days following implantment. The corrosive link 
was supposed to release the nylon after four 
days but either never completely released or the 
line became entangled. The nylon line was then 
weighted and allowed to sink. The array went 
from 20° tilt to less than three degrees during 
this operation as the line sank and the hydrody- 
namic drag forces were reduced. 
The unit was accepted with a demonstration 
of it's performance and data collection was 
started. 
CONCLUSIONS 
A fairly complex electronic-acoustic device 
can be successfully designed and installed ina 
deep ocean environment.
