The 23 year climatology (1979-2001) of the multidecadal dynamically downscaled simulations forced by the National Centers for Environmental Prediction-Department of Energy (NCEP-DOE) Reanalysis II at the lateral boundaries verify quite well with the observed climatology. The variations at diurnal and interannual time scales are also well simulated with respect to the observations. We show from composite analyses made from these downscaled simulations that sea breezes in northwestern Florida are associated with changes in the size of the Atlantic Warm Pool (AWP) on interannual time scales. In large AWP years when the North Atlantic Subtropical High becomes weaker and moves further eastward relative to the small AWP years, a large part of the southeast U.S. including Florida comes under the influence of relatively strong anomalous low-level northerly flow and large-scale subsidence consistent with the theory of the Sverdrup balance. This tends to suppress the diurnal convection over the Florida panhandle coast in large AWP years. This study is also an illustration of the benefit of dynamic downscaling in understanding the low-frequency variations of the sea breeze.

In North America IHNV has three major genogroups designated U, M, and L. Host-specificity of the M and U genogroups of IHNV has been established both in the field and in experimental challenges, with M isolates being more prevalent and more virulent in rainbow trout (Oncorhynchus mykiss), and U isolates being more prevalent and highly virulent in sockeye salmon (Oncorhynchus nerka). In this study, efficacy of DNA vaccines containing either M (pM) or U (pU) virus glycoprotein genes was investigated during intra- and cross-genogroup challenges in rainbow trout. In virus challenges at 7 days post-vaccination (early antiviral response), both pM and pU were highly protective against either M or U IHNV. In challenges at 28 days post-vaccination (specific antiviral response), both pM and pU were protective against M IHNV but the homologous pM vaccine was significantly more protective than pU in one of two experiments. At this stage both pM and pU induced comparably high protection against U IHNV challenge. Correlates of protection were also investigated by assessing the expression of the interferon-stimulated gene Mx-1 and the production of neutralizing antibodies (NAbs) following pM or pU DNA vaccination. Mx-1 gene expression, measured at 4 and 7 days post-vaccination as an indicator of the host innate immune response, was found to be significantly higher after pM than pU vaccination in some cases. Neutralizing antibody was produced in response to the two vaccines, but antibody titers did not show consistent correlation with protection. The results show that the rainbow trout innate and adaptive immune responses have some ability to distinguish between the U and M genogroup IHNV, but overall the pM and pU vaccines were protective against both homologous and cross-genogroup challenges.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Fish and Shellfish Immunology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1016/j.fsi.2011.03.003","issn":"10504648","usgsCitation":"Penaranda, M., LaPatra, S., and Kurath, G., 2011, Specificity of DNA vaccines against the U and M genogroups of infectious hematopoietic necrosis virus (IHNV) in rainbow trout (Oncorhynchus mykiss): Fish and Shellfish Immunology, v. 31, no. 1, p. 43-51, https://doi.org/10.1016/j.fsi.2011.03.003.","startPage":"43","endPage":"51","numberOfPages":"9","costCenters":[],"links":[{"id":218570,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.fsi.2011.03.003"},{"id":246593,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"31","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505b952ae4b08c986b31ad97","contributors":{"authors":[{"text":"Penaranda, M.M.D.","contributorId":17845,"corporation":false,"usgs":true,"family":"Penaranda","given":"M.M.D.","email":"","affiliations":[],"preferred":false,"id":454465,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"LaPatra, S.

This study simulated soil organic C (SOC) dynamics within 0–100&nbsp;cm depth of soils across the state of Iowa in the USA from 1972 to 2007 using the General Ensemble biogeochemical Modeling System (GEMS). The model outputs with variation coefficient were analyzed and assembled from simulation unit to the state scale based upon major land use types at annual step. Results from this study indicate that soils (within a depth of 0–100&nbsp;cm) in Iowa had been a SOC source at a rate of 190&nbsp;±&nbsp;380&nbsp;kg C&nbsp;ha</span><sup>−1</sup><span>&nbsp;yr</span><sup>−1</sup><span>. This was likely caused by the installation of a massive drainage system which led to the release of SOC from deep soil layers previously protected under poor drainage conditions. The annual crop rotation was another major force driving SOC variation and resulted in spatial variability of annual budgets in all croplands. Annual rate of change of SOC stocks in all land types depended significantly on the baseline SOC levels; soils with higher SOC levels tended to be C sources, and those with lower levels tended to be C sinks. Management practices (e.g., conservation tillage and residue management practices) slowed down the C emissions from Iowa soils, but could not reverse the general trend of net SOC loss in view of the entire state due mainly to a high level of baseline SOC stocks.</span></p>","language":"English","publisher":"Elsevier","doi":"10.1016/j.agee.2010.11.017","issn":"01678809","usgsCitation":"Liu, S., Tan, Z., Li, Z., Zhao, S., and Yuan, W., 2011, Are soils of Iowa USA currently a carbon sink or source?

We monitored cave-air compositions, in situ calcite growth, dripwater composition and drip rate every 4–6</span><span>&nbsp;</span><span>weeks. Three groups of drip sites are delineated (Groups 1–3) based on geochemical variations in dripwater composition. Quantitative modeling of mineral-solution reactions within the host carbonate rock and cave environments is used to identify mechanisms that can account for variations in dripwater compositions. The covariation of Mg/Ca (and Sr/Ca) and Sr isotopes is key in delineating whether Mg/Ca and Sr/Ca variations are dictated by water–rock interaction (i.e., calcite or dolomite recrystallization) or prior calcite precipitation (PCP). Group 1 dripwater compositions reflects a narrow range of the extent of water–rock interaction followed by varying amounts of prior calcite precipitation (PCP). Group 2 dripwater compositions are controlled by varying amounts of water–rock interaction with little to no PCP influence. Group 3 dripwater compositions are dictated by variable extents of both water–rock interaction and PCP. Group 1 drip sites show seasonal variations in dripwater Mg/Ca and Sr/Ca, whereas the other drip sites do not. In contrast to the findings of most previous dripwater Mg/Ca–Sr/Ca studies, these seasonal variations (at Group 1 drip sites) are independent of changes in water flux (i.e., rainfall and/or drip rate), and instead significantly correlate with changes in cave-air CO</span><sub>2</sub><span>&nbsp;concentrations. These results are consistent with lower cave-air CO</span><sub>2</sub><span>, related to cool season ventilation of the cave atmosphere, enhancing calcite precipitation and leading to dripwater geochemical evolution via PCP. Group 1 dripwater Mg/Ca and Sr/Ca seasonality and evidence for PCP as a mechanism that can account for that seasonality, have two implications for many other regions where seasonal ventilation of caves is likely: (1) speleothem trace-element records may provide seasonal signals, and (2) such records may be biased toward recording climate conditions during the season when calcite is depositing. Additionally, we use our results to construct a forward model that illustrates the types of speleothem Mg/Ca and Sr/Ca variations that would result from varying controls on dripwater compositions. The model provides a basis for interpreting paleo-dripwater controls from high frequency Mg/Ca and Sr/Ca variations for speleothems from caves at which long term monitoring studies are not feasible.</span></p>","language":"English","publisher":"Elsevier","doi":"10.1016/j.gca.2011.03.025","issn":"00167037","usgsCitation":"Wong, C., Banner, J., and Musgrove, M., 2011, Seasonal dripwater Mg/Ca and Sr/Ca variations driven by cave ventilation: Implications for and modeling of speleothem paleoclimate records: Geochimica et Cosmochimica Acta, v. 75, no. 12, p. 3514-3529, https://doi.org/10.1016/j.gca.2011.03.025.","productDescription":"16 p.","startPage":"3514","endPage":"3529","costCenters":[{"id":583,"text":"Texas Water Science Center","active":true,"usgs":true}],"links":[{"id":246309,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":218310,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.gca.2011.03.025"}],"volume":"75","issue":"12","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505b889ae4b08c986b316a60","contributors":{"authors":[{"text":"Wong, C.I.","contributorId":98574,"corporation":false,"usgs":true,"family":"Wong","given":"C.I.","email":"","affiliations":[],"preferred":false,"id":455270,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Banner, J.L.","contributorId":95683,"corporation":false,"usgs":true,"family":"Banner","given":"J.L.","email":"","affiliations":[],"preferred":false,"id":455269,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Musgrove, MaryLynn 0000-0003-1607-3864","orcid":"https://orcid.org/0000-0003-1607-3864","contributorId":223710,"corporation":false,"usgs":true,"family":"Musgrove","given":"MaryLynn","email":"","affiliations":[{"id":583,"text":"Texas Water Science Center","active":true,"usgs":true}],"preferred":true,"id":455268,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

Our observed hepatic concentration of Se was similar to that reported in lesser scaup collected from the mid-continental United States but less than Se concentrations reported from the Great Lakes region. We found that the liver cadmium (Cd) concentration for males was significantly higher than that for females. Gender differences in hepatic Cd concentrations have not been previously reported for lesser scaup, but Cd is known to have negative impacts on male reproduction. Our results indicate that lesser scaup migrating through the upper Midwest in spring have elevated Se levels and that males carry a significantly greater Cd burden than females. Moreover, elemental concentrations might be high enough to affect reproduction in both male and female lesser scaup, but controlled laboratory studies are needed to adequately assess the effects of Se and Cd on lesser scaup reproduction.</span></p>","language":"English","publisher":"Springer","doi":"10.1007/s00244-010-9587-1","usgsCitation":"Pillatzki, A.E., Neiger, R.D., Chipps, S.R., Higgins,

Consequently, there is a need to evaluate these different techniques. We used spatially-explicit simulation models to compare three spatial Bayesian clustering programs and two edge detection methods. Spatially-structured populations were simulated where a continuous population was subdivided by barriers. We evaluated the ability of each method to correctly identify boundary locations while varying: (i) time after divergence, (ii) strength of isolation by distance, (iii) level of genetic diversity, and (iv) amount of gene flow across barriers. To further evaluate the methods’ effectiveness to detect genetic clusters in natural populations, we used previously published data on North American pumas and a European shrub. Our results show that with simulated and empirical data, the Bayesian spatial clustering algorithms outperformed direct edge detection methods. All methods incorrectly detected boundaries in the presence of strong patterns of isolation by distance. Based on this finding, we support the application of Bayesian spatial clustering algorithms for boundary detection in empirical datasets, with necessary tests for the influence of isolation by distance</span></p>","language":"English","publisher":"MDPI","doi":"10.3390/ijms12020865","issn":"14220067","usgsCitation":"Safner, T., Miller, M.P., McRae, B., Fortin, M., and Manel, S., 2011, Comparison of Bayesian clustering and edge detection methods for inferring boundaries in landscape genetics: International Journal of Molecular Sciences, v. 12, no. 2, p. 865-889, https://doi.org/10.3390/ijms12020865.","productDescription":"25 p.","startPage":"865","endPage":"889","costCenters":[{"id":38131,"text":"WMA - Office of Planning and Programming","active":true,"usgs":true}],"links":[{"id":475131,"rank":1,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.3390/ijms12020865","text":"Publisher Index Page"},{"id":244276,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"12","issue":"2","noUsgsAuthors":false,"publicationDate":"2011-01-25","publicationStatus":"PW","scienceBaseUri":"5059f840e4b0c8380cd4cf8c","contributors":{"authors":[{"text":"Safner, T.","contributorId":35980,"corporation":false,"usgs":true,"family":"Safner","given":"T.","email":"","affiliations":[],"preferred":false,"id":452667,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Miller, Mark P. 0000-0003-1045-1772 mpmiller@usgs.gov","orcid":"https://orcid.org/0000-0003-1045-1772","contributorId":1967,"corporation":false,"usgs":true,"family":"Miller","given":"Mark","email":"mpmiller@usgs.gov","middleInitial":"P.","affiliations":[{"id":38131,"text":"WMA - Office of Planning and Programming","active":true,"usgs":true}],"preferred":true,"id":452669,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"McRae, B.H.","contributorId":41658,"corporation":false,"usgs":true,"family":"McRae","given":"B.H.","email":"","affiliations":[],"preferred":false,"id":452668,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Fortin, M.-J.","contributorId":96489,"corporation":false,"usgs":true,"family":"Fortin","given":"M.-J.","email":"","affiliations":[],"preferred":false,"id":452670,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Manel, S.","contributorId":23785,"corporation":false,"usgs":true,"family":"Manel","given":"S.","affiliations":[],"preferred":false,"id":452666,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}}

Determination of the molecular-level speciation of Hg in soils and mine wastes is important for understanding its sequestration, mobility, and availability for methylation. Extended X-ray absorption fine structure (EXAFS) spectroscopy carried out under ambient P-T conditions has been used in a number of past studies to determine Hg speciation in complex mine wastes and associated soils. However, this approach cannot detect elemental (liquid) mercury in Hg-polluted soils and sediments due to the significant structural disorder of liquid Hg at ambient-temperature. A new sample preparation protocol involving slow cooling through the crystallization temperature of Hg(0) (234 K) results in its transformation to crystalline α-Hg(0). The presence and proportion of Hg(0), relative to other crystalline Hg-bearing phases, in samples prepared in this way can be quantified by low-temperature (77 K) EXAFS spectroscopy. Using this approach, we have determined the relative concentrations of liquid Hg(0) in Hg mine wastes from several sites in the California Coast Range and have found that they correlate well with measured fluxes of gaseous Hg released during light and dark exposure of the same samples, with higher evasion ratios from samples containing higher concentrations of liquid Hg(0). Two different linear relationships are observed in plots of the ratio of Hg emission under light and dark conditions vs % Hg(0), corresponding to silica−carbonate- and hot springs-type Hg deposits, with the hot springs-type samples exhibiting higher evasion fluxes than silica−carbonate type samples at similar Hg(0) concentrations. Our findings help explain significant differences in Hg evasion data for different mine sites in the California Coast Range.</span></p>","language":"English","publisher":"American Chemical Society","doi":"10.1021/es1023527","issn":"0013936X","usgsCitation":"Jew, A., Kim, C., Rytuba, J.J., Gustin, M., and Brown, G.E., 2011, New technique for quantification of elemental hg in mine wastes and its implications for mercury evasion into the atmosphere: Environmental Science & Technology, v. 45, no. 2, p. 412-417, https://doi.org/10.1021/es1023527.","productDescription":"6 p.","startPage":"412","endPage":"417","costCenters":[{"id":312,"text":"Geology, Minerals, Energy, and Geophysics Science Center","active":true,"usgs":true}],"links":[{"id":475110,"rank":1,"type":{"id":41,"text":"Open Access External Repository Page"},"url":"https://europepmc.org/articles/pmc3030447","text":"External Repository"},{"id":244140,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"45","issue":"2","noUsgsAuthors":false,"publicationDate":"2010-12-01","publicationStatus":"PW","scienceBaseUri":"505a661ae4b0c8380cd72d10","contributors":{"authors":[{"text":"Jew, A.D.","contributorId":66090,"corporation":false,"usgs":true,"family":"Jew","given":"A.D.","email":"","affiliations":[],"preferred":false,"id":451984,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Kim, C.S.","contributorId":54365,"corporation":false,"usgs":true,"family":"Kim","given":"C.S.","email":"","affiliations":[],"preferred":false,"id":451983,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Rytuba, James J. jrytuba@usgs.gov","contributorId":3043,"corporation":false,"usgs":true,"family":"Rytuba","given":"James","email":"jrytuba@usgs.gov","middleInitial":"J.","affiliations":[{"id":312,"text":"Geology, Minerals, Energy, and Geophysics Science Center","active":true,"usgs":true}],"preferred":true,"id":451985,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Gustin, M.S.","contributorId":101837,"corporation":false,"usgs":true,"family":"Gustin","given":"M.S.","email":"","affiliations":[],"preferred":false,"id":451986,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Brown, Gordon E.

Approaches are needed to guide decisions that balance human water needs while conserving riparian ecosystems. We developed a space‐for‐time substitution model that links groundwater change scenarios implemented within a Decision Support System (DSS) with proportions of floodplain vegetation types and abundances of breeding and migratory birds along the upper San Pedro River, AZ, USA. We investigated nine scenarios ranging from groundwater depletion to recharge. In groundwater decline scenarios, relative proportions of tall‐canopied obligate phreatophytes (</span><i>Populus/Salix</i><span>, cottonwood/willow) on the floodplain progressively decline, and shrubbier species less dependent on permanent water sources (e.g.&nbsp;</span><i>Tamarix</i><span>&nbsp;spp., saltcedar) increase. These scenarios result in broad shifts in the composition of the breeding bird community, with canopy‐nesting and water‐obligate birds declining but midstory nesting birds increasing in abundance as groundwater declines. For the most extreme draw‐down scenario where all reaches undergo groundwater declines, models project that only 10% of the upper San Pedro floodplain would be comprised of cottonwood/willow (73% saltcedar and 18% mesquite), and abundances of canopy‐nesting, water‐obligate, and spring migrant birds would decline 48%, 72%, and 40%, respectively. Groundwater recharge scenarios were associated with increases in canopy‐nesting birds particularly given the extreme recharge scenario (all reaches regain shallow water tables and perennial streamflow). Model outputs serve to assess the sensitivity of biotic groups to potential changes in groundwater and thus to rank scenarios based on their expected ecological impacts.&nbsp;</span></p>","language":"English","publisher":"Wiley","doi":"10.1002/eco.143","issn":"19360584","usgsCitation":"Arriana, B.L., Stromberg, J., Goodrich, D., Dixon, M., Lansey, K., Kang, D., Brookshire, D., and Cerasale, D., 2011, Projecting avian response to linked changes in groundwater and riparian floodplain vegetation along a dryland river: A scenario analysis: Ecohydrology, v. 4, no. 1, p. 130-142, https://doi.org/10.1002/eco.143.","productDescription":"13 p.","startPage":"130","endPage":"142","costCenters":[],"links":[{"id":243366,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":215554,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1002/eco.143"}],"volume":"4","issue":"1","noUsgsAuthors":false,"publicationDate":"2011-01-19","publicationStatus":"PW","scienceBaseUri":"505a8efbe4b0c8380cd7f4e6","contributors":{"authors":[{"text":"Arriana, Brand L.","contributorId":9488,"corporation":false,"usgs":true,"family":"Arriana","given":"Brand","email":"","middleInitial":"L.","affiliations":[],"preferred":false,"id":450419,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Stromberg, J.C.","contributorId":81455,"corporation":false,"usgs":true,"family":"Stromberg","given":"J.C.","email":"","affiliations":[],"preferred":false,"id":450425,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Goodrich, D.C.","contributorId":98492,"corporation":false,"usgs":false,"family":"Goodrich","given":"D.C.","email":"","affiliations":[],"preferred":false,"id":450426,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Dixon, M.D.","contributorId":57279,"corporation":false,"usgs":true,"family":"Dixon","given":"M.D.","email":"","affiliations":[],"preferred":false,"id":450423,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Lansey, K.","contributorId":57680,"corporation":false,"usgs":true,"family":"Lansey","given":"K.","email":"","affiliations":[],"preferred":false,"id":450424,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Kang, D.","contributorId":19799,"corporation":false,"usgs":true,"family":"Kang","given":"D.","email":"","affiliations":[],"preferred":false,"id":450421,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Brookshire, D.S.","contributorId":43335,"corporation":false,"usgs":true,"family":"Brookshire","given":"D.S.","email":"","affiliations":[],"preferred":false,"id":450422,"contributorType":{"id":1,"text":"Authors"},"rank":7},{"text":"Cerasale, D.J.","contributorId":11028,"corporation":false,"usgs":true,"family":"Cerasale","given":"D.J.","email":"","affiliations":[],"preferred":false,"id":450420,"contributorType":{"id":1,"text":"Authors"},"rank":8}]}}

We surveyed 150 sites in 2006&ndash;2007 to determine if this species still occupied its former breeding range in Oklahoma. We located Cerulean Warblers at 5 sites and confirmed breeding on north slopes of two heavily forested ridges in the Ouachita Mountains. We did not encounter Cerulean Warblers in any bottomland hardwoods, despite the former widespread distribution and abundance of the species in such habitats. While habitat loss and degradation may limit occurrence of Cerulean Warbler in some areas, the pattern of decline for this species at the edge of its range in Oklahoma is also consistent with abandonment of peripheral range as the range-wide population declines.</span></p>","language":"English","publisher":"Eagle Hill Institute","doi":"10.1656/058.010.0114","usgsCitation":"Leslie, D.,

A total of 19 fully penetrating soil cores were collected from a rectangular grid of 4 m by 4 m. Detailed grain size analysis was performed on 5 cm segments of each core, yielding 1740 hydraulic conductivity (</span><i>K</i><span>) estimates. Three different geostatistical simulation methods were used to generate 3‐D conditional realizations of the&nbsp;</span><i>K</i><span>&nbsp;field for the sampled block. Particle tracking calculations showed that the fastest particles, as represented by the first 5% to arrive, converge along preferential flow paths and exit the model domain within preferred areas. These 5% fastest flow paths accounted for about 40% of the flow. The distribution of preferential flow paths and particle exit locations is clearly influenced by the occurrence of clusters formed by interconnected cells with&nbsp;</span><i>K</i><span>&nbsp;equal to or greater than the 0.9 decile of the data distribution (10% of the volume). The fraction of particle paths within the high‐</span><i>K</i><span>&nbsp;clusters ranges from 43% to 69%.

The data set builds on the Aptian–Albian sphaerosiderite δ<sup>18</sup>O data set presented by Ufnar et al. (2002) by incorporating additional low latitude data including pedogenic and early meteoric diagenetic calcite δ<sup>18</sup>O. Ufnar et al. (2002) used the proxy data derived from the North American Cretaceous Western Interior Basin (KWIB) in a mass balance model to estimate precipitation–evaporation fluxes. We have revised this mass balance model to handle sphaerosiderite and calcite proxies, and to account for longitudinal travel by tropical air masses. We use empirical and general circulation model (GCM) temperature gradients for the mid-Cretaceous, and the empirically derived δ<sup>18</sup>O composition of groundwater as constraints in our mass balance model. Precipitation flux, evaporation flux, relative humidity, seawater composition, and continental feedback are adjusted to generate model calculated groundwater δ<sup>18</sup>O compositions (proxy for precipitation δ<sup>18</sup>O) that match the empirically-derived groundwater δ<sup>18</sup>O compositions to within ±&nbsp;0.5‰. The model is calibrated against modern precipitation data sets.</p><p id=\"sp0065\">Four different Cretaceous temperature estimates were used: the leaf physiognomy estimates of Wolfe and Upchurch (1987) and Spicer and Corfield (1992), the coolest and warmest Cretaceous estimates compiled by Barron (1983) and model outputs from the GENESIS-MOM GCM by Zhou et al. (2008). Precipitation and evaporation fluxes for all the Cretaceous temperature gradients utilized in the model are greater than modern precipitation and evaporation fluxes. Balancing the model also requires relative humidity in the subtropical dry belt to be significantly reduced. As expected calculated precipitation rates are all greater than modern precipitation rates. Calculated global average precipitation rates range from 371&nbsp;mm/year to 1196&nbsp;mm/year greater than modern precipitation rates. Model results support the hypothesis that increased rainout produces δ<sup>18</sup>O-depleted precipitation.</p><p id=\"sp0070\">Sensitivity testing of the model indicates that the amount of water vapor in the air mass, and its origin and pathway, significantly affect the oxygen isotopic composition of precipitation. Precipitation δ<sup>18</sup>O is also sensitive to seawater δ<sup>18</sup>O and enriched tropical seawater was necessary to simulate proxy data (consistent with fossil and geologic evidence for a warmer and evaporatively enriched Tethys). Improved constraints in variables such as seawater δ<sup>18</sup>O can help improve boundary conditions for mid-Cretaceous climate simulations.</p>","language":"English","publisher":"Elsevier","doi":"10.1016/j.palaeo.2011.05.027","issn":"00310182","usgsCitation":"Suarez, M., Gonzalez, L.A., and Ludvigson, G.A., 2011, Quantification of a greenhouse hydrologic cycle from equatorial to polar latitudes: The mid-Cretaceous water bearer revisited: Palaeogeography, Palaeoclimatology, Palaeoecology, v. 307, no. 1-4, p. 301-312, https://doi.org/10.1016/j.palaeo.2011.05.027.","productDescription":"12 p.","startPage":"301","endPage":"312","costCenters":[],"links":[{"id":246306,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":218307,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.palaeo.2011.05.027"}],"volume":"307","issue":"1-4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a91a6e4b0c8380cd80398","contributors":{"authors":[{"text":"Suarez, M.B.","contributorId":18589,"corporation":false,"usgs":true,"family":"Suarez","given":"M.B.","email":"","affiliations":[],"preferred":false,"id":454979,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Gonzalez, Luis A.","contributorId":20922,"corporation":false,"usgs":true,"family":"Gonzalez","given":"Luis","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":454980,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Ludvigson, Greg A.","contributorId":80803,"corporation":false,"usgs":true,"family":"Ludvigson","given":"Greg","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":454981,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

This paper reviews several key advancements in both technology and science in the field of currents in submarine canyons since the1979 publication of <i>Currents in Submarine Canyons and Other Sea Valleys by</i> Francis Shepard and colleagues. Precise placements of high-resolution, high-frequency instruments have not only allowed researchers to collect new data that are essential for advancing and generalizing theories governing the canyon currents, but have also revealed new natural phenomena that challenge the understandings of the theorists and experimenters in their predictions of submarine canyon flow fields. Baroclinic motions at tidal frequencies, found to be intensified both up canyon and toward the canyon floor, dominate the flow field and control the sediment transport processes in submarine canyons. Turbidity currents are found to frequently occur in active submarine canyons such as Monterey Canyon. These turbidity currents have maximum speeds of nearly 200 cm/s, much smaller than the speeds of turbidity currents in geological time, but still very destructive. In addition to traditional Eulerian measurements, Lagrangian flow data are essential in quantifying water and sediment transport in submarine canyons. A concerted experiment with multiple monitoring stations along the canyon axis and on nearby shelves is required to characterize the storm-trigger mechanism for turbidity currents.</p>","language":"English","publisher":"Geological Society of America","doi":"10.1130/GES00640.1","issn":"1553040X","usgsCitation":"Xu, J.P., 2011, Measuring currents in submarine canyons: technological and scientific progress in the past 30 years: Geosphere, v. 7, no. 4, p. 868-876, https://doi.org/10.1130/GES00640.1.","productDescription":"9 p.","startPage":"868","endPage":"876","numberOfPages":"9","onlineOnly":"N","additionalOnlineFiles":"N","ipdsId":"IP-025043","costCenters":[],"links":[{"id":475331,"rank":10000,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1130/ges00640.1","text":"Publisher Index Page"},{"id":246275,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":218278,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1130/GES00640.1"}],"volume":"7","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a5346e4b0c8380cd6c981","contributors":{"authors":[{"text":"Xu, J.

A survey of 811 members of the New England Trail Riders Association was conducted in fall 2007; 380 questionnaires were completed and returned. Descriptive statistics and regressions were used to identify relationships between OHV rider attitudes, management preferences, and intentions toward two trail use–related behaviors (i.e., illegal use of trails by OHVs and the creation and/or use of unauthorized trails by OHV riders). Results reveal that the average responding association member has a negative attitude toward the two depreciative behaviors, intends to ride OHVs legally, and slightly prefers indirect over direct forms of management. Significant relationships between intentions and both attitudes and management preferences are identified. Policy and management implications and strategies are discussed.</span></p>","language":"English","publisher":"Oxford Academic","doi":"10.1093/jof/109.5.281","usgsCitation":"Kuehn, D., D’Luhosch, P.D., Luzadis, V., Malmsheimer, R.W., and Schuster, R., 2011, Attitudes and intentions of off-highway vehicle riders toward trail use: Implications for forest managers: Journal of Forestry, v. 109, no. 5, p. 281-287, https://doi.org/10.1093/jof/109.5.281.","productDescription":"7 p.","startPage":"281","endPage":"287","costCenters":[{"id":291,"text":"Fort Collins Science Center","active":true,"usgs":true}],"links":[{"id":489216,"rank":3,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1093/jof/109.5.281","text":"Publisher Index Page"},{"id":246533,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":410940,"rank":2,"type":{"id":15,"text":"Index Page"},"url":"https://academic.oup.com/jof/article/109/5/281/4599468","linkFileType":{"id":5,"text":"html"}}],"volume":"109","issue":"5","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059eed3e4b0c8380cd49fc3","contributors":{"authors":[{"text":"Kuehn, Diane","contributorId":172900,"corporation":false,"usgs":false,"family":"Kuehn","given":"Diane","email":"","affiliations":[],"preferred":false,"id":454447,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"D’Luhosch, P.
