66 cultural relic specimens!2022 The South China Sea In -depth Joint Scientific Examination achieved significant results

Recently, the reporter learned from the Institute of Deep Sea of ​​the Chinese Academy of Sciences that a joint voyage consisting of "Explore No. 1" and "Explore No. 2" scientific test ship achieved major results in the northern part of the South China Sea. A total of 66 cultural relic specimens were found.

According to scientific researchers, this scientific examination was found in the bottom of the 2000-3000 meter depth and found 1 underwater cultural relics and three hulls and multiple monochrome glaze tanks. In terms of archeology depth, my country's underwater archeology depth exceeded 2018 for the first time 2018 1000 meters year. It is understood that the routes connecting the southern coast and the Xisha Islands across the continental frame, the mainland slope and the South Ocean basin. The "manned submersible, and combined with the equipment such as cable -free self -lames.

Chen Chuanxu, an associate researcher at the Institute of Deep Sea Science and Engineering of the Chinese Academy of Sciences: This deep -sea archeological discovery benefits from the introduction of unmanned deep -dive technology, and the combination of manned and unmanned deep diving. We first use acoustic drags for a large -scale search. We can search for about 100 square kilometers a day. Then use the AUV (cable -free autonomous submarine) to continue the area where the suspected point is located continuously. If the shipwreck or suspicious cultural relics are found in the photo, the manned deep dives are arranged for underwater verification confirmation and the extraction of cultural relics.

Such high -tech collaborative operations involve more than a dozen domestic navigation units, expand the ability of maritime scientific research to explorate and work, and greatly improve efficiency. Researchers have carried out image data extraction, three -dimensional laser scanning, environment and hull sediments and wood sample collection, and extract 66 cultural relics such as pottery, porcelain, purple sand, copper coins, and ship plates.

Deng Qijiang, deputy director of the Institute of Water and Archeology of the National Cultural Relics Bureau: This survey has a certain understanding of the dynamic changes in the distribution laws of deep -seawater cultural relics, especially the distribution of shipwrecks, and the storage status. The complete workflow of the survey has accumulated experience for the search and discovery of deep -seawater underwater cultural relics in the future, and laid a solid foundation for the in -depth development of deep -sea archeology in the future.

The follow -up team will conduct further in -depth research on the age and source of the hull in a comprehensive application environment, geology, archeology and other discipline analysis methods.
