Luhuitou, located at the south end of Sanya, is a "mid mountain peninsula" formed by waves hitting sand for hundreds of millions of years. Here, a love myth of Li youth chasing deer women has been handed down for thousands of years. When the mother ship of scientific research carried the "striver" and other equipment into the South China Sea, the Indian Ocean and the Pacific Ocean, the story of China's conquest of the far-reaching sea was also recorded and praised one by one. From theory to core technology, from model to scientific research weapon, from shallow sea to 10000 meter abyss, the young Institute of deep sea science and engineering of the Chinese Academy of Sciences (hereinafter referred to as the Deep Sea Institute of the Chinese Academy of Sciences), carrying the mission of a maritime power, has been exploring and breaking through. In the past, a small fishing village has emerged as a deep-sea science and technology highland. Forge a self-reliance tool for a big country in science and technology The Deep Sea Institute of the Chinese Academy of Sciences, which was established in 2011 and officially established in 2016, undertakes the important task of national deep-sea scientific research and research and development of deep-sea key technologies and equipment. Since its establishment, the Institute has adhered to the road of scientific and technological self-reliance and self-improvement. "In just five years, we have successively completed the transformation of two scientific research ships and the localization of operation equipment." Yang Ning, deputy director of the Deep Sea Institute of the Chinese Academy of Sciences, said. In 2014, the Chinese Academy of Sciences took the lead in marching into the sea bucket abyss greater than 6500 meters in China, and successfully developed a series of unmanned abyss scientific research equipment such as "Tianya". That year, China had the ability to enter and explore the 10000 meter deep sea for the first time. In 2017, the 4500 meter manned submersible "deep sea warrior" completed its sea trial in the South China Sea. Chief designer Hu Zhen commented that with low operation and maintenance cost, it can basically cover the exploitable depth of sea resources all over the world. In 2020 and 2021, the Deep Sea Institute of the Chinese Academy of Sciences took the lead in organizing scientific research institutions to the Mariana Trench, the "fourth pole of the earth", and completed the sea test and scientific research application tasks of the "striver" all sea deep manned submersible respectively. 21 10000 meter dives witnessed the challenge of Chinese scientific researchers to the limit of the deep sea. Cultivate fighting spirit and train practical team When the researchers raise the five-star red flag on the blue ocean on TV, when the model of "striver" appears in the national science and Technology Museum, and when the scientific research ship returns to Hong Kong, it welcomes the crowd... Behind this is the hard work of the deep-sea scientific researchers, which is rarely known. "Deep sea scientific research is a work with great technical risks and high work intensity. It often has to complete the seemingly 'impossible task' under the condition of seasickness and physical weakness." Yang Ning said: "the motto we stick to is' better take risks than deserters'. In every scientific research site, everyone can come together." It is this fighting spirit that opened the era of 10000 meters of abyss scientific research in China. The more setbacks, the more courage, and the more victories, thanks to the fact that the Deep Sea Institute of the Chinese Academy of Sciences took the lead in breaking the "four only" in talent training: evaluating engineering and technical talents based on performance, practical ability and cooperative spirit; Evaluate scientific research talents based on performance and paper level; With the most complex sea conditions and the most difficult field work, the scientific researchers have trained and created a group of backbone talents with an average age of only 35. Realize catch-up and leap forward and continue to explore and innovate Once the engine of the scientific research ship roars, the mysterious deep sea is no longer "dream and distance". On Luhuitou Peninsula, which extends from Sanya City to the sea, the Deep Sea Institute of the Chinese Academy of Sciences has gradually become not only the gathering place of national deep-sea major equipment, but also the gathering place of international high-level deep-sea scientific research talents, realizing the leap of "from entry to detection to development" and "from following to local leading" in the field of deep-sea scientific research. Wang Pinxian, an internationally renowned Chinese "academician of deep diving", believes that one of the biggest advances in Earth Science in the past half century is the discovery of the deep-sea world. "All difficulties will not stop us from yearning for the deep sea." Yang Ning said that the Deep Sea Institute of the Chinese Academy of Sciences has begun to plan a new round of innovation and change. "We are breaking the boundaries of systems, departments and disciplines, cooperating with more than 100 domestic units to build an innovation system of 'small core and large network', actively exploring the establishment of a new national scientific research system, and making more contributions to human understanding, protection and development of the ocean."
