Microorganisms inhabit almost every conceivable environment on the planet's surface, and extent the biosphere to depths of several kilometers into the crust. 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 an interdisciplinary and "global" view of microbe-environment interactions.

This course will cover some fundamental topics in Climate Sciences, while also teaching how to program & work with big data in Python. We will analyze big climate data (output from the newest generation climate models CMIP6 and NASA satellite datasets) remotely on a National Center for Atmospheric Research (NCAR) supercomputer.

Advanced Environmental Fluid Dynamics (EFD) is an applied branch of fluid mechanics devoted to studying fluid systems in nature, including atmospheric boundary layers and aquatic environments, such as lakes, rivers, and coastal seas. In particular, EFD aims to characterize the mechanisms governing the transport of heat, dissolved, and suspended matter in fluid environments, which together play a critical role in the functioning of ecosystems.
This course will introduce the underlying physics governing motion in natural fluids, with
emphasis on water bodies. We will discuss the transport equations that model fluid flows
affected by vertical and horizontal density gradients, the effect of Earth rotation in fluid
trajectories, and the main natural drivers responsible for energizing fluid flows, such as wind and heat fluxes. The course will revisit analytical results characterizing specific type flows in nature, and we will discuss open topics that are under development.

This course provides a comprehensive introduction to theory and applications of chemistry in the earth and environmental sciences. Theory covered will include atomic structure, chemical bonding, cosmic abundances, nucleosynthesis,radioactive decay, dating of geological materials, stable isotopes, acid-base equilibria, salts and solutions, and oxidation-reduction reactions. Applications will emphasize oceanography, atmospheric sciences and environmental chemistry, as well as other topics depending on the interests of the class. Although we will review the basics, this course is intended to supplement, rather than to replace, courses offered in the Department of Chemistry. It is appropriate for advanced undergraduate as well as graduate students in Geology, Environmental Science, Chemistry and other sciences, who wish to have a better understanding of these important chemical processes.

Patterns on the Earth's surface arise due to the transport of sediment by water and 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.

All forms of frozen water at Earth's surface define the cryosphere. These icy environmnets are an integral part of the global climate system, with important linkages and feedbacks resulting from their influences on surface energy and moisture fluxes, clouds, precipitation, hydrology, and circulation in the atmosphere and oceans. This course will survey the various components of the cryosphere and their interactions with climate, with a strong emphasis on the dynamics of glaciers and ice sheets. Broad topics to be covered are 1)the rudimentary mechanics of glacier and ice sheet flow, 2)fast-flowing ice streams and factors limiting their motion, 3)ice-quakes and their origins, 4)the nature of climate data recorded in natural ice bodies, 5)the influence of climate on the stability of ice sheets and glaciers, and 6)glacier-like flow on other planetary bodies. This will be a lecture-based course with written assignmnets and problems sets.
