Earth System Science (ESS)

On this Page: Major Description | Requirements | Learning Objectives

The ESS Major

student with water sample in tubeThe Bachelor of Science in Earth System Science (ESS) offers an interdisciplinary approach to understanding how our planet is shaped through natural and human processes. Students explore the intersection of critical geophysical, biogeochemical, and socio-environmental processes through courses that address the challenges of living on a rapidly changing planet.

ESS students learn to apply systems thinking, spatial analysis, and other natural and social science methodologies as they examine the interactions among humans and earth systems, evaluate the sustainability and resilience of living and built systems, and design solutions to our biggest environmental challenges. The ESS major features experiential learning that takes place in natural environments. These emphases on field work and the human dimensions of the earth system are the unique characteristics of the UW Bothell ESS degree.

The ESS degree program is jointly administered by the School of Interdisciplinary Arts & Sciences (IAS) and the School of Science, Technology, Engineering & Mathematics (STEM). with teaching and research contributions from faculty members in both schools.

Learning Objectives

ESS graduates will be expected to demonstrate advanced achievement of the UW Bothell Learning Goals, and the Learning Objectives of both IAS and STEM. In addition, the ESS Program is designed to provide a curriculum and co-curricular opportunities that will specifically enable graduates to:

Function as Earth System Scientists

  • Demonstrate a foundational understanding of mathematics, chemistry, biology, and/or physics, along with an advanced understanding of geoscience.
  • Apply their multi-disciplinary understanding to characterizing aspects of the Earth system and critically evaluating Earth system science information, models, and methods.

Master Systems Thinking

  • Analyze complex phenomena or problems in the Earth sciences and place them in the context of holistic systems, identifying their components, interconnections, critical thresholds, and leverage points for enhancing system function and environmental justice.

Function as Independent Interdisciplinary Scholars

  • Apply their understanding of Earth system science, the scientific method, and interdisciplinary inquiry in generating research questions and selecting methods for assessing hypotheses, evaluating data, and creating knowledge.
  • Generate a data collection plan and synthesize information derived from observations, experiments, models, and scholarly readings.
  • Critically reflect on what they are learning in their courses and research and make claims of their learning gains and research findings that are supported by evidence.

Integrate Social Science and Natural Science Epistemologies

  • Demonstrate understanding of how human civilization interacts with Earth systems at multiple scales and how Earth system science relates to and informs management and policy objectives.
  • Relate how differing conceptions of ethics, human-nature relationships, structural inequities, and the objectives of sustainability and resilience inform evaluations of Earth system challenges and alternative solutions.

Communicate Effectively and Inclusively

  • Generate graphics, reports, and presentations in ways that are appropriate and educational for their intended audience (e.g., other scientists, policy makers, and the general public).
  • Interact and communicate with others in ways that are inclusive and manifest a respect for diversity in all its forms.

Collaborate and Share Leadership

  • Demonstrate an advanced ability to work with partners and in groups, including the capacities for taking and sharing leadership, following through on collective decisions, promoting the potential of all group members, and mediating conflict.
  • Engage in projects with external partners in a fashion that adheres to the highest standards of professionalism and results in mutually beneficial outcomes.
  • Engage with diverse agencies, communities, and other groups with an understanding of the many cultural, geographic, socio-economic, and political contexts in which people interact with Earth systems.
