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, 17th Coast Guard District in Juneau, Alaska, or at the Office of the District Engineer, Corps of Engineers in Anchorage, Alaska. Refer to charted regulation section numbers. 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, and National Geospatial-Intelligence Agency. 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. 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 9 for important supplemental information. CAUTION - TEMPORARY CHANGES Temporary changes or defects in aids to navigation are not indicated. See Local Notice to Mariners. 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. Raspberry I, AK KZZ-90 162.425 MHz Bede Mt, AK WNG-528 162.450 MHz Pillar Mt, AK WNG-531 162.525 MHz Kodiak, AK WXJ-78 162.550 MHz Marmot Island, AK WNG-716 162.500 MHZ COLREGS, 80.1750 International Regulations for Preventing Collisions at Sea, 1972. The entire area of this chart falls seaward of the COLREGS Demarcation Line. 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. 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 - 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. CAUTION - SIGNIFICANT CHANGES Significant changes in depths and shoreline have occurred in the area of this chart as a result of the earthquake of March 27, 1964. Charted hydrography in the vicinity of Kodiak Harbor is from post earthquake surveys. Tidal observations since the earthquake indicate bottom subsidence of -1.7 meters/-5.6 feet at Womens Bay. Mariners are urged to use extreme caution when navigating in other areas of this chart. 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. 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.
