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 tlie 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 bibliography on the 

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

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

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 soUds; filter feeders were most sensitive. Early hfe stages were more sensitive to 

 suspended sohds 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 (smootli 

 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.
