Mineral exploration and soil analysis using in situ neutron activation
F. E. Senftle, A.F. Hoyte
1966, Nuclear Instruments and Methods (42) 93-103
A feasibility study has been made to operate by remote control an unshielded portable positive-ion accelerator type neutron source to induce activities in the ground or rock by “in situ” neutron irradiation. Selective activation techniques make it possible to detect some thirty or...
Uptake of 2,4-dichlorophenoxyacetic acid by Pseudomonas fluorescens
Gary Wedemeyer
1966, Applied and Environmental Microbiology (14) 486-491
Factors influencing the uptake of the sodium salt of 2,4-dichlorophenoxyacetic acid (2,4-D), under conditions in which no net metabolism occurred, were investigated in an effort to determine both the significance of “non-metabolic” uptake as a potential agent in reducing pesticide levels and the mechanisms involved. Uptake of 2,4-D was affected...
Waste injection into a deep limestone in northwestern Florida
J.T. Barraclough
1966, Groundwater (4) 22-24
During a three-month trial period, 70 million gallons of industrial wastes were successfully injected at moderate pressures into a deep limestone in the westernmost part of Florida. The movement of these wastes is expected to be predominantly southward toward the natural discharge area which is presumed to be far out...
A sampler for coring sediments in rivers and estuaries
Edmund A. Prych, D. W. Hubbell
1966, Geological Society of America Bulletin (77) 549-556
A portable sampler developed to core submerged unconsolidated sediments collects cores that are 180 cm long and 4.75cm in diameter. The sampler is used from a 12-m boat in water depths up to 20 m and in flow velocities up to 1.5m per second to sample river and estuarine deposits...
Glacier mass budget measurements by hydrologic means
Wendell V. Tangborn
1966, Water Resources Research (2) 105-110
Ice storage changes for the South Cascade Glacier drainage basin were determined for the 1957–1964 period using basin runoff and precipitation measurements. Measurements indicate that evaporation and condensation are negligible compared with the large runoff and precipitation values. Runoff, measured by a stream discharge station, averaged 4.04 m/yr; precipitation, determined...
Some effects of Heptachlor on bluegills (Lepomis macrochirus)
Austin K. Andrews, Bruce E. Stebbings, Charles C. Van Valin
1966, Transactions of the American Fisheries Society (95) 297-309
In complementary studies of the chronic effects of heptachlor on bluegills, four similar earthen ponds were treated once with different concentrations of heptachlor, and the fish in six plastic pools were routinely fed different levels of heptachlor. A fifth pond and two plastic pools were used as controls. Higher dosages...
Preparation of dart tags for use in the field
Joseph R. Higham
1966, Progressive Fish-Culturist (28) 205
Tagging in the field requires an efficient method of preparing the tags for dispensation under a wide range of conditions. The method described here was very efficient in an extensive tagging program on Oahe Reservoir, South Dakota....
Some alkali and titania analyses of tektites before and after G-1 precision monitoring
D.B. Tatlock
1966, Geochimica et Cosmochimica Acta (30) 123-128
A comparison of 55 older analyses of Australasian tektites with 110 modern precisely monitored analyses suggests that more than half of the older alkali and titania determinations are decidedly inaccurate and misleading. Deviations of the older analyses from the restricted values of the...
Crystallization of tholeiitic basalt in Alae Lava Lake, Hawaii
D. L. Peck, T. L. Wright, J.G. Moore
1966, Bulletin Volcanologique (29) 629-655
The eruption of Kilauea Volcano August 21–23, 1963, left 600,000 cubic meters of basaltic lava in a lava lake as much as 15 meters deep in Alae pit crater. Field studies of the lake began August 27 and include repeated core drilling, measurements of temperature in the crust and melt,...
Some Debye temperatures from single-crystal elastic constant data
R. A. Robie, J.L. Edwards
1966, Journal of Applied Physics (37) 2659-2663
The mean velocity of sound has been calculated for 14 crystalline solids by using the best recent values of their single‐crystal elastic stiffness constants. These mean sound velocities have been used to obtain the elastic Debye temperatures θDe for these materials. Models of the three wave velocity surfaces for calcite are illustrated....
Surface water records of Missouri, 1964
1966, Water Data Report MO-64-1
The quality-of-water investigations of the U.S. Geological Survey are concerned with the chemical and physical characteristics of surface and ground water supplies of the Nation. The basic records for the 1964 water year for quality of surface waters within the State of Missouri are given in this report. The data...
The Alaska earthquake, March 27, 1964: regional effects
David S. McCulloch, Samuel J. Tuthill, Wilson M. Laird, J. E. Case, D.F. Barnes, George Plafker, S. L. Robbins, Reuben Kachadoorian, Oscar J. Ferrians Jr., Helen L. Foster, Thor N. V. Karlstrom, M. J. Kirkby, Anne V. Kirkby, Kirk W. Stanley
1966, Professional Paper 543
This is the third in a series of six reports that the U.S. Geological Survey published on the results of a comprehensive geologic study that began, as a reconnaissance survey, within 24 hours after the March 27, 1964, Magnitude 9.2 Great Alaska Earthquake and extended, as detailed investigations, through several...
