Topic 4C - Marine Safety

An output image from the processor side-by-side with a true colour RGB composite from Copernicus Sentinel-2 of the plastic target. The Copernicus Sentinel-2 pixel, mostly covered by the target, is flagged by the processor in yellow, as likely containing plastic.

Sentinel-2 imagery of plastic pollution off the coast of Ghana. The top image is an enchanced 'true colour' image, and the bottom image uses the Floating Debris Index (FDI) which helps the plastic debris become more visable

Top: A frontal area east of the Po River Delta, Italy. Bottom: litter strands after land-based rainfall events on an area south Calabria, Italy (bottom left image has been processed with the sea mask removed to show visible RGB rendering of the sea surface, where floating marine debris can be seen highlighted in red).
