This report includes a synopsis of the theory and calculations associated with Gran's technique and presents a simple and inexpensive method for performing alkalinity and acidity determinations. However, potential sources of error introduced by the chemical character of some waters may limit the utility of Gran's technique. Therefore, the cost- and time-efficient method for performing alkalinity and acidity determinations described in this report is useful for exploring the suitability of Gran's technique in studies of water chemistry.","language":"ENGLISH","publisher":"U.S. Geological Survey ;\r\nEarth Science Information Center, Open-File Reports Section,","doi":"10.3133/wri894029","usgsCitation":"Barringer, J.L., and Johnsson, P., 1996, Theoretical considerations and a simple method for measuring alkalinity and acidity in low-pH waters by gran titration: U.S. Geological Survey Water-Resources Investigations Report 89-4029, iv, 36 p. :ill. ;28 cm., https://doi.org/10.3133/wri894029.","productDescription":"iv, 36 p. :ill. ;28 cm.","costCenters":[],"links":[{"id":157851,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/wri/1989/4029/report-thumb.jpg"},{"id":54849,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/wri/1989/4029/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a58e4b07f02db62e99d","contributors":{"authors":[{"text":"Barringer, J.

Although there have been several laboratory studies and some field experiments, quantitative information on the performance of ADCP's under field conditions is relatively rare but essential to proper assessment of the potential uses and limitations of these instruments. This study was a comparative evaluation of river discharge data and ADCP data collected with conventional methods at 12 selected U.S. Geological Survey streamflow- gaging stations in the continental United States.</p>\n<p>ADCP discharge measurements were made at the 12 sites in 1994. Twenty-six of the 31 measurements differed by less than 5 percent from the discharges determined with conventional methods. All 31 ADCP measurements were within 8 percent of the conventional method discharges.</p>\n<p>The standard deviations of the ADCP measurements ranged from approximately 1 to 6 percent and were generally higher than the measurement errors predicted by error-propagation analysis of ADCP instrument performance. These error-prediction methods assume that the largest component of ADCP discharge measurement error is instrument related. The larger standard deviations indicate that substantial portions of measurement error may be attributable to sources unrelated to ADCP electronics or signal processing and are functions of the field environment.</p>","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Indianapolis, IN","doi":"10.3133/wri954218","usgsCitation":"Morlock, S.E., 1996, Evaluation of Acoustic

We have developed a technique to enhance these \"pseudo-sidescan\" images in order to mimic the neighbouring GLORIA backscatter intensities. As a result, the enhanced images greatly facilitate the geologic interpretation of the adjacent GLORIA data, and geologic features evident in the GLORIA data may be correlated with greater confidence across track. Features interpreted from the pseudo-sidescan may be extrapolated from the near-nadir region out into the GLORIA range where they may not have been recognized otherwise, and therefore the pseudo-sidescan can be used to ground-truth GLORIA interpretations. Creation of digital sidescan mosaics utilized an approach not previously used for GLORIA data. Pixels were correctly placed in cartographic space and the time required to complete a final mosaic was significantly reduced. Computer software for digital mapping and mosaic creation is incorporated into the newly-developed Woods Hole Image Processing System (WHIPS) which can process both low- and high-frequency sidescan, and can interchange data with the Mini Image Processing System (MIPS) most commonly used for GLORIA processing. These techniques are tested by creating digital mosaics of merged GLORIA sidescan and Hydrosweep pseudo-sidescan data from the vicinity of the Juan Fernandez microplate along the East Pacific Rise (EPR).&nbsp;</p>","language":"English","publisher":"Springer Nature","doi":"10.1007/BF00313879","issn":"00253235","usgsCitation":"Bird, R., Searle, R.C., Paskevich, V., and Twichell, D., 1996, Merged GLORIA sidescan and hydrosweep pseudo-sidescan: Processing and creation of digital mosaics: Marine Geophysical Research, v. 18, no. 6, p. 651-661, https://doi.org/10.1007/BF00313879.","productDescription":"11 p.","startPage":"651","endPage":"661","costCenters":[{"id":678,"text":"Woods Hole Coastal and Marine Science Center","active":true,"usgs":true}],"links":[{"id":227178,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"18","issue":"6","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a5438e4b0c8380cd6cf01","contributors":{"authors":[{"text":"Bird, R.T.","contributorId":97263,"corporation":false,"usgs":true,"family":"Bird","given":"R.T.","email":"","affiliations":[],"preferred":false,"id":380522,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Searle, R.

Concentrations of 28 organochlorine compounds in composited whole fish samples were measured at 32 sites, and concentrations of 22 trace elements in composited fish liver samples were measured at 14 of the 32 sites. Most frequently detected organochlorines were DDT related compounds at 31 sites, total PCBs at 28 sites, and chlordane related compounds at 25 sites. Concentrations of total PCBs in fish tissue were generally higher at the large river sites than at the smaller tributary sites. Concentrations of chlordane-related compounds in fish tissue were higher at sites from more urbanized basins than at sites from predominately agriculture and forested basins. Concentrations of the DDT related compounds were undifferentiated among sites comprising different land uses. Trace elements detected at all 14 sites included boron, copper, iron, manganese, molybdenum, selenium, and zinc. Trace elements detected at 10 or more sites included arsenic, mercury, silver, strontium, and vanadium.

The routes use part of a Copper River and Northwest Railway alignment along the Copper River through mountainous terrain having numerous glaciers. An advance of any of several glaciers could block and destroy the roadway, whereas retreating glaciers expose large quantities of unconsolidated, unvegetated, and commonly ice-rich sediments. The purpose of this study was to map historical locations of glacier termini near these routes and to describe hazards associated with glaciers and seasonal snow. Historical and recent locations of glacier termini along the proposed Copper River Highway routes were determined by reviewing reports and maps and by interpreting aerial photographs. The termini of Childs, Grinnell, Tasnuna, and Woodworth Glaciers were 1 mile or less from a proposed route in the most recently available aerial photography (1978-91); the termini of Allen, Heney, and Schwan Glaciers were 1.5 miles or less from a proposed route. In general, since 1911, most glaciers have slowly retreated, but many glaciers have had occasional advances. Deserted Glacier and one of its tributary glaciers have surge-type medial moraines, indicating potential rapid advances. The terminus of Deserted Glacier was about 2.1 miles from a proposed route in 1978, but showed no evidence of surging. Snow and rock avalanches and snowdrifts are common along the proposed routes and will periodically obstruct the roadway. Floods from ice-dammed lakes also pose a threat. For example, Van Cleve Lake, adjacent to Miles Glacier, is as large as 4.4 square miles and empties about every 6 years. Floods from drainages of Van Cleve Lake have caused the Copper River to rise on the order of 20 feet at Million Dollar Bridge.","language":"ENGLISH","publisher":"U.S. Geological Survey ;\r\nBranch of Information Services [distributor],","doi":"10.3133/wri964074","usgsCitation":"Glass, R.L., 1996, Glaciers along proposed routes extending the Copper River Highway, Alaska: U.S. Geological Survey Water-Resources Investigations Report 96-4074, v, 39 p. :ill., maps ;28 cm., https://doi.org/10.3133/wri964074.","productDescription":"v, 39 p. :ill., maps ;28 cm.","costCenters":[],"links":[{"id":124052,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/wri/1996/4074/report-thumb.jpg"},{"id":56192,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/wri/1996/4074/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4ac5e4b07f02db679d06","contributors":{"authors":[{"text":"Glass, R.

Surface water, ground water, and irrigation water were sampled at three pairs of golf courses quarterly for one year to determine if pesticides were present, and the effect of irrigation with treated effluent on ground-water quality, with an emphasis on interactions of effluent with pesticides. In addition to the six paired golf courses, which were in central Florida, ground water was sampled for pesticides and other constituents at three more golf courses in other parts of the State. This study was the first to analyze water samples from Florida golf courses for a broad range of pesticides. Statistical methods based on the percentage of data above detection limits were used to determine the effects of irrigation with reclaimed water on ground-water quality. Shallow ground water at golf courses irrigated with treated effluent has higher concentrations of chloride, lower concentrations of bicarbonate, and lower pH than ground water at golf courses irrigated with water from carbonate aquifers. There were no statistically significant differences in nutrient concentrations in ground water between paired golf courses grouped by irrigation water type at a 95 percent confidence level. The number of wells where pesticides occurred was significantly higher at the paired golf courses using ground water for irrigation than at ones using reclaimed water. However, the limited occurrences of individual pesticides in ground water make it difficult to correlate differences in irrigation- water quality with pesticide migration to the water table. At some of the golf courses, increased pesticide occurrences may be associated with higher irrigation rates, the presence of well-drained soils, and shallow depths to the surficial aquifer. Pesticides used by golf courses for turf grass maintenance were detected in ground water on seven of nine golf courses studied and in 52 percent of ground-water samples. Concentrations of pesticides in ground water at golf courses were generally low relative to gegulatory guidelines, with 45 percent of all occurrences at trace levels and 92 percent under the maximum contaminant level or guidance concentration. Two of the nine golf courses had not pesticides detectedc in ground water, and a third had only two occurrences, which were at trace levels. Theere were six occurrences of concentrations of arsenic, bentazon, or acephate in ground water above the maximum contaminant level or guidance concentration. Additionally, the following pesticides were detected in ground water from at least one site; atrazine, bromacil, diazinon, diuron, fenamiphos, metalaxyl, oxydiazon, and simazine. The fenamiphos metabolites, fenamiphos sulfoxide and fenamiphos sulfone, also were detected in ground water. Samples from wastewater treatment plants contained trace levels of atrazine, bromacil, and gamma-BHC (Lindane). Concentrations of pesticides in golf course ponds  were generally low, with 60 percent of all occurrences at trace levels. All but one of the pond samples collected during the study contained at least one pesticide. The most commonly occurring pesticides in golf course ponds were: atrazine, fenamiphos and fenamiphos sulfoxide, and diuron.","language":"ENGLISH","publisher":"U.S. Geological Survey ;\r\nOpen-File Reports Section [distributor],","doi":"10.3133/wri954250","usgsCitation":"Swancar, A., 1996, Water quality, pesticide occurrence, and effects of irrigation with reclaimed water at golf courses in Florida: U.S. Geological Survey Water-Resources Investigations Report 95-4250, iv, 86 p. :ill., maps ;28 cm., https://doi.org/10.3133/wri954250.","productDescription":"iv, 86 p. :ill., maps ;28 cm.","costCenters":[],"links":[{"id":2476,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.water.usgs.gov/wri954250","linkFileType":{"id":5,"text":"html"}},{"id":159286,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e48cfe4b07f02db545d58","contributors":{"authors":[{"text":"Swancar, Amy aswancar@usgs.gov","contributorId":450,"corporation":false,"usgs":true,"family":"Swancar","given":"Amy","email":"aswancar@usgs.gov","affiliations":[{"id":595,"text":"U.S. Geological Survey","active":false,"usgs":true}],"preferred":false,"id":202583,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

It occupies ~4000 km2 across 11 mountain ranges in southern Nevada, has an average thickness of ~70 m, and contains a volume of 250+ km3. The breccia is a single bed, of early Frasnian (early Late Devonian) age, that formed in the wake of a giant slide that deposited a lower chaotic debrite, containing clasts as large as 80 × 500 m, and an upper exquisitely graded turbidite. It is anomalously intercalated with cyclic shallow-water platform carbonates of the Guilmette Formation. The Alamo breccia is interpreted as a product of the Alamo event, a nearby marine impact of an extraterrestrial object, whereby impact-generated crustal shock waves and/or marine superwaves detached the upper ~60 m of platform along a horizontal surface. Loosened bedrock slid seaward across the platform, and some of it accumulated as the lower debrite. Rock-water exchange induced landward-propagated tsunami(s), whose uprush and/or backwash deposited the upper turbidite, partly above sea level. Evidence for impact includes shockedquartz grains, an iridium anomaly, and reworked conodonts, all found only within the breccia. Because the Alamo breccia is not known outside of Nevada, and because the early Frasnian time of the Alamo event is not noted for accelerated extinctions, being ~3 m.y. before the Frasnian-Famennian impact(s) and biotic crisis, the impact was probably only of moderate size.</p>","language":"English","publisher":"GSA","usgsCitation":"Warme, J.E., and Sandberg, C., 1996, Alamo megabreccia: Record of a late devonian impact in southern Nevada: GSA Today, v. 6, no. 1, p. 1-7.","productDescription":"7 p.","startPage":"1","endPage":"7","costCenters":[{"id":35995,"text":"Geology, Geophysics, and Geochemistry Science Center","active":true,"usgs":true}],"links":[{"id":369548,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Nevada","otherGeospatial":"Alamo breccia","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -116.85607910156249,\n              36.712467243386264\n            ],\n            [\n              -114.04907226562499,\n              36.712467243386264\n            ],\n            [\n              -114.04907226562499,\n              39.04051963289309\n            ],\n            [\n              -116.85607910156249,\n              39.04051963289309\n            ],\n            [\n              -116.85607910156249,\n              36.712467243386264\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"6","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","contributors":{"authors":[{"text":"Warme, John E.","contributorId":219722,"corporation":false,"usgs":false,"family":"Warme","given":"John","email":"","middleInitial":"E.","affiliations":[{"id":6606,"text":"Colorado School of Mines","active":true,"usgs":false}],"preferred":false,"id":776070,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Sandberg, Charles sandberg@usgs.gov","contributorId":199124,"corporation":false,"usgs":true,"family":"Sandberg","given":"Charles","email":"sandberg@usgs.gov","affiliations":[{"id":35995,"text":"Geology, Geophysics, and Geochemistry Science Center","active":true,"usgs":true}],"preferred":true,"id":776071,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

To characterize the broadband wavefield near Puu Oo, we deployed a profile of three three-component broadband sensors in a 200 m long line about 1.5 km WSW of the active vent. During this period, Puu Oo maintained a constant, but very low level of activity. The digital data logger recorded the wavefield continuously in the frequency band between 0.01 and 40 Hz between June 25 and July 9, 1994. At the same time, local wind conditions along with air temperature and pressure were monitored by a portable digital weather station. On the basis of characteristic elements, such as waveform, spatial coherence between stations, particle motion and power spectra, the wavefield can be divided into three bands. The dominant signals in the frequency band between 0.01 and 0.1 Hz are not coherent among the stations. Their ground velocities correlate with the wind speed. The signals in the 0.1 to 0.5 Hz band are coherent across the profile and most probably represent a superposition of volcanic tremor and microseisms from the Pacific Ocean. Much of the energy above 0.5 Hz can be attributed to activity at the vent. Power spectra from recordings of the transverse components show complex peaks between 0.5 and 3 Hz which vary in amplitude due to site effects and distance. On the other hand, power spectra calculated from the radial components show a clearly periodic pattern of peaks at 1 Hz intervals for some time segments. A further remarkable feature of the power spectra is that they are highly stationary.</span></p>","language":"English","publisher":"Istituto Nazionale di Geofisica e Vulcanologia (INGV)","doi":"10.4401/ag-3973","usgsCitation":"Seidl, D., Hellweg, M., Okubo, P., and Rademacher, H., 1996, A preliminary survey of the broadband seismic wavefield at Puu Oo, the active vent of Kilauea volcano, Hawaii: Annali di Geofisica, v. 39, no. 2, p. 283-297, https://doi.org/10.4401/ag-3973.","productDescription":"15 p.","startPage":"283","endPage":"297","costCenters":[{"id":617,"text":"Volcano Science Center","active":true,"usgs":true}],"links":[{"id":479035,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.4401/ag-3973","text":"Publisher Index Page"},{"id":419045,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Hawaii","otherGeospatial":"Kilauea Volcano, Puu Oo","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -155.30651941412697,\n              19.448444250928404\n            ],\n            [\n              -155.30651941412697,\n              19.336840877798352\n            ],\n            [\n              -155.10324519723144,\n              19.336840877798352\n            ],\n            [\n              -155.10324519723144,\n              19.448444250928404\n            ],\n            [\n              -155.30651941412697,\n              19.448444250928404\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","volume":"39","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","contributors":{"authors":[{"text":"Seidl, D.","contributorId":102746,"corporation":false,"usgs":true,"family":"Seidl","given":"D.","email":"","affiliations":[],"preferred":false,"id":878150,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Hellweg, M.","contributorId":11344,"corporation":false,"usgs":true,"family":"Hellweg","given":"M.","email":"","affiliations":[],"preferred":false,"id":878151,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Okubo, P. 0000-0002-0381-6051","orcid":"https://orcid.org/0000-0002-0381-6051","contributorId":49432,"corporation":false,"usgs":true,"family":"Okubo","given":"P.","affiliations":[{"id":617,"text":"Volcano Science Center","active":true,"usgs":true}],"preferred":false,"id":878152,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Rademacher, H.","contributorId":93343,"corporation":false,"usgs":true,"family":"Rademacher","given":"H.","email":"","affiliations":[],"preferred":false,"id":878153,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

Four statistical methods using at-site data to adjust the regional equation predictions were developed to provide better local estimates. The four adjustment procedures are a single-factor adjustment, a regression of the observed data against the predicted values, a regression of the observed values against the predicted values and additional local independent variables, and a weighted combination of a local regression with the regional prediction. Data collected at five representative storm-runoff sites during 22 storms in Little Rock, Arkansas, were used to verify, and, when appropriate, adjust the regional regression equation predictions. Comparison of observed values of stormrunoff loads and mean concentrations to the predicted values from the regional regression equations for nine constituents (chemical oxygen demand, suspended solids, total nitrogen as N, total ammonia plus organic nitrogen as N, total phosphorus as P, dissolved phosphorus as P, total recoverable copper, total recoverable lead, and total recoverable zinc) showed large prediction errors ranging from 63 percent to more than several thousand percent. Prediction errors for 6 of the 18 regional regression equations were less than 100 percent and could be considered reasonable for water-quality prediction equations. The regression adjustment procedure was used to adjust five of the regional equation predictions to improve the predictive accuracy. For seven of the regional equations the observed and the predicted values are not significantly correlated. Thus neither the unadjusted regional equations nor any of the adjustments were appropriate. The mean of the observed values was used as a simple estimator when the regional equation predictions and adjusted predictions were not appropriate.","language":"English","publisher":"National Academy of Sciences","doi":"10.1177/0361198196152300117","issn":"03611981","usgsCitation":"Barks, C., 1996, Adjustment of regional regression equations for urban storm-runoff quality using at-site data: Transportation Research Record, v. 1523, no. 1, p. 141-146, https://doi.org/10.1177/0361198196152300117.","productDescription":"6 p.","startPage":"141","endPage":"146","costCenters":[],"links":[{"id":227124,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Arkansas","city":"Little Rock","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -92.38339893099169,\n              34.86270521495865\n            ],\n            [\n              -92.38339893099169,\n              34.68887462936465\n            ],\n            [\n              -92.16023799888761,\n              34.68887462936465\n            ],\n            [\n              -92.16023799888761,\n              34.86270521495865\n            ],\n            [\n              -92.38339893099169,\n              34.86270521495865\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","volume":"1523","issue":"1","noUsgsAuthors":false,"publicationDate":"1996-01-01","publicationStatus":"PW","scienceBaseUri":"5059e6f7e4b0c8380cd4775f","contributors":{"authors":[{"text":"Barks, C.

This report establishes and documents a formal policy for current (1995) quality assurance within the Idaho District of the U.S. Geological Survey. Quality assurance is formalized by describing district  organization and operational responsibilities, documenting the district quality-assurance policies, and describing district functions. The districts conducts its work through offices in Boise, Idaho Falls, Twin Falls, Sandpoint, and at the Idaho National Engineering Laboratory. Data-collection programs and interpretive studies are conducted by two operating units, and operational and technical assistance is provided by three support units: (1) Administrative Services advisors provide guidance on various personnel issues and budget functions, (2) computer and reports advisors provide guidance in their fields, and (3) discipline specialists provide technical advice and assistance to the district and to chiefs of various projects. The district's quality-assurance plan is based on an overall policy that provides a framework for defining the precision and accuracy of collected data. The plan is supported by a series of quality-assurance policy statements that describe responsibilities for specific operations in the district's program. The operations are program planning; project planning; project implementation; review and remediation; data collection; equipment calibration and maintenance; data processing and storage; data analysis, synthesis, and interpretation; report preparation and processing; and training. Activities of the district are systematically conducted under a hierarchy of supervision an management that is designed to ensure conformance with Water Resources Division goals quality assurance. The district quality-assurance plan does not describe detailed technical activities that are commonly termed \"quality-control procedures.\" Instead, it focuses on current policies, operations, and responsibilities that are implemented at the management level. Contents of the plan will be reviewed annually and updated as programs and operations change.","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/ofr95755","usgsCitation":"Packard, F.A., 1996, Quality-assurance plan for water-resources activities of the U.S. Geological Survey in Idaho: U.S. Geological Survey Open-File Report 95-755, iii, 22 p., https://doi.org/10.3133/ofr95755.","productDescription":"iii, 22 p.","numberOfPages":"25","costCenters":[{"id":343,"text":"Idaho Water Science Center","active":true,"usgs":true}],"links":[{"id":161370,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1995/0755/report-thumb.jpg"},{"id":60093,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1995/0755/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"country":"United States","state":"Idaho","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -117.24,41.99 ], [ -117.24,49.0 ], [ -111.04,49.0 ], [ -111.04,41.99 ], [ -117.24,41.99 ] ] ] } } ] }","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a87e4b07f02db64eb96","contributors":{"authors":[{"text":"Packard, F.

The stream-aquifer system consists of carbonate (limestone and dolomite) and elastic sediments, which define the Upper Floridan aquifer and Intermediate system, in hydraulic connection with the principal rivers of the basin and other surface-water features, natural and man made.</p><p>Separate digital models of the Upper Floridan aquifer and Intermediate system were con structed by using the U.S. Geological Survey's MODular Finite-Element model of two dimensional ground-water flow, based on conceptualizations of the stream-aquifer system, and calibrated to drought conditions of October 1986. Sensitivity analyses performed on the models indicated that aquifer hydraulic conductivity, lateral and vertical boundary flows, and pumpage have a strong influence on ground-water levels. Simulated pumpage increases in the Upper Floridan aquifer, primarily in the Dougherty Plain physiographic district of Georgia, caused significant reductions in aquifer discharge to streams that eventually flow to Lake Seminole and the Apalachicola River and Bay. Simulated pumpage increases greater than 3 times the October 1986 rates caused drying of some stream reaches and parts of the Upper Floridan aquifer in Georgia.</p><p>Water budgets prepared from simulation results indicate that ground-water discharge to streams and recharge by horizontal and vertical flow are the principal mechanisms for moving water through the flow system. The potential for changes in ground-water quality is high in areas where chemical constituents can be mobilized by these mechanisms. Less than 2 percent of ground-water discharge to streams comes from the Intermediate system; thus, it plays a minor role in the hydrodynamics of the stream aquifer

Residents south and west of Air Force Plant 4 and the Naval Air Station are concerned that contaminants might enter the underlying Paluxy aquifer, which provides water to the city of White Settlement, south of Air Force Plant 4, and to residents west of Air Force Plant 4. The U.S. Environmental Protection Agency has qualified Air Force Plant 4 for Superfund cleanup. </p><p>The pertinent geologic units include -A~rom oldest to youngest the Glen Rose, Paluxy, and Walnut Formations, Goodland Limestone, and terrace alluvial deposits. Except for the Glen Rose Formation, all units crop out at or near Air Force Plant 4 and the Naval Air Station. The terrace alluvial deposits, which nearly everywhere form the land surface, range from 0 to about 60 feet thick. These deposits comprise a mostly unconsolidated mixture of gravel, sand, silt, and clay. Mudstone and sandstone of the Paluxy Formation crop out north, west, and southwest of Lake Worth and total between about 130 and about 175 feet thick. </p><p>The terrace alluvial deposits and the Paluxy Formation comprise the terrace alluvial aquifer and the Paluxy aquifer, respectively. These aquifers are separated by the Goodland-Walnut confining unit, composed of the Goodland Limestone and (or) Walnut Formation. Below the Paluxy aquifer, the Glen Rose Formation forms the Glen Rose confining unit. </p><p>Water-level measurements during May 1993 and February 1994 from wells in the terrace alluvial aquifer indicate that, regionally, ground water flows toward the east-southeast beneath Air Force Plant 4 and the Naval Air Station. Locally, water appears to flow outward from ground-water mounds maintained by the localized infiltration of precipitation and reportedly by leaking water pipes and sanitary and (or) storm sewer lines beneath the assembly building at Air Force Plant 4. North of Farmers Branch, the terrace alluvial aquifer discharges into Lake Worth, Meandering Road Creek, Farmers Branch, and the West Fork Trinity River. South of Farmers Branch, ground water appears to flow mostly north-northeastward. Greater precipitation prior to the May 1993 measurements caused water levels to average approximately 5 ft higher in May 1993 than in February 1994. </p><p>Regional ground-water gradients indicate west to east-southeastward flow in the Paluxy aquifer, with a dominant southeastward component beneath Air Force Plant 4. Water-level maps for the Paluxy \"upper sand\" reveal an elongated groundwater mound beneath southeastern parts of Air Force Plant 4, which indicates a localized, vertical conduit through which contaminated water from the terrace alluvial aquifer might enter upper parts of the Paluxy aquifer. The Paluxy \"upper sand\" apparently is mostly unsaturated and hydraulically separated from the deeper, regionally extensive parts of the Paluxy aquifer, most of which are fully saturated. While water levels in the \"upper sand\"&nbsp;were as much as 10 ft higher in May 1993 than in February 1994, water levels in most deeper parts of the Paluxy aquifer were slightly higher in February 1994 than they were in May 1993.</p>","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Austin, TX","doi":"10.3133/wri964032","collaboration":"Prepared in cooperation with the U.S. Air Force Aeronautical Systems Center, Environmental Management Directorate","usgsCitation":"Rivers, G.A., Baker, E.T., and Coplin, L., 1996, Geohydrologic units and water-level conditions in the Terrace alluvial aquifer and Paluxy Aquifer, May 1993 and February 1994, near Air Force Plant 4, Fort Worth area, Texas: U.S. Geological Survey Water-Resources Investigations Report 96-4032, Document: iv, 13 p.; 6 Plates: 28.99 x 28.02 inches or smaller, https://doi.org/10.3133/wri964032.","productDescription":"Document: iv, 13 p.; 6 Plates: 28.99 x 28.02 inches or smaller","costCenters":[{"id":583,"text":"Texas Water Science Center","active":true,"usgs":true}],"links":[{"id":99334,"rank":400,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/wri/1996/4032/plate-1.pdf","size":"2339","linkFileType":{"id":1,"text":"pdf"}},{"id":99335,"rank":401,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/wri/1996/4032/plate-2.pdf","size":"1449","linkFileType":{"id":1,"text":"pdf"}},{"id":99336,"rank":402,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/wri/1996/4032/plate-3.pdf","size":"2137","linkFileType":{"id":1,"text":"pdf"}},{"id":120386,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/wri/1996/4032/report-thumb.jpg"},{"id":99337,"rank":403,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/wri/1996/4032/plate-4.pdf","size":"2335","linkFileType":{"id":1,"text":"pdf"}},{"id":99338,"rank":404,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/wri/1996/4032/plate-5.pdf","size":"1546","linkFileType":{"id":1,"text":"pdf"}},{"id":99339,"rank":405,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/wri/1996/4032/plate-6.pdf","size":"1582","linkFileType":{"id":1,"text":"pdf"}},{"id":82227,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/wri/1996/4032/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"country":"United States","state":"Texas","city":"Fort Worth","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b1be4b07f02db6a8dd1","contributors":{"authors":[{"text":"Rivers, Glen A.","contributorId":91154,"corporation":false,"usgs":true,"family":"Rivers","given":"Glen","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":230578,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Baker, Ernest T.

At this workshop, a group of magnetic specialists addressed this opportunity by discussing the need for high-altitude magnetic data and by formulating a preliminary operational plan to acquire such data. The high-altitude aeromagnetic survey would provide critical data needed to expand our knowledge of the geomagnetic field, with applications to a variety of earth science issues including geology, tectonics, core-processes, and rock-magnetism. Test flights with a cesium magnetometer indicate that the ER-2 has the potential to measure the magnetic field at an accuracy of 2 nT or better along flight lines. If the national ER-2 survey is carried out, the successful collection of high-altitude magnetic data hinges on establishing a consortium of federal and state agencies, private industry, and academic institutions to provide the identified resources.</p>","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/ofr96276","issn":"0094-9140","usgsCitation":"Hildenbrand, T., Blakely, R., Bracken, R.E., Edwards, L., Hardwick, D., Hinze, W.J., Labson, V., Malliot, H., Nabighian, M., Nilsson, B., Phillips, J., Quinn, J., and Roest, W., 1996, Rationale and preliminary operational plan for a high-altitude magnetic survey over the United States: U.S. Geological Survey Open-File Report 96-276, ii, 55 p., https://doi.org/10.3133/ofr96276.","productDescription":"ii, 55 p.","costCenters":[{"id":615,"text":"Volcano Hazards Program","active":true,"usgs":true}],"links":[{"id":153799,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1996/0276/report-thumb.jpg"},{"id":51540,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1996/0276/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a7fe4b07f02db6487fa","contributors":{"authors":[{"text":"Hildenbrand, T.G.","contributorId":83892,"corporation":false,"usgs":true,"family":"Hildenbrand","given":"T.G.","email":"","affiliations":[],"preferred":false,"id":187048,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Blakely, R.J. 0000-0003-1701-5236","orcid":"https://orcid.org/0000-0003-1701-5236","contributorId":70755,"corporation":false,"usgs":true,"family":"Blakely","given":"R.J.","affiliations":[],"preferred":false,"id":187046,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Bracken, R.
