environment. For this purpose we envision a boat of 

 approximately 40 meters, with an Albacore -type hull, 

 a sail, a subnnerged speed of 20 knots, and capable of 

 dives of at least 8 to 10 hours at full speed for a large 

 part of the diving time. The ability to operate more or 

 less continuously underwater would greatly increase 

 the usefulness of such a vessel. It would have viewing 

 ports, water and plankton sampling devices, television, 

 several kinds of acoustical gear, a suit of modular 

 sensors with readouts onboard, and remote manipu- 

 lators. A converted Navy submarine would not be suita- 

 ble. 



1.23Z0 Small, Manned, Pressure Resistant Vehicle. .... (10) 

 There is also need for a much smaller vehicle for two 

 or three men, which could operate from a mother ship. 



1.2330 Drone (8) 



An instrumented surface or subsurface vessel which 

 could either be programmed to a search pattern or 

 commanded from a mother ship or shore, to operate 

 at depths of up to 500 m. 



1. 3000 SAMPLING DEVICES . 



1. 3100 WATER. 



1.3110 Micro Water -sampler (26) 



Purpose: A device for obtaining a small water sample 



from a thin stratum. 

 Specifications and requirements: 



(1) Capacity: 10 to 50 ml. 



(2) Filling time less than 10 sec. 



(3) Must sample a stratum of 2 cm. or less without 

 drawing in water from strata above or below that 

 being sampled. , 



(4) Positioning of this sampler above the bottom to 

 within ±2 cm. is necessary. 



1.3200 PLANKTON. 



1.3210 Low Speed Plankton Sampler Frame (75) 



Purpose: To provide opening and closing capability and 

 environment sensor carriage for standard 1 -meter, 

 1/2-meter, and other conventional plankton nets.
