An integrated, interdisciplinary overview of the chemistry, physics, geology, and biology of the world's oceans. Topics include chemical and physical properties of sea water, ocean circulation, evolution of ocean basins, coastal geomorphology, the distribution and abundance of organisms in the major marine communities, the status of the world's most important fisheries, and the role of the ocean in the global carbon cycle. The course may include weekend field trips. Not open to students who have received credit for Biology/Geology 113. Not open to students who have received credit for BI/GE 113. Enrollment limited to 40. [S] [L] [Q] W. Ambrose.

What happens when a ten-kilometer rock, traveling at forty kilometers per second, hits the Earth As the dinosaurs discovered sixty-five million years ago, it is not a pretty picture. Scientists now believe that such catastrophically violent collisions, apparently common in the past, are inevitable in the future as well. But impacts alone may not explain the mass extinction events that have shaped the history of life on Earth; global-scale volcanism and climate change are examples of more familiar processes. This course examines the role of impacts in the Earth's history and the heated debate regarding the causes of mass extinctions. Enrollment limited to 64. [S] [Q] E. Wollman.

Geographical information systems (GIS) are computer-based systems for geographical data presentation and analysis. They allow rapid development of high-quality maps, and enable sophisticated examination of spatial patterns and interrelationships. In this course students learn the principles of GIS through extensive computer use of ArcGIS (ESRI). Geological and environmental projects introduce students to cartography, common sources of geographic data, methods for collecting novel spatial data, and data quality. Finally, students learn to extend the capabilities of GIS software to tackle more advanced spatial analysis tasks by completing an independent project. Lectures supplement the laboratory component of the course. Prerequisite: one 200-level course in environmental studies or one 100-level course in geology. Not open to students who have received credit for Environmental Studies 217. Enrollment limited to 20. [S] [L] [Q] J. Eusden, C. Parrish.

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, to 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 the Saco River, the Maine coast, or the White Mountains. Enrollment limited to 52. [S] [L] [Q] Normally offered every year. M. Retelle.

Volcanoes, earthquakes, and tsunamis are examples of tectonic hazards that directly affect human populations. Yet the processes responsible for such natural hazards are an intergral 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 52. [S] [L] [Q] Normally offered every year. J. Creasy.

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 required weekend trip to Acadia National Park or Baxter State Park, on weekends to be determined. 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 First-Year Seminars 327. Enrollment limited to 20 per section. [S] [L] [Q] Normally offered every year. J. Eusden.

The Earth's system is comprised of the dynamic interactions between its various components: the biosphere, lithosphere, hydrosphere, and the atmosphere. 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 Ni o, 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 Geology 109. Enrollment limited to 44. [S] [Q] B. Johnson.

The Earth's system is comprised of the dynamic interactions between its various components: the biosphere, lithosphere, hydrosphere, and the atmosphere. Mounting evidence indicates that 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 Ni o, global dimming, and ocean acidification. Laboratories include field trips to sitesthat illustrate environmental change on local and regional scales. Not open to students who have received credit for Geology 108. Enrollment limited to 22. [S] [L] [Q] Normally offered every year. B. Johnson.

The study of modern sedimentary processes and environments provides geologists with a basis for comparison with ancient deposits preserved in the rock record. The analysis of modern sedimentary environments and reconstruction of ancient environments permit stratigraphic reconstructions at regional and global scales. Laboratory work includes field studies of processes and interpretation of modern and ancient depositional systems. Prerequisite(s): any two introductory geology courses or one introductory geology course and one of the following: Chemistry 107A, Chemistry/Environmental Studies 107B, Mathematics 105, or Physics 107. [S] [L] [Q] [W2] Normally offered every year. M. Retelle.
