Ship/shore radio contact

Within national waters, rivers, ports and roads, exchange of information in connection with the above is to be maintained in accordance with Prefectura Naval (Coastguard) Ordinance 6/82 known under the acronym 'SECOSENA' or Communications Service for Navigational Safety (Servicio de Comunicaciones para la Seguridad de la Navegación). Furthermore this system is complemented by its sub-system 'CONTRASE' (Control de Tráfico y Seguridad) or Safety and Traffic Control. Search and Rescue (SAR) operations are coordinated by the Argentine Navy (see paragraph on SAR).
