Martian volcanism: Additional observations and evidence for pyroclastic activity
M. West
1974, Icarus (21) 1-11
Inspection of the Mariner 9 B-camera (resolution 100–200m) and A-camera (resolution 1–2km) photographs of Mars reveals numerous analogs of terrestrial and lunar volcanic features. In addition to the exceptionally large constructional features in the Tharsis region, many other large and small landforms present...
Progress report on flood magnitude and frequency of Vermont streams
Carl G. Johnson, Gary D. Tasker
1974, Open-File Report 74-130
A technique is presented for estimating the magnitude and frequency of floods on streams in Vermont with drainage areas between 0.27 and 1,040 square miles. Multiple-regression techniques are used to define the relation between flood peaks, collected at a network of gaging stations maintained by the U.S. Geological Survey, and...
The chemical composition and estimated minimum thermal reservoir temperatures of the principal hot springs of northern and central Nevada
Robert H. Mariner, J. B. Rapp, L.M. Willey, T. S. Presser
1974, Open-File Report 74-1066
Fifty-five of the principal hot springs in northern and central Nevada have been sampled for chemical analyses. Major element constituents, sodium, potassium, calcium, and silica suggest minimum thermal-aquifer temperatures of 140°C or more at 16 of the hot spring complexes. At least five of the hot springs issue mixed waters...

An attempt to age mallards using eye lens proteins
Charles J. Henny, J. Larry Ludke
1974, Journal of Wildlife Management (38) 138-141
An analysis of insoluble protein content of eye lenses from 59 known-age mallards (Anas platyrhynchos) indicated a slight increase between 8-9 months and 7 years of age. Nearly a complete overlapping of the insoluble protein content of individuals of different ages was apparent showing that the technique cannot be used...
U-Th-Pb and Rb-Sr systematics of Apollo 17 boulder 7 from the North Massif of the Taurus-Littrow Valley
P.D. Nunes, M. Tatsumoto, D.M. Unruh
1974, Earth and Planetary Science Letters (23) 445-452
Portions of highland breccia boulder 7 collected during the Apollo 17 mission were studied using UThPb and RbSr systematics. A RbSr internal isochron age of3.89 ± 0.08b.y. with an initial87Sr/86Sr of0.69926 ± 0.00008 was obtained for...
Residues of DDT in lake trout (Salvelinus namaycush) and coho salmon (Oncorhynchus kisutch) from the Great Lakes
Robert E. Reinert, Harold L. Bergman
1974, Journal of the Fisheries Research Board of Canada (31) 191-199
Concentrations of DDT residues were higher in lake trout (Salvelinus namaycush) from southern Lake Michigan in 1966–70 (average 18.1 ppm in fish 558–684 mm long) than in lake trout of the same size-class from Lake Superior in 1968–69 (4.4 ppm), and higher in adult coho salmon (Oncorhynchus kisutch) from Lake Michigan in 1968–71...
Various fish species as biological control agents for the dark rice field mosquito in Arkansas rice fields
R. B. Davey, M. V. Meisch, D. L. Gray, J. M. Martin, Kermit E. Sneed, F. J. Williams
1974, Environmental Entomology (3) 823-826
During the summers of 1972–73, 10 fish species were evaluated as predators against larvae of the dark rice field mosquito, Psorophora confinnis (Lynch-Arribalzaga), near Stuttgart, Ark. Stocking rates were 0.02, 0.03, and 0.06 fish/ft 2 . At the lowest stocking rate green sunfish, Lepomis cyanellus Rafinesque, reduced larval numbers by 89.7% and were significantly more effective...
Hydrologic data for Pin Oak Creek, Trinity River Basin, Texas, 1972
B.B. Hampton
1974, Report
The U.S. Soil Conservation Service is actively engaged in the installation of flood- and soil-erosion reducing measures in Texas under the authority of "The Flood Control Act of 1936 and 1944" and "Watershed Protection and Flood Prevention Act" (Public Law 566), as amended. The Soil Conservation Service has found a...
Problems encountered in the use of neutron methods for elemental analysis on planetary surfaces
F. Senftle, P. Philbin, R. Moxham, G. Boynton, J. Trombka
1974, Nuclear Instruments and Methods (117) 435-443
From experimental studies of gamma rays from fast and thermal neutron reactions in hydrogeneous and non-hydrogeneous, semi-infinite samples and from Monte Carlo calculations on soil of a composition which might typically be encountered on planetary surfaces, it is found that gamma rays from...
A solvent extraction study of molybdenum chloride and molybdenum thiocyanate complexes
L. P. Greenland, E.G. Lillie
1974, Analytica Chimica Acta (69) 335-346
The effect of reducing agents on molybdenum(VI) solutions in hydrochloric acid was studied by a solvent extraction technique to elucidate the composition of the colored molybdenum thiocyanate complex. Neither copper(I) chloride nor ascorbic acid have any effect on the extraction of MoO2Cl2; it is inferred...
Geophysical evidence for the intersection of the St Paul, Cape Palmas and Grand Cess fracture zones with the continental margin of Liberia, West Africa
John C. Behrendt, J. Schlee, James M. Robb
1974, Nature (248) 324-326
PUBLISHED reconstructions of Gondwana continent1 (Fig. la) show a gap in fit near the junction of the Americas and Africa. To study this critical area, the Unitedgeo I made geophysical measurements and collected rock samples across the continental margin of Liberia (USGS-IDOE cruise leg 5) in November...
Scientists probe Earth’s secrets at the Hawaiian Volcano Observatory
J. D. Unger

The Hawaiian Volcano Observatory (HVO) sits on the edge of Kilauea Caldera at the summit of Kilauea Volcao, one of the five volcanoes on the island of Hawaii, the largest island in the Hawaiian Islands chain. Of the five, only Kilauea and Mauna Loa have been active in the past...
Erosion by catastrophic floods on Mars and Earth
V.R. Baker, D.J. Milton
1974, Icarus (23) 27-41
The large Martian channels, especially Kasei, Ares, Tiu, Simud, and Mangala Valles, show morphologic features strikingly similar to those of the Channeled Scabland of eastern Washington, produced by the catastrophic breakout floods of Pleistocene Lake Missoula. Features in the overall pattern include the...

A number of significant earthquakes happened during the last 2 months of 1973. Two major earthquakes (magnitude 7.0-7.9) occurred in the New Hebrides Islands, bringing the final major earthquake total for the year to 11, somewhat below the annual average which is 18. One great earthquake (magntidue 8.0 and above)...

The California geodimeter network; measuring movement along the San Andreas Fault
J.C. Savage
1974, Earthquake Information Bulletin (USGS) (6) 3-7
Following the great California earthquake of 1906 H. F. Reid, a contemporary seismologist, proposed the elastic rebound theory which in effect says that earthquake potential arises from the accumulation of elastic strain within the Earth's crust, just as the stretching of a rubberband creates the potential for violent rebound upon...
