Rodriguez Bank and described for Florida Bay islands. A decrease in the rate of sea 
level rise about 3000 BP probably caused local changes from transgression to 
regression. The presence of basal transgressive peat, common to all bay-side deltas 
and under Florida Bay islands, Hawk Channel banks and ocean-side deltas indicates its 
early burial history and permanence of overlying sediments. Four conceptual models of 
tidal delta genesis were developed that usefully: (1) describe the feedback of dominant 
tidal delta processes and parameters; (2) relate delta size changes to competition 
between the rates of sedimentation and sea level rise; (3) place Tavernier delta in an 
earlier stage and Matecumbe delta in a later stage of ontogenetic development, with 
Snake Creek and Whale Harbor in intermediate stages; and (4) extrapolate the 
sedimentary history from rising sea level to falling sea level. An index of restriction, 
FM/AC ratio, was formulated to compare grain constituents at Snake Creek to adjacent 
areas. It appears to have wide application for regional carbonate facies studies. It is 
calculated as: 
FM/AC = 
% Benthic foraminifera + % Mollusks 
% Algae + % Coral 
Using the data of Gindburg and others, regional FM/AC values varied from very low 
(< 0.4) for the outer Florida reef track, to very high (> 50) for Florida Bay, with 
intermediate FM/AC values between.

Florida, a summary report. Geol. Surv. Prof. Pap. 1011. 81 pp. 
[NO COPY OF PAPER AVAILABLE. ABSTRACT FROM SCHMIDT (1991).] This report 
summarizes the scientific information database collected on the south Florida 
environment as a result of a variety of governmental (NPS, USGS, EPA, BSF&W, 
NMFS, BOR, etc.) and private (University of Florida) studies undertaken during the 
early 1970's to determine the effects of a proposed international jetport on the 
ecosystem of the Everglades National Park. This report concludes phase one of the 
phase two project, South Florida Environmental Study, which described and identified 
the natural ecosystems of south Florida as they functioned before man began to have 
major impacts on these systems. The study also encompassed the agricultural and 
urban developments of south Florida and their impacts on the ecosystems. Topics 
covered as they pertain to the coastal and estuarine environments of the Park include: 
mangroves and salt marshes, shallow estuaries and bays, marine fisheries, water 
quality and pesticide effects. The authors conclude that by developing a thorough 
knowledge of the south Florida environmental system and the flow of energy through 
that system, planning and development can occur and permit full use and enjoyment of 
south Florida's natural resources without destroying those resources.
