SEA LEVEL TREND AND VARIABILITY IN THE SOUTH CHINA SEA

In this study, long-term tide gauge observations and multi-mission satellite altimetry data were used to investigate the spatial distribution of the long-period tidal contribution in Chinese seas and analyze the relative long-period tidal contribution rate into four regions. The result indicate that the long-period tidal constituent cannot be neglected in the establishment of the LNLW datum to improve tidal datum precision.
