Water-resources data for the 1981 water year for Massachusetts and Rhode Island consist of records of stage, discharge, and water quality of streams; contents of lakes and reservoirs; and ground-water levels. This report contains discharge records for 100 gaging stations, month end contents for 30 lakes and reservoirs, water quality...
Habitat Suitability Index Models: Fox squirrel
Arthur W. Allen
1982, FWS/OBS 82/10.18
The fox squirrel (Sciurus niger) is the largest of the North American tree squirrels. The species is widely distributed throughout eastern North American and has been introduced in many portions of the West (Wright 1979). Fox squirrels also have expanded their range westward through utilization of gallery forest habitats along...
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: Bluegill
Robert J. Stuber, Glen Gebhart, O. Eugene Maughan
1982, FWS/OBS 82/10.8
A literature review encompassing habitat and species characteristics of the bluegill (Lepomis macrochirus) is followed by a discussion of the relationship of habitat variables and life requisites of this species. These data re then incorporated into Habitat Suitability Index models for the bluegill. This is one in a series of publications...
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...
Mineral resource potential map of the John Muir Wilderness, Fresno, Inyo, Madera, and Mono counties, California
E. A. Du Bray, D. A. Dellinger, M. F. Diggles, H. W. Oliver, F. L. Johnson, H. K. Thurber, R.W. Morris, T.J. Perers, D.S. Lindsey
1982, Miscellaneous Field Studies Map 1185-C
Under the provisions of the Wilderness Act (Public Law 88-577, September 3, 1964) and the Joint Conference Report on Senate Bill 4, 88th Congress, the U.S. Geological Survey and the U.S. Bureau of Mines have been conducting mineral surveys of wilderness and primitive areas. Areas officially designated as "wilderness," "wild,"...
Mineral resource potential map of the Hells Hole further planning area (RARE II), Greenlee County, Arizona, and Grant County, New Mexico
J.C. Ratte, J.R. Hassemer, R.A. Martin, J. P. Briggs
1982, Miscellaneous Field Studies Map 1344-E
During 1979, the U.S. Geological Survey and the U.S. Bureau of Mines conducted field investigations to evaluate the mineral resource potential of the Hells Hole Further Planning Area. The investigations included geologic mapping, geophysical studies, geochemical sampling, and a survey of known mines, prospects, and mineralized areas. This report summarizes...
Mineral resource potential of the Granite Chief Wilderness Study Area, Placer County, California
David S. Harwood, Francis E. Federspiel, Eric E. Cather, Douglas F. Scott
1982, Miscellaneous Field Studies Map 1273-C
A mineral resource survey of the Granite Chief Wilderness Study Area in the Tahoe National Forest and Lake Tahoe Management Area was conducted between 1979 and 1981. The mineral resource potential of the area was evaluated from geologic and geochemical studies by the U.S. Geological Survey, and from the examination...
Mineral resource potential map of the Gila-San Francisco Wilderness Study Area, Graham and Greenlee counties, Arizona
Donlad H. Richter, Douglas P. Klein, Viki A. Lawrence, Michael Lane
1982, Miscellaneous Field Studies Map 1315-B
The mineral resource potential of the Gila-San Francisco Wilderness Study Area (AZ-040-022/023/024) is low (fig. 2). Although favorable geologic environments for placer gold deposits and manganese vein deposits are present in the study area, the probability of discovering economically exploitable deposits of these metals is low, and not encouraging. Even...
Mineral resource potential map of the Clear Lake Roadless Area, Leon County, Florida
Charles W. Hendry Jr., Sam H. Patterson, Thomas M. Crandall, John W. Sweeney
1982, Miscellaneous Field Studies Map 1479
The only mineral material that has been produced within the Clear Lake Roadless Area is clayey sand used as fill for highway construction and for stabilizing Forest Service roads. Fuller's earth, common clay, and sand and gravel presently are produced in Leon County and in nearby counties, and limestone and...
Mineral resource potential map of the Bighorn Mountains Wilderness Study Area (CDCA-217), San Bernardino County, California
Jonathan C. Matti, Brett F. Cox, Eduardo A. Rodriguez, Curtis M. Obi, Robert E. Powell, Margaret Hinkle, Andrew Griscom, Charles Sabine, Gary J. Cwick
1982, Miscellaneous Field Studies Map 1493-A
Geological, geochemical, and geophysical evidence, together with a review of historical mining and prospecting activities, suggests that most of the Bighorn Mountains Wilderness Study Area has low potential for the discovery of all types of mineral and energy resources-including precious and base metals, building stone and aggregate, fossil fuels, radioactive-mineral...
Preliminary geological investigation of the Bir Hayzan diatomite deposit, Kingdom of Saudi Arabia, with a section on selected physical properties and implications for future geophysical exploration
J.W. Whitney, M. E. Gettings
1982, Open-File Report 82-1046
A 2.2-m-thick lake bed composed entirely of diatomite was found in the southwestern arm of the Nafud sand sea, about 67 km east of Tayma in northwestern Saudi Arabia. Its stratigraphic position above eolian sand and below a large barchanoid dune indicates deposition during an exceptional period of pluvial climate...
