Fig. 1 - S1 (14.10.2014) – VV polarisation with histogram equalization processing.
Fig. 2 - S1 (18.01.2016), multiple flowlines spills can be identified East of the USAN FPSO.
Fig. 3 - S1 (03.10.2016), smaller flowlines spills remain ponctual dark spots.
Fig. 4 - S1 (07.01.2017), surface spills are identified by the presence of a nearby bright point highlighting a vessel.
Fig. 5 - S1 (01.03.2017), bigger spills spread in parallel patterns according to current and wind.
Fig. 6 - Full stack with decreasing opacity shows still objects (platfoms and FPSOs) and recurrent spills.
