These water uses have continued to increase with growth in population and land development. Diversion of flow from channels, storage of water in reservoirs, and increased use of ground water have affected the distribution and timing of streamflows and the transport of fluvial sediments. All these factors have contributed to changes in channel geometry and the riverine environment.\r\n\r\nIn 1979, the U.S. Geological Survey began investigations in the Platte River basin to determine the effects of water use on the hydrology and morphology of the Platte River and its major tributaries. These investigations also considered the relationship of hydrologic regime to factors that control or affect the habitat of migratory waterfowl in the Platte River valley.\r\n\r\nThis volume brings together the results of several research studies on historical changes in channel morphology, surface-water hydrology, hydraulic geometry, sediment-transport and bedform processes, ground-water and surface-water relations, stochastic models of streamflow and precipitation, and methods for estimating discharge required to maintain channel width. In each of the studies, data on some segment of the Platte River hydrologic system were collected and interpreted. All the studies are interrelated; together they provide some degree of understanding of regime changes that are occurring. The hydrologic research described in the following chapters will be useful in decision-making pertaining to the management of water resources and migratory waterfowl habitats.","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/pp1277","usgsCitation":"Water Resources Division, U.S. Geological Survey, 1983, Hydrologic and geomorphic studies of

The cellophane transfer and agar plug transfer techniques had similar reliability and reproducibility in rating fungicidal activity, and were both superior to the agar dilution technique. The agar plug transfer and agar dilution techniques adequately projected in vivo activity of malachite green, but the cellophane transfer technique overestimated its activity.

Historically, many small oil and gas fields went unreported because they were not economical. This led to an underestimation of the number of undiscovered small fields. A study of the distributions of reported oil and gas fields in well-explored areas suggests that the large fields when grouped into log base 2 size classes are geometrically distributed. Further, the number of small fields reported is a function of the cost of exploration and development. Thus, the population field-size distribution is conjectured to be log geometric in form. ?? 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/BF01030080","issn":"00205958","usgsCitation":"Schuenemeyer, J., and Drew, L., 1983, A procedure to estimate the parent population of the size of oil and gas fields as revealed by a study of economic truncation: Journal of the International Association for Mathematical Geology, v. 15, no. 1, p. 145-161, https://doi.org/10.1007/BF01030080.","startPage":"145","endPage":"161","numberOfPages":"17","costCenters":[],"links":[{"id":205127,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1007/BF01030080"},{"id":221535,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"15","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059e50ce4b0c8380cd46ac5","contributors":{"authors":[{"text":"Schuenemeyer, J.H.","contributorId":106094,"corporation":false,"usgs":true,"family":"Schuenemeyer","given":"J.H.","affiliations":[],"preferred":false,"id":361468,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Drew, L.J.","contributorId":69157,"corporation":false,"usgs":true,"family":"Drew","given":"L.J.","email":"","affiliations":[],"preferred":false,"id":361467,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

Present ELAs rise from south to north across the Himalayan Range from 5200 to 5800 m, as indicated by the altitudes of lowest cirque glaciers and highest lateral and medial moraines on valley glaciers. In contrast, ELAs during maximum late Pleistocene glaciation rose in altitude from 4300 to 5500 m across the range, as indicated by altitudes of lowest cirque floors and maximum extent of glacial deposits. Highest ELAs occurred on previously unrecognized ice caps that formerly covered extensive highland areas in Tibet north of the range crest. During four distinct Holocene glacial advances of subequal magnitude, ELAs were depressed about 30% as much as the late Pleistocene maximum depression. Depression of ELAs during the late Pleistocene glaciation was about twice as great south of the range crest (950 m) as north of it (400 m). Although the present northward decrease in precipitation causes ELAs to rise northward for 85 km at 7.1 m km<sup>-1</sup>, the gradient during maximum late Pleistocene glaciation was 11 m km<sup>-1</sup>. Such a great contrast in glacier response to climate change over a short distance is remarkable and probably reflects increased aridity on the Tibetan Plateau and increased climatic contrast across the Himalayan Range during glacial ages.</span></p>","language":"English","publisher":"INSTAAR, University of Colorado","doi":"10.2307/1550922","usgsCitation":"Williams, V.S., 1983, Present and former equilibrium-line altitudes near Mount Everest, Nepal and Tibet: Arctic and Alpine Research, v. 15, no. 2, p. 201-211, https://doi.org/10.2307/1550922.","productDescription":"11 p.","startPage":"201","endPage":"211","costCenters":[],"links":[{"id":220891,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"Nepal, Tibet","otherGeospatial":"Mount Everest","volume":"15","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a8b44e4b0c8380cd7e1d8","contributors":{"authors":[{"text":"Williams, V.

The consequences and timing of these events can be observed in variations in the distribution of deep-sea hiatuses, sedimentation patterns, and biogeographic distribution of planktic organisms.</p><p>The opening of the Drake Passage in the latest Oligocene to early Miocene (25–20 Ma) resulted in the establishment of the deep circumpolar current, which led to thermal isolation of Antarctica and increased global cooling. This development was associated with a major turnover in planktic organisms, resulting in the evolution of Neogene assemblages and the eventual extinction of Paleogene assemblages. The erosive patterns of two widespread hiatuses (PH, 23.0–22.5 Ma; and NH 1, 20–18 Ma) indicate that a deep circumequatorial circulation existed at this time, characterized by a broad band of carbonate-ooze deposition. Siliceous sedimentation was restricted to the North Atlantic and a narrow band around Antarctica.</p><p>A major reorganization in deep-sea sedimentation and hiatus distribution patterns occurred near the early/middle Miocene boundary, apparently resulting from changes in oceanic circulation. Beginning at this time, deep-sea erosion occurred throughout the Caribbean (hiatus NH 2, 16–15 Ma), suggesting disruption of the deep circumequatorial circulation and northward deflection of deep currents, and/or intensification of the Gulf Stream. Sediment distribution patterns changed dramatically with the sudden appearance of siliceous-ooze deposition in the marginal and east equatorial North Pacific by 16.0 to 15.5 Ma, coincident with the decline of siliceous sedimentation in the North Atlantic. This silica switch may have been caused by the introduction of Norwegian Overflow Water into the North Atlantic acting as a barrier to outcropping of silica-rich Antarctic Bottom Water.</p><p>The main aspects of the present oceanic circulation system and sediment distribution pattern were established by 13.5 to 12.5 Ma (hiatus NH 3), coincident with the establishment of a major East Antarctic ice cap.

Freshwater fishes of Arroyo Colorado, a major waterway traversing the lower Rio Grande Valley, were highly contaminated with DDE and toxaphene residues compared to samples from other areas in the Valley; both DDE and toxaphene ranged up to 31.5 ppm wet wt in whole-fish composite samples. Median DDE residues in fish-eating bird carcasses from this area ranged up to 34 ppm wet wt, and 81 ppm in individual specimens. The levels of contaminants detected in fishes and birds were within, or above, the range producing adverse effects in certain species. The major sources of contamination to the Arroyo Colorado system likely stem from past and present use of persistent pesticides on surrounding croplands, and possibly from an abandoned pesticide plant at Mission, Texas.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Southwestern Naturalist","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"U.S. Fish and Wildlife Service","usgsCitation":"White, D.H., Mitchell, C.A., Kennedy, H., Krynitsky, A.J., and Ribick, M.A., 1983, Elevated DDE and toxaphene residues in fishes and birds reflect local contamination in the lower Rio Grande valley Texas USA: Southwestern Naturalist, v. 28, no. 3, p. 325-334.","productDescription":"pp. 325-334","startPage":"325","endPage":"334","numberOfPages":"10","costCenters":[{"id":606,"text":"Upper Midwest Environmental Sciences Center","active":true,"usgs":true}],"links":[{"id":173240,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"28","issue":"3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a1be4b07f02db606ea2","contributors":{"authors":[{"text":"White, Donald H.","contributorId":97868,"corporation":false,"usgs":true,"family":"White","given":"Donald","email":"","middleInitial":"H.","affiliations":[],"preferred":false,"id":312971,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Mitchell, C.

Correlatives are known in Texas. The shale is regionally known by a number of names: Chattanooga, Dunkirk, Rhinestreet, Huron, Antrim, Ohio, Woodford, etc. These shales, other than those in Texas, have elicited much interest because they have been a source of unassociated natural gas. It is of particular interest, however, that most of these shales have no associated crude oil, in spite of the fact that they have some of the characteristics normally attributed to source beds. This paper addresses some of the organic geochemical aspects of the kerogen in these shales, in relation to their oil generating potential. Past organic geochemical studies on Eastern Devonian shales will be reviewed. Recent solid state 13C NMR studies on the nature of the organic matter in Eastern Devonian shales show that Eastern Devonian shales contain a larger fraction of aromatic carbon in their chemical composition. Thus, despite their high organic matter contents, their potential as a petroleum source rock is low, because the kerogen in these shales is of a \"coaly\" nature and hence more prone to producing natural gas.","largerWorkTitle":"Preprints Symposia","language":"English","issn":"05693799","usgsCitation":"Breger, I.A., Hatcher, P.G., Romankiw, L., and Miknis, F., 1983, Eastern Devonian shales: Organic geochemical studies, past and present, <i>in</i> Preprints Symposia, v. 28, no. 1.","startPage":"73","costCenters":[],"links":[{"id":221803,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"28","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a0532e4b0c8380cd50cd0","contributors":{"authors":[{"text":"Breger, Irving A.","contributorId":65205,"corporation":false,"usgs":true,"family":"Breger","given":"Irving","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":362730,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Hatcher, Patrick G.","contributorId":93625,"corporation":false,"usgs":true,"family":"Hatcher","given":"Patrick","email":"","middleInitial":"G.","affiliations":[],"preferred":false,"id":362732,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Romankiw, L.A.","contributorId":85724,"corporation":false,"usgs":true,"family":"Romankiw","given":"L.A.","affiliations":[],"preferred":false,"id":362731,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Miknis, F.P.","contributorId":61564,"corporation":false,"usgs":true,"family":"Miknis","given":"F.P.","email":"","affiliations":[],"preferred":false,"id":362729,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

Functional relationships are derived for obtaining the trajectory from the spatial distribution of velocity and for obtaining the velocity distribution from the trajectory. It is established that the trajectory end-points impose only an integral condition on the velocity distribution, and that no individual point on the velocity distribution can be determined if only the end-points are known. An example is given of a deduced velocity distribution that is consistent with (although not uniquely determined by) the end-points of several trajectories on the lower reach of Columbia Glacier, Alaska. It is shown that constructing a velocity distribution by assigning the average trajectory velocity to the trajectory mid-point can be subject to errors of several per cent for velocity distribution features that are typical of actual glaciers. The error in this method is determined, and closed-form expressions for the trajectory are obtained, for linear velocity distributions and for two classes of second-degree distributions. The class of functions is identified to which the velocity distribution must belong for this error to be zero.</p></div></div>","language":"English","publisher":"Cambridge University Press","doi":"10.3189/S0022143000008261","issn":"00221430","usgsCitation":"Rasmussen, L.A., 1983, Calculation of a velocity distribution from particle trajectory end-points.: Journal of Glaciology, v. 29, no. 102, p. 203-214, https://doi.org/10.3189/S0022143000008261.","productDescription":"12 p.","startPage":"203","endPage":"214","numberOfPages":"12","costCenters":[],"links":[{"id":480226,"rank":2,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.3189/s0022143000008261","text":"Publisher Index Page"},{"id":222695,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"29","issue":"102","noUsgsAuthors":false,"publicationDate":"2017-01-20","publicationStatus":"PW","scienceBaseUri":"5059f2ffe4b0c8380cd4b537","contributors":{"authors":[{"text":"Rasmussen, Lowell A.","contributorId":36930,"corporation":false,"usgs":true,"family":"Rasmussen","given":"Lowell","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":362697,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

Sagebrush clippings were separated into two subsamples consisting of (1) stems, and (2) leaves and blossoms stripped from the stems. These subsamples were ashed separately and the ash analyzed with an emission spectrograph for 30 elements. There appear to be no appreciable differences in the analyses of the two subsamples, indicating that composite samples would provide adequate information for further investigations. Eight of these elements, Ag, Bi, Cu, Pb, Sn, Y, Zn, and Zr, are present in notably higher concentrations in the ash of samples growing over mineralized ground than in that of control samples growing over barren ground. Although the distribution pattern, and the number of these anomalous elements, differs at each of the five localities, three of them, silver, copper, and lead, show good contrast and close association with subjacent mineralization in all five study areas.</span></p>","language":"English","publisher":"Elsevier","doi":"10.1016/0375-6742(83)90069-9","issn":"03756742","usgsCitation":"Lovering, T., and Hedal, J.A., 1983, The use of sagebrush (Artemisia) as a biogeochemical indicator of base-metal deposits in Precambrian rocks of west-central Colorado: Journal of Geochemical Exploration, v. 18, no. 3, p. 205-230, https://doi.org/10.1016/0375-6742(83)90069-9.","productDescription":"26 p.","startPage":"205","endPage":"230","numberOfPages":"26","costCenters":[],"links":[{"id":221520,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"18","issue":"3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505bb196e4b08c986b325355","contributors":{"authors":[{"text":"Lovering, T.G.","contributorId":55014,"corporation":false,"usgs":true,"family":"Lovering","given":"T.G.","affiliations":[],"preferred":false,"id":360970,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Hedal, J.
