Search for blood protozoans in the American woodcock
W.B. Krohn, J.R. Hynson
1975, Journal of Wildlife Diseases (11) 107-108
Smears were prepared from heart blood of 55 woodcock collected in central Maine between spring and fall, 1972 and 1973. Peripheral blood taken from the wings of 41 of these birds also was examined. Examination of stained films revealed no infected blood cells. Samples of heart blood from 35 of...

History of fish toxicants in the United States
K.B. Cumming
1975, Special Publication 4
Many bodies of water have been overrun with fish species that are undesirable for the well-being of endemic aquatic biota and are of little or no interest to anglers. This situation has resulted from the transplanting of fish, creation of new waters, increasing fishing pressure and changing water quality. Although...
Utilization of Skylab (EREP) system for appraising changes in continental migratory bird habitat
E.A. Work Jr., D.S. Gilmer
1975, Technical Report CR-147542
The author has identified the following significant results. Surface water statistics using data obtained by supporting aircraft were generated. Signature extraction and refinement preliminary to wetland and associated upland vegetation recognition were accomplished, using a selected portion of the aircraft data. Final classification mapping and...

Sandrewia, n. gen., a problematical plant from the Lower Permian of Texas and Kansas
S.H. Mamay
1975, Review of Palaeobotany and Palynology (20) 75-83
Sandrewia, n. gen., monotypified by S. texana, n. sp., is a plant from Lower Permian beds of north-central Texas and east-central Kansas. It is characterized by stout axes with spirally disposed, laxly inserted, petiolate leaves; the laminae are broadly flabelliform with coarse, open venation....
Vertical crustal movements preceding and accompanying the San Fernando earthquake of February 9, 1971: A summary
Robert O. Castle, Jack P. Church, Michael R. Elliot, Nancy L. Morrison
1975, Tectonophysics (29) 127-140
Comparative elevations referred chiefly to a tidal bench mark with a history of relatively positive movement show that much of the Transverse Ranges of southern California sustained major changes in elevation both before and in association with the ML 6.4 San Fernando earthquake of February 9, 1971. Preseismic changes in...
Trace element evaluation of a suite of rocks from Reunion Island, Indian Ocean
R. A. Zielinski
1975, Geochimica et Cosmochimica Acta (39) 713-734
Reunion Island consists of an olivine-basalt shield capped by a series of flows and intrusives ranging from hawaiite through trachyte. Eleven rocks representing the total compositional sequence have been analyzed for U, Th and REE. Eight of the rocks (group 1) have positive-slope, parallel, chondrite-normalized REE fractionation patterns. Using a...
Age of amphibolites associated with alpine peridotites in the Dinaride ophiolite zone, Yugoslavia
M. A. Lanphere, R. G. Coleman, S. Karamata, J. Pamic
1975, Earth and Planetary Science Letters (26) 271-276
Amphibolites associated with alpine peridotites in the Central Ophiolite zone in Yugoslavia have K-Ar ages of 160–170 m.y. These amphibolites and associated peridotites underwent deep-seated metamorphism prior to tectonic emplacement into the sedimentary-volcanic assemblage of the Dinarides. The alpine peridotites and associated...
Location of the non-tidal current null zone in northern San Francisco Bay
David H. Peterson, T. J. Conomos, W. W. Broenkow, Patrick C. Doherty
1975, Estuarine and Coastal Marine Science (3) 1-11
Variations in Sacramento-San Joaquin River discharge into northern San Francisco Bay causes shifts in location of the bottom density current null zone. At a river flow of 2000 m3/s this null zone is approximately 20 km from the seaward end of the estuary,...
Uranium determination in natural water by the fissiontrack technique
G.M. Reimer
1975, Journal of Geochemical Exploration (4) 425-431
The fission track technique, utilizing the neutron-induced fission of uranium-235, provides a versatile analytical method for the routine analysis of uranium in liquid samples of natural water. A detector is immersed in the sample and both are irradiated. The fission track density observed...
Short chain aliphatic acid anions in oil field waters and their contribution to the measured alkalinity
L.M. Willey, Y.K. Kharaka, T. S. Presser, J. B. Rapp, I. Barnes
1975, Geochimica et Cosmochimica Acta (39) 1707-1711
High alkalinity values found in some formation waters from Kettleman North Dome oil field are due chiefly to acetate and propionate ions, with some contribution from higher molecular weight organic acid ions. Some of these waters contain no detectable bicarbonate alkalinity. For waters...

Interstitial solutions and diagenesis in deeply buried marine sediments: Results from the Deep Sea Drilling Project
F.L. Sayles, F.T. Manheim
1975, Geochimica et Cosmochimica Acta (39) 103-127
Through the Deep Sea Drilling Project samples of interstitial solutions of deeply buried marine sediments throughout the World Ocean have been obtained and analyzed. The studies have shown that in all but the most slowly deposited sediments pore fluids exhibit changes in composition upon burial. These changes can be grouped...
Rare earths in the Leadville Limestone and its marble derivates
J.C. Jarvis, T.R. Wildeman, N.G. Banks
1975, Chemical Geology (16) 27-37
Samples of unaltered and metamorphosed Leadville Limestone (Mississippian, Colorado) were analyzed by neutron activation for ten rare-earth elements (REE). The total abundance of the REE in the least-altered limestone is 4–12 ppm, and their distribution patterns are believed to be dominated by...
