[DATE OF SAMPLING UNKNOWN OR NOT APPLICABLE.] The formation resistivity factor, 
F, necessary to calculate bulk sediment diffusion coefficients of interstitial solutes 
from free solution diffusion coefficients, can be estimated from f, the sediment 
porosity. Empirical relationships between F and e 2 indicate that F - C‘ 2 for unlithified 
marine sands or muds when e 0.7 and F - c 2 - 5 to C‘ 3 for high porosity muds when e ^ 
0.7. Cores were collected from Captain Key Bank, Florida Bay, as well as from other 
locations.

[ABSTRACT ONLY. DATE OF SAMPLING UNKNOWN OR NOT APPLICABLE.] Intrusions of 
polar continental air into the south Florida/northern Bahama Banks region cause rapid 
and extensive chilling of shallow reef, associated bay and bank waters. 'Coral kills' 
observed during the 1969 - 1970, 1976 - 1977, and 1980 - 1981 winters were 
attributed to cold-water induced stress. Thermal evolution of Florida Bay and northern 
Bahama Banks waters was assessed for critical times during these winters with 
temperature-corrected thermal infrared data acquired by the NOAA-5 and NOAA-6 
environmental satellites, in-situ water temperatures, and a computerized heat-flux 
model. Laboratory and field experiments identify 16°C as a thermal stress threshold 
for most reef corals. Sub-16°C waters were generated in shallow bay and bank areas 
during January of each winter. Offshore movement of super chilled waters interrupted 
warmer conditions along bank margins, subjecting corals to stressful waters. Strong 
northerly winds are the primary initiator of this offbank flux; however, density 
gradients and tidal pumping may increase the transport rate. Absence of reef 
development opposite major tidal passes connecting Florida Bay and the reef tract, as 
well as coral moralities observed, is attributable to this process, which has probably 
limited Holocene reef growth in these areas.

[NO COPY OF PAPER AVAILABLE. ABSTRACT FROM SCHMIDT (1991).] This report 
provides a detailed description of the community structure and ecosystem process of 
the seagrass ecosystems of south Florida including Florida Bay, one of the two major 
areas of seagrass distribution in Florida. This description is based upon a compilation of 
information from numerous published and unpublished sources. The material covered 
includes distribution, systematics, physiology, and growth of the plants, as well as 
succession and community development. The role of seagrass ecosystems in providing 
both food and shelter for juveniles as well as foraging grounds for larger organisms is 
treated in detail. Emphasis is given to the functional role of seagrass communities in the 
overall coastal marine system. The final section considers the impacts of human 
development on seagrass ecosystems and their value to both man and the natural 
system. Because seagrass systems are fully submerged and less visibly obvious, 
recognition of their value as a natural resource has been slower than that of the 
emergent coastal communities. They must, however be treated as a valuable natural 
resource and preserved from further degradation.
