M. A. Haegele, Rick H. Hudson
1974, Archives of Environmental Contamination and Toxicology (2) 356-363
A group of 16 mallard hens (Anas platyrhynchos), that had been given feed containing 40 ppm ofp,p'-DDE for 96 days, laid eggs with shells averaging about 15%–20% thinner than those of ten control birds during and up to 42 days after treatment. In eight of the treated birds killed at...
Offset plutons and history of movement along the McKinley segment of the Denali Fault system, Alaska
Bruce L. Reed, Marvin A. Lanphere
1974, GSA Bulletin (85) 1883-1892
The Foraker and McGonagall plutons, bodies of granodiorite with nearly identical mineralogy and chemistry, are considered to be parts of a single igneous mass that has undergone right-lateral displacement of about 38 km along the McKinley segment of the Denali fault system since the igneous mass crystallized about 38 m.y....

Leachate plumes in a highly permeable aquifer
Grant E. Kimmel, Olin C. Braids
1974, Groundwater (12) 388-392
Two landfills, 27 and 41 years old, were studied and found to have plumes of leachate-contaminated ground water extending 10,600 and 5,000 ft (3,200 and 1,500 m), respectively, from the site of deposition in the upper glacial aquifer on Long Island, New York. The plumes sink to the bottom of...
Spectrofluorimetric procedure using 2,3-napthalenediamine for determining selenium in rocks
Marian M. Schnepfe
1974, Journal of Research of the U.S. Geological Survey (2) 631-636
A spectrofluorimetric procedure using 2,3-naphthalenediamine is given for determining submicrogram and microgram quantities of selenium in mineralized rocks. Conditions for the satisfactory isolation and concentration of the selenium are investigated and tested on six USGS standard rocks of various types. Selenium contents of samples treated by an alkaline sinter and...
Molluscan phylogeny: The paleontological viewpoint
B. Runnegar, J. Pojeta Jr.
1974, Science (186) 311-317
Stasek theorized that the extant mollusks are the progeny of three separate lineages that separated before the phylum was well established. He wrote that no known intermediate forms, fossil or living, bridge the "enormous gaps between any two of the three lineages," and therefore treated each as a separate subphylum....
Development of the Circum-Antarctic Current

1974, Science (186) 144-147
Deep-sea drilling in the Southern Ocean south of Australia and New Zealand shows that the Circum-Antarctic Current developed about 30 million years ago in the middle to late Oligocene when final separation occurred between Antarctica and the continental South Tasman Rise. Australia had commenced drifting northward from Antarctica 20 million...

Radioactive waste storage in the arid zone
Isaac J. Winograd
1974, Eos Science News (55) 884-894
By the turn of the century, nuclear power may generate more than one-half of the electric energy, and about one-third of the total energy consumed in the United States [Thompson, 1971; Chapman et al., 1972]. By 2020, the total quantity of high-level radioactive wastes (HLW) generated as a byproduct of nuclear...
Trichomoniasis in the Hawaiian barred dove
R. M. Kocan, W. Banko
1974, Journal of Wildlife Diseases (10) 359-360
Two barred doves found in the south Kona district of the island of Hawaii were diagnosed as having trichomoniasis on the basis of gross and microscopic lesions. This brings the confirmed list of columbid species susceptible to natural trichomoniasis to four and is the first report of the disease...

Sea otters: Their role in structuring nearshore communities
J. A. Estes, J. F. Palmisano
1974, Science (185) 1058-1060
A comparison of western Aleutian Islands with and without sea otter populations shows that this species is important in determining littoral and sublittoral community structure. Sea otters control herbivorous invertebrate populations. Removal of sea otters causes increased herbivory and ultimately results in the destruction of macrophyte associations. The observations suggest...
The 1973 distribution and abundance of breeding ospreys in the Chesapeake Bay
Charles J. Henny, Morton M. Smith, Vernon D. Stotts
1974, Chesapeake Science (15) 125-133
An aerial survey in association with several intensive ground surveys yielded the first estimate of the size of the osprey (Pandion haliaetus carolinensis) nesting population in Chesapeake Bay. The 1973 population was estimated at 1,450 ± 30 pairs, of which 713 were on the western shore and 737 on the...
Chert derived from magadiite in a lacustrine deposit near Rome, Malheur County, Oregon

Nodules and thin beds of chert occur in the upper part of the informally named Rome beds, about 8 11 km southwest of Rome, Oreg. The chert is in green to gray mudstone, about 8 m beneath a conspicuous gray and yellow zeolitic tuff. The bedded chert contains molds of...

The youngest strata recognized in the Madison Limestone arc dated by foraminifers and corals at two localities on the west flank of the Bighorn Mountains in Wyoming and Montana. Fossils collected in situ from the Madison at Shell Canyon represent Zone 12 of Mamet and Skipp of late Salem age...
Correlation of uppermost Precambrian and lower Cambrian strata from southern to east-central Nevada
John H. Stewart
1974, Journal of Research of the U.S. Geological Survey (2) 609-618
Study of exposed uppermost Precambrian and Lower Cambrian strata in southern and east-central Nevada and intervening areas indicates that the Johnnie Formation of southern Nevada and the McCoy Creek Group (restricted) are correlative. In detail, the uppermost units of both sequences, the Rainstorm Member of the Johnnie Formation and the...

E. B. Ekren, W. D. Quinlivan, R.P. Snyder, F. J. Kleinhampl
1974, Journal of Research of the U.S. Geological Survey (2) 599-608
The Lunar Lake caldera is in northern Nye County, Nev., about 70 mi (110 km) east-northeast of Tonopah. It is the youngest caldera in the central Nevada multiple-caldron complex and the source of the tuff of Lunar Cuesta, a multiple-flow simple cooling unit of quarts latitic welded tuff that is...
Phosphorus, iron, and manganese distribution in sediment cores of six Wisconsin lakes
Gilbert C. Bortleson, G. Fred Lee
1974, Limnology and Oceanography (19) 794-801
Depositional patterns of iron, manganese, and phosphorus in one central and five northern Wisconsin lakes ranging from oligotrophic to eutrophic, primarily from natural causes, have been investigated. One-meter cores from one or more locations within each lake were analyzed. The historical pattern of iron and manganese deposition is closely related...
Correlation between geophysical data and rock types in the Piedmont and coastal plain of northeast Virginia and related areas
Louis Pavlides, K Sylvester, David L. Daniels, Robert G. Bates
1974, Journal of Research of the U.S. Geological Survey (2) 569-580
Physical, chemical, and mineralogic characteristics of rock units in parts of the northeast Virginia Piedmont are reflected in the aeromagnelic, aeroradioactivity, and gravity data for this area. Magnetic anomalies show the areal distribution of rocks containing magnetite. Aeroradiometric anomalies in the Piedmont and Coastal Plain provinces are directly related to...
Dissolved organic carbon (DOC), an index of organic contamination in ground water near Barstow, California

The alluvial aquifer underlying and adjacent to the Mojave River near Barstow, California, has been subjected to degradation from percolation of industrial and municipal wastes for more than 60 years. Effluents discharged to the aquifer have contained high concentrations of both organic (detergents, oil and grease, phenols, humic compounds, and...
