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...

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...

Circulation and sediment transport in the vicinity of the Hudson Shelf Valley Circulation and sediment transport in the vicinity of the Hudson Shelf Valley
Sediment transport in the Hudson Shelf Valley and on the adjacent Long Island Shelf are evaluated using available data along with a three-dimensional wind-driven circulation model and a one-dimensional sediment transport model. Winds from the northwest drive currents up the Hudson Shelf Valley, while winds from the east produce weaker currents directed down the valley. Consistent with...

Global GIS database. Digital atlas of Central and South America Global GIS database. Digital atlas of Central and South America
This CD-ROM contains a digital atlas of the countries of Central and South America. This atlas is part of a global database compiled from USGS and other data sources at the nominal scale of 1:1 million and is intended to be used as a regional-scale reference and analytical tool by government officials, researchers, the private sector, and the general public. The atlas includes free GIS...
