AB: About 40 years ago (1968), when the US Naval research vessel Hunt surveyed in the East China Sea and Taiwan Strait, 3 leaders of the cruise (Emory, Wageman and Hilde, co-author of this paper) first discovered several thick sedimentary deposits forming the sub-basins. Some of these sedimentary sub-basins can be up to 9 kms thick. This was quickly translated to be a possible for the petroleum resource. The marine surveys of both the geological and geophysical fields in the East China Sea continental shelf have been increased significantly, even up to date. Our collections of the seismic, magnetic, gravity, and bathymetry data include the sources from Taiwan, USA, France, and Japan as well as from the commercial oil companies. The total seismic profiles alone can be up to 20,000 kms. This big data base has been gathered as a focus to better understand the tectonic structure, geological evolution, marine slope stability, and also be treated as an early tsunami warning system for the East Asia region. Some of the data can also be used to evaluate the local hydrocarbon potentials.
