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 BIOL 105  and BIOL 106 ; CHEM 108 /CHEM 109  or CHEM 125 ; PHYS 113  and PHYS 114 ; and MATH 101  and MATH 102  or MATH 121 /MATH 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: Kirsten Menking, Jill S. Schneiderman, Jeffrey Walker.

• ESCI 100 - Earth Resource Challenges

  
  1 unit(s)

  ---

  (Same as ESSC 100 , ENST 100 , and GEOG 100 ) This course combines the insights of the natural and social sciences to address a topic of societal concern. Geographers bring spatial analysis of human environmental change, while Earth scientists contribute their knowledge of the diverse natural processes shaping the Earth’s surface. Together, these distinctive yet complementary fields contribute to comprehensive understandings of the physical limitations and potentials, uses and misuses of the Earth’s natural resources. Each year the topic of the course changes to focus on selected resource problems facing societies and environments around the world. When this course is team-taught by faculty from Earth Science and Geography, it serves as an introduction to both disciplines.
  
  Open only to first-year students; satisfies college requirement for a First-Year Writing Seminar.
  
  Two 75-minute periods.

• ESCI 109 - Hot Topics in Earth Science and the Media

  
  1 unit(s)

  ---

  From fracking to mountaintop removal, BP’s Gulf of Mexico oil spill, invasive species and their impacts on native ecology, and global warming, geology and related ecologic processes have been major topics in the news lately. This course examines the science behind different natural processes and phenomena (e.g. How do coal beds form? What makes a particular stratigraphic level potentially valuable for hydraulic fracturing? What do we know about responding to oil spills? What does the paleontological record tell us about species invasions?) and also examines media portrayals of these hot-topic issues. Students gain a deeper understanding of the scientific community’s knowledge on these issues and develop the ability to assess whether or not media coverage is fair and accurate. We also discuss how science itself is portrayed in the media and the importance of accurate and accessible scientific communication.

• ESCI 111 - Science and Justice in the Anthropocene

  
  1 unit(s)

  ---

  (Same as GEOG 111  and STS 111 ) Geoscientists have proposed a new designation in the geologic time scale for our current time period, “the Anthropocene.” The designation reflects the fact that human beings are acting as geological agents, transforming the Earth on a global scale. In this first-year seminar course we explore the possibilities of reconfiguring the actions of humans in the Anthropocene so as to lead to a flowering of a new Era once called ‘the Ecozoic’ by cultural historian Thomas Berry.

• ESCI 135 - Volcanoes and Civilization

  
  1 unit(s)

  ---

  Few natural phenomena are more spectacular than a volcanic eruption. Volcanoes have been an important part of human culture throughout history whether in legends or in actual events. Through accounts of volcanic events, such as Plato’s account of the legend of Atlantis, recent scientific analysis of the eruption of Vesuvius and the destruction of Pompeii, or news media coverage of current eruptions, this course studies the role volcanoes have played in society as it traces the historical development of volcanological study using sources such as classical literature, nineteenth century treatises in natural science, modern scientific journals, and the popular media.
  
  An optional field trip to an active volcano is possible.
  
  Two 75-minute periods.

• ESCI 151 - Earth, Environment, And Humanity

  Semester Offered: Fall
  1 unit(s)

  ---

  (Same as GEOG 151 ) Catastrophic events such as hurricanes and tsunamis and the specter of global climate change affirm the centrality of Earth Science in a well-rounded liberal arts education. Understanding past events helps us comprehend what has happened and predict future events. In this course we examine past events and current natural processes to understand how this past and these processes affect human and other beings. We explore topics such as minerals and rocks, natural hazards and disasters, and changes to the hydrosphere and atmosphere over time. To do so, we learn some underlying principles of the natural world, from small things like the very building blocks of matter (atoms), to large things, like the cause and effect of regional forces that build mountains and make new oceans. The course takes a hybrid approach, partly as a normal lecture in the classroom during our meeting time, and partly as a lab/field trip/discussion. While serving as an introduction to the Earth Science major, this course emphasizes those aspects of the science that everyone should know to make informed decisions such as where and where not to buy a house, whether to support the construction of an underground nuclear waste repository, whether to build on floodplains and along coasts, and how to live more lightly on Earth. Jill Schneiderman.
  
  Several lab exercises take place in the field.

• ESCI 203 - Earth History

  Semester Offered: Fall
  1 unit(s)

  ---

  In this course we study the methods and principles employed in deciphering the geologic history of Earth and the development of life on the planet. We emphasize the geologic evolution of the North American continent and the main features of the fossil record. Students learn to recognize the patterns of both biologic and tectonic evolution of Earth through time, from the Archean to the present. Woven throughout the course is consideration of the history of geologic thought through examination of the ideas of James Hutton, Charles Lyell, Charles Darwin, and Alfred Wegener.  John Zayac.

• ESCI 220 - Cartography: Spatial Data Visualization with GIS

  Semester Offered: Fall
  1 unit(s)

  ---

  (Same as GEOG 220 ) Geographic information systems (GIS) give us the ability to display and analyze data, and thus give us broader perspectives on social and environmental processes and patterns. Map-making and communication with spatial data are therefore fundamental aspects of Geography. This course uses GIS to make thematic maps and to acquire and present spatial data in diverse ways. In addition, we explore the culture, politics, and technology of historical cartography, and we examine how maps have been used as rhetorical and political texts. Throughout the course, we focus on strategies for clear, efficient, and intentional communication through graphic presentation of data. Thus, the course integrates problems of design, esthetics, and communication with techniques for manipulating quantitative data. In the final project, students apply ideas to a topic of their individual interest. ArcGIS is used in labs for map production and data analysis. Mary Cunningham.
  
  Prerequisite(s): One 100-level Geography or Earth Science course, or permission of the instructor.

• ESCI 221 - Soils

  Semester Offered: Fall
  1 unit(s)

  ---

  (Same as GEOG 221 ) Soils form an important interface between the lithosphere, hydrosphere, atmosphere, and biosphere. As such, they are critical to understanding the functioning of ecosystems. This course studies soil formation, and the physical and chemical properties of soils critical to the understanding of natural and constructed ecosystems. Field trips and laboratory work focus on the description and interpretation of local soils.  Jeffrey Walker.
  
  Prerequisite(s): One introductory course in Biology, Chemistry, Earth Science; or ENST 124 .
  
  Two 75-minute periods; one 4-hour laboratory/field period.
  
  Course Format: CLS
• ESCI 224 - GIS: Spatial Analysis

  Semester Offered: Spring
  1 unit(s)

  ---

  (Same as GEOG 224 ) Geographic information systems (GIS) are increasingly important and widespread packages for manipulating and presenting spatial data. While this course uses ArcGIS, the same software as Cartography, the primary focus here is spatial analysis (calculating patterns and relationships), rather than map design for data visualization. We explore a variety of techniques for answering questions with spatial data, including overlay, map algebra (math using multiple input layers), hydrologic modeling, surface interpolation, and site selection. Issues of data collection through remote sensing and sampling are addressed. GIS involves a more rapid introduction to the software than Cartography does; it is useful to take both Cartography and GIS (preferably in that order) to gain a more complete understanding of spatial data analysis and manipulation.  Mary Ann Cunningham.

  Two 75-minute periods; one 2-hour laboratory.
  
  
• ESCI 226 - Remote Sensing

  
  0.5 unit(s)

  ---

  (Same as GEOG 226 ) Many key environmental questions today are studied at least in part with remotely sensed data. Imagery from satellite sensors, such as LandSat, or airborne sensors, provide insights into questions regarding oil spills, sea ice extent, agricultural land uses, urban expansion, deforestation, forest health, weather, and many other phenomena. This 6-week course provides a short introduction to remotely sensed data, including principles of image capture, e.g., radiative energy, electromagnetic spectra, and spectral signatures, and basic approaches to image classification and interpretation. Using accessible image interpretation software, we practice different approaches for using imagery to address environmental questions. This course complements GIS, Cartography, and other courses concerned with mapping and land change analysis. It has no prerequisites, but willingness to explore new software and data is important.

• ESCI 231 - Geomorphology: Surface Processes and Evolution of Landforms

  
  1 unit(s)

  ---

  (Same as GEOG 231 ) Quantitative study of the physical, chemical, and biological processes that create Earth’s many landforms. Topics include weathering and erosion, landsliding and debris flows, sediment transport by rivers and glaciers, the role of climate in landscape modification, and the use of landforms to document earthquake hazards. Lab exercises emphasize fundamental skills in geomorphologic analysis such as mapping, surveying, interpretation of aerial photography, and use of Geographic Information Systems software.

• ESCI 235 - Water

  
  1 unit(s)

  ---

  (Same as GEOG 235 ) Sixty to seventy percent 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.

• ESCI 251 - Global Geophysics and Tectonics

  Semester Offered: Spring
  1 unit(s)

  ---

  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.  John Zayac.

• ESCI 254 - Environmental Science in the Field

  
  1 unit(s)

  ---

  (Same as ENST 254 ) 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.

• ESCI 260 - Conservation of Natural Resources

  
  1 unit(s)

  ---

  (Same as GEOG 260 ) Natural resources are perennially at the center of debates on sustainability, planning, land development, and environmental policy. The ways we conceptualize resources can be as important to understanding these issues as their actual distributions are. This course provides a geographic perspective on natural resource conservation, using local examples to provide deeper experience with resource debates. We focus particularly on forest resources: biodiversity, forest health, timber resources, forest policy, and the ways people have struggled to make a living in forested ecosystems. We discuss these issues on a global scale (such as tropical timber piracy and forest conversion), and we explore them locally in the Adirondacks of New York. This course requires that students spend October Break on a group study trip in the Adirondacks. Students must be willing to spend long, cold days outside, including some strenuous physical activity (unless special permission is arranged with the instructor). 
  
  Students wishing to register under Earth Science must have had at least one previous earth science course.

• ESCI 271 - Structural Geology: Deformation of the Earth

  
  1 unit(s)

  ---

  Structural geology explores the deformation of Earth’s crust caused by the movement of its tectonic plates and the resulting structures that are produced at scales ranging from the microscopic to the mountainous. It underpins the oil and gas industry and mining because fossil fuels and precious metals are commonly associated with folds and faults. It is also important in earthquake and landslide hazard prediction. Lab exercises emphasize the fundamentals of geologic mapping, how to use geometric principles to predict what lies in the subsurface from surface observations, and how rocks behave under varying conditions of stress. Many exercises occur in the field. 
  
  Prerequisite(s): ESCI 151  or permission of the instructor.
  
  Satisfies the college requirement for quantitative reasoning.

• ESCI 275 - Paleontology and the Fossil Record

  
  1 unit(s)

  ---

  (Same as BIOL 275 ) Paleontology isn’t just a “dead science”- by studying processes that have occurred in the past, we can deepen our understanding of the current biota inhabiting the Earth. Conversely, by studying the modern distribution of organisms and the environmental, taphonomic, and ecological processes that impact their distribution and preservation, we can enhance our understanding of the processes that have controlled the formation and distribution of fossils through time. In this course, we explore the methodology used to interpret the fossil record, including preservational biases and how we account for them when studying fossil taxa. We also explore large-scale ecological changes and evolutionary processes and discuss how they manifest across geologic time, and how these relate to Earth’s changing fauna. We additionally learn about how paleontology has developed as a field in the context of different historical and social perspectives. Lab exercises focus on applying paleontological methods to a variety of different fossil and recent samples.  To Be Announced.

• ESCI 277 - Biogeochemistry

  Semester Offered: Spring
  1 unit(s)

  ---

  Our planet is uniquely suited in our solar system to support complex life. In turn, the engines of biology have altered Earth’s geochemistry in ways that have allowed for the development of higher animals and the establishment of a relatively stable climate system. How do Earth’s biology, chemistry, and geology work together to create the Earth System we know today? Throughout the course we explore case studies from Earth History such as the oxygenation of the atmosphere, the colonization of the continents by land plants, and the advent of calcifying organisms. Lab and field exercises give us a chance to collect and analyze biogeochemical data. In the process, we cement our understanding of biogeochemical cycles and how humanity is altering them today.

• ESCI 297 - Readings in Earth Science

  
  0.5 unit(s)

  ---

  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.

• ESCI 325 - Mass Extinctions

  Semester Offered: Fall
  1 unit(s)

  ---

  It is often argued that our planet today is undergoing the “sixth mass extinction”. What defines a mass extinction in the rock record? What forces are able to cause such immense destruction of life on Earth? And, what are the outcomes of mass extinction for life on the planet? In this course we use the geologic record as our guide to understanding the consequences of asteroid impacts, rapid greenhouse gas emissions, and glaciation for the Earth System. We also explore ongoing controversies in the scientific literature regarding the cause of these catastrophic events. In group discussions, we probe the ways that the context of past mass extinctions can be used to inform conservation policy. Laura Haynes.

• ESCI 335 - Paleoclimatology: Earth’s History of Climate Change

  
  1 unit(s)

  ---

  (Same as ENST 335 ) In recent decades, record high temperatures and extreme weather events have led scientists and policy makers to grapple with the fact that human activities are affecting the climate system. At the same time, scientists have come to realize that climate is capable of dramatic shifts in the absence of human intervention. The science of paleoclimatology seeks to understand the extent and causes of natural climatic variability in order to establish the baseline on top of which anthropogenic changes are occurring. In this course we examine the structure and properties of the oceans and atmosphere and how the general circulation of these systems redistributes heat throughout the globe; study how cycles in Earth’s orbital parameters, plate tectonics, changes in ocean circulation, and the evolution of plants have affected climate; and explore the different lines of evidence used to reconstruct climate history. Weekly laboratory projects introduce students to paleoclimatic methods and to records of climatic change from the Paleozoic through the Little Ice Age.

  (Same as ENST 361 ) Computer models are powerful tools in the Earth and Environmental Sciences for generating and testing hypotheses about how the Earth system functions and for allowing simulation of processes in places inaccessible to humans (e.g., Earth’s deep interior), too slow to permit observation (e.g., erosion driven uplift of mountains ranges), or too large to facilitate construction of physical models (e.g., Earth’s climate system). Taking readings from the scientific literature, we create and then perform experiments with simple computer models, using the STELLA iconographic box-modeling software package. Topics include the global phosphorus cycle, Earth’s radiative balance with the sun and resulting temperature, the flow of ice in glaciers, and the role of life in moderating Earth’s climate. Toward the end of the semester, students apply the skills they have acquired to a modeling project of their own devising.
