Nickel in high-alumina basalts
C. E. Hedge
1971, Geochimica et Cosmochimica Acta (35) 522-524
New analyses of high-alumina basalts reveal an average nickel content higher than previously indicated. Ni in high-alumina basalts correlates with magnesium in the same way as it does in other basalt types. There is therefore no reason, based on Ni contents, to hypothesize...
Giant American brook lampreys, Lampetra lamottei, in the upper Great Lakes
Patrick J. Manion, Harold A. Purvis
1971, Journal of the Fisheries Research Board of Canada (28) 616-620
Five female American brook lampreys, Lampetra lamottei, collected in lakes Michigan and Huron averaged nearly twice as long and about six times as heavy as American brook lampreys of normal size. Three factors suggested that the giant lampreys may have fed parasitically after metamorphosis: morphological adaptations of the species for parasitic...

Selenography and selenodesy with Apollo whole-disk lunar photographs I. Selenography
D.W.G. Arthur
1971, Icarus (14) 388-418
The Apollo whole-disk lunar photographs, with spacecraft lunar nadirs about 70° from the center of mean face, have considerable selenodetic potential provided that the requirements of resolution and precision can be met. Uncertainties in the internal camera geometry degrade the precision and make...

Selective food preferences of walleyes of the 1959 year class in Lake Erie
John W. Parsons
1971, Transactions of the American Fisheries Society (100) 474-485
Stomachs were examined from 1,473 walleyes (Stizostedion vitreum vitreum) of the 1959 year class collected in western Lake Erie from June 1959 to October 1960. In the same period, the relative abundance and lengths of potential forage species were determined from trawl catches. The walleye fed almost entirely on fish....
Seasonal distribution of zooplankton in the northern basin of Lake Chad
A.H. Robinson, Patricia K. Robinson
1971, Journal of Zoology (163) 25-61
More than 300 pairs of fine and coarse mesh plankton net samples were collected in the northern basin of Lake Chad during an 18-month period, June 1967 to November 1968. The seasonal distribution and abundance of the dominant species of Rotifera and Crustacea are given in addition to a general...

Effects of temperature on electrolyte balance and osmoregulation of the alewife (Alosa pseudoharengus) in fresh and sea water
Jon G. Stanley, Peter J. Colby
1971, Transactions of the American Fisheries Society (100) 624-638
A study of the effects of temperature and salinity on ionoregulation in the alewife, Alosa pseudoharengus, revealed that concentrations of sodium, potassium, and calcium in plasma and muscle were similar in fish adapted to fresh water and those adapted to sea water. The non-stressed alewife is apparently an excellent...

Comparison of Sr87 Sr86 for sea-water strontium and the Eimer and Amend SrCO3
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....
Glacial marine sediments in the precambrian Gowganda formation at Whitefish Falls, Ontario (Canada)
D. A. Lindsey
1971, Palaeogeography, Palaeoclimatology, Palaeoecology (9) 7-25
Study of a well-exposed section of the Gowganda Formation at Whitefish Falls, Ontario, suggests criteria for the recognition of glacial marine sediments. Thickness of hundreds of feet, lateral continuity, faint internal stratification, sorted lenses of sandstone and conglomerate, and dropstones characterize much of the tillite. Thickness of hundreds of feet,...
The earth's core: Speculations on its chemical equilibrium with the mantle
R. Brett
1971, Geochimica et Cosmochimica Acta (35) 203-221
A review of the literature indicates that a reasonable estimate of the composition of the earth's core is iron with Ni0–5, Si10–25 (wt.%). Thermodynamic calculations and comparison of chondritic with terrestrial abundances indicate that 1 wt.% each of Mn, P, and Cr might also be present. A core of this composition...
Uranium-series dating of some pleistocene marine deposits in Southern California
Barney J. Szabo, J. G. Vedder
1971, Earth and Planetary Science Letters (11) 283-290
Analyses of uranium isotopes and their long-lived daughter products showed evidence of uranium migration in most of the 22 fossil mollusk shell samples from marine terrace deposits in southern California. Two samples, however, remained an ideal closed system as indicated by concordant230Th/234U...

A large tektite from Cuba is classified with other North American tektites on the basis of its age. The major-element chemistry, oxygen isotopic composition, refractive index and density of the Cuban tektite are within the ranges exhibited by bediasites....
Hydrogeochemical effects of injecting wastes into a limestone aquifer near Pensacola, Florida
Donald A. Goolsby
1971, Groundwater (9) 13-19
Acidic industrial wastes have been injected into deep wells in a limestone aquifer near Pensacola, Florida, since 1963. Prior geohydrologic studies in the area had indicated that the limestone aquifer contained nonpotable water and was overlain by an extensive clay confining layer.Two injection wells are presently being used to inject...
The stress of Formalin treatments in rainbow trout (Salmo gairdneri) and coho salmon (Oncorhynchus kisutch)
Gary Wedemeyer
1971, Journal of the Fisheries Research Board of Canada (28) 1899-1904
Changes in gill function, acid–base balance and pituitary activation occurring during standard 200 ppm formalin treatments of juvenile rainbow trout (Salmo gairdneri) and coho salmon (Oncorhynchus kisutch) were compared. Plasma Cl−, Ca++, total CO2, and interrenal vitamin C in the trout declined continuously and in proportion to the exposure time, but...
Interaction between duck hepatitis virus and DDT in ducks
W.L. Ragland, Milton Friend, D.O. Trainer, N.E. Sladek
1971, Research Communications in Chemical Pathology and Pharmacology (2) 236-244
Injections of duck hepatitis virus (DVH) decreased, and exposure to DDT increased, hepatic microsomal mixed-function oxidase activity. Injection of DFV prior to exposure to DDT did not prevent stimulation of hepatic microsomal mixed-function oxidase activity by DDT and may have enhanced it....
Some blood chemistry values for the juvenile coho salmon (Oncorhynchus kisutch)
Gary Wedemeyer, K. Chatterton
1971, Journal of the Fisheries Research Board of Canada 606-608
Overlapping Gaussian distribution curves were resolved into normal ranges for 1800 clinical test values obtained from caudal arterial blood or plasma of more than 1000 juvenile coho salmon (Oncorhynchus kisutch) held under defined conditions of diet and temperature. Estimated normal blood chemistry ranges were bicarbonate, 9.5–12.6 mEq/liter; blood urea nitrogen (BUN),...
