pear in the actual array. A check-off list was 

 completed for each instrument in the array to 

 insure that it was ready to be set. A single 

 inner tube was lashed to each instrument in the 

 array to provide flotation while the array was 

 being set and recovered. The lines used to secure 



the flotation to the instrument were passed be- 

 tween the tie rods and the pressure case to pre- 

 vent the inner tube from slipping ofi^ as it was 

 compressed by water pressure (Figure 8). After 

 a final check to make sure that everything was 

 assembled properly, the array was neatly laid
