1 The United Nations Conference on the Law of the Sea met at Geneva from 24 February to 27 April 1958, resulting in the adoption of four separate conventions: the Convention on the Territorial Sea and the Contiguous Zone (United Nations, Treaty Series, vol.516, p. 205); the Convention on the High Seas (United Nations, Treaty Series, vol. 450, p. 11); the Convention on Fishing and Conservation of the Living Resources of the High Seas (United Nations, Treaty Series, vol. 559, p. 285); and the Convention on the Continental Shelf (United Nations, Treaty Series, vol.499, p311). These have been superseded by the 1982 United Nations Convention on the Law of the Sea (courtesy of the Oceans and Law of the Sea web site).
