Approximately 58.6%* of the sea surface is defined as High Seas. These are 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, or in the archipelagic waters of an archipelagic State, according to the definition provided by the Law of the sea.

MarineRegions.org is proud to release the first version of the High Seas, the last addition to the Maritime Boundaries dataset. You can download it in this link.
