Abstract

Sea surface temperature (SST) is one of the oceanographic factor in seawater. Its value depends on several factors. In indonesia, SST value depend on season and location. The aims of this study are to analyze the spatial and temporal variability of SST using 10-years (2007-2016) Aqua Modis satellite data. The result shows that the average of SST in Indonesia ranges from 27 – 31 °C depending on location. SST in equator area range from 30 – 31 °C and in nonequator area range from 27 – 30 °C. Monthly and seasonal variation of SST also show different value for each area in the indonesian region.

Highlights

Sea Surface Temperature (SST) is one of the oceanographic factor in seawater
The characteristics of SST variabilitity in Indonesia generally have largest seasonal cycle which occurs in Timor, Arafura, Banda, and South China Seas
A series of monthly and yearly SST data are derived from the Aqua MODIS level 3 Standard Map Image from NASA was collected from the period of 2007 – 2016 to study SST variability in the Indonesian region. the Aqua MODIS (Moderate Resolution Imaging Spectroradiometer) is designed for the accurate measurement of SST [4]

Summary

INTRODUCTION1

Indonesia is one of the tropical country that has territory stretches from 6° 08’ north latitude to 11° 15’ south latitude and from 94° 45’ to 141° 05’ east longitude. Its located between the Pacific and the Indian Ocean, and bridges two continents, Asia and Australia [1]. The consequences of the complexity of topography and connectivity between the Pacific and the Indian Ocean in this region can affect the sea surface temperature. The Sea Surface Temperature (SST) play important role in atmospheric state both locally and globally [2]. The characteristics of SST variabilitity in Indonesia generally have largest seasonal cycle which occurs in Timor, Arafura, Banda, and South China Seas. The highest SST variability occurs along and offshores Java and Sumatra coast. The variability of SST influences by monsoon or season [2]. The main purpose is to analyze the average temperature of SST as well as its monthly and seasonal variations
