The following report is the results of a workshop held to determine the cause of fibropapilloma (lobulated tumors), thereby ultimately leading to solutions and effective strategies for containment. The urgent need to solve this problem arises from the unanimous belief among the workshop participants that this disease will continue to affect populations of turtles locally and worldwide, adding further to their survival difficulties. The workshop was held in December of 1990 and the research behind the workshop results from about 10 years of observing the species.

From introduction: The purpose of this report is (1) to describe the geology, hydrology, and quality of water of Manatee County and (2) to evaluate the availability of surface and ground water for development. The report provides Manatee County, the Southwest Florida Water Management District, and the Florida Department of Natural Resources with a data base and an evaluation of the water resources of the area so that water-quality and water-resource problems and water-management and regulatory needs can be adequately defined and documented.

From foreword: The results of an engineering study directed toward the evaluation and selection of a nuclear reactor system designed to produce electricity and furnish steam to a water desalination plant in the Florida Keys are given in this report.

Partial abstract: "This report reviews the scope of a research effort initiated in 1974 at the U.S. Army Engineer Waterways Experiment Station with the objectives of (a) assessing the state of the art in geophysical cavity detection and delineation methodology and (b) developing new methods and improving or adapting old methods for application to cavity detection and delineation." This report discusses the geography, topography, site drilling tests, magnetic and microgravimetric surveys, and other information about the Medfor Cave site in Florida.

From introduction: The purpose of this report is to present irrigation water-use data for selected farms and to show how these data are used to estimate total water use for irrigating various crops in southwest Florida. The study area includes all of the Southwest Florida Water Management District and is about 10,000 miles in size (figure 1). The initial emphasis on benchmark farm locations was in Hillsborough, Manatee, and Polk Counties. As the program continues, new farms are being added in surrounding counties (figure 2).

From abstract: Areas of abnormal radioactivity south of Ocala, Marion County, Fla., discovered in 1953 by aerial survey, were investigated by surface examination and by 10 power auger drill holes. Interbedded clay, clayey sand, and uraniferous phosphorite occur in the areas of anomalous radioactivity. Miocene fossils occur at three localities in these beds which are evidently outliers of Miocene sediments on the Ocala limestone of Eocene age. The preserved outliers are southwest of the main belt of Miocene sediments. The principal uraniferous rocks are clayey, sandy, pellet phosphorite that occurs in beds a few feet thick, and very porous, phosphatic sand rock which makes abundant float at many places. Apatite forms the phosphate pellets in the unweathered phosphorite. The very porous, phosphatic sand rock is the highly leached residuum of the pellet phosphorite and is composed mainly of quartz, kaolinite, wavellite, and crandallite ( pseudowavellite2). It closely resembles the aluminum phosphate rock of the "leached zone" of the Bone Valley formation in the land-pebble phosphate district.

Abstract: The Pinellas County landfill site is on a flat, coastal area characterized by a nearsurface water table. Part of the site is subject to tidal flooding; altitudes within the study area range from 8 to 12 feet above sea level. Three geohydrologic units underlie the landfill site. In descending order, these are: a surficial aquifer about 19 feet thick composed of sand and shell, a confining bed about 35 feet thick composed of marl and clay, and the Floridan aquifer composed of limestone. Landfill operations have not altered surface-water quality. Although leachate movement downward into the Floridan _aquifer is not indicated, vertical movement through the confining bed is about 0.005 foot per year. The rate of lateral movement of ground-water away from the site is about 1.2 feet per year; . however, the rate of movement along the boundary from the oldest section of the landfill through the surficial aquifer is about 20 feet per year. Peaks in concentration of selected chemical parameters and flow-rate analysis of water from trenches indicate the possibility of intermittent release of leachate from the landfill.

Report discussing studies of millisite and pseudowavellite, which were "locally abundant in the leached zone of the highly phosphatic Bone Valley formation in west-central Florida." Studies include optical determinations and x-ray studies.

"This report presents the hydraulic and chemical data collected at a deep-well waste-injection system near Pensacola, Florida." It includes maps, graphs, and tables.

The results obtained from gust and draft velocity measurements within thunderstorms for the period July 24, 1946 to August 6, 1946 at Orlando, Florida are presented herein. These data are summarized in tables I and II and are of the type presented in reference 1 for previous flights. In two thunderstorm traverses, indications of ambient-air temperature were obtained from photo-observer records. These data are summarized in table III.

Abstract: Kissimmee River structures S-65E, S-65D, and S-65B were reproduced in a 1:20 scale model in order to study ways of eliminating scour of the downstream riprap blankets by means of structural modifications of operating procedures.

Abstract: A flowing artesian well tapping the Floridan aquifer at Chekika Hammock State Park, Dade County, Florida, has been contaminating the overlying Biscayne aquifer with saline water since 1944. The contaminating plume extends approximately 7 miles downstream and southeast of the well and ranges in width from 1 to 2 miles. The area of contamination is approximately 12 square miles. The primary contaminating chemical constituents are chloride, sodium, and sulfate ions.
