Research Status, Problems and Suggestions of Marine Environment Support for Deep Sea

The exploitation and construction of deep sea is a new direction for human development. In order to meet the national strategic development needs, it should be well planned in advance. Deep sea development is more dependent on the marine environment, and the demand for marine environment information is more urgent. This paper analyzed the fields in which the marine environmental service could play a role in the development and construction of deep sea and the corresponding service contents; from the aspects of navigation, hydrographic surveying and charting, and oceanographic survey, it analyzed the current status of the US and China's capabilities in deep sea marine environment support; then the gap between China and the United States in six aspects was analyzed; at last, some proposals were proposed from a disciplinary perspective.
