I.n. OCEANOGRAPHIC RADIOACTIVE WATER SAMPLER 



Primary Use: 



To be utilized on oceanographic survey ships for the purpose of 

 collecting sea water samples in order to trace and investigate radio- 

 activity background and anomalies. 



Requirements and Specifications: 



a. To be utilized when the ship is stopped ( "lying-to"). 



b. The sampler and associated gear to be constructed of non- 

 contaminating material. 



c. The sampler to contain a plastic liner of about 15 gallon 

 capacity. 



d. The sampler must be of a non-contaminating type which can 

 be opened and closed at any desired depth by remote operation from 

 shipboard. This may or may not require the need for the sampler to 

 withstand hydrostatic pressure. 



e. To be designed so that one to two men can conduct the sampling 

 operation, utilizing standard hydrographic wire and equipment. 



f. To be designed to permit operation in multiples of four or more 

 samplers per cast.
