RIASSUNTO

Biogenic oil film is a natural surface film that is usually derived from marine flora and fauna and has been frequently observed around aquaculture facilities. The purpose of this study is to investigate the possibility of detecting biogenic oil films near aquaculture facilities using SAR data. An automated procedure was developed for downloading, processing, classifying and extracting vectors that can be used for further analysis. Our dataset consisted of 257 Sentinel-1 SAR images for a one-year period (November 2019-November 2020), and a Python based automated algorithm was developed in order to detect the biogenic oil film and distinguish it from lookalikes. The algorithm was tested in Kratigos, Lesvos Island, Greece. Our first results indicate the existence of the film near aquaculture farms and the strong need for further investigation of its impacts to the coastal zone environment and activities.
