Abstract: From October 20 to 24, 2016, the International Symposium on Marine Engineering Geology was successfully held in Qingdao, China. It was the first symposium on marine engineering geology sponsored by the Marine Engineering Geology Commission of International Association for Engineering Geology and the Environment. The theme of this symposium was marine engineering geology and geo-environmental safety. Six topics were set for this symposium, including engineering characteristics of marine soil, regional engineering geology and offshore geohazards, coastal engineering geology, marine engineering geological survey technology and data analysis, submarine soil-structure interaction, and marine engineering geology in offshore new energy development. It had 13 plenary reports, 57 ordinary oral reports and 15 poster reports. It provided a board platform for domestic and foreign experts to communicate with each other deeply and widely, and reflected our country's academic position and appeal in the international academia of marine engineering geology. Though great progress has been made in marine engineering geology, it was still in their infancy both in China and around the world. Researchers on marine engineering geology should concentrate on the new difficulties and hotspots in ocean engineering, responding to the demand of national strategies.
