summer. These changes are attributed to various causes chief among them being wind 
direction, nutrient supply, rainfall, water circulation, and basin configuration. 
Geochemical analysis indicated that the waters of Florida bay are supersaturated with 
respect to calcium carbonate. Inorganic precipitation of calcium carbonate can occur in 
certain regions of the Bay, particularly in the Northern subenvironment. X-ray 
diffraction studies indicate no evidence for diagenesis in the mineralogy of the 
sediments from Florida Bay. Forty one stations were sampled during 1984.

[DATE OF SAMPLING UNKNOWN OR NOT APPLICABLE.) The coastal estuaries are among 
the most threatened natural environments in Florida. They exist where freshwater 
runoff from the uplands, streams and rivers meets the sea and are under continual 
threat from land development, pollution and dredge and fill activities, as well as 
commercial and recreational overuse. Florida’s estuaries are similar in structure to 
estuaries throughout the world. However due to location and climate, they support 
biological communities that are unique within the continental United States. These 
estuaries were formed through combined forces of reef building, land subsidence, 
sedimentation, periodic storms and a gradual rise in sea level during the last 4000 to 
6000 yrs. Man's activities during the last century have resulted in five major types of 
adverse impacts: (1) changes in natural watershed characteristics have severely 
altered inflow of freshwater, nutrients and sediments; (2) structural changes have 
occurred to stabilize inlets, create and maintain channels and modify shorelines; (3) the 
timing and quantity of freshwater inflow have been altered; (4) water quality has been 
degraded through the introduction of excessive nutrients and pollutants; and (5) benthic 
and shoreline communities have been destroyed or extensively damaged. Twelve major 
estuarine areas of South Florida are identified. A physical description, summary of 
research, discussion of problems, and survey of current management studies are 
presented for each estuary. A list of references for the region and for each estuary is 
provided as a guide to the literature. These studies and the level of current interest 
indicate that major efforts are underway to analyze and resolve the problems of South 
Florida's estuaries. The result will be a substantial increase in knowledge and our 
ability to manage these systems.

[ABSTRACT ONLY.) Studies to determine movement of spotted seatrout, Cynoscion 
nebulosus, red drum, Sciaenops ocellatus, gray snapper, Lutjanus griseus, black drum, 
Poganias cromis, sheepshead, Archosargus probatocephalus, were conducted in Florida 
Bay and along the west coast of Everglades National Park. A total of 3,237 fish of the 
five species were tagged from March 1984 to March 1985; 1,797 individuals from 
Florida Bay, and 1,440 individuals from the west coast were tagged. Spotted seatrout 
moved less than 6 km from point of tagging and had return rates of 3 and 1.6% for the
