Heading towards the stars and the sea, intelligent remote sensing and other technologies reveal the mysterious mask of the deep sea

A person and a boat, floating on the boundless sea, seem to have a bit of loneliness and romance. This is also a vivid portrayal of the marine scientific research many years ago. Restricted by factors such as backward supporting equipment and lack of professional technology, marine reliability is often time-consuming and laborious, but little progress has been made. Since the reform and opening up, my country's scientific and technological construction has advanced by leaps and bounds, and research efforts in scientific research fields such as space observation and deep-sea exploration have continued to increase. Cutting-edge technology and intelligent equipment have also become "surprise weapons" for deep-sea exploration.

In recent years, some scientific research institutions have begun to use cutting-edge technology to carry out marine scientific research and deep-sea exploration activities. For example, the role of intelligent remote sensing in deep-sea exploration is increasingly prominent. Unlike land, the deep sea has complex geological structures and large temperature changes. When using deep-sea submarines and scientific research vessels to conduct deep-sea scientific research activities, if technologies such as intelligent remote sensing and satellite positioning are not used, the scientific research ships are likely to lose their way.

The comprehensive use of GPS, satellite navigation, intelligent remote sensing, air, space, ground and sea integration technology, etc., is reshaping the original pattern of ocean exploration from different aspects. The use of smart equipment is more like a torch, lighting up the dark corners of deep-sea scientific research. At the same time, the application of new generation information technologies such as big data, cloud computing, and the Internet of Things, coupled with "magic weapons" such as Internet of Things sensing equipment and underwater robots, have made deep-sea exploration even more powerful

Looking at the world, the Helmholtz Marine Research Center, which is mainly engaged in polar, ocean and climate research, has begun to try to use machine learning image analysis to find mineral manganese nodules hidden under the Pacific Ocean. They used machine learning algorithms to comprehensively analyze the images returned by underwater robots, analyze the shape of the seabed containing manganese nodules, and then calculate the probability of minerals hidden in unfamiliar sea areas. Doing so improves the efficiency of underwater exploration to a certain extent.

The monitoring and management of water environments such as domestic lakes and oceans are also inseparable from big data, remote sensing monitoring and other technologies. Recently, researchers from the Water Environment Remote Sensing Group of the Northeast Institute of Geography and Agricultural Ecology of the Chinese Academy of Sciences collected more than 2,000 water body samples and combined them with remote sensing data to construct a new remote sensing model for estimating water body transparency based on the ratio of red and blue bands. For the first time Achieve 30-meter resolution remote sensing inversion of lake water transparency across the country (using sensors/remote sensors to detect the radiation and reflection characteristics of electromagnetic waves of objects), which also starts from aAt a certain level, it has verified the application value of remote sensing and other technologies in geographical environment monitoring.

As a natural gene resource library, the deep sea undoubtedly contains huge potential for application and development, and is an important strategic resource for the country. After more than ten years of development, my country has achieved many results in deep-sea bioprospecting, basic research on deep-sea biology, standardized construction of deep-sea microbial resource libraries, and assessment and development of biological resource application potential. Next, accelerating the use of "black technology" means to explore the reserves and distribution of my country's deep sea natural resources, and making plans for the protection and utilization of marine resources will inject more powerful energy into the healthy development of my country's marine industry.

There is no end to progress. On the journey to climb the peak of science and technology, being lazy and slack will often lead to wasting all previous efforts. What is gratifying is that through unremitting efforts, our country has achieved the level of following and taking the lead in certain fields in deep-sea exploration technology. For example, the "Jiaolong" manned submersible can dive to a depth of more than 7,000 meters, which is very rare in the world.

Silence is like the sea. The voices and research of many scientists are making the mysterious territory of the deep sea no longer out of reach and unattainable. Every breakthrough and progress in cutting-edge technology demonstrates my country's confidence and determination in exploring maritime territory, maintaining maritime security, and exploring marine resource reserves. The year 2020 may be nothing in the long river of time. But in the field of marine scientific research, we look forward to more surprises!
