IMO List of MARPOL Special Areas and Particularly Sensitive Sea Areas
The International Maritime Organisation has released a circular under MEPC.1/Circ.778 listing the current status of all Special Areas as defined under Annexes I, II and V of the MARPOL Convention and the Emission Control Areas (ECAs) as defined under Annex VI of the MARPOL Convention.
Special Areas are defined as certain sea areas in which, for technical reasons relating to their oceanographical and ecological condition and to their sea traffic, the adoption of special mandatory methods for the prevention of sea pollution is required. Under the Convention, these special areas are provided with a higher level of protection than other areas of the sea.
The circular also lists the Particularly Sensitive Sea Areas (PSSAs) as defined by the Marine Environmental Protection Committee (MEPC) resolutions.
PSSAs are defined as areas that need special protection through action by the IMO because of their significance for recognised ecological, socio-economic, or scientific attributes, where such attributes may be vulnerable to damage by international shipping activities.
