Additions or revisions to Chapter 2 are published in the Notice to Mariners. Information concerning the regulations may be obtained from the Coast Guard District Commander. Refer to charted regulation section numbers. AIDS TO NAVIGATION Consult U.S. Coast Guard Light List for supplemental information concerning aids to navigation. 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. CAUTION - DREDGED AREAS Improved channels are subject to shoaling, particularly at the edges. CAUTION - TEMPORARY CHANGES Temporary changes or defects in aids to navigation are not indicated. See Local Notice to Mariners. 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. 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. COLREGS International Regulations for Preventing Collisions at Sea, 1972. The entire area of this chart falls seaward of the COLREGS Demarcation Line. NOAA WEATHER RADIO BROADCASTS The NOAA Weather Radio stations listed Below provide continuous weather broadcasts. The reception range is typically 20 to 40 nautical miles from the antenna site, but can be as much as 100 nautical miles for stations at high elevations. CITY STATION FREQUENCY San Juan, PR WXJ-69 162.400 MHz St. Croix, VI WNG-677 162.500 MHz 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). SUPPLEMENTAL INFORMATION Consult U.S. Coast Pilot 5 for important supplemental information. AUTHORITIES Hydrography and topography by the National Ocean Service, Coast Survey, with additional data from the Corps of the Engineers, Geological Survey, and U.S. Coast Guard. CAUTION - 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. HURRICANES AND TROPICAL STORMS Hurricanes, tropical storms and other major storms may cause considerable damage to marine structures, aids to navigation and moored vessels, resulting in submerged debris in unknown locations. Charted soundings, channel depths and shoreline may not reflect actual conditions following these storms. Fixed aids to navigation may have been damaged or destroyed. Buoys may have been moved from their charted positions, damaged, sunk, extinguished or otherwise made inoperative. Mariners should not rely upon the position or operation of an aid to navigation. Wrecks and submerged obstructions may have been displaced from charted locations. Pipelines may have become uncovered or moved. Mariners are urged to exercise extreme caution and are requested to report aids to navigation discrepancies and hazards to navigation to the nearest United States Coast Guard unit. 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. 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 . ADDITIONAL INFORMATION Additional information can be obtained at www.nauticalcharts.noaa.gov . CORAL PROPAGATION Uncharted submerged manmade structures, designed for the purpose of coral propagation, may exist within the limits of this chart, principally in shallow water areas.
