Abstract

ABSTRACTSalinity is the total concentration of ions found in water. Salinity is important for the survival of organisms. Almost all marine organisms can only live in areas that have small changes in salinity. The aim of this research is to determine the distribution pattern of salinity in Spermonde waters in 2022 and to find out a comparative picture of the salinity distribution pattern on Kapoposang Island, Samatellu Lompo Island, Kuninggareng Lompo Island and Lanyukang Island in Spermonde waters in 2022. This research was conducted from August to October 2023 in Hasanuddin University Makassar, Makassar City, South Sulawesi Province. Research was conducted at the Indraja Laboratory, Faculty of Marine and Fisheries Sciences. The data used was satellite image data, namely CMEMS satellite image. The pattern of salinity distribution in Spermonde Waters with an average value of 34.04 ppt is the highest salinity in August, and for the average value of salinity distribution of 32.52 ppt is in January. The comparison pattern of salinity distribution in 2022 on Kapoposang Island, Lanyukang Island, and Samatellu Lompo Island has the same average value, namely the lowest January and the highest August, except for Koninggarang Lompo Island the highest average value is in September and the lowest is in January.Keywords: Salinity, Kapoposang Island, Lanyukang Island, Koninggareng Lompo Island, Samatellu Lompo Island

Abstract

ABSTRACTOne of the parameters determining productivity in the sea is chlorophyll-a. The fertility level of chlorophyll-a is closely related to the concentration of chlorophyll-a. The higher the concentration of chlorophyll-a, the higher the water fertility level, conversely, if chlorophyll-a is low, the water fertility level will also be low. One factor influencing growth rate and chlorophyll-a production is temperature. This research aimed to determine the distribution of chlorophyll-a and sea surface temperature based on season in 2022 in the waters of Bone Bay using quantitative descriptive method and geographic information analysis (GIS) procedure in the form of analysis of Aqua MODIS remote sensing image data. The research results showed that the highest distribution of chlorophyll-a occurred in the east season with a concentration of 0.06-2.04 mg/m³, while the lowest distribution of chlorophyll-a occurred in the west season with a concentration of 0.07-1.76 mg/m³. Meanwhile, the highest intensity sea surface temperature distribution occurred in the west season, which was 28.76-37.09 °C and the lowest sea surface temperature distribution fell in the east season, which was 27.13-33.62 °C. Spatial temperature variability and sea surface chlorophyll-a can be used as information about potential areas for fishing grounds.Key words: chlorophyll-a distribution, sea surface temperature, Bone Bay, Aqua MODIS
