On September 7, Key Laboratory of Submarine Geosciences, SOA, the Department of Earth Sciences of the University of Cambridge, UK, the Natural Disaster Research Center of University Malaysia Sabah and the Institute of Geology and Geophysics of Chinese Academy of Sciences signed a cooperation agreement on the OBS voyage for exploring the deep area of trough of the South China Sea and Nansha Sea.
According to the general view of the geosciences circles, prior to the formation of the present South China Sea, there was the “ancient South China Sea” to the south of the continental margin in the southern part of China. The subduction of the ancient South China Sea to Borneo in the Nansha trough area caused the extension and breaking of the present South China Sea continental margin and the floor spreading in the South China Sea. The eventual collision of the Nansha block drifting southwards with Borneo ended the expansion of the South China Sea. Therefore, the Nansha trough area recorded the information about how the South China Sea was born and dead, and is important to the study of the structure of the deep area and kinetic mechanism.
Under the special support of the State Oceanic Administration themed "Global Change and Air-sea Interactions", Key Laboratory of Submarine Geosciences and the Institute of Geology and Geophysics of the Chinese Academy of Sciences will launch the OBS voyage for exploring the deep area of trough of the Nansha Sea from 2018 to 2019. They will also carry out cooperation with the Department of Earth Sciences of the University of Cambridge and the Natural Disaster Research Center of University Malaysia Sabah based on the previous Sino-Malaysia Maritime Cooperation Platform.
During the two-day exchange, the three parties – China, UK and Malaysia, discussed the time of the voyage, and the technical details such as the layout of the site and survey lines, launch and collection, and agreed that China will be responsible for the implementation of the OBS voyage at sea for this international cooperation, the UK side for the exploration of the deep structure of the land, and the Malaysian side for obtaining the approval of the voyage operations from the Malaysian government. On this basis, the four parties formed an international cooperation agreement on the implementation of the voyage, the responsibilities and obligations of all parties, data sharing, follow-up cooperation and other details. Fang Yinxia, director of the Key Laboratory of Submarine Geosciences, SOA, Hao Tianyao, a researcher at the Institute of Geology and Geophysics of the Chinese Academy of Sciences, Felix Tongkul, a professor at University Malaysia Sabah, and Nicholas Rawlinson, a professor at University of Cambridge, UK, signed the agreement.
In the next three years, China, UK and Malaysia will carry out voyage and follow-up cooperation on the basis of the international cooperation agreement. It is estimated that for the first time, deep seismic data from the Nansha Sea area to Borneo will be obtained. Indeed, there are some key scientific issues such as the subduction of the “ancient South China Sea", the mechanism of collision between Nansha block and Borneo and the uplift of the Sabah orogenic belt in Borneo, that can be figured out through the jointly research.
During the visit, Professor Nicholas Rawlinson and Professor Felix Tongkul respectively delivered a speech on "origin of the modern intraplate volcanism in Eastern Australia – inspiration from seismic tomography and dynamics simulation" and "research on rock stratum unit of Borneo of Malaysia in the ancient South China Sea”.
