Jinyang.com News Reporter Zhao Yanhua Correspondent Chen Huiling reported: It took 122 days and the voyage was nearly 35,000 kilometers. The “Marine VI” ship of the Guangzhou Marine Geological Survey of the Ministry of Natural Resources completed the 8th Deep Sea Geology Voyage of the China Geological Survey and the 55th Scientific Expedition of the China Geological Survey, with a full range of scientific research results. It returned to Guangzhou on October 23.
The Ocean VI ship set sail from Guangzhou on May 30, 2019. It has carried out multiple methods of investigations such as multi-beam topography measurement, shallow strata profile measurement, marine gravity measurement, “Seahorse” ROV investigation, deep-sea shallow drilling sampling, deep-sea photography, in-situ acoustic thickness measurement of cobalt-rich crust, temperature and salt depth measurement, geological trawling and gravity piston sediment columnar sampling.
The 8th Deep Sea Geology Voyage and the 55th China Ocean Voyage Expedition were organized by the China Geological Survey and the China Ocean Mineral Resources Research and Development Association, and were specifically implemented by the Guangzhou Marine Geological Survey Bureau. The voyage has cooperated with 58 scientific expedition team members from Zhejiang University, Shanghai Jiaotong University, Donghai Station of the Institute of Acoustics of the Chinese Academy of Sciences, China Natural Resources Newspaper and other institutions to overcome many difficulties such as harsh sea conditions, lack of supplies, and equipment failures.
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, 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 sediments were obtained, which laid the foundation for the scientific research and evaluation of new resources in the deep-sea earth system.
The second is to continue to carry out the annual resource survey of my country’s cobalt-rich crust contract area and implement the Babaylan 1990 cloth drawThe obligation of the “Cobalt-rich crust Exploration Contract” signed by the China Ocean Association and the International Seabed Administration. The investigation results provide support for the resource evaluation of the cobalt-rich crust contract and the successful completion of the regional abandonment task 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 my country-Confucian friendship
In addition, during the berth of the Ponape Port of Micronesia on September 9, the Embassy of the Federal Embassy in Mission jointly held a reception to commemorate the 30th anniversary of the establishment of diplomatic relations between China and Mission on the “Ocean Six” ship, and invited the political leaders of the Michigan federal government and relevant China Cinema 1950 witch cloth drawRepresentatives of the investing institutions 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 newly-appointed marine scientific research survey ships in my country have referred to the basic design of “Ocean VI”. Since 2009, “Ocean VI” has been listed as the Babaylan 1990 cloth draw. It has been 55 voyages in the South China Sea, the Pacific Ocean and Antarctic Ocean for 10 consecutive years. The total sea trip time 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. It has accumulated scientific investigations and navigation support experience in the entire sea area, significantly improving my country’s marine geological scientific investigationslevel.

In recent years, many newly-listed marine scientific research survey ships in my country have referred to the basic design of “Ocean VI”. The ship adopts international advanced technical equipment such as electric propulsion systems, power positioning systems, full swing rudder paddles, and is equipped with a variety of advanced survey equipment. It has high integration and automation, good versatility, and can meet the requirements of comprehensive surveys of multiple disciplines and means. The ship is 105.66 meters long, 17.35 meters wide, 5.5 meters draft, 4335 total tonnage, full load displacement of 4650 tons, economic speed of 12 knots, maximum speed of 16 knots, self-sustaining force of 60 days, endurance of 15,000 nautical miles, Komiks 1960 witch cloth draw is entitled to 65 people.
