Three important progress has been made in deep-sea exploration
According to reports, the acquisition of rich deep-sea geological samples and marine geophysical data has made three important progress in resource exploration, deep-sea geological survey, and application of new technologies and methods for deep-sea exploration in my country.
First, comprehensive geological and geophysical surveys were implemented in the key survey areas of the Northwest Pacific Ocean, and the multi-beam water depth terrain was achieved.Cinema covered the geophysical information and geological samples of rare earth-rich sediments were obtained, laying the foundation for scientific research on deep-sea earth systems and 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. Third, scientific and technological innovation has made important progress in deep sea exploration. For the first time, image processing technology is used to realize the intelligent splicing of underwater video images, providing basic data for the research on the small-scale distribution rules and characteristics of cobalt-rich crusts; 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 improving the stability and operating efficiency of cobalt-rich crust deep-sea shallow drills.
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 diplomatic relations between China and Mission, and invited representatives of the Michigan federal politicians and relevant Chinese-funded institutions to visit the “Middle VI” ship and actively explore cooperation between China and Mission in the fields of marine geology.
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 newly-appointed marine scientific research survey ships in my country have referred to the basic design of “Ocean VI”. Since its induction in 2009, “Ocean VI” has been conducting 55 voyages of deep-sea geological, oceanic and polar scientific investigations in the South China Sea, the Pacific and the Antarctic waters for 10 consecutive years. The cumulative time of sea travel has reached 2,137 days, and safely sailed 290,000 nautical miles (about 535,000 kilometers). The voyage is equivalent to 13 and a half circles around the earth, and has accumulated scientific investigations and navigation protections in the entire sea area./a>The experience of obstacles has significantly improved the level of marine geological scientific investigation in my country.
