Forward and inverse cartographic projection procedures
G. I. Evenden
1983, Open-File Report 83-625
A set of procedures for performing 19 common cartographic transformations between geographic and artesian coordinate systems are presented along with instruction for usage, installation and testing results. These procedures are written in the RATFOR preprocessor language and effort was made to ensure transportability of the code as well as consistency...
Habitat Suitability Index Models: Common shiner
Joan G. Trial, Charles S. Wade, Jon G. Stanley, Patrick C. Nelson
1983, FWS/OBS 82/10.40
A review and synthesis of existing information were used to develop riverine and lacustrine habitat models for common shiner (Notropis cornutus). The models are scaled to produce an index of habitat suitability between 0 (unsuitable habitat) to 1 (optimally suitable habitat) for the northeastern range of the common shiner in...
Hydrogeology of the Sarasota-Port Charlotte area, Florida
R. M. Wolansky
1983, Water-Resources Investigations Report 82-4089
The surficial and intermediate aquifers are the major source of public water supplies in the Sarasota-Port Charlotte, Florida, area because of the relatively poor quality of Floridan aquifer water. The hydrogeologic framework consists of the surficial aquifer, intermediate aquifers (Tamiami-upper Hawthorn and lower Hawthorn-upper Tampa aquifers) and confining beds, Floridan...
Stratigraphy and paleontology of Mid-Cretaceous rocks in Minnesota and contiguous areas
William Aubrey Cobban, E.A. Merewether
1983, Professional Paper 1253
PART A: Molluscan fossils are locally abundant at outcrops of Upper Cretaceous rocks in eastern North and South Dakota, northeastern Nebraska, northwestern Iowa, and western and northern Minnesota. Other Cretaceous mollusks have been found in the glacial deposits in Minnesota, Iowa, and Illinois. The oldest well dated marine mollusks are...
Statistical summary of daily values data and trend analysis of dissolved-solids data at National Stream Quality Accounting Network (NASQAN) stations
F.C. Wells, T. L. Schertz
1983, Water-Resources Investigations Report 83-4172
A statistical summary is provided of the available continuous and once-daily discharge, specific-conductance, dissolved oxygen , water temperature, and pH data collected at NASQAN stations during the 1973-81 water years and documents the period of record on which the statistical calculations were based. In addition, dissolved-solids data are examined by...
Geologic and well-construction data for the H-10 borehole complex near the proposed Waste Isolation Pilot Plant site, southeastern New Mexico
J.G. Wells, S.L. Drellack
1983, Water-Resources Investigations Report 83-4124
The H-10 borehole complex, a group of three closely spaced boreholes, is located 3 1/2 miles southeast of the proposed Waste Isolation Pilot Plant site in west-central Lea County, New Mexico. The geological data presented in this report are part of a site-characterization study for the possible storage of defense-associated...
Geology and resources of the Andersonville, Georgia, kaolin and bauxite district
Harland E. Cofer, John Phillip Manker
1983, Open-File Report 83-580
The kaolin and kaolin-rich sediments of the Andersonville district were deposited in an estuary environment with restricted circulation and little tidal or longshore current influence. Micaceous kaolinitic clays were deposited during late Paleocene time on broad, shallow water flats between deeper water distributary channels in the estuarine system. During the...
Mineral surveys by the Geological Survey and the Bureau of Mines of Bureau of Land Management Wilderness Study Areas
Helen M. Beikman, Margaret Hinkle, Twila Frieders, Susan M. Marcus, James R. Edward
1983, Circular 901
The Federal Land Policy and Management Act of 1976 instructed the Bureau of Land Management (BLM) to review all public lands under its jurisdiction and to determine their suitability or nonsuitability for wilderness designation. As part of this process, the Geological Survey and the Bureau of Mines conduct mineral surveys...
