Contiguous zone
Beyond the 12-nautical-mile (22 km) limit, there is a further 12 nautical miles (22 km) from the territorial sea baseline limit, the contiguous zone, in which a state can continue to enforce laws in four specific areas: customs, taxation, immigration and pollution, if the infringement started within the state's territory or territorial waters, or if this infringement is about to occur within the state's territory or territorial waters.[4] This makes the contiguous zone a hot pursuit area.
Exclusive economic zones (EEZs)
These extend from the edge of the territorial sea out to 200 nautical miles (370 kilometres; 230 miles) from the baseline. Within this area, the coastal nation has sole exploitation rights over all natural resources. In casual use, the term may include the territorial sea and even the continental shelf. The EEZs were introduced to halt the increasingly heated clashes over fishing rights, although oil was also becoming important. The success of an offshore oil platform in the Gulf of Mexico in 1947 was soon repeated elsewhere in the world, and by 1970 it was technically feasible to operate in waters 4000 metres deep. Foreign nations have the freedom of navigation and overflight, subject to the regulation of the coastal states. Foreign states may also lay submarine pipes
and cables.
here's a nice article that describes both contiguous zone and the exclusive economic zone:
http://www.nationalreview.com/articles/ ... niel-pipes"...Were Athens to claim its full EEZ, Kastelorizo’s presence would make its EEZ contiguous with the EEZ of Cyprus, a factor with great import now, at a moment of massive off-shore gas and oil discoveries. Kastelorizo with an EEZ benefits the emerging Greece-Cyprus-Israel alliance by making it possible to transport either Cypriot and Israeli natural gas (via pipeline) or electricity (via cable) to Western Europe without Turkish permission. ..."
Under the rules of the EEZ Greece and Cyprus do have a common border and could sign an agreement to explore their offshore hydrocarbons. Its been noted before in the forum that during the invasion of Cyprus in 1974, the Turks offered to withdraw their troops to a corridor linking Kyrenia and Nicosia if Greece turns over the island of Kastelorizo, the Greeks rightly refused the offer and called on all Turkish troops to withdraw from Cyprus. And in fact the issue of Kastelorizo and the EEZ of Greece, Cyprus and Turkey was an issue among them even before the invasion of Cyprus in 74.
Delimitation of the continental shelf – the stretch of sea- bed beyond the territorial sea of a coastal state and what lies under it36 – became a prospective bone of contention between Turkey and Greece in 1973, as both focused on potential oil resources in the
Aegean with the onset of the first oil crisis. This coincided with rising tensions over Cyprus in 1974.
Therefore one could rightly conclude that with the invasion of Cyprus and continued occupation of one third of the island, that Turkey and Britain expected the Greeks and Greek Cypriots to acquiesce to an agreement giving the Turks Kastelorizo and Britain access to Cyprus' oil reserves, in exchange for the partial withdraw of Turkish troops from Cyprus.
