The habitat fresh-water supply was stored in a 2,000-gallon tank at the 



surface support center. The fresh water was gravity-fed through a hose 



in the umbilical bundle to the habitat. Fresh water was trucked to the 

 tank and chlorinated after each refill. 



A small parts trailer adjacent to the fresh-water tank contained small 

 spare parts for some of the utilities equipment and instriimentation. 



The purge nitrogen for the habitat was stored in a 22,000 SCF tube trailer 

 at the surface support center. The nitrogen was used to equilibrate the 

 habitat atmosphere upon initial pressurization and remained on hand in 

 the event further adjustment of the nitrogen-oxygen ratio was required. 



Diesel fuel for the generators was stored in two 1,500-gallon tanks in a 

 vehicle turning area up-grade from the support center. Resupply of the 

 diesel fuel was normally carried out by pumping through a 700-foot run 

 of rubber hose up the stairwell to the tanks from vessel or barge-borne 

 fuel truck. The fuel was supplied to the generators by hand pump or 

 gravity feed. 



CAUSEWAY PIER 



The causeway pier consisted of three causeway sections supplied by the 

 Department of the NaAO'^, each measuring 90 by 15 feet, joined together 

 to form a pier, extending from the beach some 270 feet out into the bay. 

 The water depth at the terminal end was approximately 26 feet. The pier 

 served as the principal landing for all of the program small boats and the 

 shuttle boat and larger vessels bringing supplies and personnel from 

 St. Thomas. The pier was held by concrete moorings and anchors at the 

 terminal end and at mid-length. A graded ramp was maintained at the 

 shoreward end which was held in place by heavy lines attached to two 

 500-pound deadmen. The baralyme supply and the habitat spare parts were 

 stored in two semi-trailer vans parked on an old road spur between the 

 causeway pier and the main road between Lameshur Bay and Cruz Bay. 



BASE CAMP 



The base camp (Figure 13), which had been built a year earlier for the 

 TEKTITE I program, was used as the principal accommodation facility 

 during TEKTITE II. After the earlier program the camp was turned over 

 to the College of the Virgin Islands, which managed it during the course 

 of TEKTITE II. The camp was primitive, but quaint, consisting of 13 

 tropical huts with partial siding and screens , Several of the huts were 

 connected for use as a kitchen-dining area, office-dispensary, and other 

 special purpose uses. Toilet and shower huts were also available. 

 Electricity for the camp was tied into the local power company line and 

 proved to be fairly reliable. In cases of severe rains and storms, power 

 was interrupted and the camp switched to diesel generators. Potable 

 water was stored in two 10,000-gallon underwater tanks. Fresh water
