350  Paleoclimatology
A. Leventer
Earth's climate has fluctuated widely in the past, between droughts, warm periods, and ice ages. In fact, climate change is a certainty. The planet is currently faced with potential abrupt climate change resulting from human-induced environmental modification. Paleoclimatology, the study of past climates and environments of the Earth, provides a long-term perspective on the nature of global climate variability that is critical for evaluating the sensitivity of the Earth system to past, present, and future changes. This course provides students with an overview of paleoclimatology by examining the use of proxy records such as marine and lake sediment sequences, ice cores, tree rings, corals, and historical data to reconstruct past climatic conditions. Dating methods are introduced, and seminal publications in paleoclimatology are reviewed in tandem with current research papers addressing outstanding questions in paleoclimatology. Throughout, students critically analyze their current understanding of past climates and environments, and identify promising directions for future research. Topics include abrupt climate change, human evolution and climate, biosphere-climate interactions, and paleoclimate modeling. Prerequisites: GEOL 215 or 302 or permission of instructor.

Methods to be investigated include geochronology, radiogenic isotopes in magmatic systems, stable isotopes as applied to understanding fluids in low- and high-temperature environments, stable isotopes and the paleoclimate record, and the radiogenic and stable isotope cosmochemistry of meteorites and lunar samples. Current research in these fields (and readings in the primary scientific literature) will be a focus of this course. Prerequisites: four geology courses, including GEOL 202 (may be concurrent) or permission of instructor.

415  Seminar on Reefs
C. Soja
Reefs are "organic fantasias," some of one of the most visually stunning and biologically diverse ecosystems on our planet. This course focuses on their biology and geology, evolutionary history, and conservation. Complex ecologic partnerships that have contributed to the evolutionary success of reefs in the past two billion years are examined to predict their survival in a modern environmental context. Students research why reefs are sensitive environmental indicators, how ancient reefs yield clues about past climate change, and the ways in which modern reefs monitor the health of world oceans. Seminar discussions are based on multidisciplinary research; on oral and poster presentations, debates, review panels, and symposia; and on interactions with invited speakers. These are enhanced by an investigation of modern and Pleistocene (fossil) reefs during an optional field trip to the tropics over spring break (or in January). Prerequisites: GEOL 215, GEOL 302 (may be concurrent), or permission of instructor.

415L  Tropical Field Course on Modern and Pleistocene Reefs
C. Soja
Intensive investigation of fossil and modern reefs is the focus of this 0.25-credit, field-based "outdoor laboratory" course. Student participants complete a project based on collection of data in the field to learn first-hand about coral reefs, one of the most important and most threatened ecosystems on Earth. During a nine-day trip to the tropics over spring break (or January), students engage in practical exercises to study reef communities past and present. Research projects involve snorkeling to make observations of modern reefs and their inhabitants, including aquatic surveys to assess biodiversity. Projects also include comparison of modern reefs with fossil (Pleistocene) reefs exposed on land. Final reports rely on these and other data to assess the changes reef species have experienced in abundance, diversity, and health through time; and to consider debates about the past, present, and future status of coral reefs. Students complete a short final paper and present research results after they return to campus. Prerequisites: GEOL 215, GEOL 302 (may be taken concurrently), or permission of instructor. This course is graded as satisfactory/unsatisfactory (S/U).

Students learn and apply essential concepts in general physics, astronomy, and meteorology.

SEA 204  Practical Oceanography I (basic)
Staff
This course, completed during the first three weeks of the sea component, allows students to acquire the skills and knowledge of the practicing oceanographer by observing and applying the concepts and sampling techniques introduced on shore. As students become familiar with the operation of a research vessel under sail, they learn to carry out routine lab procedures and safely deploy and recover oceanographic equipment. The extraction of physical data and processing of chemical and biological samples is carried out by the lab watch once the equipment is recovered and secured.

SEA 205  Practical Oceanography II (advanced)
Staff
During the second three weeks at sea, scientific sampling continues and students are given increasing responsibility for routine lab work, the sampling program, and operation of the vessel. Science watch officers begin to take a back seat on lab operation, allowing students to make decisions and keep things running, while they focus on helping with data processing and paper writing. By the end of the cruise, students will be overseeing the lab watch, directing their peers, and planning and carrying out station work with minimal staff supervision. The major focus of this course is the completion of student research projects.

SEA 206  Practical Oceanographic Research (summer only)
Staff
This course provides practical experience in conducting oceanographic research on board a sailing research vessel. During four weeks at sea, the scientific staff guides students from an introductory learning phase to increasing responsibility in station planning, equipment deployment, and data interpretation.
