Oil Slick Environmental Monitoring Service - Secondary Objective<br />
The detection of oil spills is coordinated at European level through the CleanSeaNet initiative. All<br />
information about oil detection is directed towards EMSA who has the mandate to track and survey<br />
illegal discharges at sea in order to intercept polluters. The system of oil observation is run in parallel<br />
with Automatic Identification Systems (AIS) and Vessel Monitoring System (VMS) that allows<br />
identification of polluters. The system is operational since 2007.<br />

The oil spill detection today relies especially on SAR images but should be complemented with<br />
ancillary information (such as SST and Ocean colour) in order to improve the level of confidence of the<br />
detection and corresponding reporting – this statement is especially valid in the Baltic where biogenic<br />
spills due to biological material may lead to misdetection of oil spills (see EMSA documentation and<br />
GSE-Marcoast phase 2 recommendation). This is the objective of the oil slick environmental<br />
monitoring service.<br />
