Abstract: Since the 1980s of the 20th century, the development of new theories in marine geosciences as well as significant new breakthroughs in seafloor geological survey and mineral resource exploration are mainly attributed to the adoption of high technologies and diverse probing instruments featured by high resolution, high performance and high precision. Obviously, the application of high technologies has been greatly promoting the development of marine geosciences, including the seafloor spreading doctrine and plate tectonic theory, sedimentation and turbid currents, the cause of formation on earthquakes and volcanoes, paleo-oceanography, global change, modern mineralization theory in seabed, extreme environment and biodiversity, and the hypothesis on underground biosphere. This paper summarizes the development status of the global positioning systems at home and abroad, new 3D marine mapping technologies, seafloor geological sampling technologies, deep-sea systems for detecting and exploiting mineral resources, and deep-sea delivery technologies, as well as the general situation of China's deep sea technologies. Finally, this paper suggests that an overall set of comprehensive 3D probing system be established to facilitate the progress of marine geosciences in China.
