Abstract
Sea level variability is one of fundamental parameters for scientific development such as modeling the Earths climate. In addition, this parameter also plays crucial rules in mitigating socio-economic hazards due to sea level changes, especially in coastal areas. Mitigating the sea level hazards in an archipelagic country like Indonesia becomes more essential, since the country is geographically constructed by various bathymetric depths with different type of seas. One of attempts to study the sea level variability is to take benefit from satellite altimetry data. The TOPEX+JASON altimetry missions have observed sea level during more than 25 years, and hence the rate of sea level variability can thoroughly be studied. In this research, regional-scale variations in sea level over the Indonesian sea will be examined.
