feet) wide, extends from behind the dune line to about the 6-meter depth con- 

 tour, and is 7.7 meters (25.4 feet) above mean sea level (MSL). One set of 

 railroad rails, 3.1 meters (10 feet) apart and extending from the garage of 

 the laboratory building to the end of the pier, is used to transport heavy 

 loads. Instrumentation cables run the length of the pier in a trough along 

 the north side of the deck. Outlet boxes for both 220 and 115 volt power are 

 located at 12-meter (40 feet) intervals along the south side. Removable grat- 

 ings in the pier deck can be used for lowering instrumentation. There are two 

 telephones on the pier — one at the end and one midway. 



Locations on the pier are referenced by distance in feet from a monumented 

 base line located landward of the laboratory and perpendicular to the pier 

 centerline; e.g., the end of the pier is at station 19+40 (see Fig. 5) and the 

 midpier telephone is at station 10+80. 



Five steel piles (o.d. 6-5/8 inches) suitable for mounting instrumentation 

 are located midway between the piles at stations 7+00, 7+80, 9+00, 10+60, and 

 14+20. These piles extend from the pier deck to the sea bottom. 



The laboratory building includes offices, a kitchen, a library, a computer 

 center, a garage, and a diving locker. The computer center (Fig. 7) houses a 

 Data General NOVA-4 minicomputer. An emergency generator provides backup 

 power for lighting and data collection equipment. The roof of the building 

 provides a flat observation deck with an elevation of 12.4 meters (40.8 feet) 

 above MSL.
