10 ft, and. the strength of current as tidal {8hQ ft per hr at half ehh 

 tide surface flow). The monthly records of temperatures and salinities 

 are given in the tahles which follow. In regard to pollution, it was 

 stated that there was very little surface oil; that there was waste from 

 "berthed naval vessels at this ajad adjacent piers; that the pier at which 

 this test hoard was installed was ahout 500 ft (east) from the loading 

 pier for deep-sea fishing hoats. On March 15, 19^6, the following con- 

 ditions were reported: "Mayflower with crew of 10i^ men herthed on west 

 side of pier; sanitary from Mayflower goes overheard; garhage on shore; 

 oil slick on surface confined more or less hy vessels herthed on either 

 side." 



5. Test Board No. 3 , The depth of water where this test hoard 

 was installed was 15 ft from mean low water to the mud line, so that 

 panel C was 10 ft helow mean low water. The range of tide was given as 

 10 ft, and the strength of current as tidal hut, hecause of permanent 

 and semipermanent her thing of various types of vessels, it was not 

 possihle to give the rate of flow under such changeahle conditions. The 

 mcaathly records of temperatures and salinities are presented in the 

 tahles which follow. Regarding pollution, it was stated that there was 

 very little surface oil, and that there was waste from herthed naval 

 vessels at this and adjacent piers. On March 15, 19^6, it was reported: 

 "Small craft tied up here, off and on; sanitary and garhage ashore; oil 

 slick at site of test hoard, slight amount inhoard." 



k. Test Board Ho. k . The depth of water at which this test hoard 

 was installed was 20 ft from mean low water to the m u d line, so that 

 panel C was ik ft helow mean low water. The range of tide was given as 

 10 ft and the strength of current as tidal (approximately 1000 ft per 

 hour). However, hecause of the nature of herthing of vessels, as at the 

 other locations of test hoards, it was impossihle to ohtain more than an 

 approximation of the current strength. The monthly records of tempera- 

 tures and salinities are presented in the following tahles. Sources of 

 pollution at this site were given as the sanitary disposal overhoard from 

 the crews of USS Falcon, "n) Ko. 6l, 75, and other nearhy herthing areas. 

 It also was reported that there was an oil slick on the surface, and 

 that newly driven fender piles were coated with oil. 



5. Water Temperature . The following record of the temperature of 

 the water in degrees F, hased on readings made ahout the middle of each 

 month and taken at panel C on each test hoard, shows the range at each 

 location.
