Habitat Suitability Index Models: Yellow warbler
Richard L. Schroeder
1982, FWS/OBS 82/10.27
Habitat preferences of the yellow warbler (Dendroica petechia) are described in this publication. It is one of a series of Habitat Suitability Index (HSI) models and was developed through an analysis of available information on the species-habitat requirements of the species. Habitat use information is presented in a review of...
The densities of halite-saturated WIPP-A and NBT-6 brines and their NaCl contents in weight percent, molal, and molar units from 20 to 100 degrees C
I-Ming Chou, B. Buizinga, M.A. Clynne, R.W. Potter
1982, Open-File Report 82-899
A series of density measurements has been performed at 30?, 50?, 70?, and 90?C for halite-undersaturated WIPP-A and NBT-6 brines with various NaCl contents approaching saturation. The densities of halite-saturated WIPP-A and NBT-6 brines were obtained by extrapolating these measured densities to halite saturation points. The maximum difference between the...

1982, Professional Paper 1067-E
Geologic mapping in conjunction with uranium-series dating of fossil mollusks and corals suggests that the low-lying ( < 17 m in altitude) terrace deposits in the central and southern Chesapeake Bay area include two main depositional sequences, each of which represents a high stand of the sea in late Pleistocene...

Habitat suitability index models: Channel catfish
Thomas E. McMahon, James W. Terrell
1982, FWS/OBS 82/10.2
The native range of channel catfish (Ictalurus Runctatus) extends from the southern portions of the Canadian prairie provinces south to the Gulf states, west to the Rocky Mountains, and east to the Appalachian Mountains (Trautman 1957; Miller 1966; Scott and Crossman 1973). They have been widely introduced outside this range...

Eruptive history, petrology, and petrogenesis of the Joe Lott Tuff Member of the Mount Belknap Volcanics, Marysvale volcanic field, west-central Utah
Karin E. Budding
1982, Open-File Report 82-891
The Joe Lott Tuff Member of the Mount Belknap Volcanics is the largest rhyolitic ash-flow tuff sheet in the Marysvale volcanic field. It was erupted 19 m.y. ago, shortly after the changeover from intermediate-composition calc-alkalic volcanism to bimodal basalt-rhyolite volcanism. Eruption of the tuff resulted in the formation of the...
Downstream effects of reservoir releases to the Potomac River from Luke, Maryland, to Washington, D.C.
T. J. Trombley
1982, Water-Resources Investigations Report 82-4062
A digital computer flow-routing model was developed for the Potomac River in order to determine the downstream effects of flow releases from the Bloomington and Savage River Reservoirs. Both reservoirs are located above Luke, Maryland approximately 230 miles upstream from Washington, D. C. The downstream effects of reservoir releases were...
Depth and temperature of permafrost on the Alaskan Arctic Slope; preliminary results
Arthur H. Lachenbruch, J.H. Sass, L.A. Lawver, M.C. Brewer, T.H. Moses
1982, Open-File Report 82-1039
As permafrost is defined by its temperature, the only way to determine its depth is to monitor the return to equilibrium of temperatures in boreholes that penetrate permafrost. Such measurements are under way in 25 wells on the Alaskan Arctic Slope; 21 are in Naval Petroleum Reserve Alaska (NPRA), and...
Habitat Suitability Index Models: Southern kingfish

1982, FWS/OBS 82/10.31
The habitat use information and habitat suitability index (HSI) models in this report on southern kingfish are intended for use in impact assessment and habitat management. The models were developed from a review and synthesis of existing information and are scaled to produce an index of habitat suitability between 0...
Habitat Suitability Index Models: Juvenile Atlantic Croaker
Robert J. Diaz, Christopher P. Onuf
1982, FWS/OBS 82/10.98
INTRODUCTION The Atlantic croaker is an important commercial and recreational species. In the 1940's, the foodfish catch of Atlantic croakers was concentrated in Chesapeake Bay; in the 1950's and early 1970's, the catch was concentrated in the Gulf of Mexico; and in the late 1970's, the catch was concentrated in the...
Preliminary evaluation of the ground-water-flow system in the Twin Cities Metropolitan area, Minnesota

1982, Water-Resources Investigations Report 82-44
A preliminary quasi-three-dimensional finite-difference ground-water-flow model of the seven-county Twin Cities Metropolitan area was constructed and used to evaluate parameter sensitivity and adequacy of available data. Fourteen geologic units that underlie the study area were grouped into nine hydr,bgeologic units and were incorporated into a five-layer model. The layers in...
Potential impacts of a proposed reservoir on hydrologic and water-quality conditions in Little Rush Creek watershed, Fairfield County, Ohio
Janet Hren, R.L. Jones
1982, Open-File Report 82-109
Water-quality and discharge measurements were made at three sites on Indian Run and one site on Little Rush Creek between February and December, 1979. Indian Run was observed above and below the U.S. Soil Conservation Service Reservoir, VI-D. Little Rush Creek was observed 1.1 miles downstream from the proposed U.S....
Hydrologic effects of storing liquified sewage sludge on strip-mined land, Fulton County, Illinois
G. L. Patterson
1982, Water-Resources Investigations Report 82-4047
The water table near four sewage storage basins in a strip-mined area of western Illinois, has risen about 10 feet since the basins were constructed in 1971. Two dimensional modeling of ground-water flow in the mine spoil indicates that the rise is caused by leakage from one storage basin. The...
Uranium in Wheeler Basin, Grand County, Colorado
E. J. Young
1982, Open-File Report 82-730
Two kinds of radioactive anomalies are found in Wheeler Basin, both of which consist of biotite concentrations in Precambrian rocks, but the ones in migmatized biotite gneiss contain uraninite and the ones in Silver Plume Granite probably do not. At least 18 new uranium occurrences were found, most of which...
Evapotranspiration of applied water, Central Valley, California, 1957-78
Alex K. Williamson
1982, Water-Resources Investigations Report 81-45
In the Central Valley, Calif., where 57% of the 20,000 square miles of land is irrigated, ground-water recharge from agricultural lands is an important input to digital simulation models of ground-water flow. Several methods of calculating recharge were explored for the Central Valley Aquifer Project and a simplified water budget...

The COST Nos. G-1 and G-2 wells (fig. 1) are the second and third deep stratigraphic test wells drilled in the North Atlantic Outer Continental Shelf of the United States. COST No. G-1 was drilled in the Georges Bank basin to a total depth of 16,071 ft (4,898 m). G-1...
Ground-water applications of remote sensing
Gerald K. Moore
1982, Open-File Report 82-240
Remote sensing can be used as a tool to inventory springs and seeps and to interpret lithology, structure, and ground-water occurrence and quality. Thermograms are the best images for inventory of seeps and springs. The steps in aquifer mapping are image analysis and interpretation and ground-water interpretation. A ground-water interpretation...
Model modifications for simulation of flow through stratified rocks in eastern Ohio
J. O. Helgesen, A. C. Razem, S. P. Larson
1982, Water-Resources Investigations Report 82-4019
A quasi three-dimensional groundwater flow model is being used as part of a study to determine impacts of coal-strip mining on local hydrologic systems. Modifications to the model were necessary to simulate local hydrologic conditions properly. Perched water tables required that the method of calculating vertical flow rate be changed....
