The behavioral observers recorded pertinent data on the aquanauts via 

 closed-circuit television monitors and audio equipment located in the 

 behavioral sections of the command van. (See section on Human Behavior 

 Program. ) 



The support divers were in a constant state of readiness on the dive 

 platform. During each excursion from the habitat by the aquanauts, two 

 support divers manned an outboard powered rubber boat, equipped with 

 scuba gear for the support divers and emergency scuba gear for the 

 aquanauts. The support boat was normally positioned over the aquanaut 

 work area and upon receiving any one of three emergency signals, the sup- 

 port divers were instructed to dive down to the aquanauts carrying spare 

 scuba gear. 



Two support divers were stationed on the decompression barge when 

 aquanauts were outside the habitat, ready to operate the PTC/DDC system 

 in an emergency. Between aquanaut excursions, the support divers main- 

 tained the decompression complex and carried out drills simulating the 

 various emergency conditions. The drills were conducted by the diving 

 supervisor under both scheduled and unannounced conditions. 



The operations director or designated director was on-site during each 

 watch period. He coordinated all site activities, determined that support 

 facilities were in a constant state of readiness, and in emergency con- 

 ditions assumed full command. 



The safety officer made frequent inspections of the facilities, observed 

 emergency drills and routine operations, and advised the operations 

 director and program manager of safety considerations or problems. 



A medical officer, on call at the operational site, served as the phy- 

 sician for all support personnel, assured that health standards were main- 

 tained in food preparation and potable water supplies. He made daily 

 observations on the medical status of the aquanauts. The medical officer 

 was responsible for both normal and emergency decompression events. 



The diving supervisor was responsible for the diving training and checkout 

 of all support divers and aquanauts. He enforced diving regulations at 

 the operational site and was responsible for underwater tasks related to 

 the operation. 



The utilities technician maintained the generators and related equipment 

 insuring that adequate supplies of fuel and lubricants were on hand. He 

 performed repairs and upkeep on support boats and vehicles and life 

 support utilities at the surface support center. 



In the event of an emergency, the behavioral observers were to report to 

 the watch director for assignment to the communications console, the decom- 

 pression barge, or as additional support divers, since all were qualified 

 divers .
