The UNCLOS defines the high sea as "all parts of the sea that are not included in the Exclusive Economic Zone, in the territorial sea or in the internal waters of a State […]" . In the Mediterranean, the distance between the baselines of States opposite each other is everywhere less than 400 nautical miles. Which means that if all the coastal States declared an Exclusive Economic Zone (EEZ), there would no longer be a high sea. Entirely under jurisdiction, the marine area thus established would open up new perspectives for protection of the environment and governance (cf. Jurisdictionalisation).
