Changes in the organic material in lakes in the blast zone of Mount St. Helens, Washington
Diane M. McKnight, John M. Klein, Robert C. Wissman
1984, Circular 850-L
During several periods of volcanic-ash eruption at Mount St. Helens, Wash., (March 30, May 25-26, May 30-June 2, and June 12-13, 1980) strong winds from the north occurred at high altitudes. As a result, the volcanic ash fell some 50 miles to the south in the Bull Run watershed, the...

Discharge ratings at gaging stations
E.J. Kennedy
1984, Techniques of Water-Resources Investigations 03-A10
A discharge rating is the relation of the discharge at a gaging station to stage and sometimes also to other variables. This chapter of 'Techniques of Water-Resources Investigations' describes the procedures commonly used to develop simple ratings where discharge is related only to stage and the most frequently encountered types...
Earth and water resources and hazards in Central America
Charles G. Cunningham, R.W. Fary, Marianne Guffanti, Della Laura, M. P. Lee, C.D. Masters, R. L. Miller, Ferdinand Quinones-Marquez, R.W. Peebles, J.A. Reinemund, D. P. Russ
1984, Circular 925
Long-range economic development in Central America will depend in large part on production of indigenous mineral, energy, and water resources and on mitigation of the disastrous effects of geologic and hydrologic hazards such as landslides, earthquakes, volcanic eruptions, and floods. The region has six world-class metal mines at present as...

L. J. Slack, S. P. Blumer
1984, Open-File Report 84-446
Water at 102 sites in 59 coal-mine ponds in eastern Oklahoma was sampled at lease twice during June to November 1977-81 to determine temperature, specific conductance, dissolved oxygen, pH, and dissolved sulfate, chloride, iron, and manganese--as part of a study of the hydrology of the Oklahoma coalfield. These determinations show...

Principal facts for gravity stations in Dixie; Fairview, and Stingaree valleys, Churchill and Pershing counties, Nevada
D. H. Schaefer, J. M. Thomas, B.G. Duffrin
1984, Open-File Report 84-586
During March through July 1979, gravity measurements were made at 300 stations in Dixie Valley, Nevada. In December 1981, 45 additional stations were added--7 in Dixie Valley, 23 in Fairview Valley, and 15 in Stingaree Valley. Most altitudes were determined by using altimeters or topographic maps. The gravity observations were...

1984, Open-File Report 84-439
A study was conducted to evaluate water-resources problems related to abandoned lead and zinc mines in Cherokee County, Kansas, and adjacent areas in Missouri and Oklahoma. Past mining activities have caused changes in the hydrogeology of the area. Lead and zinc mining has caused discontinuities and perforations in the confining...

Rhyolitic rocks were erupted from vents in and adjacent to the Owyhee Mountains and Owyhee Plateau of southwestern Idaho from 16 m.y. ago to about 10 m.y. ago. They were deposited on a highly irregular surface developed on a variety of basement rocks that include granitic rocks of Cretaceous age,...
The concept of electron activity and its relation to redox potentials in aqueous geochemical systems
D.C. Thorstenson
1984, Open-File Report 84-72
The definition of a formal thermodynamic activity of electrons in redox reactions appears in the literature of the 1920's. The concept of pe as -log (electron activity) was introduced by Jorgensen in 1945 and popularized in the geochemical literature by Sillen, who considered pe and pH as master variables in...
