PROCUREMENT
Two (2) AEC furnished 7 x 17-ft. Model 16 Northwest camper
trailers, for use at the Johnston Atoll Tamarin sites (see F&S No.
05007), are
on standby at Damon Tract, Oahu, Hawaii.
POST-GO
CONSTRUCTION The AEC furnished Type II wave sensor equipped installations
are to be located on the perimeter of Johnston Atoll. The primary objective of
these scientific sites is to measure and record for Tsunami studies the amplitude and time of arrival of long period waves over a predetermined period. The
underwater equipment will be emplaced by Defense Research Laboratory (DRL)
personnel at two undetermined offshore locations on JA. The auxiliary equipment
will also be installed by DRL personnel in the two AEC camper trailers.
Each of the two installations will contain a differential sensor, data logging
system, and an armored cable connecting the implanted wave sensing trans-
ducer with the completely self-contained data logging system.
The transducer
and sensor will be installed by DRL scuba divers in approximately 30 to 50-ft.
of water, located in a position to eliminate as much shore-induced phenomena
as possible,
DRL personnel will assemble at Damon Tract to prepare equipment prior to
deployment. A DRL Type II installation team of 6 persons, including scuba
divers and technical personnel, will emplace and roll up equipment; 1 man
will operate and maintain the equipment for the duration of the program.
