1969, Earth and Planetary Science Letters (7) 12-16
Three boreholes have been drilled for the Australian National University near the southeast coast of New South Wales, Australia. The heat flows found are 1.1, 1.0, and 1.3 μcal/cm2sec. The errors resulting from the proximity of the sea and a lake, surface...

1969, Report
An investigation of the water resources of the Colorado part of the San Luis Valley was begun in 1966 by the U.S. Geological Survey, in cooperation with the Colorado Water Conservation Board. (See index map, fig. 1). The purpose of the investigation is to provide information for planning and implementing...
Rearing of sea lamprey, Petromyzon marinus, embryos in distilled water
George W. Piavis, John H. Howell
1969, Copeia (1969) 204-205
Most embryological studies of lampreys in the Great Lakes have been conducted with filtered water from Lake Huron. Although this water was entirely satisfactory for the earlier work, the present need for knowledge of the effects of various compounds on embryological development requires that the initial medium be sterile....

Selective feeding by juvenile diving ducks in summer
James C. Bartonek, J.J. Hickey
1969, The Auk (86) 443-457
Waterfowl often fail to use foods that seem plentiful to the investigator. The extent to which selective feeding or rejection of foods is a function of behavioral and morphological adaptations of the species, conditioned behavior of the individual, or individual preference for certain foods has not been appraised. The objectives...
The rapids and the pools - Grand Canyon: Chapter D in The Colorado River region and John Wesley Powell (Professional Paper 669)
Luna Bergere Leopold
1969, Professional Paper 669-D
Through the Grand Canyon the Colorado drops in elevation about 2,200 feet in 280 miles; most of this drop occurs in rapids that account for only 10 percent of the distance. Despite the importance of rapids, there are no waterfalls. Depth measurements made at 1/10-mile intervals show that the bed...

Sediment Transport in Streams in the Umpqua River Basin, Oregon
C. A. Onions
1969, Report
This report presents tables of suspended-sediment data collected from 1956 to 1967 at 10 sites in the Umpqua River basin. Computations based on these data indicate that average annual suspended-sediment yields at these sites range from 137 to 822 tons per square mile. Because available data for the Umpqua River...

1969, Utah Basic-Data Release 17
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 chiefly by equal contributions of the State of Utah and the Federal Government in accordance with an...
Glaciers and water supply
Mark Meier
1969, Journal American Water Works Association (61) 8-12
Glaciers are one of the few large sources of water supply that remain unexploited. With the advance of civilization into the subpolar regions, a better understanding of glacier hydrology becomes increasingly important....
Rapid determination of filterable residue in natural waters
Herbert E. Allen, Charles W. Bacon
1969, Journal - American Water Works Association (61) 355-356
The most widely used procedures for determining filterable residue (total dissolved solids) in water are macromethods given in Standard Methods. Although macromethods give good results, they require large amounts of water and long drying times. This report describes a microtechnique for determining filterable residue that requires only 0.05...
Insecticides and the Great Lakes
Robert E. Reinert
1969, Limnos (2) 3-9
Cracks in the perfect image of DDT appeared when traces of the insecticide began to show up in a wide variety of organisms throughout the world. As more and more people investigated this problem, it became increasingly evident that terrestrial and aquatic animals were accumulating comparatively high concentrations of...
Selected hydrologic data, southern Utah and Goshen Valleys, Utah
R.M. Cordova
1969, Utah Basic-Data Release 16
The purpose of this report is to present basic geologic, ground-water, surface-water, and quality of water data that are useful for the study and effective development of the water resources of southern Utah and Goshen Valleys. This report supplements an interpretive report which will be published later.Much of the basic...
Saline water in southeastern New Mexico
W. L. Hiss, J.B. Peterson, T.R. Ramsey
1969, Chemical Geology (4) 341-360
Saline waters from formations of several geologic ages are being studied in a seven-county area in southeastern New Mexico and western Texas, where more than 30,000 oil and gas tests have been drilled in the past 40 years. This area of 7,500 sq. miles, which is stratigraphically complex, includes...
Blueschist-facies metamorphism related to regional thrust faulting
M.C. Blake Jr., W. P. Irwin, R. G. Coleman
1969, Tectonophysics (8) 237-246
Rocks of the blueschist (glaucophane schist) facies occur throughout the world in narrow tectonic belts associated with ultramafic rocks. In the Coast Range province of California, blueschist rocks are devloped in the eugeosynclinal Franciscan Formation of Late Mesozoic age. The blueschist rocks form a narrow belt for more than 800...
Geochemistry of pore waters from Shell Oil Company drill holes on the continental slope of the northern Gulf of Mexico
F.T. Manheim, J. L. Bischoff
1969, Chemical Geology (4) 63-82
Pore waters were analyzed from 6 holes drilled from M.V. “Eureka” as a part of the Shell Oil Co. deeper offshore study. The holes were drilled in water depths of 600–3,000 ft. (approximately 180–550 m) and penetrated up to 1,000 ft. (300 m) of Pliocene-Recent clayey sediments. Salt and...
Ion association in natural brines
A.H. Truesdell, B.F. Jones
1969, Chemical Geology (4) 51-62
Natural brines, both surface and subsurface, are highly associated aqueous solutions. Ion complexes in brines may be ion pairs in which the cation remains fully hydrated and the bond between the ions is essentially electrostatic, or coordination complexes in which one or more of the hydration water molecules are...
Use of flooded timber by waterfowl at the Montezuma National Wildlife Refuge
L.M. Cowardin
1969, Journal of Wildlife Management (33) 829-842
Waterfowl use of bottomland hardwood timber stands which were flooded and killed was studied at the Montezuma National Wildlife Refuge, Seneca Falls, New York, from 1962 to 1964. Comparisons of use were made among six habitat types containing dead timber, stumps, and no timber, and with and without emergent vegetation....
Age, growth, and maturity of the longnose sucker Catostomus catostomus, of western Lake Superior
Merryll M. Bailey
1969, Journal of the Fisheries Research Board of Canada (26) 1289-1299
Studies of age, growth, and maturity were based on 1760 fish collected in western Lake Superior in 1964-65. The body:scale relation was curvilinear and the curve had an intercept of 1.65 inches on the length axis. The weight increased as the 2.85 power of the length. Some fish formed an...

Interstitial brines in playa sediments
B.F. Jones, A. S. Van Denburgh, A.H. Truesdell, S.L. Rettig
1969, Chemical Geology (4) 253-262
Study of several closed drainages in the Great Basin has shown that the interstitial solutions of shallow, fine-grained playa deposits store a large quantity of dissolved solids and are often more concentrated than associated lakes and ponds, except in peripheral zones of stream or ground-water inflow. These interstitial fluids,...
The relationship of the rare-earth composition of minerals to geological environment
M. Fleischer, Z. S. Altschuler
1969, Geochimica et Cosmochimica Acta (33) 725-732
It has been known for a long time that the composition of the lanthanides in minerals is controlled to a large degree by crystallo-chemical factors, but is also greatly influenced by changes in geological environment. In general, igneous rocks rich in silica are favourable for the concentration of the heavy...

Compilation of hydrologic data, Green Creek, Brazos River basin, Texas, 1966
Trigg Twichell
1969, Report
In 1950 the U. S. Soil Conservation Service began construction of floodwater-retarding structures in Texas under authorities granted by the Congress. These authorities provide, where economically feasible, that the program be applied to tributary watersheds of 240,000 acres or less. The usual practice has been to control flood runoff from...
