Abstract

Kondisi oseanografi di perairan Maluku dipengaruhi oleh variabilitas iklim ENSO salah satunya adalah kedalaman mixed layer. Menggunakan data satelit observasi dan data model untuk mengetahui kondisi angin, suhu permukaan laut dan kedalaman mixed layer tebal jangka waktu 10 tahun, penelitian ini bertujuan untuk mengetahui pengaruh ENSO terhadap ketebaln mixed layer di perairan Maluku. Dengan mengginakan data kedalaman mixed layer dari Marine Copernicus, kami menemukan bahwa saat periode El-Niño (2015/2016) pada wilayah upwelling mengalami penipisan sebesar 2 meter sedangkan pada wilayah yang tidak terjadi upwelling mengalami penebalan sebesar 1- 2 meter. Saat periode La-Niña (2010/2011) tidak mengalami upwelling sehingga perairan ini mengalami penipisan hingga 7 meter pada seluruh perairan Maluku. Fenomena ini sangat berkaitan dengan kondisi angin di perairan Maluku.Kata kunci: ENSO, Suhu Permukaan Laut, Angin, Kedalaman Mixed Layer dan Perairan Maluku Oceanographic conditions in Maluku Seas are influenced by ENSO climate variability, one of which is the mixed layer depth. Using satellite observation and model data to determine wind, sea surface temperature and mixed layer depth condition in a period 10 years, this study aims to determine the influence of ENSO on the mixed layer depth in Maluku Seas. Using mixed layer depth data from Marine Copernicus, we found that during the El-Niño (2015/2016) the upwelling area experienced a shallower 2 meters while in the area that did not occur upwelling experienced a deeper 1-2 meters. During the La-Niña  (2010/2011) there was no upwelling so that these seas experienced shallower up to 7 meters in Maluku Seas. This phenomenon is clearly related to wind conditions in the  Maluku Seas.Keywords: ENSO, Sea Surface Temperature, Mixed Layer Depth, Winds, and Maluku Seas
