rived from a combination of factors in-, 

 volving geologic characteristics of the 

 area, location of the laboratory, storm ef- 

 fects peculiar to Sanely Hook Bay, the 

 small amount of funds available, and the 



anticipated requirements of our experi- 

 mental a(|uarium. 



The Sandy ITook ^Marine Laboratory is 

 located 160 feet east of the easterly shore 

 of Sandy Hook Bay (fig. 1). The Sandy

Hook peninsula is a post-Pleistocene de- 

 velopment that resulted from deposition 

 of sand and gravel by northerly long-shore 

 currents which are interrupted by the out- 

 flow from New York Harbor and Raritan 

 and Sandy Hook Bays. The average 

 depth of waters surrounding Sandy Hook 

 is about 20 feet. This permeable sand and 

 gravel deposit hydraulically connected to 

 the bay appeared to provide an excellent 

 source of good quality sea water. A well 

 supplying a continuous flow system could 

 be located at the edge of the Bay near the 

 source of the water and yet be only a short 

 distance from the Laboratory. The plan 

 consisted of the following : 



1. A 4-incli-diameter poly vinyl-chloride (PVC) 

 wellpipe fitted with a 4-foot-long PVC slotted 

 intake screen (slots 0.014 inch in width) was to 

 be inserted into a G-inch-diameter (driven) iron 

 housing and water-jetted to the minimum depth 

 necessary to obtain sea water of full bay-strength 

 salinity. 



2. A nonmetallic submersible pump capable of 

 a minimum pumping capacity of 20 gallons per 

 minute was to be inserted into the 4-inch PVC 

 pipe to maintain a continuous flow of sea water 

 to the aquarium. 



3. A 114 -inch-diameter PVC transmission line 

 to carry the water underground to the basement 

 laboratory was to be riin inside a 6-inch-diameter 

 cast-iron housing. 



4. A 3-inch-diameter PVC gravity-flow return 

 line was to be run within the 6-inch iron pipe, 

 the iron pipe to serve as protection for the re-
