Responsible Conduct of Research in Geosciences (Half-Term)
GEO 503 / AOS 503
Course educates Geosciences and AOS students in the responsible conduct of research using case studies appropriate to these disciplines. This discussion-based course focuses on issues related to the use of scientific data, publication practices and responsible authorship, peer review, research misconduct, conflicts of interest, the role of mentors & mentees, issues encountered in collaborative research and the role of scientists in society. Successful completion is based on attendance, reading, and active participation in class discussions. Course satisfies University requirement for RCR training.

Instabilities in Fluids: Linear and Non-Linear Analysis of Waves and Patterns in the Environment
MAE 563 / AOS 563
This course describes natural patterns arising from instabilities in nature, and discusses their importance in the environment. We analyze phenomena at various scales, as diverse as wave breaking at the ocean surface, internal mixing in the atmosphere and the ocean, volcanic plumes, convection cells in the atmosphere, the break-up of fluid ligaments or bubble bursting at an interface. The course details mathematical tools (linear and non-linear stability analysis, symmetry arguments, solutions to non-linear equations such as shocks and solitons), as well as present laboratory and numerical demonstration of the instabilities.
Atmospheric and Oceanic Wave Dynamics
Observational evidence of atmospheric and oceanic waves; laboratory simulation. Surface and internal gravity waves; dispersion characteristics; kinetic energy spectrum; critical layer; forced resonance; instabilities. Planetary waves: scale analysis; physical description of planetary wave propagation; reflections; normal modes in a closed basin. Large-scale barclinic and barotropic instabilities. Eady and Charney models for barclinic instability, and energy transfer.
Sonya Allayne Legg
Response of the ocean to transient and steady winds and buoyancy forcing. A hierarchy of models from simple analytical to realistic numerical models is used to study the role of the waves, convection, instabilities, and other physical processes in the circulation of the oceans.
AOS 578 / GEO 578
The chemical composition of the oceans and the nature of the physical and chemical processes governing this composition in the past and present. The cycles of major and minor oceanic constituents, including interactions with the biosphere and at the ocean-atmosphere and ocean-sediment interfaces.
The Physics of Glaciers
GEO 576 / AOS 579
Glaciers and ice sheets are important elements of Earths global climate system. This course introduces graduate students to the history of ice on Earth, contemporary glaciology, and the interactions between climate, glaciers, landforms, and sea level. Drawing from basic physical concepts, lab experiments, numerical modeling, and geological observations, we tackle important physical processes in glaciology, and equip students with data analysis and modeling skills. Students gain an appreciation for the importance of ice sheets for the global climate system, and the large gaps that remain in our understanding.
