6. The probable degree of accuracy of the estimated position. 7. Weather conditions at above time. 8. Remarks, if any. 9. Signature of master or responsible navigating officer. There is no charge for bearings furnished by the United States naval radio-compass stations. Radiotelegraphic weather broadcasts.-The United States Weather Bureau issues daily (Sundays and holidays included) bulletins containing weather reports, forecasts, and warnings for the benefit of marine and aviation interests, which are broadcast from radio stations on the Atlantic coast. Major bulletins.-These bulletins are broadcast from the Arlington (Va.) Naval Radio Station (call letters NAA) twice daily, as follows: Morning bulletin at 10 a. m. (75th meridian) (1500 GCT) on 68 kc., 113 kc., and 16,120 kc. (continuous waves modulated at audible frequency), simultaneously. Evening bulletin at 10 p. m. (75th meridian) (0300 GCT) on 68 kc. and 113 kc. (continuous waves modulated at audible frequency) simultaneously. The bulletins are divided into two parts and invariably begin with the words "Weather Bureau bulletin." The first part consists of surface weather conditions based upon observations taken at 8 a. m. and 8 p. m. Weather reports from ships in the Atlantic Ocean, and during the hurricane season additional ship reports from the Gulf of Mexico and Caribbean Sea, follow the reports from land stations in the first part of the bulletin, as follows: In the afternoon bulletin-7 a. m. reports received too late for inclusion in the morning bulletin, and 7 p. m. reports, both of current day. In the morning bulletin―7 p. m. reports of previous day received too late for inclusion in afternoon bulletin, and 7 a. m. current-day reports. NOTE.-Ship reports of previous observation included only when conditions are unusual. The second part of the bulletin consists of a summary of general atmospheric pressure distribution over land and sea, including the locations of "high" and of "low areas and the barometer readings at their centers; wind and weather forecasts for Atlantic and Gulf of Mexico offshore areas; and storm warnings for these areas. The weather reports contained in the bulletins and supplemented by others picked up from vessels can be used in the production of weather maps, which will be of much value to navigating officers; and charts prepared for this purpose, which show the reporting stations and their key letters, will be forwarded upon application to the United States Weather Bureau. Complete details relative to the above service, including method of decoding the major bulletins and a list of stations from which localized broadcasts are made, are published in Circular No. 13, issued by the United States Weather Bureau. Copies of this circular may be obtained without charge upon application to any United States Weather Bureau office on the Atlantic coast. A new edition of the Radio Weather Code, for Vessel Weather Observers (W. B. 860) was published in 1925. Additional broadcasts are made from the following stations: Baltimore, Md. (WMH), 418 kc. (A2), 10.30 a. m. Norfolk, Va. (NAM), 122 kc. (A2), 8.30 a. m. and 8.30 p. m.; also 4 a. m., 11 a. m., and 4 p. m. Wind and weather conditions at Sandy Hook, N. J., are broadcast from radio stations as follows: New York, N. Y. (NAH), 102 kc. (A1), 10.30 a. m. Chatham, Mass. (WIM), 406 kc. (A1), 9 a. m. and 5 p. m. This information includes barometric pressure and tendency, temperature, wind direction and velocity and tendency, visibility, cloudiness, and state of sea at Sandy Hook. The information is also given by the radio stations to vessels whenever requested. Free medical advice to seamen by radio.-Through the efforts of the Seaman's Church Institute of New York, in cooperation with the United States Public Health Service, the Radio Corporation of America has undertaken to furnish radio medical advice for the benefit of sick and injured persons on ships (of all nationalities) at sea. In addition to the marine coastal stations furnishing this service, all vessels served or controlled by the Radio Corporation of America and the United Fruit Co. or the Tropical Radio Telegraph Co. will assist in the transmission of messages, or, if carrying a doctor, will furnish radio medical advice. The stations of these companies give preference to medical radiograms over all other messages except distress calls. There is no charge whatever either for the medical advice furnished or for the radio service in connection therewith. The following stations of the Radiomarine Corporation of America on the east coast of the United States are at all times ready to furnish medical advice: Messages requesting medical advice should be signed by the master of the vessel and should state briefly but clearly the symptoms shown by the afflicted person. Operators should indicate the number of words in the message and use the prefix "DH MEDICO." The following information on this subject has been furnished by the United Fruit Co.: The following is a list of radio stations of the United Fruit Co. and affiliated companies through which medical service may be obtained without charge, so far as these companies are concerned, by ships of all nationalities: Call letters subject to change in near future to comply with International Regulations. Radiograms requesting medical advice should be signed by the captain of the ship and should state briefly but clearly the symptoms of the person afflicted. Such radiograms, if intended for a United Fruit Co. hospital, should be addressed "UNIFRUITCO," followed by the name of the place where the hospital is located. United Fruit Co. hospitals giving this service are located at the following points and may be reached through any of the above-mentioned radio stations: Santa Marta, Columbia; Puerto Limon, Costa Rica; Almirante, Panama; Preston, Cuba; and Puerto Barrios, Guatemala. The Tela Railroad Co. hospital is located at Tela, Honduras, and may be reached by calling "TELARAILCO TELA." The Truxillo Railroad Co. maintains a hospital at Puerto Castilla, Honduras, for which point messages should be addressed "TRURAILCO CASTILLA.” The Miami and New Orleans stations of the Tropical Radio Telegraph Co. are in a position to render medical advice through their connections with hospitals in those cities. Messages for Miami should be addressed to the radio station there, and those for New Orleans should be addressed" UNIFRUITCO NEWORLEANS." All United Fruit Co. passenger steamships carry doctors, and free medical advice may be secured by radio from any of them by a radiogram addressed Ship's doctor," followed by the name of the steamship. 66 This free medical service is established primarily for the benefit of ships not carrying doctors. However, should occasion require, ships' doctors may hold consultation by radio with the United Fruit Co. ships' doctors and hospital staffs. The physicians and surgeons comprising the medical staff of the United Fruit Co. and its associated companies are thoroughly qualified, but in view of the fact that radio medical advice to ships at sea is given free and without an opportunity for a personal examination of the patients, no responsibility will be assumed by either the United Fruit Co. and its associated companies or the physicians or surgeons giving the advice as to its accuracy or for error or delay in the receipt or transmission of any message sent or received in connection therewith. It is requested that when sending medical advice radiograms, radio operators check them" (number of words) DH MEDICO." "DH MEDICO" radiograms will be given preference over all other radiograms, except S O S calls, throughout the radio service of the United Fruit Co. and affiliated companies. Medical advice will be phrased in language intelligible to a layman. Complete details relative to the service furnished by all companies are published in the manual " Ship Sanitation and First Aid " issued by the Seaman's Church Institute of New York. This information includes diagrams and a list of symptoms to be considered in TE preparing messages. Information on this subject is also included in the 1929 edition of "The Ship's Medicine Chest and First Aid at Sea" published by the United States Public Health Service. UNITED STATES COAST GUARD STATIONS Coast Guard stations in the region covered by this volume are listed in the following table. The stations are fully manned throughout the year and are supplied with boats, wreck guns, beach apparatus, and all other appliances for affording assistance in case of shipwreck. Instructions to enable mariners to avail themselves fully of the assistance thus afforded will be found in the appendix, page 282. The Coast Guard stations are provided with the International Code Signals and are prepared to send or receive signals in that code or by means of the Semaphore Code, the Occulting or Flashinglight Code, or the International Morse Wigwag Code. Telephone facilities are available at the stations for the summoning of Coast Guard cutters, tugs, or other assistance, or for communicating with telegraph lines.

When not influenced by the larger bays or rivers, such as Delaware River, Chesapeake Bay, and New York Bay, these tidal currents are weak, averaging about 0.2 knot at strength, the direction of the flood and ebb at strength being on and off shore, respectively. In the immediate vicinity of the larger bays or rivers, the direction of flood and ebb at strength is directly in and out, and the strength of the current is increased, depending on the proximity of the mouth. These three rivers and bays affect the direction of the tidal currents to a distance of about 20 miles from their entrances, 89926-30-3 |
