Mapping of Sea Surface Temperature and its Correlation with Salinity Concentration in The Coastal Beach of Bangkalan Madura District

Abstract

Sea surface temperature is one of the parameters that plays a role in the quality of aquatic ecosystems in the sea, especially in shallow marine waters. Other parameters that play a role in determining the quality of the soil on the coast are salinity concentrations, which defines the mineral content of salts that are in the structure of soil widely used for farming or for ponds. This study aims to obtain a correlation of salinity to changes in temporal sea surface temperature for 2 consecutive years on the coastal areas of Bangkalan Madura district as a case study. The method used in this study was mapping with remote sensing using Terra Modis satellite imagery for 2018 and 2019. The acquisition of SST data used the ATBD algorithm and field data while for salinity field data were used. The study found that the magnitude of the SST values during the temporal analysis was not too much different in 2018 and 2019, only for correlations with salinity, the statistically calculated error rate of 5% showed that there were sufficient differences with the SST changes that occured during a year. The conclusion is that there was a significant correlation of the amount of salinity concentration with changes in sea surface temperature that occurred during the year of observation and this requires serious handling so that high salinity in coastal areas do not seep into the land which would have a negative impact on coastal communities.
