TO BE DETERMINED PRIOR YEARS ENGINEERING None required. PROCUREMENT An AEC furnished 7 x 17-ft. Model 16 Northwest camper trailer, for use at the Palmyra Tamarin site, is on standby at DamonTract, Oahu, Hawaii. POST -GO CONSTRUCTION The AEC furnished Type II Wave Sensor equipped installionis to be located at an undetermined off-shore location in the vicinity of Palmyra 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 predeter- mined 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 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. Voice communications to Damon Tract will be proviued by the U. S. Army Communications Center (F&S No. 25011). DRL personnel will assemble at Damon Tract to prepare equipment prior to weployment. A DRL Type II installation team of 5 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 at the camp facilities (F&S No. 25007). For a summation of Tamarin installations see F&S No. 05027. 25-9 VOL II April 1969
