Ocean Colour Climate Change: Approach Identification of Sea Level and Physical Conditions in Setokok Sea

Abstract

: Setokok Island located at the South of Batam City, Riau Islands, positioned at longitude coordinates 104.031520° and latitude 0.951068°. The data acquisition technique uses satellite altimeter imagery data, which utilizes level 3 terra fashionable satellite imagery data. The study results show a significant change between one season (east season) with the period of data acquisition in April and May 2020. Sea surface temperature value is 28.7 o C in April 2020 and 29.8 o C in May 2020. Chlorophyll A distribution has a value of 3.5 mg/l in April 2020 and 3.2 mg/l in May 2020. The transverse profile produced by taking into account the sea level in Setokok Sea yielding in the mean sea level height of 1.86 meters and the average sea level of 2.67 meters. These data show a significant form of bathymetry in Setokok Sea. This research shows that global climate change affects sea level. Furthermore, it involves primary water production and bathymetry value in Setokok Sea.
