PROCUREMENT An AEC furnished 8 x 8 x 10-ft. transportainer stocked with
Type I equipment and spare parts is located at Defense Research Laboratory
(DRL), Santa Barbara, California.
POST-GO
PROCUREMENT
To be accomplished.
CONSTRUCTION The AEC furnished Type I wave sensor equipped installations
are to be located over a wide geographic area of the Pacific Ocean. The primary objective is to measure and record the amplitude and time of arrival of
long period waves over a predetermined period and to coordinate this data with
that collected at Type Il and TypelIII Tamarin sites.
The equipment will be
emplaced, after initial surveys by DRL personnel, at three deep ocean Sites
between JA, Palmyra, Canton and Wake.
The Type I recording instruments
will be put afloat in a small surface follower buoy, which replaces the skiff
formerly used at Type sites.
The three Type I systems will be replaced with a new system as funds become
_available. The present system includes a taut wire instrument buoy system
that is moored in deep ocean. The submerged instrumented buoy is connected
to electrical conductors within a polypropylene line to a surface follower buoy
that contains the recorders, batteries, and necessary timing devices. Each
installation contains a differential sensor, data logging system, and an ar-
mored cable connecting the implanted wave sensing transducer with the completely self-contained data logging system. All devices will be installed by
DRL personnel from aU. S. Navy ATF vessel that is to be outfitted and
partially loaded in the Pearl Harbor Naval Shipyard. The remainder of the
equipment will be loaded at Johnston Atoll.
