province to the west. In the northern part of Florida Bay, water flow is greatly 
impeded by a complex bank and base system, and the clay mineral suites remain 
relatively segregated near their respective sources. However, in the southern part of 
the Bay, banks are less frequent, water flow is less impeded, and the clay mineral 
suites mix gradually across the area.

[DATE OF SAMPLING UNKNOWN OR NOT APPLICABLE.] Carbonate sediments, 
representing various depositional environments from the Florida Coast, Keys, and Bay 
area, were analyzed by x-ray, infrared, and atomic absorption methods. Aragonite and 
high-magnesium calcite were found to be the dominant minerals formed in shallow 
water environments, whereas calcite was the predominant mineral phase in deep sea 
carbonate sediments. Spectrochemical analyses for Sr and Pb, at the trace element 
level, tended to reflect the amount of aragonite present. With an increase of aragonite, 
there was an increase of Sr +2 and Pb +2 , and also an increase in the pH of the 
environment. An infrared method, based upon frequency change with changing 
composition, is correlated with the standard x-ray diffraction procedure for the 
determination of the Ca/Mg ratio within sample of 'protodolomite.'

Quarterly ichthyoplankton sampling was conducted at 16 estuarine and 24 inshore 
stations along the Florida Everglades from May 1971 to February 1972. The area is one 
of the most pristine along the Florida coast. The survey provided the first 
comprehensive information on seasonal occurrence, abundance (under 10 m 2 of surface 
area) and distribution of fish eggs and larvae in the area. A total of 209,462 fish eggs 
and 78,865 larvae was collected. Eggs were identified only as fish eggs, but among the 
larvae, 37 families, 47 genera, and 37 species were identified. Abundance of eggs and 
larvae, and diversity of larvae, were greatest in the inshore zone. The 10 most 
abundant fish families which together made up 90.7% of all larvae from the study area 
were in descending order of abundance: Clupeidae, Engraulidae, Gobiidae, Sciaenidae, 
Carangidae, Pomadasyidae, Cynoglossidae, Gerreidae, Triglidae, and Soleidae. 
Clupeidae, Engraulidae, and Gobiidae made up 59.9% of all larvae. The inshore zone (to 
a depth of about 10 m) was a spawning ground and nursery for many fishes important 
to fisheries. The catch of small larvae (<. 3.5 mm SL) indicated that most fishes 
identified from the 10 most abundant families spawned throughout the inshore zone at 
depths of 10 m, but Orthopristis chrysoptera , Gerreidae, and Prionotus spp. spawned 
at depths of 10 m, with offshore to inshore (eastward) larval transport. Salinity was 
one of several environmental factors that probably limited the numbers of eggs and 
larvae in the estuarine zone. Abundance of eggs and larvae at inshore stations was 
usually as great as, and sometimes greater than, the abundance of eggs and larvae at 
offshore stations due west of the Everglades.
