Marl prairies are typified by dense, mixed stands of graminoid species usually below 1 m in height, naturally inundated by freshwater for 3–7 months annually. Water levels affect the birds directly, by flooding their nests, and indirectly by altering the habitat on which they depend. Managed redistribution of water flows flooded nearly half of the sparrow's geographical range during several consecutive breeding seasons starting in 1993. Furthermore, these high water levels rapidly changed plant communities, so jeopardizing the sparrow's survival by reducing the availability of nesting habitat.</span></p>","language":"English","publisher":"Zoological Society of London","doi":"10.1111/j.1469-1795.1998.tb00222.x","usgsCitation":"Nott, M.P., Bass, O.L., Fleming, D.M., Killeffer, S.E., Fraley, N., Manne, L., Curnutt, J.L., Brooks, T., Powell, R., and Pimm, S.L., 1998, Water levels, rapid vegetational changes, and the endangered Cape Sable seaside-sparrow: Animal Conservation, v. 1, no. 1, p. 23-32, https://doi.org/10.1111/j.1469-1795.1998.tb00222.x.","productDescription":"10 p.","startPage":"23","endPage":"32","numberOfPages":"10","costCenters":[],"links":[{"id":491487,"rank":2,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1111/j.1469-1795.1998.tb00222.x","text":"Publisher Index Page"},{"id":231074,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Florida","otherGeospatial":"Big Cypress National Preserve, Everglades National Park","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -81.3387659074362,\n              26.27575777292742\n            ],\n            [\n              -81.3387659074362,\n              25.053039022453717\n            ],\n            [\n              -80.44465322256413,\n              25.053039022453717\n            ],\n            [\n              -80.44465322256413,\n              26.27575777292742\n            ],\n            [\n              -81.3387659074362,\n              26.27575777292742\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","volume":"1","issue":"1","noUsgsAuthors":false,"publicationDate":"2006-02-28","publicationStatus":"PW","scienceBaseUri":"505bc852e4b08c986b32c8ab","contributors":{"authors":[{"text":"Nott, M.

Groundwater land-use studies, designed to sample recently recharged groundwater (generally within 10 years) beneath specific land-use and hydrogeologic settings, are a major component of the groundwater quality as sessment for NAWQA. Pesticide results from the 41 land-use studies conducted during 1993&minus;1995 indicate that pesticides were commonly detected in shallow groundwater, having been found at 54.4% of the 1034 sites sampled in agricultural and urban settings across the United States. Pesticide concentrations were generally low, with over 95% of the detections at concentrations less than 1 &mu;g/L. Of the 46 pesticide compounds examined, 39 were detected. The compounds detected most frequently were atrazine (38.2%), deethylatrazine (34.2%), simazine (18.0%), metolachlor (14.6%), and prometon (13.9%). Statistically significant relations were observed between frequencies of detection and the use, mobility, and persistence of these compounds. Pesticides were commonly detected in both agricultural (56.4%; 813 sites) and urban (46.6%; 221 sites) settings. Frequent detections of pesticides in urban areas indicate that, as is the case with agricultural pesticide use in agricultural areas, urban and suburban pesticide use significantly contribute to pesticide occurrence in shallow groundwater. Although pesticides were detected in groundwater sampled in urban areas and all nine of the agricultural land-use categories examined, significant variations in occurrence were observed among these categories. Maximum contaminant levels (MCLs) established by the U.S. Environmental Protection Agency for drinking water were exceeded for only one pesticide (atrazine, 3 &mu;g/L) at a single location. However, MCLs have been established for only 25 of the 46 pesticide compounds examined, do not cover pesticide degradates, and, at present, do not take into account additive or synergistic effects of combinations of pesticide compounds or potential effects on nearby aquatic ecosystems.</p>","language":"English","publisher":"American Chemical Society","publisherLocation":"Washington,

Flow rates at the deformation front for transient simulations are in good agreement with direct measurements, but steady state flow rates are 2–3 orders of magnitude smaller than observed.

The shear zone is characterized by a complicated composite fabric produced by the imposition of both ductile and brittle structures as well as the reactivation, transposition, and folding of older structures during subsequent antithetic displacement. At least five main types of structural elements are discernible and include: 1) relict, medium- to coarse-grained mylonitic foliation and related structures produced by sinistral shearing under at least middle amphibolite facies conditions; 2) a ductile fault zone having an apparent sinistral displacement of at least several km and an unknown, but possibly significant component of upward throw of the east wall; 3) pervasive, fine-grained ultramylonitic foliation associated with quartz ribbons and late oblique shear bands, generated by dextral shearing under thermal conditions that appear to have progressed from middle greenschist to sub-greenschist (semi-brittle); 4) a system of oblique-(west wall up) and dextralship faults localized chiefly within a tectonic me??lange at the junction of two major strands, and whose motion spanned the ductile-brittle transition; and 5) a system of post-Cretaceous thrust faults that cut Coastal Plain rocks as young as Quaternary as well as the previously deformed crystalline rocks. The first two sets of structures are of probable Ordovician age and are thus believed to coincide with the Taconic event, which produced regional middle to upper amphibolite facies metamorphism, widespread plutonism, and extensive southwest-vergent fold phases in this area. In contrast, the dextral shearing and faulting were generated during final thermal cooling and represent the latest Paleozoic penetrative deformation that affected this area. They are very likely Alleghanian because of their great similarity to other better-dated Alleghanian structural features in the Maryland and Virginia Piedmont.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Southeastern Geology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","issn":"00383678","usgsCitation":"Fleming, A., and Drake, A.A., 1998, Structure, age, and tectonic setting of a multiply reactivated shear zone in the piedmont in Washington, D.C., and vicinity: Southeastern Geology, v. 37, no. 3, p. 115-140.","startPage":"115","endPage":"140","numberOfPages":"26","costCenters":[],"links":[{"id":231501,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"37","issue":"3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505b9c67e4b08c986b31d3e8","contributors":{"authors":[{"text":"Fleming, A.H.","contributorId":43529,"corporation":false,"usgs":true,"family":"Fleming","given":"A.H.","email":"","affiliations":[],"preferred":false,"id":386973,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Drake, Avery A.

Based on data collected in 1951-1952, in Fillmore, Utah, we examined whether there had been a local decline in the dove population index since the original data were collected. We then determined whether habitat had been altered, identified which foraging habitats doves preferred, and assessed whether changes in land use could be responsible, in part, for a decline in the local population index. We found that dove population indices declined 72% and 82% from 1952-1992 and 1952-1993, respectively. The most dramatic change in habitat was an 82% decline in land devoted to dry land winter wheat production and a decline in livestock feed pens. Doves foraged primarily in harvested wheat fields, feed pens, and weedy patches. We hypothesize that a decrease in wheat availability during the spring and the consolidation of the livestock industry have contributed to a population decline of Mourning Doves in central Utah.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Field Ornithology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","issn":"02738570","usgsCitation":"Ostrand, W.D., Meyers, P., Bissonette, J., and Conover, M.R., 1998, Changes in land use as a possible factor in Mourning Dove population decline in Central Utah: Journal of Field Ornithology, v. 69, no. 2, p. 192-200.","startPage":"192","endPage":"200","numberOfPages":"9","costCenters":[],"links":[{"id":231500,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"69","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059f41ae4b0c8380cd4bb3b","contributors":{"authors":[{"text":"Ostrand, William D.","contributorId":90898,"corporation":false,"usgs":false,"family":"Ostrand","given":"William","email":"","middleInitial":"D.","affiliations":[{"id":609,"text":"Utah Cooperative Fish and Wildlife Research Unit","active":false,"usgs":true}],"preferred":false,"id":386972,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Meyers, P.M.","contributorId":80031,"corporation":false,"usgs":true,"family":"Meyers","given":"P.M.","email":"","affiliations":[],"preferred":false,"id":386971,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Bissonette, J.A.","contributorId":21498,"corporation":false,"usgs":true,"family":"Bissonette","given":"J.A.","email":"","affiliations":[],"preferred":false,"id":386970,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Conover, M.

At relatively low C(e)/S(w), both the nonpolar and the polar solutes exhibit nonlinear sorption. The sorption nonlinearity approaches apparent saturation at about C(e)/S(w) = 0.010-0.015 for the nonpolar solutes and at about C(e)/S(w) = 0.10-0.13 for the polar solutes; above these C(e)/S(w) regions, the isotherms are practically linear. The nonlinear sorption capacities are greater for polar solutes than for nonpolar solutes and the peat soil shows a greater effect than the Woodburn soil. The small nonlinear sorption capacity for a nonpolar solute is suppressed indiscriminately by either a nonpolar or a polar cosolute at relatively low C(e)/S(w) of the cosolute. By contrast, the abilities of different cosolutes to suppress the nonlinear capacity of a nominal polar solute differ drastically. For polar solutes, a nonpolar cosolute exhibits a limited suppression even at high cosolute C(e)/S(w); effective suppression occurs when the cosolute is relatively polar and at various C(e)/S(w). These differences suggest that more than a single mechanism is required to account for the nonlinear sorption of both nonpolar and polar compounds at low C(e)/S(w). Mechanistic processes consistent with these observations and with soil surface areas are discussed along with other suggested models. Some important consequences of the nonlinear competitive sorption to the behavior of contaminants in natural systems are discussed.A number of conceptual models was postulated to account for the nonlinear solute sorption on soils of significant soil organic matter. A series of single-solute and binary-route sorption data was obtained representing samples of polar compounds of substituted ureas and phenolic compounds, and of nonpolar compounds of EDB and trichloroethylene on a peat soil and a mineral on a Woodburn soil. The nonlinear sorption capacities are greater for polar solutes than for nonpolar solutes and the peat soil shows a greater effect than the Woodburn soil.","language":"English","publisher":"ACS","doi":"10.1021/es970608g","issn":"0013936X","usgsCitation":"Chiou, C.T., and Kile, D.E., 1998, Deviations from sorption linearity on soils of polar and nonpolar organic compounds at low relative concentrations: Environmental Science & Technology, v. 32, no. 3, p. 338-343, https://doi.org/10.1021/es970608g.","productDescription":"6 p.","startPage":"338","endPage":"343","costCenters":[{"id":589,"text":"Toxic Substances Hydrology Program","active":true,"usgs":true}],"links":[{"id":206970,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1021/es970608g"},{"id":231419,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"32","issue":"3","noUsgsAuthors":false,"publicationDate":"1998-02-01","publicationStatus":"PW","scienceBaseUri":"505a008ae4b0c8380cd4f7a9","contributors":{"authors":[{"text":"Chiou, C.

The word \"petrofacies\" makes an explicit link between petroleum engineers' concerns with pore characteristics as arbiters of production performance and the facies paradigm of geologists as a methodology for genetic understanding and prediction. In petrofacies analysis, the porosity and resistivity axes of the classical Pickett plot are used to map water saturation, bulk volume water, and estimated permeability, as well as capillary pressure information where it is available. When data points are connected in order of depth within a reservoir, the characteristic patterns reflect reservoir rock character and its interplay with the hydrocarbon column. A third variable can be presented at each point on the crossplot by assigning a color scale that is based on other well logs, often gamma ray or photoelectric effect, or other derived variables. Contrasts between reservoir pore types and fluid saturations are reflected in changing patterns on the crossplot and can help discriminate and characterize reservoir heterogeneity. Many hundreds of analyses of well logs facilitated by spreadsheet and object-oriented programming have provided the means to distinguish patterns typical of certain complex pore types (size and connectedness) for sandstones and carbonate reservoirs, occurrences of irreducible water saturation, and presence of transition zones. The result has been an improved means to evaluate potential production, such as bypassed pay behind pipe and in old exploration wells, or to assess zonation and continuity of the reservoir. Petrofacies analysis in this study was applied to distinguishing flow units and including discriminating pore type as an assessment of reservoir conformance and continuity. The analysis is facilitated through the use of colorimage cross sections depicting depositional sequences, natural gamma ray, porosity, and permeability. Also, cluster analysis was applied to discriminate petrophysically similar reservoir rock.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"AAPG Memoir","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","issn":"02718529","usgsCitation":"Watney, W., Guy, W.J., Doveton, J., Bhattacharya, S., Gerlach, P., Bohling, G.C., and Carr, T., 1998, Petrofacies Analysis - A Petrophysical Tool for Geologic/Engineering Reservoir Characterization: AAPG Memoir, no. 71, p. 73-90.","startPage":"73","endPage":"90","numberOfPages":"18","costCenters":[],"links":[{"id":228294,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"issue":"71","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a777de4b0c8380cd784e5","contributors":{"authors":[{"text":"Watney, W.L.","contributorId":43087,"corporation":false,"usgs":true,"family":"Watney","given":"W.L.","email":"","affiliations":[],"preferred":false,"id":384110,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Guy, W.

But if mantle peridotite is upwelling within the wedge, melting due to pressure release could also contribute to magma production. Here we present measurements of the volatile content of primitive magmas from Galunggung volcano in the Indonesian are which indicate that these magmas were derived from the pressure-release melting of hot mantle peridotite. The samples that we have analysed consist of mafic glass inclusions in high-magnesium basalts. The inclusions contain uniformly low H2O concentrations (0.21-0.38 wt%), yet relatively high levels of CO2 (up to 750 p.p.m.) indicating that the low H2O concentrations are primary and not due to degassing of the magma. Results from previous anhydrous melting experiments on a chemically similar Aleutian basalts indicate that the Galunggung high-magnesium basalts were last in equilibrium with peridotite at ~1,320 ??C and 1.2 GPa. These high temperatures at shallow sub-crustal levels (about 300-600 ??C hotter than predicted by geodynamic models), combined with the production of nearly H2O- free basaltic melts, provide strong evidence that pressure-release melting due to upwelling in the sub-are mantle has taken place. Regional low- potassium and low-H2O (ref. 5) basalts found in the Cascade are indicate that such upwelling-induced melting can be widespread.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Nature","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1038/36087","issn":"00280836","usgsCitation":"Sisson, T.W., and Bronto, S., 1998, Evidence for pressure-release melting beneath magmatic arcs from basalt at Galunggung, Indonesia: Nature, v. 391, no. 6670, p. 883-886, https://doi.org/10.1038/36087.","startPage":"883","endPage":"886","numberOfPages":"4","costCenters":[],"links":[{"id":206962,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1038/36087"},{"id":231381,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"391","issue":"6670","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a0d4ee4b0c8380cd52f36","contributors":{"authors":[{"text":"Sisson, T.

In order to understand these discrepancies better, we investigated the lake-level history of 40-km-long Moosehead Lake in northwestern Maine. Glacioisostasy has affected the level of Moosehead Lake since deglaciation ca. 12,500 14C yr B.P. Lowstand features at the southeastern end and an abandoned outlet at the northwestern end of the lake indicate that the lake basin was tilted down to the northwest, toward the retreating ice sheet, by 0.7 m/km at 10,000 14C yr B.P. Water level then rose rapidly in the southeastern end of the lake, and the northwestern outlet was abandoned, indicating rapid relaxation of landscape tilt. Lowstand features at the northwestern end of the lake suggest that the lake basin was tilted to the southeast at ca. 8750 14C yr B.P., possibly as the result of a migrating isostatic forebulge. After 8000 14C yr B.P., water level at the southeastern end was again below present lake level and rose gradually thereafter. We found no evidence suggesting that postglacial climate change significantly affected lake level. The rebound history inferred from lake-level data is consistent with previous interpretations of nearby relative sealevel data, which indicate a significantly steeper and faster-moving ice-proximal depression and ice-distal forebulge than geophysical models predict. ?? 1998 University of Washington.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Quaternary Research","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Elsevier","publisherLocation":"Amsterdam, Netherlands","doi":"10.1006/qres.1998.1962","issn":"00335894","usgsCitation":"Balco, G., Belknap, D.F., and Kelley, J.T., 1998, Glacioisostasy and Lake-Level Change at Moosehead Lake, Maine: Quaternary Research, v. 49, no. 2, p. 157-170, https://doi.org/10.1006/qres.1998.1962.","startPage":"157","endPage":"170","numberOfPages":"14","costCenters":[],"links":[{"id":231270,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":266453,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1006/qres.1998.1962"}],"volume":"49","issue":"2","noUsgsAuthors":false,"publicationDate":"2017-01-20","publicationStatus":"PW","scienceBaseUri":"505a2926e4b0c8380cd5a6ed","contributors":{"authors":[{"text":"Balco, G.","contributorId":44317,"corporation":false,"usgs":true,"family":"Balco","given":"G.","affiliations":[],"preferred":false,"id":386927,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Belknap, D.

The building is modeled as a layered medium, similar to a layered soil medium, and is subjected to vertically propagating seismic shear waves. Soil layers and the bedrock under the foundation are incorporated in the formulation as additional layers. Seismic response is expressed in terms of the wave travel times between the layers, and the wave reflection and transmission coefficients at the layer interfaces. The equations account for the frequency-dependent filtering effects of the foundation and floor masses. The calculation of seismic response is reduced to a pair of simple finite-difference equations for each layer, which can be solved recursively starting from the bedrock. Compared to the commonly used vibration formulation, the wave propagation formulation provides several advantages, including simplified calculations, better representation of damping, ability to account for the effects of the soil layers under the foundation, and better tools for identification and damage detection from seismic records.

Five third-order (1-10 my) and fourth-order (0.1-1.0 my) upper Miocene carbonate depositional sequences (DS1A, DS1B, DS2, DS3, TCC) formed with superimposed higher-frequency sea-level cycles in an archipelago setting in SE Spain. Overall, our study indicates when areas of high substrate slope (&gt;15 degrees ) are in shallow water, independent of climate, the location and internal architecture of carbonate deposits are not directly linked to sea-level position but, instead, are controlled by location of gently sloping substrates and processes of bypass. In contrast, if carbonate sediments are generated where substrates of low slope (&lt;15 degrees in our area) are in shallow water, then architecture and location of deposits may be more directly controlled by the relative position of sea level. For these systems, the rates of relative sea-level change are important for determining which systems tracts develop. DS1A-DS1B, cooler-water ramps, result from sediment bypass across steep paleoslopes to toes of slopes. Accumulation rates decreased from &gt;15.6 cm/ky to approximately 2 cm/ky and overall relative sea level rose at rates of 17-21.4 cm/ky. Higher frequency sea-level rates were about 111 to more than 260 cm/ky, producing onlapping, fining- (deepening-) upward cycles. Decreasing accumulation rates resulted from decreasing surface area for shallow-water sediment production, drowning of shallow-water substrates, and complex sediment dispersal related to the archipelago setting. Typical systems tract and parasequence development should not be expected in \"bypass ramp\" settings; facies of onlapping strata do not track base level and are likely to be significantly different compared to onlapping strata associated with coastal onlap. Basal and upper DS2 reef megabreccias (indicating the transition from cool to warmer climatic conditions) were eroded from steep upslope positions and redeposited downslope onto areas of gentle substrate during rapid sea-level falls (&gt;22.7 cm/ky) of short duration. Such rapid sea-level falls and presence of steep slopes are not conducive to formation of forced regressive systems tracts composed of down-stepping reef clinoforms. The DS3 reefal platform formed where shallow water coincided with gently sloping substrates created by earlier deposition. Slow progradation (0.39-1.45 km/my) is best explained by the lack of an extensive bank top, progressively falling sea level, and low productivity resulting from siliciclastic debris and excess nutrients shed from nearby volcanic islands. Although DS3 strata were deposited during a third-order relative sea-level cycle, a typical transgressive systems tract is not recognizable, indicating that the initial relative rise in sea level was too rapid (&gt;&gt;19 cm/ky). Downstepping reefs, forming a forced regressive systems tract, were deposited during the relative sea-level fall at the end of DS3, indicating that relatively slow rates of fall (10 cm/ky or less) over favorable paleoslope conditions are conducive to generation of forced regressive systems tracts consisting of downstepping reef clinoforms. The TCC sequence consists of four shallow-water sedimentary cycles that were deposited during a 400 ky to 100 ky time span. Such shallow-water cycles, typical of many platforms, form only where shallow water intersects gently sloping substrates. The relative thicknesses of cycles (&lt;2 m to 15 m thick), magnitudes of relative sea-level fluctuations associated with each cycle (25-30 m), high rates of relative sea-level fluctuations (minimum of 25-120 cm/ky), and the widespread distribution of similar TCC cycles in the Mediterranean and elsewhere are supportive of a glacio-eustatic influence. With rates of sea-level change so high, typical systems tracts do not form.</p></div></div>","language":"English","publisher":"Society for Sedimentary Geology","doi":"10.2110/jsr.68.283","issn":"15271404","usgsCitation":"Franseen, E.K., Goldstein, R., and Farr, M., 1998, Quantitative controls on location and architecture of carbonate depositional sequences: upper miocene, cabo de gata region, se Spain: Journal of Sedimentary Research, v. 68, no. 2, p. 283-298, https://doi.org/10.2110/jsr.68.283.","productDescription":"16 p.","startPage":"283","endPage":"298","numberOfPages":"16","costCenters":[],"links":[{"id":228102,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"68","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a9211e4b0c8380cd80624","contributors":{"authors":[{"text":"Franseen, E.

The well was drilled to evaluate the hydraulic properties of the Cretaceous formations beneath Hilton Head Island as a potential source of supplemental water to supplies currently withdrawn from the Upper Floridan aquifer. The intervals tested include sediments of the Cape Fear and Middendorf Formations. Results from aquifer tests indicate that the transmissivity of the formations screened ranges from 1300 to 3000 feet squared per day and an average hydraulic conductivity of about 15 feet per day. Formation-fluid pressure tests indicate that the potential exists for upward ground-water flow from higher fluid pressures in the deeper Cape Fear and Middendorf Formations to lower fluid pressures in the Black Creek Formation and shallower units. A flowmeter test indicated that greater than 75 percent of the natural, unpumped flow in the well is from the screened intervals no deeper than 3100 feet. Water-chemistry analyses indicate that the water sampled from the Middendorf and Cape Fear has about 1450 milligrams per liter dissolved solids, 310 to 1000 milligrams per liter sodium, and 144 to 1600 milligrams per liter chloride. Because these chloride concentrations would render water pumped from these aquifers as nonpotable, it is unlikely that these aquifers will be used as a supplemental source of water for island residents without some form of pretreatment. Similar chloride concentrations are present in some wells in the Upper Floridan aquifer adjacent to Port Royal Sound, and these chloride concentrations were the primary reason for drilling the test well in the Cretaceous formations as a possible source of more potable water.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Southeastern Geology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","issn":"00383678","usgsCitation":"Landmeyer, J., and Bradley, P., 1998, Hydrologic and water-chemistry data from the Cretaceous-aquifers test well (BFT-2055), Beaufort County, South Carolina: Southeastern Geology, v. 37, no. 3, p. 141-148.","startPage":"141","endPage":"148","numberOfPages":"8","costCenters":[{"id":13634,"text":"South Atlantic Water Science Center","active":true,"usgs":true}],"links":[{"id":231108,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"South Carolina","county":"Beaufort County","volume":"37","issue":"3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a355de4b0c8380cd5fe61","contributors":{"authors":[{"text":"Landmeyer, J.

Controversy has developed over whether invading or encroaching pinon and juniper species are inherently harmful to rangeland ecosystems. We developed a conceptual model of soil erosion in pinon-jumper ecosystems that is consistent with both sides of the controversy and suggests that the diverse perspectives on this issue arise from threshold effects operating under very different site conditions. Soil erosion rate can be viewed as a function of (1) site erosion potential (SEP), determined by climate, geomorphology and soil erodibility; and (2) ground cover. Site erosion potential and cove act synergistically to determine soil erosion rates, as evident even from simple USLE predictions of erosion. In pinon-juniper ecosystem with high SEP, the erosion rate is highly sensitive to ground cover and can cross a threshold so that erosion increases dramatically in response to a small decrease in cover. The sensitivity of erosion rate to SEP and cover can be visualized as a cusp catastrophe surface on which changes may occur rapidly and irreversibly. The mechanisms associated with a rapid shift from low to high erosion rate can be illustrated using percolation theory to incorporate spatial, temporal, and scale-dependent patterns of water storage capacity on a hillslope. Percolation theory demonstrates how hillslope runoff can undergo a threshold response to a minor change in storage capacity. Our conceptual model suggests that pinion and juniper contribute to accelerated erosion only under a limited range of site conditions which, however, may exist over large areas.</p>","language":"English","publisher":"Society for Range Management","doi":"10.2307/4003212","usgsCitation":"Davenport, D.W., Breshears, D., Wilcox, B., and Allen, C.D., 1998, Viewpoint: Sustainability of piñon-juniper ecosystems - A unifying perspective of soil erosion thresholds: Journal of Range Management, v. 51, no. 2, p. 231-240, https://doi.org/10.2307/4003212.","productDescription":"10 p.","startPage":"231","endPage":"240","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[{"id":291,"text":"Fort Collins Science Center","active":true,"usgs":true}],"links":[{"id":479857,"rank":1,"type":{"id":41,"text":"Open Access External Repository Page"},"url":"http://hdl.handle.net/10150/644200","text":"External Repository"},{"id":231070,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"51","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505bc260e4b08c986b32aae0","contributors":{"authors":[{"text":"Davenport, David W.","contributorId":18135,"corporation":false,"usgs":false,"family":"Davenport","given":"David","email":"","middleInitial":"W.","affiliations":[],"preferred":false,"id":386870,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Breshears, D.D.","contributorId":17952,"corporation":false,"usgs":false,"family":"Breshears","given":"D.D.","email":"","affiliations":[{"id":12625,"text":"School of Natural Resources and the Environment, University of Arizona, Tucson, AZ, 85721, USA","active":true,"usgs":false}],"preferred":false,"id":386869,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Wilcox, B.P.","contributorId":83490,"corporation":false,"usgs":true,"family":"Wilcox","given":"B.P.","email":"","affiliations":[],"preferred":false,"id":386872,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Allen, Craig D. 0000-0002-8777-5989 craig_allen@usgs.gov","orcid":"https://orcid.org/0000-0002-8777-5989","contributorId":2597,"corporation":false,"usgs":true,"family":"Allen","given":"Craig","email":"craig_allen@usgs.gov","middleInitial":"D.","affiliations":[{"id":290,"text":"Forest and Rangeland Ecosystem Science Center","active":false,"usgs":true},{"id":291,"text":"Fort Collins Science Center","active":true,"usgs":true}],"preferred":true,"id":386871,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

Therefore, a bias in the characterization of habitat surrounding northern goshawk nest sites may exist toward late-forest structure (large trees, high canopy closure). This potential problem has confounded interpretation of data on nesting habitat of northern goshawks and added to uncertainty in the review process to consider the species for federal listing as threatened or endangered. Systematic survey methods, which strive for complete coverage of an area and often use broadcasts of conspecific calls, have been developed to overcome these potential biases, but no study has compared habitat characteristics around nests found opportunistically with those found systematically. We compared habitat characteristics in a 0.4-ha area around nests found systematically (n = 27) versus those found opportunistically (n = 22) on 3 national forests in eastern Oregon. We found that both density of large trees (systematic: x?? = 16.4 ?? 3.1 trees/ha; x?? ?? SE; opportunistic: x?? = 21.3 ?? 3.2; P = 0.56) and canopy closure (systematic: x?? = 72 ?? 2%; opportunistic: x?? = 70 ?? 2%; P = 0.61) were similar around nests found with either search method. Our results diminish concern that past survey methods mischaracterized northern goshawk nest-site structure. However, because northern goshawks nest in a variety of forest cover types with a wide range of structural characteristics, these results do not decrease the value of systematic survey methods in determining the most representative habitat descriptions for northern goshawks. Rigorous survey protocols allow repeatability and comparability of monitoring efforts and results over time.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Wildlife Management","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","issn":"0022541X","usgsCitation":"Daw, S., DeStefano, S., and Steidl, R., 1998, Does survey method bias the description of northern goshawk nest-site structure?: Journal of Wildlife Management, v. 62, no. 4, p. 1379-1384.","startPage":"1379","endPage":"1384","numberOfPages":"6","costCenters":[],"links":[{"id":231033,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"62","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a0398e4b0c8380cd5056b","contributors":{"authors":[{"text":"Daw, S.K.","contributorId":20501,"corporation":false,"usgs":true,"family":"Daw","given":"S.K.","email":"","affiliations":[],"preferred":false,"id":386867,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"DeStefano, S.","contributorId":84309,"corporation":false,"usgs":true,"family":"DeStefano","given":"S.","email":"","affiliations":[],"preferred":false,"id":386868,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Steidl, R.J.","contributorId":16383,"corporation":false,"usgs":true,"family":"Steidl","given":"R.J.","email":"","affiliations":[],"preferred":false,"id":386866,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

On one side are those who believe we are rapidly depleting resources and that the resulting shortages will have a profound impact on society. On the other side are those who see no impending crisis because long-term trends are for cheaper prices despite rising production. The concepts of resources and reserves have historically created considerable misunderstanding in the minds of many nongeologists. Hubbert-type predictions of energy production assume that there is a finite supply of energy that is measurable; however, estimates of resources and reserves are inventories of the amounts of a fossil fuel perceived to be available over some future period of time. As those resources/reserves are depleted over time, additional amounts of fossil fuels are inventoried. Throughout most of this century, for example, crude oil reserves in the United States have represented a 10-14-yr supply. For the last 50 yr, resource crude oil estimates have represented about a 60-70-yr supply for the United States. Division of reserve or resource estimates by current or projected annual consumption therefore is circular in reasoning and can lead to highly erroneous conclusions. Production histories of fossil fuels are driven more by demand than by the geologic abundance of the resource. Examination of some energy resources with well-documented histories leads to two conceptual models that relate production to price. The closed-market model assumes that there is only one source of energy available. Although the price initially may fall because of economies of scale long term, prices rise as the energy source is depleted and it becomes progressively more expensive to extract. By contrast, the open-market model assumes that there is a variety of available energy sources and that competition among them leads to long-term stable or falling prices. At the moment, the United States and the world approximate the open-market model, but in the long run the supply of fossil fuel is finite, and prices inevitably will rise unless alternate energy sources substitute for fossil energy supplies; however, there appears little reason to suspect that long-term price trends will rise significantly over the next few decades.Over the last 25 years, considerable debate has continued about the future supply of fossil fuel. On one side are those who believe that resources are rapidly depleting and that the resulting shortages will have a profound impact on society.

Such an approach provides a recycling path for waste tires and the production of new adsorbents from a low-cost waste material. Tire-derived activated carbons (TDACs) were prepared from waste tires. The resulting products are generally mesoporous, with N2-BET specific surface areas ranging from 239 to 1031 m2/g. TDACs were tested for their ability to store natural gas and remove organic compounds and mercury species from gas streams. TDACs are able to achieve 36% of the recommended adsorbed natural gas (methane) storage capacity for natural-gas-fueled vehicles. Equilibrium adsorption capacities for CH4 achieved by TDACs are comparable to Calgon BPL, a commercially available activated-carbon adsorbent. The acetone adsorption capacity for a TDAC is 67% of the adsorption capacity achieved by BPL at 1 vol % acetone. Adsorption capacities of mercury in simulated flue-gas streams are, in general, larger than adsorption capacities achieved by coal-derived activated carbons (CDACs) and BPL. Although TDACs may not perform as well as commercial adsorbents in some air pollution control applications, the potential lower cost of TDACS should be considered when evaluating economics.","language":"English","publisher":"American Chemical Society","doi":"10.1021/ef9801120","issn":"08870624","usgsCitation":"Lehmann, C., Rostam-Abadi, M., Rood, M., and Sun, J., 1998, Reprocessing and reuse of waste tire rubber to solve air-quality related problems: Energy and Fuels, v. 12, no. 6, p. 1095-1099, https://doi.org/10.1021/ef9801120.","productDescription":"5 p.","startPage":"1095","endPage":"1099","numberOfPages":"5","costCenters":[],"links":[{"id":231458,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"12","issue":"6","noUsgsAuthors":false,"publicationDate":"1998-10-09","publicationStatus":"PW","scienceBaseUri":"505aa885e4b0c8380cd8595d","contributors":{"authors":[{"text":"Lehmann, C.M.B.","contributorId":96862,"corporation":false,"usgs":true,"family":"Lehmann","given":"C.M.B.","email":"","affiliations":[],"preferred":false,"id":386832,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Rostam-Abadi, M.","contributorId":37061,"corporation":false,"usgs":true,"family":"Rostam-Abadi","given":"M.","affiliations":[],"preferred":false,"id":386831,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Rood, M.J.","contributorId":15354,"corporation":false,"usgs":true,"family":"Rood","given":"M.J.","email":"","affiliations":[],"preferred":false,"id":386829,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Sun, Jielun","contributorId":33443,"corporation":false,"usgs":true,"family":"Sun","given":"Jielun","email":"","affiliations":[],"preferred":false,"id":386830,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

Because of this tectonic setting, there are three distinct earthquake source zones in earthquake hazard assessments of the Seattle area. Offshore, the broad sloping interface between the Juan de Fuca and the North America plates produces earthquakes as large as magnitude 9; on the average these events occur every 400-600 years. The second source zone is within the subducting Juan de Fuca plate as it bends, at depths of 40-60 km, beneath the Puget lowland. Five earthquakes in this zone this century have had magnitudes greater than 6, including one magnitude 7.1 event in 1949. The third zone, the crust of the North America plate, is the least well known. Paleoseismic evidence shows that an event of approximate magnitude 7 occurred on the Seattle fault about 1000 years ago. Potentially very damaging to the heavily urbanized areas of Puget Sound, the rate of occurrence and area over which large magnitude crustal events are to be expected is the subject of considerable research.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Geotechnical Special Publication","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","issn":"08950563","usgsCitation":"Weaver, C., 1998, No longer so clueless in seattle: Current assessment of earthquake hazards: Geotechnical Special Publication, no. 75 I, p. 39-52.","startPage":"39","endPage":"52","numberOfPages":"14","costCenters":[],"links":[{"id":231417,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"issue":"75 I","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a670ee4b0c8380cd73152","contributors":{"authors":[{"text":"Weaver, C.S.","contributorId":57874,"corporation":false,"usgs":true,"family":"Weaver","given":"C.S.","email":"","affiliations":[],"preferred":false,"id":386828,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

The Mahalanobis distance statistic was used to represent the standard squared distance between sample variates in the GIS database (forest cover type, elevation, slope, aspect, distance to streams, distance to roads, and forest cover richness) and variates at known bear dens. Two models were developed: a generalized model for all den locations and another specific to dens in rock cavities. Differences between habitat at den sites and habitat across the study area were represented in 2 new GIS themes as Mahalanobis distance values. Cells similar to the mean vector derived from the known dens had low Mahalanobis distance values, and dissimilar cells had high values. The reliability of the predictive model was tested by overlaying den locations collected subsequent to original model development on the resultant den habitat themes. Although the generalized model demonstrated poor reliability, the model specific to rock dens had good reliability. Bears were more likely to choose rock den locations with low Mahalanobis distance values and less likely to choose those with high values. The model can be used to plan the timing and extent of management actions (e.g., road building, prescribed fire, timber harvest) most appropriate for those sites with high or low denning potential.&nbsp;</p>","language":"English","publisher":"International Association for Bear Research and Management","usgsCitation":"Clark, J.D., Hayes, S., and Pledger, J., 1998, A female black bear denning habitat model using a geographic information system: Ursus, v. 10, p. 181-185.","productDescription":"5 p.","startPage":"181","endPage":"185","numberOfPages":"5","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[{"id":365,"text":"Leetown Science Center","active":true,"usgs":true},{"id":481,"text":"Northern Rocky Mountain Science Center","active":true,"usgs":true}],"links":[{"id":129344,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Arkansas","otherGeospatial":"Dry Creek Wilderness Area, Ouachita Mountain region","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -93.8067626953125,\n              35.092945313732635\n            ],\n            [\n              -93.74633789062499,\n              35.088450570365396\n            ],\n            [\n              -93.680419921875,\n              35.088450570365396\n            ],\n            [\n              -93.61175537109375,\n              35.088450570365396\n            ],\n            [\n              -93.49227905273438,\n              35.099686964274724\n            ],\n            [\n              -93.48129272460936,\n              35.080584173400815\n            ],\n            [\n              -93.4771728515625,\n              35.023248960913385\n            ],\n            [\n              -93.48129272460936,\n              34.93885938523973\n            ],\n            [\n              -93.52935791015625,\n              34.918592949176926\n            ],\n            [\n              -93.61175537109375,\n              34.88367790965999\n            ],\n            [\n              -93.76144409179688,\n              34.84987503195418\n            ],\n            [\n              -93.84246826171875,\n              34.81154831029378\n            ],\n            [\n              -93.9276123046875,\n              34.78899484825181\n            ],\n            [\n              -94.0869140625,\n              34.785611296793306\n            ],\n            [\n              -94.26544189453125,\n              34.8025276659169\n            ],\n            [\n              -94.28741455078125,\n              34.83522280367885\n            ],\n            [\n              -94.31350708007812,\n              34.88818391007525\n            ],\n            [\n              -94.31076049804688,\n              34.942236637841184\n            ],\n            [\n              -94.31076049804688,\n              34.98275281869196\n            ],\n            [\n              -94.295654296875,\n              35.02662273458687\n            ],\n            [\n              -94.22836303710938,\n              35.064849103829204\n            ],\n            [\n              -94.12399291992188,\n              35.08957427943165\n            ],\n            [\n              -93.99627685546874,\n              35.1041810882765\n            ],\n            [\n              -93.91937255859375,\n              35.113168592954004\n            ],\n            [\n              -93.8067626953125,\n              35.092945313732635\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"10","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b24e4b07f02db6aecb0","contributors":{"authors":[{"text":"Clark, J.
