The course will provide a basic understanding of how the ocean functions as a suite of interconnected ecosystems, both naturally and under the influence of human activities. Emphasis is on the interactions between the physical and chemical environment and the dominant organisms of each ecosystem. The types of ecosystems discussed include coral reefs, deep-sea hydrothermal vents, coastal upwelling systems, blue-water oceans, estuaries, and near-shore dead zones. Lectures, multimedia presentations, group activities, and tide-pooling day trip.

Southeast Alaska is often described as America's "last frontier," embodying a physical reality of the "pristine" that was once revered by the early romantics and founders of the modern conservation movement throughout Western North America. Although endowed with more designated Wilderness land than any other state, Alaska remains a working landscape: a mixed cash-subsistence economy where communities rely upon the harvest and export of natural resources. Here, ecosystem services remain tangible, and people living in communities that are unconnected by roads confront questions of sustainability on a daily basis. This field-based course introduces students to the global questions of land use change and sustainable resource management in the American West through the place-based exploration of Southeast Alaska. Focused on four key social-ecological challenges -- fisheries, forestry, tourism, and energy -- the coupled human-natural systems of Southeast Alaska provide a unique lens for students to interpret broader resource management and conservation issues. The curriculum balances field explorations and classroom lectures with community exploration in which students will engage with fishermen, hatchery workers, forest managers, loggers, mill owners, tour operators, tourists, city officials, citizens, and Native residents. Students will catch their own salmon, walk through old-growth and logged forests, kayak next to glacial moraines, and witness the impacts of human activities, both local and global, on the social-ecological systems around them. In the context of rapidly changing ecosystems, students will confront the historical, ecological, and economic complexities of environmental stewardship in this region. By embedding their experiences within frameworks of land change science, land-ocean interactions, ecosystem ecology, and natural resource management and economics, students will leave this course ready to apply what they have learned to the global challenges of sustainability and conservation that pervade systems far beyond Alaska. This course is co-sponsored by the School of Earth Sciences and takes place in Sitka, Alaska. Students arrange for their arrival at the seminar's point of origin; all subsequent travel is made possible by Sophomore College and the School of Earth Sciences.

The ecologically and geologically diverse Rocky Mountain area is being strongly impacted by changing land use patterns, global and regional environmental change, and societal demands for energy and natural resources. This field program emphasizes coupled environmental and geological problems in the Rocky Mountains, covering a broad range of topics including the geologic origin of the American West from three billion years ago to the present; paleoclimatology and the glacial history of this mountainous region; the long- and short-term carbon cycle and global climate change; and environmental issues in the American West related to changing land-use patterns and increased demand for its abundant natural resources. In addition to the science aspects of this course we will also investigate the unique western culture of the area particularly in regards to modern ranching and outfitting in the American West. These broad topics are integrated into a coherent field-study as we examine earth/ environmental science-related questions in three different settings: 1) the three-billion-year-old rocks and the modern glaciers of the Wind River Mountains of Wyoming; 2) the sediments in the adjacent Wind River basin that host abundant gas and oil reserves and also contain the long-term climate history of this region; and 3) the volcanic center of Yellowstone National Park and the mountainous region of Teton National Park. Students will complete six assignments based upon field exercises, working in small groups to analyze data and prepare reports and maps. Lectures will be held in the field prior to and after fieldwork. The students will read two required books prior to this course that will be discussed on the trip.nnNote: This course involves one week of backpacking in the Wind Rivers and hiking while staying in cabins near Jackson Hole, Wyoming. Students must arrive in Salt Lake City on Monday, September 4. (Hotel lodging will be provided for the night of September 4, and thereafter students will travel as a Sophomore College group.) We will return to campus on Friday, September 22.

This course examines the motivations and experiences of polar explorers under the harshest conditions on Earth, as well as the chronicles of their explorations and hardships, dating to the 1500s for the Arctic and the 1700s for the Antarctic. Materials include The Worst Journey in the World by Aspley Cherry-Garrard who in 1911 participated in a midwinter Antarctic sledging trip to recover emperor penguin eggs. Optional field trip into the high Sierra in March.

Further discussion of the complex climate challenges posed by the substantial benefits of energy consumption, including the critical tension between the enormous global demand for increased human well-being and the negative climate consequences of large-scale emissions of carbon dioxide. Discussions of topics of student interest, including peer-reviewed scientific papers, current research results, and portrayal of scientific findings by the mass media and social networks. Focus is on student engagement in on-campus and off-campus activities. Prerequisite: EESS 41N or EARTHSYS 41N or consent of instructor.

Preference to freshmen. Field trips to sites in the Elkhorn Slough, a small agriculturally impacted estuary that opens into Monterey Bay, a model ecosystem for understanding the complexity of estuaries, and one of California's last remaining coastal wetlands. Readings include Jane Caffrey's "Changes in a California Estuary: A Profile of Elkhorn Slough". Basics of biogeochemistry, microbiology, oceanography, ecology, pollution, and environmental management.

This course will be focused around San Francisco Bay, the largest estuary on the Pacific coasts of both North and South America as a model ecosystem for understanding the critical importance and complexity of estuaries. Despite its uniquely urban and industrial character, the Bay is of immense ecological value and encompasses over 90% of California's remaining coastal wetlands. Students will be exposed to the basics of estuarine biogeochemistry, microbiology, ecology, hydrodynamics, pollution, and ecosystem management/restoration issues through lectures, interactive discussions, and field trips. Knowledge of introductory biology and chemistry is recommended.

Preference to sophomores. Recent changes in the California current, using Monterey Bay as an example. Current literature introduces principles of oceanography. Visits from researchers from MBARI, Hopkins, and UCSC. Optional field trip to MBARI and Monterey Bay.
