The 6th International Conference on Asian Marine Geology will be held on 29th August through 1st September, 2008, in Kochi, Japan. Since the 1st Conference in Shanghai, China in 1988, the twenty years have passed, during this period, the conference provided good opportunity to exchange ideas and new information, and helped in planning for future collaboration to promote better understanding of marine geology and its related science in the Asian waters. Simultaneously literacy for the scientific issues that we will discuss in this meeting has been significantly improved within the society. Moreover the community that surrounds us has surely grown, and a new technology has been introduced into our scientific field. We will hold the conference at such exciting time. We sincerely invite you to participate in and enjoy in conference by bringing your ideas and research plan to discuss and share, make collaboration with the others.
