Detection of Chlorophyll A on the Black Sea Coast with Sentinel-2 Satellite

It is costly and time-consuming to determine coastal pollution with ground measurements. One of the most basic parameters to determine pollution in these areas is Chlorophyll A. This study aims to investigate the determination of this parameter using Remote Sensing (RS) techniques. In the study, the Sentinel-2 satellite was used to determine the parameter Chlorophyll A in the coastal areas of the Black Sea. 19 algorithms were used in the application. The algorithms are related to luminance reflections and the 8 bands of the satellite were used for the study. An Artificial Neural Network model was published as the best result. Pollution was observed in the coastal areas of the Black Sea between 2021 and 2017. As a result of the analysis, it is possible to observe coastal pollution quickly, without cost and/or at very low cost, with RS techniques. In this sense, RS techniques are of great importance in detecting environmental pollution, and relevant algorithms should be developed and supported by local measurements.
