Foreword

GB/T 14914 "Ocean Observation Specification" is divided into six parts. --- Part 1. General; --- Part 2. Seaside observation; --- Part 3. Buoy subsurface observation; --- Part 4. Shore-based radar observations; --- Part 5. Satellite remote sensing observations; --- Part 6. Data processing and quality control. This part is the second part of GB/T 14914. This part is drafted in accordance with the rules given in GB/T 1.1-2009. This part replaces GB/T 14914-2006 "Seaside Observation Specification". The main technical changes in this section compared with GB/T 14914-2006 are as follows. --- Revised the normative reference document (see Chapter 2, Chapter 2 of the.2006 edition); --- Removed the term "sea state" (see 3.1 of.2006 edition); --- Added the term "day boundary" (see 3.6); --- Increased the requirements for the observation and recording of the longitude and latitude of the ocean observatory (point), the area requirements of the meteorological observation field, and the installation requirements of the observation equipment. Lightning protection measures for ocean observing stations (points), site migration comparison observation requirements, operational operation comparison observation requirements, update of observation instruments Marine equipment observatories (points) should document activities that have an impact on the observed data (see 4.1); --- Revised observing procedures and supplementary testing regulations (see 4.2, 4.4 of.2006 edition); --- Amend the observations of sea ice observations and marine disasters and anomalies during severe glacial periods to observations of marine disasters and anomalies (See 4.3, 4.3 and 4.5 of the.2006 edition); --- Revised the relevant regulations for inspection and school hours (see 4.5, 4.7 of.2006 edition); --- Increased quality control of the seashore observation process (see 4.6); --- Revised the observation project in time (see Chapter 5,.2006 edition 4.2); --- Revised the leveling requirements of the benchmark (see 6.1.6.2, 5.1.6.2 of the.2006 edition); --- Revised the requirements for the newly installed well water gauge (see 6.1.7.4.1,.2006 edition 5.1.7.4.1); --- Increased manual observation, data recording, and the organization and recording of abnormal data (see 6.2.2, 6.2.3, 6.2.4); --- Added corrections to data records (see 6.2.7.3.2); --- Removed the calculation formula for calculating the height from the seabed to the tidal reference plane (see 6.1.4 of.2006 edition); --- Removed the wave height, periodic eigenvalues and their code numbers (see 6.2.4.2 of the.2006 edition); --- Increased manual direction of wave direction, wave height, wave period (see 7.2.3.1, 7.2.4.2); --- Increased the formula for calculating the water depth [see equation (5)]; --- Increased manual observation of surface seawater temperature (see 8.2.2); --- Increased data logging requirements (see 8.2.3); --- Deleted the comparison of on-site observation instruments, the collation of observation data and the calculation formula of salinity [see.2006 edition of 8.1.6, formula (4)]; --- Increased manual observation of surface seawater salinity (see 9.2.2); --- Increased data logging requirements (see 9.2.3); --- Revised the requirements for observational elements (see 10.1.1, version 9.1.1 of the.2006 edition); --- Removed the requirement that the observation point should be selected from a height of 2m~6m from the sea surface (see 9.1.2 of.2006 edition); --- Revised the initial (final) ice date determination (see 11.1.6,.2006 edition of 10.1.7); --- Revised the requirements for the lack of measurement of ice observations (see 11.2.1.4, 10.2.2.3 of the.2006 edition); --- Increased the observation of the shore optical wavemeter, manual visual observation of the drift direction and speed of the ice floe (see 11.2.7.1, 11.2.7.2); --- Increased the content of the ice map (see 11.2.15.2); --- Increased sea ice observations during severe glacial periods (see 11.2.17); --- Revised the requirements for the accuracy of relative humidity (see 12.1.2.2); --- Increased manual observations (see 12.2.2); --- Increased the organization and recording of abnormal data (see 12.2.4); --- Prepare observations of precipitation as a separate chapter (see Chapter 13); --- Revised the accuracy requirements for observations of wind speed (see 14.1.2.1); --- Removed the setting of the observation field (11.1.3 of the.2006 edition); --- Increased methods for manual measurement, manual visual measurement of wind speed, wind direction and observation data (see 14.2.2, 14.2.3, 14.3); --- Increased the collation of artifacts and observations (see 15.2.2, 15.3); --- Removed the processing of observation data (see Chapter 15 of the.2006 edition); --- Increased seashore observation data transmission (see Chapter 17); --- Increased on-site comparison method of observation equipment for ocean observing stations (points) (see Appendix B); --- Revised the cover format of the seashore observation record book (see Table A.1, Table A.5, Appendix A of the.2006 edition); --- Revised the setting of the tide well (see Appendix C, Appendix B of the.2006 edition); --- Removed the processing and quality control of seashore observation data (see Appendix F of the.2006 edition).
