A list of materials necessary to build and use a 53-m-long cable-chain drag is presented. Techniques are described for searching, finding, and marking nests in a typical area of grassland.During nine nesting seasons, 7,894 nests representing 32 species were found by searching fields with cable-chain drags. Only 2% of the...

Fluorite solubility equilibria in selected geothermal waters
D. Kirk Nordstrom, E. A. Jenne
1977, Geochimica et Cosmochimica Acta (41) 175-188
Calculation of chemical equilibria in 351 hot springs and surface waters from selected geothermal areas in the western United States indicate that the solubility of the mineral fluorite, CaF2, provides an equilibrium control on dissolved fluoride activity. Waters that are undersaturated...
Hydrothermal transport of heavy metals by seawater: The role of seawater/basalt ratio
W. Seyfried, J. L. Bischoff
1977, Earth and Planetary Science Letters (34) 71-77
Seawater reacted with basaltic glass at 260°C and 500 bars under water-dominated conditions (50 : 1 water/rock ratio) efficiently leached and maintained heavy metals in solution. Cu, Zn, and Ba are transferred in significant proportions to the aqueous phase, while Fe...
Recent metalliferous sediment in the North Pacific manganese nodule area
J. L. Bischoff, R.J. Rosenbauer
1977, Earth and Planetary Science Letters (33) 379-388
Quaternary sediments cored in the northeast Pacific nodule area (DOMES site C, 14°N, 126°W) contain a significant amount of hydrothermal metalliferous mud. Water content, color, mineralogy, and chemical composition are analogous to metalliferous sediments of the subequatorial East Pacific Rise.Correction for contribution of pelagic clay indicates the metalliferous fraction to...
Control of whirling disease (Myxosoma cerebralis): Effects of drying, and disinfection with hydrated lime or chlorine
G. L. Hoffman, J. J. O’Grodnick
1977, Journal of Fish Biology (10) 175-179
Thorough air drying of contaminated mud killed the spores of Myxosoma cerebralis. Treatment of simulated earthen ponds with hydrated lime with up to 4550 g/m2 on the wet mud did not kill all of the spores. Treatment of simulated earthen ponds with up to 1200 p.p.m. chlorine did not kill all of...
Tests for association of transferrin and lactate dehydrogenase phenotypes with weight gain in rainbow trout (Salmo gairdneri)
G. L. Reinitz
1977, Journal of the Fisheries Research Board of Canada (34) 2333-2337
Transferrin (Tf) phenotype was associated with weight gain in 147- and 230-day-old rainbow trout, but no association was found between lactate dehydrogenase (LDH) phenotype and weight gain. A total of 2038 progeny were examined from two different environments. Progeny lots were reared at densities below those known to affect mean...
Effect on tricaine methanesulfonate (MS-222) on hematocrit values in rainbow trout (Salmo gairdneri)
G. L. Reinitz, J. Rix
1977, Comparative Biochemistry and Physiology, Part C: Comparative Pharmacology (56) 115-116
1. Anesthesia of rainbow trout (Salmo gairdneri) with 70 ppm tricaine methanesulfonate (MS-222) for 3-9 min resulted in a linear increase in hematocrit.2. Handling of unanesthetized trout caused a higher and more variable hematocrit reading than did exposure to MS-222 for up to 3 min.3. The range and standard error...
Interpretation of discordant 40Ar/39Ar age-spectra of mesozoic tholeiites from Antarctica
R.J. Fleck, J. F. Sutter, D.H. Elliot
1977, Geochimica et Cosmochimica Acta (41) 15-32
Conventional K-Ar ages of tholeiitic basalts of the Ferrar Group in the central Transantarctic Mountains indicate significant loss of radiogenic 40Ar from this unit over much of its outcrop area. Argon loss varies inversely with amount of devitrified matrix in the basalts, which have not been thermally or tectonically disturbed since...

Terrestrial analogs of the Hellespontus dunes, Mars
C. S. Breed
1977, Icarus (30) 326-340
Geomorphic features in the Hellespontus region, Mars, were compared with dunes of the crescentic ridge type in numerous terrestrial sand seas quantitatively by dimensional analysis of dune lengths, widths, and wavelengths. Mean values for the Hellespontus dunes are close to mean values derived from measurements of all sampled terrestrial sand...
A method and fortran program for the computerized reconstruction of three-dimensional objects from serial sections
J.C. Tipper
1977, Computers & Geosciences (3) 579-599
Three-dimensional objects can be reconstructed automatically from sets of serial sections by using a suitable algorithm. For two-phase systems it is sufficient to match phase boundary loops between adjacent sections. When all possible neighboring pairs of sections have been compared in this manner, the bounding surfaces of the object are...

J. H. Christie, J.A. Turner, R. A. Osteryoung
1977, Analytical Chemistry (49) 1899-1903
The theoretical aspects of square wave voltammetry at the dropping mercury electrode are presented. The technique involves scanning the entire potential range of interest on a single drop of a DME. Asymmetries in the waveform as well as variations in current measurement parameters are discussed. Indications are that previous uses...
Orientale and Caloris
J.F. McCauley
1977, Physics of the Earth and Planetary Interiors (15) 220-250
Applications of experimental explosion-crater data to Orientale and recent geologic mapping of the basin have produced a new stratigraphy and genetic model for Orientale that are also applicable to Caloris. The inner-basin scarp of Orientale is thought to be a bench separating the upper parts of the basin from its...

M. E. Beck Jr., S.D. Sheriff, J. F. Diehl, E.A. Hailwood, P. W. Lipman
1977, Earth and Planetary Science Letters (37) 124-130
Combining paleomagnetic data for 17 new sites from the northwest portion of the (Oligocene) San Juan volcanic field of southern Colorado with data for 29 sites previously published yields a paleomagnetic pole at 85°N, 114°E (with a 95% confidence circle of...

N.L. Nehring, P.A. Bowen, A.H. Truesdell
1977, Geothermics (5) 63-66
The fractionation of oxygen isotopes between dissolved sulfate ions and water provides a useful geothermometer for geothermal waters. The oxygen isotope composition of dissolved sulfate may also be used to indicate the source of the sulfate and processes of formation. The methods described here for separation, purification and reduction of...
