GLOBAL ADVANCE OF DEEP-SEA TECHNOLOGY

Since the 1960s,deep-sea technology has got great progress in developed countries,for instance,the research vessels,drilling platforms,survey instrument and equipment,AUV/HOV/ROV,submersibles,corers and samplers,and seabed monitoring systems.The advance of technology makes scientists possible to probe the unknown part under the ocean in wider range and deeper depth,in particular in the fields of deep-sea extreme environment,earthquake mechanism,deep-sea biology,mineral resources,and deep water deposits and structures.In this paper,we briefed the major achievements of deep water technology in the USA,Japan,Brazil,Russia,European counties,South Korea and China.
