A study of sea surface temperature (SST) changes in Merang and Rompin coastal area from in-situ data and satellite imagery

Abstract

The study of sea surface temperature (SST) has been done widely across the globe and close-related to different events of natural phenomena in our atmosphere. It is also applicable in understanding the relation between SST and the recent issue of climate change. This study focuses on the SST determination of Merang and Rompin coastal area. At the same time, the objective is to determine the relationship between in-situ and sate11ite-derived SST data. By using the application of Moderate Resolution Imaging Spectroradiometer (MODIS), the data were obtained in the form of 3-day, 8-day composite data and annual SST data. The in-situ sampling was completed on 20th to 22nd June 20 I I at Merang coastal area and 30th June to I st July 20 I I at Rompin coastal area, followed by second sampling on 20th to 22nd October 2011 for IRompin coastal area. The average of SST at Merang and Rompin coastal area were 29.53°C and 29.85°C respectively. From the results and projection of obtained data, the value of R2 for both Merang and Rompin coastal area were 0.104 and 0.436; while the value of RMS error were 1.2379 and 0.6353 respectively. By the end of this study, the pattern of previous 5 years SST were observed and related to the previous occurred phenomena. It is observable that the inclining of SST due contributes to certain events such as El-Nino. Further study is crucial in having a better understanding of the relationship between SST and the ocean phenomenal occurrences.
