In grizzly bears, the high prevalence of this parasite (61% of 254 bears infected), the elevated larval concentrations in sensitive anatomical sites such as the tongue (average, 51 larvae per gram of tissue), and the chronic nature of bear infections as indicated by the tendency for highest infection rates to occur in older age classes (&gt; 16 yrs.), suggest a potential behavior-modifying effect might exist. However, retrospective analysis of recent human attacks by 4 grizzlies and 2 black bears in the northern Rocky Mountain region failed to demonstrate a consistent connection between erratic conduct and levels of<i> Trichinella</i> larvae (trichinae) in bear tissues.

Models of the evolution of planetary surfaces and atmospheres must be reconciled with the diversity, abundance, and origins of channels and valleys on Mars. The term “channel” is properly restricted to those Martian troughs that display at least some evidence of large-scale fluid flow on their floors. Outflow channels show evidence of flows emanating from zones of chaotic terrain. The term “valley” applies to those elongate Martian troughs, or systems of troughs, that also appear to have formed by fluid flow, but which lack a suite of bed forms on their floors. The Martian valleys of greatest interest consist of interconnected, digitate networks that dissect extensive areas of heavily cratered uplands on the planet. The diversity of Martian channels and valleys is nearly as great as that of their terrestrial counterparts. Even though polygenetic and highly modified features abound, water was a necessary ingredient in the various channel- and valley-forming processes. The outflow channels involved large-scale fluid flow, entailing as yet unresolved percentages of liquid and solid phases, entrained sediment, and debris flowage. The formation of valley networks required ground water or ground ice, contributing to sapping and various other hillslope phenomena. Channels and valley networks probably require an ancient epoch with surface temperatures and pressures higher than at present. The aqueous formation of channels is release-limited, requiring short-duration floods of immense volumes. The origin of valley networks is perseverance-limited, requiring the maintenance of prolonged seepage and surface flow. Both phenomena are consistent with a thick, ice-rich Martian permafrost formed either during a volatile-rich early epoch or by very effective recycling of planetary water.</span></p>","language":"English","publisher":"The Geological Society of America","doi":"10.1130/0016-7606(1983)94<1035:CAVOM>2.0.CO;2","usgsCitation":"Mars Channel Working Group, 1983, Channels and valleys on Mars: GSA Bulletin, v. 94, no. 9, p. 1035-1054, https://doi.org/10.1130/0016-7606(1983)94<1035:CAVOM>2.0.CO;2.","productDescription":"20 p.","startPage":"1035","endPage":"1054","costCenters":[{"id":131,"text":"Astrogeology Science Center","active":true,"usgs":true}],"links":[{"id":358669,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"94","issue":"9","noUsgsAuthors":false,"publicationStatus":"PW","contributors":{"authors":[{"text":"Mars Channel Working Group","contributorId":209982,"corporation":true,"usgs":false,"organization":"Mars Channel Working Group","id":749399,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

Analyses regarding grain size and sorting distribution at Great Sand Dunes indicate that the higher dunes contain much more fine-grained sand and much less medium-grained sand than do the lower dunes, and, in addition, they are definitely better sorted. Cross-stratification in eolian deposits is the product of several distinct processes of transport. These processes are saltation or ripple migration that include various amounts of surface creep, grainfall (a dropping of grains from sand in suspension), and avalanching either by mass movement or by grain flowage which involves the downhill rolling or sliding of discrete particles. Penecontemporaneous deformational structures including various types of faults and folds, flames, break aparts, and rotated blocks are sufficiently numerous in most eolian deposits to serve as useful tools in determining genesis. These structures are good indicators of the nature of the stress and therefore provide information on the part of a sand body involved. Sufficient observations have been recorded to establish that the lee side (or slipface) of most modern dunes stands at 30° or slightly more and that the length of the foresets developed on it may be 8 or 10 m and often much more. © 1983, Elsevier Science &amp; Technology.

Modal and normative trends within each pluton are consistent with separation of plagioclase and mafic minerals leading to a residual liquid enriched in quartz and alkali feldspar. The presence of homogeneous cores in the plagioclase, early titanite crystallization in the Red Lake magma and irregular hornblende compositions suggest that refractory material was present when the magmas were intruded.

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

This amount is determined by the characteristics of the environment in which ground-water occurs and by the interactions of ground-water with precipitation, surface water, and people. It should be recognized that quantity and quality of ground-water are intimately related and should be considered accordingly. Quantity refers to usable water and water is usable for any specific purpose only so long as its quality has not deteriorated beyond acceptable limits. Thus an overall quantitative and qualitative management of ground water is inevitable, and its should also involve the uses of ground-water reservoirs for purposes other than water supply. The main objective of ground-water management is to ensure that ground-water resources will be available in appropriate time and in appropriate quantity and quality to meet the most important demands of our society. Traditional, and obvious uses of ground-water are the extraction of water for water supplies (domestic, municipal, agricultural, and industrial) and the natural discharge feeding lakes and maintaining base flow of streams. Not so obvious are the uses of ground-water reservoirs, the very framework within which ground-water occurs and moves, and in which other fluids or materials can be stored. In the last two decades, ground-water reservoirs have been intensively considered for many other purposes than water supplies. Diversified and very often conflicting uses need to be evaluated and dealt with in the most efficient way in order to determine the importance of each possible use, and to assign priorities of these uses. With rising competition for the use of ground-water reservoirs, we will also need to increase the potential for effective planning of ground-water development and protection. Man's development and use of ground-water necessarily modifies the natural conditions and the total natural system must be successfully blended with the unnatural stresses placed upon it. This can be accomplished by introducing new methods (such as ground-water zoning) in and by developing alternative strategies for ground-water management and protection. ?? 1983 D.

Several hundred wells could be in danger of going dry. If irrigation were terminated, leakage from the Dungeness River would become the major source of ground-water recharge.

A persistent decrease of porosity with depth, similar to that of chalks of the Gulf Coast, occurs in these rocks. We make no attempt to differentiate depositional or diagenetic facies which produce scatter in the porosity-depth relationship; the dominant data trends thus are functions of carbonate rocks in general rather than of particular carbonate facies. Carbonate strata with less than 20% porosity are absent from the rocks studied here.</p><p>Aquifers and aquicludes cannot be distinguished on the basis of porosity. Although aquifers are characterized by great permeability and well-developed vuggy and even cavernous porosity in some intervals, they are not exceptionally porous when compared to other Tertiary carbonate rocks in south Florida. Permeability in these strata is governed more by the spacial distribution of pore space and matrix than by the total volume of porosity present.</p><p>Dolomite is as porous as, or slightly less porous than, limestones in these rocks. This observation places limits on any model proposed for dolomitization and suggests that dolomitization does not take place by a simple ion-for-ion replacement of magnesium for calcium. Dolomitization may be selective for less porous limestone, or it may involve the incorporation of significant amounts of carbonate as well as magnesium into the rock.</p><p>The great volume of pore space in these rocks serves to highlight the inefficiency of early diagenesis in reducing carbonate porosity and to emphasize the importance of later porosity reduction which occurs during the burial or late near-surface history of limestones and dolomites.</p>","language":"English","publisher":"American Association of Petroleum

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 first, it is assumed that the velocity variations are distributed throughout a depth range of about 60–160 km.

Superimposed is a west-to-east trend from 7.85 km/s under the Sierra Nevada crest to 7.7 km/s east of Lake Tahoe. 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. One model, consistent with the observations, indicates a thinning of the lithosphere from 110 km at the north end of the Sierra to 60 km near Mono Lake.</span></p>","language":"English","publisher":"American Geophysical Union","doi":"10.1029/JB088iB07p05874","issn":"01480227","usgsCitation":"Mavko, B., and Thompson, G.A., 1983, Crustal and upper mantle structure of the northern and central Sierra Nevada: Journal of Geophysical Research Solid Earth, v. 88, no.

However, within the Loihi suite abundance ratios of geochemically similar elements (Zr/Hf, Nb/Ta and La/Ce) vary by factors of 1.2–1.5 and abundance ratios of highly incompatible elements such as P/Ce, P/Th, K/Rb, Ba/Th and La/Nb vary by factors of 1.2–2.5.

The Bonneville lake cycle began prior to 26,000 yr B.P.; the lake reached the Bonneville shoreline about 16,000 yr B.P. Poor dating control limits our knowledge of the timing of subsequent events. Lake level was maintained at the Bonneville shoreline until about 15,000 yr B.P., or somewhat later, when catastrophic downcutting of the outlet caused a rapid drop of 100 m. The Provo shoreline was formed as rates of isostatic uplift due to this unloading slowed. By 13,000 yr B.P., the lake had fallen below the Provo level and reached one close to that of Great Salt Lake by 11,000 yr B.P. Deposits of the Little Valley lake cycle are identified by their position below a marked unconformity and by amino acid ratios of their fossil gastropods. The maximum level of the Little Valley lake was well below the Bonneville shoreline. Based on degree of soil development and other evidence, the Little Valley lake cycle may be equivalent in age to marine oxygenisotope stage 6. The proposed lake history has climatic implications for the region. First, because the fluctuations of Lake Bonneville and Lake Lahontan during the last cycle of each were apparently out of phase, there may have been significant local differences in the timing and character of late Pleistocene climate changes in the Great Basin. Second, although the Bonneville and Little Valley lake cycles were broadly synchronous with maximum episodes of glaciation, environmental conditions necessary to generate large lakes did not exist during early Wisconsin time. ?? 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)90013-3","issn":"00335894","usgsCitation":"Scott, W.E., McCoy, W., Shroba, R., and Rubin, M., 1983, Reinterpretation of the exposed record of the last two cycles of Lake Bonneville, Western United States: Quaternary Research, v. 20, no. 3, p. 261-285, https://doi.org/10.1016/0033-5894(83)90013-3.","startPage":"261","endPage":"285","numberOfPages":"25","costCenters":[],"links":[{"id":266559,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/0033-5894(83)90013-3"},{"id":220975,"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":"50e4a60ce4b0e8fec6cdc086","contributors":{"authors":[{"text":"Scott, W.
