Chemical quality of Michigan streams
Warren W. Wood
1970, Circular 634
Concentrations of chemical constituents of Michigan streams exhibit regional patterns that are primarily a function of geology and evapotranspiration. However, in some areas waste disposal by municipal and industrial organizations has altered the natural distribution and concentrations of dissolved material. Concentration and areal distribution of chemical constitutents were found to...
Geologic log and chemical data, diamond drill hole 1, Samrah, Kingdom of Saudi Arabia
P. K. Theobald Jr., Charles E. Thompson, Henry D. Horn
1970, Open-File Report 70-324
Diamond drill hole number 1 at the Samrah ancient mine, Kingdom of Saudi Arabia penetrated a series of mineralized fractures. Lead, zinc, and silver are the principal ore metals and galena and sphalerito are the ore minerals identified to date. Throughout the core there is a somewhat better correlation of...
Streamflow in the upper Santa Cruz River basin, Santa Cruz and Pima Counties, Arizona
Alberto Condes de la Torre
1970, Water Supply Paper 1939-A
Streamflow records obtained in the upper Santa Cruz River basin of southern Arizona, United States, and northern Sonora, Mexico, have been analyzed to aid in the appraisal of the surface-water resources of the area. Records are available for 15 sites, and the length of record ranges from 60 years for...
Accoustical survey of Massachusetts and Cape Cod Bays, western Gulf of Maine
Brian E. Tucholke, Robert N. Oldale, C. D. Hollister
1970, Open-File Report 70-331
The accompanying map shows the amount of acoustic penetration achieved in the sediments of the western Gulf of Maine using a 3.5 kHz echo sounding system and illustrates the pronounced control of topography on sediment distribution. Little or no sub-bottom penetration was observed in areas of sand and gravel on...
Feasibility of surveying pesticide coverage with airborne fluorometer
George Eimert Stoertz, William R. Hemphill
1970, Open-File Report 70-315
Response of a Fraunhofer line discriminator (FLD) to varying distributions of granulated corncobs stained with varying concentrations of Rhodamine WT dye was tested on the ground and from an H-19 helicopter. By design the instrument detected fluorescence specifically at the sodium D2 Fraunhofer line (5890 angstroms). The granules are used...
Environments at U.S. and U.S.S.R. nuclear explosion sites petroleum-stimulation projects
Maurice J. Terman
1970, Open-File Report 71-279
The United States Plowshare program for the peaceful application of nuclear explosives was formally established by the Atomic Energy Commission in 1957. A number of engineering uses for such explosions were proposed and discussed in the late fifties, mostly by personnel of the Lawrence Radiation Laboratory under contract to AEC,...
