Geochemical maps showing distribution and abundance of manganese in two fractions of stream-sediment concentrates, Silver City 1 degree by 2 degrees Quadrangle, New Mexico and Arizona
Kenneth C. Watts, Jerry R. Hassemer, Carl L. Forn, David F. Siems
1986, Miscellaneous Field Studies Map 1183-J
These maps (Maps A and B) show the distribution and abundance of maganese in the nonmagnetic and magnetic fractions of heavy-mineral concentrates from stream sediments collected in the Silver City 1o x 2o quadrangle, New Mexico and Arizona. Geochemical maps showing the distribution and abundance of 10 other selected key elements and the mineral...
Free-air gravity anomaly map of the Long Island Platform
D. R. Hutchinson, W.D. Leeds, Robin Bell, J. A. Grow
1986, Miscellaneous Field Studies Map 1807
The U.S. Geological Survey (USGS) has collected marine gravity data along the U.S. Atlantic continental margin during the last decade. This map of the Long Island platform combines the data used to make the preliminary free-air gravity anomaly map of the Atlantic continental margin (Grow and others, 1976) with the...
Habitat Suitability Index Models: Brown thrasher
Brian S. Cade
1986, FWS/OBS 82/10.118
A review and synthesis of existing information were used to develop a Habitat Suitability Index (HSI) model for the brown thrasher (Toxostoma rufum). The model consolidates habitat use information into a framework appropriate for field application, and is scaled to produce an index between 0.0 (unsuitable habitat) to 1.0 (optimum...
Habitat Suitability Index Models and Instream Flow Suitability Curves: Chinook salmon
Robert F. Raleigh, William J. Miller, Patrick C. Nelson
1986, FWS/OBS 82/10.122
A review and synthesis of existing information were used to develop a Habitat Suitability Index (HSI) model for the Chinook salmon (Oncorhynchus tshawytscha). The model consolidates habitat use information into a framework appropriate for field application, and is scaled to produce an index between 0.0 (unsuitable habitat) to 1.0 (optimum...
Two-hundred years of hydrogeology in the United States
J.E. Moore, S. W. Lohman, E.B. Chase
J.S. Rosenshein, editor(s)
1986, Open-File Report 86-480
The Hydrogeology Division of the Geological Society of America (GSA) sponsored a symposium entitled ' Hydrogeology in the United States, 1776- 1976 ' at the annual meeting of the GSA on November 9, 1976. The symposium was organized to provide a forum for discussion of major eras in the history...
Habitat Suitability Index Models: Bald eagle (breeding season)
Allen Peterson
1986, FWS/OBS 82/10.126
A review and synthesis of existing information were used to develop a Habitat Suitability Index (HSI) model for the bald eagle (Haliaeetus leucocephalus). The model consolidates habitat use information into a framework appropriate for field application, and is scaled to produce an index between 0.0 (unsuitable habitat) to 1.0 (optimum...
Quaternary geologic map of the Jacksonville 4 degrees x 6 degrees quadrangle, United States
M.S. Knapp, M. S. Friddell, David L. Weide, David S. Fullerton
Gerald M. Richmond, editor(s)
1986, IMAP 1420(NH-17)
This map is part of the Quaternary Geologic Atlas of the United States (I-1420). It was first published as a printed edition in 1986. The geologic data have now been captured digitally and are presented here along with images of the printed map sheet and component parts as PDF files. The...
