Shenyang, October 7, Xinhua News Agency (reporter Wang Ying, Li Heng) The Autonomous underwater robot Exploration-4500, developed by the Shenyang Institute of Automation under the Chinese Academy of Sciences, has successfully completed a scientific expedition to the high-latitude sea-ice covered area in the Arctic during China's 12th arctic scientific expedition. Four scientists have returned with the research ship Xuelong 2.
The successful dive of the autonomous underwater vehicle in the high latitude area of the Arctic provides important data for China to continuously deepen the exploration and understanding of the multi-layer material and energy exchange and geological processes in the Arctic mid-ocean ridge, and will provide important scientific support for China's in-depth participation in the environmental protection of the Arctic.
Aimed at the characteristics of high intensity sea ice covering the arctic survey work area, innovative research team developed acoustic remote control and automatic ice recovery technology, combining the guidance of fast moving and recycle waters overcome the sea ice to recycle the challenge of underwater robot with narrow area, ensure the underwater robot in dense the areas covered by sea ice in the arctic northern waters for success, And all safely recovered.
In the application of scientific research, "Exploration 4500" has successfully acquired near-bottom high-resolution multi-beam, hydrological and magnetic data, providing an advanced exploration technology for the arctic deep-sea frontier scientific research, such as the topography and geomorphology of the ultra-slow expanding Yakke Ridge, magma and hydrothermal activity.
It is reported that "Exploration 4500" is a deep-sea equipment supported by the Strategic priority science and technology special project "Matter and energy exchange and its influence in the Tropical Western Pacific Ocean System" of The Chinese Academy of Sciences. In order to participate in the arctic scientific expedition, the research team upgraded and upgraded the "Exploration 4500" in technologies such as environmental adaptability, high-latitude navigation, seabed detection and fault emergency treatment, and carried out lake-sea verification work, comprehensively improving the reliability of the system.
The successful application of "Discovery 4500" in scientific research has fully verified its good adaptability to low temperature environment in the Arctic ice region, high latitude and high precision navigation performance, fault emergency treatment ability in dense ice region, and fine detection ability of mid-ocean ridge near the seabed.
