Five of these (A through E), present in western central Arizona, are marine deposits containing the trace fossil Corophioides; several intertidal environments are represented. The association of large-scale cross-bedding (50 to 300 cm) that is characterized by compound cross-stratification, numerous reactivation surfaces, and herringbone patterns is typical of facies A and generally typical of the finer-grained, thinner-bedded facies B. The sedimentary structures and polymodal distribution of foreset azimuths common to facies A and B probably formed on intertidal sand bars during emergence and late-stage tidal runoff. Facies C consists of well-sorted sandstone, gently cross stratified or with continuous parallel stratification, and foresets tangential to the lower bedding surface. This facies generally occurs where the gradient of the depositional surface increases; it apparently was deposited on a beach by shoaling waves. Facies D and, to a lesser extent, the coarser-grained facies E are sandstones with trough cross-stratification, fining-upward cycles, abundant intercalated thin shale and sandstone, rare flaser bedding, and local bipolar distribution of foreset azimuths. Both facies are tidal flat deposits; facies D was probably produced by meandering tidal channels, whereas facies E was likely produced by migration of braided tidal channels. The sixth facies (F), present in eastern central Arizona, is an arkosic small-pebble conglomerate that lacks trace fossils; low dispersion of foreset azimuths and large-scale (1 to 11-m wide) cut-and-fill structure are typical. Facies F was deposited by bedload streams that transported coarse, poorly sorted sand and gravel westward to the intertidal flats.

The hydrocarbons were identified in the near-bottom waters downcurrent for more than 100 kilometers from a sea-floor point source. Preliminary dynamic modeling estimates of the initial gas phase composition predict methane/ethane and ethane/propane ratios of 24 and 1.7, respectively, assuming the hydrocarbons were introduced by bubbles. The low ethane/propane ratio is indicative of gas from a liquid petroleum source rather than from nonassociated or biogenic natural gas. Preliminary data on the structural geology of Norton Basin lend support to the interpretation based on the hydrocarbon plume. Unconformably truncated strata dip basinward from the seep locus; acoustic anomalies and numerous steeply dipping faults in the immediate vicinity of the seep are corroborating evidence that shallow gas- or petroleum-charged sediments and strata coincide with avenues for migration of mobile hydrocarbons to the sea floor. These factors, taken in concert with the sedimentological regime, the recent revision (increase) of basin depth estimates, and the highly localized hydrocarbon source, strongly suggest a thermogenic rather than a recent biogenic origin for these gaseous compounds.

The first winter (1972–1973) five plasma enzymes known to respond to organochlorine poisoning were examined. Abnormal enzyme elevations suggested that 20% of the population sampled (23/115 ducks) might contain organochlorine contaminants, but no residue analyses were performed. The second winter (1974) two of the same enzymes, aspartate aminotransferase and lactate dehydrogenase, and a third enzyme known to be specifically inhibited by lead, delta-aminolevulinic acid dehydratase, were assayed in 95 blood samples. Blood residues of organochlorine compounds and of lead were determined in representative samples, and the correlations between residue levels and enzyme changes were examined.
The enzyme bioassays in 1974 indicated that lead was a more prevalent environmental contaminant than organochlorine compounds in canvasback ducks; 17% of the blood samples had less than one-half of the normal delta-aminolevulinic acid dehydratase activity, but only 11% exhibited abnormal aspartate aminotransferase or lactate dehydrogenase activities. These findings were confirmed by residue analyses that demonstrated lead concentrations four times higher than background levels, but only relatively low organochlorine concentrations. There was a highly significant inverse correlation between delta-aminolevulinic acid dehydratase activity and blood lead concentrations (P<0.01), and a weaker but significant correlation between plasma aspartate aminotransferase activity and blood PCB concentrations (P<0.05).
It was apparent that delta-aminolevulinic acid dehydratase activity in the blood provided a sensitive and precise estimate of lead contamination in waterfowl. In canvasback ducks 200 ppb of lead in the blood caused a 75% decrease in delta-aminolevulinic acid dehydratase activity, a magnitude of enzyme inhibition that disturbs heme synthesis and is regarded as detrimental in humans.

Excellent protection was evident against experimentally induced vibriosis in the groups immunized by HI with 10 × Hanks' balanced salt solution (HBSS), 1 × HBSS with 8.0% NaCl and 5.3% NaCl, as well as in the injected groups. Comparisons were made among the various immunization methods by vaccinating fish with ten-fold serial dilutions of bacterin, then challenging them by the water contact method after 6 or 9 weeks.

The main method was aerial radio-tracking of 129 wolves and their packmates. Due to a decline in white-tailed deer (Odocoileus virginianus), the wolf population decreased during most of the study. Average annual productivity varied from 1.5 to 3.3 pups per litter, and annual mortality rates from 7 to 65 percent. Malnutrition and intraspecific strife accounted equally for 58 percent of the mortality; human causes accounted for the remainder. As wolf numbers began to decline, pup starvation became apparent, followed by lower pup production, and then by increased intraspecific strife. At higher densities, adult pack wolves were the most secure members of the population, but as the population declined, they became the least secure because of intraspecific strife.

Numerous scientific field parties have viewed or visited the locality and published short accounts of their observations. The river bluffs are as much as 90 meters high and are composed of Tertiary lignite-rich sedimentary rocks and frozen Quaternary sand, silt, and gravel. Resampling and analysis of pollen show that the Tertiary rocks are Miocene rather than Miocene and Pliocene as previously thought. The Miocene flora, possessing a number of conifer and hardwood-tree types, was more varied than the present vegetation and indicates a warmer and wetter climate than at present. The area is frequently referred to as the boneyard because of the common occurrence of large bones of Pleistocene mammals within the frozen silts.

Benthonic foraminiferal assemblages from eight stratigraphic sections range in age from Ynezian to possible basal Refugian. The Paleocene mudstone contains a Ynezian benthonic foraminiferal assemblage. The Ulatisian benthonic assemblage of the Lucia Mudstone and the Penutian to Ulatisian benthonic assemblages of the Eocene sandstone and rnudstone unit are associated with planktonic foraminifers referable to Zones P 7-P 8 and P 9. The Church Creek Formation is characterized by a Narizian to possibly Refugian benthonic assemblage. Two questionable associations of early Eocene planktonic foraminifers with Narizian benthonic foraminifers occur near Arroyo Seco Creek. No -age-diagnostic foraminifers were found in The Rocks Sandstone. Data from previous studies, along with our data, suggest a Ulatisian to Narizian age for this unit. Paleoenvironments interpreted from foraminiferal assemblages suggest a general shoaling from lower bathyal or deeper water depths in the middle Paleocene and early Eocene to bathyal water depths during the middle Eocene. In addition, the Ulatisian water depths deepen across the Santa Lucia Range from east to west.

The craters have characteristics suitable for reconnaissance-type field investigations. The Schooner test produced a crater about 300 m across and excavated more than 72 m of stratigraphic section deposited in a fairly regular fashion so that systematic observations yield systematic results. Other features common on the Moon, such as secondary craters and glass-coated rocks, are present at Schooner crater. Smaller explosive tests on Buckboard Mesa excavated rocks from three horizontal alteration zones within basalt flows so that the original sequence of the zones could be determined. One crater illustrated the characteristics of craters formed across vertical boundaries between rock units. Although the exercises at the Nevada Test Site were only a small part of the training of the astronauts, voice transcripts of Apollo missions 14, 16, and 17 show that the exercises contributed to astronaut performance on the Moon.

More than two-thirds of the batholith and contiguous wallrocks is gneissic, the gneissosity comprising strong cataclasis and mylonitization, penetrative planar and linear structures, and crystallization of muscovite and biotite in the foliation planes. New radiometric ages indicate that the deformation followed the crystallization of the batholith so closely that the K-Ar dating method cannot distinguish a difference, whereas previously published ages from the gneisses indicate a short time between the two events.

The radiometric ages are based upon studies by K-Ar, Rb-Sr, and fission-track methods. Associated with these alkalic rock complexes are numerous thorium-bearing veins and red syenite dikes; some, if not all, in the northern Wet Mountains were formed about 495 m.y. ago. Diabase, gabbro, and other mafic dikes appear to be slightly younger than the thorium veins in the Powderhorn area and both older and younger in the Wet Mountains region. In the Powderhorn district, an older group of syenites also intruded Precambrian rocks as plugs or small stocks about 1350-1400 m.y. ago. The various dike rocks and the thorium veins were formed in extensive, deep fractures, indicating a condition of tension or shear in this part of the crust during Cambrian or very late Precambrian to Ordovician time. The localized alkalic magmatisin may reflect melting spots in the mantle. In the two principal areas, 135 km apart, the episodes of alkalic magmatism differ in age by about 50 m.y., the younger toward the east. The age relations might be explained by migration of the sites of localized melting or volatile enrichment in the mantle or westward movement of the continent above a single site.

Use of the more general equations (adapted from the Bateman equations) is desirable for calculation and interpretation of U-Pb isotope apparent ages of both open and closed systems in the range of 2 to 20 m.y. and is essential for apparent ages less than about 2 m^y. For very young sandstone uranium deposits, a significant uncertainty in the 208Pb/238U systematics may still persist owing to the uncertainty in the initial value of 234U/238U.

During this period, 231 rainfall periods were recorded; 106 were large enough to produce runoff, and 30 were sampled for chemical analyses.
The fraction of rainfall that runs off is low, usually 5 to 10 percent. Several factors which combine to reduce runoff are the large area of pervious lawns (61 percent), the gentle slope of the area, and the use of grassy swales for routing storm water.
Bulk precipitation (rainfall plus dry fallout) quality is good by comparison to that of other metropolitan areas. As a consequence of the low runoff and the low concentrations of the bulk precipitation, loads for this residential area are small. Estimated annual load for chemical oxygen demand was 22.5 kilograms per hectare; total residue, 85.3 kg/ha; total nitrogen, 1.48 kg/ha; and total phosphorus, 0.21 kg/ha.

For steady-state water-table problems plagued by excessive elimination of grid blocks during the iteration process, selection of β<1 can be effective in limiting the deletion of blocks to a reasonable number. Also, a linear problem characterized by large anisotropy and layers of contrasting hydraulic conductivity was solved more efficiently with β=1.5. Effective values of β are generally in the range 0<β<2 and are easily determined by trial. Use of a β parameter in the SIP algorithm provides an effective solution technique for a class of ground-water-flow problems that previously was burdened by significant computational difficulty.

The reliability of such relations and of flow estimates made from them is partly dependent on the user's ability to recognize a suitable reach and the reference levels in that reach. A test was made in northern Wyoming to determine how consistently trained individuals could measure channel size for three different reference levels. Seven participants independently visited 22 sites and measured channel dimensions in sections of their choosing. Assuming that the functional relation between a discharge characteristic (Q) and channel width (W) is log Q=f(1.5 log W) and that the average log W from seven measurements is the best estimate of log W at a site, an average standard error for discharge of about 30 percent was attriluted to differences in width measurements alone.
