Techniques for collecting and handling increment tree cores are described. Procedures include those for cleaning and caring for increment borers, extracting the sample from a tree, core surfacing, crossdating, and measuring. (USGS)...
Potentiometric surface of the upper Floridan Aquifer in the St. Johns River Water Management District and vicinity, Florida, May 1985
George R. Schiner, Eugene C. Hayes
1985, Open-File Report 85-491
This map shows the potentiometric surface of the Upper Floridan aquifer in the St. Johns River Water Management District and vicinity for May 1985. The Upper Floridan aquifer is the principal source of potable water in the area. Water-level measurements were made on approximately 1,000 wells and on several springs....
Water Resources Data for California, Water Year 1984; Volume 2. Pacific Slope Basins from Arroyo Grande to Oregon State Line except Central Valley
S. Anderson, K.L. Markham, V. Piro, W.F. Shelton, D.A. Grillo
1985, Water Data Report CA-84-2
Water resources data for the 1984 water year for California consists of records of stage, discharge, and water quality of streams; stage and contents in lakes and reservoirs; and water levels and water quality in wells. Volume 2 contains discharge records for 132 gaging stations; stage and contents for 18...
Water Resources Data for California, Water Year 1983, Volume 4. Northern California Valley Basins and the Great Basin from Honey Lake Basin to Oregon State Line
R. P. Fogelman, J.R. Mullen, W.F. Shelton, R.G. Simpson, D.A. Grillo
1985, Water Data Report CA-83-4
Water-resources data for the 1983 water year for California consists of records of stage, discharge, and water quality of streams; stage and contents in lakes and reservoirs; and water levels and water quality in wells. Volume 4 contains discharge records for 153 gaging stations; stage and contents for 25 lakes...
Quantity and quality of storm runoff in the Irondequoit Creek basin near Rochester, New York; Part 1. Data-collection network and methods, quality-assurance program, and description of available data
Philip J. Zarriello, W. E. Harding, R. M. Yager, W. M. Kappel
1985, Open-File Report 84-610
A 14-month data collection program of quantity and quality of storm precipitation and runoff was conducted in the Irondequoit Creek basin, a 438-sq km area along the south shore of Lake Ontario in north-central New York, from July 1980 through August 1981. The data from a basis for study of...
Water resources data, Texas, water year 1984; Volume 2. San Jacinto River basin, Brazos River basin, San Bernard River basin, and intervening coastal basins
H.D. Buckner, E.R. Carrillo, H.J. Davidson
1985, Water Data Report TX-84-2
Surface-water data for the 1984 water year for Texas are presented in three volumes, appropriately identified as to content by river basins. Data in each volume consist of records of stage, discharge, and water quality of streams and canals; and stage, contents, and water quality of lakes and reservoirs. Also...
An approach for appraising the accuracy of suspended-sediment data
D. E. Burkham
1985, Professional Paper 1333
Procedures are presented for appraising the accuracy of suspended-sediment data. Types of errors involved are sampling error, spatial error, temporal error, and sediment-discharge error. The standard error of estimate is used to represent errors. Suspended-sediment data for 17 U.S. Geological Survey gaging stations in Arizona, California, Nebraska, New Mexico, Pennsylvania,...
Preliminary map showing the difference between the potentiometric surfaces of the Aquia Aquifer of September 1982 and September 1984 in southern Maryland
Frederick K. Mack, Judith C. Wheeler, Stephen E. Curtin, David C. Andreasen
1985, Water-Resources Investigations Report 85-4339
The potentiometric map is highlighted with indications concerning: (1) outcrop areas of the Aquia aquifer; (2) the potentiometric contour of the aquifer; (3) observation and/or supply wells yielding < 10,000 gallons/day (gpd); and (4) other supply wells with yields > 10,000 gpd. (Lantz-PTT)...
Seismic-refraction study of suspected drift-filled bedrock valleys in Ramsey County, Minnesota
D. G. Woodward
1985, Water-Resources Investigations Report 85-4107
Seismic-refraction surveys were made across suspected buried, drift-filled bedrock valleys believed to underlie two sites of known ground-water contamination the Twin Cities Army Ammunition Plant (TCAAP) near New Brighton and the former Koppers Coke Plant in St. Paul, Ramsey County, Minnesota. Refraction data were collected along two lines at each...
Mineral resource potential map of the Fossil Ridge Wilderness Study Area, Gunnison County, Colorado
Ed DeWitt, R. J. Stoneman, J. R. Clark, S.E. Kluender
1985, Miscellaneous Field Studies Map 1629-A
Parts of the Fossil Ridge Wilderness Study Area have a high resource potential for gold and silver in small deposits, uranium in medium-size deposits, and high-calcium limestone in large deposits. Parts have a moderate to high potential for uranium, thorium, and light rare-earth elements in small- to medium-size deposits, a...
