recovery of the array wlien EVERGREEN was 

 ready. During interrogation of the acoustic re- 

 lease, it was necessary to turn off the ship's 

 fathometer (UQN^) so that the fathometer 

 signal would not be received by the release re- 

 ceiver and mask the pinger signal. 



When the EVERGREEN was in position near 

 the surface float, the acoustic release was fired, 

 thereby freeing the array from the anchor. The 

 surface float was then lifted onto the buoy deck 

 with the whip, and the chain below the fixed 

 bridle was secured in the chain stopper (Figure 

 11). The chain below the bridle was then cut 

 with an acetylene torcli (Figure 12), and the buoy 

 was secured on deck. The remaining chain was 

 brought aboard with the boom, and the remainder 

 of the array was pulled in by hand (Figure 

 13). When the entire array was on deck, it was 

 disassembled. The current meters were secured, 

 and all instruments were rinsed in fresh water 

 and stowed.
