AIR-SEA SURFACE INTERFACE ENVIRONMENTAL DATA RECORDING SYSTEM 
Sketches 
(To be provided) 
Primary User 
To be utilized by oceanographic survey ship primarily for underway 
Operations, and secondarily for stopped operations, to sample and 
record the key environmental data found at and/or near the air-sea 
interface. 
Requirements and Specifications: 
ae To be designed and constructed primarily for underway operations 
at ship's speeds of 0-15 knots. 
b. A strict requirement is that the sensors be designed and located 
so as to measure the environment immediately at the interface or as close 
thereto as possible, without being adversly affected by own ship's motion 
and air turbulence over the ship projections as the ship moves through 
the water.
