Remote sensing methods for estimating evaporative water losses by soil and vegetation (evapotranspiration, ET) over wide river stretches are needed to allocate water for agricultural and environmental needs. We used the Enhanced Vegetation Index (EVI) from MODIS sensors on the Terra satellite to scale ET over agricultural and riparian areas along the Lower Colorado River in the southwestern U.S., using a linear regression equation between ET of riparian plants and alfalfa measured on the ground, and meteorological and remote sensing data, with an error or uncertainty of about 20%. The algorithm was applied to irrigation districts and riparian areas from Lake Mead to the U.S./Mexico border. The results for agricultural crops were similar to results produced by crop coefficients developed for the irrigation districts along the river. However, riparian ET was only half as great as crop coefficient estimates set by expert opinion, equal to about 40% of reference crop evapotranspiration.

An important part of the delta ecosystem is the riparian corridor, which is supported by agricultural return flows and waste spills of water originating in the&nbsp;U.S.&nbsp;and Mexico. These flows may be curtailed in the future due to&nbsp;climate change&nbsp;and changing land use practices (out-of-basin water transfers, increased agricultural efficiency, and more optimal management of dams) in the U.S. and Mexico, and resource managers need to monitor the effects of their water management practices on these ecosystems. We developed ground-validated,&nbsp;remote sensing&nbsp;methods to monitor the vegetation status, habitat value, and water use of wetland and riparian ecosystems using multi-temporal, multi-resolution images. The integrated methodology allowed us to project species composition, leaf area index, fractional cover, habitat value, and&nbsp;evapotranspiration&nbsp;over seasons and years throughout the delta, in response to variable water flows from the U.S. to Mexico. Waste spills of water from the U.S. have regenerated native cottonwood and willow trees in the riparian corridor and created backwater and marsh areas that support birds and other wildlife. However, the main source of water supporting the&nbsp;riparian vegetation&nbsp;is the regional aquifer recharged by underflow from U.S. and Mexico&nbsp;irrigation districts. Native trees have a short half-life in the&nbsp;riparian zone&nbsp;due to human-set fires and harvesting for timber. Active management, monitoring, and restoration programs are needed to maintain the habitat value of this ecosystem for the future.</span></p>","language":"English","publisher":"Elsevier","doi":"10.1016/j.rse.2008.06.018","usgsCitation":"Nagler, P.L., Glenn, E., and Hinojosa-Huera, O., Synthesis of ground and remote sensing data for monitoring ecosystem functions in the Colorado River Delta, Mexico: Remote Sensing of Environment, v. 113, no. 7, p. 1473-1485, https://doi.org/10.1016/j.rse.2008.06.018.","productDescription":"13 p.","startPage":"1473","endPage":"1485","costCenters":[{"id":568,"text":"Southwest Biological Science Center","active":true,"usgs":true}],"links":[{"id":497645,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"Mexico","otherGeospatial":"Colorado River Delta","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -114.7360144715991,\n              32.519626708379434\n            ],\n            [\n              -115.38432903382771,\n              32.488742820889456\n            ],\n            [\n              -115.13525903251964,\n              31.663178387787312\n            ],\n            [\n              -114.51990961752253,\n              31.644472894515545\n            ],\n            [\n              -114.7360144715991,\n              32.519626708379434\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","volume":"113","issue":"7","noUsgsAuthors":false,"publicationDate":"2009-03-27","publicationStatus":"PW","contributors":{"authors":[{"text":"Nagler, Pamela L. 0000-0003-0674-103X pnagler@usgs.gov","orcid":"https://orcid.org/0000-0003-0674-103X","contributorId":1398,"corporation":false,"usgs":true,"family":"Nagler","given":"Pamela","email":"pnagler@usgs.gov","middleInitial":"L.","affiliations":[{"id":568,"text":"Southwest Biological Science Center","active":true,"usgs":true}],"preferred":true,"id":952561,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Glenn, Edward P.","contributorId":56542,"corporation":false,"usgs":false,"family":"Glenn","given":"Edward P.","affiliations":[{"id":13060,"text":"Department of Soil, Water and Environmental Science, University of Arizona","active":true,"usgs":false}],"preferred":false,"id":952562,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Hinojosa-Huera, Osvel","contributorId":339751,"corporation":false,"usgs":false,"family":"Hinojosa-Huera","given":"Osvel","email":"","affiliations":[{"id":24640,"text":"Pronatura Noroeste","active":true,"usgs":false}],"preferred":false,"id":952563,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

Local wave action not only drives circulation through processes such as longshore transport and rip currents, but also contributes significantly to the mixing of water quality constituents. In the present work, a wave model was used to calculate radiation shear stresses and dissipation due to wave action. The shear stresses and dissipation were incorporated into a hydrodynamic model to force circulation in the nearshore environment. The model was applied to a site in Santa Cruz, CA where site specific current data was available. The model reproduces the nearshore current structure observed in the region and was used to study the transport of dredge disposal plumes in the region which could have deleterious effects on local beaches.

Although many variations exist, most of them ratio the reflection of light in the red and NIR sections of the spectrum to separate the landscape into water, soil, and vegetation. Theoretical analyses and field studies have shown that VIs are near-linearly related to photosynthetically active radiation absorbed by a plant canopy, and therefore to light-dependent physiological processes, such as photosynthesis, occurring in the upper canopy. Practical studies have used time-series VIs to measure primary production and evapotranspiration, but these are limited in accuracy to that of the data used in ground truthing or calibrating the models used. VIs are also used to estimate a wide variety of other canopy attributes that are used in Soil-Vegetation-Atmosphere Transfer (SVAT), Surface Energy Balance (SEB), and Global Climate Models (GCM). These attributes include fractional vegetation cover, leaf area index, roughness lengths for turbulent transfer, emissivity and albedo. However, VIs often exhibit only moderate, non-linear relationships to these canopy attributes, compromising the accuracy of the models. We use case studies to illustrate the use and misuse of VIs, and argue for using VIs most simply as a measurement of canopy light absorption rather than as a surrogate for detailed features of canopy architecture. Used this way, VIs are compatible with “Big Leaf” SVAT and GCMs that assume that canopy carbon and moisture fluxes have the same relative response to the environment as any single leaf, simplifying the task of modeling complex landscapes.</span></p>","language":"English","publisher":"MDPI","doi":"10.3390/s8042136","usgsCitation":"Glenn, E.P., Huete, A.R., Nagler, P.L., and Nelson, S.G., Relationship between remotely-sensed vegetation indices, canopy attributes and plant physiological processes: What vegetation indices can and cannot tell us about the landscape: Sensors, v. 8, no. 4, p. 2136-2160, https://doi.org/10.3390/s8042136.","productDescription":"25 p.","startPage":"2136","endPage":"2160","costCenters":[{"id":568,"text":"Southwest Biological Science Center","active":true,"usgs":true}],"links":[{"id":498055,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.3390/s8042136","text":"Publisher Index Page"},{"id":497937,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Arizona","otherGeospatial":"Colorado River, Havasu National Wildlife Refuge","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -114.46320466185165,\n              34.705992498069406\n            ],\n            [\n              -114.398916590966,\n              34.73603912838132\n            ],\n            [\n              -114.53190465917093,\n              34.97188700395952\n            ],\n            [\n              -114.64409364561838,\n              34.905752361774034\n            ],\n            [\n              -114.54892208969932,\n              34.76089704626571\n            ],\n            [\n              -114.46320466185165,\n              34.705992498069406\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","volume":"8","issue":"4","noUsgsAuthors":false,"publicationDate":"2008-03-28","publicationStatus":"PW","contributors":{"authors":[{"text":"Glenn, Edward P.","contributorId":19289,"corporation":false,"usgs":true,"family":"Glenn","given":"Edward","email":"","middleInitial":"P.","affiliations":[],"preferred":false,"id":952873,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Huete, Alfredo R","contributorId":243589,"corporation":false,"usgs":false,"family":"Huete","given":"Alfredo","email":"","middleInitial":"R","affiliations":[{"id":48742,"text":"School of Life Sciences, Faculty of Science, University of Technology Sydney, Sydney, NSW 2007, Australia","active":true,"usgs":false}],"preferred":false,"id":952874,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Nagler, Pamela L. 0000-0003-0674-103X pnagler@usgs.gov","orcid":"https://orcid.org/0000-0003-0674-103X","contributorId":1398,"corporation":false,"usgs":true,"family":"Nagler","given":"Pamela","email":"pnagler@usgs.gov","middleInitial":"L.","affiliations":[{"id":568,"text":"Southwest Biological Science Center","active":true,"usgs":true}],"preferred":true,"id":952875,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Nelson, Stephen G.","contributorId":174719,"corporation":false,"usgs":false,"family":"Nelson","given":"Stephen","email":"","middleInitial":"G.","affiliations":[],"preferred":false,"id":952876,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

On the other hand, riparian corridors provide important wildlife habitat, especially for birds, and riparian vegetation is adapted to the natural variability in flows on these rivers. While environmental and flood control goals might appear to be at odds, we show that both goals can be accommodated in the Limitrophe Region (the shared border between the United States and Mexico) on the Lower Colorado River. In 1999, the International Boundary and Water Commission proposed a routine maintenance project to clear vegetation and create a pilot channel within the Limitrophe Region to improve flow capacity and delineate the border. In 2000, however, Minute 306 to the international water treaty was adopted, which calls for consideration of environmental effects of IBWC actions. We conducted vegetation and bird surveys within the Limitrophe and found that this river segment is unusually rich in native cottonwood and willow trees, marsh habitat, and resident and migratory birds compared to flow-regulated segments of river. A flood-frequency analysis showed that the existing levee system can easily contain a 100 year flood even if vegetation is not removed, and the existing braided channel system has greater carrying capacity than the proposed pilot channel.</span></p>","language":"English","publisher":"Springer","doi":"10.1007/s00267-007-9056-4","usgsCitation":"Glenn, E.P., Hucklebridge, K., Hinojosa-Huerta, O., Nagler, P.L., and Pitt, J., Reconciling environmental and flood control goals on an arid-zone river: Case study of the Limitrophe Region of the lower Colorado River in the United States and Mexico: Environmental Management, v. 41, p. 322-335, https://doi.org/10.1007/s00267-007-9056-4.","productDescription":"14 p.","startPage":"322","endPage":"335","costCenters":[{"id":568,"text":"Southwest Biological Science Center","active":true,"usgs":true}],"links":[{"id":497938,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"Mexico, United States","otherGeospatial":"lower Colorado River","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -113.84952634861096,\n              34.55176370207661\n            ],\n            [\n              -115.2034771735304,\n              34.55176370207661\n            ],\n            [\n              -115.2034771735304,\n              31.579861300988156\n            ],\n            [\n              -113.84952634861096,\n              31.579861300988156\n            ],\n            [\n              -113.84952634861096,\n              34.55176370207661\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","volume":"41","noUsgsAuthors":false,"publicationDate":"2008-01-01","publicationStatus":"PW","contributors":{"authors":[{"text":"Glenn, Edward P.","contributorId":19289,"corporation":false,"usgs":true,"family":"Glenn","given":"Edward","email":"","middleInitial":"P.","affiliations":[],"preferred":false,"id":952877,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Hucklebridge, Kate","contributorId":364563,"corporation":false,"usgs":false,"family":"Hucklebridge","given":"Kate","affiliations":[],"preferred":false,"id":952878,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Hinojosa-Huerta, Osvel","contributorId":195177,"corporation":false,"usgs":false,"family":"Hinojosa-Huerta","given":"Osvel","email":"","affiliations":[],"preferred":false,"id":952879,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Nagler, Pamela L. 0000-0003-0674-103X pnagler@usgs.gov","orcid":"https://orcid.org/0000-0003-0674-103X","contributorId":1398,"corporation":false,"usgs":true,"family":"Nagler","given":"Pamela","email":"pnagler@usgs.gov","middleInitial":"L.","affiliations":[{"id":568,"text":"Southwest Biological Science Center","active":true,"usgs":true}],"preferred":true,"id":952880,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Pitt, Jennifer","contributorId":255277,"corporation":false,"usgs":false,"family":"Pitt","given":"Jennifer","affiliations":[{"id":51507,"text":"Audubon","active":true,"usgs":false}],"preferred":false,"id":952881,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}}

Two cross-borehole flow tests were completed. Each test involved measurement and analysis of transient flow in a newly installed deep corehole with a long open interval during short-term pumping and recovery in an adjacent shallow well with a short open interval. The cross-borehole flow test in the mudstone identified a hydraulic connection through a dipping fractured bed between the pumped interval in the well and a flow zone at an intermediate depth in the corehole. The presence of a hydraulic connection between the pumped well and the corehole was not obvious because the water-level response in the corehole was dominated by a shallow zone of high transmissivity, which was hydraulically isolated from the pumped interval. In the sandstone, the cross-borehole flow test identified a hydraulic connection along dipping fractured beds as well as a connection to a deep high-angle fracture that cuts across bedding. These results suggest that application of cross-borehole flow tests at other contaminated fractured-bedrock sites could provide insights into hydraulic connections useful the design and implementation of monitoring and remediation programs. </p>","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"Symposium on the Application of Geophysics to Engineering and Environmental

The prerequisite for an applicable model is that it should perform at an acceptable level of accuracy and uncertainties should be documented. In this study, we validated the gross primary productivity (GPP) data from a piecewise regression (PWR) model and the MODIS GPP model at five grassland flux towers in the Northern Great Plains. The results showed a good agreement of GPP values (agreement coefficient <i>d</i> = 0.88–0.98) among PWR, MODIS, and tower measurements at Fort Peck, Mandan, and Cheyenne sites; but MODIS GPP did not agree well (<i>d</i> = 0.62–0.79) with tower measurements at Miles City and Lethbridge sites. Additionally, we compared PWR GPP and MODIS GPP for grasslands in the entire study area. We found that the PWR GPP was lower than or similar to the MODIS GPP in the east and higher in the west and south. We explored possible factors that may cause the GPP difference in spatial distribution between the two models. </p>","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"Global priorities in land remote sensing","largerWorkSubtype":{"id":12,"text":"Conference publication"},"conferenceTitle":"William T.

Although the shield is clearly composite in nature, a large part of its interior has been represented by a single Precambrian block, termed the Mawson block, that includes the Archean-Mesoproterozoic Gawler and Curnamona cratons of Australia. In Australia, the Mawson block is bounded on the east by Neoproterozoic sedimentary rocks and the superimposed early Paleozoic Delamerian Orogen, marked by curvilinear belts of arc plutons, and on the west by the unexposed Coompana block and Mesoproterozoic Albany-Fraser mobile belt. In Antarctica, these crustal elements are inferred to extend across Wilkes Land and south to the Miller Range region. Aero- and satellite magnetic data provide a means to see through the ice, helping to elucidate the broad composition of the shield. Rocks of the Mawson block in Australia produce distinctive magnetic anomalies; Paleoproterozoic granites and Meso- to Neoproterozoic mafic igneous rocks are associated with high-amplitude, broad-wavelength positive aero- and satellite-magnetic anomalies. The same types of magnetic anomalies can be traced to ice-covered Wilkes Land, Antarctica, and are interpreted to signify similar rocks. However, the diagnostic satellite magnetic high ends ∼800 km south of the Antarctic coast, suggesting that the Mawson block is smaller than first proposed and that the remaining East Antarctic shield is composed of several Precambrian crustal blocks of largely undetermined composition and age. Nonetheless, the coincident eastern borders of these magnetic highs and high seismic-velocity anomalies characteristic of the Precambrian shield, together define the edge of thick cratonic lithosphere. East of this boundary, magnetic lows are explained by magnetite-poor upper Neoproterozoic and lower Paleozoic sedimentary rocks, and their metamorphic equivalents, which crop out discontinuously along the Ross margin of Antarctica and in eastern Australia. These rocks are inferred to overlie a Neoproterozoic rift margin, which transects older basement provinces. The coincidence of this cratonic rift boundary with the western limit of Paleozoic and Jurassic magmatism suggests that, although tectonically modified by younger events, the composite Antarctic-Australian shield comprised thick lithosphere that was not penetrated by Paleozoic and younger convergent-margin magmas.</span></p>","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"Antarctica: Contributions to global earth sciences","largerWorkSubtype":{"id":15,"text":"Monograph"},"language":"English","publisher":"Springer","doi":"10.1007/3-540-32934-X_20","usgsCitation":"Finn, C.A., Goodge, J.W., Damaske, D., and Fanning, C.M., Scouting craton’s edge in Paleo-Pacific Gondwana, chap. 4.1 <i>of</i> Antarctica: Contributions to global earth sciences, p. 165-173, https://doi.org/10.1007/3-540-32934-X_20.","productDescription":"9 p.","startPage":"165","endPage":"173","costCenters":[],"links":[{"id":420584,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"otherGeospatial":"Antarctica, Gondwana","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              106.88469524334846,\n              -57.49514229065598\n            ],\n            [\n              106.88469524334846,\n              -78.93509637484914\n            ],\n            [\n              164.3416785133088,\n              -78.93509637484914\n            ],\n            [\n              164.3416785133088,\n              -57.49514229065598\n            ],\n            [\n              106.88469524334846,\n              -57.49514229065598\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","contributors":{"editors":[{"text":"Futterer, Dieter Karl","contributorId":279857,"corporation":false,"usgs":false,"family":"Futterer","given":"Dieter","email":"","middleInitial":"Karl","affiliations":[],"preferred":false,"id":882257,"contributorType":{"id":2,"text":"Editors"},"rank":1},{"text":"Kleinschmidt, Georg","contributorId":26968,"corporation":false,"usgs":true,"family":"Kleinschmidt","given":"Georg","email":"","affiliations":[],"preferred":false,"id":882258,"contributorType":{"id":2,"text":"Editors"},"rank":2},{"text":"Miller, Hubert","contributorId":328909,"corporation":false,"usgs":false,"family":"Miller","given":"Hubert","email":"","affiliations":[],"preferred":false,"id":882259,"contributorType":{"id":2,"text":"Editors"},"rank":3},{"text":"Tessensohn, Franz","contributorId":27196,"corporation":false,"usgs":true,"family":"Tessensohn","given":"Franz","email":"","affiliations":[],"preferred":false,"id":882260,"contributorType":{"id":2,"text":"Editors"},"rank":4}],"authors":[{"text":"Finn, Carol A. 0000-0002-6178-0405 cfinn@usgs.gov","orcid":"https://orcid.org/0000-0002-6178-0405","contributorId":1326,"corporation":false,"usgs":true,"family":"Finn","given":"Carol","email":"cfinn@usgs.gov","middleInitial":"A.","affiliations":[{"id":211,"text":"Crustal Geophysics and Geochemistry Science Center","active":true,"usgs":true}],"preferred":true,"id":882253,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Goodge, John W.","contributorId":20414,"corporation":false,"usgs":true,"family":"Goodge","given":"John","email":"","middleInitial":"W.","affiliations":[],"preferred":false,"id":882254,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Damaske, Detlef","contributorId":77384,"corporation":false,"usgs":true,"family":"Damaske","given":"Detlef","email":"","affiliations":[],"preferred":false,"id":882255,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Fanning, C.

To better match the scale of data with that of the model, we propose a set of principles for the development of stochastic modeling systems based on linkage of deterministic models with GIS data. For modeling purposes, a region is usually rasterized into cells and the environmental conditions of those cells are specified by ranges or classes using GIS data layers. It is not necessary to simulate each and every GIS cell in the study area because many cells may have similar environmental conditions and can be grouped together to form cohorts. We define a cohort as the assembly of the cells sharing a unique combination of environmental conditions within the study region. Multiple model simulations can be performed for any given cohort. For each simulation, some of the parameter values can be randomly generated within the specified environmental conditions of the cohort according to a certain statistical distribution which, in turn, can be specified by GIS data layers. By this method the variance and covariance of environmental variables in space and time are integrated into the simulation processes with these modeling systems to make full use of the available data and to assess the uncertainties of the simulated results. An integrated simulation system between CENTURY model and GIS was developed to demonstrate the value of the concepts imbedded in stochastic simulation systems for large area studies.</p>","conferenceTitle":"4th International Conference on Integrating GIS and Environmental Modeling (GIS/EM4)","conferenceDate":"September 2-8, 2000","conferenceLocation":"Banff, Alberta, Canada","language":"English","publisher":"University of Colorado, Cooperative Institute for Research in Environmental Sciences","usgsCitation":"Liu, S., Reiners, W.A., Gerow, K.G., Schimel, D.S., and Keller, M., Development of stochastic modeling systems using deterministic models and GIS: Principles and a case study in the Atlantic Zone of Costa Rica, 4th International Conference on Integrating GIS and Environmental Modeling (GIS/EM4), Banff, Alberta, Canada, September 2-8, 2000, 9 p.","productDescription":"9 p.","costCenters":[{"id":222,"text":"Earth Resources Observation and Science (EROS) Center","active":true,"usgs":true}],"links":[{"id":481935,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"Costa Rica","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -82.6133520275848,\n              9.499325548625436\n            ],\n            [\n              -82.44230009071387,\n              9.73121764978167\n            ],\n            [\n              -83.54701051633626,\n              11.16801392273345\n            ],\n            [\n              -83.68242663302513,\n              10.951175271798036\n            ],\n            [\n              -83.66104514091643,\n              10.78319089811086\n            ],\n            [\n              -84.16707378749192,\n              10.566072375621317\n            ],\n            [\n              -83.7038081251345,\n              9.604750752776496\n            ],\n            [\n              -82.88418426096321,\n              9.506354909569495\n            ],\n            [\n              -82.6133520275848,\n              9.499325548625436\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","contributors":{"authors":[{"text":"Liu, Shuguang 0000-0002-6027-3479 sliu@usgs.gov","orcid":"https://orcid.org/0000-0002-6027-3479","contributorId":147403,"corporation":false,"usgs":true,"family":"Liu","given":"Shuguang","email":"sliu@usgs.gov","affiliations":[{"id":223,"text":"Earth Resources Observation and Science (EROS) Center (Geography)","active":false,"usgs":true}],"preferred":true,"id":927046,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Reiners, William A.","contributorId":147117,"corporation":false,"usgs":false,"family":"Reiners","given":"William","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":927047,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Gerow, Kenneth G.","contributorId":49672,"corporation":false,"usgs":true,"family":"Gerow","given":"Kenneth","email":"","middleInitial":"G.","affiliations":[],"preferred":false,"id":927048,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Schimel, David S","contributorId":267312,"corporation":false,"usgs":false,"family":"Schimel","given":"David","email":"","middleInitial":"S","affiliations":[{"id":55473,"text":"Jep Propulsion Laboratory","active":true,"usgs":false}],"preferred":false,"id":927049,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Keller, Michael","contributorId":42681,"corporation":false,"usgs":true,"family":"Keller","given":"Michael","email":"","affiliations":[],"preferred":false,"id":927050,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}}

The&nbsp;</span><span class=\"ScopusTermHighlight\">diagnosis</span><span>&nbsp;was based on pathologic lesions and confirmed by virus isolation. Control measures included quarantine, attempts to reduce virus contamination of the area, dispersal of waterfowl, and monitoring of wild waterfowl populations for mortality. The epizootic resulted in documented mortality of 18% and estimated mortality of 26% of the waterfowl at risk. Prompt implementation of control measures might have limited mortality to approximately 8%. Losses during the epizootic were equivalent to 0.12% of the annual mortality in the North American 1996 fall population of 80,000,000 wild ducks. The most likely sources of the infection were free-flying wild mallard or American black duck (Anas rubripes) carriers from the upper midwestern or northeastern United States. Duck plague serum neutralization antibodies were demonstrated in 31% of 395 apparently healthy mallards sampled prior to dispersal of the flock at Lake Andes, suggesting that tens of thousands of potential duck plague carriers entered the wild waterfowl populations of all four major flyways. Consequently, the absence of major epizootics of duck plague in wild waterfowl in the subsequent two decades is evidence that substantial numbers of duck plague carriers can occur in wild waterfowl populations without resulting in epizootic mortalities. The failure to isolate duck plague virus from apparently healthy mallards sampled during the epizootic raises questions concerning the validity of conclusions regarding the status of duck plague in wild waterfowl based upon negative results of random surveys conducted in the absence of epizootics. © Wildlife Disease Association 1997.</span></p>","language":"English","doi":"10.7589/0090-3558-33.4.681","issn":"00903558","usgsCitation":"Pearson, G.L., and Cassidy, D.R., Perspectives on the diagnosis, epizootiology, and control of the 1973 duck plague epizootic in wild waterfowl at Lake Andes, South Dakota: Journal of Wildlife Diseases, v. 33 , no. 4, p. 681-705, https://doi.org/10.7589/0090-3558-33.4.681.","productDescription":"25 p.

The texture consists of multiple layers of euhedral, prismatic quartz crystals (Type I) that have grown on subplanar aplite substrates. The layers are separated by porphyritic aplite containing equant phenocrysts of quartz (Type II), which resemble quartz typical of volcanic rocks and porphyry intrusions. At Logtung, Type I quartz within comb layers is zoned with respect to a number of trace elements, including Al and K. Concentrations of these elements as well as Mn, Ti, Ge, Rb and H are anomalous and much higher than found in Type II quartz from Logtung or in igneous quartz reported elsewhere. The two populations appear to have formed under different conditions. The Type II quartz phenocrysts almost certainly grew from a high-silica melt between 600 and 800°C (as β-quartz); in contrast, the morphology of Type I quartz is consistent with precipitation from a hydrothermal solution, possibly as α-quartz grown below 600°C. The bulk compositions of comb-layered rocks, as well as the aplite interlayers, are consistent with the hypothesis that these textures did not precipitate solely from a crystallising silicate melt. Instead, Type I quartz may have grown from pockets of exsolved magmatic fluid located between the magma and its crystallised border. The Type II quartz represents pre-existing phenocrysts in the underlying magma; this magma was quenched to aplite during fracturing/degassing events. Renewed and repeated formation and disruption of the pockets of exsolved aqueous fluid accounts for the rhythmic banding of the rocks.</span></p>","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"The Third Hutton symposium on the origin of granites and related rocks","largerWorkSubtype":{"id":15,"text":"Monograph"},"language":"English","publisherLocation":"1996","doi":"10.1130/0-8137-2315-9.291","usgsCitation":"Lowenstern, J.B., and Sinclair, W.D., Exsolved magmatic fluid and its role in the formation of comb-layered quartz at the Cretaceous Logtung W-Mo deposit, Yukon Territory, Canada, chap. <i>of</i> The Third Hutton symposium on the origin of granites and related rocks, v. 315, p. 291-303, https://doi.org/10.1130/0-8137-2315-9.291.","productDescription":"13 p.","startPage":"291","endPage":"303","costCenters":[{"id":617,"text":"Volcano Science Center","active":true,"usgs":true}],"links":[{"id":419057,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"Canada","state":"Yukon Territory","otherGeospatial":"Logtung","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -131.918034408077,\n              60.00963320120135\n            ],\n            [\n              -131.9420601623024,\n              60.00963320120135\n            ],\n            [\n              -131.9420601623024,\n              60.000111867680914\n            ],\n            [\n              -131.918034408077,\n              60.000111867680914\n            ],\n            [\n              -131.918034408077,\n              60.00963320120135\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","volume":"315","noUsgsAuthors":false,"publicationStatus":"PW","contributors":{"authors":[{"text":"Lowenstern, Jacob B. 0000-0003-0464-7779 jlwnstrn@usgs.gov","orcid":"https://orcid.org/0000-0003-0464-7779","contributorId":2755,"corporation":false,"usgs":true,"family":"Lowenstern","given":"Jacob","email":"jlwnstrn@usgs.gov","middleInitial":"B.","affiliations":[{"id":617,"text":"Volcano Science Center","active":true,"usgs":true}],"preferred":true,"id":878174,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Sinclair, W.

The distances measured (with corresponding standard deviation) range from 8.4 km (3.4 mm) to 38 km (8.2 mm). The data are displayed as plots of measured distance as a function of time. Linear fits in such plots furnish a satisfactory representation of the data. That is, the scatter of the data about the linear fits is within the range expected for the estimated standard deviations in measurement. However, there are coherent low‐amplitude (within the observational error) fluctuations apparent in some of the measured distances. Those fluctuations need not be tectonic effects but rather may be either random patterns or artifacts introduced by systematic drift in instrument calibration or wander of the geodetic monuments. We conclude that the measurements are consistent with steady deformation of the arrays over the 1980–1991 interval, and we find no convincing evidence in the data for fluctuations in the rate of deformation.</span></p>","language":"English","publisher":"American Geophysical Union","doi":"10.1029/95JB00611","usgsCitation":"Savage, J.C., and Lisowski, M., Geodetic monitoring of the southern San Andreas Fault, California, 1980-1991: Journal of Geophysical Research, v. 100, no.
