China heard the sound from the Mariana crevice

Chinese scientists made a big breakthrough after successfully conducting the first acoustic experiment from the deepest ocean in the world.

China Ocean News said researchers from the Northwest Polytechnic University in Shaanxi Province performed a near experiment. This abyss is located in the Pacific Ocean, at the southern end of the Mariana gap.

The test involves sending down and retrieving a 10km audio transducer equipped with sensors that can record at a distance of 9.3km.

"Chinese scientists, for the first time, heard the sound from the deepest part of the ocean," the newspaper wrote.

Lu Liangang, a researcher at Qingdao Oceanographic Institute, participated in the mission, telling the newspaper that this is the second time a sound experiment was performed in the Mariana trench.

Challenger Valley is located about 320km southwest of Guam, the deepest point known on Earth. Few scientific groups have been there since a US submarine made its first discovery in 1960.

The purpose of China's sound experiment, which takes about a year to prepare, is to learn how sound is transmitted in deep waters. Because there is no light below, many organisms have to rely on sound to communicate.

According to Collin Koh Swee Lean, a researcher at the Maritime Security Program at the S. Rajaratnam School of International Studies, Nanyang Technological University in Singapore, marine sound research could have military applications.

"Civilian research projects can be used for military purposes, as in this case, understanding the sound characteristics in the trench can promote deep-sea sound research, helping scientists. learns to refine technology and help strengthen anti-submarine or underwater capabilities , Koh said.

Chinese scientists also left six sound sensors in the Mariana valley to collect information on sea noise for a year and will take them back in November 2018.

China has performed many exploratory missions, both manned and unmanned, to the deepest point of the Mariana gulf about 2,400km long and about 70km wide. In 2016, China became the third country, after the US and Japan, to have an unmanned submarine that could descend more than 10,000 meters. Chinese Haidou ships can dive as deep as 11,000m.

Deep-sea scientific exploration is one of the key projects in the 5-year plan, to 2020 by Beijing.
