Abstract

The GEO2TECDI – SONG project in cooperation with Thailand and EU about marine surveying concluded that speed of sea level rise (SLR) in Thailand Gulf fluctuated between 3,2-5,8 mm/year which was higher than the speed of mean SLR in the World. This paper that initially calculates and analyses the trend of fluctuation in sea level in long time reaches a conclusion that the speed of SLR in which was measured at Vietnam stations fluctuated between 1,2-4,2 mm/year based on calculation from mean sea level data. This data is believed to be suitable for data surveying from satellite altimetry in GEO2TECDI – SONG project. The result of identification SLR that was measured at Vietnam stations was based initially on short-different surveyed water level. However, this paper contributes to general conclusion about the speed of SLR in Coastal Vietnam that has been high and increased for last 10 years.
