vessels. Circulation patterns were determined. Chemical analyses of water samples were 

 made; sediment and biological samples were analyzed. Included are studies of marine Ufe, 

 bacteria, and waste disposal. Impacts on ecology and water quality are discussed.

A Review," MP 1-73, U.S. Army, Corps of Engineers, Coastal Engineering Research 

 Center, Washington, D.C., Jan. 1973, NTIS AD No. 756 366. 



A review of ecological effects of offshore dredging is presented. Although basic 

 ecological works are available, there has been little concrete effort to determine effects of 

 offshore dredging; additional research is needed to approach fuU understanding. Report 

 shows that a beach may be divided into three zones on the basis of moisture and biota, and 

 describes the possible effects on these biota from offshore dredging and deposition of 

 sediments. Background material and impacts on botli offshore dredged areas and nourished 

 beaches, and suggestions for further research are included. A selected bibliography is 

 included.

Ecological monitoring of algae, invertebrates, and fishes was conducted along the 

 southeast Florida coast in connection with offshore dredging and beach nourishment 

 projects. One area surveyed showed no adverse ecological effects; reef damage by dredging 

 equipment was found in another area. Ecological data have been recorded for three other 

 areas proposed for dredge-and-fiU operations.

 Mar. 1974, NTIS AD No. 777 764. 



This is a glossary of basic ecology terms commonly encountered in the field of coastal 

 engineering. The terms are apphcable to, but not necessarily restricted to, marine and 

 freshwater environments of the coastal zone. Terms are cross-referenced and defined in 

 nontechnical language for use by nonecologists.

Rincon Island is a manmade offshore island composed of armor rock and tetrapod 

 revetments enclosing a sand core. An evaluation after 14 years shows: no damage by waves; 

 httoral transport has been unaffected; Uttle subsidence has occurred; and a thriving 

 community of marine organisms has developed.
