Piping Plover brood foraging ecology on New York barrier islands Piping Plover brood foraging ecology on New York barrier islands
Effective management of piping plover (Charadrius melodus) populations requires knowledge of the habitats that foster successful reproduction. We studied piping plover chick foraging ecology and survival on the central barrier islands of Long Island, New York, 1992 and 1993. Within the 90-km study area, all 1-km beach segments with ephemeral pools or bay tidal flats were used for nesting...

Simultaneous use of mark-recapture and radiotelemetry to estimate survival, movement, and capture rates Simultaneous use of mark-recapture and radiotelemetry to estimate survival, movement, and capture rates
Biologists often estimate separate survival and movement rates from radio-telemetry and mark-recapture data from the same study population. We describe a method for combining these data types in a single model to obtain joint, potentially less biased estimates of survival and movement that use all available data. We furnish an example using wood thrushes (Hylocichla mustelina) captured...

Influence of inner-continental shelf geologic framework on the evolution and behavior of the barrier-island system between Fire Island Inlet and Shinnecock Inlet, Long Island, New York Influence of inner-continental shelf geologic framework on the evolution and behavior of the barrier-island system between Fire Island Inlet and Shinnecock Inlet, Long Island, New York
High-resolution, sea-floor mapping techniques, including sidescan-sonar and subbottom profiling, were used to investigate how the geologic framework of the inner-continental shelf influenced the Holocene evolution and modern behavior of the Fire Island barrier-island system, Long Island, New York. The inner-continental shelf off Long Island is divided into two physiographic provinces by...

Suspended sediment in the Indiana Harbor Canal and the Grand Calumet River, northwestern Indiana, May 1996-June 1998 Suspended sediment in the Indiana Harbor Canal and the Grand Calumet River, northwestern Indiana, May 1996-June 1998
Suspended-sediment samples and streamflow data were collected from May 1996 through June 1998 at three sites in the Grand Calumet River Basin - Indiana Harbor Canal at East Chicago, the east branch of the Grand Calumet River at Gary, and the west branch of the Grand Calumet River at Hammond. Sample analysis allowed for retention of sediments of 0.0015 millimeters or larger.

Environmental Setting and Effects on Water Quality in the Great and Little Miami River Basins, Ohio and Indiana Environmental Setting and Effects on Water Quality in the Great and Little Miami River Basins, Ohio and Indiana
The Great and Little Miami River Basins drain approximately 7,354 square miles in southwestern Ohio and southeastern Indiana and are included in the more than 50 major river basins and aquifer systems selected for water-quality assessment as part of the U.S. Geological Survey's National Water-Quality Assessment Program. Principal streams include the Great and Little Miami Rivers in Ohio...

Analysis of atrazine and four degradation products in the pore water of the vadose zone, central Indiana Analysis of atrazine and four degradation products in the pore water of the vadose zone, central Indiana
A new method is described for the analysis of atrazine and four of its degradation products (desethylatrazine, deisopropylatrazine, didealkylatrazine, and hydroxyatrazine) in water. This method uses solid- phase extraction on a graphitized carbon black cartridge, derivatization of the eluate with N-methyl-N-(tert-butyldimethylsilyl)trifluoroacetamide (MTBSTFA), and analysis by gas...

Tracing sediment dispersal on nourished beaches: Two case studies Tracing sediment dispersal on nourished beaches: Two case studies
The event- to decade-scale patterns of sediment dispersal on two artificially nourished beaches have been mapped using a combination of geophysical surveys, closely-spaced vibracores, and repeated beach profiles. At both Wrightsville Beach, NC and Folly Island, SC the sediment used for beach nourishment is macroscopically distinct from native sediment and can be used to identify sediment...

Progress of environmental studies in coal mining areas of western Pennsylvania and central West Virginia Progress of environmental studies in coal mining areas of western Pennsylvania and central West Virginia
Two studies related to the regional environmental effects of coal mining in the Appalachian Plateau were conducted in 1998 as part of the National Water‐Quality Assessment program of the U.S. Geological Survey. The study area of about 20,000 square miles included parts of the Allegheny and Monongahela River basins in the north and the Kanawha River basin in the south. Water in domestic...
