Hydrology of limestone terranes in the coastal plain of the Southeastern United States
V. T. Stringfield, H. E. LeGrand
1966, Special Paper of the Geological Society of America (93) 1-46
The very productive limestone aquifers of Tertiary and Quaternary age in the Coastal Plain of the Southeastern States contain a water-table circulation system where aquifers are at or near the land surface; the Tertiary limestone unit is a homoclinal artesian system confined beneath younger beds in coastal areas.The Tertiary limestone...
Bathymetric distribution of fish in the Apostle Islands region, Lake Superior
William R. Dryer
1966, Transactions of the American Fisheries Society (95) 248-259
Records of seasonal and “all-season” (April-December) bathymetric distribution are given for 17 species of fish taken in bottom trawls and experimental gill nets fished on the bottom in 1958–63 in the Apostle Islands region of Lake Superior. The data are based on catches from 578 trawl tows at 2–59 fathoms...
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...
Persistence of 2,6-Dichlorobenzonitrile in aquatic environments
C.C. Van Valin
1966, Book chapter, Organic pesticides in the environment
In two experiments 2,6-dichlorobenzonitrile was added to aquatic systems, and the residue levels were followed for about 6 months. A granular formulation applied to a farm pond at 0.6 p.p.m. produced highest residues in water and fish about 2 weeks following treatment whereas vegetation and soil samples had the highest...
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...
Observed variations in the strontium concentration of sea water
E.E. Angino, G.K. Billings, N. Andersen
1966, Chemical Geology (1) 145-153
On samples obtained from five widely separated areas of the North Atlantic Ocean 91 determinations of strontium were made. These include surface and deep-water samples from both the cold North Atlantic area and the warm subtropical Caribbean area. The results differ from...
Color variations within glacial till, east-central North Dakota--A preliminary investigation
T. E. Kelly, Claud H. Baker Jr.
1966, Journal of Sedimentary Petrology (36) 75-80
Color variations (orange zones within buff-colored till) in drift in east-central North Dakota are believed to represent two tills of separate origin. Mean size, standard deviation, and number and type of pebbles show greater difference between the two tills than do skewness, kurtosis, and partial chemical analyses. Probably blocks of...
Hydrologic and climatologic data, 1965, Salt Lake County, Utah
W.V. Iorns, Reed W. Mower, C. A. Horr
1966, Utah Basic-Data Release 12
An investigation of the water resources of Salt Lake County, Utah, was undertaken by the Water Resources Division of the U.S. Geological Survey in July 1963. This investigation is a cooperative project financed equally by the State of Utah and the Federal Government in accordance with an agreement between the...
Hydrologic and climatologic data collected through 1964, Salt Lake County, Utah
W.V. Iorns, Reed W. Mower, C. A. Horr
1966, Utah Basic-Data Release 11
An investigation of the water resources of Salt Lake County, Utah, was undertaken by the Water Resources Division of the U.S. Geological Survey in July 1963. This investigation is a cooperative project financed equally by the State of Utah and the Federal Government in accordance with an agreement between the...
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...
The tullibee
Stanford H. Smith
1966, Minnesota Conservation Volunteer (29) 49-50
Early explorers and settlers of the northeastern United States and southern Canada found lakes teeming with fish that had white flesh and were good to eat. The larger of these they called whitefish, differentiating two kinds- the lake whitefish and the round or menominee whitefish. These looked much...
Determination of Columbia River flow times from Pasco, Washington using radioactive tracers introduced by the Hanford reactors
Jack L. Nelson, R.W. Perkins, W.L. Haushild
1966, Water Resources Research (2) 31-39
Radioactive tracers introduced into the Columbia River in cooling water from the Hanford reactors were used to measure flow times downstream from Pasco, Washington, as far as Astoria, Oregon. The use of two tracer methods was investigated. One method used the decay of a steady release of Na24 (15-hour half-life)...
