Jinyang.com News Reporter Babaylan 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 Bureau 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 Bureau, full 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 stratigraphic profile measurement, ocean gravity measurement, “Haima” ROV investigation, deep-sea shallow drilling sampling, Komiks deep-sea photography, in-situ acoustic thickness measurement of cobalt-rich crust, temperature and salt depth measurement, geological trawling and columnar sampling of gravity piston sediments, etc.
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 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.
Deep sea exploration has made three important progress<a 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 system 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, and provide support for the resource evaluation of the cobalt-rich crust contract area and the successful completion of the regional abandonment task stipulated in the contract.
The third is that technological innovation-driven deep-sea exploration has made important progress. 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 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’s Close Friendship
In addition, he berthed on September 9th<a During the Port of Ponape, the Federal Embassy of Micronesia, we cooperated with the 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 Federal Government of Mission and relevant Chinese-funded institutions to visit the Marine VI 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 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 investigations in the South China Sea, the Pacific and the Antarctic waters for 10 consecutive years. The cumulative time of sea trip reached 2,137 days, safely sailing 290,000 nautical miles (about 535,000 kilometers), with a range of 13 and a half circles orbiting the earth, and has accumulated science in the entire sea area.The experience of academic inspection and navigation support has significantly improved the level of scientific inspection of marine geology in my country.

The Guangzhou Marine Geological Survey Bureau of the Ministry of Natural Resources, the “Marine 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”. 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 Cinema is 105.66 meters long, 17.35 meters wide, 5.5 meters draft, 4335 total ton, full load displacement of 4650 tons, economic speed of 12 knots, maximum speed of 16 knots, self-sustaining power of 60 days, endurance of 15,000 nautical miles, and a capacity of 65 people. Since its induction in 2009, the “Ocean VI” ship has conducted national marine survey projects such as natural gas hydrate resource survey, oil and gas resource survey, and marine area geological survey in my country’s South China Sea. In addition to 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 in various scientific expedition tasks, with a total of 213 voyages.7 days, safely sailed 290,000 nautical miles (about 535,000 kilometers), and the voyage was equivalent to 13 and a half circles around the earth. The surveyed sea areas include the South China Sea, the Pacific Ocean and the Antarctic waters. After 10 years of baptism of wind and waves, the “Ocean VI” ship has achieved fruitful results, and has explored and accumulated experience in marine geological scientific investigation and navigation support in my country’s entire sea area, significantly improving the level of marine geological scientific investigation in my country.
