Abstract

With the continuous exploiting of terrestrial mineral resources, submarine mineral becomes a potential replacement to support social modernization and economic development in the near future. As we all known, a great strategy of maritime development has been presented since the beginning of the 21st century by our state leaders. Hence, it is very necessary to increasingly utilize the seabed mineral resources buried in South China Sea (SCS), and the first is to reevaluate the distribution and reserves of submarine mineral resources. So, based on abundant of geological materials and literature search after years of collecting by authors, this paper summarized the research status of seabed mineral resources in SCS, including the latest surveying results by manned Deep-Submergence Vehicle (DSV) and Remotely-Operating Vehicle (ROV), and revealed mineral characteristics and distributing regularity of manganese nodules, cobalt-rich crusts, polymetallic sulfides, rare earth deposits, sand minerals and other types of resources. Meanwhile, the mineralization prospects of various types of minerals were reevaluated and the potential problems in the development of seabed mineral resources were analyzed. In this way, the potential research of seabed mineral resources will be strengthen, national requirement of mineral exploitation in SCS will be gradually satisfied, and relevant basic materials for government decision-making will be effectively provided for reference.

The South China Sea is the sea area with the largest area, the largest depth, the most abundant oil and gas resources and the most comprehensive biological species in China. The further exploration of the South China Sea with manned submersible and other major deep-sea equipment is of great significance to China's deep-sea scientific investigation. In this paper, Jiaolong manned submersible was taken as an example. In order to explore the operation window to guarantee the operation safety of manned submersible and improve the efficiency of voyage scientific investigation, this paper combined the global wave return data and the wave data based on satellite remote sensing to focus on the Marine environment characteristics in the South China Sea. According to the operational design parameters of Jiaolong, in the South China Sea, the most appropriate operating time window is from April to September, and the rest of the time, proper sea conditions should be selected for the operation.
