Based on lithology and stratigraphy, depositional sequences are defined, and calcareous nannofossil zones and 87Sr/86Sr ratios and corresponding ages using the LOWESS Table determined. Campanian and Maastrichtian sediments comprise six depositional sequences. The oldest is Tar Heel 1 and contains calcareous nannofossils that indicate assignment to the upper part of Zones CC18a, CC18c and the lower part of CC19. 87Sr/86 Sr ratios indicate ages from 83.2 to 80.0 Ma or lower Campanian. Tar Heel II contains calcareous nannofossils that indicate assignment to the upper part of Zone CC 19 and CC20. 87Sr/86Sr ratios indicate ages from 78.0 to 76.3 Ma or middle Campanian. Donoho Creek I and II are thin and contain calcareous nannofossils referable to upper Zone CC21 and Zone CC22, and to CC23, respectively. The top of Donoho Creek II marks the Campanian-Maastrichtian boundary. Donoho Creek I 87Sr/86Sr ratios cluster into two groups, and provide ages from 78.0 to 76.2 Ma and 73.7 to 72.3 Ma, respectively. 87Sr/86Sr ratios in Donoho Creek II indicate ages from 71.4 to 69.6 Ma. Two Maastrichtian sequences are present; the lowermost Peedee I contains calcareous nannofossils that place it in Zones CC25a and CC25b. 87Sr/86Sr r ratios indicate an age from 69.3 to 66.9 Ma or late Maastrichtian. Peedee II is assigned to calcareous nannofossil Zone CC26a. 87Sr/86Sr ratios indicate ages from 66.4 to 65.2 Ma or late Maastrichtian. The four Campanian sequences correlate to three depositional sequences in New Jersey; the sequence boundary between upper Campanian Donoho Creek I and Donoho Creek II is not recognized in New Jersey. This boundary is interpreted to result from Gulf Stream impingement and subsequent erosion on the outer shelf. The two Maastrichtian sequences recognized in the Kure Beach core correlate to the two identified Maastrichtian sequences in New Jersey. These data support base-level lowering of sea-level during the Campanian-Maastrichtian, and suggest that the western margin of the North Atlantic may contain one of the best Late Cretaceous records of sea-level change.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Stratigraphy","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","issn":"00262803","usgsCitation":"Harris, W., and Self-Trail J.M., 2006, Late Cretaceous base level lowering in Campanian and Maastrichtian depositional sequences, Kure Beach, North Carolina: Stratigraphy, v. 3, no. 3, p. 195-216.","startPage":"195","endPage":"216","numberOfPages":"22","costCenters":[],"links":[{"id":236711,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"3","issue":"3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a44d4e4b0c8380cd66e07","contributors":{"authors":[{"text":"Harris, W.B.","contributorId":6635,"corporation":false,"usgs":true,"family":"Harris","given":"W.B.","email":"","affiliations":[],"preferred":false,"id":418848,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Self-Trail J.M.","contributorId":128180,"corporation":true,"usgs":false,"organization":"Self-Trail J.M.","id":535156,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

Herein we show that increasing MR flow is mainly in its baseflow as a result of land use change and accompanying agricultural activities that occurred in the MR basin during the last 60 years. Agricultural land use change in the MR basin has affected the basin-scale hydrology: more precipitation is being routed into streams as baseflow than stormflow since 1940 s. We explain that the conversion of perennial vegetation to seasonal row crops, especially soybeans, in the basin since 1940 s may have reduced evapotranspiration, increased groundwater recharge, and thus increased baseflow and streamflow. This explanation is supported with a data analysis of the annually and monthly flow rates at various river stations in the MR basin. Results from this study will help to direct our effort in managing land use and in reducing nutrient levels in MR and other major rivers since nutrient concentrations and loads carried by storm water and baseflow are different. ?? 2005 Elsevier B.V.

Several previous studies have addressed how these thick sediments might modify probabilistic seismic-hazard maps. The high seismic hazard associated with the New Madrid seismic zone makes it particularly important to quantify the uncertainty in modeling site amplification to better represent earthquake hazard in seismic-hazard maps. The methodology of the Memphis urban seismic-hazard-mapping project (Cramer et al., 2004) is combined with the reference profile approach of Toro and Silva (2001) to better estimate seismic hazard in the Mississippi embayment. Improvements over previous approaches include using the 2002 national seismic-hazard model, fully probabilistic hazard calculations, calibration of site amplification with improved nonlinear soil-response estimates, and estimates of uncertainty. Comparisons are made with the results of several previous studies, and estimates of uncertainty inherent in site-amplification modeling for the upper Mississippi embayment are developed. I present new seismic-hazard maps for the upper Mississippi embayment with the effects of site geology incorporating these uncertainties.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Bulletin of the Seismological Society of America","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1785/0120060037","issn":"00371106","usgsCitation":"Cramer, C., 2006, Quantifying the uncertainty in site amplification modeling and its effects on site-specific seismic-hazard estimation in the upper Mississippi embayment and adjacent areas: Bulletin of the Seismological Society of America, v. 96, no. 6, p. 2008-2020, https://doi.org/10.1785/0120060037.","startPage":"2008","endPage":"2020","numberOfPages":"13","costCenters":[],"links":[{"id":209604,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1785/0120060037"},{"id":236258,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"96","issue":"6","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a91eee4b0c8380cd8054d","contributors":{"authors":[{"text":"Cramer, C.H.","contributorId":100012,"corporation":false,"usgs":true,"family":"Cramer","given":"C.H.","email":"","affiliations":[],"preferred":false,"id":419284,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

We used a 300-m-wide strip transect to estimate seabird density, and we estimated relative abundance of birds at all distances. In 2001, we observed a total of 326 birds of 18 species. The mean relative abundance of all birds was 14.3 ?? 3.1/h. Red-footed Booby Sula sula was the most abundant species (5.6/h), followed by White Tern Gygis alba (3.4/h), and Great Crested or Swift Tern Sterna bergii (1.2/h). In 2003, we observed a total of 1463 birds of 25 species. The mean relative abundance of all birds was 36.6 ?? 11.4/h and the mean density of all birds was 4.14 ?? 0.72/km2. Brown Noddy Anous stolidus was the most abundant species (17.6/h, 1.5/km2), followed by White Tern (8.4/h, 1.3/km2), and Red-footed Booby (4.6/h, 0.8/km2). Several globally or locally rare species were observed infrequently, including Phoenix Petrel Pterodroma alba (0.1/h, 0.03/km2). Distribution of birds was uneven, with long periods of no birds punctuated by occasional feeding flocks. In 2003, species diversity was related to length of observation period, with more species observed on longer segments (r2 = 0.58, F1.5 = 6.03, P = 0.05).

These participants included 173 people from the USA, of whom forty-two represented the US Geological Survey (USGS). Fourteen of the US State geological surveys sent representatives to Washington. Eight participants came from other countries in the Western Hemisphere - Canada (3), Chile (1), Mexico (3), and Peru (1). The sixty-six European geologists and naturalists at the 5th IGC represented Austro-Hungary (3), Belgium (3), Britain (12), France (7), Germany (23), Norway (1), Romania (3), Russia (8), Sweden (4), and Switzerland (2). The USGS and the Columbian College (now the George Washington University) acted as the principal hosts. The American Association for the Advancement of Science and then the Geological Society of America (GSA) met in the Capital immediately before the Congress convened (26 August-1 September 1891). The 5th IGC's formal discussions treated the genetic classification of Pleistocene rocks, the chronological correlation of clastic rocks, and the international standardization of colors, symbols, and names used on geologic maps. The third of those topics continued key debates at the 1st through 4th IGCs. The GSA, the Korean Embassy, the Smithsonian Institution's US National Museum, the USGS, and one of the two Secretaries-General hosted evening receptions. Field excursions examined Paleozoic exposures in New York (18-25 August), Cretaceous-Pleistocene localities along the Potomac River south of Washington (30 August), and classic Precambrian-Pleistocene sequences and structures in the Great Plains, Yellowstone, Rocky Mountains, and Great Basin (2-26 September), with optional trips to the Grand Canyon (19-28 September) and Lake Superior (23 September-2 October).

In disciplines ranging from astronomy to chemistry, spectroscopic measurements are used to detect absorption and emission features due to specific chemical bonds, and detailed analyses are used to determine the abundance and physical state of the detected absorbing/emitting species. Spectroscopic measurements have a long history in the study of the Earth and planets. Up to the 1990s remote spectroscopic measurements of Earth and planets were dominated by multispectral imaging experiments that collect high-quality images in a few, usually broad, spectral bands or with point spectrometers that obtained good spectral resolution but at only a few spatial positions. However, a new generation of sensors is now available that combines imaging with spectroscopy to create the new discipline of imaging spectroscopy. Imaging spectrometers acquire data with enough spectral range, resolution, and sampling at every pixel in a raster image so that individual absorption features can be identified and spatially mapped (Goetz et al., 1985).","largerWorkTitle":"International Geoscience and Remote Sensing Symposium (IGARSS)","conferenceTitle":"2006 IEEE International Geoscience and Remote Sensing Symposium, IGARSS","conferenceDate":"31 July 2006 through 4 August 2006","conferenceLocation":"Denver, CO","language":"English","doi":"10.1109/IGARSS.2006.514","isbn":"0780395107; 9780780395107","usgsCitation":"Clark, R.N., Boardman, J., Mustard, J., Kruse, F., Ong, C., Pieters, C., and Swayze, G., 2006, Mineral mapping and applications of imaging spectroscopy, <i>in</i> International Geoscience and Remote Sensing Symposium (IGARSS), Denver, CO, 31 July 2006 through 4 August 2006, p. 1986-1989, https://doi.org/10.1109/IGARSS.2006.514.","startPage":"1986","endPage":"1989","numberOfPages":"4","costCenters":[],"links":[{"id":209866,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1109/IGARSS.2006.514"},{"id":236607,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a5797e4b0c8380cd6dd89","contributors":{"authors":[{"text":"Clark, R.

Each time a major unconformity was developed between the surface exposed beneath the slides and the much younger rocks deposited after the slope failures. The first slope-failure event took place between the late Early Silurian and the end of the Late Silurian when much of the upper member of the Late Ordovician-Early Silurian Ely Springs Dolomite was detached and displaced as a coherent slab ???1 km down slope. The second event occurred in the Middle Devonian when rocks of the Ely Springs Dolomite were again detached, this time forming a rockslide that traveled about 10km down slope to the northwest where it was deposited as a chaotic breccia >250m thick. These events took place as the region was undergoing substantial geomorphic change. The first detachment resulted from an abrupt steepening of the slope, an event previously recognized as having occurred all along the continental margin from eastern California to central Idaho. The second event probably was triggered by a pronounced drop in sea level on the already rather steep slope. At least one similar detachment resulting in an unconformity has been recognized along the middle Paleozoic margin in central Nevada. Recognition of these slope-failure events in an area of unusually complete exposure of middle Paleozoic slope deposits provides an excellent example of a mechanism other than submarine erosion or nondeposition to explain the development of unconformities in ancient slope sequences.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Stratigraphy","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","issn":"00262803","usgsCitation":"Stevens, C., and Stone, P., 2006, Submarine gravity slides on the Paleozoic continental slope at the western edge of the Great Basin, east-cental California: A mechanism for development of unconformities in slope environments: Stratigraphy, v. 3, no. 2, p. 139-149.","startPage":"139","endPage":"149","numberOfPages":"11","costCenters":[],"links":[{"id":236257,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"3","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505b9d25e4b08c986b31d680","contributors":{"authors":[{"text":"Stevens, C.H.","contributorId":16102,"corporation":false,"usgs":true,"family":"Stevens","given":"C.H.","affiliations":[],"preferred":false,"id":419282,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Stone, P.","contributorId":93632,"corporation":false,"usgs":true,"family":"Stone","given":"P.","email":"","affiliations":[],"preferred":false,"id":419283,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

With an accurate function of postseismic response, the coseismic displacements can be estimated from the high-rate, 1-min sampling GPS; and the coseismic displacements are approximately 75% of those estimated from the daily solutions. Consequently, fault-slip models using daily solutions overestimate coseismic slip. In addition, at 2 months and at 8 months following the mainshock, postseismic displacements are modeled as slip on the San Andreas fault with a lower bound on the moment exceeding that of the coseismic moment.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Bulletin of the Seismological Society of America","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1785/0120050823","issn":"00371106","usgsCitation":"Langbein, J., Murray, J., and Snyder, H.A., 2006, Coseismic and initial postseismic deformation from the 2004 Parkfield, California, earthquake, observed by global positioning system, electronic distance meter, creepmeters, and borehole strainmeters: Bulletin of the Seismological Society of America, v. 96, no. 4 B, https://doi.org/10.1785/0120050823.","costCenters":[],"links":[{"id":209731,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1785/0120050823"},{"id":236428,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"96","issue":"4 B","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059fc5ae4b0c8380cd4e237","contributors":{"authors":[{"text":"Langbein, J.","contributorId":16990,"corporation":false,"usgs":true,"family":"Langbein","given":"J.","affiliations":[],"preferred":false,"id":418604,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Murray, J.R.","contributorId":39179,"corporation":false,"usgs":true,"family":"Murray","given":"J.R.","email":"","affiliations":[],"preferred":false,"id":418605,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Snyder, Hollice A.","contributorId":59530,"corporation":false,"usgs":true,"family":"Snyder","given":"Hollice","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":418606,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

In previous work, we developed techniques to automatically correct the alignment of vector data with orthoimagery using a technique called conflation. However, in applying our technique to real-world datasets provided by USGS, we discovered that these techniques failed in some areas. In this paper, we describe some refinements to our original approach that provide consistently better results in aligning the vector data with the orthoimagery.","largerWorkTitle":"ACM International Conference Proceeding Series","conferenceTitle":"7th Annual International Conference on Digital Government Research, Dg.o 2006","conferenceDate":"21 May 2006 through 24 May 2006","conferenceLocation":"San Diego, CA","language":"English","doi":"10.1145/1146598.1146680","usgsCitation":"Knoblock, C., Shahabi, C., Chen, C., and Usery, E., 2006, Automatic alignment of vector data and orthoimagery for the national map, <i>in</i> ACM International Conference Proceeding Series, v. 151, San Diego, CA, 21 May 2006 through 24 May 2006, p. 303-304, https://doi.org/10.1145/1146598.1146680.","startPage":"303","endPage":"304","numberOfPages":"2","costCenters":[],"links":[{"id":236783,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":209997,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1145/1146598.1146680"}],"volume":"151","noUsgsAuthors":false,"publicationDate":"2006-05-21","publicationStatus":"PW","scienceBaseUri":"5059eef8e4b0c8380cd4a094","contributors":{"authors":[{"text":"Knoblock, C.A.","contributorId":105107,"corporation":false,"usgs":true,"family":"Knoblock","given":"C.A.","email":"","affiliations":[],"preferred":false,"id":419281,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Shahabi, C.","contributorId":51521,"corporation":false,"usgs":true,"family":"Shahabi","given":"C.","email":"","affiliations":[],"preferred":false,"id":419280,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Chen, C.-C.","contributorId":22559,"corporation":false,"usgs":true,"family":"Chen","given":"C.-C.","email":"","affiliations":[],"preferred":false,"id":419278,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Usery, E.L.","contributorId":45355,"corporation":false,"usgs":true,"family":"Usery","given":"E.L.","email":"","affiliations":[],"preferred":false,"id":419279,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

Core sites were chosen to reflect a matrix of variable water depths, proximity to the Mississippi River mouth as the primary source for terrigenous particles, and extent and duration of summertime water column hypoxia. The vertical distribution of 239,240Pu and 210Pbxs (= 210Pbtotal - 226Ra) provided reliable geochronological age constraints to develop models for mass accumulation rates and historic trace element inputs and variations. Mass accumulation rates ranged from 0.27 to 0.87 g cm-2 yr-1 and were internally consistent using either 210Pbxs or 239,240Pu. Measured inventories of 137Cs, 239,240Pu, and 210Pbxs were compared to atmospheric deposition rates to quantify potential sediment focusing or winnowing. Observed variability in calculated mass accumulation rates may be attributed foremost to site-specific proximity to the river mouth (i.e., sediment source), variability in water depth, and enhanced sediment focusing at the Mississippi River canyon site. Trace element concentrations were first normalized to Al, and then Al-normalized enrichment factors (ANEF) were calculated based on preanthropogenic and crustal trace element abundances. These ANEFs were typically > 1 for V and Ba, while for most other elements studied, either no enrichment or depletion was observed. The enrichment of Ba may be related, in part, to the seasonal occurrence of oxygen-depleted subsurface waters off the Mississippi River delta, as well as being an ubiquitous by-product of the petroleum industry. ?? 2006 Estuarine Research Federation.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Estuaries and Coasts","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","issn":"15592723","usgsCitation":"Swarzenski, P., Baskaran, M., Rosenbauer, R., and Orem, W., 2006, Historical trace element distribution in sediments from the Mississippi River delta: Estuaries and Coasts, v. 29, no. 6 B, p. 1094-1107.","startPage":"1094","endPage":"1107","numberOfPages":"14","costCenters":[],"links":[{"id":236603,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"29","issue":"6 B","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a31a2e4b0c8380cd5e0c1","contributors":{"authors":[{"text":"Swarzenski, P.W. 0000-0003-0116-0578","orcid":"https://orcid.org/0000-0003-0116-0578","contributorId":29487,"corporation":false,"usgs":true,"family":"Swarzenski","given":"P.W.","affiliations":[],"preferred":false,"id":418808,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Baskaran, M.","contributorId":96627,"corporation":false,"usgs":true,"family":"Baskaran","given":"M.","affiliations":[],"preferred":false,"id":418811,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Rosenbauer, R.J.","contributorId":37320,"corporation":false,"usgs":true,"family":"Rosenbauer","given":"R.J.","email":"","affiliations":[],"preferred":false,"id":418809,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Orem, W.

These three sensors are used together to provide images with different resolution and coverage. To understand the absolute radiometric calibration accuracy of IRS-P6 AWiFS and LISS-III sensors, image pairs from these sensors were compared to the Landsat-5 TM and Landsat-7 ETM+ sensors.

Grand canonical Monte Carlo simulation of nitrogen adsorption on localized sites of a bundle is carried out to predict adsorption in its accessible internal pore volume and on its external surface as a function of tube diameter. External adsorption is split into the contributions from the clean surface of the outermost nanotubes of the bundle and from the surface of the impurities. The site-specific isotherms are then combined into a global isotherm for a given sample using knowledge of its tube-diameter distribution obtained by Raman spectroscopy. The structural parameters of the sample, such as the fraction of open-ended nanotubes and the contributions from impurities and nanotube bundles to total external surface area, are determined by fitting the experimental nitrogen adsorption data to the simulated isotherm. The degree of closure between experimental and calculated adsorption isotherms for samples manufactured by two different methods, to provide different nanotube morphology and contamination level, further strengthens the validity and resulting interpretations based on the proposed approach. The average number of nanotubes per bundle and average bundle size, within a sample, are also quantified. The proposed method allows for extrapolation of adsorption properties to conditions where the purification process is 100% effective at removing all impurities and opening access to all intrabundle adsorption sites. ?? 2006 Elsevier Ltd.

Recent extreme weather (hurricanes Katrina and Rita), extremely destructive international earthquakes (in Sumatra and Pakistan), and nation-wide concerns regarding future terrorist attacks have increased the pressure on utilities to take appropriate steps to avoid being overwhelmed by such infrequent and exceedingly severe events. Determining what constitutes the appropriate steps to take requires various levels of understanding of the specific hazards and the risks faced by the utility. The American Lifelines Alliance (www. americanlifelinesalliance.org) has prepared a Guideline that provides clear, concise, and nationally-applicable guidance on determining the scope and level of effort necessary to assess power system performance in the wide range of natural hazard or human threat events. Included in this Guideline are specific procedures to follow and information to consider in performing standardized assessments. With the results of such assessments, utility owners can effectively establish and carry out risk management programs that will lead to achieving appropriate levels of performance in future events. The Guideline incorporates an inquiry-driven process with a two-phase performance assessment that can be applied to power systems of any size. The screening phase enables systems or components that are clearly not at risk to be screened out early. The subsequent analysis phase uses results from the screening phase to prioritize and allocate resources for more detailed assessments of hazard, vulnerability, and system performance. This process helps assure that the scope of the assessment meets the specific performance objectives of the inquiry. A case history is presented to illustrate the type of experience with an inquiry-driven process that was considered in developing the Guideline to meet the diverse needs of utility personnel in engineering, operations, and management.

All rock samples show 234U depletion relative to parent 238U indicating varying degrees of water-rock interaction over the past million years. Variations in 234U/238U activity ratios indicate that depletion of 234U relative to 238U can be either smaller or greater in rock beneath cavity floors relative to rock near cavity margins. These results are consistent with the concept of drift shadow and with numerical simulations of meter-scale spherical cavities in fractured tuff. Differences in distribution patterns of 234U/ 238U activity ratios in rock beneath the cavity floors are interpreted to reflect differences in the amount of past seepage into lithophysal cavities, as indicated by the abundance of secondary mineral deposits present on the cavity floors.","largerWorkTitle":"Proceedings of the 11th International High Level Radioactive Waste Management Conference, IHLRWM","conferenceTitle":"11th International High Level Radioactive Waste Management Conference","conferenceDate":"30 April 2006 through 4 May 2006","conferenceLocation":"Las Vegas, NV","language":"English","isbn":"0894486918; 9780894486913","usgsCitation":"Paces, J., Neymark, L., Ghezzehei, T., and Dobson, P., 2006, Testing the concept of drift shadow at Yucca Mountain, Nevada, <i>in</i> Proceedings of the 11th International High Level Radioactive Waste Management Conference, IHLRWM, v. 2006, Las Vegas, NV, 30 April 2006 through 4 May 2006, p. 278-285.","startPage":"278","endPage":"285","numberOfPages":"8","costCenters":[],"links":[{"id":236249,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"2006","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505ba5d2e4b08c986b320cdb","contributors":{"authors":[{"text":"Paces, J.B. 0000-0002-9809-8493","orcid":"https://orcid.org/0000-0002-9809-8493","contributorId":27482,"corporation":false,"usgs":true,"family":"Paces","given":"J.B.","affiliations":[],"preferred":false,"id":418575,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Neymark, L.A. 0000-0003-4190-0278","orcid":"https://orcid.org/0000-0003-4190-0278","contributorId":56673,"corporation":false,"usgs":true,"family":"Neymark","given":"L.A.","affiliations":[],"preferred":false,"id":418576,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Ghezzehei, T.","contributorId":86160,"corporation":false,"usgs":true,"family":"Ghezzehei","given":"T.","affiliations":[],"preferred":false,"id":418578,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Dobson, P.F.","contributorId":68466,"corporation":false,"usgs":true,"family":"Dobson","given":"P.F.","email":"","affiliations":[],"preferred":false,"id":418577,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

Earth sciences employ a strongly visual approach to the measurement and analysis of geologic data due to the spatial and temporal scales over which such data ranges, As observations and simulations increase in size and complexity, the Earth sciences are challenged to manage and interpret increasing amounts of data. Reaping the full intellectual benefits of immersive VR requires us to tailor exploratory approaches to scientific problems.

We investigated species-habitat relationships that predict H. scutatum nesting presence in Maine at wetland and microhabitat scales by comparing microhabitats with and without nests. We created logistic regression models, selected models with AIC, and evaluated models with reserve data. Wetlands with nests were best predicted by shoreline microhabitat of Sphagnum spp., wood substrate, water flow, blue-joint reed grass (Calamagrostis canadensis), meadowsweet (Spiraea alba), steeplebush (Spiraea tomentosa), sensitive fern (Onoclea sensibilis), and absence of sheep laurel (Kalmia angustifolia) or deciduous forest canopy. Within occupied wetlands, shoreline microhabitat where nests occurred was best distinguished from available, unoccupied shoreline microhabitat by steeper shore, greater near-shore and basin water depth, deeper nesting vegetation, presence of moss spp. and winterberry (Ilex verticillata), and a negative association with S. alba, leatherleaf (Chamaedaphne calyculata), and K. angustifolia. These models of wetland and microhabitat use by H. scutatum may assist ecologists and managers in detecting and conserving this species.

Layer charge and charge distribution were determined by XRD using the LayerCharge program [Christidis, G.E., Eberl, D.D., 2003. Determination of layer charge characteristics of smectites. Clays Clay Miner. 51, 644-655.]. The rheological properties were determined, after sodium exchange using the optimum amount of Na2CO3, from free swelling tests. Rheological properties were determined using 6.42% suspensions according to industrial practice. In smectites with layer charges of - 0.425 to - 0.470 per half formula unit (phfu), layer charge is inversely correlated with free swelling, viscosity, gel strength, yield strength and thixotropic behaviour. In these smectites, the rheological properties are directly associated with the proportion of low charge layers. By contrast, in low charge and high charge smectites there is no systematic relation between layer charge or the proportion of low charge layers and rheological properties. However, low charge smectites yield more viscous suspensions and swell more than high charge smectites. The rheological properties of bentonites also are affected by the proportion of tetrahedral charge (i.e. beidellitic charge), by the existence of fine-grained minerals having clay size, such as opal-CT and to a lesser degree by the ionic strength and the pH of the suspension. A new method for classification of smectites according to the layer charge based on the XRD characteristics of smecites is proposed, that also is consistent with variations in rheological properties. In this classification scheme the term smectites with intermediate layer charge is proposed. ?? 2006 Elsevier B.V.

Model boundary conditions were modified to reflect the implementation of three major river rehabilitation strategies being considered in the Sacramento River Valley: gravel augmentation, setting back of levees, and flow alteration. Fifty 30‐year model simulations were used to compute probabilities of the response in sediment flux and net storage to these strategies. Total annual average bed material sediment flux estimates were made at six gauged river cross sections, and ∼60 km reach‐scale sediment budgets were evaluated between them. Gravel augmentation to improve spawning habitat induced gravel accumulation locally and/or downstream, depending on the added mixture. Levee setbacks to recreate the river corridor reduced flow stages for most flows and hence lowered sediment flux. Flow alteration to mimic natural flow regimes systematically decreased total annual average flux, suggesting that high‐magnitude low‐frequency transport events do not affect long‐term trends in bed material flux. The results indicate that each rehabilitation strategy reduces sediment transport in its target reaches and modulates imbalances in total annual bed material sediment budgets at the reach scale. Additional risk analysis is necessary to identify extreme conditions associated with variable hydrology that could affect rehabilitation over decades. Sensitivity analysis suggests that sorting of bed material sediment is the most important determinant of modeled transport and storage patterns.</span></p>","language":"English","publisher":"American Geophysical Union","doi":"10.1029/2006WR004894","usgsCitation":"Singer, M.B., and Dunne, T., 2006, Modeling the influence of river rehabilitation scenarios on bed material sediment flux in a large river over decadal timescales: Water Resources Research, v. 42, no. 12, Article W12415; 14 p., https://doi.org/10.1029/2006WR004894.","productDescription":"Article W12415; 14 p.","costCenters":[],"links":[{"id":477355,"rank":1,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1029/2006wr004894","text":"Publisher Index Page"},{"id":236641,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"42","issue":"12","noUsgsAuthors":false,"publicationDate":"2006-12-21","publicationStatus":"PW","scienceBaseUri":"505a5c48e4b0c8380cd6fb7d","contributors":{"authors":[{"text":"Singer, Michael B.","contributorId":168369,"corporation":false,"usgs":false,"family":"Singer","given":"Michael","email":"","middleInitial":"B.","affiliations":[{"id":25268,"text":"University of St Andrews, UK","active":true,"usgs":false}],"preferred":false,"id":419223,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Dunne, Thomas","contributorId":146518,"corporation":false,"usgs":false,"family":"Dunne","given":"Thomas","email":"","affiliations":[{"id":6710,"text":"University of California, Santa Barbara, CA","active":true,"usgs":false}],"preferred":false,"id":419222,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

The fast loess accumulation during the late Wisconsin glaciation interacted with the incipient pedogenesis and caused unclear boundaries of loess-paleosol alternations in soil horizonation and mineralogy. Parameters of grain size distribution, sedimentation rate, matrix carbonate content and diffuse reflectance (i.e. soil colors and iron oxides) are used in this paper to discuss the geological and pedological influences for the Peoria Loess in Keller Farm section in southern Illinois. The multi-proxy analysis revealed that many paleosol A horizons, defined by the diffuse reflectance variability, contain finer-grained materials with a relatively higher sedimentation rate. It suggests that glaciofluvial sediments were available in the source areas for uploading eolian dust during the temporary ice sheet retreats. The denser vegetation and wetter surface soils on the loess deposit area could increase the dust trapping efficiency and caused a greater accumulation rate of loess deposits. The coarser-grained materials and slower sedimentation rate are often found in loess layers. It suggests that strong surface winds transported the coarser-grained materials from local dust sources and sparse vegetation and dry surface soils reduced the dust trapping efficiency during the ice sheet readvance. The strong interactions between the geological and pedological processes played an important role on the loess-paleosol alternations in southern Illinois during the late Wisconsin glaciation. ?? 2006 Elsevier B.V.
