270.104 FLUID EARTH A broad survey of the oceans and atmosphere, and their role in the environment and climate. Subjects include ocean circulation, weather systems, hurricanes and tornadoes, El Nino, climate change, ozone depletion, and marine ecosystems. Open to science and non-science majors.

270.396 GLOBAL BIOCHEMICAL CYCLES AND CLIMATE CHANGE This course offers an integrated examination of chemical processes operating in the atmosphere, the hydrosphere, the lithosphere and interior of the Earth, and their role in the evolution of the Earth System. Emphasis will be on global chemical cycles and the coupling between the different components that make up the Earth System (e.g. atmosphere -ocean interactions; hydrosphere-lithosphere interactions, etc.). The Earth's present and past climate system and the origin and evolution of the chemistry of the atmosphere, the oceans, and the solid Earth will be explored.

270.646 FLUID DYNAMICS OF THE EARTH AND PLANETS A first course in the mechanics of Earth and Planets fluids systems. The focus is on fundamental fluid processes and their applications to phenomena occurring in the atmospheres, oceans, and interior of Earth and other planets.

270.614 ATMOSPHERIC AND OCEANIC VORTICES The fundamental dynamics of vortices in rapidly rotating, stratified fluids is discussed and used to examine the structure and dynamics of vortices occurring in the Earth's atmosphere (e.g., stratospheric polar night jet and blocking anticyclones) and oceans (e.g., Gulf Stream rings) and in the atmospheres of the outer planets (e.g., `Great Spots' on Jupiter, Saturn, and Neptune).
