Habitat relationships of island nesting seabirds along Coastal Louisiana Habitat relationships of island nesting seabirds along Coastal Louisiana
Seabirds in the saline marsh of coastal Louisiana nest on the islands that are more isolated, smaller, have lower percentages of woody vegetation, and higher percentages of herbaceous vegetation and beach habitat. Only moderate variation in these habitat features was demonstrated among years of colonization. The factors causing these preferences appear to be protection from mammalian...

Biochemical changes in longear sunfish, Lepomis megalotis, associated with lead, cadmium and zinc from mine tailings Biochemical changes in longear sunfish, Lepomis megalotis, associated with lead, cadmium and zinc from mine tailings
Longear sunfish were collected from a stream contaminated with mine tailings rich in lead (Pb), cadmium (Cd) and zinc (Zn). Blood samples were analysed for δ-aminolevulinic acid dehydratase (ALA-D) activity and Pb concentration. Vertebrae were tested for bone strength and composition, and Pb, Zn, and Cd concentrations were determined in muscle tissue. ALA-D activity was negatively...

The ecology of the soft-bottom benthos of San Francisco Bay: a community profile The ecology of the soft-bottom benthos of San Francisco Bay: a community profile
This profile, part of a series of profiles concerning coastal habitats of the United States, is a detailed examination of the soft-bottom benthos of San Francisco Bay. A U.S. Fish and Wildlife Service and California Department of Fish and Game report (1979) entitled "Protection and Restoration of San Francisco Bay Fish and Wildlife Habitat" provides clear recognition of the importance of

Use of GIS technologies in addressing resource management problems in Mobile Bay, Alabama Use of GIS technologies in addressing resource management problems in Mobile Bay, Alabama
Geographic Information Systems (GIS) technologies are being used in three neutral resource management studies of Mobile Bay, AL. Each study is briefly discussed. In the first, the GIS was used to analyze wetland habitat changes in the bay over a 25-year period. In the second, cartographic modeling techniques are being used to assess the potential impacts of contaminated sediments on...

Direct-current resistivity data from 94 sites in northeastern Palm Beach County, Florida Direct-current resistivity data from 94 sites in northeastern Palm Beach County, Florida
Direct-current resistivity data were collected from 94 vertical electric sounding profiles in northeastern Palm Beach County, Florida. Direct-current resistivity data, which may be used to determine the location and thicknesses of shallow, semipermeable marls or locate zones of high chloride concentration, are presented in this report. The resistivity data consist of field data, smoothed...

Effects of two stormwater management methods on the quality of water in the upper Biscayne aquifer at two commercial areas in Dade County, Florida Effects of two stormwater management methods on the quality of water in the upper Biscayne aquifer at two commercial areas in Dade County, Florida
This study is part of a continued effort to assess the effects of urban stormwater recharge on the water quality of the Biscayne aquifer in southeast Florida. In this report, the water-quality effects on shallow ground water resulting from stormwater disposal by exfiltration trench and grassy swale were investigated at two small commercial areas in Dade County, Florida. One study area...

Water withdrawals, use, and trends in Florida, 1985 Water withdrawals, use, and trends in Florida, 1985
Total water withdrawn for use in Florida for 1985, in million gal/day, was 17,057 of which 6,259, or nearly 37%, was freshwater and 10,798 was saline. The majority of freshwater withdrawn was groundwater (64%) and the majority of saline water withdrawn was surface water (99%). Thermoelectric power generation accounted for more than 99% of saline water withdrawals. Agricultural irrigation...

Ground-water flow beneath levee 35A from conservation area 2B, Broward County, Florida Ground-water flow beneath levee 35A from conservation area 2B, Broward County, Florida
Conservation Area 2B is an area of recharge for the surficial aquifer system in Broward County. Water stored in the conservation area provides the hydraulic potential for downward flow to the high permeability zone of the Biscayne aquifer. A 5.64 ft head differential (average for the period of record) between water levels in Conservation Area 2B and water levels in the adjacent levee 35A...
