Temporal and geographic patterns in population trends of brown-headed cowbirds Temporal and geographic patterns in population trends of brown-headed cowbirds
The temporal and geographic patterns in the population trends of Brown-headed Cowbirds are summarized from the North American Breeding Bird Survey. During 1966-1992, the survey-wide population declined significantly, a result of declining populations in the Eastern BBS Region, southern Great Plains, and the Pacific coast states. Increasing populations were most evident in the northern...

Status and trends in suspended-sediment discharges, soil erosion, and conservation tillage in the Maumee River basin: Ohio, Michigan, and Indiana Status and trends in suspended-sediment discharges, soil erosion, and conservation tillage in the Maumee River basin: Ohio, Michigan, and Indiana
The relation of suspended-sediment discharges to conservation-tillage practices and soil loss were analyzed for the Maumee River Basin in Ohio, Michigan, and Indiana as part of the U.S. Geological Survey’s National Water-Quality Assessment Program. Cropland in the basin is the largest contributor to soil erosion and suspended-sediment discharge to the Maumee River and the river is the...

Titanium mineral resources of the western U.S.: An update Titanium mineral resources of the western U.S.: An update
Thirteen deposits or districts in the western U.S. have been examined in which titanium mineral resources have been reported or implied. These deposits are of the following general types (in probable order of importance): 1) Cretaceous shoreline placer deposits, 2) silica-sand deposits of California, 3) fluvial monazite placers of Idaho, 4) anorthosite related deposits, and 5) clay and...

A Synopsis of Technical Issues for Monitoring Sediment in Highway and Urban Runoff A Synopsis of Technical Issues for Monitoring Sediment in Highway and Urban Runoff
Accurate and representative sediment data are critical for assessing the potential effects of highway and urban runoff on receiving waters. The U.S. Environmental Protection Agency identified sediment as the most widespread pollutant in the Nation's rivers and streams, affecting aquatic habitat, drinking water treatment processes, and recreational uses of rivers, lakes, and estuaries

Formation of natural gas hydrates in marine sediments. Gas hydrate growth and stability conditioned by host sediment properties Formation of natural gas hydrates in marine sediments. Gas hydrate growth and stability conditioned by host sediment properties
The stability conditions of submarine gas hydrates (methane clathrates) are largely dictated by pressure, temperature, gas composition, and pore water salinity. However, the physical properties and surface chemistry of the host sediments also affect the thermodynamic state, growth kinetics, spatial distributions, and growth forms of clathrates. Our model presumes that gas hydrate behaves...

Concentrations of Escherichia Coli in Streams in the Upper Wabash River Watershed in Indiana, June-September 1998 Concentrations of Escherichia Coli in Streams in the Upper Wabash River Watershed in Indiana, June-September 1998
Water samples collected from 46 stream sites in the Upper Wabash River Watershed from June through September 1998 were analyzed for concentrations of the bacteria Escherichia coli (E. coli). Each site was sampled five times in a 30-day period. Twenty-one sites were sampled during June and July, and 25 sites were sampled during August and September. The concentration of E. coli in 145 of...
