On November 8, a post-voyage scientific symposium of the "Joint Arctic Scientific Middle-ocean ridge Insight Expedition, JASMInE for short” with Academician Li Jiabiao as the Chief Scientist was held online. The symposium was attended by over 30 people and was presided by Researcher Ding Weiwei. The attendee included internationally renowned scientific institution experts from Institut De Physique Du Globe De Paris (IPGP)(France), Alfred Wegener Institute (AWI)(Germany), University of Oslo(Norway), Queensland University of Technology(Australia), A.P. Karpinsky All-Russia Institute of Geological Research(VSEGEI)(Russia), University of Alaska, Memorial University of Newfoundland(Canada), Geological Survey of Canada, the JASMInE program team of SIO, etc.
        In the symposium, Academician Li Jiabiao introduced overall implementation of JASMInE program. Niu Xiongwei and Wang Yejian introduced respectively the measurement process and preliminary results of seabed earthquake exploration, hydrothermal solution and volcanic activities. Zhang Tao introduced ice-region seabed exploration technology as well as understanding and thinking from the aspect of geodynamics. The scientists attending the symposium conducted full exchanges and discussions with JASMInE program team on issues such as middle-ocean ridge lithosphere structure, hydrothermal solution activity, sub-glacial seabed exploration technology, historical data analysis and future Arctic seabed exploration voyage, etc.
        JASMInE program is the world first large scale comprehensive geological and geophysical survey of the sub-glacial middle ridge of Gac Ocean led by SIO, completing the last piece of puzzle of global middle-ocean ridge system. Academician Li Jiabiao expressed his gratitude to the scientists for their long-term support of JASMInE program, and proposed to further strengthen scientific cooperation on and deepen scientific understanding of the polar seabed. The scientists congratulated the successful implementation of JASMInE program site expedition, fully affirmed the existing preliminary results shared by our scientists, and believed that JASMInE program will be a significant contribution to the seabed and polar science community.
