 | Using multiple deployments of an 80-element, three-component borehole seismic array stretching from the surface to 2.3 km depth, we examine recordings of chemical explosions to better understand the generation of shear waves by explosive sources. The well is near vertical in the upper 1.5 km and gradually transitions to a dip of 38 degrees at the deepest recording location. The chemical shots are high-velocity chemical shots buried 3-4 m and ... |

|
| Grassland birds have undergone widespread decline throughout North America during the past several decades. Causes of this decline include habitat loss and fragmentation because of conversion of grasslands to cropland, afforestation in the East, brush and shrub invasion in the Southwest and western United States, and planting of exotic grass species to enhance forage production. A large number of exotic plant species, including grasses, have been introduced in North America, ... |

| During the last century, a large amount of the original bottomland hardwood forest area in the United States has been lost, with losses greatest in the Lower Mississippi Alluvial Valley and East Texas. With a holistic approach in mind, this manual describes methods to restore bottomland hardwoods in the lower Midwest, including the Lower Mississippi Alluvial Valley and the southeastern United States. Bottomland hardwoods in this guide include not only ... |

|
| Soil infiltration measurements were made at 23 sites in the Caloosahatchee River Basin in Glades, Hendry, and Lee Counties in southwestern Florida. The sandy soils of the basin are characterized by high infiltration rates limited in some areas by a high water table during the wet season. Because soil characteristics are similar within the basin, soils are classified by landscape group based on landscape cover and associated drainage. In accordance ... |

| Selected nitrogen and phosphorus (nutrient), suspended sediment and total suspended-solids surface water data were compiled from January 1980 through December 1995 within the Great Salt Lake Basins National Water-Quality Assessment study unit, which extends from southeastern Idaho to west-central Utah and from Great Salt Lake to the Wasatch and western Uinta Mountains. The data were retrieved from the U.S. Geological Survey National Water Information System and the State of Utah, ... |
