The International Standard for Active Source Detection of Ocean Bottom Seismometer was jointly prepared by the SIO, the Institute of Geology and Geophysics, Chinese Academy of Sciences, the South China Sea Institute of Oceanography, Chinese Academy of Sciences, Guangzhou Marine Geological Survey and other units, and the project leader was Academician Li Jiabiao. By relying on the ocean bottom seismometer independently developed by China and fully studying the technical situation of similar products in the world, the technical requirements for active source detection of ocean bottom seismometer, such as terminology, instrument calibration, external design, OBS release and recovery, artificial seismic source, operation process, data acquisition and processing, were standardized, and the key technological achievements independently innovated, such as acoustic responder, release mechanism, acquisition mode and attitude seismometer, were transformed into international standards, which greatly improved the quality of data achievements of ocean bottom seismometer active source detection, and promoted the sound development of ocean bottom seismometer exploration.

  China put forward the proposal (NP) for this international standard in 2019, which was voted by 11 member states of the International Organization for Standardization Marine Technology Subcommittee (ISO/TC 8/SC 13) in March 2020, and was officially approved by ISO. After several rounds of technical modifications, it was officially released in May 2022. The implementation of this standard is beneficial for promoting the improvement of technical performance of ocean bottom seismometer and the unification of data formats in various countries, boosting the international cooperation of different countries in investigation, development and utilization of seabed resources, playing a crucial part in cooperation with countries along the Belt and Road in Southeast Asia, and enhancing the export and international influence of China’s independent marine equipment.

The Key Technology of Marine Laser Remote Sensing and Its Application is an innovative achievement in the field of ocean laser remote sensing, which is obtained by the research team of the SIO headed by Researcher Mao Zhihua, together with 13 advantageous units in China, after fives years of joint efforts, under the support of the national key research and development project “Research on the Mechanism and Model of Ocean Optical Remote Sensing Detection”. Focusing on the technical difficulties of the national marine environment three-dimensional profile remote sensing survey and the urgent need of developing China’s marine laser satellites, the achievement realized breakthrough in three key technologies: airborne blue green dual-wavelength ocean laser remote sensing technology, small angle measurement technology of ocean volume scattering function, and tunable field detection technology of shipborne ocean laser radar system; obtained five landmark achievements: shipborne marine laser remote sensing technology, airborne marine laser radar remote sensing technology, demonstration of indicators of spaceborne ocean laser radar systems, ocean laser radar radiation transfer model, and active passive ocean optical remote sensing fusion technology; gained three major innovations: the development and comprehensive testing of various shipborne ocean laser detection equipment of different systems, the demonstration of technical indicators for spaceborne ocean laser radar systems, and the ocean laser radiation transfer model based on measured water volume polarization scattering phase function. This has accumulated experience and reserved technology for the new system of ocean laser satellite detection in China in the future.

This achievement fills the gap of China in the seamless measurement of land and sea topography and the marine environment monitoring through algae, provides support for technical indicators of China's spaceborne marine laser radar system, promotes China's assurance capability of marine environment security information, and realizes the leap development of China’s marine optical remote sensing technology.
