Graduate

Comprehensive treatment of modern conceptual and methodological approaches to hydrological science. Combines qualitative understanding of hydrological processes with quantitative representation, approaches to measurement, and treatment of uncertainty. Major components of the hydrological cycle and their linkages within the coupled Earth system. Prerequisite: Earth System Science 60A or 51 or consent of instructor.

An examination of the interactions between plants and their environment. Emphasis on the underlying physiological mechanisms of plant function, adaptations and responses to stress, and the basis of the distribution of plants and plant assemblages across the landscape. Prerequisites: Earth System Science 51 or 60A and 60C or Biological Sciences E106.

Weekly seminars and discussions on topics of general and current interest in Earth System Science. Satisfactory/Unsatisfactory only. Prerequisite: graduate standing.

Each quarter is devoted to current topics relating to Ecosystems. May be repeated for credit as topics vary. Prerequisite: Earth System Science 200 or equivalent, or consent of instructor.

Each quarter is devoted to in-depth analysis of a subarea in biogeochemistry which is undergoing rapid development. Prerequisite: Earth System Science 200 or equivalent, or consent of instructor.

Each quarter is devoted to current topics in the field of Atmospheric Chemistry. Prerequisite: Earth System Science 200 or equivalent, or consent of instructor

Each quarter is devoted to indepth analysis of an important and rapidly developing area in the field of climate dynamics. Prerequisite: Earth System Science 200 or equivalent, or consent of instructor.

Lecture, two hours; field work, one hour. An investigation of the mechanisms that underlie responses of organisms to human-caused environmental changes. Activities include field trips, literature discussions, and lectures. Focuses on issues of interest in Southern California, including nitrogen deposition, invasions, and habitat fragmentation.

Computer-based course. Fundamental statistical techniques needed to analyze Earth system data and models. Basic numerical techniques to solve Earth system models. Focuses on linear and non-linear ordinary differential equations, as well as simple partial differential equations.

Supervised original research in areas of Earth System Science. Prerequisite: consent of instructor. May be repeated for credit.
