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

Accompanying measures

Legal basis

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.

• 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:

Routine monitoring of European seas for illegal discharges in co-operation with Coastal States;

Support in case of an accidental spill; Investigation of pollution ‘hot spots’ and development of statistics.

• Sustainability• Cost Sharing

Reduced price for a large amount of images• Cooperation

Mutual benefits for coastal states Sharing of images and aerial surveillance

• European standardised service All European waters: comprehensive information & easy to compare

Scope & benefits of EMSA satellite service

CleanSeaNet Operational Support - Emergencies: New Flame

To monitor the New Flame incident (Sept. 07), EMSA specifically ordered ENV & RS1 scenes and issued CleanSeaNet briefings to the Spanish Authorities (SASEMAR), to DG ENV (MIC) and DG TREN

23

CSN: the international institutional context• Development of the service:

European Space Agency (ESA): MARCOAST, Data Access Joint Research Centre (JRC - European Commission)

• Operational cooperation (emergency): MIC, DG Environment, European Commission International Charter on Space and Major Disasters

– The ‘Charter’ is a mechanism to co-ordinate space based data acquisition and delivery to those affected by a natural or man made disaster anywhere in the world (earthquakes, floods, fires..)

– Charter Members –CSA, CNES, ESA, NOAA, JAXA, ISRO…– In the case of a large oil spill in European waters, EMSA will be

the focal point for producing Charter Products, e.g. Strafjord-A Platform accident in Norway, Dec. 07.

24

Improvement & further developments of CSN: Cooperation with JRC

• JRC provides R&D support to EMSA related to oil pollution and is currently developing:

Fully automatic oil spill identification system Study on the operational use of optical imagery (MODIS) for

oil spill detection Environmental ancillary probability maps as an overlay to

CleanSeaNet products

Several MODIS products showing algae blooms

CleanSeaNet: service development• In-house capability of combination with AIS (SRIT) (2008). AIS

Mediterranean regional server

• Capability of forecasting and hindcasting of spill drift, aging of spills (2008)

• Correlation of vessel tracks and spill movements needed

• EMSA service might be the first operational end-to-end service for Member States under GMES

• Service could be further developed for vessel detection/identification by satellite

• Long Range Identification & Tracking ?
