Abstract With the extensive use of pressure tide gauge,the data accuracy is more and more concerned.Based on the pressure tide level calculation principle,this paper analyses and compares tidal data between the pressure and float type on the marine observation platform.The error relationship and its causes of the both tidal data are obtained.Combined with the calculation and calibration to pressure tidal data of seawater temperature,salinity and the location of gravity acceleration,the purpose of data calibration is finally achieved.The data errors of pressure tide gauge are effectively reduced,which provide a technical basis for the accuracy of maritime temporary tide data.
