The International Advisory Committee is the most important impetus for the establishment of the Department of Geological Oceanography. When the new department was established, Prof. James Tsu-Chien LIU, the IAC chair of DGO, felt very proud as a father experienced the birth of his child. Prof. Liu has acted as the IAC chair since 2013. Within 3 years, he has organized 3 IAC meetings gathering top scientists in marine scientific research field as the IAC members. These IAC meetings gradually formed DGO's development concept, department scale, research orientations and structure. At present, IAC will continue to play an important role in the research, discipline construction, talent introduction of the Department of Geological Oceanography.
