What is Earth System Science?

Earth System Science is a study of composition and distribution of earth materials, structure of the Earth, tectonic mechanisms and the changes generated by these mechanisms. These disciplines are utilized in providing basis for the history and evolution of Earth, and to provide foundations for sustainable development, utilization and conservation of natural systems. With an increase in global interest for environmental preservation, resource development and development of earth information system, Earth System Science is developing into a multidisciplinary study leading the 21st century.

Department Introduction

Department of Earth System Sciences in Yonsei University seeks the following as its main goals:

  • Research of the creation of Earth, as well as ‘when’, ‘how’ and ‘why’ it was developed to its current state, to illuminate the history of Earth’s evolution.
  • Identification of Earth’s composition and structure from its crust to core.
  • Training of individuals who can apply their knowledge of the earth system to provide solutions for conservation, sustainable development and utilization of the “Earth Environment” in the near future.
Currently, the department is leading the field of Earth System Sciences by providing education and conducting researches on minerals, soils, rocks, moraine, geophysics, hydrogeology, applied geology, data processing, remote sensing, and other geologic fields. Research topics for the laboratories within the department are as follows.

Earth System Sciences Research Center (ESSRC) is leading the joint research between different academic disciplines. As a ‘university centered research laboratory’ designated by National Research Foundation of Korea, ESSRC is performing multidisciplinary studies on earthquake disasters, as well as providing solutions for numerous issues humanity faces today, including natural disasters, environmental maintenance and resource explorations. In addition, ESSRC endeavors to provide scientific explanations and recovery techniques for various factors with impacts on natural and anthropogenic environments.

Post-graduate Prospects and Career

Earth system science (ESS) allows for research of the Earth using approaches based on physical, chemical, biological, computational, mathematical and other disciplines. In addition, high applicability to structural engineering and civil engineering offers options for pursing a double major; hence, individuals studying ESS is given freedom in the choice of scientific approach used in their research, as any of these fields can play an essential role. Similarly, to the diversity of approach to understand ESS, the career choices from majoring ESS is diverse. In the case that a graduate decides to continue their academic career, they can continue doing so by participating as a professor or as a researcher, contributing to ongoing development of ESS. Alternatively, individuals may pursue a career in industrial field, with graduates working for government-owned organizations related to resource and energy (e.g. Korea National Oil Corporation and Korea Electric Power Corporation), engineering and construction groups for corporate entities (e.g. Samsung C&T, Hyundai Engineering & Construction, and SK E&C), environment-related research and industrial institutions, and information industries applying GIS and other satellite-based techniques.
