(2) Precision depth/graphic recorder for utilization with 
AN/UQN Sonic Sounding Set. 
(3) One electronic bathythermograph with associated winch-wire- 
boom-recorder/readout assembly. 
(4) An automatic recording sea-surface temperature probe. 
(5) A suit-case size meteorological instrument to record auto- 
matically key air-sea interface meteorological data, including total in- 
cident and reflected solar radiation. 
(6) Towed magnetometer with an all-weather capability. 
(7) An "interim" wave height measuring/recording device. 
In the design and fabrication of this "instrument suit", consideration 
shall be given to two different applications: (1) installing all of the 
above in a small "van" for trans-shipment to and on-deck stowage on the 
particular ship or (2) integrating certain of the above components into 
abready-existing "instrument suits" of certain ships such as destroyers, 
etc.
