Map projections used by the U.S. Geological Survey
John Parr Snyder
1982, Bulletin 1532
After decades of using only one map projection, the Polyconic, for its mapping program, the U.S. Geological Survey (USGS) now uses sixteen of the more comnon map projections for its published maps. For larger scale maps, including topographic quadrangles and the State Base Map Series, conformal projections such as the...
Saturated thickness of the High Plains regional aquifer in 1980, northwestern Oklahoma
John S. Havens
1982, Open-File Report 82-760
During 1978, the U.S. Geological Survey began a 5-year study of the High Plains regional aquifer system to provide hydrologic information for evaluation of the effects of long-term development of the aquifer and to develop computer models for prediction of aquifer response to alternative changes in ground-water management (Weeks, 1978)....
Ground-water levels in selected well fields and in west-central Florida, September 1981
D. K. Yobbi, G. L. Barr
1982, Open-File Report 82-261
The water table in the surficial aquifer and the potentiometric surface of the Floridan aquifer in a 1,200-square-mile area in west-central Florida are mapped semiannually by the U.S. Geological Survey. Maps are based on water levels measured in wells each May to coincide with seasonal low levels and each September...
Habitat Suitability Index Models: Common carp
Elizabeth A. Edwards, Katie Twomey
1982, FWS/OBS 82/10.12
The common carp (Cyprinus carpio) is a native of Asia. It is now found on every continent except Antarctica (Jester 1974) and in all 48 contiguous States (Sigler 1958). The northern limit to carp distribution appears to be the 18° C isotherm (Keleher 1956). The common carp hybridizes in nature...
Acoustic systems for the measurement of streamflow
Antonius Laenen, Winchell Smith
1982, Open-File Report 82-329
Very little information is available concerning acoustic velocity meter (AVM) operation, performance, and limitations. This report provides a better understanding about the application of AVM instrumentation to streamflow measurment. Operational U.S. Geological Survey systems have proven that AVM equipment is accurate and dependable. AVM equipment has no practical upper limit...
Flood of October 8, 1977 in St. Croix, U.S. Virgin Islands
Karl G. Johnson, Ramon A. Carrasquillo, Ralph Gonzalez
1982, Open-File Report 82-262
Severe flooding throughout St. Croix, United States Virgin Islands occurred on October 8, 1977. A tropical storm moving across the island produced as much as 16 inches of precipitation. The most affected areas were near Frederiksted, Mon Bijou, and the Airport. The peak discharge of River Gut near the Airport...
Habitat Suitability Index Models: Marten
Arthur W. Allen
1982, FWS/OBS 82/10.11
Habitat preferences and species characteristics of the pine marten (Martes americana) 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 species-habitat requirements of the pine marten. Habitat use information is...
Water resources data Georgia, water year 1981
Water Resources Division, U.S. Geological Survey
1982, Water Data Report GA-81-1
Water resources data for the 1981 water year for Georgia consists of records of stage, discharge, and water quality of streams; stage and contents of lakes and reservoirs; and ground-water levels. This report contains discharge records of 109 gaging stations; stage for 10 gaging stations; stage and contents for 17...
Habitat Suitability Index Models: Ferruginous hawk
Thomas M. Jasikoff
1982, FWS/OBS 82/10.10
The ferruginous hawk inhabits grasslands, shrublands, and steppe-deserts of the Western United States. It is a common nester in Colorado, Idaho, Montana, Utah, and Wyoming (Call 1978). Populations in the more Northern States tend to be migratory, spending the winter in New Mexico, Colorado, Kansas, Texas, and Oklahoma (Call 1979).Ferruginous...
