Perairan Barat Aceh merupakan perairan yang dikelilingi oleh Samudera Hindia, Selat Malaka dan pantai utaranya berbatasan dengan Laut Andaman. Perairan dapat dipengaruhi oleh beberapa faktor hidrologi perairan seperti pasang surut, suhu, salinitas, pH, arus dan kecerahan. Tujuan dilakukannya penelitian ini adalah untuk menganalisis korelasi Sea Surface Salinity (SSS), Sea Surface Temperature (SST) dan Klorofil-a di Perairan Barat Aceh pada bulan Februari tahun 2021. Metode yang digunakan pada penelitian ini adalah metode analisis korelasi Pearson dengan menggunakan data yang bersumber dari Hybrid Coordinate Ocean Model (HYCOM) dan Copernicus Marine Environment Monitoring Service (CMEMS).Hasil dari penelitian ini adalah korelasi Sea Surface Salinity (SSS) dan Klorofil-a di seluruh domain di dapatkan korelasi r = -0.08 yang dikategorikan negatif tidak memiliki korelasi. Sedangkan korelasi di bagian garis pantai di mendapatkan korelasi r = 0.52 yang dikategorikan dalam korelasi positif sedang. Korelasi Sea Surface Temperature (SST) dan Klorofil-a di seluruh domain di dapatkan korelasi r = -0.34 dikategorikan korelasi negatif rendah. Sedangkan korelasi di garis pantai di dapatkan hasil korelasi r = 0.002 yang dikategorikan dalam negatif tidak memiliki korelasi. Korelasi Sea Surface Temperature (SST) dan Sea Surface Salinity (SSS) di seluruh domain di dapatkan korelasi r = 0.40 yang dikategorikan korelasi positif sedang. Sedangkan korelasi di bagian lepas pantai di dapatkan hasil korelasi r = -0.14 dikategorikan positif tidak memiliki korelasi. Berdasarkan hubungan antara tiga variabel tersebut dapat dimodelkan menggunakan model regresi linier, regresi polinomial ordo 2 dan pulinomial ordo 3. Hasil model menunjukkan bahwa koefisien determinasi yang paling tinggi itu adalah regresi polinomial 3 dengan koefisien determinasi antara SSS dan klorofil-a sebesar R2 = 0.15, variabel SST dan klorofil-a sebesar R2 = 0,11 dan variabel SST dan SSS sebesar R2 = 0,24.

Aceh's western waters are waters bounded by the Indian Ocean, the Malacca Strait and its northern coast are bordered by the Andaman Sea. Waters can be influenced by several water hydrological factors such as tides, temperature, salinity, pH, currents and brightness. The purpose of conducting this study was to analyze the correlations of Sea Surface Salinity (SSS), Sea Surface Temperature (SST) and Chlorophyll-a in the West Aceh Waters in February 2021. The method used in this research is the Pearson correlation analysis method using data sourced from the Hybrid Coordinate Ocean Model (HYCOM) and the Copernicus Marine Environment Monitoring Service (CMEMS). The results of this study are the correlation of Sea Surface Salinity (SSS) and Chlorophyll-a in all domains, a correlation of r = -0.08 is not contra-negative. have a correlation. While the correlation in the offshore section is obtained a correlation of r = 0.52 which is combined in a moderate positive correlation. Correlation of Sea Surface Temperature (SST) and Chlorophyll-a in all domains obtained a correlation of r = -0.34 low negative correlation. While the correlation on the coastline, the results of the correlation r = 0.002 which are combined in the negative have no correlation. Correlation of Sea Surface Temperature (SST) and Sea Surface Salinity (SSS) in all domains obtained a correlation of r = 0.40 which includes a moderate positive correlation. While the correlation in the offshore section, the results of the correlation r = -0.14 are classified as positive and have no correlation. Based on the relationship between the three variables, it can be modeled using a linear regression model, a polynomial regression of order 2 and a pulinomial of order 3. The model results show that the highest coefficient of determination is regression polynomial 3 with the coefficient of determination between SSS and chlorophyll-a of R2 = 0, 15, the SST and chlorophyll-a variables were R2 = 0.11 and the SST and SSS variables were R2 = 0.24.
