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...
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...
Genetic implications of the shapes of martian and lunar craters
R.J. Pike
1971, Icarus (15) 384-395
Craters on Mars and the Moon are alike in that larger craters differ in shape from smaller ones, and older craters differ in shape from younger ones. Smoothed depth-diameter curves for 41 large martian craters photographed by Mariner IV inflect at a crater...
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 test of the 40Ar/39Ar age spectrum technique on some terrestrial materials
M. A. Lanphere, G. Brent Dalrymple
1971, Earth and Planetary Science Letters (12) 359-372
40Ar/39Ar age spectra were determined for 10 terrestrial rock and mineral samples whose geologic history is known from independent evidence. The spectra for six mineral and whole rock samples, including biotite, feldspar, hornblende, muscovite, and granodiorite, that have experienced post-crystallization heating did...
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...
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...
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,...
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...

Sea lampreys in the Great Lakes of North America
Bernard R. Smith
M.W. Hardisty, I.C. Potter, editor(s)
1971, Book chapter, The biology of lampreys
The movement of sea lampreys into the upper Great Lakes (Superior, Michigan, and Huron) initiated a series of biological changes which have extended beyond the fish directly attacked by the parasite. The threat posed by the sea lamprey was not generally recognized until it was well established in all...

Albinism in lampreys in the upper Great Lakes
Robert A. Braem, Everett L. King

Albinism in fishes is relatively rare except in some stocks of hatchery-reared salmonids. In the Petromyzonidae, only four albino lampreys have been reported....
Alewife dieoffs: Why do they occur?
Peter J. Colby
1971, Limnos (4) 18-27
Periodid midwinter, early spring, and summer mortalities of alewives (Alosa pseudoharengus) have been common in the Great Lakes since the first appearance of the silvery marine invader in Lake Ontario in the mid-1870's. In 1967 a nationally publicized dieoff of tremendous magnitude (estimated at several hundred million pounds of...
Sampling of fish muscle for M.S.222 and quinaldine residues
Charles W. Luhning, Paul D. Harman
1971, Journal of the Fisheries Research Board of Canada (28) 113-115
Large variations in concentrations of M.S. 222 (tricaine methanesulfonate) and quinaldine (2-methylquinoline) residues occurred in various areas of fish fillets. Residue analyses of replicate samples from homogenized fillets yielded more representative results than samples cut from various areas of fillets....

A procedure for testing the antigenicity of vaccines for immunization of fish against Furunculosis
Jamieson E. Holway, G.W. Klontz
1971, Progressive Fish-Culturist 42-44
Furnunculosis, a bacterial disease caused by Aeromonas salmonicida, is potentially one of the most devastating diseases in trout and salmon hatcheries. The disease may be controlled by three methods. The most frequently used method of control has been drug therapy. Unfortunately, the bacteria often develop resistance to the...

R.A. Hildreth, W.T. Henderson
1971, Geochimica et Cosmochimica Acta (35) 235-238
A series of analyses were undertaken to determine a precise difference between sea-water strontium and the Eimer and Amend SrCO3 standard. A mean difference between the sea-water composite and the Eimer and Amend SrCO3 of 0.00107 ± 0.000042 was obtained....
