        1.        The ESF watch on duty in the Joint Operations area will consist of the following personnel, whose duties are as indicated.
Title Duties
Surface Controller         The Surface Controller on watch is the Operations Action Officer for surface activities of the Commander Eastern Sea Frontier. The Surface Controller while on watch heads the Operational Information functions of the Frontier. He maintains continuous close liaison with the Air Controller, and detailed cognizance of all important surface activities which are in progress, or immediately pending, throughout the Eastern Sea Frontier.
          (a) The primary duty of the Surface Controller is to see that prompt and vigorous action is taken in regard to enemy contacts. It is not enough that the Surface Controller merely check with the Naval District involved. He must be familiar with the craft available to the District (daily availability lists) and satisfy himself that all units are being used to best advantage, suggesting or, if necessary, ordering the dispatch of additional craft to the scene. Obtaining assistance from the other Districts or making requests to Cinclant for aid to meet a particular situation are action items on which he must be prepared to make decisions.
          (b) On being convinced of definite enemy activity within the waters of the Eastern Sea Frontier, the following action shall be taken by the Surface Controller:
                  (I) Notify the Commander Eastern Sea Frontier, Chief of Staff, Operations Officer and others interested.

                  (II) Notify the Commander-in-Chief, U.S. Fleet. In this connection use sub-tracking teletype as the most rapid secure method. If this means is not available, and urgency demands rapid transmission, use command telephone.
                  (III) Notify ESF Task Group Commanders and Task Unit Commanders who need to know by usual methods.
                  (IV) Notify the Communications Watch Officer to subordinate handling of other traffic in order to expedite dispatches regarding enemy activity, and suggest he confer with Washington C.W.O. regarding situation.
                  (V) Send local war warning or specific diversion orders for merchant shipping in the vicinity of, or approaching the area in which contact has been made. The best method of disseminating a local war warning within 300 miles of New York is to transmit it via Amagansett, which is connected by direct wire to D.C.G.O. office. If a general warning to merchant ships is in order, it must be sent to Cominch for dissemination. The C.W.O. is prepared to handle such messages.
                  (VI) Make estimate of the situation and determine what additional attack forces can be brought into action.
                  (VII) Check that the Operational Information Section is fully informed and developing plots of all shipping within 150 miles of the contact are adjusted for position each hour until the situation is determined. Verify that action charts are maintained to the proper scale for evaluation purposes, and that periodic summaries of action are prepared.
                  (VIII) Check that the Coastal Information Section is fully informed, and that steps are taken to develop the flow of information from the Costal areas in regard to pertinent enemy action.
