Remote sensing and photogrammetric studies: Part C: comparison between photogrammetric and bistatic-radar slope-frequency distributions
H. J. Moore, G.L. Tyler
1973, Book chapter, Apollo 17 preliminary science report (NASA SP-330)
Stereoscopic photographs taken by the metric and panoramic cameras can be used to obtain information on the roughness and slope-frequency distributions of lunar surfaces (see appendix to this part). Bistatic radar on board Apollo 14, 15, and 16 spacecraft may also be used to obtain information on lunar surface roughness...
Volcanic studies: Part E: Eratosthenian volcanism in Mare Imbrium: source of youngest lava flows
Gerald G. Schaber
1973, Book chapter, Apollo 17 preliminary science report
Orbital photographs taken at low-Sun illumination during both the Apollo 15 (ref. 30-14) and Apollo 17 missions have provided excellent data on the lava flows in the southwestern Mare Imbrium. These photographs have been used recently to present a detailed photogeologic evaluation of these flows and their role in mare...
Hydrogeologic data for the Quinnipiac River basin, Connecticut

1973, Connecticut Water Resources Bulletin 26
This report contains geologic, ground-water, and quality-of-water data collected for the ground-water part of a water-resources inventory of the Quinnipiac River basin, Connecticut. The study was made by the U.S. Geological Survey in fiscal cooperation with the Connecticut Department of Environmental Protection. Collection sites for data used in the study...

Versatile combustion-amalgamation technique for the photometric determination of mercury in fish and environmental samples
Wayne A. Willford, Robert J. Hesselberg, Harold L. Bergman
1973, Journal of the Association of Official Analytical Chemists (56) 1008-1014
Total mercury in a variety of substances is determined rapidly and precisely by direct sample combustion, collection of released mercury by amalgamation, and photometric measurement of mercury volatilized from the heated amalgam. Up to 0.2 g fish tissue is heated in a stream of O2 (1.2 L/min) for 3.5 min in...

Recurrence of seismic migrations along the central California segment of the San Andreas fault system
M.D. Wood, S.S. Allen
1973, Nature (244) 213-215
VERIFICATIONS of tectonic concepts1 concerning seafloor spreading are emerging in a manner that has direct bearing on earthquake prediction. Although the gross pattern of worldwide seismicity contributed to the formulation of the plate tectonic hypothesis, it is the space-time characteristics of this seismicity that may contribute more...
18-Tungstotetracobalto(II)diphosphate and related anions: A novel structural class of heteropolyanions
T.J.R. Weakley, H. T. Evans Jr., J.S. Showell, G.F. Tourne, C.M. Tourne
1973, Journal of the Chemical Society, Chemical Communications 139-140
The P2Co4(H2O)2W 18O6810- anion contains four edge-linked coIIO6 octahedra with coplanar cobalt atoms, in addition to two fragments of the Keggin structure....
A pneumatic sample changer for gamma-ray spectroscopy
C. J. Massoni, R.V. Fones, F.O. Simon
1973, Review of Scientific Instruments (44) 1350-1352
A gravity‐feed, pneumatic‐ejection sample changer has been developed. The changer is suitable for both flat and well‐type detectors and permits the continuous use of gamma‐ray spectroscopy equipment 24 h a day, 7 days a week. The electronic circuitry has a fail‐safe...
Apollo 17 "Orange soil" and meteorite impact on liquid lava
E. Roedder, P.W. Weiblen
1973, Nature (244) 210-212
THE “orange soil” from Shorty Crater differs greatly from ordinary lunar soils in that it consists of ∼99% 10–300 µm smooth shiny spherules and broken fragments of spherules of transparent orange glass, about 20% of which contain partly crystallized to opaque material. The remaining 1 %...
Population dynamics of pond zooplankton, I. Diaptomus pallidus Herrick
K.B. Armitage, B. Saxena, E.E. Angino
1973, Hydrobiologia (42) 295-333
The simultaneous and lag relationships between 27 environmental variables and seven population components of a perennial calanoid copepod were examined by simple and partial correlations and stepwise regression. The analyses consistently explained more than 70% of the variation of a population component. The multiple correlation coefficient (R) usually was highest...
Population dynamics of pond zooplankton II Daphnia ambigua Scourfield
E.E. Angino, K.B. Armitage, B. Saxena
1973, Hydrobiologia (42) 491-507
Calcium was the most important of 27 environmental components affecting density for a 50 week period. Simultaneous stepwise regression accounted for more variability in total number/1 and in the number of ovigerous females/1 than did any of the lag analyses; 1-week lag accounted for the greatest amount of variability in...
A semiobjective method for condensing classifications
F. Demirmen
1973, Journal of the International Association for Mathematical Geology (5) 285-296
A simple, semiobjective method is described to reduce the number of groups in a classification to an arbitrary level without losing contact with the geologic information contained in the evolving groups. The method, operated in a stepwise or cyclic manner, employs some of the commonly used numerical techniques, but avoids...
Thermochemical parameters of minerals from oxygen-buffered hydrothermal equilibrium data: Method, application to annite and almandine
E-An Zen
1973, Contributions to Mineralogy and Petrology (39) 65-80
Reversed univariant hydrothermal phase-equilibrium reactions, in which a redox reaction occurs and is controlled by oxygen buffers, can be used to extract thermochemical data on minerals. The dominant gaseous species present, even for relatively oxidizing buffers such as the QFM buffer, are H2O and H2; the...
Vesicles, water, and sulfur in Reykjanes Ridge basalts
J.G. Moore, J.-G. Schilling
1973, Contributions to Mineralogy and Petrology (41) 105-118
Dredge hauls of fresh submarine basalt collected from the axis of the Reykjanes Ridge (Mid-Atlantic Ridge) south of Iceland were taken aboard R/ V TRIDENT in 1967 and 1971. The samples show systematic changes as the water depth of collection (and eruption) decreases: radially elongate vesicles and concentric zones of vesicles appear...
Role of reef fauna in sediment transport and distribution - Studies from Tektite I and II
H.E. Clifton
1973, Helgoländer Wissenschaftliche Meeresuntersuchungen (24) 91-101
1. Reef organisms may play a major role in the transport and distribution of sediment on the sea floor adjacent to coral reefs. 2. Some fish such as Malacanthus plumieri (Bloch) selectively transport and collect certain types of sediment (such as larger coral and shell fragments). 3. The random movement...
