Determination of phosphate in natural waters by activation analysis of tungstophosphoric acid
Herbert E. Allen, Richard B. Hahn
1969, Environmental Science & Technology (3) 844-848
Activation analysis may be used to determine quantitatively traces of phosphate in natural waters. Methods based on the reaction 31P(n,γ)32P are subject to interference by sulfur and chlorine which give rise to 32P through n,p and n,α reactions. If the ratio of phosphorus to sulfur or chlorine is small, as...

The influence of nitrogen on heterocyst production in blue-green algae
Roann E. Ogawa, John F. Carr
1969, Limnology and Oceanography (14) 342-351
A series of experiments on heterocyst production in Anabaena variabilis provides some strong indirect evidence for the role of heterocysts in nitrogen fixation. Of the algae tested (Anabaena variabilis, A. inaequalis, A. cylindrica, A. flos-aquae, Tolypothrix distorta, Gloeotrichia echinulata, Aphanizomenon flos-aquae, Oscillatoria sp., and Microcystis aeruginosa), only those with heterocysts...
A hematopoietic virus disease of rainbow trout and sockeye salmon
Donald F. Amend, William T. Yasutake, Robert W. Mead
1969, Transactions of the American Fisheries Society (98) 796-804
A previously undescribed virus disease epizootic of hatchery rainbow trout (Salmo gairdneri) in British Columbia, Canada is presented. In the same locality, a similar virus disease was experienced among hatchery sockeye salmon (Oncorhynchus nerka). Typical symptoms included flashing, fecal casts, hemorrhagic areas at the base of fins, and petechial hemorrhages...
Studies of certain sulfonamide drugs for use in juvenile chinook salmon
D.F. Amend, J. L. Fryer, K.S. Pilcher
1969, Progressive Fish-Culturist (31) 202-206
Sulfamethazine, introduced to fishery medicine by Snieszko and Friddle in 1950, has been widely accepted for treatment of systemic bacterial infections of fish. When administered to fish in their diet, this drug is effective against susceptible bacteria but has the disadvantages of being slowly absorbed (Snieszko and Friddle, 1951) and...
Equilibrium coexistence of three amphiboles
P. Robinson, H.W. Jaffe, C. Klein Jr., M. Ross
1969, Contributions to Mineralogy and Petrology (22) 248-258
Electron probe and wet chemical analyses of amphibole pairs from the sillimanite zone of central Massachusetts and adjacent New Hampshire indicated that for a particular metamorphic grade there should be a restricted composition range in which three amphiboles can coexist stably. An unequivocal example of such...
Critical review of some multivariate procedures in the analysis of geochemical data
A.T. Miesch
1969, Journal of the International Association for Mathematical Geology (1) 171-184
Simulation experiments have been conducted to examine the potential usefulness of R-mode and Q-mode factor methods in the analysis and interpretation of geochemical data. The R-mode factor analysis experiment consisted of constructing a factor model, using the model to generate a correlation matrix, and attempting to...
Petrological, magnetic and chemical properties of basalt dredged from an abyssal hill in the North-east pacific
B.P. Luyendyk, C.G. Engel
1969, Nature (223) 1049-1050
OVER the years, samples of basalt from the oceanic crust have been taken mainly from seamounts, fracture zones and ridge and rise crests1–6, and rarely from the vast fields of abyssal hills which cover a large part of the deep-sea floor. The basalt sampled from the...
A Rubidium-Strontium study of the Twilight Gneiss, West Needle Mountains, Colorado
F. Barker, Z. E. Peterman, R.A. Hildreth
1969, Contributions to Mineralogy and Petrology (23) 271-282
The Precambrian trondhjemitic Twilight Gneiss (Twilight Granite of CROSS and HOWE, 1905b) of the West Needle Mountains, southwestern Colorado, and its interlayered amphibolite and metarhyodacite yield a Rb-Sr isochron of 1,805±35 m.y. A low initial Sr87/Sr86 ratio of 0.7015 implies that metamorphism of these rocks to amphibolite facies...
Primitive and contaminated basalts from the Southern Rocky Mountains, U.S.A
B. R. Doe, P. W. Lipman, C. E. Hedge, H. Kurasawa
1969, Contributions to Mineralogy and Petrology (21) 142-156
Basalts in the Southern Rocky Mountains province have been analyzed to determine if any of them are primitive. Alkali plagioclase xenocrysts armored with calcic plagioclase seem to be the best petrographic indicator of contamination. The next best indicator of contamination is quartz xenocrysts armored with clinopyroxene. On the rocks and...
History of the geomagnetic field
Richard R. Doell
1969, Journal of Applied Physics (40) 945-954
Direct measurements of the direction and strength of the earth's magnetic field have provided a knowledge of the field's form and behavior during the last few hundreds of years. For older times, however, it has been necessary to measure the magnetism of certain rocks to learn what the geomagnetic field was like. For example, when a...

Dieldrin and DDT: effects on sparrow hawk eggshells and reproduction
Richard D. Porter, Stanley N. Wiemeyer
1969, Science (165) 199-200
Patterns of reproductive failure in declining populations of several European and North American raptorial species were duplicated experimentally with captive American sparrow hawks Falco sparverius that were given a diet containing two commonly used organochlorine insecticides. Major effects on reproduction were increased egg disappearance, increased egg destruction by parent...
Pre-nesting and nesting behavior of the Swainson's warbler
B. Meanley
1969, The Wilson Bulletin (81) 246-257
The Swainson?s Warbler is one of the least known of southern birds. Although fairly common in some parts of its summer range, observations of its breeding biology have been made by very few persons. The present study was conducted mostly at Macon, Georgia; Pendleton Ferry, Arkansas; and Dismal Swamp, Virginia....In...

Nationwide residues of organochlorine pesticides in wings of mallards and black ducks
Robert G. Heath
1969, Pesticides Monitoring Journal (3) 115-123
Nationwide monitoring of organochlorine pesticides in wings of more than 24,000 mallards and black ducks bagged during the1965 and 1966 hunting seasons showed DDE to be the predominant residue, followed in order by DDT, DDD, dieldrin, and heptachlor epoxide. Residues were generally highest in wings from the Atlantic and...
