circulation pattern; wind and waves respond to seasonal changes in circulation 
patterns. Effects of hurricanes, tropical storms, and winter cold fronts are also 
discussed. Sections discussed as they pertain to the Everglades region include 
extensive chemical data on nearshore and estuarine waters including water quality, 
nutrients, minor elements and their hydrology are presented. A discussion of the 
biological environment is presented relative to both the environment and organism 
including salt marshes, mangroves, seagrass beds, plankton, major benthic 
invertebrate groups, fishes, marine mammals and birds. The Ten Thousand Islands - 
Florida Bay area is considered as one of the most complex coastal areas in the United 
States.

[DATE OF SAMPLING UNKNOWN OR NOT APPLICABLE.] All available information and data 
concerning geology, geological history and development, and geological processes of the 
subject areas were gathered, evaluated and reduced, whenever possible, to a format 
appropriate for computer storage and retrieval. The information and data topics 
included ground water, tides, currents, waves, hydrography, shoreline erosion and 
accretion, and shallow water structure and stratography. An annotated bibliography 
was prepared. Aerial photographs (USGS, US C&GS/ESSA/NOAA and other sources), 
maps and charts and foundation borings and other engineering data were catalogued. 
Despite delays in obtaining equipment, maps, charts and air photos and developing the 
capability of time-lapse motion picture photography, the objectives were reasonably 
accomplished. The collation of existing information is essentially completed except for 
keeping up with current publications. Site visits by all the project personnel have 
provided a good insight and working knowledge of the geology and physical condition, in 
the subject areas and the basic processes that affect these areas. Because of a 
prolonged but apparently unavoidable delay in receiving the smooth sheets and 
topographic charts for NOAA, work on the historical trends of shoreline change and, 
hence, the forecast of future trends is still underway. Along with the time-lapse 
photography this important study will be given first priority in the proposed 
continuation of the project.

[NO COPY OF PAPER AVAILABLE. ABSTRACT FROM SCHMIDT (1991).] A study on the 
effects of upstream environmental conditions on the epibenthic community structure in 
the Whitewater Bay - Shark River estuary was conducted during 1973 - 1974. It was 
found that runoff, as it affected water levels in the water shed and the reduction of 
annual rainfall and increase in saltwater intrusion from Florida Bay, determined the 
seasonality and magnitude of salinity flux in the estuary, resulting in the replacement 
of the estuarine nursery area by a coastal marine system. The authors suggest that 
although the system will remain productive, its loss will cause reduction of fisheries as 
supported by larval recruitment. Salinity and substrate significantly affected the 
amount of total benthic biomass. Authors suggest salinity most important since 
substrate does not change seasonally.
