PAGER automatically estimates the number of people exposed to severe ground shaking and the shaking intensity at affected cities. Accompanying maps of the epicentral region show the population distribution and estimated ground-shaking intensity. A regionally specific comment describes the inferred vulnerability of the regional building inventory and, when available, lists recent nearby earthquakes and their effects. PAGER's results are posted on the USGS Earthquake Program Web site (http://earthquake.usgs.gov/), consolidated in a concise one-page report, and sent in near real-time to emergency responders, government agencies, and the media. Both rapid and accurate results are obtained through manual and automatic updates of PAGER's content in the hours following significant earthquakes. These updates incorporate the most recent estimates of earthquake location, magnitude, faulting geometry, and first-hand accounts of shaking. PAGER relies on a rich set of earthquake analysis and assessment tools operated by the USGS and contributing Advanced National Seismic System (ANSS) regional networks. A focused research effort is underway to extend PAGER's near real-time capabilities beyond population exposure to quantitative estimates of fatalities, injuries, and displaced population.","language":"ENGLISH","publisher":"U.S. Geological Survey","doi":"10.3133/ofr20091131","usgsCitation":"Earle, P.S., Wald, D.J., Jaiswal, K., Allen, T.I., Hearne, M.G., Marano, K., Hotovec, A.J., and Fee, J., 2009, Prompt Assessment of Global Earthquakes for Response (PAGER): A System for Rapidly Determining the Impact of Earthquakes Worldwide: U.S. Geological Survey Open-File Report 2009-1131, iii, 15 p., https://doi.org/10.3133/ofr20091131.","productDescription":"iii, 15 p.","onlineOnly":"Y","costCenters":[{"id":595,"text":"U.S. Geological Survey","active":false,"usgs":true}],"links":[{"id":118507,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/ofr_2009_1131.jpg"},{"id":12800,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/of/2009/1131/","linkFileType":{"id":5,"text":"html"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a9ae4b07f02db65d9db","contributors":{"authors":[{"text":"Earle, Paul S. pearle@usgs.gov","contributorId":840,"corporation":false,"usgs":true,"family":"Earle","given":"Paul","email":"pearle@usgs.gov","middleInitial":"S.","affiliations":[{"id":300,"text":"Geologic Hazards Science Center","active":true,"usgs":true}],"preferred":false,"id":302766,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Wald, David J. 0000-0002-1454-4514 wald@usgs.gov","orcid":"https://orcid.org/0000-0002-1454-4514","contributorId":795,"corporation":false,"usgs":true,"family":"Wald","given":"David","email":"wald@usgs.gov","middleInitial":"J.","affiliations":[{"id":300,"text":"Geologic Hazards Science Center","active":true,"usgs":true}],"preferred":true,"id":302765,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Jaiswal, Kishor S.","contributorId":61120,"corporation":false,"usgs":true,"family":"Jaiswal","given":"Kishor S.","affiliations":[],"preferred":false,"id":302770,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Allen, Trevor I.","contributorId":60722,"corporation":false,"usgs":true,"family":"Allen","given":"Trevor","email":"","middleInitial":"I.","affiliations":[],"preferred":false,"id":302769,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Hearne, Michael G.","contributorId":88445,"corporation":false,"usgs":true,"family":"Hearne","given":"Michael","email":"","middleInitial":"G.","affiliations":[],"preferred":false,"id":302772,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Marano, Kristin D.","contributorId":54683,"corporation":false,"usgs":true,"family":"Marano","given":"Kristin D.","affiliations":[],"preferred":false,"id":302768,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Hotovec, Alicia J.","contributorId":88039,"corporation":false,"usgs":true,"family":"Hotovec","given":"Alicia","email":"","middleInitial":"J.","affiliations":[],"preferred":false,"id":302771,"contributorType":{"id":1,"text":"Authors"},"rank":7},{"text":"Fee, Jeremy jmfee@usgs.gov","contributorId":3775,"corporation":false,"usgs":true,"family":"Fee","given":"Jeremy","email":"jmfee@usgs.gov","affiliations":[{"id":300,"text":"Geologic Hazards Science Center","active":true,"usgs":true}],"preferred":false,"id":302767,"contributorType":{"id":1,"text":"Authors"},"rank":8}]}} ,{"id":97649,"text":"ofr20091127 - 2009 - Geophysical delineation of Mg-rich ultramafic rocks for mineral carbon sequestration","interactions":[],"lastModifiedDate":"2018-05-03T16:25:09","indexId":"ofr20091127","displayToPublicDate":"2009-07-03T00:00:00","publicationYear":"2009","noYear":false,"publicationType":{"id":18,"text":"Report"},"publicationSubtype":{"id":5,"text":"USGS Numbered Series"},"seriesTitle":{"id":330,"text":"Open-File Report","code":"OFR","onlineIssn":"2331-1258","printIssn":"0196-1497","active":true,"publicationSubtype":{"id":5}},"seriesNumber":"2009-1127","title":"Geophysical delineation of Mg-rich ultramafic rocks for mineral carbon sequestration","docAbstract":"

This presentation covers three general topics: (1) description of a new geologic compilation of the United States that shows the location of magnesium-rich ultramafic rocks in the conterminous United States; (2) conceptual illustration of the potential ways that ultramafic rocks could be used to sequester carbon dioxide; and (3) description of ways to use geophysical data to refine and extend the geologic mapping of ultramafic rocks and to better characterize their mineralogy.

The geophysical focus of this research is twofold. First, we illustrate how airborne magnetic data can be used to map the shallow subsurface geometry of ultramafic rocks for the purpose of estimating the volume of rock material available for mineral CO2 sequestration. Secondly, we explore, on a regional to outcrop scale, how magnetic mineralogy, as expressed in magnetic anomalies, may vary with magnesium minerals, which are the primary minerals of interest for CO2 sequestration.

An inversion of gravity data indicates that thin (<1 km) basin deposits cover much of the Preserve, except for Ivanpah Valley and the Woods Mountains volcanic center. Localized areas of Cenozoic deposits thicker than 500 m are predicted beneath parts of Lanfair Valley, Fenner Valley, near Kelso, Soda Lake, and southeast of Baker. Along the southern margin of the Mojave National Preserve, basins greater than 1 km deep are located between the Clipper and Marble Mountains, between the Marble and Bristol Mountains, and south of the Bristol Mountains near Amboy. Both density and magnetization boundaries defined by horizontal-gradient analyses coincide locally with Cenozoic faults and can be used to extend these faults beneath cover. Magnetization boundaries also highlight the structural grain within the crystalline rocks and may serve as a proxy for fracturing, an important source of permeability within the generally impermeable basement rocks, thus mapping potential groundwater pathways through and along the mountain ranges in the study area.","language":"ENGLISH","publisher":"U.S. Geological Survey","doi":"10.3133/ofr20091117","collaboration":"Prepared in cooperation with National Park Service","usgsCitation":"Langenheim, V., Biehler, S., Negrini, R., Mickus, K., Miller, D., and Miller, R.J., 2009, Gravity and Magnetic Investigations of the Mojave National Preserve and Adjacent Areas, California and Nevada (Version 1.0): U.S. Geological Survey Open-File Report 2009-1117, Report: iii, 25 p.; ReadMe; Metadata; Data; Rock Properties, https://doi.org/10.3133/ofr20091117.","productDescription":"Report: iii, 25 p.; ReadMe; Metadata; Data; Rock Properties","onlineOnly":"Y","additionalOnlineFiles":"Y","costCenters":[{"id":314,"text":"Geophysics Unit of Menlo Park, CA (GUMP)","active":false,"usgs":true}],"links":[{"id":118502,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/ofr_2009_1117.jpg"},{"id":12794,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/of/2009/1117/","linkFileType":{"id":5,"text":"html"}}],"geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -116.5,34.5 ], [ -116.5,35.75 ], [ -114.75,35.75 ], [ -114.75,34.5 ], [ -116.5,34.5 ] ] ] } } ] }","edition":"Version 1.0","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4abae4b07f02db6722d7","contributors":{"authors":[{"text":"Langenheim, V.E. 0000-0003-2170-5213","orcid":"https://orcid.org/0000-0003-2170-5213","contributorId":54956,"corporation":false,"usgs":true,"family":"Langenheim","given":"V.E.","affiliations":[{"id":312,"text":"Geology, Minerals, Energy, and Geophysics Science Center","active":true,"usgs":true}],"preferred":false,"id":302748,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Biehler, S.","contributorId":57560,"corporation":false,"usgs":true,"family":"Biehler","given":"S.","affiliations":[],"preferred":false,"id":302749,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Negrini, R.","contributorId":26390,"corporation":false,"usgs":true,"family":"Negrini","given":"R.","email":"","affiliations":[],"preferred":false,"id":302747,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Mickus, K.","contributorId":24457,"corporation":false,"usgs":true,"family":"Mickus","given":"K.","email":"","affiliations":[],"preferred":false,"id":302746,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Miller, D.

The primary Se source is drainage from surrounding seleniferous marine sedimentary formations. An ecosystem-scale model was employed as a tool to assist development of a site-specific Se objective for the region. The model visualizes outcomes of different exposure scenarios in terms of bioaccumulation in predators using partitioning coefficients, trophic transfer factors, and site-specific data for food-web inhabitants and particulate phases. Predicted Se concentrations agreed well with field observations, validating the use of the model as realistic tool for testing exposure scenarios. Using the fish tissue and bird egg guidelines suggested by regulatory agencies, allowable water concentrations were determined for different conditions and locations in the watershed and the bay. The model thus facilitated development of a site-specific Se objective that was locally relevant and provided a basis for step-by-step implementation of source control.","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/ofr20091114","usgsCitation":"Presser, T.S., and Luoma, S.N., 2009, Modeling of selenium for the San Diego Creek watershed and Newport Bay, California (Version 1.0): U.S. Geological Survey Open-File Report 2009-1114, v, 48 p., https://doi.org/10.3133/ofr20091114.","productDescription":"v, 48 p.","onlineOnly":"Y","costCenters":[{"id":589,"text":"Toxic Substances Hydrology Program","active":true,"usgs":true},{"id":633,"text":"Water Resources National Research Program","active":false,"usgs":true}],"links":[{"id":197973,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"},{"id":12782,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/of/2009/1114/","linkFileType":{"id":5,"text":"html"}}],"country":"United States","state":"California","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -118,33.5 ], [ -118,33.8 ], [ -117.8,33.8 ], [ -117.8,33.5 ], [ -118,33.5 ] ] ] } } ] }","edition":"Version 1.0","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b05e4b07f02db6998cf","contributors":{"authors":[{"text":"Presser, Theresa S. 0000-0001-5643-0147 tpresser@usgs.gov","orcid":"https://orcid.org/0000-0001-5643-0147","contributorId":2467,"corporation":false,"usgs":true,"family":"Presser","given":"Theresa","email":"tpresser@usgs.gov","middleInitial":"S.","affiliations":[{"id":438,"text":"National Research Program - Western Branch","active":true,"usgs":true}],"preferred":true,"id":302728,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Luoma, Samuel N. 0000-0001-5443-5091 snluoma@usgs.gov","orcid":"https://orcid.org/0000-0001-5443-5091","contributorId":2287,"corporation":false,"usgs":true,"family":"Luoma","given":"Samuel","email":"snluoma@usgs.gov","middleInitial":"N.","affiliations":[{"id":438,"text":"National Research Program - Western Branch","active":true,"usgs":true}],"preferred":true,"id":302727,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}} ,{"id":97627,"text":"ofr20091070 - 2009 - Ocean carbon and biogeochemistry scoping workshop on terrestrial and coastal carbon fluxes in the Gulf of Mexico, St. Petersburg, FL, May 6-8, 2008","interactions":[],"lastModifiedDate":"2023-12-07T15:56:24.572823","indexId":"ofr20091070","displayToPublicDate":"2009-06-25T00:00:00","publicationYear":"2009","noYear":false,"publicationType":{"id":18,"text":"Report"},"publicationSubtype":{"id":5,"text":"USGS Numbered Series"},"seriesTitle":{"id":330,"text":"Open-File Report","code":"OFR","onlineIssn":"2331-1258","printIssn":"0196-1497","active":true,"publicationSubtype":{"id":5}},"seriesNumber":"2009-1070","title":"Ocean carbon and biogeochemistry scoping workshop on terrestrial and coastal carbon fluxes in the Gulf of Mexico, St. Petersburg, FL, May 6-8, 2008","docAbstract":"Despite their relatively small surface area, ocean margins may have a significant impact on global biogeochemical cycles and, potentially, the global air-sea fluxes of carbon dioxide. Margins are characterized by intense geochemical and biological processing of carbon and other elements and exchange large amounts of matter and energy with the open ocean. The area-specific rates of productivity, biogeochemical cycling, and organic/inorganic matter sequestration are high in coastal margins, with as much as half of the global integrated new production occurring over the continental shelves and slopes (Walsh, 1991; Doney and Hood, 2002; Jahnke, in press). However, the current lack of knowledge and understanding of biogeochemical processes occurring at the ocean margins has left them largely ignored in most of the previous global assessments of the oceanic carbon cycle (Doney and Hood, 2002). A major source of North American and global uncertainty is the Gulf of Mexico, a large semi-enclosed subtropical basin bordered by the United States, Mexico, and Cuba. Like many of the marginal oceans worldwide, the Gulf of Mexico remains largely unsampled and poorly characterized in terms of its air-sea exchange of carbon dioxide and other carbon fluxes.\r\n In May 2008, the Ocean Carbon and Biogeochemistry Scoping Workshop on Terrestrial and Coastal Carbon Fluxes in the Gulf of Mexico was held in St. Petersburg, FL, to address the information gaps of carbon fluxes associated with the Gulf of Mexico and to offer recommendations to guide future research. The meeting was attended by over 90 participants from over 50 U.S. and Mexican institutions and agencies. The Ocean Carbon and Biogeochemistry program (OCB; http://www.us-ocb.org/) sponsored this workshop with support from the National Science Foundation, the National Oceanic and Atmospheric Administration, the National Aeronautics and Space Administration, the U.S. Geological Survey, and the University of South Florida.\r\n The goal of the workshop was to bring together researchers from multiple disciplines studying terrestrial, aquatic, and marine ecosystems to discuss the state of knowledge in carbon fluxes in the Gulf of Mexico, data gaps, and overarching questions in the Gulf of Mexico system. The discussions at the workshop were intended to stimulate integrated studies of marine and terrestrial biogeochemical cycles and associated ecosystems that will help to establish the role of the Gulf of Mexico in the carbon cycle and how it might evolve in the face of environmental change. The information derived from the plenary sessions, questions, and recommendations formulated by the participants will drive future research projects. Further discussion of carbon dynamics is needed to address scales of variability, the infrastructure required for study, and the modeling framework for cross-system integration. \r\n During the workshop, participants discussed and provided a number of priorities and recommendations, which are listed on p. 2 of the report.\r\n Participants recognized that the key to understanding the Gulf of Mexico system requires international collaboration with scientists from countries adjacent to the Gulf of Mexico. Improved collaboration across existing research community boundaries will be critical and should be encouraged by the funding agencies.","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/ofr20091070","usgsCitation":"Robbins, L.L., Coble, P., Clayton, T., and Cai, W., 2009, Ocean carbon and biogeochemistry scoping workshop on terrestrial and coastal carbon fluxes in the Gulf of Mexico, St. Petersburg, FL, May 6-8, 2008: U.S. Geological Survey Open-File Report 2009-1070, iv, 46 p., https://doi.org/10.3133/ofr20091070.","productDescription":"iv, 46 p.","onlineOnly":"Y","temporalStart":"2008-05-06","temporalEnd":"2008-05-08","costCenters":[{"id":275,"text":"Florida Integrated Science Center","active":false,"usgs":true},{"id":574,"text":"St. Petersburg Coastal and Marine Science Center","active":true,"usgs":true}],"links":[{"id":12773,"rank":2,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/of/2009/1070/","linkFileType":{"id":5,"text":"html"}},{"id":195623,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4af4e4b07f02db692021","contributors":{"authors":[{"text":"Robbins, L.

In 2002, 2003, and 2004 we surveyed for plants and vertebrates (amphibians, reptiles, birds, and mammals) at Chiricahua NM to document the presence of species within the boundaries of the monument. Because we used repeatable study designs and standardized field methods, these inventories can serve as the first step in a biological monitoring program for the monument. This report is also the first summary of previous research from the monument and therefore it provides an important overview of survey efforts to date. We used data from our inventory and previous research to compile complete species lists for the monument and to assess inventory completeness. \r\n\r\nWe recorded a total of 424 species, including 37 not previously found at the monument (Table 1). We found 10 species of non-native plants and one non-native mammal. Most non-native plants were found along the western boundary of the monument. Based on a review of our inventory and past research at the monument, there have been a total of 1,137 species of plants and vertebrates found at the monument. We believe the inventories of vascular plants and vertebrates are nearly complete and that the monument has one of the most complete inventories of any unit in the Sonoran Desert Network. \r\n\r\nThe mammal community at the monument had the highest species richness (69 species) and the amphibian and reptile community was among the lowest species richness (33 species) of any park in the Sonoran Desert Network. Species richness of the plant and bird communities was intermediate. Among the important determinants of species richness for all groups is the geographic location of the monument at the intergrades between the Chihuahuan and Sonoran deserts with influences from the Great Plains and Madrean ecological provinces. The diversity of plants results from a wide variety of soil types and aspects (from cool, moist canyons to semi-desert grasslands to pine forests). In turn, the vertebrate communities respond to this diversity of vegetation, topography, and microsites. For example, for each taxonomic group we found that some species were only associated with a single community type, most often the riparian areas or semi-desert grasslands. The area of highest species richness for most groups was the western-most portion of Bonita Canyon. The low species richness observed in the amphibian and reptile community was likely because the monument is at the elevational edge of the more species-rich semi-desert grasslands. \r\n\r\nThis report includes management implications from our work and suggestions for how the monument staff might better maintain or enhance the unique biological resources of the monument. We suggest additional inventory, monitoring, and research studies and we identify components of our effort that could be improved upon, either through the application of new techniques (e.g., establishment of vegetation monitoring plots) or by extending the temporal and/or spatial scope of our work.","language":"ENGLISH","publisher":"U.S. Geological Survey","doi":"10.3133/ofr20081023","collaboration":"Prepared in cooperation with the University of Arizona School of Natural Resources","usgsCitation":"Powell, B., Schmidt, C., Halvorson, W., and Anning, P., 2009, Vascular Plant and Vertebrate Inventory of Chiricahua National Monument (Version 1.0): U.S. Geological Survey Open-File Report 2008-1023, xiv, 104 p., https://doi.org/10.3133/ofr20081023.","productDescription":"xiv, 104 p.","onlineOnly":"Y","temporalStart":"2002-01-01","temporalEnd":"2004-12-31","costCenters":[{"id":568,"text":"Southwest Biological Science Center","active":true,"usgs":true}],"links":[{"id":195952,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"},{"id":12770,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/of/2008/1023/","linkFileType":{"id":5,"text":"html"}}],"geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -109.4,31.9 ], [ -109.4,21.1 ], [ -109.2,21.1 ], [ -109.2,31.9 ], [ -109.4,31.9 ] ] ] } } ] }","edition":"Version 1.0","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b05e4b07f02db699908","contributors":{"authors":[{"text":"Powell, Brian F.","contributorId":25644,"corporation":false,"usgs":true,"family":"Powell","given":"Brian F.","affiliations":[],"preferred":false,"id":302692,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Schmidt, Cecilia A.","contributorId":25645,"corporation":false,"usgs":true,"family":"Schmidt","given":"Cecilia A.","affiliations":[],"preferred":false,"id":302693,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Halvorson, William L.","contributorId":97194,"corporation":false,"usgs":true,"family":"Halvorson","given":"William L.","affiliations":[],"preferred":false,"id":302695,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Anning, Pamela","contributorId":45789,"corporation":false,"usgs":true,"family":"Anning","given":"Pamela","affiliations":[],"preferred":false,"id":302694,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}} ,{"id":97613,"text":"ofr20091111 - 2009 - Analytical Results for Agricultural Soils Samples from a Monitoring Program Near Deer Trail, Colorado (USA)","interactions":[],"lastModifiedDate":"2012-02-10T00:11:48","indexId":"ofr20091111","displayToPublicDate":"2009-06-17T00:00:00","publicationYear":"2009","noYear":false,"publicationType":{"id":18,"text":"Report"},"publicationSubtype":{"id":5,"text":"USGS Numbered Series"},"seriesTitle":{"id":330,"text":"Open-File Report","code":"OFR","onlineIssn":"2331-1258","printIssn":"0196-1497","active":true,"publicationSubtype":{"id":5}},"seriesNumber":"2009-1111","title":"Analytical Results for Agricultural Soils Samples from a Monitoring Program Near Deer Trail, Colorado (USA)","docAbstract":"Since late 1993, Metro Wastewater Reclamation District of Denver (Metro District, MWRD), a large wastewater treatment plant in Denver, Colorado, has applied Grade I, Class B biosolids to about 52,000 acres of nonirrigated farmland and rangeland near Deer Trail, Colorado, USA. In cooperation with the Metro District in 1993, the U.S. Geological Survey (USGS) began monitoring groundwater at part of this site. In 1999, the USGS began a more comprehensive monitoring study of the entire site to address stakeholder concerns about the potential chemical effects of biosolids applications to water, soil, and vegetation. This more comprehensive monitoring program has recently been extended through 2010. Monitoring components of the more comprehensive study include biosolids collected at the wastewater treatment plant, soil, crops, dust, alluvial and bedrock groundwater, and stream bed sediment. Soils for this study were defined as the plow zone of the dry land agricultural fields - the top twelve inches of the soil column. This report presents analytical results for the soil samples collected at the Metro District farm land near Deer Trail, Colorado, during three separate sampling events during 1999, 2000, and 2002. Soil samples taken in 1999 were to be a representation of the original baseline of the agricultural soils prior to any biosolids application. The soil samples taken in 2000 represent the soils after one application of biosolids to the middle field at each site and those taken in 2002 represent the soils after two applications. There have been no biosolids applied to any of the four control fields. The next soil sampling is scheduled for the spring of 2010.\r\n\r\nPriority parameters for biosolids identified by the stakeholders and also regulated by Colorado when used as an agricultural soil amendment include the total concentrations of nine trace elements (arsenic, cadmium, copper, lead, mercury, molybdenum, nickel, selenium, and zinc), plutonium isotopes, and gross alpha and beta activity (Colorado Department of Public Health and Environment, Hazardous Materials and Waste Management Division, 1997; Colorado Department of Public Health and Environment,1998; U.S. Environmental Protection Agency, 1993). Since these were the identified priority parameters for the biosolids, the soils have the same set of priority parameters. Although the composite soils' priority analytes have been reported earlier to Metro District, the remaining elemental datasets for both the composite soils samples and selected fields' individual subsamples' data are presented here for the first time. More information about the other monitoring components is presented elsewhere in the literature (http://co.water.usgs.gov/projects/CO406/CO406.html).\r\n\r\nIn general, the objective of each component of the study was to determine whether concentrations of priority parameters (1) were higher than regulatory limits, (2) were increasing with time, and(or) (3) were significantly higher in biosolids-applied areas than in a similar farmed area where biosolids were not applied.\r\n\r\nThe method chosen for sampling the soils proved to be an efficient and reliable representation of the average composition of each field. This was shown by analyzing individual subsamples, averaging the resulting values, and then comparing the values to the composited samples' values. The soil chemistry shows distinct differences between the two sites, most likely due to the different underlying parent material.\r\n\r\nBiosolids data were used to compile an inorganic-chemical biosolids signature that can be contrasted with the geochemical signature of the agricultural soils for this site. The biosolids signature and an understanding of the geology and hydrology of the site can be used to separate biosolids effects from natural geochemical effects. Elements of particular interest for a biosolids signature after application in the soils include bismuth, copper, silver, mercury, and phosphorus.

In support of the nowcast, data were collected during the recreational season of 2008 to validate and refine predictive models at two Lake Erie beaches. Predictive models yield data on the probability that the single-sample bathing-water standard for E. coli will be exceeded. Field personnel collected or compiled data on Escherichia coli (E. coli) concentrations as well as variables expected to affect these concentrations, including manual and automated measurements of turbidity, wave height, and water temperature; lake level; and radar and airport rainfall amounts. Two new variables were measured during 2008 - photosynthetically-active radiation at Huntington (Bay Village) and foreshore head at Edgewater (Cleveland). (The foreshore is a strip of land along a body of water between low and high water marks.)\r\n\r\nThe performance of the nowcast was monitored during 2008. The Huntington nowcast yielded a greater percentage of correct responses (84.9 percent) than did the previous day's E. coli concentration (75.2 percent). In contrast, at Edgewater, the nowcast yielded a slightly higher percentage of correct responses (61.0 percent) as compared to the previous day's E. coli concentration (56.5 percent), but both percentages were relatively low. Lake levels in 2008 were significantly higher than levels in the data used to develop the Edgewater models (2004-7), confounding their abilities to provide correct responses. At Edgewater during 2008, the strongest relation (as measured by Pearson's correlation) was between E. coli concentrations and the difference in foreshore head over the past 24 hours (r=0.48), a variable not included in the models. At Huntington, photosynthetically-active radiation on the previous day showed a significant negative relation to E. coli concentrations (r=-0.33) during 2008.\r\n\r\nRefined models were developed for Huntington and Edgewater using data collected from 2005-8. The refined models included the variables wave height, log turbidity, radar or airport rainfall, and day of the year in various combinations for different dated segments of the recreational season. Water-resource managers will determine which models to apply to the Ohio Nowcast for issuing water-quality advisories in 2009.","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/ofr20091066","usgsCitation":"Francy, D.S., Bertke, E.E., and Darner, R.A., 2009, Testing and refining the Ohio Nowcast at two Lake Erie beaches— 2008: U.S. Geological Survey Open-File Report 2009-1066, iv, 20 p., https://doi.org/10.3133/ofr20091066.","productDescription":"iv, 20 p.","temporalStart":"2008-05-01","temporalEnd":"2008-09-30","costCenters":[{"id":513,"text":"Ohio Water Science Center","active":true,"usgs":true}],"links":[{"id":389993,"rank":3,"type":{"id":36,"text":"NGMDB Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_86751.htm"},{"id":12756,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/of/2009/1066/","linkFileType":{"id":5,"text":"html"}},{"id":196212,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"}],"country":"United States","state":"Ohio","otherGeospatial":"Lake Erie","geographicExtents":"{\n \"type\": \"FeatureCollection\",\n \"features\": [\n {\n \"type\": \"Feature\",\n \"properties\": {},\n \"geometry\": {\n \"type\": \"Polygon\",\n \"coordinates\": [\n [\n [\n -82.012939453125,\n 41.46742831254425\n ],\n [\n -81.6888427734375,\n 41.46742831254425\n ],\n [\n -81.6888427734375,\n 41.51474739095224\n ],\n [\n -82.012939453125,\n 41.51474739095224\n ],\n [\n -82.012939453125,\n 41.46742831254425\n ]\n ]\n ]\n }\n }\n ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4ad8e4b07f02db6849d4","contributors":{"authors":[{"text":"Francy, Donna S. 0000-0001-9229-3557 dsfrancy@usgs.gov","orcid":"https://orcid.org/0000-0001-9229-3557","contributorId":1853,"corporation":false,"usgs":true,"family":"Francy","given":"Donna","email":"dsfrancy@usgs.gov","middleInitial":"S.","affiliations":[{"id":513,"text":"Ohio Water Science Center","active":true,"usgs":true},{"id":35860,"text":"Ohio-Kentucky-Indiana Water Science Center","active":true,"usgs":true}],"preferred":true,"id":302662,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Bertke, Erin E. eebertke@usgs.gov","contributorId":1934,"corporation":false,"usgs":true,"family":"Bertke","given":"Erin","email":"eebertke@usgs.gov","middleInitial":"E.","affiliations":[],"preferred":true,"id":302663,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Darner, Robert A. 0000-0003-1333-8265 radarner@usgs.gov","orcid":"https://orcid.org/0000-0003-1333-8265","contributorId":1972,"corporation":false,"usgs":true,"family":"Darner","given":"Robert","email":"radarner@usgs.gov","middleInitial":"A.","affiliations":[{"id":513,"text":"Ohio Water Science Center","active":true,"usgs":true},{"id":35860,"text":"Ohio-Kentucky-Indiana Water Science Center","active":true,"usgs":true}],"preferred":true,"id":302664,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}} ,{"id":97603,"text":"ofr20091084 - 2009 - Potentiometric Surface of the Upper Patapsco Aquifer in Southern Maryland, September 2007","interactions":[],"lastModifiedDate":"2023-03-10T12:50:27.338005","indexId":"ofr20091084","displayToPublicDate":"2009-06-16T00:00:00","publicationYear":"2009","noYear":false,"publicationType":{"id":18,"text":"Report"},"publicationSubtype":{"id":5,"text":"USGS Numbered Series"},"seriesTitle":{"id":330,"text":"Open-File Report","code":"OFR","onlineIssn":"2331-1258","printIssn":"0196-1497","active":true,"publicationSubtype":{"id":5}},"seriesNumber":"2009-1084","title":"Potentiometric Surface of the Upper Patapsco Aquifer in Southern Maryland, September 2007","docAbstract":"This report presents a map showing the potentiometric surface of the upper Patapsco aquifer in the Patapsco Formation of Early Cretaceous age in Southern Maryland during September 2007.

From this area, the potentiometric surface declined south towards well fields at Glen Burnie, Bryans Road, the Morgantown power plant, and the Chalk Point power plant. The measured ground-water levels were 81 feet below sea level at Glen Burnie, 47 feet below sea level southwest of Bryans Road, 27 feet below sea level at the Morgantown power plant, and 24 feet below sea level at the Chalk Point power plant.","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/ofr20091088","collaboration":"Prepared in cooperation with the Maryland Geological Survey (MGS) and the Power Plant Assessment Program, Maryland Department of Natural Resources","usgsCitation":"Curtin, S.E., Andreasen, D., and Staley, A., 2009, Potentiometric Surface of the Patuxent Aquifer in Southern Maryland, September 2007: U.S. Geological Survey Open-File Report 2009-1088, Sheet: 8.5 x 11 inches, https://doi.org/10.3133/ofr20091088.","productDescription":"Sheet: 8.5 x 11 inches","temporalStart":"2007-09-01","temporalEnd":"2007-09-30","costCenters":[{"id":41514,"text":"Maryland-Delaware-District of Columbia Water Science Center","active":true,"usgs":true}],"links":[{"id":12751,"rank":2,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/of/2009/1088/","linkFileType":{"id":5,"text":"html"}},{"id":195384,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"}],"geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -77.5,37.75 ], [ -77.5,39.583333333333336 ], [ -75.75,39.583333333333336 ], [ -75.75,37.75 ], [ -77.5,37.75 ] ] ] } } ] }","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4ad4e4b07f02db6831c6","contributors":{"authors":[{"text":"Curtin, Stephen E. securtin@usgs.gov","contributorId":3703,"corporation":false,"usgs":true,"family":"Curtin","given":"Stephen","email":"securtin@usgs.gov","middleInitial":"E.","affiliations":[{"id":374,"text":"Maryland Water Science Center","active":true,"usgs":true}],"preferred":true,"id":302654,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Andreasen, David C.","contributorId":59003,"corporation":false,"usgs":true,"family":"Andreasen","given":"David C.","affiliations":[],"preferred":false,"id":302656,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Staley, Andrew W.","contributorId":43319,"corporation":false,"usgs":true,"family":"Staley","given":"Andrew W.","affiliations":[],"preferred":false,"id":302655,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}} ,{"id":97599,"text":"ofr20091080 - 2009 - Potentiometric Surface of the Aquia Aquifer in Southern Maryland, September 2007","interactions":[],"lastModifiedDate":"2023-03-10T12:44:41.587349","indexId":"ofr20091080","displayToPublicDate":"2009-06-16T00:00:00","publicationYear":"2009","noYear":false,"publicationType":{"id":18,"text":"Report"},"publicationSubtype":{"id":5,"text":"USGS Numbered Series"},"seriesTitle":{"id":330,"text":"Open-File Report","code":"OFR","onlineIssn":"2331-1258","printIssn":"0196-1497","active":true,"publicationSubtype":{"id":5}},"seriesNumber":"2009-1080","title":"Potentiometric Surface of the Aquia Aquifer in Southern Maryland, September 2007","docAbstract":"This report presents a map showing the potentiometric surface of the Aquia aquifer in the Aquia Formation of Paleocene age in Southern Maryland during September 2007.

A user-friendly interface of simple buttons and menus guides the user through the major steps of shoreline change analysis. Components of the extension and user guide include (1) instruction on the proper way to define a reference baseline for measurements, (2) automated and manual generation of measurement transects and metadata based on user-specified parameters, and (3) output of calculated rates of shoreline change and other statistical information. DSAS computes shoreline rates of change using four different methods: (1) endpoint rate, (2) simple linear regression, (3) weighted linear regression, and (4) least median of squares. The standard error, correlation coefficient, and confidence interval are also computed for the simple and weighted linear-regression methods. The results of all rate calculations are output to a table that can be linked to the transect file by a common attribute field. DSAS is intended to facilitate the shoreline change-calculation process and to provide rate-of-change information and the statistical data necessary to establish the reliability of the calculated results. The software is also suitable for any generic application that calculates positional change over time, such as assessing rates of change of glacier limits in sequential aerial photos, river edge boundaries, land-cover changes, and so on.","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/ofr20081278","collaboration":"Prepared in cooperation with Innovate!

The hazards being evaluated include earthquakes, landslides, floods, tsunamis, wildfires, and coastal hazards.\r\n\r\nFor the Coastal Hazards Task of the Multi-Hazards Demonstration Project in Southern California, the USGS is leading the development of a modeling system for forecasting the impact of winter storms threatening the entire Southern California shoreline from Pt. Conception to the Mexican border. The modeling system, run in real-time or with prescribed scenarios, will incorporate atmospheric information (that is, wind and pressure fields) with a suite of state-of-the-art physical process models (that is, tide, surge, and wave) to enable detailed prediction of currents, wave height, wave runup, and total water levels. Additional research-grade predictions of coastal flooding, inundation, erosion, and cliff failure will also be performed. Initial model testing, performance evaluation, and product development will be focused on a severe winter-storm scenario developed in collaboration with the Winter Storm Working Group of the USGS Multi-Hazards Demonstration Project in Southern California. Additional offline model runs and products will include coastal-hazard hindcasts of selected historical winter storms, as well as additional severe winter-storm simulations based on statistical analyses of historical wave and water-level data. The coastal-hazards model design will also be appropriate for simulating the impact of storms under various sea level rise and climate-change scenarios. The operational capabilities of this modeling system are designed to provide emergency planners with the critical information they need to respond quickly and efficiently and to increase public safety and mitigate damage associated with powerful coastal storms. For instance, high resolution local models will predict detailed wave heights, breaking patterns, and current strengths for use in warning systems for harbor-mouth navigation and densely populated coastal regions where beach safety is threatened. The offline applications are intended to equip coastal managers with the information needed to manage and allocate their resources effectively to protect sections of coast that may be most vulnerable to future severe storms.","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/ofr20091073","usgsCitation":"Barnard, P., O’Reilly, B., van Ormondt, M., Elias, E., Ruggiero, P., Erikson, L., Hapke, C., Collins, B., Guza, R.T., Adams, P.N., and Thomas, J., 2009, The framework of a coastal hazards model: A tool for predicting the impact of severe storms (Version 1.0): U.S. Geological Survey Open-File Report 2009-1073, iv, 21 p., https://doi.org/10.3133/ofr20091073.","productDescription":"iv, 21 p.","onlineOnly":"Y","costCenters":[{"id":645,"text":"Western Coastal and Marine Geology","active":false,"usgs":true}],"links":[{"id":195861,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"},{"id":402650,"rank":3,"type":{"id":36,"text":"NGMDB Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_86720.htm","linkFileType":{"id":5,"text":"html"}},{"id":12723,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/of/2009/1073/","linkFileType":{"id":5,"text":"html"}}],"country":"United States","state":"California","geographicExtents":"{\n \"type\": \"FeatureCollection\",\n \"features\": [\n {\n \"type\": \"Feature\",\n \"properties\": {},\n \"geometry\": {\n \"type\": \"Polygon\",\n \"coordinates\": [\n [\n [\n -120.5914306640625,\n 32.722598604044066\n ],\n [\n -116.65283203124999,\n 32.722598604044066\n ],\n [\n -116.65283203124999,\n 34.66032236481892\n ],\n [\n -120.5914306640625,\n 34.66032236481892\n ],\n [\n -120.5914306640625,\n 32.722598604044066\n ]\n ]\n ]\n }\n }\n ]\n}","edition":"Version 1.0","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4ac9e4b07f02db67c761","contributors":{"authors":[{"text":"Barnard, Patrick L.","contributorId":54936,"corporation":false,"usgs":true,"family":"Barnard","given":"Patrick L.","affiliations":[],"preferred":false,"id":302553,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"O’Reilly, Bill","contributorId":11299,"corporation":false,"usgs":true,"family":"O’Reilly","given":"Bill","email":"","affiliations":[],"preferred":false,"id":302549,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"van Ormondt, Maarten","contributorId":50181,"corporation":false,"usgs":true,"family":"van Ormondt","given":"Maarten","affiliations":[],"preferred":false,"id":302551,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Elias, Edwin","contributorId":50615,"corporation":false,"usgs":true,"family":"Elias","given":"Edwin","affiliations":[],"preferred":false,"id":302552,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Ruggiero, Peter","contributorId":15709,"corporation":false,"usgs":false,"family":"Ruggiero","given":"Peter","affiliations":[{"id":6680,"text":"Oregon State University","active":true,"usgs":false}],"preferred":false,"id":302550,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Erikson, Li H.","contributorId":10880,"corporation":false,"usgs":true,"family":"Erikson","given":"Li H.","affiliations":[],"preferred":false,"id":302548,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Hapke, Cheryl","contributorId":89846,"corporation":false,"usgs":true,"family":"Hapke","given":"Cheryl","affiliations":[],"preferred":false,"id":302557,"contributorType":{"id":1,"text":"Authors"},"rank":7},{"text":"Collins, Brian D.","contributorId":71641,"corporation":false,"usgs":true,"family":"Collins","given":"Brian D.","affiliations":[],"preferred":false,"id":302555,"contributorType":{"id":1,"text":"Authors"},"rank":8},{"text":"Guza, Robert T.","contributorId":74095,"corporation":false,"usgs":true,"family":"Guza","given":"Robert","email":"","middleInitial":"T.","affiliations":[],"preferred":false,"id":302556,"contributorType":{"id":1,"text":"Authors"},"rank":9},{"text":"Adams, Peter N.","contributorId":64361,"corporation":false,"usgs":true,"family":"Adams","given":"Peter","email":"","middleInitial":"N.","affiliations":[],"preferred":false,"id":302554,"contributorType":{"id":1,"text":"Authors"},"rank":10},{"text":"Thomas, Julie","contributorId":107007,"corporation":false,"usgs":true,"family":"Thomas","given":"Julie","email":"","affiliations":[],"preferred":false,"id":302558,"contributorType":{"id":1,"text":"Authors"},"rank":11}]}} ,{"id":97581,"text":"ofr20091101 -

These hydrodynamically shaped discs are deployed at discrete time intervals from the Intervalometer and provide markers that delineate time intervals within the sediments that accumulate in the collection tube.\r\n\r\nThe timer and mechanical system are lodged in an air-filled, water-tight pressure housing that is vertically hung within the confines of a cone-shaped sediment trap. The instrumentation has been operationally pressure tested to an equivalent water depth of approximately 1 km.\r\n\r\nFlaws discovered during extensive laboratory and pressure testing resulted in the implementation of several mechanical modifications (such as a redesign of the rotor and the discs) that improved the operation of the rotor assembly as well as the release of discs through the end cap. These results also identified a preferred azimuth placement of the rotor disc relative to the drop hole of the end cap. \r\n\r\nIn the initial field trial, five sediment traps and coupled Intervalometers were attached to moored arrays and deployed at two sites off the coast of Southern California for approximately 8 months. Each of the instruments released 18 discs at the programmed 10 day intervals, except one unit, which experienced a malfunction after approximately 4 months. Most of the discs oriented in a near-horizontal position upon the surface of the sediment in the collection tubes. Sampling of the sediments for geochemical analyses was improved by these clearly defined markers, which indicated the changes in the flux and nature of sediments accumulated during the deployment period of each sediment trap.","language":"ENGLISH","publisher":"U.S. Geological Survey","doi":"10.3133/ofr20091101","usgsCitation":"Rendigs, R.R., Anderson, R.Y., Xu, J., Davis, R.E., and Bergeron, E., 2009, The Partition Intervalometer: A Programmable Underwater Timer for Marking Accumulated Sediment Profiles Collected in Anderson Sediment Traps: Development, Operation, Testing Procedures, and Field Results: U.S. Geological Survey Open-File Report 2009-1101, Available online only, https://doi.org/10.3133/ofr20091101.","productDescription":"Available online only","onlineOnly":"Y","additionalOnlineFiles":"Y","costCenters":[{"id":595,"text":"U.S. Geological Survey","active":false,"usgs":true}],"links":[{"id":196131,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"},{"id":12724,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/of/2009/1101/","linkFileType":{"id":5,"text":"html"}}],"geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -120.5,33 ], [ -120.5,35 ], [ -117.5,35 ], [ -117.5,33 ], [ -120.5,33 ] ] ] } } ] }","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4ac7e4b07f02db67ae67","contributors":{"authors":[{"text":"Rendigs, Richard R.","contributorId":56652,"corporation":false,"usgs":true,"family":"Rendigs","given":"Richard","email":"","middleInitial":"R.","affiliations":[{"id":678,"text":"Woods Hole Coastal and Marine Science Center","active":true,"usgs":true}],"preferred":false,"id":302562,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Anderson, Roger Y.","contributorId":19251,"corporation":false,"usgs":true,"family":"Anderson","given":"Roger","email":"","middleInitial":"Y.","affiliations":[],"preferred":false,"id":302561,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Xu, Jingping jpx@usgs.gov","contributorId":2574,"corporation":false,"usgs":true,"family":"Xu","given":"Jingping","email":"jpx@usgs.gov","affiliations":[{"id":520,"text":"Pacific Coastal and Marine Science Center","active":true,"usgs":true}],"preferred":true,"id":302559,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Davis, Raymond E.","contributorId":87648,"corporation":false,"usgs":true,"family":"Davis","given":"Raymond","email":"","middleInitial":"E.","affiliations":[],"preferred":false,"id":302563,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Bergeron, Emile M. ebergeron@usgs.gov","contributorId":3449,"corporation":false,"usgs":true,"family":"Bergeron","given":"Emile M.","email":"ebergeron@usgs.gov","affiliations":[{"id":678,"text":"Woods Hole Coastal and Marine Science Center","active":true,"usgs":true}],"preferred":false,"id":302560,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}} ,{"id":97577,"text":"ofr20091104 - 2009 - Analysis of Effects of 2003 and Full-Allocation Withdrawals in Critical Area 1, East-Central New Jersey","interactions":[],"lastModifiedDate":"2012-03-08T17:16:25","indexId":"ofr20091104","displayToPublicDate":"2009-06-06T00:00:00","publicationYear":"2009","noYear":false,"publicationType":{"id":18,"text":"Report"},"publicationSubtype":{"id":5,"text":"USGS Numbered Series"},"seriesTitle":{"id":330,"text":"Open-File Report","code":"OFR","onlineIssn":"2331-1258","printIssn":"0196-1497","active":true,"publicationSubtype":{"id":5}},"seriesNumber":"2009-1104","title":"Analysis of Effects of 2003 and Full-Allocation Withdrawals in Critical Area 1, East-Central New Jersey","docAbstract":"Critical Area 1 in east-central New Jersey was mandated in the early 1980s to address large drawdowns caused by increases in groundwater withdrawals. The aquifers involved include the Englishtown aquifer system, Wenonah-Mount Laurel aquifer, and the Upper and Middle Potomac-Raritan-Magothy aquifers. Groundwater levels recovered as a result of mandated cutbacks in withdrawals that began in the late 1980s. Subsequent increased demand for water has necessitated an analysis to determine the effects of full-allocation withdrawals, which supplements an optimization analysis done previously. A steady-state regional groundwater flow model is used to evaluate the effects of 2003 withdrawals and full-allocation withdrawals (7.3 million gallons per day greater than for 2003) on simulated water-levels. Simulation results indicate that the range of available withdrawals greater than full-allocation withdrawals is likely between 0 and 12 million gallons per day. The estimated range of available withdrawals is based on: (1) an examination of hydraulic-heads resulting from each of the two simulations, (2) an examination of differences in heads between these two simulations, (3) a comparison of simulated heads from each of the two simulations with the estimated location of salty groundwater, and (4) a comparison of simulated 2003 water levels to observed 2003 water levels. The results of the simulations also indicate that obtaining most of the available water would require varying the distribution of withdrawals and (or) relaxing the mandated hydrologic constraints used to protect the water supply.","language":"ENGLISH","publisher":"U.S. Geological Survey","doi":"10.3133/ofr20091104","collaboration":"Prepared in cooperation with the New Jersey Department of Environmental Protection","usgsCitation":"Spitz, F.J., 2009, Analysis of Effects of 2003 and Full-Allocation Withdrawals in Critical Area 1, East-Central New Jersey: U.S. Geological Survey Open-File Report 2009-1104, iv, 15 p., https://doi.org/10.3133/ofr20091104.","productDescription":"iv, 15 p.","temporalStart":"2003-01-01","temporalEnd":"2003-12-31","costCenters":[{"id":470,"text":"New Jersey Water Science Center","active":true,"usgs":true}],"links":[{"id":12720,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/of/2009/1104/","linkFileType":{"id":5,"text":"html"}},{"id":195806,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"}],"geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -75,39.5 ], [ -75,40.75 ], [ -73.75,40.75 ], [ -73.75,39.5 ], [ -75,39.5 ] ] ] } } ] }","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4ad0e4b07f02db680b80","contributors":{"authors":[{"text":"Spitz, Frederick J. 0000-0002-1391-2127 fspitz@usgs.gov","orcid":"https://orcid.org/0000-0002-1391-2127","contributorId":2777,"corporation":false,"usgs":true,"family":"Spitz","given":"Frederick","email":"fspitz@usgs.gov","middleInitial":"J.","affiliations":[],"preferred":true,"id":302542,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}} ,{"id":97575,"text":"ofr20091107 - 2009 - Fort Collins Science Center - Fiscal Year 2008 Science Accomplishments","interactions":[],"lastModifiedDate":"2012-02-02T00:14:28","indexId":"ofr20091107","displayToPublicDate":"2009-06-05T00:00:00","publicationYear":"2009","noYear":false,"publicationType":{"id":18,"text":"Report"},"publicationSubtype":{"id":5,"text":"USGS Numbered Series"},"seriesTitle":{"id":330,"text":"Open-File Report","code":"OFR","onlineIssn":"2331-1258","printIssn":"0196-1497","active":true,"publicationSubtype":{"id":5}},"seriesNumber":"2009-1107","title":"Fort Collins Science Center - Fiscal Year 2008 Science Accomplishments","docAbstract":"Public land and natural resource managers in the United States are confronted with increasingly complex decisions that have important ramifications for both ecological and human systems.

Dissolved nitrite plus nitrate had a different seasonal cycle and was below detection or at low concentration in summer. \r\n*Although total nitrogen and total phosphorus concentrations did not show large differences from upstream to downstream, filtered ammonia and orthophosphate concentrations increased in the downstream direction and particulate carbon and particulate nitrogen generally decreased in the downstream direction. \r\n*Large bacterial cells made up most of the bacteria biovolume, though cocci were the most numerous bacteria type. Cocci, with diameters of 0.1 to 0.2 micrometers, were smaller than the filter pore sizes used to separate dissolved from particulate matter. \r\n*Phytoplankton biovolumes were dominated by diatoms in spring and by the blue-green alga Aphanizomenon flos-aquae after mid-June. Another blue-green, Anabaena flos-aquae, was noted in samples from late May to late June. Phytoplankton biovolumes generally were highest at the upstream Link River and Railroad Bridge sites and decreased in the downstream direction. \r\n*Zooplankton densities were largest in late April. Populations were dominated by rotifers and copepods in early spring, and by rotifers and cladocerans in summer, with cladocerans most common at the most upstream site.","language":"ENGLISH","publisher":"U.S. Geological Survey","doi":"10.3133/ofr20091105","collaboration":"Prepared in cooperation with the Bureau of Reclamation","usgsCitation":"Sullivan, A.B., Deas, M., Asbill, J., Kirshtein, J.D., Butler, K.D., and Vaughn, J., 2009, Klamath River Water Quality Data from Link River Dam to Keno Dam, Oregon, 2008: U.S. Geological Survey Open-File Report 2009-1105, Report: vi, 25 p.; Appendixes (Zip), https://doi.org/10.3133/ofr20091105.","productDescription":"Report: vi, 25 p.; Appendixes (Zip)","additionalOnlineFiles":"Y","temporalStart":"2008-04-01","temporalEnd":"2008-11-30","costCenters":[{"id":518,"text":"Oregon Water Science Center","active":true,"usgs":true}],"links":[{"id":195998,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"},{"id":12719,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/of/2009/1105/","linkFileType":{"id":5,"text":"html"}}],"geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -122,42 ], [ -122,42.333333333333336 ], [ -121.66666666666667,42.333333333333336 ], [ -121.66666666666667,42 ], [ -122,42 ] ] ] } } ] }","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b32e4b07f02db6b47c2","contributors":{"authors":[{"text":"Sullivan, Annett B. 0000-0001-7783-3906 annett@usgs.gov","orcid":"https://orcid.org/0000-0001-7783-3906","contributorId":56317,"corporation":false,"usgs":true,"family":"Sullivan","given":"Annett","email":"annett@usgs.gov","middleInitial":"B.","affiliations":[],"preferred":false,"id":302539,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Deas, Michael L.","contributorId":98830,"corporation":false,"usgs":true,"family":"Deas","given":"Michael L.","affiliations":[],"preferred":false,"id":302541,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Asbill, Jessica","contributorId":79575,"corporation":false,"usgs":true,"family":"Asbill","given":"Jessica","affiliations":[],"preferred":false,"id":302540,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Kirshtein, Julie D.","contributorId":26033,"corporation":false,"usgs":true,"family":"Kirshtein","given":"Julie","email":"","middleInitial":"D.","affiliations":[],"preferred":false,"id":302537,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Butler, Kenna D. kebutler@usgs.gov","contributorId":3283,"corporation":false,"usgs":true,"family":"Butler","given":"Kenna","email":"kebutler@usgs.gov","middleInitial":"D.","affiliations":[{"id":5044,"text":"National Research Program - Central Branch","active":true,"usgs":true}],"preferred":false,"id":302536,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Vaughn, Jennifer","contributorId":33009,"corporation":false,"usgs":true,"family":"Vaughn","given":"Jennifer","email":"","affiliations":[],"preferred":false,"id":302538,"contributorType":{"id":1,"text":"Authors"},"rank":6}]}} ]}
