will be placed on using simple physical principles as a tool for (a) understanding landscape patterns including drainage networks, river channels and deltas, desert dunes, and submarine channels, (b) reconstructing past environmental conditions using the sedimentary record, and (c) the management of rivers and landscapes under present and future climate scenarios. The course will conclude with a critical assessment of landscape evolution on other planets, including Mars.

Introduction to deformation as a fundamental geologic process. Stress and strain; rock mechanics. Definition, measurement, geometrical and statistical analysis, and interpretation of structural features. Structural problems in the field. Maps, cross-sections, and three-dimensional visualization; regional structural geology. Three field trips required. Prerequisite: PHYS 150 strongly recommended.
