ANALYSIS DISTRIBUTION OF SEA SURFACE TEMPERATURE AND CHLOROPHYLL-a CONCENTRATION IN BELAWAN MEDAN NORTH SUMATRA

Abstract

Sea surface temperature (SST) and chlorophyll-a are important water quality
parameter in the sea, especially the coastal areas. The research was conducted in
January - March 2017 in the waters of Belawan, North Sumatera Province with the
aim to determine the relationship of sea surface temperature and chlorophyll
concentrations-a.The method used is survey with direct measurements in the waters
of Belawan, North Sumatera and using MODIS Aqua satellite image data in March
2016 - February 2017. Sea surface temperature MODIS Aqua satellite image data
in March 2016 - February 2017 ranged from 29.45 to 31.7oC and chlorophyll-a
range of 0.48 to 2.62 mg / l. Field data sea surface temperature ranges from 26-30°C
and chlorophyll-a range of 2.08 to 17.62 mg / l. Interpretation of the data from the
MODIS Aqua satellite imagery and field data to explain that the sea surface
temperature and chlorophyll concentrations-a very weak, r = 0.1791. Data were
mapped to show the variability of sea surface temperature and chlorophyll-a
concentrations March 2016 until February 2017.
