PROCUREMENT An AEC furnished 7 x 17-ft. Model 16 Northwest camper trailer, for use at the Canton Tamarin site, Hawali. is on standby at Damon Tract, Oahu, POST-GO CONSTRUCTION The AEC furnished Type II Wave Sensor equipped installation is to be located at an undetermined off-shore location in the vicinity of Canton Island. The primary objective of this scientific site 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. The auxiliary equipment will also be installed in the AEC camper trailer by DRL personnel. This installation will contain a differential sensor and data logging system. An armored cable connects the implanted wave sensing transducer and the com- pletely self-contained datalogging system. The transducer and sensor will be in- stalled by DRL scuba divers in approximately 30 to 50-ft. of water, located ina position to eliminate as much shore-induced phenomena as possible. Voice communications to Damon Tract will be provided by the U. S. Army Communications Center (F&S No. 21014). DRL personnel will assemble at Damon Tract to prepare equipment prior to deployment. A DRL Type Il installation team of + persons including scuba divers and technical personnel will emplace and roll up equipment; one man will operate and maintain the equipment for the duration of the program. DRL personnel will obtain subsistence in the camp facilities (F&S No. 21010). For a summation of Tamarin installations see F&S No. 05027. 2l-y eae VOL II April 1969
