The session, 'Management of the Double-crested Cormorant in the Laurentian Great Lakes Region,' was held on 12 June 2001 and contained 18 presentations. Topics included cormorant-fish interactions, effects of cormorant nesting on colonies of other waterbirds, cormorant population dynamics, habitat use by foraging cormorants, evaluation of management techniques, and policy and conflict assessment on cormorant-related issues. The collection is organized into four basic topics: management of populations, effects of cormorants on other colonial waterbirds, foraging habitats of cormorants, and effects of cormorants on fisheries. A primary objective of this collection is to provide information and useful tools for managing cormorants in the Great Lakes.</p>","language":"English","publisher":"Elsevier","doi":"10.1016/S0380-1330(02)70570-4","usgsCitation":"Stapanian, M.A., 2002, Interspecific interactions, habitat use, and management of double-crested cormorants (<i>Phalacrocorax auritus</i>) in the Laurentian Great Lakes: An introduction: Journal of Great Lakes Research, v. 28, no. 2, p. 119-124, https://doi.org/10.1016/S0380-1330(02)70570-4.","productDescription":"6 p.","startPage":"119","endPage":"124","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[{"id":324,"text":"Great Lakes Science Center","active":true,"usgs":true}],"links":[{"id":133475,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"28","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e49d8e4b07f02db5df8da","contributors":{"authors":[{"text":"Stapanian, Martin A. 0000-0001-8173-4273 mstapanian@usgs.gov","orcid":"https://orcid.org/0000-0001-8173-4273","contributorId":3425,"corporation":false,"usgs":true,"family":"Stapanian","given":"Martin","email":"mstapanian@usgs.gov","middleInitial":"A.","affiliations":[{"id":324,"text":"Great Lakes Science Center","active":true,"usgs":true}],"preferred":true,"id":309687,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

Each transect included only one of the following habitats: (1) offshore of a breeding island or roosting/loafing area for cormorants (&ldquo;refuge&rdquo;), (2) reefs or shoals, (3) open water, or (4) offshore of an island shoreline that had evidence of development by humans. Foraging cormorants were recorded most often offshore of refuges and least often on open water. There was no difference between the numbers of foraging cormorants/km<sup>2</sup>&nbsp;recorded offshore of developed shorelines and on reefs and shoals. More than half of all boats recorded were on transects that were within 1 km of developed shorelines. Among those transects&nbsp;&gt;&nbsp;1 km from developed shorelines, there were no differences among the habitats for the number of boats of either length class. The respective ranks of the 31 transect means of the numbers of cormorants/km<sup>2</sup>&nbsp;and the numbers of boats/km<sup>2</sup>&nbsp;in either length class were uncorrelated. The results suggest that (1) cormorants select foraging habitats based mainly on shoreline type, distance from shoreline, and depth, and (2) the amount of boat traffic is influenced by proximity to port and trip objectives, including sport angling and recreational boating. Although there is overlap in habitat use by cormorants and humans, this overlap is not complete. The perception of cormorants as a threat to fish populations may in part be due to this overlap.</p>\n</div>","language":"English","publisher":"Elsevier","doi":"10.1016/S0380-1330(02)70574-1","usgsCitation":"Stapanian, M.A., and Bur, M.T., 2002, Overlap in offshore habitat use by double-crested cormorants and boaters in western Lake Erie: Journal of Great Lakes Research, v. 28, no. 2, p. 172-181, https://doi.org/10.1016/S0380-1330(02)70574-1.","productDescription":"10 p.","startPage":"172","endPage":"181","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[{"id":324,"text":"Great Lakes Science Center","active":true,"usgs":true}],"links":[{"id":133641,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"28","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4ae4e4b07f02db689e4f","contributors":{"authors":[{"text":"Stapanian, Martin A. 0000-0001-8173-4273 mstapanian@usgs.gov","orcid":"https://orcid.org/0000-0001-8173-4273","contributorId":3425,"corporation":false,"usgs":true,"family":"Stapanian","given":"Martin","email":"mstapanian@usgs.gov","middleInitial":"A.","affiliations":[{"id":324,"text":"Great Lakes Science Center","active":true,"usgs":true}],"preferred":true,"id":309688,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Bur, Michael T.","contributorId":102015,"corporation":false,"usgs":true,"family":"Bur","given":"Michael","email":"","middleInitial":"T.","affiliations":[],"preferred":false,"id":309689,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

Some potential sources of errors in turbulence measurements made with ADCPs include inaccuracy of Doppler-shift measurements, poor temporal and spatial measurement resolution, and inaccuracy of multi-dimensional velocities resolved from one-dimensional velocities measured at separate locations. Results from laboratory measurements of mean velocity and turbulence statistics made with two pulse-coherent ADCPs in 0.87 meters of water are used to illustrate several of inherent sources of error in ADCP turbulence measurements. Results show that processing algorithms and beam configurations have important effects on turbulence measurements. ADCPs can provide reasonable estimates of many turbulence parameters; however, the accuracy of turbulence measurements made with commercially available ADCPs is often poor in comparison to standard measurement techniques.","largerWorkTitle":"Hydraulic Measurements and Experimental Methods","conferenceTitle":"Hydraulic Measurements and Experimental Methods 2002","conferenceDate":"28 July 2002 through 1 August 2002","conferenceLocation":"Estes Park, CO","language":"English","isbn":"0784406553","usgsCitation":"Nystrom, E., Oberg, K.A., and Rehmann, C., 2002, Measurement of Turbulence with Acoustic Doppler Current Profilers - Sources of Error and Laboratory Results, <i>in</i> Hydraulic Measurements and Experimental Methods, Estes Park, CO, 28 July 2002 through 1 August 2002, p. 346-355.","startPage":"346","endPage":"355","numberOfPages":"10","costCenters":[],"links":[{"id":232098,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a52f1e4b0c8380cd6c795","contributors":{"editors":[{"text":"Wahl T.L.Pugh C.A.Oberg K.A.Vermeyen T.B.Wahl T.L.Pugh C.A.Oberg K.A.Vermeyen T.B.","contributorId":128321,"corporation":true,"usgs":false,"organization":"Wahl T.L.Pugh C.A.Oberg K.A.Vermeyen T.B.Wahl T.L.Pugh C.A.Oberg K.A.Vermeyen T.B.","id":536527,"contributorType":{"id":2,"text":"Editors"},"rank":1}],"authors":[{"text":"Nystrom, E.A.","contributorId":85749,"corporation":false,"usgs":true,"family":"Nystrom","given":"E.A.","email":"","affiliations":[],"preferred":false,"id":399760,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Oberg, K.

It is known that macroinvertebrates make up an important part of wetland food webs and ecosystem function; however, our understanding of species distribution within and among wetlands has only recently received attention.  We investigated the macroinvertebrates of a freshwater marsh (Prentiss Bay) in the Les Chenaux Island Area of Northern Lake Huron, Michigan.  Macroinvertebrate taxa diversity and functional feeding group composition were compared between two habitats.  A shallow depositional habitat with higher vegetation diversity and little wave action was compared to a deeper erosional habitat with fewer plant species and more wave action.  A total of 83 taxa were collected over the summer of 1996, representing two phyla (Arthropoda and Mollusca) and five classes (Arachnida, Bivalvia, Malacostraca, Gastropoda and Insecta).  A total of 79 genera were identified, with 92% being insects (39 families composed of at least 73 genera).  Of the total, 42 insect genera were common to both habitats,while relatively fewer were collected exclusively from the erosional compared the depositional habitat.  When habitats were pooled, predators comprised about 50% of the functional group taxa, while gathering collectors and shredders each were about 20%.  Filtering collectors and scrapers each represented < 10%.  When comparing habitats, there was a relatively higher percentage of predators and shredders in the depositional habitat, while all other functional groups were lower.  These data suggest that vegetation diversity, depth and wave action affect taxa composition and functional group organization of the Prentiss Bay marsh.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Great Lakes Entomologist","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","collaboration":"Out-of-print","usgsCitation":"Merritt, R., Benbow, M., and Hudson, P., 2002, Wetland macroinvertebrates of Prentiss Bay, Lake Huron, Michigan: diversity and functional group composition: Great Lakes Entomologist, v. 35, no. 2, p. 149-160.","productDescription":"p. 149-160","startPage":"149","endPage":"160","numberOfPages":"11","costCenters":[{"id":324,"text":"Great Lakes Science Center","active":true,"usgs":true}],"links":[{"id":133313,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"35","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e49e1e4b07f02db5e47fd","contributors":{"authors":[{"text":"Merritt, R.W.","contributorId":30588,"corporation":false,"usgs":true,"family":"Merritt","given":"R.W.","email":"","affiliations":[],"preferred":false,"id":309597,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Benbow, M.E.","contributorId":13586,"corporation":false,"usgs":true,"family":"Benbow","given":"M.E.","email":"","affiliations":[],"preferred":false,"id":309596,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Hudson, P.L.","contributorId":9623,"corporation":false,"usgs":true,"family":"Hudson","given":"P.L.","email":"","affiliations":[],"preferred":false,"id":309595,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

Active subglacial volcanism and a vast (>106 km3) extent of subglacial volcanic structures have been interpreted from aerogeophysical surveys over central West Antarctica in the past decade, combined with results from 1960s and 1970s aeromagnetic profiles over the WAIS. Modelling of magnetic anomalies constrained by radar ice sounding shows volcanic sources at the base of the ice throughout large areas, whose subglacially erupted hyaloclastite edifices have been eroded by moving ice, as in Iceland. The 1800 m-high divide of the WAIS is underlain by the 400 km-long volcanic Sinuous Ridge, which rises above sea level; most hyaloclastite edifices there have also been glacially removed, indicating migration of the ice divide through time. Northeast of the divide of the WAIS there is a 400-nT positive magnetic anomaly over the shallowest, most rugged bedrock topography (elevation +380 m above sea level), probably comprising subaerially erupted flows erupted when the Sinuous Ridge area was deglaciated. Uplift of the Sinuous Ridge may have forced the advance of the WAIS. Other aspects of the subglacial volcanism in Antarctica can be observed in Iceland and have a direct bearing on our understanding of the subglacial conditions of the WAIS and its dynamics.","language":"English","publisher":"The Geological Society","doi":"10.1144/GSL.SP.2002.202.01.17","usgsCitation":"Behrendt, J.C., Blankenship, D.D., Morse, D.L., Finn, C., and Bell, R., 2002, Subglacial volcanic features beneath the West Antarctic Ice Sheet interpreted from aeromagnetic and radar ice sounding: Geological Society Special Publication, no. 202, p. 337-355, https://doi.org/10.1144/GSL.SP.2002.202.01.17.","productDescription":"19 p.","startPage":"337","endPage":"355","costCenters":[{"id":35995,"text":"Geology, Geophysics, and Geochemistry Science Center","active":true,"usgs":true}],"links":[{"id":231559,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"otherGeospatial":"West Antarctica","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -2961.5625,\n              -70.93100353239011\n            ],\n            [\n              -2955.322265625,\n              -78.45542534118532\n            ],\n            [\n              -2918.232421875,\n              -78.57790682347503\n            ],\n            [\n              -2923.857421875,\n              -66.19600891267761\n            ],\n            [\n              -2936.513671875,\n              -60.84491057364912\n            ],\n            [\n              -2954.4433593750005,\n              -64.99793920061401\n            ],\n            [\n              -2961.5625,\n              -70.93100353239011\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","issue":"202","noUsgsAuthors":false,"publicationDate":"2003-02-03","publicationStatus":"PW","scienceBaseUri":"505b9d14e4b08c986b31d620","contributors":{"authors":[{"text":"Behrendt, John C. jbehrendt@usgs.gov","contributorId":25945,"corporation":false,"usgs":true,"family":"Behrendt","given":"John","email":"jbehrendt@usgs.gov","middleInitial":"C.","affiliations":[{"id":218,"text":"Denver Federal Center","active":false,"usgs":true},{"id":213,"text":"Crustal Imaging and Characterization Team","active":false,"usgs":true}],"preferred":false,"id":399772,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Blankenship, D.

Historic information was collated from the literature, area ornithologists, and museums, whereas contemporary data were derived from surveys conducted throughout the main wintering range in Argentina, Uruguay, and Brazil during the austral summers of 1999 and 2001. Variable circular plot sampling was used to estimate population densities. During 1999, the highest concentration of Buff-breasted Sandpipers in Argentina was in southern Bahía Samborombón (General Lavalle District) and areas north of Mar Chiquita coastal lagoon. During 2001, the highest concentrations in Brazil were at Ilha da Torotama and Lagoa do Peixe National Park. During 1999 and 2001, the highest concentrations of Buff-breasted Sandpipers in Uruguay were found along three lagoons (Laguna de Rocha, Laguna de Castillos, and Laguna Garzón) bordering the Atlantic Ocean. Population densities (birds/ha) of Buff-breasted Sandpipers were 0.11 (95% C.I. = 0.04–0.31) in Argentina, 1.62 (0.67–3.93) in Brazil, and 1.08 (0.37–3.18) in Uruguay. High turnover rates at survey sites, due to the formation of large, mobile flocks, contributed to moderately large confidence intervals around our population density estimates. Nevertheless, compared with historic accounts of Buff-breasted Sandpipers, our survey data indicate the population size of this species has declined substantially since the late 1800s and contemporary information suggests the species has continued to decline during the past three decades. Buff-breasted Sandpipers were found almost exclusively in pasturelands and appear to depend heavily upon intensive grazing by livestock, which maintain suitable short grass conditions. We discuss the need for protection of critical areas and proper range management to ensure appropriate habitat remains available for the species, and provide suggestions for future research needs.</span></p>","language":"English","publisher":"Wilson Ornithological Society","doi":"10.1676/0043-5643(2002)114[0044:CSOTBB]2.0.CO;2","usgsCitation":"Lanctot, R.B., Blanco, D., Dias, R.A., Isacch, J.P., Gill, V., de Almeida, J.B., Delhey, K., Petracci, P.F., Bencke, G.A., and Balbueno, R.A., 2002, Conservation status of the buff-breasted sandpiper: Historic and contemporary distribution and abundance in south America: The Wilson Bulletin, v. 114, no. 1, p. 44-72, https://doi.org/10.1676/0043-5643(2002)114[0044:CSOTBB]2.0.CO;2.","productDescription":"29 p.","startPage":"44","endPage":"72","costCenters":[{"id":114,"text":"Alaska Science Center","active":true,"usgs":true}],"links":[{"id":478796,"rank":0,"type":{"id":41,"text":"Open Access External Repository Page"},"url":"https://doi.org/10.1676/0043-5643(2002)114[0044:csotbb]2.0.co;2","text":"External Repository"},{"id":338010,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"otherGeospatial":"South America","volume":"114","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"58d23b91e4b0236b68f828f8","contributors":{"authors":[{"text":"Lanctot, Richard B.","contributorId":31894,"corporation":false,"usgs":true,"family":"Lanctot","given":"Richard","email":"","middleInitial":"B.","affiliations":[{"id":17786,"text":"Carleton University","active":true,"usgs":false},{"id":7029,"text":"Queen's University, Kingston, Ontario, Canada","active":true,"usgs":false},{"id":135,"text":"Biological Resources Division","active":false,"usgs":true},{"id":6987,"text":"U.S. Fish and Wildlife Sevice","active":true,"usgs":false}],"preferred":false,"id":685531,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Blanco, D.E.","contributorId":173932,"corporation":false,"usgs":false,"family":"Blanco","given":"D.E.","email":"","affiliations":[],"preferred":false,"id":685532,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Dias, Rafael A.","contributorId":189643,"corporation":false,"usgs":false,"family":"Dias","given":"Rafael","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":685533,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Isacch, Juan P.","contributorId":189644,"corporation":false,"usgs":false,"family":"Isacch","given":"Juan","email":"","middleInitial":"P.","affiliations":[],"preferred":false,"id":685534,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Gill, Verena A.","contributorId":140658,"corporation":false,"usgs":false,"family":"Gill","given":"Verena A.","affiliations":[{"id":6678,"text":"U.S. Fish and Wildlife Service, Alaska Maritime National Wildlife Refuge","active":true,"usgs":false}],"preferred":false,"id":685535,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"de Almeida, Juliana Bose","contributorId":189645,"corporation":false,"usgs":false,"family":"de Almeida","given":"Juliana","middleInitial":"Bose","affiliations":[],"preferred":false,"id":685536,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Delhey, Kaspar","contributorId":189646,"corporation":false,"usgs":false,"family":"Delhey","given":"Kaspar","email":"","affiliations":[],"preferred":false,"id":685537,"contributorType":{"id":1,"text":"Authors"},"rank":7},{"text":"Petracci, Pablo F.","contributorId":189647,"corporation":false,"usgs":false,"family":"Petracci","given":"Pablo","email":"","middleInitial":"F.","affiliations":[],"preferred":false,"id":685538,"contributorType":{"id":1,"text":"Authors"},"rank":8},{"text":"Bencke, Glayson A.","contributorId":189648,"corporation":false,"usgs":false,"family":"Bencke","given":"Glayson","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":685539,"contributorType":{"id":1,"text":"Authors"},"rank":9},{"text":"Balbueno, Rodrigo A.","contributorId":189649,"corporation":false,"usgs":false,"family":"Balbueno","given":"Rodrigo","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":685540,"contributorType":{"id":1,"text":"Authors"},"rank":10}]}}

Fluctuations of poleward long-period alongshore wind stress anomalies (AWSA) are coherent with the sea level anomalies. However, the wind stress cannot entirely account for the observed sea level signals. The sea level fluctuations are also correlated with sea level fluctuations observed further south at Los Angeles and Tumaco, Columbia, which showed a poleward phase propagation of the sea level signal. We suggest that the sea level fluctuations were, to a greater degree, forced by the passage of remotely generated and coastally trapped waves that were generated along the equator and propagated to the north along the west coast of North America. However, both local and remote AWSA can significantly modulate the sea level signals. The arrival of coastally trapped waves began in the spring of 1997, which is earlier than previous strong El Niño events such as the 1982–1983 event.</span></p>","language":"English","publisher":"Elsevier","doi":"10.1016/S0079-6611(02)00047-2","usgsCitation":"Ryan, H.F., and Noble, M., 2002, Sea level response to ENSO along the central California coast: How the 1997-1998 event compares with the historic record: Progress in Oceanography, v. 54, no. 1-4, p. 149-169, https://doi.org/10.1016/S0079-6611(02)00047-2.","productDescription":"21 p.","startPage":"149","endPage":"169","numberOfPages":"21","costCenters":[],"links":[{"id":231881,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"California","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -121.25,\n              36\n            ],\n            [\n              -121.25,\n              39\n            ],\n            [\n              -123.75,\n              39\n            ],\n            [\n              -123.75,\n              36\n            ],\n            [\n              -121.25,\n              36\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","volume":"54","issue":"1-4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505b87e9e4b08c986b31670c","contributors":{"authors":[{"text":"Ryan, H.

Three of the methods use different ion-exchange resin forms—bags, capsules, and membranes—and the fourth was conventional chemical extraction. The first experiment compared nutrient extraction data from a medium of sand saturated with a nutrient solution. The second and third experiments used Nakai and Sheppard series soils from Canyonlands National Park, which are relatively high in soil carbonates. The second experiment compared nutrient extraction data provided by the four methods from soils equilibrated at two temperatures, “warm” and “cold.” The third experiment extracted nutrients from the same soils in a field equilibration. Our results show that the four extraction techniques are not comparable. This conclusion is due to differences among the methods in the net quantities of nutrients extracted from equivalent soil volumes, in the proportional representation of nutrients within similar soils and treatments, in the measurement of nutrients that were added in known quantities, and even in the order of nutrients ranked by net abundance. We attribute the disparities in nutrient measurement among the different resin forms to interacting effects of the inherent differences in resin exchange capacity, differences among nutrients in their resin affinities, and possibly the relatively short equilibration time for laboratory trials. One constraint for measuring carbonate-related nutrients in high-carbonate soils is the conventional ammonium acetate extraction method, which we suspect of dissolving fine CaCO<sub>3</sub> particles that are more abundant in Nakai series soils, resulting in erroneously high Ca<sup>2+</sup> estimates. For study of plant-available nutrients, it is important to identify the nutrients of foremost interest and understand differences in their resin sorption dynamics to determine the most appropriate extraction method.</p>","language":"English","publisher":"John Ewers","doi":"10.1097/00010694-200210000-00005","usgsCitation":"Sherrod, S.K., Belnap, J., and Miller, M.E., 2002, Comparison of methods for nutrient measurement in calcareous soils: Ion-exchange resin bag, capsule, membrane, and chemical extractions: Soil Science, v. 167, no. 10, p. 666-679, https://doi.org/10.1097/00010694-200210000-00005.","productDescription":"14 p.","startPage":"666","endPage":"679","costCenters":[{"id":290,"text":"Forest and Rangeland Ecosystem Science Center","active":false,"usgs":true}],"links":[{"id":232034,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"167","issue":"10","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059f874e4b0c8380cd4d0fd","contributors":{"authors":[{"text":"Sherrod, S.

We illustrate how stratigraphic ordering, sedimentological, and historical data can be used quantitatively in the process of estimating earthquake ages. Calibrated radiocarbon age distributions are used directly from layer dating through recurrence intervals and recurrence probability estimation. The method does not eliminate subjective judgements in event dating, but it does provide a means of systematically and objectively approaching the dating process. Date distributions for the most recent 14 events at Wrightwood are based on sample and contextual evidence in Fumal et al. (2002) and site context and slip history in Weldon et al. (2002). Pallett Creek event and dating descriptions are from published sources. For the five most recent events at Wrightwood, our results are consistent with previously published estimates, with generally comparable or narrower uncertainties. For Pallett Creek, our earthquake date estimates generally overlap with previous results but typically have broader uncertainties. Some event date estimates are very sensitive to details of data interpretation. The historical earthquake in 1857 ruptured the ground at both sites but is not constrained by radiocarbon data. Radiocarbon ages, peat accumulation rates, and historical constraints at Pallett Creek for event X yield a date estimate in the earliest 1800s and preclude a date in the late 1600s. This event is almost certainly the historical 1812 earthquake, as previously concluded by Sieh et al. (1989). This earthquake also produced ground deformation at Wrightwood. All events at Pallett Creek, except for event T, about A.D. 1360, and possibly event I, about A.D. 960, have corresponding events at Wrightwood with some overlap in age ranges. Event T falls during a period of low sedimentation at Wrightwood when conditions were not favorable for recording earthquake evidence. Previously proposed correlations of Pallett Creek X with Wrightwood W3 in the 1690s and Pallett Creek event V with W5 around 1480 (Fumal et al., 1993) appear unlikely after our dating reevaluation. Apparent internal inconsistencies among event, layer, and dating relationships around events R and V identify them as candidates for further investigation at the site. Conditional probabilities of earthquake recurrence were estimated using Poisson, lognormal, and empirical models. The presence of 12 or 13 events at Wrightwood during the same interval that 10 events are reported at Pallett Creek is reflected in mean recurrence intervals of 105 and 135 years, respectively. Average Poisson model 30-year conditional probabilities are about 20% at Pallett Creek and 25% at Wrightwood. The lognormal model conditional probabilities are somewhat higher, about 25% for Pallett Creek and 34% for Wrightwood. Lognormal variance ??ln estimates of 0.76 and 0.70, respectively, imply only weak time predictability. Conditional probabilities of 29% and 46%, respectively, were estimated for an empirical distribution derived from the data alone. Conditional probability uncertainties are dominated by the brevity of the event series; dating uncertainty contributes only secondarily. Wrightwood and Pallett Creek event chronologies both suggest variations in recurrence interval with time, hinting that some form of recurrence rate modulation may be at work, but formal testing shows that neither series is more ordered than might be produced by a Poisson process.","language":"English","publisher":"Seismological Society of America","doi":"10.1785/0120000605","usgsCitation":"Biasi, G., Weldon, R., Fumal, T.E., and Seitz, G.G., 2002, Paleoseismic event dating and the conditional probability of large earthquakes on the southern San Andreas fault, California: Bulletin of the Seismological Society of America, v. 92, no. 7, p. 2761-2781, https://doi.org/10.1785/0120000605.","productDescription":"21 p.","startPage":"2761","endPage":"2781","costCenters":[{"id":237,"text":"Earthquake Science Center","active":true,"usgs":true}],"links":[{"id":231537,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"California","otherGeospatial":"San Andreas fault","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -117.75146484375,\n              34.66935854524543\n            ],\n            [\n              -117.04833984375001,\n              34.161818161230386\n            ],\n            [\n              -116.27929687499999,\n              33.669496972795535\n            ],\n            [\n              -115.94970703125,\n              33.55970664841198\n            ],\n            [\n              -117.301025390625,\n              34.49750272138159\n            ],\n            [\n              -117.740478515625,\n              34.82282272723702\n            ],\n            [\n              -117.75146484375,\n              34.66935854524543\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"92","issue":"7","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a7443e4b0c8380cd77548","contributors":{"authors":[{"text":"Biasi, G.

The data set contained seven classes comparable to Anderson Level I and 24 classes comparable to Anderson Level II/III. Twelve scenes of dual-date TM data were processed with methods that included principal components analysis, stratification into spectrally consistent units, separate classification of upland, wetland, and urban areas, and a hybrid supervised/unsupervised classification called \"guided clustering.\" The final data had overall accuracies of 94% for Anderson Level I upland classes, 77% for Level II/III upland classes, and 84% for Level II/III wetland classes. Classification accuracies for deciduous and coniferous forest were 95% and 93%, respectively, and forest species' overall accuracies ranged from 70% to 84%. Limited availability of acceptable imagery necessitated use of an early May date in a majority of scene pairs, perhaps contributing to lower accuracy for upland deciduous forest species. The mixed deciduous/coniferous forest class had the lowest accuracy, most likely due to distinctly classifying a purely mixed class. Mixed forest signatures containing oak were often confused with pure oak. Guided clustering was seen as an efficient classification method, especially at the tree species level, although its success relied in part on image dates, accurate ground troth, and some analyst intervention. ?? 2002 Elsevier Science Inc.

We evaluated potential constraints on full recovery, including (1) exposure to residual oil; (2) food limitation; and (3) intrinsic demographic limitations on population growth rates. In this paper, we synthesize the findings from our work and incorporate information from other harlequin duck research and monitoring programs to provide a comprehensive evaluation of the response of this species to the 'Exxon Valdez' spill. We conclude that harlequin duck populations had not fully recovered by 1998. Furthermore, adverse effects continued as many as 9 yr after the oil spill, in contrast to the conventional paradigm that oil spill effects on bird populations are short-lived. These conclusions are based on the findings that (1) elevated cytochrome P450 (CYP1A) induction on oiled areas indicated continued exposure to oil in 1998; (2) adult female winter survival was lower on oiled than unoiled areas during 1995 to 1998; (3) fall population surveys by the Alaska Department of Fish and Game indicated numerical declines in oiled areas during 1995 to 1997; and (4) densities on oiled areas in 1996 and 1997 were lower than expected using models that accounted for effects of habitat attributes. Based on hypothesized links between oil contamination and demography, we suggest that harlequin duck population recovery was constrained primarily by continued oil exposure. Full population recovery will also be delayed by the time necessary for intrinsic population growth to allow return to pre-spill numbers following cessation of residual oil spill effects. Although not all wildlife species were affected by the 'Exxon Valdez' oil spill, and some others may have recovered quickly from any effects, harlequin duck life history characteristics and benthic, nearshore feeding habits make them susceptible to both initial and long-term oil spill effects.</p>","language":"English","publisher":"Inter-Research Science Center","doi":"10.3354/meps241271","issn":"01718630","usgsCitation":"Esler, D., Bowman, T.D., Trust, K.A., Ballachey, B.E., Dean, T.A., Jewett, S.C., and O’Clair, C.E., 2002, Harlequin duck population recovery following the 'Exxon Valdez' oil spill: Progress, process and constraints: Marine Ecology Progress Series, v. 241, p. 271-286, https://doi.org/10.3354/meps241271.","productDescription":"16 p.","startPage":"271","endPage":"286","costCenters":[{"id":114,"text":"Alaska Science Center","active":true,"usgs":true},{"id":116,"text":"Alaska Science Center Biology MFEB","active":true,"usgs":true}],"links":[{"id":488568,"rank":1,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.3354/meps241271","text":"Publisher Index Page"},{"id":231689,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Alaska","otherGeospatial":"Prince William Sound","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -148.21380615234375,\n              60.02095215374802\n            ],\n            [\n              -146.73065185546875,\n              60.02095215374802\n            ],\n            [\n              -146.73065185546875,\n              60.648954953475844\n            ],\n            [\n              -148.21380615234375,\n              60.648954953475844\n            ],\n            [\n              -148.21380615234375,\n              60.02095215374802\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"241","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a2f76e4b0c8380cd5cde1","contributors":{"authors":[{"text":"Esler, Daniel 0000-0001-5501-4555 desler@usgs.gov","orcid":"https://orcid.org/0000-0001-5501-4555","contributorId":5465,"corporation":false,"usgs":true,"family":"Esler","given":"Daniel","email":"desler@usgs.gov","affiliations":[{"id":114,"text":"Alaska Science Center","active":true,"usgs":true},{"id":12437,"text":"Simon Fraser University, Centre for Wildlife Ecology","active":true,"usgs":false},{"id":116,"text":"Alaska Science Center Biology MFEB","active":true,"usgs":true}],"preferred":true,"id":400662,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Bowman, Timothy D.","contributorId":80779,"corporation":false,"usgs":false,"family":"Bowman","given":"Timothy","email":"","middleInitial":"D.","affiliations":[],"preferred":false,"id":400667,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Trust, Kimberly A.","contributorId":42503,"corporation":false,"usgs":false,"family":"Trust","given":"Kimberly","email":"","middleInitial":"A.","affiliations":[{"id":6987,"text":"U.S. Fish and Wildlife Sevice","active":true,"usgs":false}],"preferred":false,"id":400668,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Ballachey, Brenda E. 0000-0003-1855-9171 bballachey@usgs.gov","orcid":"https://orcid.org/0000-0003-1855-9171","contributorId":2966,"corporation":false,"usgs":true,"family":"Ballachey","given":"Brenda","email":"bballachey@usgs.gov","middleInitial":"E.","affiliations":[{"id":116,"text":"Alaska Science Center Biology MFEB","active":true,"usgs":true},{"id":114,"text":"Alaska Science Center","active":true,"usgs":true}],"preferred":true,"id":400663,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Dean, Thomas A.","contributorId":187562,"corporation":false,"usgs":false,"family":"Dean","given":"Thomas","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":400665,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Jewett, Stephen C.","contributorId":94397,"corporation":false,"usgs":true,"family":"Jewett","given":"Stephen","email":"","middleInitial":"C.","affiliations":[],"preferred":false,"id":400666,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"O’Clair, Charles E.","contributorId":60571,"corporation":false,"usgs":false,"family":"O’Clair","given":"Charles","email":"","middleInitial":"E.","affiliations":[],"preferred":false,"id":400664,"contributorType":{"id":1,"text":"Authors"},"rank":7}]}}

We used measured associations with landscape patterns to build accurate predictive habitat models that were quickly and easily applied (i.e., required no additional data collection in the field to make predictions). We used classification trees (a nonparametric alternative to discriminant function analysis, logistic regression, and other generalized linear models) to model nesting habitat of red-naped sapsuckers (Sphyrapicus nuchalis), northern flickers (Colaptes auratus), tree swallows (Tachycineta bicolor), and mountain chickadees (Parus gambeli) in the Uinta Mountains of northeastern Utah, USA. We then tested the predictive capability of the models with independent data collected in the field the following year. The models built for the northern flicker, red-naped sapsucker, and tree swallow were relatively accurate (84%, 80%, and 75% nests correctly classified, respectively) compared to the models for the mountain chickadee (50% nests correctly classified). All four models were more selective than a null model that predicted habitat based solely on a gross association with aspen forests. We conclude that associations with landscape patterns can be used to build relatively accurate, easy to use, predictive models for some species. Our results stress, however, that both selecting the proper scale at which to assess landscape associations and empirically testing the models derived from those associations are crucial for building useful predictive models.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Landscape Ecology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1023/A:1020219914926","issn":"09212973","usgsCitation":"Lawler, J., and Edwards, T., 2002, Landscape patterns as habitat predictors: Building and testing models for cavity-nesting birds in the Uinta Mountains of Utah, USA: Landscape Ecology, v. 17, no. 3, p. 233-245, https://doi.org/10.1023/A:1020219914926.","startPage":"233","endPage":"245","numberOfPages":"13","costCenters":[],"links":[{"id":207137,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1023/A:1020219914926"},{"id":231808,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"17","issue":"3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a4418e4b0c8380cd66855","contributors":{"authors":[{"text":"Lawler, J.J.","contributorId":8641,"corporation":false,"usgs":true,"family":"Lawler","given":"J.J.","email":"","affiliations":[],"preferred":false,"id":400709,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Edwards, T.C.","contributorId":72163,"corporation":false,"usgs":true,"family":"Edwards","given":"T.C.","email":"","affiliations":[],"preferred":false,"id":400710,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

Removal of pathogens and other contaminants by bank filtration is assumed, but regulatory agencies question the effectiveness of this process. To investigate transport processes of biological constituents, advective groundwater traveltimes to production wells under the influence of surface water need to be established first to determine appropriate water-quality sampling schedules. This paper presents the results of a study of bank filtration at a well field in southwestern Ohio. Field parameters such as water level, specific conductance, and water temperature were measured at least hourly at a streamflow gaging station and at five monitoring wells each at two separate sites, corresponding to two nearby production wells. Water-quality samples also were collected in all wells and the streamflow gaging station. Specific conductance is directly related to concentration of chloride, a chemically conservative constituent. Cross-correlation methods were used to determine the average traveltime from the river to the monitoring wells. Traveltimes based on specific conductance ranged from approximately 20 h to 10 days at one site and 5 days to 3 months at the other site. Calculated groundwater flow velocities ranged from 2.1 ?? 10-3 to 6.0 ?? 10-3 cm/s and 3.5 ?? 10-4 to 7.1 ?? 10-4 cm/s at the two sites. Data collected when a production well is continuously pumping reveal shorter and more consistent traveltimes than when the same well is pumped intermittently. ?? 2002 Elsevier Science B.V.

At Fort Knox, the Re-Os molybdenite date is identical to the U-Pb zircon age for the host intrusion, supporting an intrusive-related origin for the deposit. However, 40Ar/39Ar dates from hydrothermal and igneous mica are considerably younger. At the Pogo deposit, Re-Os molybdenite dates are also much older than 40Ar/39Ar dates from hydrothermal mica, but dissimilar to the age of local granites. These age relationships indicate that the Re-Os molybdenite method records the timing of sulfide and gold mineralization, whereas much younger 40Ar/39Ar dates are affected by post-ore thermal events, slow cooling, and/or systemic analytical effects. The results of this study complement a growing body of evidence to indicate that the Re-Os chronometer in molybdenite can be an accurate and robust tool for establishing timing relations in ore systems.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Geology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1130/0091-7613(2002)030<0791:ATOSAG>2.0.CO;2","issn":"00917613","usgsCitation":"Selby, D., Creaser, R., Hart, C., Rombach, C., Thompson, J.F., Smith, M.T., Bakke, A., and Goldfarb, R., 2002, Absolute timing of sulfide and gold mineralization: A comparison of Re-Os molybdenite and Ar-Ar mica methods from the Tintina Gold Belt, Alaska: Geology, v. 30, no. 9, p. 791-794, https://doi.org/10.1130/0091-7613(2002)030<0791:ATOSAG>2.0.CO;2.","startPage":"791","endPage":"794","numberOfPages":"4","costCenters":[],"links":[{"id":207030,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1130/0091-7613(2002)030<0791:ATOSAG>2.0.CO;2"},{"id":231574,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"30","issue":"9","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059e64ce4b0c8380cd47320","contributors":{"authors":[{"text":"Selby, D.","contributorId":57623,"corporation":false,"usgs":true,"family":"Selby","given":"D.","email":"","affiliations":[],"preferred":false,"id":400645,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Creaser, R.A.","contributorId":50319,"corporation":false,"usgs":true,"family":"Creaser","given":"R.A.","affiliations":[],"preferred":false,"id":400643,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Hart, C.J.R.","contributorId":67228,"corporation":false,"usgs":true,"family":"Hart","given":"C.J.R.","email":"","affiliations":[],"preferred":false,"id":400646,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Rombach, C.S.","contributorId":52228,"corporation":false,"usgs":true,"family":"Rombach","given":"C.S.","affiliations":[],"preferred":false,"id":400644,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Thompson, J.

Each spring from 1997 to 2000, we released 197-299 lamprey with surgically implanted radio transmitters. Unique transmitter codes and the date and time of reception at each antenna site were downloaded electronically, and initial processing was conducted to eliminate false positive signals. The resulting large Oracle database was analyzed using an Arc View-based coding protocol. Underwater antennas positioned outside the fishway entrances detected lamprey approaches, and antennas positioned immediately inside the entrances indicated successful entries. Entrance efficiency (the number of lamprey that successfully entered a fishway divided by the number that approached that fishway) was compared for different types of entrances (main entrances versus orifice entrances) and entrance locations (powerhouse versus spillway). Lamprey used orifice-type entrances less frequently than main entrances, and passage success was generally low (< 50%) at all entrances to fishways at Bonneville Dam (the lowest dam in the system). Lamprey activity at the entrances was highest at night, and entrance success was significantly higher at The Dalles Dam (the next dam upstream from Bonneville Dam) than at Bonneville Dam. In 1999 and 2000, construction modifications were made to Bonneville Dam spillway entrances, and water velocity at these entrances was reduced at night. Modifications to increase lamprey attachment at the entrances improved lamprey entrance efficiency, but entrance efficiency during reduced velocity tests was not significantly higher than during control conditions.","largerWorkTitle":"Hydrobiologia","language":"English","doi":"10.1023/A:1021394521450","issn":"00188158","usgsCitation":"Moser, M., Matter, A., Stuehrenberg, L., and Bjornn, T., 2002, Use of an extensive radio receiver network to document Pacific lamprey (Lampetra tridentata) entrance efficiency at fishways in the Lower Columbia River, USA, <i>in</i> Hydrobiologia, v. 483, p. 45-53, https://doi.org/10.1023/A:1021394521450.","startPage":"45","endPage":"53","numberOfPages":"9","costCenters":[],"links":[{"id":207207,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1023/A:1021394521450"},{"id":231958,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"483","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505bbeb6e4b08c986b32973d","contributors":{"authors":[{"text":"Moser, M.L.","contributorId":92006,"corporation":false,"usgs":true,"family":"Moser","given":"M.L.","email":"","affiliations":[],"preferred":false,"id":400740,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Matter, A.L.","contributorId":77324,"corporation":false,"usgs":true,"family":"Matter","given":"A.L.","email":"","affiliations":[],"preferred":false,"id":400739,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Stuehrenberg, L.C.","contributorId":46722,"corporation":false,"usgs":true,"family":"Stuehrenberg","given":"L.C.","email":"","affiliations":[],"preferred":false,"id":400738,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Bjornn, T.C.","contributorId":9033,"corporation":false,"usgs":true,"family":"Bjornn","given":"T.C.","affiliations":[],"preferred":false,"id":400737,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

Water was equilibrated with oil samples and analyzed for MTBE, BTEX, and the oxygenate tert-amyl methyl ether (TAME) by purge-and-trap concentration followed by GC/FID analysis. Raoult's law was used to calculate oil-phase concentrations of MTBE, BTEX, and TAME from aqueous-phase concentrations. MTBE, TAME, and BTEX were not detected in any of five new motor oil samples, whereas these compounds were found at significant concentrations in all six samples of the used motor oil tested for MTBE and all four samples tested for TAME and BTEX.

During this study, 1,998 individuals of resident species were collected from stream sections considered to be within a common area of distribution for each species. Forty-five individuals of resident and nonresident species were captured upstream of these areas, and eight of these fish were considered to be larger than individuals considered typical for each species. Small mammal dispersal theory concepts were used to classify and describe fish movements outside of common areas of distribution. These movements were identified as important in maintaining population connectivity within stream drainages, contributing to reducing the potential for local extinctions of populations and to the recolonization of unoccupied habitats. This study highlights the need for continued study of fish movements in stream drainages and for development of appropriate resource management strategies based partly on the spatial dynamics of fish populations and communities.</span></p>","language":"English","publisher":"American Fisheries Society","doi":"10.1577/1548-8659(2002)131%3C0791:OOTDOF%3E2.0.CO;2","usgsCitation":"Larson, G.L., Hoffman, R.L., and Moore, S.E., 2002, Observations of the distributions of five fish species in a small Appalachian stream: Transactions of the American Fisheries Society, v. 131, no. 4, p. 791-796, https://doi.org/10.1577/1548-8659(2002)131%3C0791:OOTDOF%3E2.0.CO;2.","productDescription":"6 p.","startPage":"791","endPage":"796","numberOfPages":"6","costCenters":[{"id":290,"text":"Forest and Rangeland Ecosystem Science Center","active":false,"usgs":true}],"links":[{"id":133962,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","otherGeospatial":"Cosby Creek, Rock Creek","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -83.22143554687499,\n              35.747069546016\n            ],\n            [\n              -83.19130897521973,\n              35.747069546016\n            ],\n            [\n              -83.19130897521973,\n              35.78551286273958\n            ],\n            [\n              -83.22143554687499,\n              35.78551286273958\n            ],\n            [\n              -83.22143554687499,\n              35.747069546016\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"131","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a68e4b07f02db63b185","contributors":{"authors":[{"text":"Larson, Gary L. gary_l._larson@usgs.gov","contributorId":2990,"corporation":false,"usgs":true,"family":"Larson","given":"Gary","email":"gary_l._larson@usgs.gov","middleInitial":"L.","affiliations":[],"preferred":true,"id":323666,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Hoffman, Robert L.","contributorId":52931,"corporation":false,"usgs":true,"family":"Hoffman","given":"Robert","email":"","middleInitial":"L.","affiliations":[],"preferred":false,"id":323667,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Moore, S.
