Detection of diethylnitrosamine in nitrate-rich water following treatment with Rhodamine flow tracers
S. L. Abidi
1982, Water Research (16) 199-204
Extremely carcinogenic diethylnitrosamine (DENA) was found to form in up to 75% yield from the reaction of nitrite with the two commonly used water tracing dyes. Rhodamine B and Rhodamine WT, DENA was detected at trace levels (0.13–7.02 μg −1) in river water samples after treatment with the dye and nitrite....
USGS aerial resolution targets.
P.H. Salamonowicz
1982, Photogrammetric Engineering and Remote Sensing (48) 1469-1473
It is necessary to measure the achievable resolution of any airborne sensor that is to be used for metric purposes. Laboratory calibration facilities may be inadequate or inappropriate for determining the resolution of non-photographic sensors such as optical-mechanical scanners, television imaging tubes, and linear arrays. However, large target arrays imaged...

Deserts of China
Alta S. Walker
1982, American Scientist (70) 366-376
Improving arid land quality requires an understanding of the original state of the land and its relationship to wind, water, and plant regimes, as well as understanding of interactions within the present ecosystem. Chinese scientists and local residents have made significant advances in improving arid environments in gobi and sandy...
Changes in vegetation and grazing capacity following honey mesquite control
Kirk C. McDaniel, John H. Brock, Robert H. Haas
1982, Journal of Range Management (35) 551-557
Honey mesquite kill and suppression, vegetation response, and changes in grazing use and capacity were evaluated following brush control in north-central Texas. Tree grubbing was most effective for eliminating honey mesquite, but because of soil and plant damage the treatment did not increase grazing capacity or improve range condition compared...
An assessment of Landsat data acquisition history on identification and area estimation of corn and soybeans
M. M. Hixson, M. E. Bauer, Donna K. Scholz
1982, Remote Sensing of Environment (12) 123-128
In the past decade, numerous studies have demonstrated the potential of satellite remote sensing for providing accurate timely crop area information. This study assessed the impact of Landsat data acquisition history on classification and area estimation accuracy of corn and soybeans in the U.S. Corn Belt. The results illustrate the...
Oahu: perspective from space
Gary E. Johnson
1982, Journal of Geography (81) 30-32
Satellite remote sensing provides us with a unique perspective from space. This perspective is synoptic in nature and provides regional views of most of the land areas of the earth. The orbital characteristics of the Landsat system are such that repetitive imagery of the same area may be obtained. Because...
Evaluating the crop coefficient using spectral reflectance
J. L. Heilman, W. E. Heilman, Donald G. Moore
1982, Agronomy Journal (74) 967-971
A field study was conducted in four differentially irrigated plots of alfalfa (Medicago sativa L.) planted in Shiprock sandy loam (coarseloamy, mixed, mesic Typic Haplargid) to assess spectral reflectance for estimating the crop coefficient (Kc), defined here as the ratio of actual to potential evapotranspiration (ET). A bidirectional reflectance factor was...
Beatty, Nevada: A section in U.S. Geological Survey research in radioactive waste disposal - Fiscal year 1979 (Circular 847)

Robert Schneider, E.H. Roseboom, J.B. Robertson, P. R. Stevens, editor(s)
1982, Report, U.S. Geological Survey research in radioactive waste disposal - Fiscal year 1979 (Circular 847)
A commercial low-level radioactive waste disposal site has been operating near Beatty, Nevada, about 150 km northwest of Las Vegas, since 1962. The 32-ha site is situated in a desolate region of the Amargosa River Valley, sometimes referred to as the Amargosa Desert. Average annual precipitation is only about 114...
Impact of Mount St. Helens eruption on hydrology and water quality
J. E. Bonelli, Howard E. Taylor, J.M. Klein
1982, Technical Report N-8311538
The 1980 eruptions of Mount St. Helens in southeast Washington resulted in a pronounced effect on the surface and ground water resources of the state. In response to the volcanic activity, the U.S. Geological Survey intensified statewide surface and ground water sampling programs to determine the nature and magnitude of...

Hydrology of Wisconsin wetlands
R.P. Novitzki
1982, Wisconsin Geological & Natural History Survey Information Circular 40
Data from 15 wetland study sites, supplemented by data from reconnaissance visits to 219 additional wetlands, were used to describe the hydrologic characteristics of Wisconsin wetlands and to suggest a simple hydrologic classification system. Wisconsin's wetlands OCCUf in depressions and on slopes. They may be in contact with ground water...
Relation between freshwater flow and salinity distributions in the Alafia River, Bullfrog Creek, and Hillsborough Bay, Florida
R.F. Giovannelli, Southwest Florida Water Management District.
1981, Water-Resources Investigations Report 80-102
Data on streamflow, tide stage, specific conductance, and chloride concentration were collected in the Alafia River and Bullfrog Creek to describe the salinity and physical characteristics of the saltwater wedge. The location of the saltwater-freshwater interface for both streams was described by multiple regression equations involving streamflow and tide stage....
