Deep-sea methane in-situ detection technology breakthrough

Dr. Zhang Xin of the Institute of Oceanography, Chinese Academy of Sciences as the first accomplisher has successfully developed a deep-sea methane in-situ detection system based on deep-sea ROV (Remotely Operated Vehicle) cable control robot in cooperation with the United States MBARI (Monterey Bay Aquarium Research Institute). The relevant research results have been Recently published in the "Geophysical Research Letters" (Geophysical Research Letters), and the first time by Nature2 and Science3 were reported and commented.

Using this technology, researchers for the first time obtained true in-situ concentrations of methane in deep-sea sediments, which are 10 to 20 times higher than the results of traditional sampling tests, thereby demonstrating that methane exists not only in natural gas hydrates but also in a large number in the deep sea. Sediment.
