Heat-flow measurements at shot points along the 1978 Saudi Arabia seismic deep-refraction line; Part I, Results of the measurements
M. E. Gettings, Abdullah Showail
1982, Open-File Report 82-793
Heat-flow measurements were made at five onland shot points of the 1978 Saudi Arabian seismic deep-refraction line, which sample major tectonic elements of the Arabian Shield along a profile from Ar Riyad to the Farasan Islands. Because of the pattern drilling at each shot point, several holes (60 m deep)...
Multielement chemical and statistical analyses from a uranium hydrogeochemical and stream-sediment survey in and near the Elkhorn Mountains, Jefferson County, Montana. Part I: Surface water
V. J. Suits, K. J. Wenrich
1982, Open-File Report 82-203-A
Fifty-two surface-water samples, collected from an area south of Helena, Jefferson County, were analyzed for 51 chemical species. Of these variables, 35 showed detectable variation over the area, and 29 were utilized in a correlation analysis. Two populations are distinguished in the collected samples and are especially evident in the...
Position of the saltwater-freshwater interface in the upper part of the Floridan Aquifer, southwest Florida, 1979
K.W. Causseaux, J. D. Fretwell
1982, Open-File Report 82-90
Ground-water withdrawals in southwest Florida are increasing because of urban growth, industrial expansion and increased agricultural irrigation. As a result, the potentiometric surface of the Floridian aquifer has been lowered in some areas, allowing seawater to encroach into the aquifer and threaten the freshwater resources of the area. Effective management...
Habitat Suitability Index Models: Eastern meadowlark
Richard L. Schroeder, Patrick J. Sousa
1982, FWS/OBS 82/10.29
Habitat preferences of the eastern meadowlark (Sturnella magna) are described in this publication, which is one of a series of Habitat Suitability Index (HSI) models. Habitat use information is presented in a synthesis of the literature on the species-habitat requirements of the eastern meadowlark, followed by the development of the...
Habitat Suitability Index Models: Beaver
Arthur W. Allen
1982, FWS/OBS 82/10.30
Habitat preferences of the beaver (Castor canadensis) are described in this publication, which is one of a series of Habitat Suitability Index (HSI) models. Habitat use information is presented in a synthesis of the literature on the species-habitat requirements of the beaver, followed by the development of the HSI model....
Carolina Trough structure contour maps
Charles K. Paull, William P. Dillon
1982, Miscellaneous Field Studies Map 1402
Four strong reflection horizons identified on multichannel seismic-reflection profiles of the U.S. continental margin east of the Carolinas have been traced and contoured (maps A-D).  Depths, in kilometers, to the horizons were calculated by the method of Taner and Koehler (1969) using the reflection-time and RMS (root-mean-square) velocities from multichannel...
Mineral resource potential map of the Savannah Roadless Area, Liberty County, Florida
Sam H. Patterson, Walter Schmidt, Thomas M. Crandall
1982, Miscellaneous Field Studies Map 1470
The Savannah Roadless Area is underlain by sedimentary rocks having low potential for oil and gas and minerals. The low potential for oil or gas notwithstanding, the possibilities for discovery cannot be ruled out because the area and nearby lands have not been thoroughly explored. No minerals have been mined...
Photographs of the Upper Pleistocene section at Sankaty Head cliff, Nantucket Island, Massachusetts
Robert N. Oldale
1982, Miscellaneous Field Studies Map 1397
The pre-Sangamonian and Wisconsinan glacial drift units and Sangamonian marine beds exposed tin the Sankaty Head cliff (fig. 1) constitute a unique and important upper Pleistocene stratigraphic section in southern New England. Many workers have studied the section over the past 130 years, paying most attention to the fossiliferous Sankaty...
The Alaska Mineral Resource Assessment Program: Guide to information about the geology and mineral resources of the Ketchikan and Prince Rupert quadrangles, southeastern Alaska
Henry C. Berg
1982, Circular 855
The Ketchikan and Prince Rupert 1-degree by 2-degree quadrangles, which encompass about 16,000 km2 at the south tip of southeastern Alaska, have been investigated by integrated field and laboratory studies in the disciplines of geology, geochemistry, geophysics, and Landsat data interpretation to determine their mineral-resource potential. Mineral deposits in the...
Habitat Suitability Index Models: Juvenile spot
Robert R. Stickney, Michael L. Cuenco
1982, FWS/OBS 82/10.20
A review and synthesis of existing information were used to develop estuarine habitat models for juvenile spot (Leiostomus xanthurus). The models are scaled to produce an index of habitat suitability between 0 (unsuitable habitat) to 1 (optimally suitable habitat) for estuarine areas of the continental United States. Habitat suitability indexes...
Habitat Suitability Index Models: Veery
Patrick J. Sousa
1982, FWS/OBS 82/10.22
Habitat preferences and species characteristics of the veery (Catharus fuscesens) 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 scientific data on the habitat requirements of the veery. Habitat use information is presented in...
