I SPECIAL NOTICES

ALASKA - JUNEAU - SEASONAL AIDS TO BE COMMISSIONED

During the week of 07 Apr 96, the Mendenhall Bar Channel Buoys (LLNR
23735) will be commissioned for the season.

ALASKA - DGPS

The Coast Guard DGPS service has been declared operational for
navigation. During this Initial Operational Capability (IOC) Phase,
users continue to be cautioned to use all available navigational tools
to ensure proper evaluation of position solutions. Problems identified
in the pre-operational phase are being resolved. Full Operational
Capability (FOC) of the DGPS service is anticipated when all operational
and support performance requirements are met. The seven Differential GPS
beacons listed below have been established to serve Alaskan waters.
These Differential GPS beacons have been modulated with a correction
signal, which is used to improve the accuracy of GPS. Aviation users are
cautioned that DGPS corrections degrade performance of some automatic
direction finders used in aviation applications. For users on the
Pacific Coast encountering problems with DGPS or needing more
information, please call the Coast Guard Navigation Center, Western
Operations Branch at (707) 765-7612/7613.

ALASKA - SOUTHEAST - KEKU STRAIT AIDS TO NAVIGATION

The Coast Guard is establishing an aids to navigation system in Keku
Strait. Mariners are reminded the project is approximately 50% complete
with aids in place from the vicinity of Entrance Island to the north
entrance of The Summit. This project should be completed in September
1996.

ALASKA - KODIAK ISLAND - KODIAK HARBOR - BREAKWATER CONSTRUCTION

Aqua-Marine Constructors, Inc. is constructing the new breakwaters for

A chart number preceded by an asterisk (\*) indicates that it is the
largest scale chart on which the correction appears. The word (Temp)
below the chart

number indicates that the chart correction action is temporary in
nature.

The letter (M) immediately following the chart number indicates that the
correction should be applied to the metric side of the chart only, and
is not part

of the chart number.

Courses and bearings are given in degrees clockwise from 000² to 359²
true as observed from a vessel to the light. The nominal range of lights
is expressed in nautical miles (M).

Positions given for chart corrections will be in the datum referenced by
the current edition for that chart.
