During the dry season of 1999, we investigated the influence of hydroperiod on the species composition and dormancy patterns of freshwater copepod communities in seasonal wetlands of Everglades National Park, Florida, U.S.A. The habitats were characterized by an annual dry season, from December through June. We sampled at two locations: the Long Pine Key area of the Rocky Glades region (short hydroperiod, ca. 4-5 months), and western Taylor Slough (intermediate hydroperiod, ca. 8-10 months). Both areas have experienced a reduction in natural hydroperiods and an increase in the frequency of dry-down. We collected weekly plankton samples from Rocky Glades solution holes to assess the potential species pool of copepods. To document the taxa capable of surviving dry-down by resting, we performed three immersion trials in which we rehydrated, in laboratory aquaria, sediment patches from solution holes and surface soils from all stations. Only a subset of the planktonic species collected emerged from the dried sediments. The cyclopoids Microcyclops rubellus and Paracyclops poppei were dominant. This is the first record of diapause for P. poppei. Species distributions from the different hydroperiod soil patches indicated that more diapausing species occurred at the sites that dried for shorter periods. Emerging individuals of M. rubellus and P. poppei were mainly ovigerous females, demonstrating a resting strategy seldom before recorded. The cyclopoid Diacyclops nearcticus had not been previously reported to diapause, but they emerged from the dried sediments in our trials. Our collections included six new records for Florida: Diacyclops nearcticus, Megacyclops latipes, Orthocyclops modestus, Elaphoidella marjoryae, Bryocamptus sp. and Bryocamptus cf. newyorkensis. Paracyclops poppei, Macrocyclops fuscus and Arctodiaptomus floridanus are new records for Everglades National Park. Clearly, diapause is an important strategy for the persistence of copepods in short-hydroperiod wetlands. The duration of the dry period appears to be inversely related to the number of species that emerge from diapause.","largerWorkTitle":"Hydrobiologia","language":"English","doi":"10.1023/A:1013161210836","issn":"00188158","usgsCitation":"Bruno, M., Loftus, W., Reid, J., and Perry, S., 2001, Diapause in copepods (Crustacea) from ephemeral habitats with different hydroperiods in Everglades National Park (Florida, U.S.A.), <i>in</i> Hydrobiologia, v. 453-454, p. 295-308, https://doi.org/10.1023/A:1013161210836.","startPage":"295","endPage":"308","numberOfPages":"14","costCenters":[],"links":[{"id":232735,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":207626,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1023/A:1013161210836"}],"volume":"453-454","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a00a8e4b0c8380cd4f847","contributors":{"authors":[{"text":"Bruno, M.C.","contributorId":17402,"corporation":false,"usgs":true,"family":"Bruno","given":"M.C.","email":"","affiliations":[],"preferred":false,"id":397766,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Loftus, W.F.","contributorId":29363,"corporation":false,"usgs":true,"family":"Loftus","given":"W.F.","email":"","affiliations":[],"preferred":false,"id":397767,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Reid, J.W.","contributorId":43531,"corporation":false,"usgs":true,"family":"Reid","given":"J.W.","email":"","affiliations":[],"preferred":false,"id":397768,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Perry, S.A.","contributorId":50113,"corporation":false,"usgs":true,"family":"Perry","given":"S.A.","email":"","affiliations":[],"preferred":false,"id":397769,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

This review synthesizes information on marine resources in two of the first MPAs established in the USA, namely Virgin Islands National Park (1962) and Buck Island Reef National Monument (1961), and provides compelling evidence that greater protection is needed, based on data from some of the longest running research projects on coral reefs, reef fish assemblages, and seagrass beds for the Caribbean. Most of the stresses affecting marine resources throughout the Caribbean (e.g. damage from boats, hurricanes and coral diseases) are also causing deterioration in these MPAs. Living coral cover has decreased and macroalgal cover has increased. Seagrass densities have decreased because of storms and anchor damage. Intensive fishing in the US Virgin Islands has caused loss of spawning aggregations and decreases in mean fish size and abundance. Groupers and snappers are far less abundant and herbivorous fishes comprise a greater proportion of samples than in the 1960s. Effects of intensive fishing are evident even within MPA boundaries. Although only traditional fishing with traps of 'conventional design' is allowed, commercial trap fishing is occurring. Visual samples of fishes inside and outside Virgin Islands National 'Park showed no significant differences in number of species, biomass, or mean size of fishes. Similarly, the number of fishes per trap was statistically similar inside and outside park waters. These MPAs have not been effective because an unprecedented combination of natural and human factors is assaulting the resources, some of the greatest damage is from stresses outside the control of park managers (e.g. hurricanes), and enforcement of the few regulations has been limited. Fully functioning MPAs which prohibit fishing and other extractive uses (e.g. no-take marine reserves) could reverse some of the degradation, allowing replenishment of the fishery resources and recovery of benthic habitats.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Environmental Conservation","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1017/S0376892901000340","issn":"03768929","usgsCitation":"Rogers, C., and Beets, J., 2001, Degradation of marine ecosystems and decline of fishery resources in marine protected areas in the US Virgin Islands: Environmental Conservation, v. 28, no. 4, p. 312-322, https://doi.org/10.1017/S0376892901000340.","startPage":"312","endPage":"322","numberOfPages":"11","costCenters":[],"links":[{"id":232608,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":207557,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1017/S0376892901000340"}],"volume":"28","issue":"4","noUsgsAuthors":false,"publicationDate":"2002-05-10","publicationStatus":"PW","scienceBaseUri":"5059fe56e4b0c8380cd4eca6","contributors":{"authors":[{"text":"Rogers, C.S. 0000-0001-9056-6961","orcid":"https://orcid.org/0000-0001-9056-6961","contributorId":37274,"corporation":false,"usgs":true,"family":"Rogers","given":"C.S.","affiliations":[],"preferred":false,"id":397739,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Beets, J.","contributorId":95640,"corporation":false,"usgs":true,"family":"Beets","given":"J.","email":"","affiliations":[],"preferred":false,"id":397740,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

Most individuals (97%) of all species except Wilson's Plovers were observed on bayside flats of the barrier islands. Similar numbers of Piping Plovers were recorded at South Padre Island, Texas, and in the Laguna\r\nMadre de Tamaulipas. Over 85% of the individuals of each of the other species were found in the more extensively surveyed Mexico portion of Laguna Madre. In Tamaulipas, most plover species were observed more often on algal flats than any other substrate.

The method is based only on a strong inference that major shifts in paleotemperature recorded at both locations occurred synchronously, consistent with an atmospheric teleconnection.

Indeed, the resulting V-DH chronology is highly correlated with GT4 because of the unexpected correspondence even in the timing of second-order climatic events that were not constrained by the algorithm. Furthermore, the algorithm developed herein is not specific to this problem; rather, the procedure can be used whenever two paleoclimate records are proxies for the same physical phenomenon, and paleoclimatic conditions forcing the two records can be considered to have occurred contemporaneously.

Model calibration was accomplished using data collected from 1981 to 1996 to encompass extreme climatic conditions. Results show that the processes of precipitation largely control wetland stage. Surface runoff produces short duration, high magnitude flows typically associated with spring thaw. On the other hand, groundwater contribution provides flows smaller in magnitude but higher in duration and these become increasingly important with respect to wetland stage during extended periods of drought and flood. Peak groundwater fluxes lag one-to-two months behind peak recharge rates and therefore occur predominantly during the month of June. Groundwater fluxes then attenuate slowly for the remainder of the year to the point where water may move out of the wetland and into the underlying aquifer during the fall and winter months.

Melting of snow during the stopover period causes spatial and temporal variability in distribution and abundance of feeding habitat. We recorded changes in snow cover and lesser snow goose <i>Anser caerulescens caerulescens</i> distribution on a spring migration stopover area in south-central Alaska during aerial surveys in 1993-1994. Our objectives were to determine whether geese selected among areas with different amounts of snow cover and to assess how temporal changes in snow cover affected goose distribution. We also measured temporal changes in chemical composition of forage species after snow melt. We divided an Arc/Info coverage of the approximately 210 km<sup>2</sup> coastal stopover area into 2-km<sup>2</sup> cells, and measured snow cover and snow goose use of cells. Cells that had 10-49.9% snow cover were selected by snow geese, whereas cells that lacked snow cover were avoided. In both years, snow cover diminished along the coast between mid-April and early May. Flock distribution changed as snow geese abandoned snow-free areas in favour of cells where snow patches were interspersed with bare ground. Snow-free areas may have been less attractive to geese because available forage had been quickly exploited as bare ground was exposed, and because soils became drier making extraction of underground forage more difficult. Fiber content of two forage species increased whereas non-structural carbohydrate concentrations of forage plants appeared to diminish after snow melt, but changes in nutrient concentrations likely occurred too slowly to account for abandonment of snow-free areas by snow geese.</p>","language":"English","publisher":"Nordic Council for Wildlife Research ","usgsCitation":"Hupp, J.W., Zacheis, A.B., Anthony, R.M., Robertson, D.G., Erickson, W.P., and Palacios, K.C., 2001, Snow cover and snow goose <i>Anser caerulescens caerulescens</i> distribution during spring migration: Wildlife Biology, v. 7, no. 2, p. 65-76.","productDescription":"12 p.","startPage":"65","endPage":"76","costCenters":[{"id":114,"text":"Alaska Science Center","active":true,"usgs":true}],"links":[{"id":337952,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":337951,"rank":1,"type":{"id":15,"text":"Index Page"},"url":"https://www.wildlifebiology.org/about-journal/journal-information","text":"Journal's Website"}],"country":"United States","state":"Alaska","volume":"7","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"58d23b91e4b0236b68f828fc","contributors":{"authors":[{"text":"Hupp, Jerry W. 0000-0002-6439-3910 jhupp@usgs.gov","orcid":"https://orcid.org/0000-0002-6439-3910","contributorId":127803,"corporation":false,"usgs":true,"family":"Hupp","given":"Jerry","email":"jhupp@usgs.gov","middleInitial":"W.","affiliations":[{"id":117,"text":"Alaska Science Center Biology WTEB","active":true,"usgs":true},{"id":114,"text":"Alaska Science Center","active":true,"usgs":true}],"preferred":true,"id":685408,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Zacheis, Amy B.","contributorId":92460,"corporation":false,"usgs":false,"family":"Zacheis","given":"Amy","email":"","middleInitial":"B.","affiliations":[],"preferred":false,"id":685409,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Anthony, R.

We followed a linked modeling approach that used a specialized reservoir water quality model to forecast operation-induced changes in phytoplankton production. A food web–energy transfer model was also applied to propagate predicted changes in phytoplankton up through the food web to the predators and sport fishes of interest. The food web–energy transfer model employed a 10% trophic transfer efficiency through a food web that was mapped using carbon and nitrogen stable isotope analysis. Stable isotope analysis provided an efficient and comprehensive means of estimating the structure of the reservoir's food web with minimal sampling and background data. We used an optimization procedure to estimate the diet proportions of all food web components simultaneously from their isotopic signatures. Some consumers were estimated to be much more sensitive than others to perturbations to phytoplankton supply. The linked modeling approach demonstrated that interdisciplinary efforts enhance the value of information obtained from studies of managed ecosystems. The approach exploited the strengths of engineering and ecological modeling methods to address concerns that neither of the models could have addressed alone: (a) the water quality model could not have addressed quantitatively the possible impacts to fish, and (b) the food web model could not have examined how phytoplankton availability might change due to reservoir operations.</p>","language":"English","publisher":"Springer","doi":"10.1007/s100210000062","usgsCitation":"Saito, L., Johnson, B., Bartholow, J., and Hanna, R., 2001, Assessing ecosystem effects of reservoir operations using food web-energy transfer and water quality models: Ecosystems, v. 4, no. 2, p. 105-125, https://doi.org/10.1007/s100210000062.","productDescription":"21 p.","startPage":"105","endPage":"125","costCenters":[{"id":291,"text":"Fort Collins Science Center","active":true,"usgs":true}],"links":[{"id":133224,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"4","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4abbe4b07f02db672aa4","contributors":{"authors":[{"text":"Saito, L.","contributorId":59402,"corporation":false,"usgs":true,"family":"Saito","given":"L.","email":"","affiliations":[],"preferred":false,"id":322504,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Johnson, B.

Several additional factors, including species interactions and environmental change, can either mask or intensify the effects of human activity. This study highlights the importance of considering these factors in concert with breeding biology when assessing the impacts of human disturbance on wildlife. We studied the effects of a Wildlife Viewing Area (WVA) at Chatfield State Recreation Area, Colorado, on a nesting colony of great blue herons (</span><i>Ardea herodias</i><span>) and double-crested cormorants (</span><i>Phalacrocorax auritus</i><span>). We stratified the colony's nest trees into near, middle and far areas relative to distances from the WVA and compared the distribution of nests, nesting and fledging success and breeding chronology among areas 2 y before and 2 y after construction of the WVA. We also evaluated whether adult nest attendance patterns and chick behavior differed relative to distance from the WVA. The number of active heron nests and nest success of herons declined during the study, but evidence that these declines were due solely to human disturbance is equivocal. These changes were most likely due to the interplay of habitat changes (loss of 14 of 31 original nest trees by windfall), acquisition of heron nests by cormorants and human disturbance.

These include mathematical deconvolution of chemical analyses, direct microanalysis, sequential extraction procedures and density fractionation. A new methodology combining density fractionation with mathematical deconvolution of chemical analyses of whole coals and their density fractions has been evaluated. These coals formed part of the IEA-Coal Research project on the Modes of Occurrence of Trace Elements in Coal. Results were compared to a previously reported sequential extraction methodology and showed good agreement for most elements. For particular elements (Be, Mo, Cu, Se and REEs) in specific coals where disagreement was found, it was concluded that the occurrence of rare trace element bearing phases may account for the discrepancy, and modifications to the general procedure must be made to account for these.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Fuel","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Elsevier Science Ltd","publisherLocation":"Exeter, United Kingdom","doi":"10.1016/S0016-2361(00)00059-4","issn":"00162361","usgsCitation":"Querol, X., Klika, Z., Weiss, Z., Finkelman, R.B., Alastuey, A., Juan, R., Lopez-Soler, A., Plana, F., Kolker, A., and Chenery, S., 2001, Determination of element affinities by density fractionation of bulk coal samples: Fuel, v. 80, no. 1, p. 83-96, https://doi.org/10.1016/S0016-2361(00)00059-4.","startPage":"83","endPage":"96","numberOfPages":"14","costCenters":[],"links":[{"id":207084,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/S0016-2361(00)00059-4"},{"id":231687,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"80","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059ffa3e4b0c8380cd4f2d4","contributors":{"authors":[{"text":"Querol, X.","contributorId":12340,"corporation":false,"usgs":true,"family":"Querol","given":"X.","email":"","affiliations":[],"preferred":false,"id":400492,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Klika, Z.","contributorId":69431,"corporation":false,"usgs":true,"family":"Klika","given":"Z.","email":"","affiliations":[],"preferred":false,"id":400497,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Weiss, Z.","contributorId":94562,"corporation":false,"usgs":true,"family":"Weiss","given":"Z.","email":"","affiliations":[],"preferred":false,"id":400499,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Finkelman, R.

Results show that for 1980-1996 the mean annual total N flux to the Gulf of Mexico was 1 568 000 t yr-1. The flux was about 61% nitrate N, 37% organic N, and 2% ammonium N. The flux of nitrate N to the Gulf has approximately tripled in the last 30 years with most of the increase occurring between 1970 and 1983. The mean annual N flux has changed little since the early 1980s, but large year-to-year variations in N flux occur because of variations in precipitation. During wet years the N flux can increase by 50% or more due to flushing of nitrate N that has accumulated in the soils and unsaturated zones in the basin. The principal source areas of N are basins in southern Minnesota, Iowa, Illinois, Indiana, and Ohio that drain agricultural land. Basins in this region yield 1500 to more than 3100 kg N km-2 yr-1 to streams, several times the N yield of basins outside this region.","language":"English","publisher":"Wiley","doi":"10.2134/jeq2001.302329x","issn":"00472425","usgsCitation":"Goolsby, D.A., Battaglin, W., Aulenbach, B., and Hooper, R.P., 2001, Nitrogen input to the Gulf of Mexico, v. 30, no. 2, p. 329-336, https://doi.org/10.2134/jeq2001.302329x.","productDescription":"8 p.","startPage":"329","endPage":"336","numberOfPages":"8","costCenters":[{"id":589,"text":"Toxic Substances Hydrology Program","active":true,"usgs":true}],"links":[{"id":232718,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","otherGeospatial":"Mississippi–Atchafalaya River basin","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -92.28515625,\n              46.255846818480315\n            ],\n            [\n              -93.955078125,\n              46.98025235521883\n            ],\n            [\n              -98.173828125,\n              48.3416461723746\n            ],\n            [\n              -101.6015625,\n              48.22467264956519\n            ],\n            [\n              -102.12890625,\n              46.01222384063236\n            ],\n            [\n              -100.107421875,\n              42.94033923363181\n            ],\n            [\n              -97.03125,\n              41.44272637767212\n            ],\n            [\n              -94.306640625,\n              38.61687046392973\n            ],\n            [\n              -93.515625,\n              34.45221847282654\n            ],\n            [\n              -94.39453125,\n              30.221101852485987\n            ],\n            [\n              -92.46093749999999,\n              28.844673680771795\n            ],\n            [\n              -89.6484375,\n              28.844673680771795\n            ],\n            [\n              -88.330078125,\n              30.14512718337613\n            ],\n            [\n              -88.505859375,\n              34.23451236236987\n            ],\n            [\n              -87.451171875,\n              39.57182223734374\n            ],\n            [\n              -85.341796875,\n              39.30029918615029\n            ],\n            [\n              -78.75,\n              39.57182223734374\n            ],\n            [\n              -75.234375,\n              42.09822241118974\n            ],\n            [\n              -75.41015624999999,\n              44.59046718130883\n            ],\n            [\n              -79.1015625,\n              42.94033923363181\n            ],\n            [\n              -82.6171875,\n              41.44272637767212\n            ],\n            [\n              -87.5390625,\n              41.77131167976407\n            ],\n            [\n              -89.296875,\n              43.644025847699496\n            ],\n            [\n              -91.318359375,\n              45.9511496866914\n            ],\n            [\n              -92.28515625,\n              46.255846818480315\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"30","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a66e2e4b0c8380cd73051","contributors":{"authors":[{"text":"Goolsby, D.

The viral DNA loads from tumors obtained from terminal animals were relatively homogenous (range 2a??20 copies/cell), whereas DNA copy numbers from biopsied tumors and skin of otherwise healthy turtles displayed a wide variation (range 0.001a??170 copies/cell) and may reflect the stage of tumor development. FPTHV DNA loads in tumors were 2.5a??4.5 logs higher than in uninvolved skin from the same animal regardless of geographic location, further implying a role for FPTHV in the etiology of fibropapillomatosis.

Here, we review the current understanding of normal and abnormal vertebrate limb development and regeneration and discuss some of the molecular events that may bring about limb malformation. Consideration of the differences between limb development and regeneration in amphibians has led us to the hypothesis that some of the observed limb malformations come about through misdirected regeneration. We report the results of a pilot study that supports this hypothesis. In this study, the distal aspect of the right hindlimb buds of X. laevis tadpoles was amputated at the pre-foot paddle stage. The tadpoles were raised in water from a pond in Minnesota at which 7% of surveyed newly metamorphosed feral frogs had malformations. Six percent (6 of 100) of the right limbs of the tadpoles raised in pond water developed abnormally. One truncated right limb was the only malformation in the control group, which was raised in dechlorinated municipal water. All unamputated limbs developed normally in both groups. Three major factors under consideration for effecting the limb malformations are discussed. These factors include environmental chemicals (primarily agrichemicals), encysted larvae (metacercariae) of trematode parasites, and increased levels of ultraviolet light. Emphasis is placed on the necessary intersection of environmental stressors and developmental events to bring about the specific malformations that are observed in free-living frog populations.</p>","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"The Anatomical Record Part B: The New Anatomist","largerWorkSubtype":{"id":10,"text":"Journal

Model creep is driven by screw dislocations at 12 km depth under the Hayward and other regional faults. Inferred depth to locking varies along strike from 4-12 km. (12 km implies no locking.) Our models require locked patches under the central Hayward fault, consistent with a M6.8 earthquake in 1868, but the geometry and extent of locking under the north and south ends depend critically on assumptions regarding continuity and creep behavior of the fault at its ends. For the northern onshore part of the fault, our models contain 1.4-1.7 times more stored moment than the model of Bu??rgmann et al. [2000]; 45-57% of this stored moment resides in creeping areas. It is important for seismic hazard estimation to know how much of this moment is released coseismically or as aseismic afterslip.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Geophysical Research Letters","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1029/2001GL012979","issn":"00948276","usgsCitation":"Simpson, R., Lienkaemper, J.J., and Galehouse, J., 2001, Variations in creep rate along the Hayward Fault, California, interpreted as changes in depth of creep: Geophysical Research Letters, v. 28, no. 11, p. 2269-2272, https://doi.org/10.1029/2001GL012979.","startPage":"2269","endPage":"2272","numberOfPages":"4","costCenters":[],"links":[{"id":478968,"rank":10000,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1029/2001gl012979","text":"Publisher Index Page"},{"id":207349,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1029/2001GL012979"},{"id":232238,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"28","issue":"11","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505bc17be4b08c986b32a5c4","contributors":{"authors":[{"text":"Simpson, R.W.","contributorId":76738,"corporation":false,"usgs":true,"family":"Simpson","given":"R.W.","email":"","affiliations":[],"preferred":false,"id":397008,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Lienkaemper, J.
