AIDS TO NAVIGATION
Consult U.S. Coast Guard Light List for
supplemental information concerning aids to 
navigation.
See National Geospatial-Intelligence Agency 
Center List of Lights and Fog Signals for informa-
tion not included in the U.S. Coast Guard Light 
List.


SUPPLEMENTAL INFORMATION
Consult U.S. Coast Pilot 9 and National 
Geospatial-Intelligence Agency Pub. 152 for im-
portant supplemental information.


CAUTION - SIGNIFICANT CHANGES
Significant changes in depths and shoreline may have occurred
in the area of this chart as a result of the earthquake of 
March 27, 1964. Tidal observations since the earthquake indicate 
bottom uplift of +0.09 meters / +0.3 feet at King Cove, Alaska 
Peninsula and bottom subsidence of -0.06 meters / -0.2 feet of 
Chignick Bay, Alaska Peninsula. Observations at Sand Point, Popof 
Island, indicated there was no change at that location. Mariners are 
urged to use extreme caution when navigating in the area of this chart 
as the magnitude of change except at these sites is not known.


NOTE A
Navigation regulations are published in
Chapter 2, U.S. Coast Pilot 9.  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.


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


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 com-
munication is impossible (33 CFR 153).


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.


NOAA WEATHER RADIO BROADCASTS
The NOAA Weather Radio station 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.

Survey with additional data from the National Geospatial-Intelligence
Agency, Corps of Engineers, and U.S. Coast Guard.


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.


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.
