permanent stations for more than one year in Whitewater Bay, Coot Bay and in Florida 
Bay adjacent to Flamingo on the north coast and Plantation Key on the south coast to 
evaluate the variability in composition and abundance of fish among mangrove areas. 
Block nets and rotenone were used to sample the intertidal fringing habitat, and two- 
boat otter trawls were employed to sample the adjacent seagrass areas to compare 
species composition. Stomach contents of some fish species from both habitats also 
were evaluated. In addition, such structural characteristics as prop root and seagrass 
density and sediment particle size and organic content were measured. Our data 
indicate that fringing red mangrove prop root habitats in Everglades National Park are 
utilized by juvenile and adult fish.

[DATE OF SAMPLING UNKNOWN OR NOT APPLICABLE.] In cooperation with the National 
Park Service, the Southeast Fisheries Center, Beaufort Laboratory initiated a research 
program to examine habitat utilization during the early life history of four species of 
fish (red drum, Sciaenops ocellatus ; spotted seatrout, Cynoscion nebulosus ; snook, 
Centropomus undecimas; and mangrove snapper, Lutjanius griseus) that are important 
to the sport fishery in the Everglades National Park. The long-term goal of this 
research is for ENP to understand the causes of variation in abundance and distribution 
of these fishes. The emphasis is on life history stages, habitats, ecological processes 
and environmental factors that are believed to be related to abundance. Specific 
objectives are to: (1) determine the relative abundance timing and location where 
larval fishes enter the Park and (2) evaluate the relative abundance and composition of 
juvenile fish communities among habitat in the Park and develop descriptions of habitats 
in which fish occur. Major habitats being examined are (1) coastal spawning areas, (2) 
migration routes, (3) seagrass meadows, and (4) intertidal mangroves.

Ten cores from Florida Bay reveal new information concerning Pleistocene sedimentary 
units deposited in South Florida. Using R. D. Perkins ’Q-unit" classification proposed in 
1977, four units (Q1 through Q4) were recognized. A Q5 unit was not observed. Units 
older than Pleistocene were penetrated in several cores. Contoured maps show several 
paleotopographic features that influenced Pleistocene sedimentation. The Cape Sable and 
South Florida Highs were draped with elastics eroded from the mainland. The 
Pleistocene shelf edge and an open marine-platform are also discernible. Q2 time 
marked a switch from clastic sedimentation to in situ carbonate production. In Q3 time 
a barrier reef began growing at the Pleistocene shelf edge, with patch reefs growing in 
the back-reef area. A peloidal unit, the bryozoan facies of the Miami Limestone, was 
deposited in the lagoonal back-reef area during Q4 time. This deposit comprises the 
upmost Pleistocene bedrock immediately underlying Florida Bay. The cores were taken 
from Ninemile Bank, Twin Key, Russell Key, Park Key, Nest Key, Black Betsy Key, 
Crane Key, East Key, Cotton Key and Windley Key.
