PhD in Earth, Ocean and Atmospheric Sciences


Program Description

Earth, Ocean, and Atmospheric Sciences (EOAS) provides fundamental knowledge that builds up our scientific realization and understanding of the earth system and changing trends. EOAS focuses on interdisciplinary and cross-disciplinary studies of interactions among ocean, atmosphere, and land in the earth system for the regional sustainable environment and climate change. It covers multidisciplinary study of physical, biogeochemical, earth surface science, and hydrology in the watershed and river-basin for the coupled systems of land-sea, air-sea, air-land, and land-sea-atmosphere interactions.

The Doctor of Philosophy (Ph.D.) Program in Earth, Ocean, and Atmospheric Sciences aims to provide rigorous training and research in EOAS that prepare students to face challenges of the changing earth system and the sustainable environment under changing climate in both regional and global scales.

A candidate for a Ph.D. degree is expected to demonstrate mastery of knowledge in the chosen discipline and to synthesize and create new knowledge, making an original and substantial contribution to the discipline.

Learning outcomes

On successful completion of the Ph.D. program, graduates will be able to:

  1. Identify and define the complex ideas and concepts of the interdisciplinary Earth, Ocean and Atmospheric System (EOAS);
  2. Recognize the power of abstraction and generalization and carry out original research in EOAS with sound independent judgment;
  3. Apply rigorous, analytical, highly numerical approach to analyze and solve problems of the earth system using the combined knowledge of EOAS;
  4. Transform effectively fundamental research insights into the earth and environmental science practice in relevant academic and engineering fields; and
  5. Exercise independent and critical communication skills to problems using the correct terminology and principle in the respective disciplines and their integrations in EOAS.
