Not all publications have extents, not all extents are completely accurate
Geology

Leveling
1966, Topographic instructions of the United States geological survey 2E1-2E5
Geodetic leveling by the U.S. Geological Survey provides a framework of accurate elevations for topographic mapping. Elevations are referred to the Sea Level Datum of 1929....
Rare earths in phosphorites: Geochemistry and potential recovery
Z. S. Altschuler, Sol Berman, Frank Cuttitta
1966, Open-File Report 66-3
Rare earths are but trace constituents of marine apatite. However, as millions of tones of such apatite are dissolved annually to make phosphoric acid, an opportunity exists for greatly increasing RE output as by-product of fertilizer production. New, complete, quantitative analysis of RE in representative apatite concentrates reveal that the...
Some blood chemistry values for five Chesapeake Bay area fishes
J. B. Hunn, P.F. Robinson
1966, Chesapeake Science (7) 173-175
Blood samples from gizzard shad,largemouth bass, white perch, pumpkinseed, and toadfish were analyzed for hemoglobin, total plasma protein, total plasma cholesterol, and ion concentrations of plasma sodium, potassium, and chloride. The hemoglobin concentration and total plasma cholesterol found in a given species seem to have positive correlation with the customary activity level...
Some alkali and titania analyses of tektites before and after G-1 precision monitoring
D.B. Tatlock
1966, Geochimica et Cosmochimica Acta (30) 123-128
A comparison of 55 older analyses of Australasian tektites with 110 modern precisely monitored analyses suggests that more than half of the older alkali and titania determinations are decidedly inaccurate and misleading. Deviations of the older analyses from the restricted values of the...
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...
Preparation of dart tags for use in the field
Joseph R. Higham
1966, Progressive Fish-Culturist (28) 205
Tagging in the field requires an efficient method of preparing the tags for dispensation under a wide range of conditions. The method described here was very efficient in an extensive tagging program on Oahe Reservoir, South Dakota....
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...
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...
