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. 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 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. SUPPLEMENTAL INFORMATION Consult U.S. Coast Pilot 7 for important supplemental information. CAUTION - TEMPORARY CHANGES Temporary changes or defects in aids to navigation are not indicated. See Local 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. ADDITIONAL INFORMATION Additional information can be obtained at www.nauticalcharts.noaa.gov AUTHORITIES Hydrography and topography by the National Ocean Service, Coast Survey, with additional data from the National Geospatial-intelligence Agency, Corps of Engineers, U.S. Coast Guard, British Admiralty, Canadian Hydrographic Service, and the Japanese Hydrographic Department. HORIZONTAL DATUM The NOAA ENC references the World Geodetic System of 1984 (WGS-84). For charting purposes, the horizontal control of the current realization of WGS-84 is functionally equivalent to the International Terrestrial Reference Frame 2020 (ITRF2020) at the meter level for charts at scales of 1:5,000 or smaller. CAUTION - LARGE SCALE CHARTS Danger, Prohibited, and Restricted Areas falling within the limits of the larger scale charts are shown thereon and not reported. CAUTION - QUALITY OF BATHYMETRIC DATA The areas represented by the object M_QUAL (Quality of data) are approximate due to generalizing for clarity. Caution is advised, particularly for nearshore navigation or voyage planning. M_QUAL represents areas of uniform quality of bathymetric data. The CATZOC (Category of zone of confidence in data) attribute of M_QUAL provides an assessment of the overall zone of confidence. CAUTION - SUBMARINE OPERATING AREAS Submerged Submarine Operating Areas falling within the limits of the larger scale charts are shown thereon and not repeated. 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. MARITIME BOUNDARY Any international maritime boundary shown in the disputed area is without prejudice to the legal position of the United States or Canada. 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. Avalon, CA WNG-584 162.525 MHz Big Rock Ridge, CA KDX-54 162.500 MHz Contra Costa County, CA WNG-655 162.425 MHz Los Angeles, CA KWO-37 162.550 MHz Malibu Marine, CA KWL-22 162.425 MHz Monterey Marine, CA WWF-64 162.450 MHz Monterey, CA KEC-49 162.550 MHz Point Arena, CA KIH-30 162.550 MHz Sacramento, CA KEC-57 162.550 MHz San Diego Marine, CA WNG-637 162.425 MHz San Diego, CA KEC-62 162.400 MHz San Francisco, CA KHB-49 162.400 MHz San Luis Obispo, CA KIH-31 162.550 MHz San Simeon, CA WNG-592 162.525 MHz Santa Ana, CA WWG-21 162.450 MHz Santa Barbara Marine, CA WWF-62 162.475 MHz Santa Barbara, CA KIH-34 162.400 MHz Sonoma County, CA WZ-2504 162.475 MHz Victorville, CA WXM-66 162.500 MHz 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. VESSEL TRAFFIC SERVICE Recommended traffic lanes established for approaches to San Francisco Bay are shown on larger scale charts. Recommended traffic lanes established in Santa Barbara Channel are shown on larger scale charts. VESSEL TRANSITING The U.S. Coast Guard and the Pacific States/British Columbia Oil Spill Task Force endorse a system of voluntary measures and minimum distances from shore for certain commercial vessels transiting along the coast anywhere between Cook Inlet, Alaska and San Diego, California. See U.S. Coast Pilot 7, Chapter 3 for details. 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.
