Preface

Since its establishment in 1990, the Pan Ocean Remote Sensing Conference

(PORSEC) has rapidly gained global status as one of the most prestigious

Remote Sensing Conference in the world, with a scope covering all world

oceans. PORSEC is an organization dedicated to helping developing nations

stimulate their science programs with focus on the applications of remote

sensing technology in Ocean Sciences. PORSEC has provided over a decade of

effort with scientists from over thirty countries participating in conferences

once every two years.

The Indonesian National University of Udayana, together with National

Institute of Aeronautics and Space (LAPAN), are privileged to host PORSEC

2014, the Twelfth Biennial Conference with the theme “Ocean Remote Sensing

for Sustainable Resources” in Denpasar – Bali, Indonesia during November 4th-

7th, 2014.

The conference reviewed and discussed the state of ocean remote sensing and

will help scientists and students involved in ocean-atmosphere studies using

remote sensing techniques to benefit from interactions with the experts

participating from all over the globe. The conference also provide an

opportunity to showcase the research work carried out using remote sensing

techniques from various satellite missions and the applications of ocean

remote sensing for societal benefits.

The successful completion of the PORSEC 2014 Proceedings is the result of the

cooperation, confidence, and endurance of many people. All contributions are

greatly appreciated. It is impossible to overestimate the importance of their

efforts in helping us meet deadlines, their insights in editing, and their donation

of time.

ABSTRACT

The impact of Indian Ocean Dipole Mode (IODM) for the sea surface temperature (SST)variability in the Southern of Java and Lesser Sunda has been investigated. The Aqua MODISsatellite data has been used to investigating the SST distribution both spatially and temporally.The Dipole Mode Index (DMI) was calculated from 2003 until 2011 and found that 2010 has anindication as an IOD (Indian Ocean Dipole) year. It was coincide with the spatial change ofSST distribution in the Southern of Java and Lesser Sunda. The temporal change has beeninvestigating by wavelet transform, and found that the high spectrum indicated in 2010. It wasclearly found that in 2010 the SST variability in the southern part of Java Island and the LesserSunda has a strong relationship with the IODM. Those relationship was confirmed through thespatial, temporal and wavelet analysis methods.

1. INTRODUCTION

El-Nino Southern Oscillation (ENSO)andthe Indian Ocean Dipole Mode (IODM)are the largest earth climate phenomenon thathas a connection with the sea surfacetemperature (SST) anomaly. Severalinvestigation regarding to the influence ofENSO in the Indonesia seas has beenconducted, such as: the influence of ENSOfor the chlorophyll-a variability in thesouthern of Java (Susanto and Marra, 2005),the influence of ENSO for the upwelling inJava and Sumatra Sea (Susanto et al., 2001),and the influence of ENSO for the SST in theIndonesian Seas (Nicholl, 1983).Furthermore, some researches has been doneregarding to the IODM phenomenon, suchas: the dipole mode in the tropical area of theIndian Ocean (Saji et al., 1999), the structureof SST variability and surface wind in the

Indian Ocean during the IODM (Saji,Yamagata, 2003), the influence of IODM forthe rainfall in Indonesia (Hermawan, 2007),and the influence of IODM for the SST andsalinity in the Western of Sumatra(Holliludin, 2009).

The IODM has an impact for the rainfallvariability in some countries, such as Africaand Asia (Hu, Nita, 1996; Behera et al.,2006; Harou et al., 2006). The SSTvariability in the southern of Java and thewestern of Sumatra is one of the key factorsfor the IODM phenomenon, which is alsooccurred simultaneously with the changingof Indonesia season (Qu et al., 2005). Theperiod of IODM is more than a year(interannual) (Saji et al., 1999 and 2003; Raoet al., 2002) that could be influencing theclimate in Indonesia.

The SST in Indonesia Seas is the mostimportant point to determine the regional and

global climate. This is due to the complexsea bottom topography of the Indonesianseas, and also connecting the Pacific and theIndian Ocean (Qu et al., 2005).From thenumerical model and the field observationshows that a little change of SST inIndonesia could give a high change on therainfall in the Indo-pacific (Miller et al.,1992; McBride et al., 2003; Ashok et al.,2001; Neale, Slingo, 2003). The SSTvariability in Indonesia seas is also importantfor the ecology point of view, since theIndonesia Sea has a rich of the oceanbiodiversity. Therefore the investigation ofSST variability and its characteristicsbecome a substantial work. In this study, weused the satellite data to make aninvestigation of SST variability and itscharacteristics in the southern of Java and thelesser Sunda.

Remote sensing technology had beenwidely used to observe the ocean resources.The Moderate Resolution ImagingSpectroradiometer (MODIS) is one of thesatellite imaging that can be used easily tomake a periodic SST observation.Furthermore, the temporal analysis of SSTdata is done using wavelet transform, andhence the period and the time of thephenomenon can be analyzed.

1.1. Dipole Mode Index (DMI)

IODM signature are originally occurs inthe Indian Ocean. It could be due to anincreasing of SST in the western IndianOcean (50 W - 70 W and 10 S - 10 N), andsimultaneously decreasing of the SST in theeastern part of Indian Ocean (90 W – 110 Wand 10 S - Equator) (Saji et al., 1999). TheIODM is recognized by determining theDipole Mode Index (DMI), which is thedifference of SST anomaly between thewestern part and eastern part of Indian Ocean(Saji et al., 1999). Saji, et al. (1999)mentioned that the positive DMI (above 0.7)is the indication of the positive IODMphenomenon, whereas the negative of theDMI (below -0.7) is indicating the negativeIODM phenomenon. The more positive the

IODM, the higher SST in the western IndianOcean will be. This makes the convectionincrease around the western part of theIndian Ocean. However, the eastern part ofIndian Ocean will experience drought(including some areas in Indonesia). Theopposite phenomenon will occur during thenegative IODM.

1.2. Wavelet Transform

The wavelet transform is useful to analyzetime series data that contain non-stationarypower at many different frequencies(Foufoula-Georgiou and Kumar, 1995;Daubechies, 1990). Torrence, and Compo(1997) proposed a Morlet Wavelet that usedas the mother wavelet (Equation 1).

Ψ η = π / e ω ηe η / (1)Where is the non-dimensional frequencyand was taken to be 6 in this study to satisfythe admissibility condition (Farge, 1992).This is known as the scaled wavelet, which isdefined by:

Ψ′ − = /

Ψ′ − (2)

Where s is the dilation parameter used tochange the scale, and n is the translationalparameters used as time shifting. The s-1/2 isa normalization factor to maintain the totalenergy of the scaled wavelet constant.

The continuous wavelet transform (CWT)of a discrete sequence xn is a convolution ofxn with the scaled wavelet functions andtranslated from Ψ0() (Torrence and Compo,1997):

= ′Ψ∗ ′ −− 1′= 0 (3)

It is possible to calculate the wavelettransform using equation (3), but it would besimpler and easier if it done in Fourier space.Hence, by using the convolution theorem, thewavelet transform is the inverse of Fouriertransform of the product.

= Ψ∗− 1= 0 (4)

where the angular frequence is defined by:

= ∶ ≤− ∶ > (5)

Hence, the value of power spectum wavelet| | can be found from the waveletequation aboved.

2. Data and Method

The data used in this research is SSTderived from the Aqua MODIS satellite data.This data can be downloaded from NASAwebsite (http://modis.gsfc.nasa.gov/) as alevel 3 satellite data. The eight years monthlydata from 2004 until 2011 were used for theSST analysis.

SST Aqua MODIS satellite data in thesouthern part of Java and Lesser Sunda areaveraged spatially. The average value of SSTin the western Indian Ocean and the easternIndian Ocean also calculated to determinethe DMI that will be used for IODManalysis.

IODM is an interannual phenomenon(Saji et al., 1999 and 2003, Rao et al., 2002,etc.), while the period of SST in Indonesia isless than one year. Therefore the monthlySST data from Aqua MODIS is then filtered.This should be done to remove the seasonalchanges of each variable in order to obtain amore significant relationship between SSTand IODM.

After the seasonal effects of the SST hadbeen removed, the wavelet transform wereapplied (Equation 1-5). The power spectrumfor each variable then used to determine therelationship between IODM period and SSTvariability in the study area.

3. RESULT AND DISCUSSION3.1 Seasonal Characteristic ofSSTin the

Indonesia Seas

Seasonal characteristic of SST from 2003-2011 during rainy and dry season are shown

in the figure 1 and figure 2. Thecharacteristic of SST during rainy seasonwere determined by the averaged SST inDecember-January-February (DJF) period.While the June-July-August (JJA) data wereused to find the SST characteristic in dryseason. The SST in Indonesia during therainy season are shows warmer rather thandry season. There is also a significantdifference along the southern of Java Islanduntil Arafuru and Banda Sea, which makesthe SST becomes colder in dry season. Itcould be caused by the upwelling processdue to the monsoon (Wyrtki, 1961 and Qu,2005). However, warmer SST during therainy season is caused by the downwellingprocess.

Figure 1. SST Characteristics during rainy season(December-January-February [DJF])

Beside the difference of SST condition,the SST anomaly is occurred during the dryseasons in 2007, 2008 and 2010 along thesouthern of Java Island until Banda Sea(Figure 1). It shows that the SST wasdecreasing. However, the increasing of SSTwas occurred during rainy season at 2005,2009, and 2010 (Figure 2).

The power spectrum (PS) of DMIwith95% confidence level (bold countur line) arefounded at midle of 2009 until 2011.

However the SST variabilitythat shown by the power spectrum for 2003to 2006 is not coinciding with the DMIpower spectrum. It might be caused by theannual phenomenon of the Pacific Ocean(El-nino southern oscillation-ENSO). Besideof that, the variability of SST has the similarpattern with the DMI in 2010. SST in thesouthern part of Java Island and LesserSunda has the same periodicity with the DMIas shown in the GWS graph.

3.4 Wavelet Transform

The power spectrum (PS) of DMIwith95% confidence level (bold countur line) arefounded at midle of 2009 until 2011. Theperiod isaround 1 until 2 year (Figure 6a).The IODM is clearly occurred in 2010 withthe period of 2 years. However, thevariability of SST shown that the minimumtemperature is higher than normal conditionin the same year (Figure 3). The SST in thestudy area is spatially increasein 2009 andthe highest is occurred in 2010 (Figure 1 g-h). And the global wavelet spectrum (GWS)shown that the IODM wereoccurredperiodically with time period around 1 until5 years globally (Figure 6b).

Figure 7 shows the power spectrum ofSST in the southern part of Java Island and

Lesser Sunda. The period of SST variabilitywith 95% confidence level are founded at2003 to 2006 with time period of 1.5 year.Meanwhile, the time period in 2009 to 2011is 1 to 4 years. However the SST variabilitythat shown by the power spectrum for 2003to 2006 is not coinciding with the DMIpower spectrum. It might be caused by theannual phenomenon of the Pacific Ocean(El-nino southern oscillation-ENSO). Besideof that, the variability of SST has the similarpattern with the DMI in 2010. SST in thesouthern part of Java Island and LesserSunda has the same periodicity with the DMIas shown in the GWS graph.

Figure 7. Wavelet transform in southern part of JavaIsland and Lesser Sunda, a) Power Spectrum ofSST, b) Global Wavelet Spectrum (GWS) for SST

In order to determine the relationshipbetween SST variability and IODM in thesouthern part of Java Island and LesserSunda, the correlation coefficient betweenthe power spectrum of SST and DMI hadbeen calculated (Figure 8). The dot line inthe figure 8 refers to the 95% confidencelevel. Hence, the correlation coefficientabove the confidence level concluded as asignificant correlation. There is a positivecorrelation above the 95% confidence level,which is show a significant correlationbetween DMI and SST in the southern partof Java Island and Lesser Sunda. The

significant positive correlations occurred inthe 1.5 to 1.7 years, 2.2 to 2.8 years, and 4.7to 5 years’ time period. The result states thatSST in the southern of Java Island andLesser Sunda got a lot of impact from theIODM during those periods. While a strongnegative correlation may indicate that theannual variability of SST is caused by otherphenomenon.

4. CONCLUSION

The relationship between SST variabilityand the IODM in the southern part of JavaIsland and Lesser Sunda can be confirmed byusing the Aqua Modis Satellite data. It isclearly shown in 2010 that SST in thoseregions has a strong relationship with IODMphenomenon. This relationship is wellconfirmed by spatial, temporal and even bythe wavelet method.

For further study, the numericalsimulation will be useful to find an impactfor the ecology and climate condition inIndonesia, weather by the assimilation ofsatellite data or the in situ data.
