Pliocene Fossils From Limestone in Southern Florida

Description: Abstract: This paper describes the mollusks and echinoids found in limestone dredged from ditches along the Tamiami Trail in southern Florida, in the area mapped as "Lostmans River limestone (Quaternary)" by Sanford but included in the Pliocene Caloosahatchee formation by Cooke and Mossom on the evidence of these fossils as identified by Mansfield. The matrix of the fossils is unlike the typical Caloosahatchee formation, which is sandy, but the fauna is closely related to that of the upper part of the Caloosahatchee formation and is regarded as a facies of the Caloosahatchee. The fauna shows considerable resemblance to that of the Imperial formation of California but may not be contemporaneous with it.

Uranium in the Southern United States

Description: From introduction: In this study on raw material sources of uranium the Southern Interstate Nuclear Board has catalogued all known occurrences of uranium and some references to thorium in a 17-state area (P1. 1). These occurrences have been evaluated as potential sources of uranium by the State Geological Surveys and the consultant group of SINB. Favorability guides have been applied to the known occurrences and recommendations have been made for future action by the states involved, federal agencies, or by industry. State recommendations are included in state-by-state summaries. The state reports were written either by personnel of the State Geological Surveys or were abstracted from State geological survey data by members of the consultant group...The purpose of this study was to compile information on and systematically assess uranium and other radioactive occurrences in the region. The SINB undertook the project because of its statutory, interstate capability as an extension of government in each of the 17 states, an arrangement that lends itself effectively to this cooperative undertaking.

Drainage Basins in Duval County, Florida

Description: "Duval County in northeastern Florida and adjacent to the Atlantic Ocean contains approximately 840 square miles of which approximately 80 square miles are covered by water. The county is drained by three major rivers, the St. Johns, Nassau, and St. Marys. In addition, the coastal areas are drained by numerous small streams that empty into the Intracoastal Waterway or the Atlantic Ocean."

Origins and Distribution of Saline Ground Waters in the Floridian Aquifer in Coastal Southwest Florida

Description: From introduction: Recognizing the need for comprehensive information about these waters of variable quality, the U.S. Geological Survey, in cooperation with the Southwest Florida Water Management District, investigated their character and distribution in the Mansota and lower Peace Basins (fig. 1). This report presents the results of the study. Principal objectives were to: (1) develop a better understanding of areal water-quality variations, and (2) relate the information developed to the extant concepts of the areal geohydrologic system.

Technique for Estimating Magnitude and Frequency of Floods on Natural-Flow Streams in Florida

Description: From introduction: The purpose of this report is to: (1) Present flood data for the gaged sites used in the flood-frequency analysis. (2) Describe the method of analysis used to develop the flood-estimating technique. (3) Provide regression equations for estimating floods on natural-flow (unregulated) streams. (4) Provide a method for improving the flood estimate at gaged sites. (5) Provide illustrative examples of applying the flood-estimating technique.

A Preliminary Appraisal of Sediment Sources and Transport in Kings Bay and Vicinity, Georgia and Florida

Description: From introduction: This report reviews descriptive background information of the Kings Bay area and presents data on currents, salinity, temperature, turbidity, suspended sediment, phytoplankton, and on the chemical and physical characteristics of bottom sediments. Water, salt, and suspended-sediment discharges are computed for consecutive ebbtides and floodtides that occurred during the November investigation.

The Effect of the Faka Union Canal System on Water Levels in the Fakahatchee Strand, Collier County, Florida

Description: From purpose and scope: The purpose of the investigation was to make a preliminary evaluation of the effects of the Faka Union Canal system on water levels in the Fakahatchee Strand. The evaluation includes more of a data collected specifically for the report as well as other data.

Results of Deep-Well Injection Testing at Mulberry, Florida

Description: From abstract: At the Kaiser Aluminum and Chemical Corporation plant, Mulberry, Florida, high-chloride, acidic liquid wastes are injected into a dolomite section at depths below about 4,000 feet below land surface. Sonar caliper logs made in April 1976 revealed a solution chamber that is about 100 feet in height and has a maximum diameter of 23 feet in the injection zone.

Hydrologic and Land-Cover Features of the Loxahatchee River Basin, Florida

Description: From purpose and scope: This map report represents the first published product of the Loxahatchee River estuary assessment, and primarily fulfills the first objective as outlined above. It presents an overview of the major physical features of the basin and presents selected information on the U.S. Geological Survey assessment.

Physical, Hydrological, and Biological Characteristics of the Loxahatchee River Estuary, Florida

Description: From purpose and scope: One of the objectives of the ongoing U.S. Geological Survey investigation of the Loxahatchee River estuary is to provide baseline information on the estuary. This map report was prepared to fulfill part of this objective. It provides information on bathymetry, hydrology, and benthic sediment and biota.

Chemical and Physical Characteristics of Precipitation at selected Sites in Florida

Description: From abstract: This report critically reviews historical precipitation data collected by the U.S. Geological Survey and concludes that the while the data "may reflect local atmospheric quality conditions they likely do not define baseline conditions from a regional perspective." It contains maps, graphs, and tables.

Analog-Model Simulations for Secondary Canal Controls and Forward Pumping Water-Management Schemes in Southeast Florida

Description: From purpose and scope: The purpose of this investigation is to evaluate, through electrical analog model simulation, the effects of two specific water-management proposals in Dade County. Proposal one is the installation of a secondary control on Snake Creek Canal and proposal two is the forward pumping scheme.

Aquifer Test Results, Green Swamp Area, Florida

Description: From abstract: "An aquifer test conducted in the Green Swamp area December 15-16, 1975 was designed to stress the uppermost part of the Flordian aquifer so that the leakage characteristics of the overlying confining bed could determined." This report includes those results.

Hydrologic Relations Between Lakes and Aquifers in a Recharge Area near Orlando, Florida

Description: Abstract: The three lakes investigated gain water- from adjoining water-table aquifer and lose water to Floridan aquifer by downward leakage. Net seepage (net exchange of water between lake and aquifers) can be estimated by equation S = AX + BY, where S is net seepage, X represents hydraulic gradient between lake and water-table aquifer, A is lumped parameter representing effect of hydaulic conductivity and cross-sectional area of materials in flow section of water-table aquifer, Y is head difference between lake level and potentiometric surface of Floridan aquifer, and B is lumped parameter representing effect of hydraulic conductivity, area, and thickness of materials between lake bottom and Floridan aquifer. If values of S, X, and Y are available for two contrasting water-level conditions, coefficients A and B are determinable by solution of two simultaneous equations. If the relation between lake- and ground-water level is same on all sides of the lake with regard to each aquifer and if X and Y are truly representative of these relations, then X and Y terms of equation provide valid estimates of inflow to lake from water-table aquifer and outflow from lake to Floridan aquifer.

Salt-Water Movement in the Lower Withlacoochee-Cross-Florida Barge Canal Complex

Description: The intent of the investigation was to determine how salt water from the Gulf moves in the river-canal complex under the influence of various combinations of fresh-water discharge and ocean tide. Information about the extent of inland movement, concentration, frequency of occurrence, and residence times of salt water in the river and canal was sought, particularly during times of farthest upstream movement of the salt water.
