Common, ubiquitous species and rare species had little classificatory value and were eliminated from the data set used to derive the avian associations. Initial statistical division of the plots likely reflected structure of the dominant plant species used for nesting; later divisions probably were related to foraging or nesting cover requirements based on vegetation height or density, habitat heterogeneity, or possibly to the existence of mutually similar distributions or shared areas of greater than average abundance for certain groups of species. Knowledge of the effects of grazing, mostly by cattle, on habitat use by the breeding bird species was used to interpret the results of the indicator species analysis.

In support of this goal, a five-step digital convolution procedure has been used to produce directionally enhanced images, which contain few artifacts and little noise. The main limitation of this procedure is that little enhancement of lineaments occurs in dissected terrain, in shadowed areas, and in flat areas with a uniform land cover. The directional enhancement procedure can be modified to extract edge and line segments from an image. Any of various decision rules can then be used to connect the line segments and to produce a final lineament map. The result is an interpretive map, but one that is based on an objective extraction of lineament components by digital processing. -from Authors","language":"English","usgsCitation":"Moore, G.K., and Waltz, F., 1983, Objective procedures for lineament enhancement and extraction: Photogrammetric Engineering and Remote Sensing, v. 49, no. 5, p. 641-647.","productDescription":"7 p.","startPage":"641","endPage":"647","numberOfPages":"7","costCenters":[{"id":222,"text":"Earth Resources Observation and Science (EROS) Center","active":true,"usgs":true}],"links":[{"id":221230,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"49","issue":"5","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a6a27e4b0c8380cd7401b","contributors":{"authors":[{"text":"Moore, G.

The film coefficient is a function of windspeed and water temperature. The dependence of the coefficient on windspeed is determined from published information on the evaporation of water from a canal. The dependence of the coefficient on temperature is determined from laboratory studies on the evaporation of water. Procedures for adjusting the coefficients for different organic solutes are based on the molecular diffusion coefficient and the molecular weight. The molecular weight procedure is easiest to use because of the availability of molecular weights. However, the theoretical basis of the procedure is questionable. The diffusion coefficient procedure is supported by considerable data. Questions, however, remain regarding the exact dependence of the film coefficint on the diffusion coefficient. It is suggested that the diffusion coefficient procedure with a 0.68-power dependence be used when precise estimate of the gas-film coefficient are needed and that the molecular weight procedure be used when only approximate estimates are needed.","language":"English","publisher":"ASCE","doi":"10.1061/(ASCE)0733-9372(1983)109:5(1111)","usgsCitation":"Rathbun, R.E., and Tai, D.Y., 1983, Gas-film coefficients for streams: Journal of Environmental Engineering, v. 109, no. 5, p. 1111-1127, https://doi.org/10.1061/(ASCE)0733-9372(1983)109:5(1111).","productDescription":"17 p.","startPage":"1111","endPage":"1127","numberOfPages":"17","costCenters":[{"id":589,"text":"Toxic Substances Hydrology Program","active":true,"usgs":true}],"links":[{"id":221518,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"109","issue":"5","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a14dce4b0c8380cd54bd5","contributors":{"authors":[{"text":"Rathbun, R.

We have been using electron (EPMA) and proton (PIXE) microprobe analytical methods to obtain data on the chemical characteristics of specific coal constituents in their original associations within coal samples. The present study is aimed at evaluation of the nature of mineral occurrences and heterogeneous elemental concentrations within vitrinites.

The four soil chronosequences, developed primarily on sandy deposits, have some numeric age control and are located in xeric-inland (Merced, Calif.), xeric-coastal (Ventura, Calif.), aridic (Las Cruces, N. Mex.), and udic (Susquehanna Valley, Pa.) soil-moisture regimes. To quantify field properties, points are assigned for developmental increases in soil properties in comparison to the parent material. Currently ten soil-field properties are quantified and normalized for each horizon in a given chronosequence, including two new properties for carbonate-rich soils in addition to the eight properties previously defined. When individual properties or the combined indexes are plotted as a function of numeric age, rates of soil development can be compared in different climates. The results demonstrate that (1) the Soil Development Index can be applied to very different soil types, (2) many field properties develop systematically in different climatic regimes, (3) certain properties appear to have similar rates of development in different climates, and (4) the Profile Index that combines different field properties increases significantly with age and appears to develop at similar rates in different climates.

U-Th-Pb isotopic ratios were determined for two size fractions of zircon inclusions from each mineral, plus five size fractions from the bulk rock. Isotopic data from the inclusions have more than double the spread of data on a discordia obtained from the bulk sample, thereby yielding better-resolved concordia intercepts. However, isotopic ratios and morphologic characteristics indicate that the Pb/U systematics are complicated by inherited radiogenic lead. Although the data array cannot unequivocally be explained by the armoring process, the proposed methodology has succeeded in identifying groups of zircon with different isotopic characteristics. As such, this technique can be used to decipher complex geologic/isotopic histories and may be a useful addition to routine zircon geochronology. ?? 1983 Springer-Verlag.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Contributions to Mineralogy and Petrology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisherLocation":"Springer-Verlag","doi":"10.1007/BF00371194","issn":"00107999","usgsCitation":"Aleinikoff, J.N., 1983, U-Th-Pb systematics of zircon inclusions in rock-forming minerals: A study of armoring against isotopic loss using the Sherman Granite of Colorado-Wyoming, USA: Contributions to Mineralogy and Petrology, v. 83, no. 3-4, p. 259-269, https://doi.org/10.1007/BF00371194.","startPage":"259","endPage":"269","numberOfPages":"11","costCenters":[],"links":[{"id":205055,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1007/BF00371194"},{"id":220703,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"83","issue":"3-4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505bb9e0e4b08c986b327e8e","contributors":{"authors":[{"text":"Aleinikoff, J.

Varve thickness in Skilak Lake is sensitive to annual temperature and snowfall because Skilak Glacier, the dominant source of sediment for Skilak Lake, is sensitive to these climatic parameters. Trends of varve thickness are well correlated with trends of mean annual cumulative snowfall (r = -0.902) of the southern Alaska climatological division and with trends of mean annual temperature of the southern (r = 0.831) and northern (r = 0.786) Alaska climatological divisions. Trends of varve thickness also correlate with trends of annual temperature in Seattle and North Head, Washington (r = 0.632 and 0.850, respectively). Comparisons of trends of varve thickness with trends of annual temperature in California, Oregon, and Washington suggest no widespread regional correlation. Trends of annual snowfall in the southern Alaska climatological division and trends of annual temperature in the southern and northern Alaska climatological divisions are reconstructed for the years 1700-1906 A.D. Climatic reconstructions on the basis of varve thickness in Skilak Lake utilize equations derived from the regression of series of smoothed climatological data on series of smoothed varve thickness. Reconstruction of trends of mean annual cunulative snowfall in the southern Alaska climatological division suggests that snowfall during the 1700s and 1800s was much greater than that during the early and mid-1900s. The periods 1770-1790 and 1890-1906 show marked decreases in the mean annual snowfall. Reconstructed trends of the annual temperature of the northern and southern Alaska climatological divisions suggest that annual temperatures during the 1700s and 1800s were lower than those of the early and mid-1900s. Two periods of relatively high annual temperatures coincide with the periods of low annual snowfall thus determined. ?? 1983.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Quaternary Research","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Elsevier","publisherLocation":"Amsterdam, Netherlands","doi":"10.1016/0033-5894(83)90015-7","issn":"00335894","usgsCitation":"Perkins, J., and Sims, J., 1983, Correlation of Alaskan varve thickness with climatic parameters, and use in paleoclimatic reconstruction: Quaternary Research, v. 20, no. 3, p. 308-321, https://doi.org/10.1016/0033-5894(83)90015-7.","startPage":"308","endPage":"321","numberOfPages":"14","costCenters":[],"links":[{"id":266560,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/0033-5894(83)90015-7"},{"id":221039,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"20","issue":"3","noUsgsAuthors":false,"publicationDate":"2017-01-20","publicationStatus":"PW","scienceBaseUri":"5059fc2ee4b0c8380cd4e175","contributors":{"authors":[{"text":"Perkins, J.A.","contributorId":49769,"corporation":false,"usgs":true,"family":"Perkins","given":"J.A.","email":"","affiliations":[],"preferred":false,"id":360899,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Sims, J.D.","contributorId":9230,"corporation":false,"usgs":false,"family":"Sims","given":"J.D.","email":"","affiliations":[],"preferred":false,"id":360898,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

Barnes, Emeritus Professor of Physics at the University of Texas, El Paso, and a creationist, argues that the geomagnetic field was created by unknown processes at the time of creation of the earth and has been decaying irreversibly and exponentially, with a half-life of about 1400 years, since then. He calculates that the field would have been impossibly large in 8000 B.C. and concludes that the earth, therefore, is less than 10,000 years old. He denies that the earth's field has reversed polarity in the past, and attempts to refute the dynamo theory of the origin of the field. Barnes' arguments and conclusions are commonly cited in creationist literature as definitive proof that the earth is very young. Barnes is wrong, and has ignored or misrepresented much of the data on the earth's magnetic field.</p><p>Barnes calculations are based on observatory measurements showing that the earth's dipole field strength has decreased since 1835. But these same measurements also show a corresponding increase in the strength of the nondipole field so that the total field energy external to the core has remained about constant. Paleomagnetic evidence shows that the earth's field has existed for more than three billion years, and that the dipole field both fluctuates in strength and irregularly reverses polarity. The earth's field is generated by a fluid dynamo in the iron-nickel core; all of the elements necessary for a dynamo, including fluid motion and energy sources, are present. Contrary to Barnes' assertions, there are no theoretical reasons why a dynamo cannot exist in the earth.</p><p class=\"last\">There are no properties of the magnetid field that can be used to place an upper limit on the earth's age.</p>","language":"English","publisher":"Taylor & Francis","doi":"10.5408/0022-1368-31.2.124","issn":"00221368","usgsCitation":"Dalrymple, G.B., 1983, Can the earth be dated from decay of its magnetic field?.: Journal of Geological Education, v. 31, no. 2, p. 124-133, https://doi.org/10.5408/0022-1368-31.2.124.","productDescription":"10 p.","startPage":"124","endPage":"133","numberOfPages":"10","costCenters":[],"links":[{"id":480230,"rank":2,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.5408/0022-1368-31.2.124","text":"Publisher Index Page"},{"id":220974,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"31","issue":"2","noUsgsAuthors":false,"publicationDate":"2018-02-13","publicationStatus":"PW","scienceBaseUri":"5059f33be4b0c8380cd4b69b","contributors":{"authors":[{"text":"Dalrymple, G.

The resulting factors will be expressed in measures determined by the form of the scalings that have been applied to the original data matrix. Unless the measures for both solutions are meaningful for the problem at hand, the factor results may be misleading or uninterpretable. Correspondence analysis uses a symmetrical scaling of both rows and columns to achieve measures of proportional similarity between objects and variables. In the literature, the resulting similarity is a ??2distance appropriate for analysis of enumerated data, the original application of correspondence analysis. Justification for the use of this measure with interval or ratio data is unconvincing, but a minor modification of the scaling procedure yields the profile similarity, which is an appropriate measure. Symmetrical scaling of rows and columns is unnecessary for RQ-mode factor analysis. If the data are scaled so the minor product W'W is the correlation matrix, the major product WW'is expressed in the Euclidean distances between objects. Therefore, RQ-mode factor analysis can be performed so that the R mode is a principal components solution and the Q mode is a principal coordinates solution. For applications where the magnitudes of differences are important, this approach will yield more interpretable results than will correspondence analysis. ?? 1983 Plenum Publishing Corporation.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of the International Association for Mathematical Geology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisherLocation":"Kluwer Academic Publishers-Plenum Publishers","doi":"10.1007/BF01093413","issn":"00205958","usgsCitation":"Zhou, D., Chang, T., and Davis, J., 1983, Dual extraction of R-mode and Q-mode factor solutions: Journal of the International Association for Mathematical Geology, v. 15, no. 5, p. 581-606, https://doi.org/10.1007/BF01093413.","startPage":"581","endPage":"606","numberOfPages":"26","costCenters":[],"links":[{"id":205107,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1007/BF01093413"},{"id":221284,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"15","issue":"5","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a0406e4b0c8380cd5074a","contributors":{"authors":[{"text":"Zhou, D.","contributorId":98037,"corporation":false,"usgs":true,"family":"Zhou","given":"D.","email":"","affiliations":[],"preferred":false,"id":360935,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Chang, T.","contributorId":37067,"corporation":false,"usgs":true,"family":"Chang","given":"T.","email":"","affiliations":[],"preferred":false,"id":360933,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Davis, J.C.","contributorId":72121,"corporation":false,"usgs":true,"family":"Davis","given":"J.C.","email":"","affiliations":[],"preferred":false,"id":360934,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

A group of elements based on known or suspected association in altered or mineralized areas is selected for study and the anomaly scores for these elements are summed for each sample site and then plotted on a map. Some of the results of geochemical studies conducted for mineral assessments in two areas are briefly described. The first area, the Mokelumne Wilderness and vicinity, is a relatively small and geologically simple one. The second, the Walker Lake 1° × 2° quadrangle, is a large area that has extremely complex geology and that contains a number of different mineral deposit environments.

In addition, there are significant variations in travel time patterns, depending on the azimuth of wave arrivals. Two simple modeling approaches have been used to infer the upper mantle velocity structure from the observed variations in travel time.

In the second modeling approach, a fixed velocity contrast is assumed between the lithosphere and asthenosphere with variations in travel time resulting from variations in lithospheric thickness.

The process of dedolomitization consists of dolomite dissolution and concurrent precipitation of calcite; it is driven by dissolution of gypsum.</p><p>Deuterium and oxygen isotopic data from the ground water, coupled with regional potentiometric maps, show that recharge occurs on the western slope of the Black Hills and that the water flows northward and westward toward the Powder River Basin. A significant part flows around the southern end of the Black Hills to replenish the aquifer to the east of the Hills. Depth of flow was inferred from interpretation of the silica geothermometer based on the temperature-dependent solubilities of quartz and chalcedony in water. Chemical effects of warm water in the Pahasapa Limestone include changes in the solubility products of minerals, conversion of gypsum to anhydrite, solution and precipitation of minerals, and increases in the tendency for outgassing of carbon dioxide. Where sulfate reduction is not important, sulfur isotope data show that (1) in the Mississippian aquifer, most of the sulfate is from dissolution of gypsum and (2) some wells and springs have a hydrologic connection with overlying Permian and Pennsylvanian evaporites. Sulfate ion concentration, a progress variable, shows a strong correlation with pH as a result of the combined effects of the dedolomitization reactions.</p><p>Mass-balance and mass-transfer calculations were used to adjust<span>&nbsp;</span><sup>14</sup>C values to determine a range of ground-water flow velocities between 2 and 20 m/yr.
