Dennis K. Demcheck, Alton J. Dupuy
1980, Open-File Report 80-434
Samples consisting of composited core material were collected from five areas by the U.S. Army Corps of Engineers and analyzed by the U.S. Geological Survey to provide data on the impact of proposed channel excavation and levee construction in the Sicily Island area, Louisiana. Samples of receiving water from the...

1980, Professional Paper 1109
Six Coastal Plain formations and one group crop out in the Round Bay quadrangle near the inner edge of the Atlantic Coastal Plain physiographic province. The quadrangle lies astride the Severn River, in Anne Arundel County, near Annapolis, Md. The seven stratigraphic units aggregate as much as 128 m in...

Preliminary bathymetry of Northwestern Fiord and neoglacial changes of Northwestern Glacier, Alaska
Austin Post
1980, Open-File Report 80-414
The first preliminary bathymetry (at 1:20,000 scale) and other scientific investigations of Northwestern Fiord, Alaska, were conducted by the Research Vessel Growler in 1978, disclosing this 10.5-mile-long branched waterway to be a deep basin enclosed by a terminal-moraine shoal. The basin was formerly filled by Northwestern Glacier, which began a...

This report presents a collection of Nevada Test Site (NTS) nuclear explosion recordings obtained at sites in the greater Los Angeles, Calif., region. The report includes ground velocity time histories, as well as, derived site transfer functions. These data have been collected as part of a study to evaluate the...
Map showing general chemical quality of surface water in the Alton-Kolob coal-fields area, Utah
Don Price
1980, IMAP 1235-A
This is one of a series of maps that describes the geology and related natural resources of the Alton-Kolob coal-fields area, Utah. The purpose of this map is to show the general chemical quality of surface water in the area by ranges of dissolved-solids concentrations (salinity) known or assumed to...
Physical environment and hydrologic characteristics of coal-mining areas in Missouri
J. E. Vaill, James H. Barks
1980, Water-Resources Investigations Report 80-67
Hydrologic information for the north-central and western coal-mining regions of Missouri is needed to define the hydrologic system in these areas of major historic and planned coal development. This report describes the physical setting, climate, coal-mining practices, general hydrologic system, and the current (1980) hydrologie data base in these two...

Preimpoundment water quality of the Wild Rice River, Norman County, Minnesota
L. H. Tornes
1980, Water-Resources Investigations Report 80-79
Water samples have been collected at two sites on the Wild Rice River since September 1974 to establish baseline water-quality characteristics before construction of a reservoir for recreation and flood control near Twin Valley, Minn. A decline in water quality between the sites is shown by mean total phosphorus concentrations,...

Analysis of borehole geophysical data in an evaporite sequence at Salt Valley, Utah
Jeffrey J. Daniels, James H. Scott, Robert J. Hite
1980, Open-File Report 80-525
Interpretation of the lithology of an interbed sequence (thin-bedded sediments between thick layers of salt) is often difficult due to the presence of dolomitic sandstones and halite inclusions. The most useful well logging measurements in an evaporite sequence are gamma-ray, neutron-neutron, density, and acoustic velocity. The high resistivity of salt...
