Some swell can occur as a result of persistent northeasterly winds 

 and a considerable amount may be refracted around Clifton Point on 

 the western end of New Providence Island into the TOTO. 



FRESH CREEK (SITE 1) 



Site 1 is two miles south of the entrance to Fresh Creek on 

 Andros Island. No specific bearing was followed during the Site 1 

 survey. Instead, the entire area delineated in Figure 5 was 

 reconnoitered and representative bottom photographs were taken. 

 Survey efforts concentrated on the barrier reef and outer platform 

 where divers were towed underwater on plane boards normal to the 

 reef along tracks positioned with Decca. 



The backshore area consists of a sand dune 3 to 4 feet high 

 covered by low shrubs and bushes which terminate sharply at the 

 beach face (Plate 1). The beach consists of a medium-grained, 

 calcareous sand sloping gently seaward. The first several hundred 

 yards into the lagoon a clean, sandy bottom is present; proceeding 

 toward the reef the sand thickness decreases and overlies the 

 extension of Andros country rock into the lagoon. The lagoon 

 bottom supports a thinly populated community of various marine 

 organisms. In places where the bottom has little or no sand 

 veneer the organisms have concentrated to form a local topo- 

 graphic high 3 to 5 feet above the general lagoon depth of
