The United Nations-Oceans (UN-Oceans or UN-O) is an inter-agency coordination mechanism of the United Nations, set up to enhance cooperation and coordination of activities concerned with the world oceans and coasts. The UN-Oceans was formed in September 2003 by the United Nations System Chief Executive Board (CEB), to replace the Sub-Committee on Oceans and Coastal Areas (SOCA) of the Administrative Committee on coordination (ACC) that was formed in 1993.
