Objective: To exclude the sea bed, the ocean floor and the subsoil thereof from the arms race as a step towards disarmament, the reduction of international tensions and the maintenance of world peace.
Summary of provisions: Parties undertake not to place on the sea bed, on the ocean floor or in the subsoil thereof, nuclear weapons or other weapons of mass destruction, or structures for launching, storing, testing or using such weapons (art. 1). The outer limit of the seabed zone is defined as the 12-mile limit referred to in the Convention on the Territorial Sea and the Contiguous Zone, 1958 (art. 2). Observers from any Party may observe and verify the activities of any other Party on the seabed. In case of doubt Parties agree to consult and cooperate to remove such doubt by means of inspection and any other agreed procedures. If a serious question still remains concerning the fulfilment of the obligations under the Treaty, a Party may refer the matter to the United Nations Security Council (art. 3).
