NOAA ENCŪ NATIONAL OCEANIC AND ATMOSPHERIC ADMINISTRATION US3HA20M - HAWAI'I TO O'AHU INDEX: NOTE A AIDS TO NAVIGATION CAUTION - TEMPORARY CHANGES WARNING - PRUDENT MARINER NOAA WEATHER RADIO BROADCASTS AUTHORITIES NOTE B NOTE E CAUTION - FISH AGGREGATING DEVICES POLLUTION REPORTS CAUTION - USE OF RADIO SIGNALS (LIMITATIONS) CAUTION - SUBMARINE PIPELINES AND CABLES SUPPLEMENTAL INFORMATION ADDITIONAL INFORMATION WATER LEVELS, CURRENTS, AND TIDES COMMENTS REQUESTED RADAR REFLECTORS NOTES: NOTE A Navigation regulations are published in Chapter 2, U.S. Coast Pilot 10. Additions or revisions to Chapter 2 are published in the Notice to Mariners. Information concerning the regulations may be obtained at the Office of the Commander, 14th Coast Guard District in Honolulu, Hawaii or at the Office of the District Engineer, Corps of Engineers in Honolulu, Hawaii. Refer to charted regulation section numbers. AIDS TO NAVIGATION Consult U.S. Coast Guard Light List for supplemental information concerning aids to navigation. CAUTION - TEMPORARY CHANGES Temporary changes or defects in aids to navigation are not indicated on this chart. See Notice to Mariners. WARNING - PRUDENT MARINER The prudent mariner will not rely solely on any single aid to navigation, particularly on floating aids. See U.S. Coast Guard Light List and U.S. Coast Pilot for details. NOAA WEATHER RADIO BROADCASTS The National Weather Service stations listed below provide continuous marine weather broadcasts. The range of reception is variable, but for most stations is usually 37 to 74 kilometers / 20 to 40 nautical miles from the antenna site, but can be as much as 185 kilometers / 100 nautical miles for stations at high elevations. Mt. Kaala KBA-99 162.55 MHz Hawaii Kai KBA-99 162.40 MHz Mt. Haleakala KBA-99 162.40 MHz Kulani Cone KBA-99 162.55 MHz Reception in some areas will be poor or even impossible due to obstruction of the FM radio signal by mountains. AUTHORITIES Hydrography and topography by the National Ocean Service, Coast Survey, with additional data from the Corps of Engineers, Geological Survey, U.S. Coast Guard, National Geospatial-Intelligence Agency, and U.S. Navy. NOTE B Submerged submarine operations are conducted at various times in the waters contained on this chart. Proceed with caution. NOTE E Fish Aggregating Devices (FADS) Buoys outside 3 NM may have a swing circle radius of up to 3.5 NM from their charted position. Mariners are advised to use caution when transiting in the vicinity of FAD Buoys. CAUTION - FISH AGGREGATING DEVICES Fish Aggregating Devices (FADs) are established along the coastal waters of the main Hawai'ian Islands POLLUTION REPORTS Report all spills of oil and hazardous substances to the National Response Center via 1-800-424-8802 (toll free), or to the nearest U.S. Coast Guard facility if telephone communication is impossible (33 CFR 153). CAUTION - USE OF RADIO SIGNALS (LIMITATIONS) Limitations on the use of radio signals as aids to marine navigation can be found in the U.S. Coast Guard Light Lists and National Geospatial-Intelligence Agency Publication 117. Radio direction-finder bearings to commercial broadcasting stations are subject to error and should be used with caution. CAUTION - SUBMARINE PIPELINES AND CABLES Additional uncharted submarine pipelines and submarine cables may exist within the area of this chart. Not all submarine pipelines and submarine cables are required to be buried, and those that were originally buried may have become exposed. Mariners should use extreme caution when operating vessels in depths of water comparable to their draft in areas where pipelines and cables may exist, and when anchoring, dragging or trawling. Covered wells may be marked by lighted or unlighted buoys. SUPPLEMENTAL INFORMATION Consult U.S. Coast pilot 10 for important supplemental information. ADDITIONAL INFORMATION Additional information can be obtained at www.nauticalcharts.noaa.gov WATER LEVELS, CURRENTS, AND TIDES Real-time water levels, tide predictions, and tidal current predictions are available on the internet from NOAA's Center for Operational Oceanographic Products and Services (CO-OPS) at https://tidesandcurrents.noaa.gov/water_level_info.html and https://tidesandcurrents.noaa.gov/currents_info.html. COMMENTS REQUESTED NOAA encourages users to submit inquiries, discrepancies, or comments about this chart via NOAA's ASSIST tool at https://www.nauticalcharts.noaa.gov/customer-service/assist/. RADAR REFLECTORS Radar reflectors have been placed on many floating aids to navigation. Individual radar reflector identification on these aids has been omitted from this chart. END OF FILE
