xinhua news agency, tokyo, september 22 (xinhua) japanese media reported on the 22nd, citing the japan agency for marine-earth science and technology, that japan's "earth" deep-sea exploration ship drilled 980 meters down at a depth of 6,897.5 meters in the japan trench, and the detection depth from the sea surface reached 7,877.5 meters, breaking the deep-sea scientific drilling record held by the ship.
japan's "daily news" website reported on the 22nd that the researchers on the "earth" connected a 40-meter-long drill pipe, continued to dig after reaching the seabed, and reached 7877.5 meters below the sea surface on the 21st.
according to the website of the japan agency for marine-earth science and technology, the "earth" went to the waters of miyagi prefecture to conduct exploration in order to investigate the latest situation of the submarine fault in the northeastern waters after the 2011 "3.11" earthquake.
according to data, in april 2012, the chikyu conducted a drilling survey of the fault that caused the major earthquake off the coast of oshika peninsula in miyagi prefecture, setting a record for deep-sea scientific drilling with a total drill pipe length of 7,752.3 meters. (end)
