General; --- Part 2. oceanographic observations; --- Part 3. Marine meteorological observations; --- Part 4. Seawater chemical 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. Part 9. Marine Ecological Survey Guide, Part 10. A survey of the seabed topography and the Section 11. Marine engineering geological survey correspond In GB/T 12763-1991 is a new section. This section GB/T 12763 "oceanographic survey" Part 8, instead of the GB/T 13909-1992 "sea oceanographic survey Yang geological and geophysical investigations. " This part of GB/T 12763 Part 1, Part 7 and Part 10 supporting the use. This section compared with the GB/T 13909-1992 main changes are as follows. GB/T 13909-1992 versions of articles, chapters, articles, paragraphs, Part edition according to GB/T 1.1 "Standardisation Guideline 1. The structure and preparation of standard requirements "to chapter, section, subsection structure. Excerpts of Table 1 compared with GB/T 13909-1992 version has four changes. --- Deleting "open sea", "offshore" parts and its contents, are far from the sea near the same requirements; --- Deleting 1.200 × 104 scale survey content, part of the project to increase 1.10 × 104 scale investigation and 1.5 × 104 content; --- By deleting "in a corresponding scale map sheet on distance (mm)" to specify the accuracy of navigation positioning, to use DGPS positioning; --- Marine gravity measurements, marine geomagnetic measurement standard of measurement accuracy are greatly improved, the accuracy of which marine geomagnetic measurements Increase by a big margin, the original 1.100 × 104 and measurement accuracy 1.50 × 104 scale was increased from 12nT and 8nT 4nT; original scale of 1.20 × 104 measurement accuracy by the 4nT increased to 2nT. Chapter 5 seabed topography survey due to a significant change in the survey methodology, and therefore independence to become the new standard, GB/T of the first 1,012,763 Part. Submarine topography survey, this chapter to refer to the new standard. Excerpts Chapter 6 seabed sediment survey content with multiple variations. --- 6.1.3.2b) column sampler length requirements specified in the original deep sea of not less than 50cm, not less than 100cm are replaced by shallow Not less than 150cm, updated sampling weight of 300kg ~ 600kg; --- 6.3.2.3 sediment grain size analysis instrument to change the original use of Coulter laser particle size analyzer; --- 6.3.3.2 sediment grain size classification and naming updating deep-sea sediments triangle classification; --- 6.3.3.3 Sorting Table 4 of the original seven grade level, etc., etc. merge five; --- 6.5 sediments physical and mechanical properties test new custom penetration strength test and cobalt-rich crusts and rock physical and mechanical properties testing; --- 6.7 sediments chemical assay, change 6.7.8 Determination of organic carbon, total nitrogen determination 6.7.10, 6.7.11 carbonate measured by Square Elemental analysis method are analyzed. Chapter 7 of the title of "sub-bottom structure detected" instead of the original version of the title of "sub-bottom structure and surface sediments acoustic detection" 7.1 And 7.2 respectively "towed shallow stratigraphic profiling" and "boat-load detection shallow stratigraphic section" instead of the original version of "stratigraphic profiling" and "sea The end of the multi-frequency probe "and delete the contents of calculation and abundance of polymetallic nodules coverage; Chapter 9, the "gravity anomaly" to replace the original word "free-air gravity anomaly," word; 9.4.1.1 marine gravity measurements of the original note Acceptance levels recorded in the standard d paragraph "a continuous online measurement missing records less than 10% of the survey line length, total length of survey line missing less than 20%, not Eligible survey line is less than 10% of the total survey line, "was changed to" a lack of continuous recording survey line survey line length is less than 5%, less than the cumulative lack of measurement 10% of the long line, measuring line failure less than 5% of the total survey line. " Original Article 6 of Chapter 10, "marine sediment paleomagnetic measurements," notes 6.9 sediment paleomagnetic measurements.

It is assumed that the ocean newborn oceanic crust continuously generated from the mid-ocean ridge, and to promote two Side of the oceanic crust on both sides to expand, due to the high temperature of the newborn oceanic heat and gradually cooled, thus forming a crust with age and heat flow diminishes to Low trend. According to the theoretical model, it can be measured with the theoretical value of heat flow heat flow comparison, calculate the age of oceanic crust. 3.5 Acoustic receiver voltage gain of the variation with time. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 12763.8-2007_English be delivered?Answer: Upon your order, we will start to translate GB/T 12763.8-2007_English as soon as possible, and keep you informed of the progress.
