NOTES:


NOTE A 
Navigation regulations are published in Chapter 2, U.S. Coast Pilot 7.  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, 
11th Coast Guard District in Alameda, California or at the Office of the District 
Engineer, Corps of Engineers in Los Angeles, California. 
Refer to charted regulation section numbers. 

NOTE F
Submerged submarine operations are conducted at various times in the waters
contained on this chart. Proceed with caution.


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 Department of the Navy.


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


SUPPLEMENTAL INFORMATION 
Consult U.S. Coast Pilot 7 for important supplemental information.


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).


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


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 Imagery and Mapping Agency Publication 117.
Radio direction-finder bearings to commercial broadcasting stations are subject to 
error and should be used with caution.


CAUTION
Mariners are cautioned that exploratory surveys and exploratory drilling operations 
may be in progress in, or in the vicinity of, the Southern California Traffic Separation 
Scheme.  These operations may pose hazards to navigation.  The most recent 
Eleventh Coast Guard District Local Notice to Mariners should be consulted for 
the schedule of current operations.


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.


CABLE AND PIPELINE AREAS 
The cable and pipeline areas falling within the areas of the larger scale charts are shown 
thereon and are not repeated.


NOAA WEATHER RADIO BROADCASTS
The NOAA Weather Radio stations listed below provide continuous weather 
broadcasts. The reception range is typically 37 to 74 km / 20 to 40 nautical 
miles from the antenna site, but can be as much as 186 km / 100 nautical 
miles for stations at high elevations.

Los Angeles, CA 	KWO-37		162.550 MHz
Santa Ana, CA		WWG-21		162.450 MHz


MINERAL DEVELOPMENT STRUCTURES
Obstruction lights and sound (fog) signals are required for fixed mineral development 
structures, subject to approval by the District Commander, U.S. Coast Guard (33 CFR 67).


TIDAL INFORMATION
For tidal information see the NOS Tide Table publication or go to http:

ADDITIONAL INFORMATION
Additional information can be obtained at nauticalcharts.noaa.gov.

IMO AMENDED TRAFFIC SEPARATION SCHEME
Portions of the traffic separation scheme shown on this chart have been amended by the IMO. 
See IMO COLREG.2/Circ.64. Please be advised that these portions have not been revised by the 
United States Coast Guard and that the corresponding changes have not been updated in the 
Code of Federal Regulations (33 CFR part 167). There are differences between the two traffic 
separation schemes and caution is advised.
