(Petrik Siano Okta Prima Lesmana. 26050119130125. Pengaruh El Nino
Southern Oscillation Periode El Nino 2015 – 2016 dan La Nina 2010 – 2011
terhadap Intensitas Upwelling di Perairan Utara Papua. Anindya Wirasatriya dan
Heryoso Setiyono).
Perairan Utara Papua merupakan perairan yang memiliki kondisi oseanografi
kompleks karena berada di Indo-Pacific Warm Pool (IPWP). Letak perairan yang
berada di belahan bumi selatan menyebabkan terjadinya upwelling pada musim
barat (DJF). Meskipun demikian, kondisi interannual seperti El Nino Southern
Oscillation (ENSO) dapat memengaruhi intensitas upwelling yang berada di
perairan tersebut. Penelitian mengenai pengaruh ENSO terhadap upwelling di
Perairan Utara Papua telah dilakukan sebelumnya. Namun, penelitian tersebut
hanya menggunakan data Sea Surface Temperature (SST) dan klorofil-a sebagai
parameter utama indikator upwelling. Oleh sebab itu, penelitian ini memiliki tujuan
untuk mendapatkan perbandingan intensitas upwelling yang terjadi di Perairan
Utara Papua pada fase netral terhadap fase ENSO dengan menambahkan parameter
Ekman Mass Transport (EMT) sebagai indikator utama upwelling. Data yang
digunakan dalam penelitian ini meluputi data SST, klorofil-a, angin, EMT, dan
curah hujan yang berasal dari GHRSST, OC-CCI, ASCAT, dan GSMaP.
Pengolahan data menggunakan metode komposit bulanan dengan analisis spasiotemporal berdasarkan hasil anomali. Hasil analisis menunjukkan bahwa El Nino
2015 – 2016 menyebabkan peningkatan intensitas upwelling sebesar 1.82 – 4.00
m/s2
sementara La Nina 2010 – 2011 menyebabkan pelemahan intensitas upwelling
sebesar 4.95 – 6.56 m/s2
di Perairan Utara Papua. Berdasarkan analisis korelasi dan
regresi, didapatkan kesimpulan bahwa EMT hanya berpengaruh besar terhadap
anomali upwelling di bagian tenggara perairan sedangkan bagian barat laut perairan
lebih dipengaruhi oleh kondisi IPWP.

ABSTRACT
(Petrik Siano Okta Prima Lesmana. 26050119130125. The Effect of El
Nino Southern Oscillation El Nino Period 2015 – 2016 and La Nina 2010 – 2011
on Upwelling Intensity in North Papua Waters. Anindya Wirasatriya and
Heryoso Setiyono).
North Papua waters are waters that have complex oceanographic conditions
because they are in the Indo-Pacific Warm Pool (IPWP). The location of the waters
in the southern hemisphere causes upwelling in the west monsoon (DJF).
Nonetheless, interannual conditions such as the El Nino Southern Oscillation
(ENSO) can affect the upwelling intensity in these waters. Research on the effect of
ENSO on upwelling in North Papua Waters has been done before. However, this
study only used data on Sea Surface Temperature (SST) and chlorophyll-a as the
main indicator parameters for upwelling. Therefore, this study aims to obtain a
comparison of the upwelling intensity that occurs in the North Papua Waters in the
neutral phase to the ENSO phase by adding the Ekman Mass Transport (EMT)
parameter as the main indicator of upwelling. The data used in this study include
SST, chlorophyll-a, wind, EMT, and rainfall data from GHRSST, OC-CCI, ASCAT,
and GSMaP. Data processing uses the monthly composite method with
spatiotemporal analysis based on anomaly results. The results of the analysis show
that El Nino 2015 – 2016 caused an increase in upwelling intensity of 1.82 – 4.00
m/s2 while La Nina 2010 – 2011 caused a weakening of upwelling intensity of 4.95
– 6.56 m/s2
in the North Papua Waters. Based on correlation and regression
analysis, it can be concluded that EMT only has a major effect on upwelling
anomalies in the southeastern waters while the northwestern waters are more
influenced by IPWP conditions.
