CleanSeaNet: The EU satellite service for monitoring and surveillance of illegal oil discharges 1 23 January 2008 SeaSAR 2008, ESA - ESRIN Samuel Djavidnia European Maritime Safety Agency [email protected] Outline • Legal basis • CleanSeaNet: scope & benefits • CleanSeaNet service cycle • CleanSeaNet results & statistics • Examples: routine monitoring / emergencies 2 • CleanSeaNet within the international context (cooperation) • Future service development Legal basis Mandated by Directive 2005/35/EC of 7 September 2005 on Ship-source pollution and on the introduction of penalties for infringements (entered into force on 1 March 2007) Article 10 3 Accompanying measures 2. In accordance with its tasks as defined in Regulation (EC) No 1406/2002, the European Maritime Safety Agency shall: (a) work with the Member States in developing technical solutions and providing technical assistance in relation to the implementation of this Directive, in actions such as tracing discharges by satellite monitoring and surveillance; (b) assist the Commission in the implementation of this Directive, including, if appropriate, by means of visits to the Member States, in accordance with Article 3 of Regulation (EC) No 1406/2002. Scope & benefits of EMSA satellite service • European system for detecting oil slicks at sea using satellite surveillance on request of the Commission and all EU and EFTA. • Links into national/regional response chain & strengthens operational pollution surveillance & response for accidental spills: ¾ Routine monitoring of European seas for illegal discharges in co- operation with Coastal States; ¾ Support in case of an accidental spill; 4 ¾ Investigation of pollution ‘hot spots’ and development of statistics. • Sustainability • Cost Sharing ¾ Reduced price for a large amount of images • Cooperation ¾ Mutual benefits for coastal states ¾ Sharing of images and aerial surveillance • European standardised service ¾ All European waters: comprehensive information & easy to compare Service cycle: CleanSeaNet: step by step • 1.
