We developed a record of Holocene vegetation and climate change from 55 14C-dated woodrat middens at two low-elevation sites (1275 to 1590 m, currently vegetated by Juniperus osteosperma woodlands, in the northern Bighorn Basin. Macrofossil and pollen analyses show that the early Holocene was cooler than today, with warming and drying in the middle Holocene. During the Holocene, boreal (Juniperus communis, J. horizontalis) and montane species (J. scopulorum) were replaced by a Great Basin species (J. osteosperma). J. osteosperma colonized the east side of the Pryor Mountains 4700 14C yr B.P. Downward movement of lower treeline indicates wetter conditions between 4400 and 2700 14C yr B.P. Increased aridity after 2700 14C yr B.P. initiated expansion of J. osteosperma from the east to west side of the Pryor Mountains. ?? 2002 University of Washington.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Quaternary Research","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1006/qres.2002.2342","issn":"00335894","usgsCitation":"Lyford, M., Betancourt, J., and Jackson, S., 2002, Holocene vegetation and climate history of the northern Bighorn Basin, southern Montana: Quaternary Research, v. 58, no. 2, p. 171-181, https://doi.org/10.1006/qres.2002.2342.","startPage":"171","endPage":"181","numberOfPages":"11","costCenters":[],"links":[{"id":207016,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1006/qres.2002.2342"},{"id":231549,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"58","issue":"2","noUsgsAuthors":false,"publicationDate":"2017-01-20","publicationStatus":"PW","scienceBaseUri":"505a31f9e4b0c8380cd5e3f1","contributors":{"authors":[{"text":"Lyford, M.E.","contributorId":33883,"corporation":false,"usgs":true,"family":"Lyford","given":"M.E.","email":"","affiliations":[],"preferred":false,"id":401255,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Betancourt, J.L. 0000-0002-7165-0743","orcid":"https://orcid.org/0000-0002-7165-0743","contributorId":87505,"corporation":false,"usgs":true,"family":"Betancourt","given":"J.L.","affiliations":[{"id":595,"text":"U.S. Geological Survey","active":false,"usgs":true}],"preferred":false,"id":401256,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Jackson, S.T.","contributorId":90072,"corporation":false,"usgs":true,"family":"Jackson","given":"S.T.","email":"","affiliations":[],"preferred":false,"id":401257,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

Bighead carp subsequently escaped aquaculture facilities in the early 1980's and dispersed into the Mississippi and Missouri rivers. The first documentation of bighead carp reproduction in the Mississippi River system was in 1989. The population has increased in the Missouri River as is evident in their increased proportion in the commercial harvest since 1990. The effect of this exotic planktivore on native ecosystems of the U.S. has not been examined. Basic biological data on bighead carp Hypophthalmichthys nobilis in the Missouri River are needed to predict potential ecological problems and provide a foundation for manipulative studies. The objectives of this study were to assess age, growth, and gonadal characteristics of bighead carp in the Missouri River. Adult bighead carp in our sample varied from age 3 to age 7 and length varied from 475 to 1050 mm. There was a large variation in length at age, and overall bighead carp exhibited fast growth. For example, mean back-calculated length at age 3 was 556 mm. The sample was dominated by bighead carp from the 1994 year class. There was no difference in gonad development (i.e., gonadal somatic index, egg diameter) between winter and spring samples. Length of male bighead carp and GSI were not significantly correlated; however, females exhibited a positive linear relationship between length and GSI. In each ovary, egg diameter frequencies exhibited a bimodal distribution, indicating protracted spawning. Mean fecundity was 226 213, with a maximum fecundity of 769 964. Bighead carp in the Missouri River have similar life history characteristics to Asian and European populations. They have become well established in the Missouri River and it is likely that dispersal and population density will increase.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Environmental Biology of Fishes","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1023/A:1016144529734","issn":"03781909","usgsCitation":"Schrank, S., and Guy, C., 2002, Age, growth, and gonadal characteristics of adult bighead carp, Hypophthalmichthys nobilis, in the lower Missouri River: Environmental Biology of Fishes, v. 64, no. 4, p. 443-450, https://doi.org/10.1023/A:1016144529734.","startPage":"443","endPage":"450","numberOfPages":"8","costCenters":[],"links":[{"id":207046,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1023/A:1016144529734"},{"id":231617,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"64","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059e8f7e4b0c8380cd47ff4","contributors":{"authors":[{"text":"Schrank, S.J.","contributorId":76499,"corporation":false,"usgs":true,"family":"Schrank","given":"S.J.","email":"","affiliations":[],"preferred":false,"id":401243,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Guy, C.S.","contributorId":59160,"corporation":false,"usgs":true,"family":"Guy","given":"C.S.","email":"","affiliations":[],"preferred":false,"id":401242,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

Mine drainage sediments were collected from sites in the Anthracite Region of eastern Pennsylvania, representing acid to near neutral pH. Sediments occurring in acidic waters contained primarily schwertmannite and goethite while near neutral waters produced ferrihydrite. The minerals comprising the sediments occurring at each pH mode were spectrally separable. Spectral angle difference mapping was used to correlate sediment color with stream water pH (r2=0.76). Band-center and band-depth analysis of spectral absorption features were also used to discriminate ferrihydrite and goethite and/or schwertmannite by analyzing the 4T1??? 6A1 crystal field transition (900-1000 nm). The presence of these minerals accurately predicted stream water pH (r2=0.87) and provided a qualitative estimate of dissolved SO4 concentrations. Spectral analysis results were used to analyze airborne digital multispectral video (DMSV) imagery for several sites in the region. The high spatial resolution of the DMSV sensor allowed for precise mapping of the mine drainage sediments. The results from this study indicate that airborne and space-borne imaging spectrometers may be used to accurately classify streams impacted by acid vs. neutral-to-alkaline mine drainage after appropriate spectral libraries are developed.","language":"English","doi":"10.1016/S0883-2927(02)00019-7","issn":"08832927","usgsCitation":"Williams, D., Bigham, J., Cravotta, C., Traina, S., Anderson, J., and Lyon, J., 2002, Assessing mine drainage pH from the color and spectral reflectance of chemical precipitates: Applied Geochemistry, v. 17, no. 10, p. 1273-1286, https://doi.org/10.1016/S0883-2927(02)00019-7.","productDescription":"14","startPage":"1273","endPage":"1286","costCenters":[{"id":532,"text":"Pennsylvania Water Science Center","active":true,"usgs":true}],"links":[{"id":232085,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States ","state":"Pennsylvania","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -77.552490234375,\n              40.03182061333687\n            ],\n            [\n              -75.04486083984375,\n              40.03182061333687\n            ],\n            [\n              -75.04486083984375,\n              41.36238012945531\n            ],\n            [\n              -77.552490234375,\n              41.36238012945531\n            ],\n            [\n              -77.552490234375,\n              40.03182061333687\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"17","issue":"10","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059eddbe4b0c8380cd49a62","contributors":{"authors":[{"text":"Williams, D.J.","contributorId":15790,"corporation":false,"usgs":true,"family":"Williams","given":"D.J.","email":"","affiliations":[],"preferred":false,"id":401201,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Bigham, J.M.","contributorId":28403,"corporation":false,"usgs":true,"family":"Bigham","given":"J.M.","email":"","affiliations":[],"preferred":false,"id":401203,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Cravotta, C.A.

A minimum of 144 aquatic NIS have been recorded in the Lake Erie basin including several species [e.g., Eurasian watermilfoil (<i>Myriophyllum spicatum</i>); zebra mussel (<i>Dreissena polymorpha</i>); quagga mussel (Dreissena bugensis); an amphipod (Echinogammarus ischnus); round goby (Neogobius melanostomus); and sea lamprey (<i>Petromyzon marinus</i>)] that have had discernible impacts on the lake's ecology. NIS pose threats to the Lake Erie ecosystem for a variety of reasons including their ability to proliferate quickly, compete with native species, and transfer contaminants (e.g., PCBs) and disease through the food web. Six of the 14 beneficial use impairments listed in Annex 2 of the Great Lakes Water Quality Agreement are impaired in Lake Erie, in part as a result of the introduction of NIS. The Lake Erie Lakewide Management Plan (LaMP) has adopted an ecosystem approach to restore beneficial use impairments in the lake. Furthermore, a research consortium, known as the Lake Erie Millennium Network, is working alongside the LaMP, to address research problems regarding NIS, the loss of habitat, and the role of contaminants in the Lake Erie ecosystem.</p>","largerWorkType":{"id":24,"text":"Conference Paper"},"largerWorkTitle":"Proceedings of the 11th International Conference on Aquatic Invasive Species","largerWorkSubtype":{"id":19,"text":"Conference Paper"},"conferenceTitle":"11th International Conference on Aquatic Invasive Species","conferenceDate":"February 25-28, 2002","conferenceLocation":"Alexandria, VA","language":"English","publisher":"The Professional Edge","usgsCitation":"Austen, M.J., Ciborowski, J.J., Corkum, L.D., Johnson, T.B., MacIsaac, H.J., Metcalfe-Smith, J.L., Schloesser, D.W., and George, S.E., 2002, Impacts of aquatic nonindigenous invasive species on the Lake Erie ecosystem, <i>in</i> Proceedings of the 11th International Conference on Aquatic Invasive Species, Alexandria, VA, February 25-28, 2002, p. 117-130.","productDescription":"14 p.","startPage":"117","endPage":"130","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[{"id":324,"text":"Great Lakes Science Center","active":true,"usgs":true}],"links":[{"id":321760,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"57481e36e4b07e28b664dbcb","contributors":{"authors":[{"text":"Austen, Madeline J.W.","contributorId":169652,"corporation":false,"usgs":false,"family":"Austen","given":"Madeline","email":"","middleInitial":"J.W.","affiliations":[],"preferred":false,"id":630532,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Ciborowski, Jan J.H.","contributorId":107240,"corporation":false,"usgs":true,"family":"Ciborowski","given":"Jan","email":"","middleInitial":"J.H.","affiliations":[],"preferred":false,"id":630533,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Corkum, Lynda D.","contributorId":97866,"corporation":false,"usgs":true,"family":"Corkum","given":"Lynda","email":"","middleInitial":"D.","affiliations":[],"preferred":false,"id":630534,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Johnson, Tim B.","contributorId":127336,"corporation":false,"usgs":false,"family":"Johnson","given":"Tim","email":"","middleInitial":"B.","affiliations":[{"id":6780,"text":"Ontario Ministry of Natural Resources","active":true,"usgs":false}],"preferred":false,"id":630535,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"MacIsaac, Hugh J.","contributorId":169653,"corporation":false,"usgs":false,"family":"MacIsaac","given":"Hugh","email":"","middleInitial":"J.","affiliations":[],"preferred":false,"id":630536,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Metcalfe-Smith, Janice L.","contributorId":82267,"corporation":false,"usgs":true,"family":"Metcalfe-Smith","given":"Janice","email":"","middleInitial":"L.","affiliations":[],"preferred":false,"id":630537,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Schloesser, Donald W. dschloesser@usgs.gov","contributorId":3579,"corporation":false,"usgs":true,"family":"Schloesser","given":"Donald","email":"dschloesser@usgs.gov","middleInitial":"W.","affiliations":[{"id":324,"text":"Great Lakes Science Center","active":true,"usgs":true}],"preferred":true,"id":630538,"contributorType":{"id":1,"text":"Authors"},"rank":7},{"text":"George, Sandra E.","contributorId":169654,"corporation":false,"usgs":false,"family":"George","given":"Sandra","email":"","middleInitial":"E.","affiliations":[],"preferred":false,"id":630539,"contributorType":{"id":1,"text":"Authors"},"rank":8}]}}

In this paper, we investigate the modelling of groundwater problems using a particular adaptive mesh method called the moving mesh partial differential equation approach. With this approach, the mesh is dynamically relocated through a partial differential equation to capture the evolving sharp fronts with a relatively small number of grid points. The mesh movement and physical system modelling are realized by solving the mesh movement and physical partial differential equations alternately. The method is applied to the modelling of a range of groundwater problems, including advection dominated chemical transport and reaction, non-linear infiltration in soil, and the coupling of density dependent flow and transport. Numerical results demonstrate that sharp moving fronts can be accurately and efficiently captured by the moving mesh approach. Also addressed are important implementation strategies, e.g. the construction of the monitor function based on the interpolation error, control of mesh concentration, and two-layer mesh movement.

The WB model includes the concepts of climatic water supply and climatic water demand, seasonality in climatic water supply and demand, and soil-moisture storage. Exhaustive search techniques were employed to determine the optimal set of precipitation and temperature stations, and the optimal set of WB model parameters to use for each basin. It was found that the WB model worked best for basins with: (1) a mean elevation less than 450 meters or greater than 2000 meters, and/or (2) monthly runoff that is greater than 5 millimeters (mm) more than 80 percent of the time. In a separate analysis, a multiple linear regression (MLR) was computed using the adjusted R-square values obtained by comparing measured and estimated monthly runoff of the original 44 river basins as the dependent variable, and combinations of various independent variables [streamflow gauge latitude, longitude, and elevation; basin area, the long-term mean and standard deviation of annual precipitation; temperature and runoff; and low-flow statistics (i.e., the percentage of months with monthly runoff that is less than 5 mm)]. Results from the MLR study showed that the reliability of a WB model for application in a specific region can be estimated from mean basin elevation and the percentage of months with gauged runoff less than 5 mm. The MLR equations were subsequently used to estimate adjusted R-square values for 1,646 gauging stations across the conterminous U.S. Results of this study indicate that WB models can be used reliably to estimate monthly runoff in the eastern U.S., mountainous areas of the western U.S., and the Pacific Northwest. Applications of monthly WB models in the central U.S. can lead to uncertain estimates of runoff.</span></p>","language":"English","publisher":"Wiley","doi":"10.1111/j.1752-1688.2002.tb01001.x","usgsCitation":"Hay, L.E., and McCabe, G.J., 2002, Spatial variability in water-balance model

At the Land Processes Distributed Active Archive Center (LP DAAC), located at the USGS EROS Data Center, the EOS Data and Information System (EOSDIS) is required to support heritage missions as well as Landsat 7, Terra, and Aqua. The original system concept of the early 1990'S changed as each community had its say - first the managers, then engineers, scientists, developers, operators, and then finally the general public. The systems at the LP DAAC - particularly the largest single system, the EOSDIS Core System (ECS) - are changing as experience accumulates, technology changes, and each user group gains influence. The LP DAAC has adapted as contingencies were planned for, requirements and therefore plans were modified, and expectations changed faster than requirements could hope to be satisfied. Although not responsible for Quality Assurance of the science data, the LP DAAC works to ensure the data are accessible and useable by influencing systems, capabilities, and data formats where possible, and providing tools and user support as necessary. While supporting multiple missions and instruments, the LP DAAC also works with and learns from multiple management and oversight groups as they review mission requirements, system capabilities, and the overall operation of the LP DAAC. Stakeholders, including the Land Science community, are consulted regularly to ensure that the LP DAAC remains cognizant and responsive to the evolving needs of the user community. Today, the systems do not look or function as originally planned, but they do work, and they allow customers to search and order of an impressive amount of diverse data.","conferenceTitle":"Earth Observing Systems VII","conferenceDate":"July 7-10, 2002","conferenceLocation":"Seattle, WA","language":"English","publisher":"SPIE","doi":"10.1117/12.451678","issn":"0277786X","usgsCitation":"Kalvelage, T.A., 2002, Operating the EOSDIS at the land processes DAAC managing expectations, requirements, and performance across agencies, missions, instruments, systems, and user communities, Earth Observing Systems VII, v. 4814, Seattle, WA, July 7-10, 2002, p. 380-391, https://doi.org/10.1117/12.451678.","productDescription":"12 p.","startPage":"380","endPage":"391","numberOfPages":"12","costCenters":[{"id":222,"text":"Earth Resources Observation and Science (EROS) Center","active":true,"usgs":true}],"links":[{"id":233223,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"4814","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a6e75e4b0c8380cd75662","contributors":{"editors":[{"text":"Barnes W.L.","contributorId":128354,"corporation":true,"usgs":false,"organization":"Barnes W.L.","id":536544,"contributorType":{"id":2,"text":"Editors"},"rank":1}],"authors":[{"text":"Kalvelage, T.

In 13 reaches, this flow divides locally around islands and dikes to form 31 branches. This study develops a set of simple linear regression equations for computing expected flow proportions in branches, generally as a function of the total flow within the reach. The equations are based on 533 acoustic Doppler current profiler measurements of flow obtained between 1996 and 2000. Root-mean-square errors of these regressions range from 0.00323 to 0.0895. In seven upstream reaches where flow is known because of flow specifications at the boundaries of the waterway and continuity constraints, the uncertainties of the flow proportions can be used to directly infer the uncertainties of the corresponding flows. In six downstream reaches, the uncertainties of flows are determined by both the uncertainties of the flow proportions and the uncertainties of the total flow in the reach. For these reaches, Monte Carlo simulations quantify the ratios of total uncertainty to flow proportion uncertainty, which range from 1.0026 to 13.984. To facilitate routine calculation, polynomial regression equations are developed to approximate these ratios as a function of flow. Results provide a mechanism for computing the magnitudes and uncertainties of steady-state flows within selected branches of the connecting channels by specifying inflows at the headwaters of St. Clair River, seven intervening tributaries, and Lake St. Clair.</span></p>","language":"English","publisher":"Elsevier","doi":"10.1016/S0380-1330(02)70592-3","usgsCitation":"Holtschlag, D.J., and Koschik, J.A., 2002, Flow distribution in selected branches of St. Clair and Detroit rivers: Journal of Great Lakes Research, v. 28, no. 3, p. 379-395, https://doi.org/10.1016/S0380-1330(02)70592-3.","productDescription":"17 p.","startPage":"379","endPage":"395","numberOfPages":"17","costCenters":[{"id":382,"text":"Michigan Water Science Center","active":true,"usgs":true}],"links":[{"id":233189,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"Canada, United States","state":"Michigan, Ontario","otherGeospatial":"St. Clair and Detroit Rivers","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -83.08135986328124,\n              42.04521345501039\n            ],\n            [\n              -83.0731201171875,\n              42.24071874922666\n            ],\n            [\n              -82.88909912109375,\n              42.31997030030749\n            ],\n            [\n              -82.540283203125,\n              42.26917949243506\n            ],\n            [\n              -82.3809814453125,\n              42.35448465106744\n            ],\n            [\n              -82.3919677734375,\n              42.508552415528634\n            ],\n            [\n              -82.50457763671874,\n              42.56521874494336\n            ],\n            [\n              -82.35626220703124,\n              43.002638523957906\n            ],\n            [\n              -82.452392578125,\n              43.02673743559375\n            ],\n            [\n              -82.60894775390625,\n              42.718768102606326\n            ],\n            [\n              -82.86163330078125,\n              42.68243539838623\n            ],\n            [\n              -83.023681640625,\n              42.466018925787495\n            ],\n            [\n              -83.21044921875,\n              42.216313604344776\n            ],\n            [\n              -83.2159423828125,\n              42.01869237684385\n            ],\n            [\n              -83.08135986328124,\n              42.04521345501039\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"28","issue":"3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a1242e4b0c8380cd54231","contributors":{"authors":[{"text":"Holtschlag, David J. 0000-0001-5185-4928 dholtschlag@usgs.gov","orcid":"https://orcid.org/0000-0001-5185-4928","contributorId":5447,"corporation":false,"usgs":true,"family":"Holtschlag","given":"David","email":"dholtschlag@usgs.gov","middleInitial":"J.","affiliations":[{"id":382,"text":"Michigan Water Science Center","active":true,"usgs":true}],"preferred":true,"id":403456,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Koschik, John A.","contributorId":24020,"corporation":false,"usgs":true,"family":"Koschik","given":"John","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":403455,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

The analysis used twelve 3-wk to 5-wk periods of mid-depth and near-bottom SSC data collected at Point San Pablo every 15 min from 1993-1998. Point San Pablo is within a tidal excursion of a dredged-material disposal site. The SSC data were compared to dredging volume, Julian day, and hydrodynamic and meteorological variables that could affect SSC. Kendall's ??, Spearman's ??, and weighted (by the fraction of valid data in each period) Spearman's ??w correlation coefficients of the variables indicated which variables were significantly correlated with SSC. Wind-wave resuspension had the greatest effect on SSC. Median water-surface elevation was the primary factor affecting mid-depth SSC. Greater depths inhibit wind-wave resuspension of bottom sediment and indicate greater influence of less turbid water from down estuary. Seasonal variability in the supply of erodible sediment is the primary factor affecting near-bottom SSC.

Consistent with usage over the past four decades, we define \"net ecosystem production\" (NEP) as the net carbon accumulation by ecosystems. Past use of this term has been ambiguous, because it has been used conceptually as a measure of carbon accumulation by ecosystems, but it has often been calculated considering only the balance between gross primary production (GPP) and ecosystem respiration. This calculation ignores other carbon fluxes from ecosystems (e.g., leaching of dissolved carbon and losses associated with disturbance). To avoid conceptual ambiguities, we argue that NEP be defined, as in the past, as the net carbon accumulation by ecosystems and that it explicitly incorporate all the carbon fluxes from an ecosystem, including autotrophic respiration, heterotrophic respiration, losses associated with disturbance, dissolved and particulate carbon losses, volatile organic compound emissions, and lateral transfers among ecosystems. Net biome productivity (NBP), which has been proposed to account for carbon loss during episodic disturbance, is equivalent to NEP at regional or global scales. The multi-scale conceptual framework we describe provides continuity between flux measurements made at the scale of soil profiles and chambers, forest inventories, eddy covariance towers, aircraft, and inversions of remote atmospheric flask samples, allowing a direct comparison of NEP estimates made at all temporal and spatial scales.","language":"English","publisher":"Wiley","doi":"10.1890/1051-0761(2002)012[0937:NEPACM]2.0.CO;2","usgsCitation":"Randerson, J.T., Chapin, F.S., Harden, J., Neff, J.C., and Harmon, M.E., 2002, Net ecosystem production: A comprehensive measure of net carbon accumulation by ecosystems: Ecological Applications, v. 12, no. 4, p. 937-947, https://doi.org/10.1890/1051-0761(2002)012[0937:NEPACM]2.0.CO;2.","productDescription":"11 p.","startPage":"937","endPage":"947","costCenters":[{"id":312,"text":"Geology, Minerals, Energy, and Geophysics Science Center","active":true,"usgs":true}],"links":[{"id":489053,"rank":2,"type":{"id":41,"text":"Open Access External Repository Page"},"url":"https://escholarship.org/uc/item/0x90v7pk","text":"External Repository"},{"id":231543,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"12","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a64ece4b0c8380cd72aa1","contributors":{"authors":[{"text":"Randerson, J.

The BACs were detected by liquid chromatography/ion trap mass spectrometry (LC/MS) or tandem mass spectrometry (MS/MS) using an electrospray interface operated in the positive ion mode. This methodology combines the high efficiency of extraction provided by a pressurized fluid and the high sensitivity offered by the ion trap MS/MS. The effects of solvent type and ASE operational variables, such as temperature and pressure, were evaluated. After optimization, a mixture of acetonitrile/water (6:4 or 7:3) was found to be most efficient for extracting BACs from the sediment samples. Extraction recoveries ranged from 95 to 105% for C12 and C14 homologues, respectively. Total method recoveries from fortified sediment samples, using a cleanup step followed by ASE, were 85% for C12BAC and 79% for C14-BAC. The methodology developed in this work provides detection limits in the subnanogram per gram range. Concentrations of BAC homologues ranged from 22 to 206 ??g/kg in sediment samples from different river sites downstream from wastewater treatment plants. The high affinity of BACs for soil suggests that BACs preferentially concentrate in sediment rather than in water.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Analytical Chemistry","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1021/ac010969l","issn":"00032700","usgsCitation":"Ferrer, I., and Furlong, E., 2002, Accelerated solvent extraction followed by on-line solid-phase extraction coupled to ion trap LC/MS/MS for analysis of benzalkonium chlorides in sediment samples: Analytical Chemistry, v. 74, no. 6, p. 1275-1280, https://doi.org/10.1021/ac010969l.","startPage":"1275","endPage":"1280","numberOfPages":"6","costCenters":[],"links":[{"id":207291,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1021/ac010969l"},{"id":232120,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"74","issue":"6","noUsgsAuthors":false,"publicationDate":"2002-02-16","publicationStatus":"PW","scienceBaseUri":"5059e667e4b0c8380cd473c8","contributors":{"authors":[{"text":"Ferrer, I.","contributorId":97260,"corporation":false,"usgs":true,"family":"Ferrer","given":"I.","email":"","affiliations":[],"preferred":false,"id":401173,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Furlong, E.

Ten species among a total of 110 present dominated the 110 samples investigated in the historical study. A cluster analysis of the foraminiferal abundances in the historical study identified five assemblages: Inner Shelf, Middle Shelf, Outer Shelf, Southeastern Shelf and Southwestern Shelf. Specimens with calcareous tests were most prevalent in all the assemblages. A cluster analysis of the modern foraminiferal frequencies from 95 samples also defined five assemblages: Inner Shelf, Middle Shelf, Middle/Outer Shelf Arenaceous, Outer Shelf, and Southern Shelf. Although arenaceous taxa dominate much of the modern fauna, the spatial distribution of the modern assemblages is similar to that of the historical record when presumably unrecognized taxa are eliminated from the data. Both the historical and, to a greater degree, the modern foraminiferal assemblages exhibit a strong correlation with the sediment grain size distribution. ?? 2002 Elsevier Science B.V.

We propose a simple model to account for these events and for a regional pattern of geologic and geophysical features. Aeromagnetic maps reveal some of the most important elements of this pattern, which are several narrow, arcuate anomalies, here referred to as the Northern Nevada rifts. These rifts extend hundreds of kilometers across Nevada and are likely caused by highly magnetic, middle Miocene mafic dikes. With the aid of filtering techniques, the anomalies can be traced into Oregon. Together with other geologic features, such as fold axes, dike swarms, and faults, they produce a spoke-like pattern fanning over <span>220°&nbsp;</span> of arc that converges toward a point near the Oregon-Idaho border (lat <span>∼44°N</span>). A possible cause for this pattern is a point source of stress at the base of the crust related to the formation of the Yellowstone hotspot. The spoke-like pattern, however, does not persist at large distances from the emerging hotspot; several hundred kilometers to the south, the Northern Nevada rifts deviate significantly (<span>&gt;30°</span>) from a radial trend. We show that a simple model-imposing a point source of stress at the base of the crust and a regional stress field aligned with the presumed middle Miocene stress direction-fits the observed fracture pattern. It thus accounts for both the radial pattern present near the nascent hotspot and the far-field pattern due to regional stresses.</p>","language":"English","publisher":"GeoScienceWorld","doi":"10.1130/0091-7613(2002)030<0647:LSFRTI>2.0.CO;2","usgsCitation":"Glen, J., and Ponce, D., 2002, Large-scale fractures related to inception of the Yellowstone hotspot: Geology, v. 30, no. 7, p. 647-650, https://doi.org/10.1130/0091-7613(2002)030<0647:LSFRTI>2.0.CO;2.","productDescription":"4 p.","startPage":"647","endPage":"650","costCenters":[{"id":49175,"text":"Geology, Energy & Minerals Science Center","active":true,"usgs":true}],"links":[{"id":233227,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Wyoming","otherGeospatial":"Yellowstone hotspot","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -111.06353759765625,\n              44.51805165000559\n            ],\n            [\n              -110.159912109375,\n              44.51805165000559\n            ],\n            [\n              -110.159912109375,\n              44.999767019181284\n            ],\n            [\n              -111.06353759765625,\n              44.999767019181284\n            ],\n            [\n              -111.06353759765625,\n              44.51805165000559\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"30","issue":"7","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a4498e4b0c8380cd66c2f","contributors":{"authors":[{"text":"Glen, J.M.G.","contributorId":38330,"corporation":false,"usgs":true,"family":"Glen","given":"J.M.G.","email":"","affiliations":[],"preferred":false,"id":401521,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Ponce, D.

The life history characteristics included longevity (maximum age), the rate at which asymptotic length was approached (K from the von Bertalanffy growth equation), the mean back-calculated length at age, and growth rates during the first year of life (mm/degree-day and mm/d). The mean water temperature and number of days in the growing season averaged 1.3 times greater in the southern than in the northern latitudes, while degree-days averaged twice as great. The longevity of all species except freshwater drum increased significantly from south to north, but the relationships between maximum age and latitude were curvilinear for short-lived species and linear for long-lived species. The von Bertalanffy growth coefficient for river carpsuckers and saugers increased from north to south, as indicated by significant negative relationships between K and latitude. Mean back-calculated length at age was negatively related to latitude for freshwater drums (???age 4) and saugers (ages 1-5) but positively related to latitude for river carpsuckers (???age 6). One of the growth rates examined (mm/degree-day) increased significantly from low to high latitudes for emerald shiners, sicklefin chubs, freshwater drums, and river carpsuckers during the first growing season. The other growth rate (mm/d) increased significantly from low to high latitudes for emerald shiners but was inversely related to latitude for saugers.

It is known that meso-scale flows appear in the regions over underwater volcanoes or hot rocks. Their origin is connected with heat flux and hot jets released from underwater volcanoes or faults in a sea bottom. Values of mean velocities and turbulent velocities in plumes were estimated. Quasiconstant magnetic fields induced by a hot jet and a vortex over a plume top are about 1-40 nT. Variable magnetic fields are about 0.1-1 nT. These magnetic disturbances in the sea medium create an additional natural electromagnetic background that must be considered when making detailed magnetic surveys. ?? 2002 Elsevier Science Ltd.

The fish were orally contaminated with Aroclor 1254 and held either with or without food for 5 months before they were subjected to a 10-min handling disturbance. Food-deprived fish were given 0, 1, 10 or 100 mg PCB kg<sup>−1</sup> and the fed fish 0 or 100 mg PCB kg<sup>−1</sup>. Plasma cortisol, glucose and lactate levels were measured at 0 (pre-handling), 1, 3, 6 and 23 h after the handling disturbance. Food-deprived control fish had elevated plasma cortisol levels compared with fed fish before handling. These basal cortisol levels were suppressed by PCB in food-deprived fish, and elevated by PCB in fed fish. The immediate cortisol and glucose responses to handling disturbance were suppressed by PCB in a dose-dependent way in food-deprived fish. Although these responses were also lowered by PCB in the fed fish, the effect was much less pronounced than in food-deprived fish. There were only minor effects on plasma lactate responses. Our findings suggest that the stress responses of the Arctic charr are compromised by PCB and that the long-term fasting, typical of high-latitude fish, makes these species particularly sensitive to organochlorines such as PCB.</p>","language":"English","publisher":"Elsevier","doi":"10.1016/S1532-0456(02)00069-8","issn":"15320456","usgsCitation":"Jorgensen, E., Vijayan, M., Aluru, N., and Maule, A., 2002, Fasting modifies Aroclor 1254 impact on plasma cortisol, glucose and lactate responses to a handling disturbance in Arctic charr: Comparative Biochemistry and Physiology, Part C: Toxicology & Pharmacology, v. 132, no. 2, p. 235-245, https://doi.org/10.1016/S1532-0456(02)00069-8.","productDescription":"11 p.","startPage":"235","endPage":"245","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[{"id":654,"text":"Western Fisheries Research Center","active":true,"usgs":true}],"links":[{"id":232038,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"132","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a0effe4b0c8380cd536f6","contributors":{"authors":[{"text":"Jorgensen, E.H.","contributorId":13782,"corporation":false,"usgs":true,"family":"Jorgensen","given":"E.H.","affiliations":[],"preferred":false,"id":401120,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Vijayan, M.M.","contributorId":33087,"corporation":false,"usgs":true,"family":"Vijayan","given":"M.M.","email":"","affiliations":[],"preferred":false,"id":401121,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Aluru, N.","contributorId":80454,"corporation":false,"usgs":true,"family":"Aluru","given":"N.","email":"","affiliations":[],"preferred":false,"id":401123,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Maule, A.G.","contributorId":45067,"corporation":false,"usgs":true,"family":"Maule","given":"A.G.","email":"","affiliations":[],"preferred":false,"id":401122,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

Variability in these three factors can result in more than one c‐Q loop shape for a given rank order of end‐member solute concentrations. The number of resulting hysteresis patterns and their relative frequency depends on the rank order of solute concentrations and on their separation in absolute value. In ambiguous cases the c‐Q loop shape is determined by the relative “prominence” of the event water versus soil water components. This “prominence” is broadly defined as a capacity to influence the total streamflow concentration and may result from a combination of end‐member volume, timing, or concentration. The modeling results indicate that plausible hydrological variability in field situations can confound the interpretation of c‐Q plots, even when fundamental end‐member mixing assumptions are satisfied.</p></div>","language":"English","publisher":"American Geophysical Union","doi":"10.1029/2001WR000971","usgsCitation":"Chanat, J.G., Rice, K.C., and Hornberger, G., 2002, Consistency of patterns in concentration‐discharge plots: Water Resources Research, v. 38, no. 8, p. 22-1-22-10, https://doi.org/10.1029/2001WR000971.","productDescription":"Article 1147; 10 p.","startPage":"22-1","endPage":"22-10","costCenters":[{"id":614,"text":"Virginia Water Science Center","active":true,"usgs":true},{"id":37280,"text":"Virginia and West Virginia Water Science Center ","active":true,"usgs":true}],"links":[{"id":232001,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"38","issue":"8","noUsgsAuthors":false,"publicationDate":"2002-08-17","publicationStatus":"PW","scienceBaseUri":"5059fa00e4b0c8380cd4d880","contributors":{"authors":[{"text":"Chanat, Jeffrey G. 0000-0002-3629-7307 jchanat@usgs.gov","orcid":"https://orcid.org/0000-0002-3629-7307","contributorId":5062,"corporation":false,"usgs":true,"family":"Chanat","given":"Jeffrey","email":"jchanat@usgs.gov","middleInitial":"G.","affiliations":[{"id":614,"text":"Virginia Water Science Center","active":true,"usgs":true}],"preferred":true,"id":401111,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Rice, Karen C. 0000-0002-9356-5443 kcrice@usgs.gov","orcid":"https://orcid.org/0000-0002-9356-5443","contributorId":1998,"corporation":false,"usgs":true,"family":"Rice","given":"Karen","email":"kcrice@usgs.gov","middleInitial":"C.","affiliations":[{"id":614,"text":"Virginia Water Science Center","active":true,"usgs":true}],"preferred":false,"id":401113,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Hornberger, George M.","contributorId":63894,"corporation":false,"usgs":true,"family":"Hornberger","given":"George M.","affiliations":[],"preferred":false,"id":401112,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}
