Preface

       This workshop is focused on thermodynamics of the oceanic environment which will be held in Xiamen, November 24-December 3, 2009. The main goal of this workshop is to bring the students from the fundamental concepts to the research frontier in large-scale wind-driven/thermohaline circulation and marine environment. The workshop consists of two parts: lectures by the principal lectures in the morning sessions and seminars on recent advances in this field by young scientists and students in the afternoon session. In addition, a trip to local tourist sites will be organized during the workshop.

         We have prepare a lecture note, in which a sensible balance is made between physical concepts fundamental to the oceanic circulation/environment, the well established theories, and the recent development associated with the frontiers in our field. Although theories about the oceanic circulation/environment have developed over the past several decades, it seems clear that our understanding remains rudimentary at the best. We have made a major effort in describing and explaining the physical/chemical/ecological aspects of the circulation/ environment, without relying on the sometime elaborate mathematics. To aid the readers, we have included many cartoons illustrating the physics/ chemistry/ ecology.

         We hope this lecture note will help students to understand the foundation of the modern theory of wind-driven/thermohaline circulation and global environment and move forward along this direction. This workshop will provide a forum of free exchanging and discussedion of scientific ideas between young scholars and students. We look forward to seeing many young students and scholars to join us in this workshop.
