Penelitian dengan judul “ Korelasi Sea Surface Salinity (SSS), Sea Surface Temperature (SST) dan Klorofil-a pada bulan Februari Tahun 2021 di Laut Andaman” merupakan penelitian baru yang pernah dilakukan di Laut Andaman. Sea Surface Salinity (SSS), Sea Surface Temperature (SST) dan Klorofil-a memiliki korelasi yang berbeda-beda di setiap perairan. Tujuan dari penelitian ini untuk mempelajari hubungan antara korelasi Sea Surface Salinity (SSS), Sea Surface Temperature (SST) dan Klorofil-a di Laut Andaman berdasarkan data hasil model 3d dari HYCOM (Hybrid Coordinate Ocean Model) dan data Klorofil-a diperoleh dari CMEMS (Copernicus Marine Environment Monitoring Service). Hasil dari penelitian ini menunjukkan bahwa nilai maksimum Sea Surface Salinity (SSS) 34 psu. Nilai maksimum Sea Surface Temperature (SST) yaitu 29oC dan nilai maksimum Klorofil-a yaitu 0.6 mg/m3. Berdasarkan hubungan antara Sea Surface Temperature (SST) dan klorofil-a pada seluruh domain menggunakan korelasi pearson diperoleh nilai R2 = 0.10 dan r = 0.33 menunjukkan hubungan yang positif lemah dan memperoleh nilai R2 = 0.111 menggunakan model regresi polinomial ordo 2 dan pada polinomial ordo 3 memperoleh nilai R2 = 0.119. Pada garis pantai hubungan SST dan Klorofil-a dianalisis menggunakan korelasi pearson diperoleh nilai R2= 0.002 dan r= -0.04 menunjukkan bahwa tidak ada hubungan dari kedua variabel tersebut memperoleh nilai R2= 0.15 pada regresi polinomial ordo 2 dan R2= 0.16 pada regresi polinomial ordo 3. Hubungan SSS dan Klorofil-a pada seluruh domain menunjukkan hubungan yang negatif lemah dengan nilai R2= 0.04 dan r= -0.20 regresi polynomial ordo 2 nilai R2= 0.06 dan regresi polinomial ordo 3 R2= 0.08. Pada garis pantai memperoleh nilai R2= 0.03 dan r= -0.18 pada regresi polinomial ordo 2 nilai R2= 0.05 dan regresi polinomial ordo 3 nilai R2= 0.06. Hubungan SST dan SSS memperoleh nilai R2= 0.0006 dan memperoleh ni r= 0.02 pada regresi polinomial ordo 2 nilai R2= 0.010 dan regresi polinomial ordo 3 dengan nilai R2= 0.011 sedangkan pada garis pantai hubunagn SSS dan SST menunjukkan hubungan yang negatif kuat dengan nilai R2= 0.47 dan nilai r= -0.69 pada regresi polynomial ordo 2 memperoleh nilai R2= 0.53 dan memperoleh nilai R2= 0.61 pada polynomial ordo 3.

Temperature (SST) and Chlorophyll-a in February 2021 in the Andaman Sea" is a new research that has been carried out in the Andaman Sea. Sea Surface Salinity (SSS), Sea Surface Temperature (SST) and Chlorophyll-a have different correlations in each water. The purpose of this study was to study the relationship between the correlation of Sea Surface Salinity (SSS), Sea Surface Temperature (SST) and Chlorophyll-a in the Andaman Sea based on 3d model results data from HYCOM (Hybrid Coordinate Ocean Model) and Chlorophyll-a data obtained obtained from CMEMS (Copernicus Marine Environment Monitoring Service). The results of this study showed that the maximum value of Sea Surface Salinity (SSS) was 34 psu. The maximum value of Sea Surface Temperature (SST) is 29oC and the maximum value of Chlorophyll-a is 0.6 mg / m3. Based on the relationship between Sea Surface Temperature (SST) and chlorophyll-a in all domains using pearson correlation obtained values R2 = 0.1097 and r = 0.33 shows a low positive relationship and obtains a value of R2 = 0.111 using a regression model of order 2 polynomials and in order 3 polynomials obtains a value of R2 = 0.1199. On the coastline, the relationship between SST and Chlorophyll-a was analyzed using pearson correlation obtained values R2 = 0.002 and r = -0.04 indicating that there was no relationship between the two variables obtained values R2 = 0.1573 in regression of polynomials of order 2 and R2 = 0.1616 in Polynomial regression of order 3. The relationship between SSS and chlorophyll-a in all domains showed a low negative relationship with R2 = 0.0431 values, order 2 polynomial regression R2 = 0.0627 and order 3 polynomial regression R2 = 0.0852, while on the coastline obtained R2 = 0.0326 values in order 2 polynomial regression R2 values = 0.055 and order 3 polynomial regression R2 values = 0.0649. The relationship between SST and SSS obtained the value of R2 = 0.0006 and obtained ni r = 0.02 in order 2 polynomial regression R2 value = 0.0101 and order 3 polynomial regression with R2 value = 0.0113 while on the coastline of SSS and SST connections showed a strong negative relationship with R2 value = 0.4773 and r value = -0.69 in order 2 polynomial regression obtained R2 value = 0.5377 and obtained R2 value = 0.6121 in order 3 polynomial.
