Abstract

<p>Sea Surface Temperatures (SSTs) is one of the most important oceanographic parameter that could affect the marine life, especially coastal ecosystem. SSTs data varies in hourly, daily, seasonal, annual, inter-annual, and even in longer time scales. This condition makes any studies using instantaneous measurement could turn into misleading report due to the lack of time series SSTs data. Thus, the aim of this study is to understand the seasonal and intra-seasonal SSTs dynamics in Pari Island using continuous measurement from temperature logger. This study found that the double peaks of SSTs in May and November are correspond to the period of transitional monsoon. Conversely, the two minimum SSTs in February and August were correspond to the peak of northwest monsoon and southeast monsoon respectively. In addition to seasonal pattern, the slightly dominant intra-seasonal variability of SSTs was found in the period of 57 and 86 days. Those predominant signals suggested represent the Madden-Julian Oscillation phenomena.</p>

Highlights

Pari Island – Thousand Islands Jakarta is one Elevated sea surface temperatures (SSTs) suggested have a significant role as the main cause of coral bleaching (Brown and Suharsono, 1990; GBRMPA, 2017; Wouthuyzen et al, 2015; Wouthuyzen et al, 2018)
Several coral reef area were reported have been damaged by giant El Niño 2016 including Great Barrier Reef Marine Protected Area (GBRMPA, 2017) and coastal area of Indonesian Seas (Wouthuyzen et al, 2018)
SST varies due to larger scale climate phenomena such as Madden-Julian Oscillation (MJO) (Madden and Julian, 1994; Napitu et al, 2015; Zhang, 2008), Indian Ocean Dipole (IOD) (Saji et al, 1999), and El

Summary

Introduction

Pari Island – Thousand Islands Jakarta is one Elevated sea surface temperatures (SSTs) suggested have a significant role as the main cause of coral bleaching (Brown and Suharsono, 1990; GBRMPA, 2017; Wouthuyzen et al, 2015; Wouthuyzen et al, 2018). Of the coastal areas suspected to have an indirect impact of increased SSTs during the giant El Niño 2016 This kind of environmental damage could have been mitigated if we understand the variability of SSTs well. It is suggested that SSTs in Pari Island mainly driven by monsoonal winds in the annual scale (Halkides et al, 2011; Kida and Richards, 2009; Qu et al, 2005). Local processes such as tidal mixing and air-sea heat fluxes suggested could affect SST variability (Gordon, 2005). SST varies due to larger scale climate phenomena such as Madden-Julian Oscillation (MJO) (Madden and Julian, 1994; Napitu et al, 2015; Zhang, 2008), Indian Ocean Dipole (IOD) (Saji et al, 1999), and El
