ã€China Instrument Network Instrument Research and Development】 The 10,000-meter submarine seismograph independently developed by the Institute of Geology and Geophysics of the Chinese Academy of Sciences has been successfully applied in the depths of the world's deepest challenger in the Mariana Trench. China has become the world’s first successful access to 10,000 meters. Marine seismic seismic profiles in countries.
The reporter recently learned from the Chinese Academy of Sciences that the "Exploration No. 1" scientific expedition ship launched 60 types of submarine seismographs of the three types in the above sea area and recovered 56 sets. On February 28th, it completed two 10,000-meter-level artificial seismic sections with maximum recovery. The depths are 10027 meters and 10026 meters respectively, and the actual working length of the section is 669 kilometers.
These data are extremely precious. According to experts, submarine seismographs are an important equipment for marine geoscience exploration. By recording seafloor seismic fluctuation signals, seismic waves are imaged on submarine strata to provide a basis for understanding the internal structure of the sea floor.
The Institute of Geology and Geophysics began its "Ninth Five-Year Plan" period. After nearly 20 years of hard work, it successfully developed a 10,000-meter submarine seismograph. China has also become the second country after Japan with the ability to independently develop submarine seismographs of 10,000 meters.
On January 15 this year, the Chinese Academy of Sciences Abyssal Expedition team sailed from Sanya on the “Exploration No. 1†scientific expedition vessel and sailed to Mariana Trench and Yapu Trench to perform abyss scientific investigation and equipment testing mission. At present, the scientific expedition team is still in the challenger's abyssal waters of the Mariana Trench.
