After 163 days , a range of 20,000 sea miles . November 6 , Chinese research vessel "Ocean VI" of 6000 meters equipped with unmanned untethered submersible " Qianlong One" arrived at the mouth of the Pearl River in Guangzhou Marine Geological wharf , which marks China Ocean 29th voyage of scientific investigation and the China geological Survey Bureau of investigation 's first leg win over the ocean .

5 leg carry out resource , environmental, biological, and other surveys

May 28 this year , "Ocean VI" set sail from Guangzhou , worked in the country for polymetallic nodules in the eastern Pacific area, the Clarion - Crippa Dayton fracture zone (CC area ) , rich country in the western Pacific Plucking mine cobalt crusts in the Pacific basin seamounts and other four areas to carry out resource , environmental, biological and other investigations, including Guangzhou Marine geological Survey , the National Oceanic two , one , Qingdao Institute of marine Geology, 13 research institutes , etc. 95 expedition members to participate in the voyage of scientific investigation . This is the "Ocean VI" Executive Ocean expedition staff rotation most of the time .

The second and third leg Chief Scientist , Guangzhou Marine Geological Survey , said senior engineer Liu Fanglan , China Ocean 29 expedition voyage into three flight segments , in addition to the first and second leg added between China Geological Survey Bureau special investigation of rare earth resources in the ocean leg . In a different segment , "Ocean VI" Plucking seamounts were completed mining resources and the local area detailed exploration , CC District detailed exploration for polymetallic nodules , new resources surveys and on 6000 m unmanned untethered submersible " Qianlong One " application test. At the same time , the synchronization in the investigation area to carry out environmental, biological surveys , especially in the CC area means a wide range of more comprehensive environmental survey . In addition, China Geological Survey Bureau carried out a segment of new rare earth resources in deep-sea exploration work . Expedition team used various means , the system launched a new resource potential in the Pacific and rare earth exploration to further verify its distribution .

July 19, 2013 , the International Seabed Authority approved the " China Ocean Mineral Resources Research and Development Association," proposed mining exploration for cobalt-rich crusts 3000 km2 . In this expedition voyage , the expedition team for the first time in our country in the western Pacific crusts exploration prospects means more detailed investigation carried out for the next project crusts resource evaluation and exploration deployment study provides detailed information , and the successful implementation long cycle environmental observation .

Meanwhile, the " Ocean VI" continues in our area to carry out environmental surveys for polymetallic nodules in the contract to fulfill China Ocean Association and the International Seabed Authority signed the " exploration contracts ," and for the first time at the International Seabed Authority, the proposed environment, especially area of concern for multi- tools, multi-disciplinary environmental research . The CC area to carry out a wide range of environmental surveys , carried out water chemistry , microbiology , benthos , plankton, chlorophyll, mainly to environmental baseline studies , multidisciplinary environmental research , and further complements the Contract Area environmental baseline data .

" Qianlong One" applied successfully completed sea trials

The expedition staff voyage to China has independently developed the 6000 m deep towed acoustic systems and " Qianlong One" pilot applications were carried out and applied sea trial . Which acoustic detection system for the first time deep tow successfully applied crusts mining resources survey , synchronous access to the bathymetric , sidescan , shallow section , three acoustic probe data . " Qianlong One" in the eastern Pacific polymetallic nodule mining 5000 Duo Mihai our test domain , seven successful dive underwater for nearly 30 hours to obtain a number of bathymetric sidescan , shallow stratigraphic section , hydrology , etc. data . Both sets of equipment successfully tested deepwater exploration and application of deep-sea technology development to become an important landmark.

In this expedition during the "Ocean VI" also successfully launched the " Pacific - Guangzhou," marine science classroom activities . Via satellite connection to Guangzhou nearly a hundred students were taught real knowledge of marine science , ocean knowledge in the popularization made ​​a new attempt.

Reporters learned that the "Ocean VI" boat is designed by our own , self- build the first one with the international advanced level of gas hydrate comprehensive survey ship , is currently the world's a more complete configuration of comprehensive geological Earth physical survey ship .
