Jinyang.com News Reporter Zhao Yanhua Komiks Correspondent Chen Huiling reported: It took 122 days and a voyage of nearly 35,000 kilometers. The “Ocean VI” ship of the Guangzhou Marine Geological Survey of the Ministry of Natural Resources completed the 8th voyage of the China Geological Survey of the China Geological Survey and the 55th voyage of the China Geological Survey, with full loads of scientific research results and 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 joined forces with 58 scientific expedition team members from Zhejiang University, Shanghai Jiaotong University, Cinema Institute of Acoustics, China Natural Resources Newspaper and other institutions to overcome numerous difficulties such as harsh sea conditions, lack of supply, and equipment failure.
Deep-sea exploration has made three important progress
According to reports, this time, 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’s cobalt-rich crust contract area.
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 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, the intelligent segmentation splicing of underwater video images was implemented in Cinema, providing basic data for the research on the 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 successfully applied to multiple carrier platforms such as ROV and mobile drilling rigs, providing powerful investigation methods for the fine exploration 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 conducted 55 deep-sea geological, ocean and polar scientific investigation tasks in the South China Sea, the Pacific and Antarctic waters for 10 consecutive years. The cumulative 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 orbiting the earth. It has accumulated experience in scientific investigation and navigation support in the entire sea area, and has significantly improved the level of marine geological scientific investigation in my country.

Ship Background: The “Ocean VI” scientific research ship
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-entered marine scientific research ships in my country have referred to the basic design of “Ocean VI”. The ship adopts international advanced technical equipment such as electric propulsion system, power positioningBabaylan system, full slewing rudder oars, and is equipped with a variety of advanced survey equipment. It has high integration and automation, good versatility, and can meet the comprehensive survey of multidisciplinary and means. href=”https://funnybookish.com/”>Cinema requirements. The length of the ship is 105.66 meters, 17.35 meters wide, 5.5 meters draft, 4335 total tonnes, 4650 tons of full load displacement, 12 knots of economic speed, 16 knots of maximum speed, 60 days of self-sustaining power, 15,000 nautical miles of range, and 65 people. Since its induction in 2009, the Ocean VI ship has conducted a survey on natural gas hydrate resources in the South China Sea area of our country. In addition to the national marine survey projects such as oil and gas resource survey, marine regional geological survey, as well as key equipment installation tests and deep-sea exploration shared scientific expedition missions, as well as deep-sea geological surveys, ocean scientific surveys and polar scientific surveys, a total of 55 voyages, total of 2,137 days of sea trip, safely sailing 290,000 nautical miles (about 535,000 kilometers), the voyage is equivalent to 13 and a half circles orbiting the earth. Investigation sea area packageIncluding the South China Sea, the Pacific Ocean and the Antarctic waters, after 10 years of baptism, the “Marine VI” ship has achieved fruitful results. It has explored and accumulated experience in marine geological scientific investigation and navigation support in the entire sea area of my country, and has significantly improved the level of marine geological scientific investigation in my country.
The “Ocean VI” ship has strong comprehensive investigation capabilities and complete scientific research methods. It is known as the all-round king of comprehensive scientific investigations of deep-sea oceans in my country. It is equipped with advanced equipment for multidisciplinary surveys such as geology, geophysics, and marine environment, such as multi-disciplinary surveys, such as multi-channel earthquakes, multi-beams, shallow formation profiles, gravity and magnetism, near-bottom observation operating systems such as ROV (“Seahorse” and “Sea Lion”), AUV, and subsea cameras, deep-sea shallow drilling, ultra-long gravity columns, box-type sampling, multi-tube sampling, geological trawling nets, biological trawling nets, temperature-salt depth (CTD), and high-precision operation support systems such as dynamic positioning and underwater positioning, which plays an important demonstration role in the design and construction of my country’s subsequent scientific research ships. Since its inclusion, the Ocean VI ship has completed a total of nearly 110,000 kilometers of shipboard geophysical (multibeam, shallow formation profile, gravity and magnetic force, etc.) measurement lines, more than 2,000 kilometers of submarine camera measurement lines, and nearly 100 kilometers of AUV acoustic measurements; 23 ROV dives, 409 deep-sea shallow drilling stations, 294 gravity column samples, 230 box samples, and 26 geological trawls (more than 11 tons of multimetallic nodule samples were obtained); more than 450 environmental biological survey stations (CTD, biological trawls, anchor systems, etc.), and accumulated rich basic marine geological geological geophysical data.
