The Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR) was established by international convention in 1982 with the objective of conserving Antarctic marine life. This was in response to increasing commercial interest in Antarctic krill resources, a keystone component of the Antarctic ecosystem and a history of over-exploitation of several other marine resources in the Southern Ocean. CCAMLR is an international commission with 26 Members, and a further 10 countries have acceded to the Convention. Based on the best available scientific information, the Commission agrees a set of conservation measures that determine the use of marine living resources in the Antarctic.

The Directive 2002/59/EC of the European Parliament and of the Council of 27 June 2002 requires the Member States (MSs) to provide themselves with appropriate equipment and shore-based installations for receiving and utilizing the AIS information transmitted by the vessels. The Member States agreed to implement common regional systems hosted and developed by one of them. EMSA and the Italian Coast Guard subscribed, since 2009, a Service Level Agreement (SLA) by which Italy is responsible for the hosting, maintenance, operation, and monitoring of the Mediterranean AIS Regional Server (MAREΣ) and its connection with SafeSeaNet. Part of SafeSeaNet, MAREΣ (Mediterranean AIS Regional Exchange System) officially started to run on 1st January 2008; currently it allows the AIS information sharing among Mediterranean EU countries (Portugal, Spain, France, Italy, Malta, Slovenia, Greece, Cyprus, Romania, Bulgaria, Croatia) and non-EU which agreed to share AIS data between themselves (e.g., Jordan, Morocco, and Montenegro).
