The tullibee
Stanford H. Smith
1966, Minnesota Conservation Volunteer (29) 49-50
Early explorers and settlers of the northeastern United States and southern Canada found lakes teeming with fish that had white flesh and were good to eat. The larger of these they called whitefish, differentiating two kinds- the lake whitefish and the round or menominee whitefish. These looked much...
Shattuckite and plancheite: A crystal chemical study
Howard T. Evans Jr., Mary E. Mrose
1966, Science (154) 506-507
The orthorhombic crystal structures of shattuckite, Cu5( SiO3)4(OH)2 and planchétite, Cu8(Si4011)2(OH)4 H2O, have been solved. Shattuckite contains silicate chains similar to pyroxene in a complex association with copper atoms, while the closely related planchéite contains silicate chains similar to amphibole....
Observed variations in the strontium concentration of sea water
E.E. Angino, G.K. Billings, N. Andersen
1966, Chemical Geology (1) 145-153
On samples obtained from five widely separated areas of the North Atlantic Ocean 91 determinations of strontium were made. These include surface and deep-water samples from both the cold North Atlantic area and the warm subtropical Caribbean area. The results differ from...
Variational method of determining effective moduli of polycrystals with tetragonal symmetry
R. Meister, L. Peselnick
1966, Journal of Applied Physics (37) 4121-4125
Variational principles have been applied to aggregates of randomly oriented pure‐phase polycrystals having tetragonal symmetry. The bounds of the effective elastic moduli obtained in this way show a substantial improvement over the bounds obtained by means of the Voigt and Reuss assumptions. The Hill average is found to be a good approximation in...
Disequilibrium of the 238U series in basalt
B.L.K. Somayajulu, M. Tatsumoto, J.N. Rosholt, R. J. Knight
1966, Earth and Planetary Science Letters (1) 387-391
Radioisotope analyses of basalt samples from Hawaii, Japan, and Iwo Jima show that: (1)234U and238U are virtually in radioactive equilibrium, (2)230Th exceeds equilibrium values in all these samples, (3)210Pb concentrations range from 10–200% of the equilibrium values and average 30% deficient, and...
Sediment movement on the continental shelf near Washington and Oregon
M. Grant Gross, Jack L. Nelson
1966, Science (154) 879-885
The nuclides zinc-65 and cobalt-60 associated with river-borne particulate matter are incorporated in sediment on the Continental Shelf near the Colum- ia River. Changes in the relative concentrations of zinc-65 and cobalt-60 and in the ratio of the activity of zinc-65 and cobalt-60 suggest that radioactive sediment moves northward 12...
Color variations within glacial till, east-central North Dakota--A preliminary investigation
T. E. Kelly, Claud H. Baker Jr.
1966, Journal of Sedimentary Petrology (36) 75-80
Color variations (orange zones within buff-colored till) in drift in east-central North Dakota are believed to represent two tills of separate origin. Mean size, standard deviation, and number and type of pebbles show greater difference between the two tills than do skewness, kurtosis, and partial chemical analyses. Probably blocks of...
Determination of Columbia River flow times from Pasco, Washington using radioactive tracers introduced by the Hanford reactors
Jack L. Nelson, R.W. Perkins, W.L. Haushild
1966, Water Resources Research (2) 31-39
Radioactive tracers introduced into the Columbia River in cooling water from the Hanford reactors were used to measure flow times downstream from Pasco, Washington, as far as Astoria, Oregon. The use of two tracer methods was investigated. One method used the decay of a steady release of Na24 (15-hour half-life)...

Food of young-of-the-year walleyes in Lake Erie
David R. Wolfert
1966, Fishery Bulletin (65) 489-494
Stomach contents were examined for 794 young-of-the-year (0-group) walleyes (Stizostedion vitreum vitreum) captured by trawls at 17 locations in western Lake Erie in June-November 1962. Food organisms were found in 92.5 percent of the stomachs. Food varied with geographic location and season of capture, but within areas and seasons, selection...
