Over the long-term(1920–1992), the simulations yielded a time history of terrestrial uptake that is consistent (within the uncertainty) with a long-term analysis based on ice core and atmospheric CO<sub>2</sub> data. Up to 1958, three of four analyses indicated a net release of carbon from terrestrial ecosystems to the atmosphere caused by cropland establishment. After 1958, all analyses indicate a net uptake of carbon by terrestrial ecosystems, primarily because of the physiological effects of rapidly rising atmospheric CO<sub>2</sub>. During the 1980s the simulations indicate that terrestrial ecosystems stored between 0.3 and 1.5 Pg C yr−1, which is within the uncertainty of analysis based on CO<sub>2</sub> and O<sub>2</sub> budgets. Three of the four models indicated (in accordance with O<sub>2</sub> evidence) that the tropics were approximately neutral while a net sink existed in ecosystems north of the tropics. Although all of the models agree that the long-term effect of climate on carbon storage has been small relative to the effects of increasing atmospheric CO<sub>2</sub> and land use, the models disagree as to whether climate variability and change in the twentieth century has promoted carbon storage or release. Simulated interannual variability from 1958 generally reproduced the El Niño/Southern Oscillation (ENSO)-scale variability in the atmospheric CO<sub>2</sub> increase, but there were substantial differences in the magnitude of interannual variability simulated by the models. The analysis of the ability of the models to simulate the changing amplitude of the seasonal cycle of atmospheric CO<sub>2</sub> suggested that the observed trend may be a consequence of CO<sub>2</sub> effects, climate variability, land use changes, or a combination of these effects. The next steps for improving the process-based simulation of historical terrestrial carbon include (1) the transfer of insight gained from stand-level process studies to improve the sensitivity of simulated carbon storage responses to changes in CO<sub>2</sub> and climate, (2) improvements in the data sets used to drive the models so that they incorporate the timing, extent, and types of major disturbances, (3) the enhancement of the models so that they consider major crop types and management schemes, (4) development of data sets that identify the spatial extent of major crop types and management schemes through time, and (5) the consideration of the effects of anthropogenic nitrogen deposition. The evaluation of the performance of the models in the context of a more complete consideration of the factors influencing historical terrestrial carbon dynamics is important for reducing uncertainties in representing the role of terrestrial ecosystems in future projections of the Earth system.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Global Biogeochemical Cycles","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Wiley","doi":"10.1029/2000GB001298","usgsCitation":"McGuire, A., Sitch, S., Clein, J.S., Dargaville, R., Esser, G., Foley, J., Heimann, M., Joos, F., Kaplan, J., Kicklighter, D., Meier, R., Melillo, J.M., Moore, B., Prentice, I.C., Ramankutty, N., Reichenau, T., Schloss, A., Tian, H., Williams, L., and Wittenberg, U., 2001, Carbon balance of the terrestrial biosphere in the twentieth century: analyses of CO<sub>2</sub>, climate and land use effects with four process-based ecosystem models: Global Biogeochemical Cycles, v. 15, no. 1, p. 183-206, https://doi.org/10.1029/2000GB001298.","productDescription":"24 p.","startPage":"183","endPage":"206","numberOfPages":"24","costCenters":[{"id":108,"text":"Alaska Cooperative Fish and Wildlife Research Unit","active":false,"usgs":true}],"links":[{"id":478829,"rank":0,"type":{"id":41,"text":"Open Access External Repository Page"},"url":"https://boris.unibe.ch/158812/","text":"External Repository"},{"id":281545,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":281544,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1029/2000GB001298"}],"volume":"15","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"53cd502be4b0b290850f32c1","contributors":{"authors":[{"text":"McGuire, A.

Core 94-PC27 sampled nonmarine siltstone similar in facies and age to uppermost Triassic to lower Lower Jurassic and mid– Lower Cretaceous beds in the 4 to > 5 km Mesozoic section on Franz Josef Land, on the outer Barents shelf. A ca. 250 Ma peak in the cumulative frequency curve of detrital zircons from the siltstone, dated by U- Th-Pb analysis, suggests a source in the post-tectonic syenites of northern Taymyr and nearby islands in the Kara Sea. Textural trends reported in the literature indicate that the Lower Jurassic nonmarine strata of Franz Josef Land coarsen to the southeast; this suggests the existence of a sedimentary system in which detrital zircons could be transported from the northern Taymyr Peninsula to the outer Barents shelf near the position of core 94-PC27 prior to opening of the Eurasia Basin. Correlation of the coaly siltstone in core 94-PC27 with part of the Mesozoic section on Franz Josef Land is compatible with the strong evidence from seafloor magnetic anomalies and bathymetry that Lomonosov Ridge is a continental fragment rifted from the Barents shelf during the Cenozoic. It also suggests that Lomonosov Ridge near the North Pole is underlain by a substantial section of unmetamorphosed Mesozoic marine and nonmarine sedimentary strata.\n\nCore 94-PC29 sampled cyclical deposits containing ice-rafted debris (IRD) overlying weakly consolidated laminated olive-black anoxic Neogene siltstone and mudstone with an average total organic carbon (TOC) of 4.1 wt%. The high TOC content of the mudstone indicates that during the Neogene, prior to the introduction of IRD into the Arctic seas about 3.3 Ma (early late Pliocene), the shallow waters of the central Arctic Ocean supported significant primary photosynthetic organic production near the North Pole. These deposits also contain fine grains of siltstone that resemble the breccia-clast siltstone of core 94-PC27 and reworked Carboniferous, Cretaceous, and Tertiary palynomorphs that may have also originated in the bedrock of Lomonosov Ridge.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"GSA Bulletin","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Geological Society of America","doi":"10.1130/0016-7606(2001)113<1272:BCFNIF>2.0.CO;2","usgsCitation":"Grantz, A., Pease, V.L., Willard, D.A., Phillips, R., and Clark, D.L., 2001, Bedrock cores from 89° North: Implications for the geologic framework and Neogene paleoceanography of Lomonosov Ridge and a tie to the Barents shelf: GSA Bulletin, v. 113, no. 10, p. 1272-1281, https://doi.org/10.1130/0016-7606(2001)113<1272:BCFNIF>2.0.CO;2.","productDescription":"10 p.","startPage":"1272","endPage":"1281","numberOfPages":"10","costCenters":[],"links":[{"id":282867,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":282866,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1130/0016-7606(2001)113<1272:BCFNIF>2.0.CO;2"}],"otherGeospatial":"Lomonosov Ridge","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ 96.9,80.4 ], [ 96.9,84.9 ], [ 148.5,84.9 ], [ 148.5,80.4 ], [ 96.9,80.4 ] ] ] } } ] }","volume":"113","issue":"10","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"53cd4f05e4b0b290850f2749","contributors":{"authors":[{"text":"Grantz, Arthur agrantz@usgs.gov","contributorId":2585,"corporation":false,"usgs":true,"family":"Grantz","given":"Arthur","email":"agrantz@usgs.gov","affiliations":[{"id":312,"text":"Geology, Minerals, Energy, and Geophysics Science Center","active":true,"usgs":true}],"preferred":true,"id":491070,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Pease, Victoria L.","contributorId":101985,"corporation":false,"usgs":true,"family":"Pease","given":"Victoria","email":"","middleInitial":"L.","affiliations":[],"preferred":false,"id":491073,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Willard, Debra A. 0000-0003-4878-0942 dwillard@usgs.gov","orcid":"https://orcid.org/0000-0003-4878-0942","contributorId":2076,"corporation":false,"usgs":true,"family":"Willard","given":"Debra","email":"dwillard@usgs.gov","middleInitial":"A.","affiliations":[{"id":24693,"text":"Climate Research and Development","active":true,"usgs":true},{"id":411,"text":"National Climate Change and Wildlife Science Center","active":true,"usgs":true}],"preferred":true,"id":491069,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Phillips, R.

For pure strike-slip faults, the elastic rebound function derived from SAR interferometry is directly invertible from the distribution of elastic strain on the fault at criticality, just before the critical shear stress was exceeded and the fault ruptured. The Kocaeli earthquake, which was accompanied by as much as ∼5 m of surface displacement, distributed strain ∼110 km around the fault prior to faulting, although most of it was concentrated in a narrower and asymmetric 10-km-wide zone on either side of the fault. The use of SAR interferometry to document the distribution of elastic strain at the critical condition for faulting is clearly a valuable tool, both for scientific investigation and for the effective management of earthquake hazard.","language":"English","publisher":"Geological Society of America","doi":"10.1130/0091-7613(2001)029<0495:ERFTKE>2.0.CO;2","usgsCitation":"Mayer, L., and Lu, Z., 2001, Elastic rebound following the Kocaeli earthquake, Turkey, recorded using synthetic aperture radar interferometry: Geology, v. 29, no. 6, p. 495-498, https://doi.org/10.1130/0091-7613(2001)029<0495:ERFTKE>2.0.CO;2.","productDescription":"4 p.","startPage":"495","endPage":"498","numberOfPages":"4","costCenters":[{"id":222,"text":"Earth Resources Observation and Science (EROS) Center","active":true,"usgs":true}],"links":[{"id":281520,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"Turkey","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ 25.66,35.81 ], [ 25.66,42.11 ], [ 44.82,42.11 ], [ 44.82,35.81 ], [ 25.66,35.81 ] ] ] } } ] }","volume":"29","issue":"6","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"53cd5743e4b0b290850f7606","contributors":{"authors":[{"text":"Mayer, Larry","contributorId":77936,"corporation":false,"usgs":true,"family":"Mayer","given":"Larry","affiliations":[],"preferred":false,"id":489271,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Lu, Zhong 0000-0001-9181-1818 lu@usgs.gov","orcid":"https://orcid.org/0000-0001-9181-1818","contributorId":901,"corporation":false,"usgs":true,"family":"Lu","given":"Zhong","email":"lu@usgs.gov","affiliations":[],"preferred":true,"id":489270,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

The Landsat 7 mission, successfully launched on April 15, 1999, continues those observations and demonstrates significant progress in precise numerical radiometry, spectral differentiation, and seasonally repetitive monitoring. Substantial improvements in calibration procedures, both prior to launch and during normal operations, have also been made to ensure long-term stability in the acquired spectral radiometry. Landsat 7 data acquisitions are being driven by a long-term data acquisition plan that was designed to ensure that substantially cloud-free, seasonal coverage would be recorded and archived in the US for all land areas of the globe. NASA competitively selected a Landsat Science Team, consisting of representatives from US universities and government agencies, to exploit the Landsat 7 record for global change research. This team is addressing the technical and analytical means to process and analyze the core of this observation record, and for the first time in the history of the Landsat mission, the technical and operational aspects of the mission are being driven by the goals of the US science community. The expected outcome of these efforts is a rapid improvement in understanding the Earth system, as well as conceptual knowledge that will underpin significant advancements in the application of this technology for commercial, operational, educational, and research purposes. Pathways to achieve effective Landsat continuity in the early decades of the 21st century are also being given careful attention, and there is no question that the lessons learned from the Landsat 7 mission will strongly influence these next-generation sensor systems.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Remote Sensing of Environment","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Elsevier","doi":"10.1016/S0034-4257(01)00262-0","usgsCitation":"Goward, S.N., Masek, J.G., Williams, D.L., Irons, J.R., and Thompson, R., 2001, The Landsat 7 mission: terrestrial research and applications for the 21st century: Remote Sensing of Environment, v. 78, no. 1-2, p. 3-12, https://doi.org/10.1016/S0034-4257(01)00262-0.","productDescription":"10 p.","startPage":"3","endPage":"12","numberOfPages":"10","costCenters":[{"id":222,"text":"Earth Resources Observation and Science (EROS) Center","active":true,"usgs":true}],"links":[{"id":282862,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":282861,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/S0034-4257(01)00262-0"}],"volume":"78","issue":"1-2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"53cd76fee4b0b2908510b454","contributors":{"authors":[{"text":"Goward, Samuel N.","contributorId":44459,"corporation":false,"usgs":true,"family":"Goward","given":"Samuel","email":"","middleInitial":"N.","affiliations":[],"preferred":false,"id":491065,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Masek, Jeffrey G.","contributorId":58188,"corporation":false,"usgs":true,"family":"Masek","given":"Jeffrey","email":"","middleInitial":"G.","affiliations":[],"preferred":false,"id":491066,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Williams, Darrel L.","contributorId":20627,"corporation":false,"usgs":true,"family":"Williams","given":"Darrel","email":"","middleInitial":"L.","affiliations":[],"preferred":false,"id":491064,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Irons, James R.","contributorId":59284,"corporation":false,"usgs":false,"family":"Irons","given":"James","email":"","middleInitial":"R.","affiliations":[{"id":7049,"text":"NASA Goddard Space Flight Center","active":true,"usgs":false}],"preferred":false,"id":491067,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Thompson, R.J.","contributorId":93624,"corporation":false,"usgs":true,"family":"Thompson","given":"R.J.","email":"","affiliations":[],"preferred":false,"id":491068,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}}

Borehole recordings provide a wide frequency bandwidth, typically 1 to 200–300 Hz, and greatly reduce seismic noise and path effects compared to surface recordings. We calculated source parameters in both the time and frequency domains for P and S waves. At frequencies above the corner frequency, spectra decay faster than ω<sup>3</sup>, indicating that attenuation plays an important role in shaping the spectra (path averaged Q<sub>p</sub> = 100–400, Q<sub>s</sub> = 200–800). Source parameters are corrected for attenuation and radiation pattern.\n\nBoth static stress drops and apparent stresses range from approximately 0.01 to 30 MPa. Although static stress drops do not vary with seismic moment for these data, our analyses are consistent with apparent stress increasing with increasing moment. To estimate tectonic driving stress and seismic efficiencies in the region, we combined source parameter measurements with knowledge of the stress field and a Coulomb failure criterion to infer a driving stress of 40–70 MPa.

Our main goal is to identify and discuss common features and peculiarities in the temporal evolution of earthquake sequences that may reflect similarities and differences in the generating processes between these volcanic systems. In particular, we tried to characterize the time series of the number of events and of the seismic energy release in terms of stochastic, deterministic, and chaotic components. The time sequences from each area consist of thousands of earthquakes that allow a detailed quantitative analysis and comparison. The results obtained showed no evidence for either deterministic or chaotic components in the earthquake sequences in Long Valley caldera, which appears to be dominated by stochastic behavior. In contrast, earthquake sequences at Phlegrean Fields and Mount Vesuvius show a deterministic signal mainly consisting of a 24-hour periodicity. Our analysis suggests that the modulation in seismicity is in some way related to thermal diurnal processes, rather than luni-solar tidal effects. Independently from the process that generates these periodicities on the seismicity., it is suggested that the lack (or presence) of diurnal cycles is seismic swarms of volcanic areas could be closely linked to the presence (or lack) of magma motion.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Bulletin of the Seismological Society of America","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Seismological Society of America","doi":"10.1785/0120000045","usgsCitation":"Marzocchi, W., Vilardo, G., Hill, D., Ricciardi, G., and Ricco, C., 2001, Common features and peculiarities of the seismic activity at Phlegraean Fields, Long Valley, and Vesuvius: Bulletin of the Seismological Society of America, v. 91, no. 2, p. 191-205, https://doi.org/10.1785/0120000045.","productDescription":"15 p.","startPage":"191","endPage":"205","numberOfPages":"15","costCenters":[],"links":[{"id":281518,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":281514,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1785/0120000045"}],"country":"Italy;United States","state":"California","city":"Long Valley;Phlegraean Fields;Vesuvius","volume":"91","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"53cd51e4e4b0b290850f430f","contributors":{"authors":[{"text":"Marzocchi, W.","contributorId":29156,"corporation":false,"usgs":true,"family":"Marzocchi","given":"W.","affiliations":[],"preferred":false,"id":489267,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Vilardo, G.","contributorId":94969,"corporation":false,"usgs":true,"family":"Vilardo","given":"G.","email":"","affiliations":[],"preferred":false,"id":489269,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Hill, D.P.","contributorId":27432,"corporation":false,"usgs":true,"family":"Hill","given":"D.P.","email":"","affiliations":[],"preferred":false,"id":489266,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Ricciardi, G.P.","contributorId":50817,"corporation":false,"usgs":true,"family":"Ricciardi","given":"G.P.","email":"","affiliations":[],"preferred":false,"id":489268,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Ricco, C.","contributorId":24683,"corporation":false,"usgs":true,"family":"Ricco","given":"C.","affiliations":[],"preferred":false,"id":489265,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}}

Data on Lake Bonneville basin sand and gravel deposit thickness, volume, grain size, percent of fines, and durability were statistically analyzed to detect variations associated with geologic domains, geographic location, Lake Bonneville shorelines, and sand and gravel deposit type, and to construct quantitative deposit models. Analysis showed several trends; (1) sand and gravel in younger shorelines was slightly more durable and the deposits considerably larger in volume, (2) younger shorelines are also more likely to contain more than one genetic deposit type, (3) the volume of terrace deposits is larger than beach deposits, (4) terraces and beaches are generally thicker than spits and bars, (5) the northern part of the Bonneville Basin contains slightly more durable sand and gravel than the southern part of the basin and is more likely to contain deposits composed of more than one genetic deposit type, and (6) the Wasatch domain deposits are composed of more than one genetic deposit type more often than deposits of the Basin and Range domain. Three additional conclusions with immediate economic significance are; (1) the median sand and gravel deposit in the Wasatch domain, 360,000 m<sup>3</sup> (275,000 yd<sup>3</sup>), is three times larger than that of the Basin and Range domain (120,000 m<sup>3</sup> [90,000 yd<sup>3</sup>]), (2) the median deposit thickness in the Wasatch domain, 5.8 m (19.0 ft), is nearly twice that of the Basin and Range domain (3 m [10 ft]), and (3) the Wasatch domain also contains slightly larger diameter gravel. These three conclusions are significant because the trend for sand and gravel development in the Bonneville Basin is to move from the Wasatch domain to the Basin and Range domain. Smaller, thinner deposits with smaller diameter gravel will require more surface area to mine than would have been necessary in the Wasatch domain. The result is a higher cost for sand and gravel in construction projects in the Salt Lake City area, especially since the gravel must also be hauled further.","largerWorkTitle":"Proceedings of the 35th Forum on the Geology of Industrial Minerals: the Intermountain West Forum 1999","conferenceTitle":"35th Forum on the Geology of Industrial Minerals: the Intermountain West Forum 1999","conferenceDate":"1999-05-02T00:00:00","conferenceLocation":"Salt Lake City, UT","language":"English","publisher":"Utah Geological Survey","isbn":"1-55791-654-3","usgsCitation":"Bliss, J.D., and Bolm, K.S., 2001, Statistical analysis of sand and gravel aggregate deposits of late Pleistocene Lake Bonneville, Utah, p. 195-214.","productDescription":"p. 195-214","numberOfPages":"20","costCenters":[],"links":[{"id":281917,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Idaho;Nevada;Utah","otherGeospatial":"Lake Bonneville","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -115.5691,36.9979 ], [ -115.5691,43.1183 ], [ -109.0411,43.1183 ], [ -109.0411,36.9979 ], [ -115.5691,36.9979 ] ] ] } } ] }","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"53cd73fce4b0b2908510942f","contributors":{"authors":[{"text":"Bliss, James D. jbliss@usgs.gov","contributorId":2790,"corporation":false,"usgs":true,"family":"Bliss","given":"James","email":"jbliss@usgs.gov","middleInitial":"D.","affiliations":[{"id":312,"text":"Geology, Minerals, Energy, and Geophysics Science Center","active":true,"usgs":true}],"preferred":true,"id":489845,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Bolm, K.

The sediment generation (275 ± 65 g m<sup>−2</sup> yr<sup>−1</sup>) and bedrock equivalent lowering rates (102 ± 24 m myr<sup>−1</sup>) we determine are sufficient to support at least three arroyo cycles in the past 3,000 years, consistent with rates calculated from a physical sediment budget within the basin and regional rates determined using other techniques. Nuclide concentrations measured in different sediment sources and reservoirs suggest that the arroyo is a good spatial and temporal integrator of sediment and associated nuclide concentrations from throughout the basin, that the basin is in steady-state, and that nuclide concentration is independent of sediment grain size. Differences between nuclide concentrations measured in sediment sources and reservoirs reflect sediment residence times and indicate that subcolluvial bedrock weathering on hillslopes supplies more sediment to the basin than erosion of exposed bedrock.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Quaternary Research","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Elsevier","doi":"10.1006/qres.2000.2211","usgsCitation":"Clapp, E.M., Bierman, P.R., Nichols, K.K., Pavich, M., and Caffee, M.A., 2001, Rates of sediment supply to arroyos from upland erosion determined using <i>in situ</i> produced cosmogenic <sup>10</sup>Be and <sup>26</sup>Al: Quaternary Research, v. 55, no. 2, p. 235-245, https://doi.org/10.1006/qres.2000.2211.","productDescription":"11 p.","startPage":"235","endPage":"245","numberOfPages":"11","costCenters":[],"links":[{"id":282700,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":282699,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1006/qres.2000.2211"}],"country":"United States","state":"New Mexico","otherGeospatial":"Arroyo Chavez Sub-basin","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -107.114444,35.708333 ], [ -107.114444,35.75 ], [ -107.0,35.75 ], [ -107.0,35.708333 ], [ -107.114444,35.708333 ] ] ] } } ] }","volume":"55","issue":"2","noUsgsAuthors":false,"publicationDate":"2017-01-20","publicationStatus":"PW","scienceBaseUri":"53cd6f34e4b0b29085106465","contributors":{"authors":[{"text":"Clapp, Erik M.","contributorId":40892,"corporation":false,"usgs":true,"family":"Clapp","given":"Erik","email":"","middleInitial":"M.","affiliations":[],"preferred":false,"id":490872,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Bierman, Paul R. 0000-0001-9627-4601","orcid":"https://orcid.org/0000-0001-9627-4601","contributorId":19041,"corporation":false,"usgs":true,"family":"Bierman","given":"Paul","email":"","middleInitial":"R.","affiliations":[],"preferred":false,"id":490869,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Nichols, Kyle K.","contributorId":73917,"corporation":false,"usgs":true,"family":"Nichols","given":"Kyle","email":"","middleInitial":"K.","affiliations":[],"preferred":false,"id":490873,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Pavich, Milan","contributorId":32241,"corporation":false,"usgs":true,"family":"Pavich","given":"Milan","affiliations":[],"preferred":false,"id":490870,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Caffee, Marc A.","contributorId":36048,"corporation":false,"usgs":false,"family":"Caffee","given":"Marc","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":490871,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}}

Low rainfall (approximately 170 mm/yr) and a thick unsaturated zone (500–1000 m) are important physical attributes of the site because the quantity of water likely to reach the waste and the paths and rates of movement of the water to the saturated zone under future climates would be major factors in controlling the concentrations and times of arrival of radionuclides at the surrounding accessible environment. The framework for understanding the hydrologic processes that occur at this site and that control how quickly water will penetrate through the unsaturated zone to the water table has evolved during the past 15 yr. Early conceptual models assumed that very small volumes of water infiltrated into the bedrock (0.5–4.5 mm/yr, or 2–3 percent of rainfall), that much of the infiltrated water flowed laterally within the upper nonwelded units because of capillary barrier effects, and that the remaining water flowed down faults with a small amount flowing through the matrix of the lower welded, fractured rocks. It was believed that the matrix had to be saturated for fractures to flow. However, accumulating evidence indicated that infiltration rates were higher than initially estimated, such as infiltration modeling based on neutron borehole data, bomb-pulse isotopes deep in the mountain, perched water analyses and thermal analyses. Mechanisms supporting lateral diversion did not apply at these higher fluxes, and the flux calculated in the lower welded unit exceeded the conductivity of the matrix, implying vertical flow of water in the high permeability fractures of the potential repository host rock, and disequilibrium between matrix and fracture water potentials. The development of numerical modeling methods and parameter values evolved concurrently with the conceptual model in order to account for the observed field data, particularly fracture flow deep in the unsaturated zone. This paper presents the history of the evolution of conceptual models of hydrology and numerical models of unsaturated zone flow at Yucca Mountain, Nevada (Flint, A.L., Flint, L.E., Kwicklis, E.M., Bodvarsson, G.S., Fabryka-Martin, J.M., 2001. Hydrology of Yucca Mountain. Reviews of Geophysics in press). This retrospective is the basis for recommendations for optimizing the efficiency with which a viable and robust conceptual model can be developed for a complex site.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Hydrology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Elsevier","doi":"10.1016/S0022-1694(01)00358-4","usgsCitation":"Flint, A.L., Flint, L.E., Bodvarsson, G.S., Kwicklis, E.M., and Fabryka-Martin, J., 2001, Evolution of the conceptual model of unsaturated zone hydrology at Yucca Mountain, Nevada: Journal of Hydrology, v. 247, no. 1-2, p. 1-30, https://doi.org/10.1016/S0022-1694(01)00358-4.","productDescription":"30 p.","startPage":"1","endPage":"30","numberOfPages":"30","costCenters":[{"id":154,"text":"California Water Science Center","active":true,"usgs":true}],"links":[{"id":281253,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":281252,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/S0022-1694(01)00358-4"}],"country":"United States","state":"Nevada","otherGeospatial":"Yucca Mountain","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -117.2379,35.4976 ], [ -117.2379,37.501 ], [ -115.4938,37.501 ], [ -115.4938,35.4976 ], [ -117.2379,35.4976 ] ] ] } } ] }","volume":"247","issue":"1-2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"53cd58abe4b0b290850f83e4","contributors":{"authors":[{"text":"Flint, Alan L. 0000-0002-5118-751X aflint@usgs.gov","orcid":"https://orcid.org/0000-0002-5118-751X","contributorId":1492,"corporation":false,"usgs":true,"family":"Flint","given":"Alan","email":"aflint@usgs.gov","middleInitial":"L.","affiliations":[{"id":154,"text":"California Water Science Center","active":true,"usgs":true},{"id":657,"text":"Western Geographic Science Center","active":true,"usgs":true}],"preferred":true,"id":488897,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Flint, Lorraine E. 0000-0002-7868-441X lflint@usgs.gov","orcid":"https://orcid.org/0000-0002-7868-441X","contributorId":1184,"corporation":false,"usgs":true,"family":"Flint","given":"Lorraine","email":"lflint@usgs.gov","middleInitial":"E.","affiliations":[{"id":154,"text":"California Water Science Center","active":true,"usgs":true}],"preferred":true,"id":488896,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Bodvarsson, Gudmundur S.","contributorId":36851,"corporation":false,"usgs":true,"family":"Bodvarsson","given":"Gudmundur","email":"","middleInitial":"S.","affiliations":[],"preferred":false,"id":488900,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Kwicklis, Edward M.","contributorId":25970,"corporation":false,"usgs":true,"family":"Kwicklis","given":"Edward","email":"","middleInitial":"M.","affiliations":[],"preferred":false,"id":488899,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Fabryka-Martin, June","contributorId":6760,"corporation":false,"usgs":true,"family":"Fabryka-Martin","given":"June","email":"","affiliations":[],"preferred":false,"id":488898,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}}

Although these sands have been penetrated by numerous exploration and development wells, uncertainty remains as to their extent, distribution, and ultimate effect on reservoir performance. The section is geologically complex (thin beds, injected sands, shale clasts and laminae, and faulting), and also contains a field-wide primary gas cap. With a depletion plan involving both gas and water injection, geologic/reservoir characterization of the Eocene is critical for prudent resource management during depletion. With this goal, resistivity modeling and core-based thin bed reservoir description from the first phase of development drilling have been integrated with seismic attribute mapping. Detailed core description, core permeability and grain size distribution data delineate six facies and help in distinguishing laterally continuous massive and laminated sands from potentially non-connected injection sands and non-reservoir quality siltstones and tuffs. Volumetric assessment of the thin sand resource has been enhanced by I-D forward modeling of induction log response using a commercial resistivity modeling program, R,BAN. After defining beds and facies with core and high resolution log data, the AHF60 array induction curve response was approximated using the 6FF40 response. Because many of the beds were thinner than 6FF40 resolution, the modeling is considered to provide a lower bound on R,. However, for most beds this model-based R, is significantly higher than that provided by one-foot vertical resolution shallow resistivity data, and is thought to be the best available estimate of true formation resistivity. Sensitivities in STOOIP were assessed with multiple R, earth models which can later be tested against production results. In addition, water saturation height functions, developed in vertical wells and thick beds, can be validated in deviated wells with thin beds. Sand thickness models constrained by this logand core-based petrophysical analysis were used to build impedance seismic synthetic sections from which seismic attributes could be extracted and calibrated. The model-based attribute calibration was then applied to the seismic impedance 3-D cube permitting sand thickness to be mapped and reservoir geology to be modeled with significantly more detail than previously possible. These results will guide the field''s reservoir management and assist in the delineation of new targets.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Petrophysics","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Society of Petrophysicists and Well-Log Analysts","usgsCitation":"Paillet, F.L., Haynes, F., and Buretz, O., 2001, Applications of resistivity modeling in reservoir development: examples from Balder Field, Norwegian North Sea: Petrophysics, v. 42, no. 1, p. 17-18.","productDescription":"2 p.","startPage":"17","endPage":"18","numberOfPages":"2","costCenters":[],"links":[{"id":281585,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"otherGeospatial":"Norwegian Sea;Balder Field","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -13.5,69.95 ], [ -13.5,76.56 ], [ 25.59,76.56 ], [ 25.59,69.95 ], [ -13.5,69.95 ] ] ] } } ] }","volume":"42","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"53cd4dace4b0b290850f1a00","contributors":{"authors":[{"text":"Paillet, Frederick L.","contributorId":63820,"corporation":false,"usgs":true,"family":"Paillet","given":"Frederick","email":"","middleInitial":"L.","affiliations":[],"preferred":false,"id":489410,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Haynes, F.M.","contributorId":19077,"corporation":false,"usgs":true,"family":"Haynes","given":"F.M.","email":"","affiliations":[],"preferred":false,"id":489408,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Buretz, O.M.","contributorId":41739,"corporation":false,"usgs":true,"family":"Buretz","given":"O.M.","email":"","affiliations":[],"preferred":false,"id":489409,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

Accurate event location can improve the probability of determining whether or not a small event, recorded predominantly by local and regional stations, is a nuclear explosion. For those portions of the earth where crustal velocities are not well established, reference event calibration techniques offer a method of increased locational accuracy and reduced locational bias.\nIn this study, data from a set of mining events with good ground-truth data in the Powder River Basin region of eastern Wyoming are used to investigate the potential of event calibration techniques in the area. Results of this study are compared with locations published in the prototype International Data Center’s Reviewed Event Bulletin (REB). A Joint Hypocenter Determination (JHD) method was applied to a set of 23 events. Four of those events with superior ground-truth control (mining company report or Global Positioning System data) were used as JHD reference events, Nineteen (83%) of the solutions converged and the resulting set of station-phase travel-time corrections from the JHD results was then tested. When those travel-time corrections were applied individually to the four events with good ground-truth control, the average locational error reduced the original REB location error from 16.1 km to 5.7 km (65% improvement). The JHD locations indicated reduced locational bias and all of the individual error ellipses enclosed the actual known event locations.\nGiven a set of well-recorded calibration events, it appears that the JHD methodology is a viable technique for improving locational accuracy of future small events where the location depends on arrival times from predominantly local and/or regional stations. In this specific case, the International Association of Seismology and the Physics of the Earth’s Interior (IASPEI) travel-time tables, coupled with JHDderived travel-time corrections, may obviate the need for an accurately known regional velocity structure in the Powder River Basin region.","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"Monitoring the comprehensive Nuclear-Test-Ban Treaty: Sourse location","largerWorkSubtype":{"id":15,"text":"Monograph"},"language":"English","publisher":"Springer","doi":"10.1007/978-3-0348-8250-7_8","isbn":"978-3-0348-8250-7","usgsCitation":"Finn, C., Kraft, G.D., Sibol, M.S., Jones, R.L., and Pulaski, M.E., 2001, Relocation of Wyoming mine production blasts using calibration explosions, chap. <i>of</i> Monitoring the comprehensive Nuclear-Test-Ban Treaty: Sourse location, v. 158, no. 1-2, p. 105-116, https://doi.org/10.1007/978-3-0348-8250-7_8.","productDescription":"12 p.","startPage":"105","endPage":"116","costCenters":[{"id":300,"text":"Geologic Hazards Science Center","active":true,"usgs":true},{"id":422,"text":"National Geomagnetism Program","active":false,"usgs":true}],"links":[{"id":281251,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Montana, Wyoming","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -104.0076,42.6259 ], [ -104.0076,46.7850 ], [ -108.1714,46.7850 ], [ -108.1714,42.6259 ], [ -104.0076,42.6259 ] ] ] } } ] }","volume":"158","issue":"1-2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"53cd7043e4b0b29085106ef5","contributors":{"authors":[{"text":"Finn, Carol A. 0000-0003-3144-1645 cafinn@usgs.gov","orcid":"https://orcid.org/0000-0003-3144-1645","contributorId":152589,"corporation":false,"usgs":true,"family":"Finn","given":"Carol A.","email":"cafinn@usgs.gov","affiliations":[{"id":300,"text":"Geologic Hazards Science Center","active":true,"usgs":true}],"preferred":false,"id":488891,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Kraft, Gordon D.","contributorId":101186,"corporation":false,"usgs":true,"family":"Kraft","given":"Gordon","email":"","middleInitial":"D.","affiliations":[],"preferred":false,"id":488895,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Sibol, Matthew S.","contributorId":92578,"corporation":false,"usgs":true,"family":"Sibol","given":"Matthew","email":"","middleInitial":"S.","affiliations":[],"preferred":false,"id":488894,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Jones, Ronald L.","contributorId":49702,"corporation":false,"usgs":true,"family":"Jones","given":"Ronald","email":"","middleInitial":"L.","affiliations":[],"preferred":false,"id":488892,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Pulaski, Mark E.","contributorId":72299,"corporation":false,"usgs":true,"family":"Pulaski","given":"Mark","email":"","middleInitial":"E.","affiliations":[],"preferred":false,"id":488893,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}}
