Application of remote sensing techniques for appraising changes in wildlife habitat
Harvey K. Nelson, Albert T. Klett, John E. Johnston
1971, Conference Paper, International Workshop in Earth Resources Survey Systems
An attempt was made to investigate the potential of airborne, multispectral, line scanner data acquisition and computer-implemented automatic recognition techniques for providing useful information about waterfowl breeding habitat in North Dakota. The spectral characteristics of the components of a landscape containing waterfowl habitat can be detected with airborne scanners. By...

Biology of larval sea lampreys (Petromyzon marinus) of the 1960 year class, isolated in the Big Garlic River, Michigan, 1960-65
Patrick J. Manion, Alberton L. McLain
1971, Technical Report 16
The early life history of the sea lamprey, from hatching to the first capture of metamorphosed individuals, is described from observations on a known-age population isolated in a tributary of southern Lake Superior. The population had its origin in the spring of 1960, when 722 sea lampreys nearing spawning condition...

Periodic water- and air-temperature records for Utah streams, 1966-70
G.L. Whitaker
1971, Utah Basic-Data Release 22
Since 1967, all Geological Survey hydrographers have been instructed to observe and record the water and air temperatures at times when water-discharge measurements were being made at stream-gaging stations in Utah. The frequency of these observations generally varies from I to 5 weeks, depending upon the magnitude of the stream...
Results from the apollo-12 passive seismic experiment
G. Latham
1971, Earthquake Information Bulletin (USGS) (3) 4-9
The objective of the passive seismic experiment is to measure vibrations of the lunar surface produced by all natural and artificial sources of seismic energy and to use these data to deduce the internal structure and composition of the moon, the nature of forces which may cause deformation of the...
An annotated bibliography of fauna and flora described from the Dockum Group of Triassic age in eastern New Mexico and West Texas
James C. Wright, Warren I. Finch
1971, Open-File Report 71-333
This annotated bibliography was prepared by Warren I. Finch from a rough copy compiled by the late James C. Wright in either late 1967 or early 1968 as an aid to his understanding of the stratigraphic distribution of uranium deposits in Triassic rocks of the Southern high Plains. He did...
Water Resources Data for New Mexico; Part 1, Surface Water Records
Water Resources Division, U.S. Geological Survey
1971, Water Data Report NM-70-1
Surface-water records for the 1970 water year for New Mexico, including records of streamflow or reservoir storage at gaging stations, partial-record stations, and miscellaneous sites, are given in this report and their locations shown in figures 1, 2. Records for a few pertinent gaging stations in bordering States also are...
Isotopic composition of strontium in three basalt-andesite centers along the Lesser Antilles arc
C. E. Hedge, J.F. Lewis
1971, Contributions to Mineralogy and Petrology (32) 39-47
Si87/Sr86 ratios have been determined for lavas and py lastic rocks from three basalt-andesite centers along the Lesser Antilles arc—Mt. Misery on the island of St. Kitts, Soufriere on the island of St. Vincent, and Carriacou, an island of The Grenadines. The average Si87/Sr86 content of these rocks...
Spectral reflectance and photometric properties of selected rocks
Robert D. Watson
1971, Remote Sensing of Environment (2) 95-100
Studies of the spectral reflectance and photometric properties of selected rocks at the USGS Mill Creek, Oklahoma, remote sensing test site demonstrate that discrimination of rock types is possible through reflection measurements, but that the discrimination is complicated by surface conditions, such as weathering and lichen growth. Comparisons between fresh-broken,...
40Ar/39Ar technique of KAr dating: A comparison with the conventional technique
G. Brent Dalrymple, M. A. Lanphere
1971, Earth and Planetary Science Letters (12) 300-308
K-Ar ages have been determined by the40Ar/39Ar total fusion technique on 19 terrestrial samples whose conventional K-Ar ages range from 3.4 my to nearly 1700 my. Sample materials included biotite, muscovite, sanidine, adularia, plagioclase, hornblende, actinolite, alunite, dacite, and basalt. For 18...
Limited-interval definitions of the photometric functions of lunar crater walls by photography from orbiting Apollo
R.L. Wildey
1971, Icarus (15) 93-99
By the use of only relative photometry (intraframe) it is shown that the photometric functions of material reposed on the inner walls of some of the ypunger lunar craters photographed on the far side of the Moon from the Apollo 11 Command Module...
Scanning electron microscopy of clays and clay minerals
B.F. Bohor, R.E. Hughes
1971, Clays and Clay Minerals (19) 49-54
The scanning electron microscope (SEM) proves to be ideally suited for studying the configuration, texture, and fabric of clay samples. Growth mechanics of crystalline units—interpenetration and interlocking of crystallites, crystal habits, twinning, helical growth, and topotaxis—also are uniquely revealed by the SEM.Authigenic kaolins make up the bulk of the examples...
Variation of iridium in a differentiated tholeiitic dolerite
L. P. Greenland
1971, Geochimica et Cosmochimica Acta (35) 319-322
Iridium has been determined in a drill core from the Great Lake (Tasmania) dolerite sheet. Iridium decreases systematically from the mafic dolerites (0.25 ppb) to the granophyres (0.006 ppb). The trend with differentiation closely parallels that of chromium....
Imaging of Mercury and Venus from a flyby
B. C. Murray, M. J. S. Belton, G. Edward Danielson, M. E. Davies, G. P. Kuiper, B. T. O’Leary, V.E. Suomi, N.J. Trask
1971, Icarus (15) 153-173
This paper describes the results of study of an imaging experiment planned for the 1973 Mariner Venus/Mercury flyby mission. Scientific objectives, mission constraints, analysis of alternative systems, and the rationale for final choice are presented. Severe financial constraints ruled out the best technical alternative for flyby imaging, a film/readout system,...
Geomagnetic polarity epochs: age and duration of the olduvai normal polarity event
C. S. Grommé, R. L. Hay
1971, Earth and Planetary Science Letters (10) 179-185
New data show that the Olduvai normal geomagnetic polarity event is represented in Olduvai Gorge, Tanzania, by rocks covering a time span of roughly from 0.1 to 0.2 my and is no older than 2.0 my. Hence the long normal polarity event...
Kaersutite - A product of reaction between pargasite and basanite at Dish Hill, California
H. G. Wilshire, L. C. Calk, E.C. Schwarzman
1971, Earth and Planetary Science Letters (10) 281-284
Paragasitic amphibole, occurring interstitially and as veins in peridotite inclusions in basanite, has reacted with the host basanite to form kaersutitic amphibole. The amphibole compositions vary with respect to distance from the edge of the xenolith; iron, titanium, and potassium contents are...
Geological provinces of the near side of the moon
J.F. McCauley, D.E. Wilhelms
1971, Icarus (15) 363-367
Systematic geologic mapping of the near side of the Moon has provided the basis for defining and delineating the major geological provinces of the near side. From the nature of the provinces and their distribution patterns a general historical sequence evolves. Five main...
On the origin of lunar soil 12033
P.A. Beadecker, F. Cuttitta, H. J. Rose Jr., R. Schaudy, J. T. Wasson
1971, Earth and Planetary Science Letters (10) 361-364
The lunar soil 12033 is compositionally distinctly different from both the local rocks at the Apollo 12 site and other lunar samples. It must be a recent deposit, else it would not have retained its identity. It contains a meteoritic component which...

A basket for washing benthological samples
James H. Selgeby
1971, Transactions of the American Fisheries Society (100) 590-591
Since benthological samples collected with dredges are usually too large to be preserved in toto, a washing method must be employed to reduce the sample volume without losing or damaging the organisms. Traditionally, the sample is washed in a sieve until the volume is small enough for convenient handling...
