New Jersey, to contamination by nitrate from the land surface. Statistical analyses were performed on data for 132 wells located throughout the Newark Basin. Concentrations of nitrate (as nitrogen) did not exceed the U.S. Environmental Protection Agency maximum contaminant level of 10 milligrams per liter (mg/L) in any of the water samples (U.S. Environmental Protection Agency, 1991). Variables that describe hydrogeology and well construction were found not to be statistically significant in relation to concentrations of nitrate. This finding can be attributed to the complex nature of flow in bedrock aquifers and mixing of water from shallow and deep water-bearing zones that occurs within these wells, which are constructed with long open intervals. Distributions of nitrate concentrations were significantly different among land-use groups on the basis of land use within both a 400- and an 800-m radius zone of the well. The median concentrations of nitrate (as N) in water from wells in predominantly urban-residential (2.5 mg/L) and agricultural areas (1.8 mg/L) were greater than the median concentration of nitrate in water from wells in predominantly undeveloped areas (0.5 mg/L).","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Water Resources Bulletin","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"American Water Resources Assoc","publisherLocation":"Herndon, VA, United States","doi":"10.1111/j.1752-1688.1996.tb04073.x","issn":"00431370","usgsCitation":"Clawges, R., and Vowinkel, E., 1996, Variables indicating nitrate contamination in Bedrock Aquifers, Newark Basin, New Jersey: Water Resources Bulletin, v. 32, no. 5, p. 1055-1066, https://doi.org/10.1111/j.1752-1688.1996.tb04073.x.","startPage":"1055","endPage":"1066","numberOfPages":"12","costCenters":[],"links":[{"id":267671,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1111/j.1752-1688.1996.tb04073.x"},{"id":227233,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"32","issue":"5","noUsgsAuthors":false,"publicationDate":"2007-06-08","publicationStatus":"PW","scienceBaseUri":"505bc14ae4b08c986b32a4f6","contributors":{"authors":[{"text":"Clawges, R.M.","contributorId":24779,"corporation":false,"usgs":true,"family":"Clawges","given":"R.M.","affiliations":[],"preferred":false,"id":378692,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Vowinkel, E.

The purpose of the deployment was to investigate factors relevant to seismic zonation in urban areas, such as site amplification, sedimentary basin effects, and the variability of ground motion over short baselines. We placed seismographs at 47 sites (not all concurrently) and recorded about 290 earthquakes with magnitudes up to 5.1 at five stations or more. We deployed widely spaced stations for profiles across the San Fernando Valley, as well as five dense arrays (apertures of 200 to 500 m) in areas of high damage, such as the collapsed Interstate 10 overpass, Sherman Oaks, and the collapsed parking garage at CalState Northridge. Aftershock data analysis indicates a correlation of site amplification with mainshock damage. We found several cases where the site amplification depended on the azimuth of the aftershock, possibly indicating focusing from basin structures. For the parking garage array, we found large ground-motion variabilities (a factor of 2) over 200-m distances for sites on the same mapped soil unit. Array analysis of the aftershock seismograms demonstrates that sizable arrivals after the direct<span>&nbsp;</span><i>S</i><span>&nbsp;</span>waves consist of surface waves traveling from the same azimuth as that of the epicenter. These surface waves increase the duration of motions and can have frequencies as high as about 4 Hz.

A wide range of science problems can be addressed at Mars. The planet formed in a different part of the solar system from the Earth and retains clues concerning compositional and environmental conditions in that part of the solar system when the planets formed. Mars has had a long and complex history that has involved almost as wide a range of processes as occurred on Earth. Elucidation of this history will require a comprehensive program of field mapping, geophysical sounding, in situ analyses, and return of samples to Earth that are representative of the planet's diversity. The origin and evolution of the Mars' atmosphere are very different from the Earth's, Mars having experienced major secular and cyclical changes in climate. Clues as to precisely how the atmosphere has evolved are embedded in its present chemistry, possibly in surface sinks of former atmosphere-forming volatiles, and in the various products of interaction between the atmosphere and surface. The present atmosphere also provides a means of testing general circulation models applicable to all planets. Although life is unlikely to be still extant on Mars, life may have started early in the planet's history. A major goal of any future exploration will, therefore, be to search for evidence of indigenous life.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"American Astronautical Society, Scientific Technology Series","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","issn":"02784017","usgsCitation":"Carr, M.H., 1996, Scientific objectives of human exploration of Mars: American Astronautical Society, Scientific Technology Series, v. 86, p. 515-535.","startPage":"515","endPage":"535","numberOfPages":"21","costCenters":[],"links":[{"id":227168,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"86","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505b8789e4b08c986b31652f","contributors":{"authors":[{"text":"Carr, M.

Thirty-five strong motion velocity records are inverted by this method over the frequency band from 0.1 to 1.0 Hz for the Northridge earthquake. Four regions of larger-amplitude slip are identified: one near the hypocenter at a depth of 17 km, a second west of the hypocenter at about the same depth, a third updip from the hypocenter at a depth of 10 km, and a fourth updip from the hypocenter and to the northwest. The results further show an initial fast rupture with a velocity of 2.8 to 3.0 km/s followed by a slow termination of the rupture with velocities of 2.0 to 2.5 km/s. The initial energetic rupture phase lasts for 3 s, extending out 10 km from the hypocenter. Slip near the hypocenter has a short risetime of 0.5 s, which increases to 1.5 s for the major slip areas removed from the hypocentral region. The energetic rupture phase is also shown to be the primary source of high-frequency radiation (1–15 Hz) by an inversion of acceleration envelopes. The same global search algorithm is used in the envelope inversion to calculate high-frequency radiation intensity on the fault and rupture time. The rupture timing from the low- and high-frequency inversions is similar, indicating that the high frequencies are produced primarily at the mainshock rupture front. Two major sources of high-frequency radiation are identified within the energetic rupture phase, one at the hypocenter and another deep source to the west of the hypocenter. The source at the hypocenter is associated with the initiation of rupture and the breaking of a high-stress-drop asperity and the second is associated with stopping of the rupture in a westerly direction.</span></p>","language":"English","publisher":"American Geophysical Union","doi":"10.1029/96JB01883","issn":"01480227","usgsCitation":"Hartzell, S., Liu, P., and Mendoza, C., 1996, The 1994 Northridge, California, earthquake: Investigation of rupture velocity, risetime, and high-frequency radiation: Journal of Geophysical Research B: Solid Earth, v. 101, no. 9, p. 20091-20108, https://doi.org/10.1029/96JB01883.","productDescription":"18 p.","startPage":"20091","endPage":"20108","numberOfPages":"18","costCenters":[],"links":[{"id":227277,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"101","issue":"9","noUsgsAuthors":false,"publicationDate":"1996-09-10","publicationStatus":"PW","scienceBaseUri":"505ba634e4b08c986b320f76","contributors":{"authors":[{"text":"Hartzell, S.","contributorId":12603,"corporation":false,"usgs":true,"family":"Hartzell","given":"S.","email":"","affiliations":[],"preferred":false,"id":378700,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Liu, P.","contributorId":98443,"corporation":false,"usgs":true,"family":"Liu","given":"P.","email":"","affiliations":[],"preferred":false,"id":378702,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Mendoza, C.","contributorId":82059,"corporation":false,"usgs":true,"family":"Mendoza","given":"C.","email":"","affiliations":[],"preferred":false,"id":378701,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

The fault system separates crystalline rocks of the Alexander terrane from metamorphic rocks of the Chugach terrane in Glacier Bay National Park. Mylonitic rocks in the zone record abundant evidence for dextral strike-slip motion along north-northwest-striking subvertical surfaces. Geochronologic data together with regional correlations of Chugach terrane rocks involved in the deformation constrain this movement between latest Cretaceous and Early Eocene (~50 Ma). These findings are in agreement with studies to the northwest and southeast along the Border Ranges fault system which show dextral strike-slip motion occurring between 58 and 50 Ma. Correlations between Glacier Bay plutons and rocks of similar ages elsewhere along the Border Ranges fault system suggest that as much as 700 km of dextral motion may have been accommodated by this structure. These observations are consistent with oblique convergence of the Kula plate during early Cenozoic and forearc slivering above an ancient subduction zone following late Mesozoic accretion of the Peninsular–Alexander–Wrangellia terrane to North America.</span></p>","language":"English","publisher":"Canadian Science Publishing","doi":"10.1139/e96-096","issn":"00084077","usgsCitation":"Smart, K., Pavlis, T., Sisson, V., Roeske, S.M., and Snee, L., 1996, The Border Ranges fault system in Glacier Bay National Park, Alaska: Evidence for major early Cenozoic dextral strike-slip motion: Canadian Journal of Earth Sciences, v. 33, no. 9, p. 1268-1282, https://doi.org/10.1139/e96-096.","productDescription":"15 p.","startPage":"1268","endPage":"1282","costCenters":[],"links":[{"id":227644,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Alaska","otherGeospatial":"Glacier Bay National Park","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -137.11638510129728,\n              58.862706667256305\n            ],\n            [\n              -136.72570704961922,\n              58.862706667256305\n            ],\n            [\n              -136.72570704961922,\n              58.99688217663305\n            ],\n            [\n              -137.11638510129728,\n              58.99688217663305\n            ],\n            [\n              -137.11638510129728,\n              58.862706667256305\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","volume":"33","issue":"9","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505ba6a8e4b08c986b321226","contributors":{"authors":[{"text":"Smart, K.J.","contributorId":43627,"corporation":false,"usgs":true,"family":"Smart","given":"K.J.","email":"","affiliations":[],"preferred":false,"id":379455,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Pavlis, T.L.","contributorId":94473,"corporation":false,"usgs":true,"family":"Pavlis","given":"T.L.","email":"","affiliations":[],"preferred":false,"id":379456,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Sisson, V.B.","contributorId":101104,"corporation":false,"usgs":false,"family":"Sisson","given":"V.B.","email":"","affiliations":[],"preferred":false,"id":379459,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Roeske, S.

Here the global distribution of lead isotopes in deep ocean water is presented as derived from dated (ca. 100 ka) surface layers of hydrogenetic Fe-Mn crusts. The results indicate that the radiogenic lead in North Atlantic deep water is probably supplied from the continents by river particulates, and that lead in Pacific deep water is similar to that characteristic of island and continental volcanic arcs. Despite a short residence time in deep water (80-100 a), the isotopes of lead appear to be exceedingly well mixed in the Pacific basin. There is no evidence for the import of North Atlantic deep water-derived lead into the Pacific ocean, nor into the North Indian Ocean. This implies that the short residence time of lead in deep water prohibits advection over such long distances. Consequently, any climate-induced changes in deep-water flow are not expected to result in major changes in the seawater Pb-isotope record of the Pacific Ocean.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Geochimica et Cosmochimica Acta","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1016/S0016-7037(96)00310-9","issn":"00167037","usgsCitation":"Von Blanckenburg, F., O’Nions, R.K., and Hein, J., 1996, Distribution and sources of pre-anthropogenic lead isotopes in deep ocean water from Fe-Mn crusts: Geochimica et Cosmochimica Acta, v. 60, no. 24, p. 4957-4963, https://doi.org/10.1016/S0016-7037(96)00310-9.","startPage":"4957","endPage":"4963","numberOfPages":"7","costCenters":[],"links":[{"id":205845,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/S0016-7037(96)00310-9"},{"id":227081,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"60","issue":"24","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a02a2e4b0c8380cd50138","contributors":{"authors":[{"text":"Von Blanckenburg, F.","contributorId":6199,"corporation":false,"usgs":true,"family":"Von Blanckenburg","given":"F.","email":"","affiliations":[],"preferred":false,"id":380237,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"O’Nions, R.

Record low barometric pressures were recorded in Augusta, Georgia (28.93 inches of mercury) and Columbia, South Carolina (28.63 inches of mercury) on March 13, 1993, and pressures returned to normal values (near 30 inches of mercury) within one day following these record lows. This relatively unusual event provided an opportunity to examine the attendant water-level response in continuously monitored ground-water wells in regional Atlantic Coastal Plain, Piedmont, and Blue Ridge aquifers in the Southeast. Water levels in all wells examined responded inversely to the short duration, extreme drop in barometric pressure. Barometric efficiencies (Δground-water level/Δbarometric-pressure level) calculated were dependent on depth to screened- or open-interval midpoint (highest correlation coefficient, r<sup>2</sup>= 0.89) and, to a lesser extent, total thickness of confining material above the aquifer tapped (highest r<sup>2</sup>= 0.65). Wells in crystalline-rock aquifers had a correlation with depth to open-interval midpoint (r<sup>2</sup>= 0.89) similar to the sedimentary aquifers examined. The magnitude of barometric efficiency was also strongly related to a well's increased distance from aquifer outcrop areas in the Cretaceous aquifers in South Carolina (r<sup>2</sup>= 0.95) and the upper Brunswick aquifer in Georgia (r<sup>2</sup>= 0.90), because these aquifers are more deeply buried toward the coast. This relation between barometric efficiency, well depth, and extent of confinement suggests that barometric efficiency determinations can provide useful information to hydrologists concerned with examining an aquifer's degree of confinement and corresponding isolation from land surface, particularly when the aquifer is used as a source for public supply.</p></div></div>","language":"English","publisher":"National Groundwater Association","doi":"10.1111/j.1745-6584.1996.tb02086.x","issn":"0017467X","usgsCitation":"Landmeyer, J., 1996, Aquifer Response to Record Low Barometric Pressures in the Southeastern United States: Groundwater, v. 34, no. 5, p. 917-924, https://doi.org/10.1111/j.1745-6584.1996.tb02086.x.","productDescription":"8 p.","startPage":"917","endPage":"924","numberOfPages":"8","costCenters":[],"links":[{"id":227321,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"34","issue":"5","noUsgsAuthors":false,"publicationDate":"2005-08-04","publicationStatus":"PW","scienceBaseUri":"5059ed1be4b0c8380cd49621","contributors":{"authors":[{"text":"Landmeyer, J.

We have developed a digital method for making measurements from aerial photographs which uses geographic information system (GIS) software, and primarily DOS-based personal computers. This method, which is based on the concept that a direct visual comparison can be made between images derived from two sets of aerial photographs taken at different times, was applied to the surface of the active portion of the Slumgullion earthflow in Colorado to determine horizontal displacement vectors from the movements of visually identifiable objects, such as trees and large rocks. Using this method, more of the slide surface can be mapped in a shorter period of time than using the standard photogrammetric approach. More than 800 horizontal displacement vectors were determined on the active earthflow surface using images produced by our digital photogrammetric technique and 1985 (1:12,000-scale) and 1990 (1:6,000-scale) aerial photographs. The resulting displacement field shows, with a 2-m measurement error (??? 10%), that the fastest moving portion of the landslide underwent 15-29 m of horizontal displacement between 1985 and 1990.

This formulation provides a unified representation of diverse sliding phenomena including slip weakening over a characteristic sliding distance D(c), apparent fracture energy at a rupture front, time- dependent healing after rapid slip, and various other transient and slip rate effects. Laboratory observations and theoretical models both indicate that earthquake nucleation is accompanied by long intervals of accelerating slip. Strains from the nucleation process on buried faults generally could not be detected if laboratory values of D, apply to faults in nature. However, scaling of D(c) is presently an open question and the possibility exists that measurable premonitory creep may precede some earthquakes. Earthquake activity is modeled as a sequence of earthquake nucleation events. In this model, earthquake clustering arises from sensitivity of nucleation times to the stress changes induced by prior earthquakes. The model gives the characteristic Omori aftershock decay law and assigns physical interpretation to aftershock parameters. The seismicity formulation predicts large changes of earthquake probabilities result from stress changes. Two mechanisms for foreshocks are proposed that describe observed frequency of occurrence of foreshock-mainshock pairs by time and magnitude. With the first mechanism, foreshocks represent a manifestation of earthquake clustering in which the stress change at the time of the foreshock increases the probability of earthquakes at all magnitudes including the eventual mainshock. With the second model, accelerating fault slip on the mainshock nucleation zone triggers foreshocks.","largerWorkTitle":"Proceedings of the National Academy of Sciences of the United States of America","language":"English","doi":"10.1073/pnas.93.9.3787","issn":"00278424","usgsCitation":"Dieterich, J.H., and Kilgore, B., 1996, Implications of fault constitutive properties for earthquake prediction, <i>in</i> Proceedings of the National Academy of Sciences of the United States of America, v. 93, no. 9, p. 3787-3794, https://doi.org/10.1073/pnas.93.9.3787.","startPage":"3787","endPage":"3794","numberOfPages":"8","costCenters":[],"links":[{"id":480179,"rank":10000,"type":{"id":41,"text":"Open Access External Repository Page"},"text":"External Repository"},{"id":205878,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1073/pnas.93.9.3787"},{"id":227251,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"93","issue":"9","noUsgsAuthors":false,"publicationDate":"1996-04-30","publicationStatus":"PW","scienceBaseUri":"505a3923e4b0c8380cd617fc","contributors":{"authors":[{"text":"Dieterich, James H.","contributorId":81614,"corporation":false,"usgs":true,"family":"Dieterich","given":"James","middleInitial":"H.","affiliations":[],"preferred":false,"id":379699,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Kilgore, B.","contributorId":59968,"corporation":false,"usgs":true,"family":"Kilgore","given":"B.","email":"","affiliations":[],"preferred":false,"id":379698,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

Application of a powerful multiple suppression technique improved the quality of occasional discontinuous, dipping primary reflections, but failed to substantially alter the non-reflective character of the blanking zone. Detailed analysis of amplitudes from original data and synthetic models show that the threshold for detecting primary energy in deep water of Lake Baikal occurs when the primary is about 14-20 dB less than the multiple energy. The blanking occurs because of anomalously low reflectivities of the deep sediments coupled with this 20 dB limitation in real data processing. The blanking cuts across seismic stratal boundaries, and is therefore probably unrelated to depositional lithologies. The deepest, early rift deposits, inferred to come from a mixed fluvial and lacustrine setting, do not easily explain the widespread and uniform character of the blanked deposits. More likely, blanking occurs because of processes or phenomena that physically alter the deposits, causing them to be non-reflective and/or highly attenuating. No single process explains all the observations, but a combination of diagenesis, overpressure, and the presence of dispersed free gas at sub-bottom depths of 1-2 km, offer plausible and possible conditions that contribute to blanking.

Three hundred kilometers of continuous marine gravity data were collected in the lake and integrated with land gravity data to a distance of more than 20 km around the lake. Analyses of the gravity data resulted in a free-air anomaly map, a variable density Bouguer anomaly map, and a horizontal first derivative map of the Bouguer anomaly. These maps, together with gravity models of profiles across the lake and the area south of it, were used to infer the geometry of the basins in this region and the main faults of the transform system. The Sea of Galilee can be divided into two units. The southern half is a pull-apart that extends to the Kinarot Valley, south of the lake, whereas the northern half was formed by rotational opening and transverse normal faults. The deepest part of the basinal area is located well south of the deepest bathymetric depression. This implies that the northeastern part of the lake, where the bathymetry is the deepest, is a young feature that is actively subsiding now. The pull-apart basin is almost symmetrical in the southern part of the lake and in the Kinarot Valley south of the lake. This suggests that the basin here is bounded by strike-slip faults on both sides. The eastern boundary fault extends to the northern part of the lake, while the western fault does not cross the northern part. The main factor controlling the structural complexity of this area is the interaction of the Dead Sea transform with a subperpendicular fault system and rotated blocks.","language":"English","publisher":"Wiley","doi":"10.1029/95JB03043","issn":"01480227","usgsCitation":"Ben-Avraham, Z., ten Brink, U., Bell, R., and Reznikov, M., 1996, Gravity field over the Sea of Galilee: Evidence for a composite basin along a transform fault: Journal of Geophysical Research B: Solid Earth, v. 101, no. 1, p. 533-544, https://doi.org/10.1029/95JB03043.","productDescription":"12 p.","startPage":"533","endPage":"544","costCenters":[{"id":678,"text":"Woods Hole Coastal and Marine Science Center","active":true,"usgs":true}],"links":[{"id":479047,"rank":1,"type":{"id":41,"text":"Open Access External Repository Page"},"url":"https://doi.org/10.7916/d8sq98ws","text":"External Repository"},{"id":227403,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"Israel ","otherGeospatial":"Sea of Galilee","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              35.50712585449219,\n              32.69428812316931\n            ],\n            [\n              35.66780090332031,\n              32.69428812316931\n            ],\n            [\n              35.66780090332031,\n              32.90783871693625\n            ],\n            [\n              35.50712585449219,\n              32.90783871693625\n            ],\n            [\n              35.50712585449219,\n              32.69428812316931\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"101","issue":"1","noUsgsAuthors":false,"publicationDate":"1996-01-10","publicationStatus":"PW","scienceBaseUri":"505a2a19e4b0c8380cd5aeb9","contributors":{"authors":[{"text":"Ben-Avraham, Z.","contributorId":68459,"corporation":false,"usgs":true,"family":"Ben-Avraham","given":"Z.","affiliations":[],"preferred":false,"id":380742,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"ten Brink, Uri S. 0000-0001-6858-3001 utenbrink@usgs.gov","orcid":"https://orcid.org/0000-0001-6858-3001","contributorId":127560,"corporation":false,"usgs":true,"family":"ten Brink","given":"Uri S.","email":"utenbrink@usgs.gov","affiliations":[{"id":186,"text":"Coastal and Marine Geology Program","active":true,"usgs":true},{"id":678,"text":"Woods Hole Coastal and Marine Science Center","active":true,"usgs":true}],"preferred":false,"id":380741,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Bell, R.","contributorId":26825,"corporation":false,"usgs":true,"family":"Bell","given":"R.","affiliations":[],"preferred":false,"id":380740,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Reznikov, M.","contributorId":72145,"corporation":false,"usgs":true,"family":"Reznikov","given":"M.","email":"","affiliations":[],"preferred":false,"id":380743,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

Results demonstrate that, for this soil, atrazine transport is directly related to the amount and timing of rain that follows spring applications of atrazine. Two other critical transport factors were important in wet years — [1] variability in atrazine application rate, and [2] atrazine degradation rates below the root zone. Results demonstrate that the coincidence of heavy rain soon after atrazine application can cause herbicide to move below the rooting zone into depths at which biodegradation rates are assumed to be low but are often unknown. Atrazine that reaches below the rooting zone and persists in the underlying soil can subsequently be transported into ground water as soil water drains, typically after the growing season. A frequency analysis of atrazine concentrations in subsurface drainage, combined with field data, demonstrates the relative importance of critical transport factors and confirms a need for definitive estimates of atrazine-degradation rates below the root zone. The analysis indicates that periodic leaching of atrazine can be expected for this soil when rainfall that exceeds 20 cm/mo coincides with atrazine presence in soil.</span></p>","language":"English","publisher":"ACS Publications","doi":"10.1021/bk-1996-0630.ch009","usgsCitation":"Eckhardt, D.A., and Wagenet, R.J., 1996, Estimation of the potential for atrazine transport in a silt loam soil: ACS Symposium Series, v. 630, p. 101-116, https://doi.org/10.1021/bk-1996-0630.ch009.","productDescription":"16 p.","startPage":"101","endPage":"116","numberOfPages":"16","costCenters":[],"links":[{"id":226996,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"630","noUsgsAuthors":false,"publicationDate":"2009-07-23","publicationStatus":"PW","scienceBaseUri":"505a0bb5e4b0c8380cd52837","contributors":{"authors":[{"text":"Eckhardt, D.

The approach consists of first hypothesizing alternative conceptual models of hydrogeology at the site on the basis of both quantitative data and qualitative information. The conceptual models are then expressed as two-dimensional numerical models of groundwater flow and solute transport, and model attributes controlling risk to the water supply are determined by simulation. Model predictions of response to a specific field test are made with each model that affects risk. Regions for effective measurement networks are then identified. Effective networks are those that capture sufficient information to determine which of the hypothesized models best describes the system with a minimum of measurement points.
