Ocean mineral and hydrocarbon deposits are major resources to ensure a sustainable industrial development in the future. In order to provide an open platform for the advancement of global marine resources exploration and development technology, the 9th International SUT (China) Technical Conference and the 1st SUT/SEG Marine Resources Exploration and Development Technology Symposium will be jointly held in Changsha, China,from January 6 to 8, 2021. We would like to extend our warmest invitation to experts and scholars from home and abroad engaged in scientific research,education, production, application and other disciplines to discuss the development of underwater technology, engineering equipment and related  industrial topics.

Founded in 1966 and headquartered in London, United Kingdom, the Society for Underwater Technology (SUT) is the most influential academic organization in the world of underwater engineering and is a multidisciplinary society that brings together institutions and individuals concerned with underwater technology, marine science and marine engineering. The SUT Technical Conference was initiated by SUT China Branch and 8 sessions have been successfully held since 2012 in Shenzhen, Shanghai, Qingdao, Beijing,Haikou and Zhoushan, which have been highly recognized by experts and scholars.

Founded in 1930 and headquartered in Tulsa, Oklahoma, USA, the Society of Exploration Geophysicists (SEG) is a technical organization dedicated to promoting the development, progress and innovation of Applied Geophysics. It has more than 33,000 members worldwide from 138 countries.SEG has trained a large number of geophysicists in the exploration and development of natural resources,

characterization of near surface features and mitigation of earth hazards. SEG organizes the world's largest Geophysics Congress every year and achieves its mission through publications, conferences, forums, online resources and educational opportunities. SEG China was established in April 2008 in Beijing, which is the first branch of SEG outside the United States. It serves members of China and all projects in China and provides targeted services according to Chinese market conditions.

For the first time, the symposium of marine resources exploration and development technology takes the opportunity to implement national strategies and promote the economic development of Hunan. It will be held in Changsha.This symposium targets to discuss ways to effectively carry out the transformation and upgrading of related engineering machinery and equipment for marine resources exploration and development, improve the quality of personnel training, enhance the ability to serve the local economy and further the sustainable use of marine engineering equipment and resources in the future. It provides a platform for domestic and international experts and scholars to discuss.This conference will be held in Changsha city, which is rich in historical heritages such as old wall remains and ancient tomb sites. It is also considered to be the cradle of Huxiang culture. Changsha Research Institute of Mining and Metallurgy is the first company to be involved in the development of deep sea mining technology in China. It has undertaken major and key scientific research and built a State Key Laboratory of Exploitation and Utilization of Deep Sea Mineral Resources and an International Joint Research Centre for the Development of Seabed Mineral Resources. It is a major innovation base for the exploration and development of deep-sea mineral resources, marine technology development and international cooperation.
