The heat-pulse flowmeter has no moving parts and operates on the tag–trace principle. It is an improved version of the flowmeter developed by the Water Research Centre in England in 1975. The U.S. Geological Survey's heat-pulse flowmeter has a flow-measuring range in water of 0.06–6 m/min, and can resolve velocity differences as slow as 0.01 m/min. This is an order of magnitude slower than the stall speed of spinner flowmeters. The flowmeter is 1.16 m long and 44 mm in diameter. It was calibrated in columns of 76 and 152 mm diameter, to correspond to the boreholes studied.

The objectives of the study were to: (1) describe the streamflow characteristics, sediment transport, and stream-channel morphology in the Pheasant Branch basin; and (2) relate the above factors to changes caused by urbanization and project the effect of urbanization on the hydrology and channel morphology of the study area.</p>\n<p>&nbsp;</p>\n<p>Streamflow data were collected at five sites for 4 years in the basin to defme present streamflow conditions. Suspended-sediment data also were collected at these sites. In addition, periodic surveys of monumented channel cross sections were made and compared with a survey from an earlier study to document changes in the channel over a period of 10 years.</p>\n<p>The suspended-sediment data show a decrease in suspended-sediment load through the fully urbanized reach of the stream in 3 of the 4 years studied. This corresponds with the slight net decrease in cross-section area in this reach for the same period. Possible explanations for the decrease in suspended-sediment loads through this reach include (1) sediment being trapped at the five drop structures and the Park Street erosion-control structure and (2) sediment being deposited in overbank areas throughout the reach. Farther downstream, the suspended-sediment load decreased through the Pheasant Branch marsh during a year of high flow but increased through the marsh in 2 of the 3 years for which complete data are available. The marsh is not acting as a net sediment trap in some years.</p>\n<p>A rainfall-runoff model was calibrated and verified for the basin upstream from U.S. Highway 12. This model was used to simulate 68 years of summer flood hydrographs for three conditions: Current land use, projected urban development, and complete urban development of all lands in the basin. Analysis of simulated flood flows indicates that projected urban development would double the mean annual flood peaks at U.S. Highway 12. Complete development of the basin would increase the mean annual flood peak by a factor of 2.4.</p>\n<p>From 1971 to 1977, the mean streambed elevation lowered by almost 2 feet, and the mean channel width increased by more than 35 percent in the reach downstream from the fully urbanized part of the basin. In other reaches, the mean streambed elevation lowered by more than a foot. Changes in channel cross sections after 1977 were smaller.</p>\n<p>Increases in flood flow would tend to enlarge the channel. An increase in the mean annual flood by a factor of 2. 0 to 2.4 will cause a 40 to 50 percent increase in channel width and a 30 to 40 percent increase in channel depth.</p>","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/wri854068","collaboration":"Prepared in cooperation with the University of Wisconsin-Extension, Geological and Natural History Survey and the City of Middleton","usgsCitation":"Krug, W., and Goddard, G.L., 1986, Effects of urbanization on streamflow, sediment loads, and channel morphology in Pheasant Branch basin near Middleton, Wisconsin: U.S. Geological Survey Water-Resources Investigations Report 85-4068, vi, 82 p., https://doi.org/10.3133/wri854068.","productDescription":"vi, 82 p.","numberOfPages":"94","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[{"id":677,"text":"Wisconsin Water Science Center","active":true,"usgs":true}],"links":[{"id":415474,"rank":3,"type":{"id":36,"text":"NGMDB Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_36247.htm","linkFileType":{"id":5,"text":"html"}},{"id":123391,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/wri/1985/4068/report-thumb.jpg"},{"id":56979,"rank":2,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/wri/1985/4068/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"country":"United States","state":"Wisconsin","county":"Dane County","city":"Middleton","otherGeospatial":"Pheasant Branch","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -89.589,\n              43.049\n            ],\n            [\n              -89.589,\n              43.16\n            ],\n            [\n              -89.469,\n              43.16\n            ],\n            [\n              -89.469,\n              43.049\n            ],\n            [\n              -89.589,\n              43.049\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a26e4b07f02db60fd46","contributors":{"authors":[{"text":"Krug, W.R.","contributorId":23147,"corporation":false,"usgs":true,"family":"Krug","given":"W.R.","email":"","affiliations":[],"preferred":false,"id":199300,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Goddard, G.

Murres (primarily common murres <i>Uria aalge</i>), Atlantic puffins <i>Fratercula arctica</i>, and schooling fish (primarily capelin <i>Mallotus villosus</i>) were highly aggregated at spatial scales ranging from 0.25 to 15 km. Patchiness of murres, puffins and schooling fish was scale-dependent, as indicated by significantly higher variance-to-mean ratios at large measurement distances than at the minimum distance, 0.25 km. Patch scale of puffins ranged from 2.5 to 15 km, of murres from 3 to 8.75 km, and of schooling fish from 1.25 to 15 km. Patch scale of birds and schooling fish was similar m 6 out of 9 comparisons. Correlation between seabirds and schooling birds was significant at the minimum measurement distance in 6 out of 12 comparisons. Correlation was scale-dependent, as indicated by significantly higher coefficients at large measurement distances than at the minimum distance. Tracking scale, as indicated by the maximum significant correlation between birds and schooling fish, ranged from 2 to 6 km. Our analysis showed that extended aggregations of seabirds are associated with extended aggregations of schooling fish and that correlation of these marine carnivores with their prey is scale-dependent.</p>","language":"English","publisher":"Inter-Research Science Center","usgsCitation":"Schneider, D.C., and Piatt, J.F., 1986, Scale-dependent correlation of seabirds with schooling fish in a coastal ecosystem: Marine Ecology Progress Series, v. 32, p. 237-246.","productDescription":"10 p.","startPage":"237","endPage":"246","costCenters":[{"id":114,"text":"Alaska Science Center","active":true,"usgs":true}],"links":[{"id":336992,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":336990,"rank":1,"type":{"id":15,"text":"Index Page"},"url":"https://www.int-res.com/abstracts/meps/v32/","text":"Volume 32 on Journals's Website"}],"country":"Canada","state":"Newfoundland","otherGeospatial":"Avalon Channel, Grand Banks","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -53.5638427734375,\n              46.35451083736523\n            ],\n            [\n              -51.7620849609375,\n              46.35451083736523\n            ],\n            [\n              -51.7620849609375,\n              47.908978314728714\n            ],\n            [\n              -53.5638427734375,\n              47.908978314728714\n            ],\n            [\n              -53.5638427734375,\n              46.35451083736523\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"32","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"58bfd51ae4b014cc3a3ba64d","contributors":{"authors":[{"text":"Schneider, Davod C.","contributorId":7800,"corporation":false,"usgs":false,"family":"Schneider","given":"Davod","email":"","middleInitial":"C.","affiliations":[],"preferred":false,"id":681137,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Piatt, John F. 0000-0002-4417-5748 jpiatt@usgs.gov","orcid":"https://orcid.org/0000-0002-4417-5748","contributorId":3025,"corporation":false,"usgs":true,"family":"Piatt","given":"John","email":"jpiatt@usgs.gov","middleInitial":"F.","affiliations":[{"id":114,"text":"Alaska Science Center","active":true,"usgs":true},{"id":116,"text":"Alaska Science Center Biology MFEB","active":true,"usgs":true},{"id":117,"text":"Alaska Science Center Biology WTEB","active":true,"usgs":true}],"preferred":true,"id":681138,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

Birds were counted along shrubby and shrubless transects during the 1982 breeding season. Species richness and total density of birds were greater on shrubby transects. Five species were more abundant on shrubby transects. Availability of woody nesting substrates best explained differences in bird species abundances. Differences in shrub coverages between transects were probably the result of different land-use practices. Land management practices which modify shrub coverages can alter the composition of passerine bird communities.","language":"English","publisher":"Ottawa Field-Naturalists'

Radioactivity in the carcass and viscera was evaluated in juvenile fish fed steroid-incorporated diet (tritium and carbon-14 labelled MT and 30 μg unlabelled MT/g feed) for 21 days, and depletion was monitored for 21 days after return to an untreated diet.</p><p>Radioactivity was detected in the carcass within 1 h after initial feeding and reached highest levels by 6 h. Most of the radioactivity (&gt; 90%) was in the viscera during the 21 days the radio-labelled diet was being fed.

The 1981 version repealed the Black Bass Act and corrected certain insufficiencies in the original Lacey and Black Bass Acts. A 1977 executive order instructs federal agencies, to the extent permitted by law, to restrict the introductions of exotic species into federally owned or controlled lands and waters. The National Environmental Policy Act of 1969 and the Endangered Species Act of 1973 indirectly relate to the stocking of exotic fish. The first requires each federal agency to prepare an environmental impact statement if a proposed action, such as a species introduction, may significantly affect the environment. The second regulation prohibits the importation of endangered or threatened animals, and specific exotic fishes could be in one of these categories. The U.S. Fish and Wildlife Service, as part of the Department of Interior's charge, initiated a program in 1977 at Gainesville, Florida, to conduct and coordinate research on non-native fish introduced or considered for stocking into United States waters.

The most differentiated lavas (rhyodacite and pumice) are also the most contaminated.</p><p>On Milos, by contrast, these processes are very extensive. They are expressed in the<sup>143</sup>Nd/<sup>144</sup>Nd vs.<sup>87</sup>Sr/<sup>86</sup>Sr diagram as a continuous mixing curve between a mantle and a crustal end member pole defined by schists and metavolcanic rocks outcropping on these volcanoes. In contrast with Santorini, the least differentiated lavas on Milos are the most contaminated. These isotopic singularities can be correlated with the geodynamic evolution of the Aegean subduction zone, consisting of alternating tectonic phases of distension and compression. The genesis of rhyolitic magmas can be linked to the two phases of distension, and the contamination of the calc-alkaline mantle-derived magmas with the intermediate compressive phase.</p><p>The isotopic characteristics of uncontaminated calc-alkaline primitive magmas of Milos and Santorini are directly comparable to those of magmas generated in subduction zones for which a contribution of subducted sediments to partial melts from the mantle is suggested, such as in the Aleutian, Sunda, and lesser Antilles island arcs. However, in spite of the importance of the sediment pile in the eastern Mediterranen oceanic crust (6–10 km), the contribution of the subducted terrigenous materials remains of limited amplitude.</p>","language":"English","publisher":"Elesvier","doi":"10.1016/0012-821X(86)90018-X","issn":"0012821X","usgsCitation":"Briqueu, L., Javoy, M., Lancelot, J., and Tatsumoto, M., 1986, Isotope geochemistry of recent magmatism in the Aegean arc: Sr, Nd, Hf, and O isotopic ratios in the lavas of Milos and Santorini-geodynamic implications: Earth and Planetary Science Letters, v. 80, no. 1-2, p. 41-54, https://doi.org/10.1016/0012-821X(86)90018-X.","productDescription":"14 p.","startPage":"41","endPage":"54","numberOfPages":"14","costCenters":[],"links":[{"id":223830,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"80","issue":"1-2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a3f8ae4b0c8380cd645e4","contributors":{"authors":[{"text":"Briqueu, L.","contributorId":43106,"corporation":false,"usgs":true,"family":"Briqueu","given":"L.","email":"","affiliations":[],"preferred":false,"id":371278,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Javoy, M.","contributorId":107859,"corporation":false,"usgs":true,"family":"Javoy","given":"M.","email":"","affiliations":[],"preferred":false,"id":371280,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Lancelot, J.R.","contributorId":25301,"corporation":false,"usgs":true,"family":"Lancelot","given":"J.R.","email":"","affiliations":[],"preferred":false,"id":371277,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Tatsumoto, M.","contributorId":76798,"corporation":false,"usgs":true,"family":"Tatsumoto","given":"M.","email":"","affiliations":[],"preferred":false,"id":371279,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

In a sample of 63 documented cases, 22 percent of the landslide dams failed in less than 1 day after formation, and half failed within 10 days. Overtopping was by far the most frequent cause of landslide-dam failure. Backwater flooding behind landslide dams can inundate communities and valuable agricultural land. Floods from the failure of landslide dams are smaller than floods from constructed dams impounding bodies of water with the same potential energy, but larger than floods from failure of ice dams. Secondary effects of landslide-dam failures include additional landslides as reservoir levels drop rapidly, aggradation of valleys upstream and downstream of the dams, and avulsive channel changes downstream.","conferenceTitle":"Landslide Dams: Processes, Risk, and Mitigation.

Assimilation of silicic crust has also occurred along with fractionation. Two varieties of inclusions found in Holocene rhyolite flows, hornblende gabbros and aphyric andesites, provide information on the crystallization path followed by lavas parental to the rhyolite. The hornblende gabbros are magmatic cumulate residues and their mineral assemblages are preserved evidence of the phases that crystallized from an andesitic precursor lava to generate the rhyolite lavas. The andesitic inclusions represent samples of a parental andesite and record the early part of the differentiation history. Olivine, plagioclase and augite crystallization begins the differentiation history, followed by the disappearance of olivine and augite through reaction with the liquid to form orthopyroxene and amphibole. Further crystallization of the assemblage plagioclase, amphibole, orthopyroxene, magnetite, and apatite from a high-SiO2 andesite leads to rhyolite. This final crystallization process occurs on a cotectic that is nearly horizontal in temperature-composition space. Since a large amount of crystallization occurs over a limited temperature interval, a compositional gap develops between rhyolite and high SiO2 andesite. Liquidus surfaces with shallow slopes in temperature-composition space are characteristic of several late-stage crystallization assemblages in the andesite to rhyolite compositional range. Experimentally produced plagioclase+ amphibole+orthopyroxene+magnetite and plagioclase+ augite+low-Ca pyroxene+magnetite cotectics have liquidus slopes that are nearly flat. At other calc-alkaline volcanic centers crystallization processes involving large compositional changes over small temperature intervals may also be important in the development of bimodal volcanism (i.e. the existence of a composition gap). At Mt. Mazama and Mt. St. Helens, USA and Aso Caldera and Shikotsu, Japan the amphibole-bearing assemblage was important. At Krakatau, Indonesia and Katmai, USA, an augite+orthopyroxene-bearing assemblage was important. In addition to its role in the production of a compositional gap between intermediate and rhyolitic lavas, the crystallization process increases the H2O content of the residual liquid. This rapid increase in residual liquid volatile content which results from the precipitation of a large proportion of crystalline solids may be an important factor among several that lead to explosive silicic eruptions. ?? 1986 Springer-Verlag.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Contributions to Mineralogy and Petrology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisherLocation":"Springer-Verlag","doi":"10.1007/BF00572157","issn":"00107999","usgsCitation":"Grove, T., and Donnelly-Nolan, J., 1986, The evolution of young silicic lavas at Medicine Lake Volcano, California: Implications for the origin of compositional gaps in calc-alkaline series lavas: Contributions to Mineralogy and Petrology, v. 92, no. 3, p. 281-302, https://doi.org/10.1007/BF00572157.","startPage":"281","endPage":"302","numberOfPages":"22","costCenters":[],"links":[{"id":205479,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1007/BF00572157"},{"id":224428,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"92","issue":"3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505babeae4b08c986b323171","contributors":{"authors":[{"text":"Grove, T.L.","contributorId":22088,"corporation":false,"usgs":true,"family":"Grove","given":"T.L.","email":"","affiliations":[],"preferred":false,"id":371229,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Donnelly-Nolan, J.M.","contributorId":104936,"corporation":false,"usgs":false,"family":"Donnelly-Nolan","given":"J.M.","email":"","affiliations":[],"preferred":false,"id":371230,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

SIR images were coregistered with Landsat and existing maps as a guide to exploration of the buried paleodrainages (radar rivers) first discovered by SIR-A. Field observations explain the radar responses of three types of radar rivers, RR-1, RR-2, and RR-3. RR-1 (broad, aggraded valleys or basins filled with alluvium) generally give a dark response relative to the surrounding radar-bright tone of the wind-roughened, discontinuously sand-covered bedrock of the remnant interfluves. The alluvial fill in some of the RR-1 valleys gives a locally intermediate to bright response where cemented by diagenetic CaCO3 (caliche). The RR-2 type (braided channels inset in the RR-1 valleys) are filled with noncalichified, loose sediment, and are visible on SIR because of the \"caliche effect\"-the dark response of unconsolidated alluvium in the inset channels contrasts with the brighter response of calichified alluvium in the broad valleys. The third type, RR-3 (narrow, long, bedrock-incised channels), which are partly visible on the ground and on Landsat in areas where the sand sheet is patchy, are conspicuous on SIR because the dark response of their unconsolidated channel fill contrasts with the brighter response of the surrounding bedrock. Disconformably overlying and concealing the RR-1 valleys, the RR- 2 channels, and parts of the RR-3 channels are eolian sand-sheetsheet de- deposits, which in turn are locally overridden by trains of barchan dunes.</span></p>","language":"English","publisher":"IEEE","doi":"10.1109/TGRS.1986.289678","issn":"01962892","usgsCitation":"McCauley, J., Breed, C.S., Schaber, G.G., McHugh, W.P., Issawi, B., Haynes, C.V., Grolier, M.J., and El Kilani, A., 1986, Paleodrainages of the Eastern Sahara-The radar rivers revisited (SIR-A/B Implications for a Mid-Tertiary Trans-Afnrcan Drainage System): IEEE Transactions on Geoscience and Remote Sensing, v.

The study area lies entirely within the marginal Pacific tectonic domain. Proceeding east to west from the continental margin to the interior, the basalts reveal an isotopic transition in mantle source material and/or degree of crustal interaction. In the east, many of the rocks are found to merge both chemically and isotopically with those previously reported from the Japanese and Taiwan island-arc terrains. In the west, clear evidence exists for component(s) of Late Archean continental lithosphere to be present in some samples. A major crustal structure, the Tan-Lu fault, marks the approximate boundary between continental margin and interior isotopic behaviors. Although the isotopic signature of the western basalts has characteristics of lower-crustal contamination, a subcrustal lithosphere, i.e. an attached mantle keel, is probably more likely to be the major contributor of their continental “flavor”. The transition from continental margin to interior is very pronounced for Pb isotopes, although Sr and Nd isotopes also combine to yield correlated patterns that deviate strikingly from the mid-ocean ridge basalt (MORB) and oceanic-island trends. The most distinctive chemical attribute of this continental lithosphere component is its diminished U/Pb as reflected in the Pb isotopic composition when compared to sources of MORB, oceanic-island and island-arc volcanic rocks. Somewhat diminished Sm/Nd and elevated Rb/Sr, especially in comparison to the depleted asthenospheric mantle, are also apparent from the Nd- and Sr-isotopic ratios.</p></div></div></div>","language":"English","publisher":"Elsevier","doi":"10.1016/0168-9622(86)90054-0","issn":"00092541","usgsCitation":"Peng, Z.C., Zartman, R., Futa, K., and Chen, D., 1986, Pb-, Sr- and Nd-Isotopic systematics and chemical characteristics of cenozoic basalts, Eastern China: Chemical Geology, v. 59, no. 1, p. 3-33, https://doi.org/10.1016/0168-9622(86)90054-0.","productDescription":"31 p.","startPage":"3","endPage":"33","numberOfPages":"31","costCenters":[],"links":[{"id":224048,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"59","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a75fde4b0c8380cd77e74","contributors":{"authors":[{"text":"Peng, Z.

However, Se levels in scoters (34.4 ppm, dry wt) were similar to those in livers of dabbling ducks (Anas spp.) in the nearby San Joaquin Valley where reproduction was impaired severely.</p>","language":"English","publisher":"Wiley","doi":"10.2307/3801489","usgsCitation":"Ohlendorf, H.M., Lowe, R.W., Kelly, P.R., and Harvey, T.E., 1986, Selenium and heavy metals in San Francisco Bay diving ducks: Journal of Wildlife Management, v. 50, no. 1, p. 64-70, https://doi.org/10.2307/3801489.","productDescription":"7 p.","startPage":"64","endPage":"70","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":198246,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"California","otherGeospatial":"San Francisco Bay","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -122.59656918719827,\n              37.957325469924925\n            ],\n            [\n              -122.59656918719827,\n              37.601089561175186\n            ],\n            [\n              -122.20620193662234,\n              37.601089561175186\n            ],\n            [\n              -122.20620193662234,\n              37.957325469924925\n            ],\n            [\n              -122.59656918719827,\n              37.957325469924925\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","volume":"50","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a00e4b07f02db5f7d11","contributors":{"authors":[{"text":"Ohlendorf, Harry M.","contributorId":60291,"corporation":false,"usgs":true,"family":"Ohlendorf","given":"Harry","email":"","middleInitial":"M.","affiliations":[],"preferred":false,"id":335510,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Lowe, Roy W.","contributorId":50847,"corporation":false,"usgs":false,"family":"Lowe","given":"Roy","email":"","middleInitial":"W.","affiliations":[],"preferred":false,"id":335512,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Kelly, Paul R.","contributorId":175074,"corporation":false,"usgs":false,"family":"Kelly","given":"Paul","email":"","middleInitial":"R.","affiliations":[],"preferred":false,"id":335513,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Harvey, Thomas E.","contributorId":38089,"corporation":false,"usgs":true,"family":"Harvey","given":"Thomas","email":"","middleInitial":"E.","affiliations":[],"preferred":false,"id":335511,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}
