Underwater Communication 



The tower's underwater communi- 

 cations system facilitates joint operations 

 between scientists and divers. In addition 

 it is used during test or repair of instru- 

 ments associated with the tower. The 

 underwater system used at the tower is an 

 adaptation of commercial systems and is 

 now called "Towercom. " With the 

 Towercom, divers can communicate with 

 each other. Confirmation that the diver 

 has completed his mission and that the 

 equipment is in operation makes for 

 efficient use of the limited time a diver 

 may stay on the bottom. 



Communication equipment worn by the diver includes 

 a special mouthpiece with microphone, a magnetic 

 earphone, and a short length of cable attached to an 

 underwater plug. 



The diver connects phone plug into any station 

 located throughout the underwater portion of the 

 tower arrays.
