Overview:

This course integrates atmospheric, oceanographic, geological and biological concepts in an historical perspective to introduce the student to the major processes that have shaped Earth's environment. The course will examine climatic processes on geological time scales, the evolution of organisms, the cycling of elements, and the feedbacks between these processes. Prerequisites: Introductory courses in Chemistry, Biology, and Physics (or by consultation with the Instructor).

Goals:

The primary goal of this course is to introduce upper level undergraduate and graduate science majors to the complexity of Earth as a physical/biological system. The course is aimed at challenging the student to think about connections between various science disciplines (e.g. Molecular phylogeny and climatic variability). The course will emphasize learning rigorous, fundamental concepts in science (e.g. Stefan-Boltzmann equation, the Poisson probability function, the Nernst equation) as applied to understanding radiative transfer, rates of genetic change, etc.

Philosophy:

The course will be taught as a lecture series, building from an historical perspective, and noting the contributions of specific scientists to our knowledge of Earth System Science. The course will use one primary text with supplemental reading from other texts and review articles in the primary literature. Course grades will be based on a mid-term exam (short answer and essay questions - 30% of total), a comprehensive final - (short answer and essay 30% of total), and a term paper that reviews a specific topic in Earth System Science (40% of total). The term paper for the 400 level course will be 15 page review of literature in a course topic. At the 500 level, the term paper will be modeled as an NSF style Research Proposal, and focus on an examination of competing hypotheses in Earth System Science with a detailed research plan that would reconcile the hypotheses. The course will be modeled on similar courses taught at Berkeley in Integrative Biology.

SAMPLE FINAL EXAM QUESTIONS

Sample types of questions:

There will be some short answer questions of the following general type (you will not have options to select questions):

1. What appears to be the "pacemaker" for glacial/interglacial cycles for the past 2.5 million years of Earth's history?

2. What is one proxy for wind speed that can be inferred from ice core records? What is the rationale for using it as a proxy?

3. How does metabolic rate scale with body size in metazoans?

4. What is one difference between human induced changes to the Earth System compared with natural changes?

5. How has the evolution of language helped humans to escape the Red Queen constraint?

There will be short essays of the following general form:

E1. There are two carbon cycles on Earth – a “slow cycle” and a “fast cycle”. Describe the basic features of both cycles (you can use a diagram if you like) and explain how human activities have disrupted the cycle(s).

E2. Explain how mass extinctions differ from “normal” extinction processes, and why mass extinctions are always followed by major radiations. In addressing these issues choose specific examples, whenever possible.
