Habitat islands and the equilibrium theory of island biogeography: testing some predictions Habitat islands and the equilibrium theory of island biogeography: testing some predictions

Species-area data from a study of marsh birds are used to test five predictions generated by the equilibrium theory of island biogeography. Three predictions are supported: we found a significant species-area relationship, a non-zero level of turnover, and a variance-mean ratio of 0.5. One prediction is rejected: the extinction rates were not greater on small islands. The results of one...

Ground-water data for Georgia, 1987 Ground-water data for Georgia, 1987

This report was prepared in cooperation with the State of Georgia; Chatham County; Glynn County; the cities of Brunswick and Valdosta; and the Albany Water, Gas, and Light Commission. This report is the culmination of a concerted effort by dedicated personnel of the U.S. Geological Survey who collected, compiled, analyzed, verified, and organized the data, and who edited and assembled...

Surface-water quality of the Cedar River basin, Iowa-Minnesota, with emphasis on the occurrence and transport of herbicides, May 1984 through November 1985 Surface-water quality of the Cedar River basin, Iowa-Minnesota, with emphasis on the occurrence and transport of herbicides, May 1984 through November 1985

The surface-water quality in the Cedar River basin was evaluated by analyzing the occurrence, distribution, and transport of common inorganic constituents and selected trace inorganic and organic constituents, with emphasis on herbicides. The surface-water quality of the Cedar River basin was monitored from May 1984 through November 1985. Depth integrated surface-water samples generally...

Freshwater supply potential of the Atlantic Intracoastal Waterway near Myrtle Beach, South Carolina Freshwater supply potential of the Atlantic Intracoastal Waterway near Myrtle Beach, South Carolina

A study was conducted to determine the low-flow frequency of freshwater flow in the Atlantic Intracoastal Waterway (AICW) near Myrtle Beach, South Carolina and to determine the effects of proposed freshwater withdrawals of 45 cu ft/sec at the location of the saltwater-freshwater interface. Discharges simulated in the AICW for 1982-86 using BRANCH one-dimensional flow model were used to...

U.S. Geological Survey ground-water studies in Iowa U.S. Geological Survey ground-water studies in Iowa

Ground water is the primary source for most water uses in Iowa. Ground-water resources supply 81 percent of the water withdrawn in Iowa for non-power-generating uses. Ground water from five principal aquifer systems is the source of drinking water for approximately 82 percent of the State's population. These aquifers range from land surface to several thousand feet below land surface...

Surface-water and water-quality data from selected streams and treated waters in the Greensboro Area, North Carolina, 1986-87 Surface-water and water-quality data from selected streams and treated waters in the Greensboro Area, North Carolina, 1986-87

Water and bottom-sediment samples were collected from April 1986 to September 1987 at 19 sites in Guilford County and the City of Greensboro, North Carolina. Sampling locations included 13 stream sites, two lakes that supply City of Greensboro drinking water, two City of Greensboro finished drinking-water filtration plants, and two municipal wastewater plants where effluents were sampled...

Simulation of saltwater movement in the Floridan aquifer system, Hilton Head Island, South Carolina Simulation of saltwater movement in the Floridan aquifer system, Hilton Head Island, South Carolina

Freshwater to supply Hilton Head Island, S.C., is obtained from the upper permeable zone of the Upper Floridan aquifer. Long-term pumping at Savannah, Ga., and the steadily increasing pumping on Hilton Head Island, have lowered Upper Floridan heads near the center of the island from about 10 feet above sea level to about 6 to 7 feet below sea level. The seaward hydraulic gradient that...

Aircraft MSS data registration and vegetation classification of wetland change detection Aircraft MSS data registration and vegetation classification of wetland change detection

Portions of the Savannah River floodplain swamp were evaluated for vegetation change using high resolution (5a??6 m) aircraft multispectral scanner (MSS) data. Image distortion from aircraft movement prevented precise image-to-image registration in some areas. However, when small scenes were used (200-250 ha), a first-order linear transformation provided registration accuracies of less...
