Sea Level Variability Around Belitung Using Satellite Altimetry

Abstract

The Sea around Belitung Island is an oceanic pathway for the South China Sea and the Java Sea which has some characteristics. This paper addresses to determine sea level variation around Belitung Island using satellite altimetry observation. Several parameters applied to determine sea level anomaly. Based on the altimeter measurements for a period of 24 years (1993 – 2016), the rates of sea level rise are 4.3 mm year of B1, 4.6 mm year for B2 and 4.5 mm year for B3. The southern sea of Belitung island has a higher sea level rate than northern area, due to its influenced by El Niño Southern Oscillation. The correlation indices between Multivariate El Niño Southern Oscillation and detrended Sea Level Anomaly are -0.41, -0.56 and -0.54 for points of B1, B2 and B3, respectively.
