Red Dawn 2 Number ” The comprehensive scientific research vessel successfully completed a 10,000-meter-deep-sea scientific expedition in the Mariana Trench. It also successfully recovered oceanographic instruments and equipment that had been continuously operating in the Mariana Trench for nearly a year. Additionally, the vessel tested China’s domestically developed wave gliders and high-definition deep-water cameras—among other marine scientific research equipment.

Professor Tian Jiwei, chief scientist of the expedition and a professor at the Functional Laboratory for Ocean Dynamic Processes and Climate Change at the National Marine Laboratory, introduced that this expedition involved the retrieval of data from the Mariana Trench Oceanographic Comprehensive Observation Network established by the National Marine Laboratory. The observation network includes: 5 Integrated deep-sea scientific observation buoy, 9 Set up ocean-bottom seismometers, 1 Equip with devices such as the deep-sea seabed boundary layer measurement system.

In addition, researchers are working on... 4000 Mizu deep-sea Argo floats, autonomous underwater vehicles (AUVs) with remote control and no cable, wave gliders, and real-time deep-water systems. / Self-contained HD video cameras, 10,000-meter deep-water sampling devices, and deep-sea gravity sediment samplers capable of operating at depths of up to 10,000 meters, among others. 8 Systematic sea trials were conducted using marine instruments and equipment independently developed by China.

Tian Jiwei introduced that researchers have also conducted comprehensive oceanographic surveys covering the entire water depth along a large cross-section of the Mariana Trench, as well as large-volume water sampling and deep-sea seabed sediment sampling.

Wang Zaiyi, Executive Deputy Director of the National Ocean Laboratory, said that this voyage is part of the National Ocean Laboratory’s efforts. “ 10,000-Meter Deep-Sea Action Plan ” a part of it. Through the implementation of this plan, the Ocean National Laboratory will be established. “ Deep diving, deep drilling, deep sensing ” the ability.

Wu Lixin, Director of the National Laboratory for Ocean Science and Technology and an academician of the Chinese Academy of Sciences, introduced that the National Laboratory for Ocean Science and Technology has already formulated plans for deep-sea exploration. “ Three-step approach ” Strategy: The first step is to deploy a batch of deep-sea intelligent buoys independently developed by China in key marine areas, and to establish a real-time, three-dimensional, multidisciplinary integrated observation system, including in the Mariana Trench. The second step involves focusing on the dynamic mechanisms of plate tectonics and the Eurasian continental plate. “ Diving black hole ” Major cutting-edge scientific issues such as formation mechanisms, deep carbon cycling, and life processes in extreme environments—leveraging... “ Jiaolong ” Manned submersibles and other equipment to the western Pacific. - A comprehensive survey of key marine areas in the Indian Ocean will be conducted, with the aim of achieving original innovations in the aforementioned cutting-edge scientific issues. As a third step, over the next three to five years, the National Marine Laboratory will promote the initiation and construction of China’s ocean drilling vessel, using it as a platform to foster synergistic development between deep-sea and deep-earth sciences and to seek major breakthroughs in Earth science. △ (
