Abstract

Sea level rise is a real impact of global climate change and can have severe consequences for regional and local ocean hydrodynamics. This study analyzes the trend of sea level rise in Tambu Bay using data from the Geospatial Information Agency (BIG). The existence of sea level data for Tambu Bay obtained from measurements is compared with data from the Geospatial Information Agency. Hourly observation data for 1 (one) month provides an RMSE value of 0.18 cm. After the least squares inter-calibration procedure and seasonal trend decomposition based on SARIMA and trendline, it is known that the rate of sea level rise in Indonesia is +1.4 mm/year in the period 1985-2024. This positive linear trend indicates that the sea level in Indonesia will continue to increase, where y is the sea level anomaly, and x is time.
