The Variability of Sea Surface Height Anomaly in the Seas Along the Northern and Southern Coast of Java Island

Abstract

The dynamics coastal in Indonesia is fluctuative. It is caused by geographical location of Indonesia. This study aims to analyze the sea surface height anomalies in the southern and northern waters of the Java Island. This assessment was based on data of sea surface height anomalies from the Jason 2 satellite in 2010-2016 obtained from Copernicus. Data processing use MATLAB R2014a to compare the sea surface height in the northern and southern waters of Java Island. The sea surface height anomaly in the northern waters of Java Island ranged from 0 - 0, 15 meters and in the southern ranged from -0, 1 - 0.15 meters. It is because southern waters of Java Island directly adjacent to the Indian Ocean. The highest sea surface height anomaly in the both of area occurs in May and minimum anomaly in September, influencing by monsoon. Generally, sea surface height anomaly in southern was higher than northern waters of Java Island.
