Deep-sea exploration has made three important progress
According to this time, the acquisition of rich deep-sea geological samples and marine geophysical data has made three important progress in my country’s cobalt-rich crust contract area resources exploration, deep-sea geological survey, and the application of new technologies and methods for deep-sea exploration. First, a comprehensive geological and geophysical survey of the key survey areas of the Northwest Pacific Ocean was implemented, and full coverage of multi-beam water-deep terrain was achieved. Geophysical information and geological samples of rare earth-rich sediments were obtained, laying the foundation for the scientific research of deep-sea earth system science and the evaluation of new resources.
The second is to continue to carry out the annual resource survey of my country’s cobalt-rich crust contract area, fulfill the obligations of the “Cobalt-rich crust Exploration Contract” signed by the China Ocean Association and the International Seabed Administration. The survey results provide support for the resource evaluation of the cobalt-rich crust contract area and the successful completion of the regional abandonment tasks stipulated in the contract.
Cinema is a new technology innovation in deep-sea exploration. For the first time, the Komiks image processing technology is used to realize the intelligent splicing of underwater video images, providing basic data for the research on the distribution rules and characteristics of cobalt-rich crusts at a small scale; the detection performance of the in-situ acoustic thickness measurement system of cobalt-rich crusts was optimized, and it was successfully applied to multiple carrier platforms such as ROV and mobile drilling rigs, providing powerful investigation methods for fine detection of cobalt-rich crusts; and the stability and operating efficiency of cobalt-rich crust depth were improved.
The Messenger of China-Confucian friendship
In addition, during the berth of the Port of Ponape, the Federal Embassy in Micronesia on September 9, cooperated with the Chinese Federal Embassy in Mission to jointly hold a reception to commemorate the “30th Anniversary of the Establishment of Diplomacy between China and Mission” on the “Ocean Six” ship, and invited the federal politicians of the Michigan and related Chinese investment institutions. href=”https://funnybookish.com/”>Cinema representatives visited the Ocean VI ship and actively explored cooperation between China and Missouri in the fields of marine geology and other fields. The “Ocean VI” ship is the first modern comprehensive geological and geophysical survey ship independently designed and built by my country. In recent years, many of the newly listed marine scientific survey ships in my country have referred to the basic design of “Ocean VI”. Since its induction in 2009, Ocean VI has conducted 55 deep-sea geological, oceanic and polar scientific investigations in the South China Sea, the Pacific and Antarctic waters for 10 consecutive years. The cumulative sea trip has reached 2,137 days and safely sailed 290,000 nautical miles (about 53.Babaylan50,000 kilometers), the range is equivalent to circling the earth for 13 and a half circles. It has accumulated scientific investigation and navigation support experience in the entire sea area, and has significantly improved the scientific investigation level of marine geology in my country.
