Zone of Sandy Key, Florida, Prior to Beach Restoration," Final Report, National 



Marine Fisheries Service, Panama City, Fla., 1974. 

 This report defines some of the major physical, chemical, and biological characteristics 

 of the nearshore zone of Sandy Key, Florida, prior to beach restoration. It also includes 

 results of a supplemental study on the effects of hydraulic dredging for emergency 

 restoration of Sunset Beach on Treasure Island, Florida. An extensive bibhography on the 

 physical, chemical, and biological characteristics of the nearshore zone is included.

Organisms," Chesapeake Biological Laboratory Reference No. 74-20, Final Report 



Natural Resources Institute, University of Maryland, College Park, Md., Mar. 1974, 



267 pp., NTIS AD No. AOll 372. 



A 3-year laboratory study identified the biological effects of (a) suspended mineral 



soUds similar in size to sediments Ukely to be found in, or added to, estuarine systems in 



concentrations typically found during flooding, dredging, and disposal of dredged material, 



and (b) natural sediments. Generally, bottom-dwelling fish species were most tolerant to 



suspended solids; filter feeders were most sensitive. Early Ufe stages were more sensitive to 



suspended solids than adults. Carbon assimilation by four species of phytoplankton was 



significantly reduced by the light attenuating properties of fine silicon dioxide suspensions. 



Ingestion of radioactive food cells by two species of calanoid copepods was significantly 



reduced during exposure to suspensions of fuller's earth, fine silicon dioxide, and natural 



Patuxent River silt.

Describes techniques developed for the propagation of Spartina alterniflora (smooth 



cordgrass) in the intertidal zone of dredge spoil and eroding shorelines. Both seeding and 



transplanting methods were successful. The relationship of mineral nutrition to productivity 



of S. alterniflora was also determined.
