The [Convention on the Law of the Sea, 1982] defines the boundaries of each part of the sea and the continental shelf and the legal regime applicable therein, the rights and conditions of passage for shipping through other states' waters, jurisdiction over ships on the high seas and exceptions to the freedom of the high seas and the legal and management regime for the exploitation of mineral resources on the deep-sea bed and ocean floor beyond national jurisdiction. The Parties are obliged to: (1) keep under surveillance the effects of any activities which they permit or in which they engage, in order to determine whether these activities are likely to pollute the marine environment; (2) follow up their commitment by actively enforcing national and applicable international standards with regard to all sources of pollution under their jurisdiction; (3) adopt measures for the conservation of living resources of marine pollution and cooperate in taking such measures for high-seas fisheries.
It is left to the Parties to devise the ways and means of individually or jointly pursuing systematic and ad-hoc monitoring programmes, taking into account similar programmes already established by other treaties and organizations. Many of the provisions of the Convention are codifications of customary law and therefore applicable to all states, irrespective of signature or ratification. The process of realisation of the Convention through many years worked as a catalyst encouraging an integrated approach to the sea. The General Assembly of the United Nations decided in Resolution 49/28 that it would evaluate the implementation of the Convention and review other developments relating to ocean affairs and the law of the sea on an annual basis.
