Two types of tufa are represented, informally defined as (1) an easily disaggregated, fine-grained mixture of calcite and quartz (friable tufa) in the southwest Tecopa Valley, and (2) hard, vuggy micrite, laminated carbonate, and carbonate-cemented sands and gravels (indurated tufa) along the eastern margin of Lake Tecopa. High δ<sup>18</sup>O<sub>VSMOW</sub> (Vienna standard mean ocean water) water values, field relations, and the texture of friable tufa suggest rapid nucleation of calcite as subaqueous, fault- controlled groundwater discharge mixed with high-pH, hypersaline lake water. Variations between δ<sup>18</sup>O<sub>VSMOW</sub> and δ<sup>13</sup>C<sub>PDB</sub> (Peedee belemnite) values relative to other closed basin lakes such as the Great Salt Lake and Lake Lahontan suggest similarities in climatic and hydrologic settings. Indurated tufa, also fault controlled, formed mounds and associated feeder systems as well as stratabound carbonate-cemented ledges. Both deposits represent discharge of deeply circulated, high total dissolved solids, and high <i>p</i>CO<sub>2</sub> regional groundwater with kinetic enrichments of as much as several per mil for δ<sup>18</sup>O<sub>VSMOW</sub> values.\n\nField relations show that indurated tufa represents episodic discharge, and U-series ages imply that discharge was correlated with cold, wet climate episodes. In response to both the breaching of the Tecopa basin and a modern arid climate, most discharge has changed from fault-controlled locations near basin margins to topographic lows of the Amargosa River drainage at elevations 30–130 m lower. Because of episodic climate change, spring flows may have relocated from basin margin to basin center multiple times.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"GSA Bulletin","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Geological Society of America","doi":"10.1130/0016-7606(2001)113<0659:PROSDI>2.0.CO;2","usgsCitation":"Nelson, S.T., Karlsson, H.R., Paces, J.B., Tingey, D.G., Ward, S., and Peters, M.T., 2001, Paleohydrologic record of spring deposits in and around Pleistocene pluvial Lake Tecopa, southeastern California: GSA Bulletin, v. 113, no. 5, p. 659-670, https://doi.org/10.1130/0016-7606(2001)113<0659:PROSDI>2.0.CO;2.","productDescription":"12 p.","startPage":"659","endPage":"670","numberOfPages":"12","costCenters":[{"id":218,"text":"Denver Federal Center","active":false,"usgs":true}],"links":[{"id":281581,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":281580,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1130/0016-7606(2001)113<0659:PROSDI>2.0.CO;2"}],"country":"United States","state":"California","city":"Tecopa","otherGeospatial":"Lake Tecopa","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -116.286772,35.793291 ], [ -116.286772,35.899551 ], [ -116.10947,35.899551 ], [ -116.10947,35.793291 ], [ -116.286772,35.793291 ] ] ] } } ] }","volume":"113","issue":"5","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"53cd6a7ce4b0b290851034a1","contributors":{"authors":[{"text":"Nelson, Stephen T.","contributorId":32078,"corporation":false,"usgs":true,"family":"Nelson","given":"Stephen","email":"","middleInitial":"T.","affiliations":[],"preferred":false,"id":489396,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Karlsson, Haraldur R.","contributorId":80180,"corporation":false,"usgs":true,"family":"Karlsson","given":"Haraldur","email":"","middleInitial":"R.","affiliations":[],"preferred":false,"id":489399,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Paces, James B. 0000-0002-9809-8493 jbpaces@usgs.gov","orcid":"https://orcid.org/0000-0002-9809-8493","contributorId":2514,"corporation":false,"usgs":true,"family":"Paces","given":"James","email":"jbpaces@usgs.gov","middleInitial":"B.","affiliations":[{"id":318,"text":"Geosciences and Environmental Change Science Center","active":true,"usgs":true}],"preferred":true,"id":489394,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Tingey, David G.","contributorId":67406,"corporation":false,"usgs":true,"family":"Tingey","given":"David","email":"","middleInitial":"G.","affiliations":[],"preferred":false,"id":489398,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Ward, Stephen","contributorId":44072,"corporation":false,"usgs":true,"family":"Ward","given":"Stephen","affiliations":[],"preferred":false,"id":489397,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Peters, Mark T.","contributorId":22243,"corporation":false,"usgs":true,"family":"Peters","given":"Mark","email":"","middleInitial":"T.","affiliations":[],"preferred":false,"id":489395,"contributorType":{"id":1,"text":"Authors"},"rank":6}]}}

We present the results of 2 field trials using artificial tortoise models in 3 size classes. The trials were conducted on 2 occasions on an area south of Las Vegas, Nevada, where the density of the test population was known. In the first trials, conducted largely by experienced biologists who had been involved in tortoise surveys for many years, the density of adult tortoise models was well estimated (-3.9% bias), while the bias was higher (-20%) for subadult tortoise models. The bias for combined data was -12.0%. The bias was largely attributed to the failure to detect all tortoise models on or near the transect centerline. The second trials were conducted with a group of largely inexperienced student volunteers and used somewhat different searching methods, and the results were similar to the first trials. Estimated combined density of subadult and adult tortoise models had a negative bias (-7.3%), again attributable to failure to detect some models on or near the centerline. Experience in desert tortoise biology, either comparing the first and second trials or in the second trial with 2 experienced biologists versus 16 novices, did not have an apparent effect on the quality of the data or the accuracy of the estimates. Observer training, specific to line transect sampling, and field testing are important components of a reliable survey. Line transect sampling represents a viable method for largescale monitoring of populations of desert tortoise; however, field protocol must be improved to assure the key assumptions are met.</span></p>","language":"English","publisher":"Wiley","publisherLocation":"Washington","doi":"10.2307/3803111","usgsCitation":"Anderson, D.R., Burnham, K.P., Lubow, B., Thomas, L.E., Corn, P., Medica, P.A., and Marlow, R., 2001, Field trials of line transect methods applied to estimation of desert tortoise abundance: Journal of Wildlife Management, v. 65, no. 3, p. 583-597, https://doi.org/10.2307/3803111.","productDescription":"15 p.","startPage":"583","endPage":"597","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[{"id":481,"text":"Northern Rocky Mountain Science Center","active":true,"usgs":true}],"links":[{"id":311505,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Nevada","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -115.45806884765625,\n              35.66845370835343\n            ],\n            [\n              -115.45806884765625,\n              36.12900165569652\n            ],\n            [\n              -114.88128662109375,\n              36.12900165569652\n            ],\n            [\n              -114.88128662109375,\n              35.66845370835343\n            ],\n            [\n              -115.45806884765625,\n              35.66845370835343\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"65","issue":"3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"564daf4ce4b0112df6c62e16","contributors":{"authors":[{"text":"Anderson, David R.","contributorId":92722,"corporation":false,"usgs":true,"family":"Anderson","given":"David","email":"","middleInitial":"R.","affiliations":[],"preferred":false,"id":580195,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Burnham, Kenneth P.","contributorId":95025,"corporation":false,"usgs":true,"family":"Burnham","given":"Kenneth","email":"","middleInitial":"P.","affiliations":[{"id":189,"text":"Colorado Cooperative Fish and Wildlife Research Unit","active":false,"usgs":true}],"preferred":false,"id":580196,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Lubow, Bruce C.","contributorId":131076,"corporation":false,"usgs":false,"family":"Lubow","given":"Bruce C.","affiliations":[{"id":7230,"text":"Natural Resource Ecology Laboratory, Colorado State University","active":true,"usgs":false}],"preferred":false,"id":580197,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Thomas, L.

Here we show that the &delta;<sup>56</sup>Fe of Fe dissolved from a silicate soil mineral by siderophore-producing bacteria is as much as 0.8% lighter than bulk Fe in the mineral. A smaller isotopic shift is observed for Fe released abiotically by two chelates, and the magnitude of the shift increases with affinity of the ligand for Fe, consistent with a kinetic isotope effect during hydrolysis of Fe at the mineral surface.  Fe dissolved abiotically without chelates shows no isotopic shift. The &delta;<sup>56</sup>Fe of the exchange fraction on soil grains is also lighter by ~0.6%-1% than Fe from both hornblende and iron oxyhydroxides. The kinetic isotope effect is therefore preserved in open systems such as soils. when recorded in the rock record, Fe isotopic fractionation could document Fe transport by organic molecules or by microbes where such entities were present in the geologic past.","language":"English","publisher":"Geological Society of America","doi":"10.1130/0091-7613(2001)029<0535:FOFIBS>2.0.CO;2","usgsCitation":"Brantley, S., Liermann, L., and Bullen, T.D., 2001, Fractionation of Fe isotopes by soil microbes and organic acids: Geology, v. 29, no. 6, p. 535-538, https://doi.org/10.1130/0091-7613(2001)029<0535:FOFIBS>2.0.CO;2.","productDescription":"4 p.","startPage":"535","endPage":"538","costCenters":[{"id":436,"text":"National Research Program - Eastern Branch","active":true,"usgs":true},{"id":589,"text":"Toxic Substances Hydrology Program","active":true,"usgs":true}],"links":[{"id":281190,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1130/0091-7613(2001)029<0535:FOFIBS>2.0.CO;2"},{"id":281191,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"29","issue":"6","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"53cd5a40e4b0b290850f93aa","contributors":{"authors":[{"text":"Brantley, Susan L.","contributorId":38461,"corporation":false,"usgs":true,"family":"Brantley","given":"Susan L.","affiliations":[],"preferred":false,"id":488632,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Liermann, Laura","contributorId":98632,"corporation":false,"usgs":true,"family":"Liermann","given":"Laura","email":"","affiliations":[],"preferred":false,"id":488633,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Bullen, Thomas D. 0000-0003-2281-1691 tdbullen@usgs.gov","orcid":"https://orcid.org/0000-0003-2281-1691","contributorId":1969,"corporation":false,"usgs":true,"family":"Bullen","given":"Thomas","email":"tdbullen@usgs.gov","middleInitial":"D.","affiliations":[{"id":438,"text":"National Research Program - Western Branch","active":true,"usgs":true}],"preferred":true,"id":488631,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

Catchment-scale atrazine and nutrient transport processes after agricultural application are still poorly understood, and predicting episodic streamwater composition remains an elusive goal. We instrumented a 1.2-km<sup>2</sup> agricultural catchment near Harrisonburg, Virginia, and examined streamwater, overland flow, soil water, groundwater, and rainfall during the summer of 1998. Storm chemographs demonstrated different patterns for constituents derived primarily from weathering (silica and calcium), compared to constituents derived primarily from early spring land applications (nitrate, atrazine, DOC, potassium, chloride, and sulfate). During storms, the concentrations of silica and calcium decreased, the atrazine response was variable, and the concentrations of nitrate, DOC, potassium, chloride, and sulfate increased; the elevated nitrate signal lagged several hours behind the other elevated constituents. Graphical and statistical analyses indicated a relatively stable spring-fed baseflow was modified by a mixture of overland flow and soil water. A rapid, short-duration overland-flow pulse dominated the streamflow early in the event and contributed most of the potassium, DOC, chloride, suspended sediment, and atrazine. A longer-duration soil–water pulse dominated the streamflow later in the event and contributed the nitrate as well as additional potassium, DOC, sulfate, and atrazine. The contributions to the episodic streamflow were quantified using a flushing model in which overland-flow and soil–water concentrations decreased exponentially with time during an episode. Flushing time constants for the overland-flow and soil–water reservoirs were calculated on a storm-by-storm basis using separate tracers for each time-variable reservoir. Initial component concentrations were estimated through regression analyses. Mass-balance calculations were used for flow separations and to predict the observed streamwater composition. Model forecasts indicated that reduced fertilizer and pesticide application (rather than elimination of overland-flow or soil–water contributions) was necessary to improve the episodic streamwater composition. This study provides important additional understanding of the catchment-scale processes by which land-applied pesticides and nutrients can move through agricultural systems.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Hydrology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Elsevier","doi":"10.1016/S0022-1694(01)00497-8","usgsCitation":"Hyer, K., Hornberger, G., and Herman, J.S., 2001, Processes controlling the episodic streamwater transport of atrazine and other agrichemicals in an agricultural watershed: Journal of Hydrology, v. 254, no. 1-4, p. 47-66, https://doi.org/10.1016/S0022-1694(01)00497-8.","productDescription":"20 p.","startPage":"47","endPage":"66","numberOfPages":"20","costCenters":[],"links":[{"id":285152,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":285151,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/S0022-1694(01)00497-8"}],"country":"United States","state":"Virginia","otherGeospatial":"Muddy Creek","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -78.8909,38.2642 ], [ -78.8909,38.6171 ], [ -78.2909,38.6171 ], [ -78.2909,38.2642 ], [ -78.8909,38.2642 ] ] ] } } ] }","volume":"254","issue":"1-4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5355952de4b0120853e8c167","contributors":{"authors":[{"text":"Hyer, Kenneth kenhyer@usgs.gov","contributorId":2701,"corporation":false,"usgs":true,"family":"Hyer","given":"Kenneth","email":"kenhyer@usgs.gov","affiliations":[{"id":614,"text":"Virginia Water Science Center","active":true,"usgs":true}],"preferred":false,"id":492160,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Hornberger, George M.","contributorId":63894,"corporation":false,"usgs":true,"family":"Hornberger","given":"George M.","affiliations":[],"preferred":false,"id":492162,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Herman, Janet S.","contributorId":62138,"corporation":false,"usgs":true,"family":"Herman","given":"Janet","email":"","middleInitial":"S.","affiliations":[],"preferred":false,"id":492161,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

These normal faults are downthrown to the west, and the Colorado River crosses these faults as it flows west in the Grand Canyon. Cosmogenic <sup>3</sup>He (<sup>3</sup>He<sub>c</sub>) dates on basalt flows and related landforms are used to calculate vertical displacement rates for these faults. The two faults cross unruptured alluvial fans dated as 3 ka (Toroweap) and 8 ka (Hurricane), and 10 other landforms that range in age from 30 to 400 ka are displaced. Middle and late Quaternary displacement rates of the Toroweap and Hurricane faults are 70–180 and 70–170 m/m.y., respectively. On the basis of these rates, the combined displacement of 580 m on these faults could have occurred in the past 3 to 5 m.y. All <sup>3</sup>He<sub>c</sub> dates are younger than existing K- Ar dates and are consistent with new <sup>40</sup>Ar/<sup>39</sup>Ar dates and existing thermoluminescence (TL) dates on basalt flows. These different dating techniques may be combined in an analysis of displacement rates. Downcutting rates for the Colorado River in the eastern Grand Canyon (400 m/m.y.) are at least double the downcutting rates west of the faults (70–160 m/m.y.). Faulting probably increased downcutting in the eastern Grand Canyon relative to downcutting in the western Grand Canyon during the late Quaternary.","language":"English","publisher":"Geological Society of America","doi":"10.1130/0091-7613(2001)029<1035:DROTTA>2.0.CO;2","usgsCitation":"Fenton, C.R., Webb, R., Pearthree, P.A., Cerling, T.E., and Poreda, R.J., 2001, Displacement rates on the Toroweap and Hurricane faults: Implications for Quaternary downcutting in the Grand Canyon, Arizona: Geology, v. 29, no. 11, p. 1035-1038, https://doi.org/10.1130/0091-7613(2001)029<1035:DROTTA>2.0.CO;2.","productDescription":"4 p.","startPage":"1035","endPage":"1038","numberOfPages":"4","costCenters":[],"links":[{"id":282831,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Arizona","otherGeospatial":"Grand Canyon","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -114.0572,35.6882 ], [ -114.0572,36.5318 ], [ -111.828,36.5318 ], [ -111.828,35.6882 ], [ -114.0572,35.6882 ] ] ] } } ] }","volume":"29","issue":"11","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"53cd5548e4b0b290850f63a3","contributors":{"authors":[{"text":"Fenton, Cassandra R.","contributorId":58915,"corporation":false,"usgs":true,"family":"Fenton","given":"Cassandra","email":"","middleInitial":"R.","affiliations":[],"preferred":false,"id":491036,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Webb, Robert H. rhwebb@usgs.gov","contributorId":1573,"corporation":false,"usgs":false,"family":"Webb","given":"Robert H.","email":"rhwebb@usgs.gov","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":491032,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Pearthree, Philip A.","contributorId":17363,"corporation":false,"usgs":true,"family":"Pearthree","given":"Philip","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":491033,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Cerling, Thure E.","contributorId":22822,"corporation":false,"usgs":true,"family":"Cerling","given":"Thure","email":"","middleInitial":"E.","affiliations":[],"preferred":false,"id":491034,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Poreda, Robert J.","contributorId":37797,"corporation":false,"usgs":true,"family":"Poreda","given":"Robert","email":"","middleInitial":"J.","affiliations":[],"preferred":false,"id":491035,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}}

One of the primary goals of this framework document is to provide sufficient background and information for Department of the Interior (DOI) bureau stakeholders and other clients to determine the potential for DSS development. Such an understanding can assist them in carrying out effective land planning and management practices. This document provides a definition of DSS and its characteristics and capabilities. It proceeds to describe issues related to meeting resource managers needs, such as the needs for specific applications, customer requirements, information and technology transfer, user support, and institutionalization. Using the decision process as a means to guide DSS development and determine users needs is also discussed. We conclude with information on method to evaluate DSS development efforts and recommended procedures for verification and validation.&nbsp;</p>","language":"English","publisher":"United States

The prestack depth-migrated reflection image contains near-vertical reflections aligned with the active fault trace. The fault is vertical in the upper 0.5 kilometer, then dips about 70° to the southwest to at least 1 kilometer subsurface. This dip reconciles the difference between the computed locations of earthquakes and the surface fault trace. The seismic velocity cross section shows strong lateral variations. Relatively low velocity (10 to 30%), high electrical conductivity, and low density indicate a 1-kilometer-wide vertical wedge of porous sediment or fractured rock immediately southwest of the active fault trace.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Science","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"American Association for the Advancement of Science","doi":"10.1126/science.1065100","usgsCitation":"Hole, J., Catchings, R.D., St. Clair, K., Rymer, M.J., Okaya, D.A., and Carney, B., 2001, Steep-dip seismic imaging of the shallow San Andreas Fault near Parkfield: Science, v. 294, no. 5546, p. 1513-1515, https://doi.org/10.1126/science.1065100.","productDescription":"3 p.","startPage":"1513","endPage":"1515","numberOfPages":"3","costCenters":[{"id":237,"text":"Earthquake Science Center","active":true,"usgs":true}],"links":[{"id":285145,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":285144,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1126/science.1065100"}],"country":"United States","state":"California","city":"Parkfield","otherGeospatial":"San Andreas Fault","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -120.7288,35.984 ], [ -120.7288,35.7083 ], [ -120.2628,35.7083 ], [ -120.2628,35.984 ], [ -120.7288,35.984 ] ] ] } } ] }","volume":"294","issue":"5546","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"53559567e4b0120853e8c20b","contributors":{"authors":[{"text":"Hole, J.A.","contributorId":103422,"corporation":false,"usgs":true,"family":"Hole","given":"J.A.","email":"","affiliations":[],"preferred":false,"id":492147,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Catchings, R.

The greatest proportion (by mass) of grit in gizzards of Sandhill Cranes consisted of particles with a minimum dimension of 2.36-4.75 mm. Grit particles in swans were much smaller, with the most prevalent (by mass) being 0.6-1.18 mm. The greatest dimension of the largest grit particle found in cranes and swans was 17.4 mm and 14.0 mm, respectively. The U.S. Environmental Protection Agency has proposed a ban on lead fishing weights of &le;25.4 mm in any dimension. Based on the size of grit particles that we found in gizzards of Sandhill Cranes, Mute Swans, and Tundra Swans, we believe it is unlikely that individuals of those species would ingest, as grit, lead

About 2.5 million people of the greater Seattle-Tacoma metropolitan area can see Mount Rainier on clear days, and 150,000 live in areas swept by lahars and floods that emanated from the volcano during the last 6,000 years (Figure 1). These lahars include the voluminous Osceola Mudflow that floors the lowlands south of Seattle and east of Tacoma, and which was generated by massive volcano flank-collapse. Mount Rainier's last eruption was a light dusting of ash in 1894; minor pumice last erupted between 1820 and 1854; and the most recent large eruptions we know of were about 1100 and 2300 years ago, according to reports from the U.S. Geological Survey.</span></p>","language":"English","publisher":"Wiley","doi":"10.1029/01EO00057","usgsCitation":"Sisson, T.W., Vallance, J., and Pringle, P.T., 2001, Progress made in understanding Mount Rainier's hazards: Eos, Transactions, American Geophysical Union, v. 82, no. 9, p. 113-120, https://doi.org/10.1029/01EO00057.","productDescription":"8 p.","startPage":"113","endPage":"120","numberOfPages":"8","costCenters":[{"id":615,"text":"Volcano Hazards Program","active":true,"usgs":true}],"links":[{"id":478834,"rank":2,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1029/01eo00057","text":"Publisher Index Page"},{"id":282392,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Washington","otherGeospatial":"Mount Rainier","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -121.876709,46.787719 ], [ -121.876709,46.939905 ], [ -121.638906,46.939905 ], [ -121.638906,46.787719 ], [ -121.876709,46.787719 ] ] ] } } ] }","volume":"82","issue":"9","noUsgsAuthors":false,"publicationDate":"2006-10-19","publicationStatus":"PW","scienceBaseUri":"53cd6e50e4b0b29085105b22","contributors":{"authors":[{"text":"Sisson, T.

Among the invading species are winter annuals, biennials, cool-season perennials, warm-season perennials, vines, shrubs, and trees. Many of these species have been deliberately introduced and widely planted; some are still used for range improvement, pastures, lawns, and as ornamentals, though many are listed as state or federal noxious weeds. Others have been greatly facilitated by widespread land disturbance. Historically, fire has been a major selective force in the evolution of temperate grasslands. Further, prescribed fire is commonly used as a method of ecological management for native grassland communities as well as in conjunction with restoration efforts. Within this context, it is important to understand how invasive species will interact with natural and prescribed fire regimes. In this paper, we consider what is known about how exotic species that invade temperate grasslands relate to fire. The primary issues addressed for each species are (1) Does fire appear to enhance colonization? (2) To what degree does fire affect the survival of plants? (3) Are plants that are burned able to regrow following fire and, if so, how rapidly can they recover? (4) How important is competition with native species to the response to fire? and (5) What effect does an invasive species have on the characteristics of the fire regime? For many species, results are preliminary, incomplete, or inconsistent among studies. For this reason, many of the conclusions drawn for individual species must be considered preliminary. Based on analyses of individual species, a conceptual framework is presented for considering how invasive plants may interact with fire when they invade an ecosystem. The major categories of influences are the native community, the fire regime, growth conditions for both invasive and native species, and influences that disturbances, human impacts, and landscape characteristics have had in the past and will have in the future. The examples considered in this paper provide support for a few, tentative generalizations. First, among our current worst invaders of temperate grasslands, adaptation to fire is quite variable. Some species are not well adapted to burning and can be easily eliminated; other species are better adapted but can still be eliminated if fire occurs during periods of particular vulnerability and/or at high frequency. There is a set of species that is extremely well adapted to fire and will not be eliminated through burning alone. Second, competitive interactions with native species play a crucial role in the success of nonnative invaders. In cases where differential burn responses between invasive and native species can be exploited, and adequate populations of native dominant species are present, fire can sometimes tip the competitive balance away from invasives. Third, there are a few invasive species that have exceptional attributes and for which there are no easy solutions. The ability of cheatgrass (<i>Bromus tectorum</i>) to enhance fire, the ability of Chinese tallow (<i>Triadica sebifera</i>) to suppress fire, and the ability of leafy spurge (<i>Euphorbia esula</i>) to resprout from repeated injury make these species exceptional threats to native diversity. Finally, the available information for many invasive species is very incomplete, partic- ularly with regard to how fire affects competitive interactions with the native community. There is much more we need to know if we are to consistently predict how invasive species will respond to fire and how burning can best be used to manage for natural diversity.</span></p>","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"Proceedings of the Invasive Species Workshop : the role of fire in the control and spread of invasive species.

In response to extensive use of the aquifer--nearly 21 million gallons per day in 1986--water levels have declined to about 100 feet below sea level near Atlantic City and remain below sea level throughout the coastal areas of southern New Jersey, raising concerns about the potential for saltwater intrusion into well fields.</p>\n<br/>\n<p>Water levels in the Atlantic City 800-foot sand have declined in response to pumping from the aquifer since the 1890's. Water levels in the first wells drilled into the Atlantic City 800-foot sand were above land surface, and water flowed continuously from the wells. By 1986, water levels were below sea level throughout most of the coastal areas. Under current conditions, wells near the coast derive most of their supply from lateral flow contributed from the unconfined part of the aquifer northwest of the updip limit of the confining unit that overlies the Atlantic City 800- foot sand. Ground water also flows laterally from offshore areas and leaks vertically through the overlying and underlying confining units into the Atlantic City 800-foot sand. The decline in water levels upsets the historical equilibrium between freshwater and ancient saltwater in offshore parts of the aquifer and permits the lateral movement of saltwater toward pumping centers. The rate of movement is accelerated as the decline in water levels increases. The chloride concentration of aquifer water 5.3 miles offshore of Atlantic City was measured as 77 mg/L (milligrams per liter) in 1985 at a U.S. Geological Survey observation well. Salty water has also moved toward wells in Cape May County. The confined, regional nature of the Atlantic City 800-foot sand permits water levels in Cape May County to decline in response to pumping in Atlantic County and vice versa. Historically, chloride concentrations as great as 1 ,510 mg/L have been reported for water in a former supply well in southern Cape May County. These data indicate that salty water has moved inland in Cape May County. Analysis of the chloride-concentration data indicates that ground water with a chloride concentration of 250 mg/L is within 4 miles of supply wells in Stone Harbor, Cape May County, and is about 10 miles offshore of supply wells near Atlantic City.</p>\n<br/>\n<p>Results of numerical simulations of ground-water flow were analyzed to determine the effects of four water-supply alternatives on water levels, the flow budget, and potential saltwater movement toward pumping centers during 1986-2040. In the supply alternatives, pumpage is (1) held constant at 1986 rates of pumpage; (2) increased by 35 percent at 1986 locations; (3) increased by 35 percent, but with relocation of some supply wells further inland; and (4) increased by 35 percent but with some of the increase derived from inland wells tapping the Kirkwood-Cohansey aquifer system rather than the Atlantic City 800-foot sand. Inland relocation of supply wells closer to the updip limit of the overlying confining unit results in the smallest decline in water levels and the smallest rate of ground-water flow between the offshore location of salty water and coastal supply wells. Increased pumpage from coastal supply wells results in the greatest water-level declines and the greatest increase in the rate of ground-water flow from offshore to coastal wells.</p>\n<br/>\n<p>Flow of undesirable salty ground water from offshore locations remains nearly the same as for current (1986) conditions when pumping rates do not change, and the flow-rate increase is smallest for the relocated pumpage (fourth) alternative. In comparing the two conditions of a 35-percent increase in pumpage, the flow from undesirable salty water positions is lessened and flow from the unconfined aquifer is increased when some of the pumping centers are relocated farther inland. Ground water from the 250-mg/L isochlor position does not reach supply wells during any simulated conditions predicted for 1986-2040. The analysis of the simulation, however, includes only advective freshwater flow from an estimated 250-mg/L isochlor position and does not include density effects. A chloride concentration data-collection network could be designed to monitor for saltwater intrusion and serve as an early warning system for the communities of southern Cape May County and the coastal communities near Atlantic City. Data from existing offshore wells could continue to serve as an early warning system for the Atlantic City area; however, observation wells south of Stone Harbor, in the Wildwood area, would be useful as an early warning system for southern Cape May County.</p>","language":"English","publisher":"New Jersey Department of Environmental Protection, Division of Science, Research and Technology, Geological Survey","publisherLocation":"Trenton, NJ","collaboration":"Prepared by the United States Geological Survey in cooperation with the New Jersey Department of Environmental Protection, Division of Science, Research and Technology, Geological Survey","usgsCitation":"McAuley, S.D., Barringer, J., Paulachok, G.N., Clark, J.S., and Zapecza, O.S., 2001, Ground-water flow and quality in the Atlantic City 800-foot sand, New Jersey: New Jersey Geological Survey Report GSR 41, vi, 86 p.","productDescription":"vi, 86 p.","numberOfPages":"94","costCenters":[],"links":[{"id":290121,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":290120,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/unnumbered/70114185/report.pdf"}],"projection":"Universal Transverse Mercator Projection, Zone 18","country":"United States","state":"New Jersey","city":"Atlantic City","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -75.4266,38.7969 ], [ -75.4266,40.246 ], [ -73.7842,40.246 ], [ -73.7842,38.7969 ], [ -75.4266,38.7969 ] ] ] } } ] }","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"53aa9df2e4b065055fab1669","contributors":{"authors":[{"text":"McAuley, Steven D.","contributorId":81895,"corporation":false,"usgs":true,"family":"McAuley","given":"Steven","email":"","middleInitial":"D.","affiliations":[],"preferred":false,"id":495260,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Barringer, Julia L.","contributorId":59419,"corporation":false,"usgs":true,"family":"Barringer","given":"Julia L.","affiliations":[],"preferred":false,"id":495259,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Paulachok, Gary N. gnpaulac@usgs.gov","contributorId":3500,"corporation":false,"usgs":true,"family":"Paulachok","given":"Gary","email":"gnpaulac@usgs.gov","middleInitial":"N.","affiliations":[],"preferred":true,"id":495257,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Clark, Jeffrey S.","contributorId":85222,"corporation":false,"usgs":true,"family":"Clark","given":"Jeffrey","email":"","middleInitial":"S.","affiliations":[],"preferred":false,"id":495261,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Zapecza, Otto S. ozapecza@usgs.gov","contributorId":3687,"corporation":false,"usgs":true,"family":"Zapecza","given":"Otto","email":"ozapecza@usgs.gov","middleInitial":"S.","affiliations":[],"preferred":true,"id":495258,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}}
