Courses
GEO 103. Earth Surface Environments and Environmental Change/Lab.
The Earth's surface environments are in a constant state of change resulting from the interaction of its atmosphere, hydrosphere, biosphere, and lithosphere. Changes on the surface occur on various time scales from brief, severe storms to glaciations lasting thousands of years and changes in continents and ocean basin environments occurring over millions of years due to tectonic processes. Studies of surficial processes and materials illustrate the dynamic nature of the Earth and provide a key to understanding past and future environmental change. The lectures are complemented with field and laboratory study. Field experiences include day trips to local geologic settings and to the Maine coast. Enrollment limited to 30. Normally offered every year. [L] [Q] [S] M. Retelle, A. Doughty.
Concentrations
GEO 104. Plate Tectonics and Tectonic Hazards/Lab.
Volcanoes, earthquakes, and tsunamis are examples of tectonic hazards that directly affect human populations. Yet the processes responsible for such natural hazards are an integral part of the global tectonic cycle that over millions of years results in the formation of ocean basins, mountain ranges, and the global-scale motion of continents. Study of active and ancient tectonic activity is key to forecasting future volcanic eruptions and earthquakes as well as global environment change. The laboratory component emphasizes understanding global tectonic processes and reconstructing the tectonic history of southwestern Maine through field studies. Enrollment limited to 26. Normally offered every year. [L] [Q] [S] G. Robert.
Concentrations
GEO 107. Katahdin to Acadia: Field Geology in Maine/Lab.
The rocky coast and glaciated bedrock mountains of Maine have a rich 500-million-year geologic history. This hands-on, outdoor-oriented course on Maine's geologic history includes weekly half-day field trips to local geologic settings, two required day-long field trips to the Presidential Range and a Maine island, and one or two required weekend trips to Acadia National Park or Baxter State Park. Reading and making maps, recording field observations, writing papers, giving talks, and making posters about the variety of geologic environments are the major features of the course. The required trips involve strenuous hiking and sea kayaking. Appropriate outdoor clothing and footwear is needed. Not open to students who have received credit for FYS 327. Enrollment limited to 29.

Currently, humans are perturbing these components at unprecedented rates, resulting in environmental change on regional and global scales. In this course, students examine the Earth system on multiple timescales and investigate current topics in global change, including the impact of greenhouse gases on global climate, sea level, El Niño, global dimming, and ocean acidification. Two required day-long field trips to the Maine coast take place on weekends. Not open to students who have received credit for GEO 109. Enrollment limited to 44. [Q] [S] B. Johnson.
