A heavily-explored, geologically well-characterized state, Kansas is an excellent place to study hydrocarbon migration and to test geochemical models for the origin of natural gases. Immature to marginally-mature rocks of eastern Kansas (Cherokee and Forest City basins) produce mixed microbial and thermogenic gases.

Gases from central and western Kansas (Nemaha uplift to Hugoton embayment) are entirely thermogenic and have wetness =4-51%, methane ??13C = -48 to -39??? and methane ??D = -195 to -140???.

Photometric models indicate global average values for regolith porosity of 75-95% and macroscopic roughness with a mean slope angle of ~30??. Abundances of SO2 suggested by observations at uv-visible wavelengths and at 4.08 ??m are partially reconciled by intimate-mixing models; 30-50% SO2 coverage of the integral disk is indicated. Three major spectral end members, with continuous mixing, are recognized from the Voyager multispectral mosaics; one of these end members is identified as SO2. Intimate-mixing models with the three spectal end members are used to produce abundance maps for the optical surface; ~30% of Io's total optical surface consists of SO2. The SO2 is concentrated in the bright equatorial band and is relatively deficient in the region of Pele-type volcanic reuptions (long 240??-360??) and the polar regions. Temperatures are computed to vary over a 40??K range, at the same illumination angle, according to variations in surface bolometric hemispheric albedo. The brightest (and locally coldest) areas correspond to areas rich in SO2 and are concentrated in an equatorial band (??30?? lat), but many small cold patches occur elsewhere. These cold patches have radiative equilibrium temperatures ???120??K at the subsolar point, resulting in SO2 saturation vapor pressures ???10-8 bar. Midlatitude areas and the region of Pele-type plume eruptions are generally warmer (due to lower albedos). These results for surface temperatures and SO2 abundances and distribution support the regional coldtrapping model for the surface and atmospheric SO2 presented by F.P. Fanale, W.B. Banerdt, L.S. Elson, T.V. Johnson, and R.W. Zurek (1982, In Satellites of Jupiter (D.

Matson and D.B. Nash (1983, J. Geophys. Res. 88, 4771-4783). The bright equatorial band is especially effective at slowing the formation of polar caps of SO2, both by reducing the sublimation rate near the subsolar point and by coldtrapping the SO2 in the equatorial region, so that competing processes of sputtering and volcanic resurfacing may prevent the formation of polar SO2 caps.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Icarus","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1016/0019-1035(88)90157-1","issn":"00191035","usgsCitation":"McEwen, A.S., Johnson, T.V., Matson, D.L., and Soderblom, L., 1988, The global distribution, abundance, and stability of SO2 on Io: Icarus, v. 75, no. 3, p. 450-478, https://doi.org/10.1016/0019-1035(88)90157-1.","startPage":"450","endPage":"478","numberOfPages":"29","costCenters":[],"links":[{"id":205665,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/0019-1035(88)90157-1"},{"id":225897,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"75","issue":"3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505bac8ae4b08c986b32357f","contributors":{"authors":[{"text":"McEwen, A.

During 1981 and 1982, accelerating deformation of the crater floor around the vent (including radial cracks, thrust faults, and ground tilt) was the earliest indicator of impending activity. Numerical experiments using the finite element method to model the mechanics of the crater floor show that all deformation features can be explained by a uniform shear-stress boundary condition along the conduit wall. The magnitude of the shear stress required to match observed displacements (1–7 MPa) is inversely proportional to the conduit diameter (estimated to be 25–100 m). The most probable source of this shear stress is the flow of viscous magma up the conduit and into the lava dome. We propose a model in which the accelerating deformation, beginning as much as 4 weeks before extrusions, is caused by the increasing velocity of ascending magma in the conduit. This model is examined by using deformation data of the dome before four extrusions in 1981 and 1982 to estimate the volumetric flow rate through the conduit. This flow rate and an estimate of the effective viscosity of the magma enable calculation of an ascent velocity and an applied shear stress that, again, depend on the conduit diameter. The results of these calculations are consistent with the finite element experiments and show that the proposed model is feasible. In light of this model, events observed just before or near the time extrusions began, such as reversals of ground tilt direction from outward to inward and the sudden decrease in the number of shallow earthquakes, may indicate an abrupt decrease of shear stress in the conduit. This could be explained by a decrease in either the ascent velocity, or the effective viscosity of the magma ascending through the shallow conduit, or both, near the time of extrusion. Precursory deformation like that measured at Mount St. Helens should be observable at similar volcanoes elsewhere because it is caused by the fundamental process of magma ascent.</span></p>","language":"English","publisher":"American Geophysical Union","doi":"10.1029/JB093iB05p04351","issn":"01480227","usgsCitation":"Chadwick, W., Archuleta, R., and Swanson, D.A., 1988, The mechanics of ground deformation precursory to dome-building extrusions at Mount St. Helens 1981-1982: Journal of Geophysical Research Solid Earth, v. 93, no.

The method is designed specifically to account for sampling procedures and uncertainties that are inherent in soil studies. Soil variation and measurement error, uncertainties in calibration dates and their relation to the age of the soil, and the limited number of dated soils are all considered. Maximum likelihood (ML) is employed to estimate a parametric linear calibration curve, relating soil development to time or age on suitably transformed scales. Soil variation on a geomorphic surface of a certain age is characterized by replicate sampling of soils on each surface; such variation is assumed to have a Gaussian distribution. The age of a geomorphic surface is described by older and younger bounds. This technique allows age uncertainty to be characterized by either a Gaussian distribution or by a triangular distribution using minimum, best-estimate, and maximum ages. The calibration curve is taken to be linear after suitable (in certain cases logarithmic) transformations, if required, of the soil parameter and age variables. Soil variability, measurement error, and departures from linearity are described in a combined fashion using Gaussian distributions with variances particular to each sampled geomorphic surface and the number of sample replicates. Uncertainty in age of a geomorphic surface used for calibration is described using three parameters by one of two methods. In the first method, upper and lower ages are specified together with a coverage probability; this specification is converted to a Gaussian distribution with the appropriate mean and variance. In the second method, \"absolute\" older and younger ages are specified together with a most probable age; this specification is converted to an asymmetric triangular distribution with mode at the most probable age. The statistical variability of the ML-estimated calibration curve is assessed by a Monte Carlo method in which simulated data sets repeatedly are drawn from the distributional specification; calibration parameters are reestimated for each such simulation in order to assess their statistical variability. Several examples are used for illustration. The age of undated soils in a related setting may be estimated from the soil data using the fitted calibration curve. A second simulation to assess age estimate variability is described and applied to the examples. ?? 1988 International Association for Mathematical Geology.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Mathematical Geology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisherLocation":"Kluwer Academic Publishers-Plenum Publishers","doi":"10.1007/BF00903188","issn":"08828121","usgsCitation":"Switzer, P., Harden, J., and Mark, R.K., 1988, A statistical method for estimating rates of soil development and ages of geologic deposits: A design for soil-chronosequence studies: Mathematical Geology, v. 20, no. 1, p. 49-61, https://doi.org/10.1007/BF00903188.","startPage":"49","endPage":"61","numberOfPages":"13","costCenters":[],"links":[{"id":226041,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":205676,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1007/BF00903188"}],"volume":"20","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059e5afe4b0c8380cd46f01","contributors":{"authors":[{"text":"Switzer, P.","contributorId":66432,"corporation":false,"usgs":true,"family":"Switzer","given":"P.","email":"","affiliations":[],"preferred":false,"id":369154,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Harden, J.W. 0000-0002-6570-8259","orcid":"https://orcid.org/0000-0002-6570-8259","contributorId":38585,"corporation":false,"usgs":true,"family":"Harden","given":"J.W.","affiliations":[],"preferred":false,"id":369153,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Mark, R.

The results of this modeling effort provide a broad regional perspective on the magnitude and direction of groundwater flow in the confined system in the Coastal Plain physiographic province of southeastern Virginia.","conferenceTitle":"Critical Water Issues and Computer Applications: Proceedings of the 15th Annual Water Resources Conference","conferenceDate":"1 June 1988 through 3 June 1988","conferenceLocation":"Norfolk, VA, USA","language":"English","publisher":"Publ by ASCE","publisherLocation":"New York, NY, United States","isbn":"0872626601","usgsCitation":"Hamilton, P.A., 1988, Regional assessment of pumpage in southeastern Virginia, Critical Water Issues and Computer Applications: Proceedings of the 15th Annual Water Resources Conference, Norfolk, VA, USA, 1 June 1988 through 3 June 1988, p. 168-170.","startPage":"168","endPage":"170","numberOfPages":"3","costCenters":[],"links":[{"id":226077,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"50e4a4aae4b0e8fec6cdbbf2","contributors":{"authors":[{"text":"Hamilton, Pixie A. pahamilt@usgs.gov","contributorId":1068,"corporation":false,"usgs":true,"family":"Hamilton","given":"Pixie","email":"pahamilt@usgs.gov","middleInitial":"A.","affiliations":[],"preferred":true,"id":368060,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

Lead and Sr initial ratios are higher and Nd initial ratios lower than would be expected for rocks derived from model mantle sources and strongly indicate the involvement of an older crustal reservoir in the genesis of these rocks. Crustal contamination during emplacement can be ruled out for a variety of reasons. Instead a model involving subduction of continental detritus and contamination of the overlying mantle as is often proposed for modern subduction environments is preferred. This contaminated mantle would have all the isotopic characteristics of mantle enriched by internal mantle metasomatism but would require no long-term growth or changes in parent to daughter element ratios. This contaminated mantle would make a good source for some of the Cenozoic mafic volcanics of the Columbia River, Snake River Plain, and Yellowstone volcanic fields that are proposed to come from ancient, enriched lithospheric mantle. The isotopic characteristics of the 2.70 Ga old Stillwater Complex are a perfect match for the proposed contaminated mantle which provides an alternative to crustal contamination during emplacement. The Pb isotopic characteristics of the Late Archean rocks of the eastern Beartooth Mountains are similar to those of other Late Archean rocks of the Wyoming Province and suggest that Early Archean, upper crustal rocks were common in this terrane. The isotopic signatures of Late Archean rocks in the Wyoming Province are distinctive from those of other Archean cratons in North America which are dominated by a MORB-like, Archean mantle source (Superior Province) and/or a long-term depleted crustal source (Greenland).</p></div></div></div>","language":"English","publisher":"Elsevier","doi":"10.1016/0012-821X(88)90064-7","issn":"0012821X","usgsCitation":"Wooden, J.L., and Mueller, P., 1988, Pb, Sr, and Nd isotopic compositions of a suite of Late Archean, igneous rocks, eastern Beartooth Mountains: Implications for crust-mantle evolution: Earth and Planetary Science Letters, v. 87, no. 1-2, p. 59-72, https://doi.org/10.1016/0012-821X(88)90064-7.","productDescription":"14 p.","startPage":"59","endPage":"72","numberOfPages":"14","costCenters":[],"links":[{"id":225792,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"87","issue":"1-2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a75fde4b0c8380cd77e6e","contributors":{"authors":[{"text":"Wooden, J.

The study was prompted by a need for an understanding of selenium mobility in areas having high selenium concentrations in shallow groundwater. Groundwater samples were collected along transects in three artificially drained fields where the age of the drainage system varied (15, 6, and 1.5 years). Selenium concentrations in the drain water also varied (430, 58, and 3700 μg/L, respectively). Isotopic enrichment and chemical composition of the groundwater samples indicate that saline- and selenium-enriched water has evolved as a result of evaporation or transpiration of groundwater. This evaporated, isotopically enriched water is being displaced by more recent, less saline irrigation water percolating through the root zone. This displacement seems to be a process whereby sodium chloride and sodium sulfate water is being replaced by more dilute calcium sulfate and calcium bicarbonate water.","language":"English","publisher":"American Geophysical Union","doi":"10.1029/WR024i004p00516","usgsCitation":"Deverel, S.J., and Fujii, R., 1988, Processes affecting the distribution of selenium in shallow groundwater of agricultural areas, western San Joaquin Valley, California: Water Resources Research, v. 24, no. 4, p. 516-524, https://doi.org/10.1029/WR024i004p00516.","productDescription":"9 p.","startPage":"516","endPage":"524","costCenters":[{"id":154,"text":"California Water Science Center","active":true,"usgs":true}],"links":[{"id":225791,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"California","otherGeospatial":"San Joaquin Valley","volume":"24","issue":"4","noUsgsAuthors":false,"publicationDate":"2010-07-09","publicationStatus":"PW","scienceBaseUri":"505a8da9e4b0c8380cd7ed51","contributors":{"authors":[{"text":"Deverel, S.

Variations in Ba, Cr, Ga, Sr, Ti, and V concentrations among the coals were determined using the LAMM A-1000 instrument. LAMMS analysis is not limited to these elements; their selection illustrates the application of the technique. Ba, Cr, Ga, Sr, Ti, and V have minimal site-to-site variance in the vitrinite macerals of the studied coals as measured by LAMMS. The LAMMS data were compared with bulk elemental data obtained by instrumental neutron activation analysis (INAA) and D. C. arc optical emission spectroscopy (DCAS) in order to determine the reliability of the LAMMS data. The complex nature of the ionization phenomena in LAMMS and the lack of standards characterized on a microscale makes obtaining quantitative elemental data within the ionization microvolume difficult; however, we demonstrate that the relative variation of an element among vitrinites from different coal beds in the eastern United States can be observed using LAMMS in a \"bulk\" mode by accumulating signal intensities over several microareas of each vitrinite. Our studies indicate gross changes (greater than a factor of 2 to 5 depending on the element) can be monitored when the elemental concentration is significantly above the detection limit. \"Bulk\" mode analysis was conducted to evaluate the accuracy of future elemental LAMMS microanalyses. The primary advantage of LAMMS is the inherent spatial resolution, ~ 20 ??m for coal. Two different vitrite bands in the Lower Bakerstown coal bed (CLB-1) were analyzed. The analysis did not establish any certain concentration differences in Ba, Cr, Ga, Sr, Ti, and V between the two bands. ?? 1988 Springer-Verlag.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Mikrochimica Acta","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisherLocation":"Springer-Verlag","doi":"10.1007/BF01236096","issn":"00263672","usgsCitation":"Morelli, J., Hercules, D., Lyons, P., Palmer, C., and Fletcher, J., 1988, Using laser micro mass spectrometry with the LAMMA-1000 instrument for monitoring relative elemental concentrations in vitrinite: Mikrochimica Acta, v. 96, no. 1-6, p. 105-118, https://doi.org/10.1007/BF01236096.","startPage":"105","endPage":"118","numberOfPages":"14","costCenters":[],"links":[{"id":205644,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1007/BF01236096"},{"id":225655,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"96","issue":"1-6","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505bc066e4b08c986b32a0de","contributors":{"authors":[{"text":"Morelli, J.J.","contributorId":90891,"corporation":false,"usgs":true,"family":"Morelli","given":"J.J.","email":"","affiliations":[],"preferred":false,"id":369065,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Hercules, D.M.","contributorId":86905,"corporation":false,"usgs":true,"family":"Hercules","given":"D.M.","email":"","affiliations":[],"preferred":false,"id":369063,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Lyons, P.C.","contributorId":87285,"corporation":false,"usgs":true,"family":"Lyons","given":"P.C.","email":"","affiliations":[],"preferred":false,"id":369064,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Palmer, C.A.","contributorId":81894,"corporation":false,"usgs":true,"family":"Palmer","given":"C.A.","email":"","affiliations":[],"preferred":false,"id":369062,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Fletcher, J.D.","contributorId":24928,"corporation":false,"usgs":true,"family":"Fletcher","given":"J.D.","email":"","affiliations":[],"preferred":false,"id":369061,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}}

The hourly range R was recommended by IAGA for use at observatories at latitudes greater than 65??, but was superceded by AE. The most used geomagnetic index K is based on the range of activity in a 3 h interval corrected for the regular daily variation. In order to take advantage of real time data processing, now available at many observatories, it is proposed to introduce a 1 h range index and also a 3 h range index. Both will be computed hourly, i.e. each will have a series of 24 per day, the 3 h values overlapping. The new data will be available as the range (R) of activity in nT and also as a logarithmic index (I) of the range. The exponent relating index to range in nT is based closely on the scale used for computing K values. The new ranges and range indices are available, from June 1987, to users in real time and can be accessed by telephone connection or computer network. Their first year of production is regarded as a trial period during which their value to the scientific and commercial communities will be assessed, together with their potential as indicators of regional and global disturbances' and in which trials will be conducted into ways of eliminating excessive bias at quiet times due to the rate of change of the daily variation field. ?? 1988.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Atmospheric and Terrestrial Physics","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Elsevier","doi":"10.1016/0021-9169(88)90107-9","issn":"00219169","usgsCitation":"Stuart, W., and Green, A., 1988, Range indices of geomagnetic activity: Journal of Atmospheric and Terrestrial Physics, v. 50, no. 6, p. 501-506, https://doi.org/10.1016/0021-9169(88)90107-9.","startPage":"501","endPage":"506","numberOfPages":"6","costCenters":[],"links":[{"id":220277,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":268033,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/0021-9169(88)90107-9"}],"volume":"50","issue":"6","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a94a2e4b0c8380cd81515","contributors":{"authors":[{"text":"Stuart, W.F.","contributorId":84835,"corporation":false,"usgs":true,"family":"Stuart","given":"W.F.","email":"","affiliations":[],"preferred":false,"id":366868,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Green, A.W.

Together, these processes play a major role in changing the configuration of the estuary and filling it with sediment. The deposits at the mouth of the bay hold keys both to the evolution of the bay during the Holocene transgression and to the history of previous generations of the bay.</div><div class=\"u-margin-s-bottom\">The deposit associated with the shoals at the mouth of the bay, the bay-mouth sand, is a distinct stratigraphic unit composed mostly of uniform, gray, fine sand. The position and internal structure of the unit shows that it is related to near-present sea level, and thus is less than a few thousand years old. The processes affecting the upper surface of the deposit and the patterns of erosion and deposition at this surface are complex, but the geometry and structure of the deposit indicate that it is a coherent unit that is prograding bayward and tending to fill the estuary.</div><div class=\"u-margin-s-bottom\">The source of the bay-mouth sand is primarily outside the bay in the nearshore zone of the Delmarva Peninsula and on the inner continental shelf. The internal structure of the deposit, its surface morphology, its heavy-mineral composition, bottom-current studies, comparative bathymetry, and sediment budgets all suggest that sand is brought to the bay mouth by southerly longshore drift along the Delmarva Peninsula and then swept into the bay. In addition to building the southward- and bayward-prograding bay-mouth sand, these processes result in sand deposition tens of kilometers into the bay.</div></div></div></div></div><div id=\"preview-section-introduction\"><br></div>","language":"English","publisher":"Elsevier","doi":"10.1016/0025-3227(88)90054-0","issn":"00253227","usgsCitation":"Colman, S.M., Berquist, C.R., and Hobbs, C.H., 1988, Structure, age and origin of the bay-mouth shoal deposits, Chesapeake Bay, Virginia: Marine Geology, v. 83, no. 1-4, p. 95-113, https://doi.org/10.1016/0025-3227(88)90054-0.","productDescription":"19 p.","startPage":"95","endPage":"113","numberOfPages":"19","costCenters":[],"links":[{"id":220560,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"83","issue":"1-4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505b9c66e4b08c986b31d3e5","contributors":{"authors":[{"text":"Colman, Steven M. 0000-0002-0564-9576","orcid":"https://orcid.org/0000-0002-0564-9576","contributorId":77482,"corporation":false,"usgs":true,"family":"Colman","given":"Steven","email":"","middleInitial":"M.","affiliations":[{"id":678,"text":"Woods Hole Coastal and Marine Science Center","active":true,"usgs":true}],"preferred":false,"id":366904,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Berquist, C.

This finding is consistent with earlier findings of Savage (1971) for a relatively few large earthquakes along the west coast of North America, and of Wood and Allen (1973) for smaller events along the San Andreas fault in central California. The average speed of migration is approximately 130 km/yr, which is within the range of speeds observed for other major seismic zones in the world. The epicenter migration in California may be the result of some small but broad-scaled episodic strain changes associated with creep waves induced by magma injections at the East Pacific Rise and propagating northwestwardly along a broad transform boundary between the Pacific and North American plates at subseismogenic depths as proposed by Savage (1971). ?? 1988 Birkha??user Verlag.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Pure and Applied Geophysics PAGEOPH","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisherLocation":"Birkha??user-Verlag","doi":"10.1007/BF00881748","issn":"00334553","usgsCitation":"King, C., and Ma, Z., 1988, Migration of historical earthquakes in California: Pure and Applied Geophysics PAGEOPH, v. 127, no. 4, p. 627-639, https://doi.org/10.1007/BF00881748.","startPage":"627","endPage":"639","numberOfPages":"13","costCenters":[],"links":[{"id":205020,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1007/BF00881748"},{"id":220236,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"127","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a5708e4b0c8380cd6d9df","contributors":{"authors":[{"text":"King, C.-Y.","contributorId":81225,"corporation":false,"usgs":true,"family":"King","given":"C.-Y.","affiliations":[],"preferred":false,"id":365449,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Ma, Z.","contributorId":25288,"corporation":false,"usgs":true,"family":"Ma","given":"Z.","email":"","affiliations":[],"preferred":false,"id":365448,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}
