Water resources data for Wyoming, water year 1972; part 1, surface water records
Water Resources Division, U.S. Geological Survey
1973, Water Data Report WY-72-1
Surface-water records for the 1972 water year for Wyoming, including records of streamflow or reservoir storage at gaging stations, partial-record stations, and miscellaneous sites, are given in this report. The locations of the gaging stations and partial-record stations are shown in figures 1 and 2. Records for a few pertinent...
Ground-water levels in the United States, 1967-71, north-central States
Water Resources Division, U.S. Geological Survey
1973, Water Supply Paper 2090
Publication of ground-water level data for the United States in watersupply papers was begun by the Geological Survey in 1935. From 1935 through 1939, a single water-supply paper for each year covering the entire Nation was issued (Water-Supply Papers 777, 817, 840, 845, and 886). Since then water-supply papers have...
Water resources data for Wyoming, water year 1972; part 2, water quality records
Water Resources Division, U.S. Geological Survey
1973, Water Data Report WY-72-2
Water-resources data for the 1972 water year for Wyoming include records of data for the chemical and physical characteristics of surface and ground water. Data on the quality of surface water (chemical, temperature, and sediment) were collected from designated sampling sites at predetermined intervals such as once daily, weekly, monthly...
Fractionation and characterization of natural organic matter from certain rivers and soils by free-flow electrophoresis
J.A. Leenheer, Ronald L. Malcolm
1973, Water Supply Paper 1817-E
Soluble river organic matter and soil fulvic acids from a variety of environments were compared by examining the free-flow electrophoretic fractionation curves of organic carbon, color, and polysaccharides. Significant amounts of virtually colorless organic material were found in both the soil and the river preparations. Polysaccharides comprised 20-75 percent of...
Atlas of Mars, Oxia Palus quadrangle, MC-11
United States Geological Survey
1973, Open-File Report 73-330
Th is mosaic is made with computer enhanced Mariner 9 pictures, rectified and scaled to a Mercator projection. Computer processing was performed by the Image Processing Laboratory (IPL) of the Jet Propulsion Laboratory (JPL). Processing included contrast enhancement and high-pass filtering which accentuates topographic features while subduing albedo variations. Photographic...
Atlas of Mars, Amenthes quadrangle, MC-14
United States Geological Survey
1973, Open-File Report 73-331
This mosaic is made with computer enhanced Mariner 9 pictures, rectified and scaled to a Mercator projection. Computer processing was performed by the Image Processing Laboratory (IPL) of the Jet Propulsion Laboratory (JPL). Processing included contrast enhancement and high-pass filtering which accentuates topographic features while subduing albedo variations. Photographic reproductions...
Alas of Mars chart, Mare Tyrrhenum Quadrangle, MC-22
United States Geological Survey
1973, Open-File Report 73-338
This mosaic was made with Mariner 9 pictures provided by the Jet Propulsion Laboratory (JPL), California Institute of Technology. The Image Processing Laboratory (IPL) of JPL processed the digital pictures to remove image artifacts and geometric distortions, to enhance high-frequency topographic detail while subduing low-frequency albedo variation, and to transform...
Atlas of Mars, Iapygia Quadrangle, MC-21
United States Geological Survey
1973, Open-File Report 73-337
This mosaic was made with Mariner 9 pictures provided by the Jet Propulsion Laboratory (JPL), California Institute of Technology. The Image Processing Laboratory (IPL) of JPL processed the digital pictures to remove image artifacts and geometric distortions, to enhance high-frequency topographic detail while subduing low-frequency albedo variation, and to transform...
