Introduction

In recent years, with the development of research on sea level rise and climate change, the standardization, standardization and precision of ocean observations have not been standardized. Make higher demands. On the one hand, changes in the zero point of tide surveys, changes in the tide survey environment, changes in tide survey locations, tide survey methods and instrument updates directly or Indirectly caused the inconsistency of the tidal data starting surface, and it is impossible to form a sea level data series with a unified reference; on the other hand, the observation background Or changes in observational instruments will also affect the consistency of the data series of sea surface temperature, salinity and meteorology. These problems have seriously affected Reliability of research results of sea level and climate change analysis. Carrying out the benchmark tide level verification work, the purpose is to investigate and collect ocean observations Basic information, analyze and approve the influence of unnatural factors in the observation records, and form an accurate and reliable data sequence of observation elements. Therefore, the benchmark Tide level verification is not only the verification of tide zero point, elevation system, observation background, observation instruments and tide level observation data, etc., but also verification and tide level observation data. The observation process and observation data of closely related temperature and salt, waves and weather and other elements. Benchmark tide level verification work on sea level rise Research and response to climate change, marine pre-warning, and disaster prevention and mitigation work are of great significance. In order to effectively guide the benchmark tide level verification work, The industry standard "Technical Guidelines for Benchmark Tide Level Verification" was formulated. This standard can also be used as a reference for water conservancy, meteorological and other departments to carry out related work. Technical Guide for Benchmark Tide Level Approval

1 Scope

This standard specifies the work content of the reference tide level verification, the verification requirements of the leveling measurement, the collection content and requirements of the verification information, and give The report preparation format is presented. This standard applies to the verification and management of the reference tide level of marine stations (measurement points), and the tide level verification work of other hydrological stations or tide gauge stations can be referred to use.

3 Terms and definitions

The following terms and definitions apply to this document. 3.1 Mean sea level The average value of the tide level recorded by continuous observation over a long period of time. Note. The average sea level of a station usually refers to the average value obtained from the hourly tide level observations of this station over 19 years. 3.2 1956 Yellow Sea elevation datum YelowSeaverticaldatum1956 The average sea level calculated from the tidal observation data of Qingdao Dagang Tide Gauge Station from 1950 to 1956 is also called the 1956 Yellow Sea average sea level. The origin of the level of the People's Republic of China is 72.289m higher than the 1956 Yellow Sea elevation datum. 3.3 1985 national elevation datum national vertical datum 1985 The average sea level calculated from the tide observation data from 1952 to 1979 at Dagang Tide Gauge Station in Qingdao. Origin of the People's Republic of China 72.260m higher than the 1985 national elevation datum. 3.4 Tidegaugezero Tide observation records the starting surface of sea level height.
