Planktonic diatoms of Lake Ontario
Jerry F. Reinwand
1969, Technical Report 14
The major species of diatoms in surface collections from Lake Ontario in September 1964 were Asterionella formosa, Fragilaria crotonensis, and Tabellaris fenestrata. Dominant species in the deep-water samples were Stephanodiscus astraea, S. astraea var. mintula, and F. crotonensis. The diatom flora in surface collections varied among several stations in the...
Fishery survey of U. S. waters of Lake Ontario
LaRue Wells
1969, Technical Report 14
Gill nets and trawls were fished by the Bureau of Commercial Fisheries R/V Cisco during September 19-23, 1964, at several locations and depths in the offshore United States waters of Lake Ontario. Water temperatures were low (3.7-8.3 A?C) at all fishing stations except one (16.4 A?C). Supplementary data were provided...
Ecological relationships of breeding blue-winged teal to prairie potholes
Roderick C. Drewien, Paul F. Springer
1969, Report Series 6
Ecology of breeding blue-winged teal (Anas discors) was studied on the Waubay Study Area in Day County, South Dakota, in 1965 and 1966. Breeding pair use of the wetland habitat and importance of Type 1 ponds in the wetland complex were evaluated. Changes in breeding pair densities and wetland habitat...

Infectious pancreatic necrosis virus: Lyophilization and subsequent stability in storage at 4 C
Ken Wolf, M.C. Quimby, C.P. Carlson
1969, Applied Microbiology (17) 623-624
Infectious pancreatic necrosis virus (ATCC strain VR # 299) was lyophilized with different additives and stored at 4 C. Ampoules were assayed at 2 days, at 1, 3, and 6 months, and at 1, 3, and 4 years. Processing losses were least and subsequent maintenance of infectivity was best in...
Geochemistry and hydrodynamics of the Paradox Basin region, Utah, Colorado and New Mexico
B.B. Hanshaw, G.A. Hill
1969, Chemical Geology (4) 263-294
The Paradox Basin region is approximately bounded by the south flank of the Uinta Basin to the north, the Uncompahgre uplift and San Juan Mountains to the east, the Four Corners structural platform to the southeast, the north rim of the Black Mesa Basin and the Grand Canyon to...

Blueschist-facies metamorphism related to regional thrust faulting
M. Clark Blake Jr., W. Porter Irwin, R. G. Coleman
1969, Tectonophysics (8) 237-246
Rocks of the blueschist (glaucophane schist) facies occur throughout the world in narrow tectonic belts associated with ultramafic rocks. In the Coast Range province of California, blueschist rocks are devloped in the eugeosynclinal Franciscan Formation of Late Mesozoic age. The blueschist rocks form a narrow belt for more than 800...
Fractionation of gold in a differentiated tholeiitic dolerite
J.J. Rowe Jr.
1969, Chemical Geology (4) 421-427
Gold content was determined, by neutron-activation analysis, in samples from a drill core through the Great Lake sheet, Tasmania, a differentiated tholeiitic dolerite. The gold content of parts of the core seems to be related to the mafic index. The variation of...

The isotopic composition of lead in potassium feldspars from some 1.0-b.y. old North American igneous rocks
Robert Eugene Zartman, G.J. Wasserburg
1969, Geochimica et Cosmochimica Acta (33) 901-942
The isotopic composition of lead and the uranium, thorium and lead concentrations in potassium feldspars are determined for more than 30 1.0-b.y. old North American igneous rocks. Samples representing a broad spectrum in petrographic type and mode of occurrence were chosen; an effort was made to include only rocks having...

On the global variations of terrestrial heat-flow
W.H.K. Lee (compiler)
1969, Physics of the Earth and Planetary Interiors (2) 332-341
Over 3 500 measurements of surface heat-flux have been catalogued and analyzed to study the large-scale variations of terrestrial heat-flow. It was found that heat-flow values are correlated with major geologic provinces: higher averages and scattered values in active tectonic regions, and lower averages and more uniform values in stable...
Florida submergence curve revised: Its relation to coastal sedimentation rates
D.W. Scholl, F.C. Craighead Sr., Minze Stuiver
1969, Science (163) 562-564
New data substantiate as well as modify the south Florida submergence curve, which indicates that eustatic sea level has risen continuously, although at a generally decreasing rate, during the last 6500 to 7000 sidereal years (5500 standard radiocarbon years) to reach its present position. Accumulation rates of coastal deposits are...
Seismic activity and faulting associated with a large underground nuclear explosion
R. M. Hamilton, F. A. McKeown, J. H. Healy
1969, Science (166) 601-604
The 1.1-megaton nuclear test Benham caused movement on previously mapped faults and was followed by a sequence of small earthquakes. These effects were confined to a zone extending not more than 13 kilometers from ground zero; they are apparently related to the release of natural tectonic strain....
Ellsworth mountains: Position in West Antarctica due to sea-floor spreading
J.M. Schopf
1969, Science (164) 63-66
Similarities of middle and upper Paleozoic deposits of the Ellsworth Mountains with those of the Pensacola, Horlick, and other Transantarctic mountains indicate that all these ranges may have had a related geologic history. A tentative explanation is now suggested which involves sea-floor spreading and translocation of the Ellsworth crustal block...

High-pressure mechanical instability in rocks
James D. Byerlee, W.F. Brace
1969, Science (164) 713-715
At a confining pressure of a few kilobars, deformation of many sedimentary rocks, altered mafic rocks, porous volcanic rocks, and sand is ductile, in that instabilities leading to audible elastic shocks are absent. At pressures of 7 to 10 kilobars, however, unstable faulting and stick-slip in certain of these rocks...
Infrared scanning images: An archeological application
G. G. Schaber, G.J. Gumerman
1969, Science (164) 712-713
Aerial infrared scanner images of an area near the Little Colorado River in north-central Arizona disclosed the existence of scattered clusters of parallel linear features in the ashfall area of Sunset Crater. The features are not obvious in conventional aerial photographs, and only one cluster could be recognized on the...
Species diversity: Benthonic Foraminifera in Western North Atlantic
M.A. Buzas, T. G. Gibson
1969, Science (163) 72-75
Maximum species diversity occurs at abyssal depths of greater than 2500 meters. Other diversity peaks occur at depths of 35 to 45 meters and 100 to 200 meters. The peak at 35 to 45 meters is due to species equitability, whereas the other two peaks correspond to an increase in...
