Variasi Parameter Oseanografi di Utara Laut Arafura pada Tahun Super La Nina 2010 dan El Nino 2015
Variation of Some Oceanographic Parameter in The Northern Arafura Sea During Super La Nina 2010 And El Nino 2015
Abstract
Tujuan penelitian ini adalah mengetahui variasi parameter oseanografi di Utara Laut Arafura selama kejadian ekstrim super La Nina 2010 dan El Nino 2015. Data yang digunakan bersumber dari multi-dataset model CMEMS Copernicus, yang telah divalidasi dengan data observasi satelit. Hasil penelitian menunjukkan suhu permukaan dan tinggi muka laut ditemukan lebih rendah selama kejadian super El Nino 2015. Sebaliknya, salinitas permukaan dan ketebalan lapisan tercampur mengalami peningkatan selama kejadian La Nina 2010. Arus lapisan dalam yang mengarah ke timur menyebar sepanjang slope pada periode Monsun Tenggara mengalami penguatan selama kejadian El Nino.
