The main research focuses on marine geochemistry, mineralization and submarine detection technology, resources and environment. During the "Tenth Five -Year" period, the group hosted a series of major projects from 973, 863, 703 National Special Projects, and more than 20 NSFC projects. The total grant funds are more than 41.7 million RMB Yuan. During the "Tenth Five -Year" period, one provincial-level scientific and technological progress award and two second-prize, 10 authorized patents, six published monographs (compiled, translated) and more than 30 papers published in high level of SCI or EI indexed journals. Deep-sea TV grab technology as a 863 result, is a deep-sea visualization intelligent sampling techniques as same as the international advanced level. In the investigation to the ocean, especially in 2005, it has played an important role in the economic benefits of 150 million RMB Yuan during "Ocean One" global scientific expedition, having a major impact at home and abroad.
The main directions are:
1. Marine Geochemistry
The direction is focusing on the establishment of experimental analysis methodology to marine geochemistry, focusing on modern seafloor hydrothermal activity, studying submarine rock geochemistry, isotope geochemistry and marine sedimentary geochemistry.
2. Submarine mineralization
From the view of the perspective of the distribution of seafloor mineralization systems, this direction is to study seabed cobalt-rich crusts, polymetallic nodules, hydrothermal sulfides and other mineral resources, occurrence, mineralization mechanism and metallogenic environment, and to highlight the comparison of the marine and continental metallogenics.
3. Surveying and sampling techniques to marine resources and environment
In recent years, the demand for technical investigations of submarine resources and the environment, the research and development of deep-sea series of sampling techniques of seabed samples, in particular the detection and study of deep-sea hydrothermal mineralization under extreme environment and biological genetic resources, require development of deep-sea implemented sampling techniques under extreme conditions for (high heat, high pressure, gas protection, pollution, etc. ) according to the needs of various types of samples quickly, easily and efficiently.
4. Deep-sea in-situ chemical sensor technology
For weak link to geochemical exploration of marine mineral resources (hydrothermal sulfide resource, natural gas-hydrate resources), this direction is to study non-contact in-situ chemical sensor technology of multiphase chemical compositions under deep-sea extreme environment, such as deep-sea in-situ laser Raman spectroscopy.
5. Experiment and simulation of modern seafloor hydrothermal activity and mineralization
To establish and improve laboratory experiments and numerical simulation for submarine mineralization, and to build experimental platform or facilities for studying submarine mineralization systems.
