Abstract：This paper chooses several IGS tracking stations which distributed in coastal and inland regions of globe，uses the basic theory of the effect of ocean loading on station displacement to design a variety of programs to process the monitoring data.The results show：1）The effect of ocean tide loading on the station elevation was cm level；2）The effect of ocean tide loading on troposphere zenith delay estimation was mm level 3)There exists weak linear relationship between the troposphere effect of ocean loading and the influence of elevation.
