General; --- Part 2. oceanographic observations; --- Part 3. Marine meteorological observations; --- Part 4. Marine Chemistry Elements investigation; --- Part 5. Ocean Sound, light elements investigation; --- Part 6. Marine Biological Survey; --- Part 7. Marine survey data exchange; --- Part 8. Marine Geological Geophysical Survey; --- Part 9. Marine Ecological Survey Guidelines; --- Part 10. seabed topography survey; --- Part 11. Marine Engineering Geological Survey. Wherein Section 9, Section 10 and Section 11 corresponds to GB/T 12763-1991 is a new section. This is Part 5 GB/T 12763, and instead of GB/T 12763.5-1991 "oceanographic survey - Marine sound, light modulation elements check". This part of GB/T 12763 Part 1 and GB/T 12763 Part 7 supporting the use. This section compared with the GB/T 12763.5-1991, the main changes are as follows. --- Part of the optical elements borrowed from NASA (NASA) 2002 edition of "Ocean Optics specification for satellite ocean water Color sensor test (OceanOpticsProtocolsforSateliteOceanColourSensorValidation, 2002) ", And combined with the specific situation of China II water, we made a comprehensive revision. In addition to keeping the existing sea illumination observation, the remaining weight The new compilation. It adds radiance observations in the optical elements. To collectively irradiance "apparent volume optical observation" and radiance measurements. Based on these two Being a observables derived from sea water is important radiance, remote sensing reflectance, irradiance reflectance, diffuse attenuation coefficient in the data processing Yang optical parameters. The original specification "sea visible light transmittance observation" was changed to "the amount of inherent optical observation." Observational elements in the optical portion of the measurement requirements, technical indicators, measuring methods, equipment and data processing have heavy Major changes in the respective sections are detailed provisions and requirements. --- Combined with acoustic elements of the current development of underwater acoustic observation instruments, technical requirements and methods of measurement parameters and data compilation for Modified. This section in Appendix A, Appendix B, Appendix C, Appendix D and Appendix E is an informative annex. This part by the State Oceanic Administration. This part is administered by the National Oceanic Standards and Metrology Center. This part of the State responsible for drafting the First Institute of Oceanography, National Satellite Oceanic Application Center, the National Oceanic third marine research The National Ocean Technology Center participated in the drafting. The main drafters of this section. Dingyong Yao, Tangjun Wu, Songqing Jun, Yang Yanming, Wang Yanfeng, Ma Yi, Wang Xiang Nan, Julien students. This part of the standard replaces the previous version of the case. --- GB/T 12763.5-1991. Oceanographic survey Part 5.
