Chinese research vessels Explore 1 and Explore 2 have discovered 66 ancient relics among the wreckage of three ships in the north area of the South China Sea, the Institute of Deep-sea Science and Engineering, Chinese Academy of Sciences recently revealed.
The newly discovered relics include porcelain fragments, redware pottery and bronze coins. The treasures were found on the seabed among three shipwrecks located 2,000 to 3,000 meters below the surface.
This depth marks a new deep sea milestone for China's underwater archaeology as the previous record for an underwater excavation by Chinese archeologists was 1,000 meters below the surface.
"This puts us on the same level as other countries that are advanced in the field of underwater archaeology. There are really not that many countries in the world that can carry out such deep sea archaeology," Cui Yong, head of the team that excavated the famous Song Dynasty (960-1279) Nanhai No.1 shipwreck in the South China Sea, told media.
Unmanned deep submersible technology was a significant advancement introduced to assist in the latest underwater investigation.
The submersible is capable of using sonar to locate objects as small as a grain of rice and can cover an area of around 100 square kilometers a day.
