China enhances underwater drilling to 5000m

China has successfully increased its deep-sea drilling capability to 5,000 meters using the vessel "Mengxiang," setting a national record after analyzing basalt samples in the South China Sea basin. This achievement marks an important step toward China’s entry into the ranks of advanced nations in deep ocean drilling operations, making it the third country, after the United States and Japan, to obtain hard rock samples from the ocean floor using drilling ships. The effort involved operating two remotely operated vehicles for over 358 hours at a depth of 4,000 meters, along with the application of advanced processing and analysis techniques for the samples. This supports major scientific research on the expansion of the South China Sea and the development of the marine environment, affirming China's growing technical capabilities in ocean exploration.
