Environmental Science

Undergraduate Program in Earth Systems Science

Earth Systems Science (ESS) examines the structure and function of the parts of the Earth's lithosphere, atmosphere, hydrosphere and biosphere and how these systems interact with one another. This integrated science, which focuses on connections between these Earth System components, is at the heart of some of our most pressing physical science and nature-societal issues, including global climate change, water availability, and the loss of biological diversity.

Clark's ESS program emphasizes the patterns and processes across the Earth's surface (to include both land and ocean) serving as an introduction to Earth sciences or Geosciences. Intensive field study, satellite remote sensing analysis, geographical information science (GISc), and computer simulation are all used as tools for understanding, monitoring, and predicting Earth System behavior. The ESS track of the Environmental Science major trains graduates for a wide range of professional endeavors as well as more advanced studies involving physical geography, to include landscape ecology, land-atmosphere interactions, hydrology, biogeochemistry, remote sensing, and GISc.

Comparison with Geography and other Environmental Programs at Clark

ESS is unique from other geographic and environmental science majors and concentrations at Clark. In comparing these areas of studies, keep in mind these factors:

  • ESS shares interests with but differs from the Environmental and Conservation Biology (ECB) track of the Environmental Science major (which is focused on ecosystems), and the Environmental Science & Policy (ES&P) concentration (which is focused on policy).
  • The ESS concentration differs from Clark's Global Environmental Studies (GES) major and the Human-Environment track of the Geography major because both of these programs are social science entries into environmental issues, not programs of study focusing on the biophysical functioning of the Earth System.
  • Majors in ESS not only develop strong biophysical training in Earth Systems Science, but also in analytical remote sensing and GISc tools that pervade this arena of science.
