Geomagnetic paleointensities from radiocarbon‐dated lava flows on Hawaii and the question of the Pacific nondipole low
Robert S. Coe, Sherman Gromme, Edward A. Mankinen
1978, Journal of Geophysical Research B: Solid Earth (83) 1740-1756
Radiocarbon ages have been published for nine basaltic lava flows on the island of Hawaii; the ages range from 2600 to somewhat older than 17,900 years B.P. By using the Thelliers' method in vacuum, geomagnetic paleointensity values were obtained from eight of the lavas; the ninth proved unsuitable. The paleointensities...
Fecundity of the bloater (Coregonus hoyi) in Lake Michigan
Lee Emery, Edward H. Brown Jr.
1978, Transactions of the American Fisheries Society (107) 785-789
Using ovaries sampled seasonally from Lake Michigan bloaters in 1968-1969, we determined that one complement or modal group of eggs is produced each year and spawned mainly during January, February, and March. Fecundities estimated for 65 fish taken in October ranged from 3,230 eggs in one medium-size bloater (241 mm...
Preliminary analytical results for a new U.S. Geological Survey Devonian Ohio Shale Standard SDO-1
Joel S. Leventhal, J.G. Crock, W. Mountjoy, J.A. Thomas, V.E. Shale, Paul H. Briggs, J.S. Wahlberg, M.J. Malcolm
1978, Open-File Report 78-447
Using several analytical techniques, results of analysis of U. S. Geological Survey new standard SDO-1 are given for selected elements. The Devonian black shale shows an organic carbon content of approximately 10.3 percent, a sulfur content of approximately 5.6 percent, and a uranium content of approximately 56 ppm. Some elements...
Low-flow characteristics of streams in the Rock-Fox River basin, Wisconsin
B. K. Holmstrom
1978, Water-Resources Investigations Report 78-85
Low-flow characteristics of streams in the Rock-Fox River basin, Wis., include estimates of low-flow frequency ad flow duration at 13 gaging stations; low-flow frequency characteristics at 32 low-flow partial-record stations and 78 miscellaneous sites; and a list of base-flow discharge measurements at 244 miscellaneous sites. Equations are provided to estimate...
Heritability of tolerance for infectious hematopoietic necrosis in sockeye salmon (Oncorhynchus nerka)
John D. McIntyre, Donald F. Amend
1978, Transactions of the American Fisheries Society (107) 305-308
A hierarchical breeding design was used to demonstrate the heritability of tolerance for infectious hematopoietic necrosis (IHN) in sockeye salmon. Oncorhynchus nerka. Heritability was about 30%, indicating that artificial selection may increase the number of fish that can tolerate the disease....
An automated procedure for the simultaneous determination of specific conductance and pH in natural water samples
D. E. Eradmann, Howard E. Taylor
1978, Analytica Chimica Acta (99) 269-274
An automated, continuous-flow system is utilized to determine specific conductance and pH simultaneously in natural waters. A direct electrometric procedure is used to determine values in the range pH 4–9. The specific conductance measurements are made with an electronically modified, commercially available conductivity meter interfaced to a separate module containing...
Preservation of cycad and Ginkgo pollen
N. O. Frederiksen
1978, Review of Palaeobotany and Palynology (25) 163-179
Pollen grains of Ginkgo, Cycas, and Encephalartos were chemically treated together with pollen of Quercus, Alnus, and Pinus, the latter three genera being used as standards. The experiments showed that: (1) boiling the pollen for 8-10 hours in 10% KOH had little if any effect on any of the grains;...
Biology of larval and metamorphosing sea lampreys, Petromyzon marinus, of the 1960 year class in the Big Garlic River, Michigan, Part II, 1966-72
Patrick J. Manion, Bernard R. Smith
1978, Technical Report 30
The 1960 year class of sea lampreys, Petromyzon marinus, isolated in a tributary of southern Lake Superior continued to yield information on the early life history of the sea lamprey. The larval population persisted and newly metamorphosed individuals were captured from 1966 until the study was terminated in 1972. The...
