Spatial and Temporal Analysis of Oceanographic Parameters and Their Relationship with Upwelling Phenomena in Seram Sea and Buru Island Waters

The waters of the Seram Sea and Buru Island are comparatively rich in resources and productivity. However, many fishermen continue to rely on intuition or instinct to locate fishing spots. Therefore, understanding the significance of oceanographic parameters as indicators of water's primary productivity is crucial. This study utilizes data from January 2010 to December 2020, including oceanographic parameters such as sea surface temperature (SST) and chlorophyll-a concentration from AQUA-MODIS satellite imagery, wind data from ECMWF reanalysis, and fish catch data from Fishing Spot Galala-Hative Kecil.The research aimed to examine the variability of sea surface temperature, chlorophyll-a, and surface winds, and their relationship with the upwelling phenomenon in Seram Sea waters and Buru Island. Data were processed spatially using script methods in the Grads 2.2.1 application and temporally using statistical methods in MS Excel, followed by correlation analysis using Pearson correlation.The results indicate that sea surface temperature, chlorophyll-a, and winds exhibit greater variability from May to August. Upwelling potential in these waters occurs from June to August and continues through September and October, characterized by strong upwelling. This is evidenced by low sea surface temperatures ranging from 26°C to 27.7°C, chlorophyll-a concentrations ranging from 0.5 to 1.2mg/l, and wind speeds during this period ranging from 3.9 to 6.4m/s. Additionally, correlation tests reveal that sea surface temperature and chlorophyll-a in the study area from May to August have a linear correlation with fish catch (CPUE), with values of 0.52 and 0.56, respectively.
