Long-term sea level trend from tidal data in Malaysia

A broad range of evidence shows that the climate system has warmed. One of it obvious effects due to global warming are sea level rise. Studies have been conducted to see the impact of global warming towards the changes in sea level. In this study, a total of 21 tide gauge stations along the Malaysian coastlines were used to analyse the rate and magnitude of sea level rise using robust fit regression. Tidal data used in this study is from year 1984 to 2013, which is about 30 years. The analysis shows that the total average sea level rate for Malaysian Seas including Peninsular Malaysia, Sabah and Sarawak is rising at 3.67 +/-0.15 mm/yr. While the total average magnitude of sea level rise is at 0.095 m. Conclusively, the sea level trend for all stations along the coasts of Malaysia shows an increasing pattern. This study offers valuable sea level information particularly related to environmental issue such as flood and global warming in Malaysia.
