The study details geological analysis of the South China Sea region. South China Sea is a marginal sea located in unique geographical region of west Pacific Ocean. It has a complex tectonics history being developed at subduction zone of three tectonic plates: Eurasian, Pacific and Indian. Geologically, South China Sea is rich in mineral resources and has high geological prospects. Within the scope of the study, the review of the general settings of the study area (bathymetry, geology, tectonics and sedimentation) is accomplished by the report on the current activities, methods and research clusters. Current directions in the marine geological research in the South China Sea area are presented. Research methods of the seafloor surveying and mapping currently undertaken in the South China Sea region are described: systematic measurement by multi-beam echo-sounders, altimetric measurements, GPS positioning, application of the unmanned underwater vehicles, GIS mapping, data analysis, dredging and drilling. The results include maps visualized by means of Generic Mapping Tools (GMT) showing geological and geophysical settings in the South China Sea region, bathymetry and model of the marine free-air gravity. Research development and recent progress in marine geologic investigations are reported with focus on current activities in the coastal area of the South China Sea region.

The study is geographically focused on the Manila Trench, located in the west Pacific Ocean, South China Sea, west Philippines. The research aims at the geological mapping, analysis and visualizing variations in the submarine geomorphology of the Manila Trench. Technically, the work was done using Generic Mapping Tools scripting toolset (GMT). A combination of various GMT modules was applied for geospatial modelling. Methodology includes cartographic data integration and interpretation through approaches of data analysis: topographic plotting, geophysical modelling, geological mapping and statistical analysis. The data included SRTM, ETOPO1, geoid and gravity grids (CryoSat-2, Jason-1). Two sets of the cross-section profiles of the trench were automatically digitized. The profile transects were compared and differences in the geomorphic shape in southern and northern parts revealed. Southern part has steeper slope on the western part. Northern part is steeper on the continental slope part. The submarine terraces are located on the northern segment at depths -2,000 m. The depth and geomorphology of the slope vary for the range -3,500 to -4,500 m: minimals for the northern part with 526 samples (18.2%) for the depths -4,000 to -4,200 m. The histogram for the northern part has bimodal distribution with two peaks. The southern part shows 142 values for the minimals -3,500 to -3400 m. The statistical analyses revealed that northern part of the trench is deeper. The GMT functionality shown in this paper enabled integration and interpretation of the multi-source data: automatically digitized profiles, geological mapping, 2D and 3D bathymetric modelling, statistical analysis, mathematical approximation of the trend modelling. The GMT proved to be capable of visualizing geodata that can significantly improve Earth studies and interpretation of submarine geomorphology of the oceanic trenches through the advanced data analysis.

Geology of the China Seas represents the first English-language synthesis of the available research into the geology of the South and East China Seas. Among the marginal basins worldwide, these areas have been the focus of extensive research activities in the last three decades, and are now among the global hot spots in hydrocarbon explorations and scientific investigations. The region is experiencing rapid economic development with the offshore petroleum industry providing approximately one third of the domestic hydrocarbon production for mainland China. Gas hydrates have been successfully recovered from the China Seas for the first time. Over the years, many volumes on the geology of the China Seas have been published in Chinese. Although an increasing number of papers in English have appeared recently, the majority deal with local or regional paleo-environment and sedimentology, and are scattered in different journals. This book brings together this rich data in one resource, particularly that generated by Chinese marine geologists and petroleum geologists, and provides the very first synthesis of the geology off China. The first systematic summary of the geology of the China Seas Includes comprehensive coverage of the South China Sea and the East China Sea, including the Yellow Sea and Bohai Gulf Reviews hundreds of Chinese publications on marine and petroleum geology not currently accessible to the international community

The waters and rich resources of the South China Sea are claimed by seven different countries, and it is estimated that approximately 40% of the world’s trade moves through the area. Marine Geology and Geotechnology of the South China Sea and Taiwan Strait examines the physiology, geology, and potential development of this important portion of the western Pacific Ocean’s largest marginal sea. The book covers multiple oceanographic topics, and further discusses topography, sedimentation, wave generation, and hazards such as earthquakes, storm surges, and tsunamis. In addition, it explains the engineering issues and design considerations involved regarding a potential Taiwan Strait Crossing, as well as the development of near-shore communities. Features: Examines seabed material, such as clays, calcareous, siliceous, and various other organic sediments Presents different potential routing strategies for sea crossings using tunnels, bridges, or a combination of both Provides bridge design recommendations considering aesthetics, seismic and wind issues, potential vessel collisions, and more Includes a historical timeline and useful maps regarding the political complexity of the area and the various territorial claims made by different nations Marine Geology and Geotechnology of the South China Sea and Taiwan Strait serves as a valuable resource for geotechnical engineers, marine geologists, civil engineers, and professionals concerned with the region.

Pinxian Wang and Qianyu Li The South China Sea (SCS) (Fig. 1. 1) offers a special attraction for Earth scientists world-wide because of its location and its well-preserved hemipelagic sediments. As the largest one of the marginal seas separating Asia from the Paci?c, the largest continent from the largest ocean, the SCS functions as a focal point in land-sea int- actions of the Earth system. Climatically, the SCS is located between the Western Paci?c Warm Pool, the centre of global heating at the sea level, and the Tibetan Plateau, the centre of heating at an altitude of 5,000m. Geomorphologically, the SCS lies to the east of the highest peak on earth, Zhumulangma or Everest in the Himalayas (8,848m elevation) and to the west of the deepest trench in the ocean, Philippine Trench (10,497m water depth) (Wang P. 2004). Biogeographically, the SCS belongs to the so-called “East Indies Triangle” where modern marine and terrestrial biodiversity reaches a global maximum (Briggs 1999). Among the major marginal sea basins from the west Paci?c, the SCS presents some of the best conditions for accumulating complete paleoclimatic records in its hemipelagic deposits. These records are favorable for high-resolution pa- oceanographic studies because of high sedimentation rates and good carbonate preservation. It may not be merely a coincidence that two cores from the southern 14 SCS were among the ?rst several cores in the world ocean used by AMS C dating for high-resolution stratigraphy (Andree et al. 1986; Broecker et al. 1988).
