place seriously abraded aluminum plates; re- 

 move pieces of metal found between coil and 

 plates; and tigliten bolts. Retrieve the sparker 

 once each 24 hours, and inspect it for missing 

 and worn electrodes, loose bolts, and broken 

 frame. Replace missing and worn electrodes, 

 repair broken frame by welding, and tighten 

 bolts. 



Step 4. The hydrophone array need not be 

 retrieved during seismic profile operations un- 

 less signals are not being received. If the 10-foot 

 hydrophone array is damaged and its buoyant 

 fluid is lost, it can be patched and refilled with 

 transformer oil. If the 128-foot array is dam- 

 aged and loses its fluid, small holes can be taped 



to prevent further loss, but no attempt should 

 be made to add fluid. 



T-3 Securing Seismic Profiling Equip- 

 ment. — \Vlien the operation is completed, re- 

 trieve the sound source and the hydrophone 

 array. Rinse the sound source and the hydro- 

 phone array with fresh water. Store the hydro- 

 phone array on a reel where it will not be 

 exposed directly to the sun. 



T-4 Seismic Profiling Data. — Seismic pro- 

 filing strip cliarts, logbooks, and a smooth plot 

 of the ship's track should be returned to the 

 Oceanographic Office for analysis.
