Movement of water in seasonally frozen soil, southeastern North Dakota, 1985-87
D. G. Emerson
1992, Water-Resources Investigations Report 92-4110
A study of seasonally frozen soil was conducted from October 1985 through April 1986 and from October 1986 through April 1987. Three runoff plots were established. On October 30, 1985, 86 mm (millimeters) of water was applied to plot 1, and 43 mm of water was applied to plot 3....
Description and effects of 1988 drought on ground-water levels, streamflow, and reservoir levels in Indiana
K. K. Fowler
1992, Water-Resources Investigations Report 91-4100
Documentation of the 1988 drought in Indiana was undertaken to aid water-management agencies and planners concerned with periods of below-normal precipitation and their effect on commercial, agricultural, and residential water use. Precipitation, temperature, Palmer Drought Severity Indices, and ground- and surface-water levels from water years 1988 and 1989 were compared...
Geohydrologic systems in Kansas physical framework of the western interior plains confining system
R. J. Wolf, Harold E. McGovern, Joseph M. Spinazola
1992, Hydrologic Atlas 722-C
The purpose of this Hydrologic Investigations Atlas is to provide a description of the principal geohydrologic systems in the Upper Cambrian through Lower Cretaceous rocks in Kansas.  This investigation was made as part of the Central Midwest Regional Aquifer-System Analysis (CMRASA). The CMRASA is one of several major investigations by...
Bathymetry at the head of the Cape Fear Slide, offshore North Carolina
Eric A. Schmuck, Peter Popenoe, Charles K. Paull, Carol Brown
1992, Miscellaneous Field Studies Map 2209
The Cape Fear Slide is the largest mass-movement that has been observed on the U.S. Atlantic Margin. It is located off the Carolinas on the continental rise in approximately 1,200-5,500 m water depth and extends downslope for over 300 km (Popenoe, 1982). These maps show the bathymetry at the head...
Methods of analysis by the U. S. Geological Survey National Water Quality Laboratory-Determination of organonitrogen herbicides in water by solid-phase extraction and capillary-column gas chromatography/mass spectrometry with selected-ion monitoring
Mark W. Sandstrom, Duane S. Wydoski, Michael P. Schroeder, Jana L. Zamboni, William T. Foreman
1992, Open-File Report 91-519
A method for the isolation of organonitrogen herbicides from natural water samples using solid-phase extraction and analysis by capillary-column gas chromatography/mass spectrometry with selected-ion monitoring is described. Water samples are filtered to remove suspended particulate matter and then are pumped through disposable solid-phase extraction cartridges containing octadecyl-bonded porous silica to remove the herbicides. The cartridges are...
