Introduction
Its research areas cover China’s marginal seas, the Pacific Ocean, the Indian Ocean, the Atlantic Ocean and Polar Regions. Being equipped with advanced devices for sea bottom survey and testing studies, researchers in this laboratory have the ability to independently investigate submarine topography, integrated geophysics, submarine earthquake, and comprehensive geological and sediment environment. Six specialized laboratories were established for rock, sedimentation and isotope analysis, for technology research and development and for interpretation of sediment acoustics and comprehensive geophysics, thus forming our own distinctive features in these areas.
