Earth Science

Requirements for Concentration: 11 units including Earth Science 151, 161, and 201, 2 units of graded work at the 300-level, and not more than 1 additional unit at the 100-level. With consent of the student’s adviser, students may substitute one 200- or 300-level course in biology, chemistry, mathematics, or physics for 200-level work in earth science. Students may not count toward the major more than 2 courses originating in geography and cross-listed with earth science (even numbered courses at the 200 and 300-level). No more than 1 unit of field work may count toward the major. After declaration of the major, no required courses may be elected NRO.

Senior-Year Requirement: One graded 300-level course.

Independent Research: The earth science program encourages students to engage in ungraded independent research with faculty mentors and offers ungraded courses Earth Science 198, 298, and 399. The department also offers Earth Science 300-301, an ungraded research experience for senior majors. Students who complete 300-301 are eligible for departmental honors upon graduation. Students should consult the chair or individual faculty members for guidance in initiating independent research.

Field Work: Many graduate programs in earth science expect that earth science majors will have attended a geology summer field camp for which students can receive field work credit in the department. Students should consult with the chair of earth science about summer field camps. Additional fieldwork options include working with local environmental consulting companies and non-profit agencies. Students should consult an earth science faculty adviser for details.

Teaching Certification: Students who wish to obtain secondary school teaching certification in earth science should consult both the earth science and education departments for appropriate course requirements.

Early Advising: Knowledge of earth science is useful in a variety of careers. Therefore, we urge potential majors to consult with a faculty member in earth science as soon as possible to determine a course of study that reflects the interests and aspirations of the student. The earth science program also offers courses at the 100-level designed for students who may not intend to pursue earth science at more advanced levels. These courses are appropriate for students curious about the earth and its life, especially those with concerns about environmental degradation and its impact on people living in both urban and rural settings.

Postgraduate Work: Students interested in graduate study in earth or environmental science should be aware that graduate and professional schools usually require courses beyond the earth science concentration requirements. In general, students should have a year of biology, chemistry, physics and/or calculus, depending on the field of interest. Appropriate courses include Biology 105 and 106; Chemistry 108/109 or 125; Physics 113 and 114; and Mathematics 101 and 102 or 121/122. We urge students to begin coursework in other sciences as soon as possible, since this assists them in successful completion of the earth science major.

Advisers: Mr. McAdoo, Ms. Menking, Ms. Schneiderman, Mr. Walker.

Correlate Sequence in Earth Science: The Department of Earth Science and Geography offers a correlate sequence in earth science. The correlate sequence complements the curricula of students majoring in other departmental, interdepartmental, and multidisciplinary programs. Students interested in a correlate sequence in earth science should consult with one of the earth science faculty members. The requirements for the correlate sequence in earth science are five courses in the department including Earth Science 151, 161, and at least one 300-level course. Students should note the prerequisites required for enrollment in some of the courses within the correlate sequence.

(Same as Geography 181a.) From heat waves to cold snaps, tropical cyclones and the doldrums, this class explores the geophysical basis for our weather. We discuss atmospheric structure, the role of global circulation and heat transport, and the effects humans are having on this complex system. How do we know if it is going to rain next week? How does coal burning in China affect rainfall in Seattle? Are hurricanes getting more intense? As humans and the atmosphere are intimately linked, we also discuss the ways that we are changing the atmosphere and how the atmosphere is changing us. Mr. McAdoo.

Two-75 minute periods.

185b. Geoscience and the Development of Modern Israel-Palestine (1)

In this introductory level course students gain a rigorous understanding of earth system science and explore the underlying influence of geologic processes on human events. Students develop a deep understanding that human history has been dramatically influenced by the actions and accidents of geologic processes. We consider topics in earth system science directly relevant to particular historical, cultural, political, or economic issues in Israel. These include: past and present fluvial processes of the Jordan River System; climate change in Israel, North Africa, and the Middle East; mineral resources in Israel; the structure and evolution of the Dead Sea Transform Fault Zone. Once the geologic framework for a given topic has been firmly established, students work out the connections between geology and the relevant human issues. The course centers on the following overarching principles: --that understanding geology is instrumental in recovering our human past, understanding the present, and predicting the future and that a significant number of human events cannot be completely understood without understanding the underlying role of earth system science, geologic processes, and the environment. --that science plays a unique role in providing real data for decision-making but that scientific data rarely form the only basis for making decisions in public and private arenas. The course is especially intended for first-year students and sophomores who have had no previous earth science courses. Ms. Schneiderman.

Two 75-minute periods plus one 4-hour lab.

198a or b. Special Projects in Earth Science (1/2 or 1)

(Same as Geography 220a.)

Not offered in 2011/12.

221a. Soils and Sustainable Agriculture (1)

(Same as Geography 221a.) Soils form an important interface between the lithosphere, hydrosphere, atmosphere, and biosphere. As such, they are critical to understanding agricultural ecosystems. This course studies soil formation, and the physical and chemical properties of soils especially as related to the sustainability of agricultural systems. Field trips and laboratory work focus on the description and interpretation of local agricultural soils. Mr. Walker.

Prerequisite: one introductory course in geology, biology, or chemistry.

Two 75-minute periods; one 2-hour discussion session.

(Same as Geography 231) Quantitative study of the geological processes and factors which influence the origin and development of Earth's many landforms. Topics include hillslope and channel processes, sediment transport, physical and chemical weathering and erosion, role of regional and local tectonics in the construction of marine terraces, mountain ranges and basins, and the role of climate in landscape modification. Ms. Menking.

Prerequisites: Earth Science 151 or 161.

Two 75-minute periods; one 4-hour laboratory/field session. An overnight weekend field trip may be required.

Not offered in 2011/12.

235b. Water (1)

(Same as Geography 235) Sixty to 70% of Dutchess County residents depend on groundwater supplies to meet their daily needs. Industrial pollution and road salt have contaminated many of these supplies, spawning legal actions and requiring costly remediation. Ensuring adequate and safe groundwater supplies for humans and ecosystems requires extensive knowledge of the hydrologic cycle and of how contaminants may be introduced into water resources. We explore how rainfall and snowmelt infiltrate into soils and bedrock to become part of the groundwater system, learn what factors govern subsurface flow, and discuss the concept of well-head protection, which seeks to protect groundwater recharge areas from contamination. Using Vassar's teaching well at the field station we perform a number of experiments to assess aquifer properties, water chemistry, and presence of microbial contaminants. Comfort with basic algebra and trigonometry is expected. Ms. Menking.

Two 75-minute periods and one 4-hour laboratory.

Prerequisite: ESCI 151.

Not offered in 2011/12.

251b. Global Geophysics and Tectonics (1)

What can physics and simple math tell us about the earth? By utilizing an array of techniques, geophysicists gain an understanding of the processes that shape our planet. Reflection and earthquake seismology give us insight into deep earth structure, plate tectonic mechanisms, mountain building, basin formation, and hazard mitigation. Variations in the earth's gravitational field yield information on density contrasts beneath the surface, from the scale of mountain ranges to buried artifacts. Heat flow variations are useful in determining regional subsurface thermal structure, fluid advection, and climate variation. Laboratories are designed to use the skills required in most geology related fields. They involve the use of Geographic Information System (GIS) software, and construction of simple computer models. Mr. McAdoo.

Prerequisites: Earth Science 151 or 161.

Two 75-minute periods; one 4-hour laboratory.

254b. Environmental Sciences in the Field:Louisiana's Coastal Processes and Environmental Quality (1)

(Same as Biology 254, Environmental Studies, and Geography 254b.) The environment consists of complex and often elegant interactions between various constituents so that an interdisciplinary approach is required to understand how human interactions may affect it. In this course, we study a variety of aspects of a specific environment by considering how biological, chemical, geological, and human factors interact. We observe these interactions first hand during a weeklong field trip. Some of the questions we may consider are: How does a coral polyp create an environment that not only suits its particular species, but also helps regulate the global climate? How has human development and associated water demands in the desert Southwest changed the landscape, fire ecology, and even estuary and fisheries' health as far away as the Gulf of California? How have a variety of species (humans included) managed to survive on an island with the harsh environment of the exposed mid-ocean ridge of Iceland? The course is offered every other year, and topics vary with expertise of the faculty teaching the course.

By special permission.

Topic for 2011/12: Louisiana's Coastal Processes and Environmental Quality. Coastal Louisiana's dynamic environment has endured repeated disturbances, such as hurricanes, oil and gas drilling, contamination from the Deepwater Horizon oil rig and other spills, and channelization of the Mississippi River. We examine the processes that shape this fragile coastline and its potential for recovery. The fieldtrip may include visits to Mississippi River levees and dams, coastal wetlands, barrier islands, and petrochemical refineries. Ms. Cunningham.

260a. Conservation of Natural Resources (1)

(Same as Geography 260a)

Not offered in 2011/12.

261a. Race and Class in the Hudson Valley: Geophysical Investigations (1)

This course integrates earth science, physics, geography, and social history to give students hands-on experience in original research, data analysis, and public presentation. The history of the Hudson Valley is one of immigrants, some voluntary and celebrated like the Dutch, others such as the African slaves, forced and forgotten. Working with local community groups, this project-based field course examines the history of the region's dispossessed populations by uncovering forgotten graveyards. During the course of the semester, the class uses both field geophysics and historical archives to map lost grave sites and to understand the historical and social context. Students gain experience using such tools as Geographic Information Systems (GIS), an electrical resistivity meter, a Cesium vapor magnetometer, and a ground penetrating radar. By the end of the semester, we synthesize the stories for a public presentation and final report. A new site is chosen for each class—field locations may include pre-Columbian or historical archaeological sites such as forgotten slave-era burial grounds and potters fields. Students from across the curriculum are welcome. Mr. McAdoo.

Prerequisites: Earth Science 151 or 161.

One 5-hour field session and one 75-minute classroom session.

Not offered in 2011/12.

271a. Structural Geology: Deformation of the Earth (1)

Prerequisites: Earth Science 151 or 161.

Two 75-minute periods; one 4-hour laboratory/field session. An overnight weekend field trip may be required.

285a. Volcanology (1)

Volcanoes are an important window into the workings of the earth's interior. They are also spectacular landscape features: serene in repose, and often violent in eruption. This course addresses the physical aspects of volcanoes, including such topics as the generation of magmas, styles of eruptions, products of eruptions, tectonic controls on the formation of volcanoes, and methods for predicting eruptions and mitigating the hazards associated with volcanic activity.

An optional field trip to an active volcano is possible. Mr. Walker.

Two 2- hour periods.

Prerequisites: Earth Science 151 or 161.

Not offered in 2011/12.

290a or b. Field Work (1/2 or 1)

297a. Readings in Earth Science (1/2)

297. Contemplating Time

Deep time, the concept of geologic time recognized by Persian polymath Avicenna (Ibn Sina) and Chinese naturalist Shen Kuo in the 11th century and developed further by James Hutton during the 18th century Scottish Enlightenment, has been called the single greatest contribution of geology to science. The concept provides a critical link between earth science and environmental change. Using reading and reflection, the aim of this course is to help students develop a feeling for the enormity of Earth???s duration in relation to human life spans. Students contemplate the nature of time from geoscientific, religious, and literary perspectives. Reading works by Loren C. Eiseley, Mircea Eliade, Malcolm Gladwell, Stephen Jay Gould, Abraham Joshua Heschel, Shunryu Suzuki, and Elie Wiesel, among others, we consider subjects such as the two great metaphors of time, arrows and cycles, in relation to natural and anthropogenic environmental change. The class meets weekly for contemplative practice and is suitable for students at any level. Ms. Schneiderman.

Prerequisite: permission of the instructor.

Not offered in 2011/12.

Year long course 300-301.

Permission of instructor is required.

311b. Continental Margins (1)

From oil to fisheries to mining operations, the continental shelf and slope environment house most of our offshore resources. Additionally the margins of the continents are hazardous, where earthquakes, landslides, tsunamis, turbidity currents, and storm waves challenge those who work and live there. This class investigates these processes and how they are preserved in the geologic record. Mr. McAdoo.

Prerequisite: Earth Science 251 or 211 or 271 or permission of the instructor.

One 4-hour classroom/laboratory/field session.

Not offered in 2011/12.

321a. Environmental Geology (1)

Topic for 2011-2012: Earth and Environmental Justice. In this course we explore the intersection of earth science with race, class, and gender in relation to environmental issues, past, present, and future. We examine the power of science and the responsibilities of scientists as we transform physical and human environments. Ms. Schneiderman.

Prerequisite: Earth Science 151 or 161.

One 4-hour meeting.

335b. Paleoclimatology: Earth's History of Climate Change (1)

(Same as Environmental Studies 335b.) This course discusses how Earth's climate system operates and what natural processes have led to climate change in the past. We examine the structure and properties of the oceans and atmosphere and how the general circulation of these systems redistributes heat throughout the globe. In addition, we study how cycles in Earth's orbital parameters, plate tectonics, and the evolution of plants have affected climate. Weekly laboratory projects introduce students to paleoclimatic methods and to real records of climate change. Ms. Menking.

Prerequisite: Earth Science 201, 211, and 231 or permission of instructor.

One 4-hour classroom/laboratory/field session.

340b. Arctic Environmental Change (1)

Not offered in 2011/12.

341a. Oil (1)

(Same as Geography 341a. and Environmental Studies 341a.) For the hydraulic civilizations of Mesopotamia, it was water. For the Native Americans of the Great Plains, it was buffalo. As we enter the twenty-first century, our society is firmly rooted both culturally and economically in oil. This class looks into almost every aspect of oil. Starting at the source with kerogen generation, we follow the hydrocarbons along migration pathways to a reservoir with a suitable trap. We look at the techniques geologists and geophysicists use to find a field, and how engineers and economists get the product from the field to refineries, paying particular attention to environmental concerns. What is involved in the negotiations between multinational corporations and developing countries over production issues? What are the stages in refining oil from the crude that comes from the ground to the myriad uses seen today, including plastics, pharmaceuticals, and fertilizers, not to mention gasoline? We also discuss the future of this rapidly dwindling, non-renewable resource, and options for an oil-less future. Mr. McAdoo, Mr. Rashid.

Prerequisite: One 200-level Earth Science course or permission of instructor.

One 4-hour classroom/laboratory/field session.

By special permission.

361a. Modeling the Earth (1)

(Same as Environmental Studies 361a.) Computer models have become powerful tools in helping us to understand complex natural systems. They are in wide use in the Earth and Environmental Sciences with applications in climate change research, prediction of groundwater and contaminant flow paths in sediments, and understanding the role of disturbance in biogeochemical cycling, among other applications. This course introduces students to conceptual modeling with the use of the Stella box-modeling software package. Taking readings from the scientific literature, we create and then perform experiments with simple computer models. Students also learn how to code their conceptual models in the programming language Fortran, one of the most widely used languages in the Earth and Environmental Sciences. Ms. Menking.

Prerequisite: 2 units of 200-level earth science.

One 4-hour classroom/laboratory session.

Not offered in 2011/12.

387a.Risk and Geohazards (1)

(Same as Environmental Studies and Geography 387a.)

The world is becoming an increasingly risky place. Every year, natural hazards affect more and more people, and these people are incurring increasingly expensive losses. This course explores the nature of risk associated with geophysical phenomena. Are there more hazardous events now than there have been in the past? Are these events somehow more energetic? Or is it that increasing populations with increasingly disparate incomes are being exposed to these hazards? What physical, economic, political and social tools can be employed to reduce this geophysical risk? We draw on examples from recent disasters, both rapid onset (earthquakes, tsunamis, cyclones), and slow onset (climate change, famine) to examine the complex and interlinked vulnerabilities of the coupled human-environment system. Mr. McAdoo.

One 4-hour meeting.

Prerequisites: Earth Science 121, 151, or 161.

Not offered in 2011/12
