Today our team gathered at Tsamakia beach at 9 am. This day, four targets (5x5m) were deployed in pairs (two targets covered with plastic bottles and the other two with plastic bags). There was a change on the coverage of the targets so that in this iteration each target was 50% covered by the plastic products. Furthermore there were two additional deployments, one target with dimensions 2x5m, covered 100% by plastic bottles and a 1 m^3 cube filled with 100 bottles and 100 bottle etiquettes.
All the targets were placed in the water at 09:30 am and by 10:28 am they were in their final positions. Sentinel-2 satellite overpassed approximately at 12 pm and several images were also taken from a drone, mounted with both an RGB camera and a SlantRange sensor. In addition, four GPS modules were mounted on the 5x5m targets in order to acquire accurate position data.
