Leaching characteristics of ash from the May 18, 1980, eruption of Mount St. Helens Volcano, Washington
David Burl Smith, Robert A. Zielinski, Howard E. Taylor
1982, Open-File Report 82-987
Leaching of freshly erupted air-fall ash, unaffected by rain, from the May 18, 1.980,eruption of Mount St. Helens volcano, Washington, shows that Ca 2+, Na+, Mg+, SO4 2-, and Cl- are the predominant chemical species released on first exposure of the ash to water. Extremely high correlation of Ca with...
Water-soluble material on aerosols collected within volcanic eruption clouds

1982, Journal of Geophysical Research - Oceans (87) 4963-4972
In February and March of 1978, filter samplers mounted on an aircraft were used to collect the aerosol fraction of the eruption clouds from three active Guatemalan volcanoes (Fuego, Pacaya, and Santiaguito). The samples were collected on Teflon (Fluoropore) filters with a nominal pore diameter of 0.5μm. The mass of...
Leachability of uranium and other elements from freshly erupted volcanic ash
D. B. Smith, R. A. Zielinski, W.I. Rose Jr.
1982, Journal of Volcanology and Geothermal Research (13) 1-30
A study of leaching of freshly erupted basaltic and dacitic air-fall ash and bomb fragment samples, unaffected by rain, shows that glass dissolution is the dominant process by which uranium is initially mobilized from air-fall volcanic ash. Si, Li, and V are also preferentially mobilized by glass dissolution. Gaseous transfer...
Common tern colonies along the mid-Atlantic coast. I. Nestling chronology

1. Sixteen Common Tern colonies in Rhode Island, New Jersey, Virginia, and North Carolina were studied from May through July 1980 by four investigators. Nests were marked during egg laying and were monitored every 5-7 days until fledging of young. 2. Results from 1980 indicate that ambient temperature differences...

A study of leaching of freshly erupted basaltic and dacitic air-fall ash and bomb fragment samples, unaffected by rain, shows that glass dissolution is the dominant orocess by which uranium is initially mobilized from air-fall volcanic ash. Si, Li, and V are also Preferentially mobilized by glass dissolution. Gaseous transfer...
Instrument specifications and geophysical records for airborne electromagnetic survey of parts of Iron, Baraga, and Dickson Counties, Michigan
William D. Heran, Bruce D. Smith
1980, Open-File Report 80-296
The data presented herein is from an airborne electromagnetic INPUT* survey conducted by Geoterrex Limited of Canada for the U.S. Geological Survey. The survey area is located in the central part of the Upper Peninsula of Michigan, within parts of Iron, Baraga, and Dickinson Counties. The general area covered is...

Analysis of borehole geophysical information across a uranium deposit in the Jackson Group, Karnes County, Texas
Jeffrey J. Daniels, James Henry Scott, Bruce D. Smith
1979, Open-File Report 79-585
Borehole geophysical studies across a uranium deposit in the Jackson Group, South Texas, show the three geochemical environments often associated with uranium roll-type deposits: an altered (oxidized) zone, an ore zone, and an unaltered (reduced) zone. Mineralogic analysis of the total sulfides contained in the drill core shows only slight...

Principal facts for borehole gravity stations in wells DC-3, DC-5, and DC-7 at the Hanford Site, Washington, and in well RSH No. 1 on Rattlesnake Hills, Washington
S. L. Robbins, R.J. Martinez, D.L. Smith
1979, Open-File Report 79-849
Borehole gravity surveys were carried out in four wells in the State of Washington by the U.S. Geological Survey (U.S.G.S.) in September and October of 1978 using the U.S.G.S. - LaCoste and Romberg borehole gravity meter G-95 (BHGM) (McCulloh and others, 1967a; McCulloh and others, 1967b). The primary objective of...
The flow mechanism in the Chalk based on radio-isotope analyses of groundwater in the London Basin
R.A. Downing, F.J. Pearson, D. B. Smith
1979, Journal of Hydrology (40) 67-83
14C analyses of groundwaters from the Chalk of the London Basin are re-interpreted and the age of the groundwater is revised. Radio-isotope analyses are used to examine the flow mechanism in the aquifer. The evidence supports the view that a network of micro-fissures and larger intergranular pores in the matrix...
Mortality of experimentally descaled smolts of coho salmon (Oncorhynchus kisutch) in fresh and salt water
Gerald R. Bouck, Stanley D. Smith
1979, Transactions of the American Fisheries Society (108) 67-69
Removal of slime from 25% of the body caused no deaths among smolts of coho salmon in fresh water or in seawater (28‰). Removal of slime and scales from the same percentage of body area caused no deaths in fresh water, but 75% mortality within 10 days in seawater. The...

The age of groundwater in the Lincolnshire Limestone, England and its relevance to the flow mechanism
R.A. Downing, D. B. Smith, F.J. Pearson, R.A. Monkhouse, R.L. Otlet
1977, Journal of Hydrology (33) 201-216
Groundwater samples from the Lincolnshire Limestone have been analysed for tritium, radiocarbon, and the stable-isotope ratios 13C12C">13C12C, 18O16O">18O16O and D/H. The age of the water increases in a downgradient direction below overlying confining deposits and reaches a maximum age greater than...
