NOTES:

AIDS TO NAVIGATION
Consult U.S. Coast Guard Light List for supplemental information concerning aids to navigation.


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, Canadian Hydrographic Service, and the Japanese Hydrographic Department.

 
WARNING - PRUDENT MARINER
The prudent mariner will not rely solely on any single aid to navigation, particularly on floating aids. See United States Coast Guard Light List and United States 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 United States Coast Guard facility if telephone communication is impossible (33 CFR 153).


CAUTION - TEMPORARY CHANGES
Temporary changes or defects in aids to navigation are not indicated. See Local Notice to Mariners.


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 - 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.


VESSEL TRAFFIC SERVICE
Recommended traffic lanes established for approaches to San Francisco Bay are shown on charts 18645, 18680 and 18640. Recommended traffic lanes established in Santa Barbara Channel are shown on charts 18740 and 18720. Recommended traffic lanes established for approaches to the Strait Juan De Fuca are shown on charts 18480, 18400 and 18465.


VESSEL TRAFFIC SERVICE
Recommended traffic lanes established in Prince William Sound are shown on NOS charts 16707, 16708, 16709 and 16700.


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.
