Lee, C. C. (1969) The decomposition of organic matter in some shallow water, calcareous 
sediments of Little Blackwater Sound, Florida Bay. Ph.D. Dissertation, University of Miami, 
Miami, FL. 106 pp + appendix. 
Nine cores from Little Black Water Sound (LBWS), Florida Bay, were sectioned and 
analyzed for pH, Eh, moisture, carbonate carbon, TOC, lipid carbon, as well as free 
fatty acids and glyceride fatty acids. Surface sediments between 0 and 4 cm deep were 
collected for laboratory degradation studies over a ten-week interval and TOC, lipid 
carbon, glyceride fatty acids and free fatty acids were analyzed at the end of each 
incubation period. The results of these analyses were correlated with measurements of 
the corresponding environmental parameters observed within the sediments (e.g. 
sediment composition, particle size, depth of sediment layer, moisture content, pH and 
Eh). The results from laboratory incubated sediments were also correlated with total 
bacterial counts. LBWS sediments showed two distinct distributions of organic carbon; 
values varied between 0.5 and 1.4% in shelly muds and between 1.9 and 13% in peaty 
sections. Concentrations of organic carbon increased with sediment depth; minimal 
amounts occurred within surface sections. Absolute concentrations of lipids for shelly 
muds were generally below 600 ng lipid C g * 1 sediment dry weight, but this amount 
constituted upwards of 8% of the total organic-carbon fraction. The distribution of 
lipids for peats, on the other hand, contained between 600 ng to 2.7 mg lipid C g -1 
sediment dry weight. However, peat lipids accounted for only 3% of the TOC content. 
As for TOC, lipid carbon levels increased with sediment depth. Minimal amounts were 
also found within the surface layers. Free, normal-fatty acids and normal-fatty acids 
from hydrolyzed triglycerides with carbon chain lengths of C 1Q to C 2Q were tentatively 
identified. C 16 and C 18 acids were the dominant acids detected. Although C 16 acid levels 
decreased with sediment depth and C 18 acid concentrations increased with sediment 
depth, no consistent patterns of distribution for the other acids were observed. An 
inverse-relationship of C 16 to C 18 acids was apparent and suggested an inter¬ 
dependence of the two acids resulting from selective utilization and production of one or 
the other acid is suspected and discussed. Degradation studies of incubated surface 
sediments indicated that the processes of organic matter degradation were cyclic and 
microbial in nature. The cycle begins with initial breakdown of readily usable 
substrates, synthesis of secondary products with depletion of usable substrate and the 
adaptation of either the same organisms to new substrates and environmental 
conditions or the development of new organisms to cope with the new conditions, 
followed by continued organic substrate utilization. Sampling was done in 1966.
