Lautan Indonesia merupakan wilayah perairan yang merupakan penghubung antara Lautan Pasifik dan Lautan Hindia, serta Laut China Selatan. Variasi permukaan laut yang relatif tinggi di bagian barat Lautan Pasifik mempengaruhi variasi laut di perairan Indonesia. Salah satu penyebab variasi permukaan laut di kawasan ini adalah pengaruh fenomena El Niño Southern Oscillation. Penelitian ini bertujuan melakukan perhitungan korelasi antara El Niño Southern Oscillation dan variasi permukaan laut di perairan Indonesia. Hitungan korelasi menggunakan  Multivariate El Niño Southern Oscillation  memberikan hasil adanya korelasi kuat negatif antara El Niño Southern Oscillation dan variasi permukaan laut sebesar -0,8.
