Thus, MS is considerably higher in well-drained soils (MS typically 40-80 ?? 10-5 standard international [SI]) compared to poorly drained soils (MS typically 10-25 ?? 10-5 SI) in Illinois, other soil-forming factors being equal. Following calibration to standard soil probings, MS values can be used to rapidly and precisely delineate hydric from nonhydric soils in areas with relatively uniform parent material. Furthermore, soil MS has a moderate to strong association with individual tree species' distribution across soil moisture regimes, correlating inversely with independently reported rankings of a tree species' flood tolerance. Soil MS mapping can thus provide a simple, rapid, and quantitative means for precisely guiding reforestation with respect to plant species' adaptations to soil drainage classes. For instance, in native woodlands of east-central Illinois, Quercus alba , Prunus serotina, and Liriodendron tulipifera predominantly occur in moderately well-drained soils (MS 40-60 ?? 10-5 SI), whereas Acer saccharinum, Carya laciniosa, and Fraxinus pennsylvanica predominantly occur in poorly drained soils (MS <20 ?? 10-5 SI). Using a similar method, an MS contour map was used to guide restoration of mesic, wet mesic, and wet prairie species to pre-settlement distributions at Meadowbrook Park (Urbana, IL, U.S.A.). Through use of soil MS maps calibrated to soil drainage class and native vegetation occurrence, restoration efforts can be conducted more successfully and species distributions more accurately reconstructed at the microecosystem level. ?? 2008 Society for Ecological Restoration International.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Restoration Ecology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1111/j.1526-100X.2008.00479.x","issn":"10612","usgsCitation":"Grimley, D., Wang, J., Liebert, D., and Dawson, J., 2008, Soil magnetic susceptibility: A quantitative proxy of soil drainage for use in ecological restoration: Restoration Ecology, v. 16, no. 4, p. 657-667, https://doi.org/10.1111/j.1526-100X.2008.00479.x.","startPage":"657","endPage":"667","numberOfPages":"11","costCenters":[],"links":[{"id":241083,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":213457,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1111/j.1526-100X.2008.00479.x"}],"volume":"16","issue":"4","noUsgsAuthors":false,"publicationDate":"2008-11-26","publicationStatus":"PW","scienceBaseUri":"505b9207e4b08c986b319c54","contributors":{"authors":[{"text":"Grimley, D.A.","contributorId":18530,"corporation":false,"usgs":true,"family":"Grimley","given":"D.A.","email":"","affiliations":[],"preferred":false,"id":439244,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Wang, J.-S.","contributorId":67297,"corporation":false,"usgs":true,"family":"Wang","given":"J.-S.","email":"","affiliations":[],"preferred":false,"id":439245,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Liebert, D.A.","contributorId":11010,"corporation":false,"usgs":true,"family":"Liebert","given":"D.A.","email":"","affiliations":[],"preferred":false,"id":439243,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Dawson, J.O.","contributorId":77367,"corporation":false,"usgs":true,"family":"Dawson","given":"J.O.","email":"","affiliations":[],"preferred":false,"id":439246,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

Based on dissolved phosphorus (P) and nitrogen (N) concentrations and N:P ratios, P is typically the limiting nutrient in the Sea and, therefore, should be the primary nutrient of concern when considering management efforts. Flows in the major tributaries to the Sea have been measured since 1965, whereas total P (TP) concentrations were only measured intermittently by various agencies since 1968. These data were used to estimate annual P loading from 1965 to 2002. Annual loads have increased steadily from ???940,000 kg around 1968 to ???1,450,000 kg in 2002 (???55% increase), primarily a result of increased TP concentrations and loads in the New River. Although the eutrophic condition of the Salton Sea is of great concern, only limited nutrient data are available for the Sea. It is difficult to determine whether the eutrophic state of the Sea has degraded or possibly even improved slightly in response to the change in P loading because of variability in the data and changes in the sampling and analytical methodologies. ?? 2008 Springer Science+Business Media B.V.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Hydrobiologia","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1007/s10750-008-9312-5","issn":"00188158","usgsCitation":"Robertson, D.M., Schladow, S., and Holdren, G., 2008, Long-term changes in the phosphorus loading to and trophic state of the Salton Sea, California: Hydrobiologia, v. 604, no. 1, p. 21-36, https://doi.org/10.1007/s10750-008-9312-5.","startPage":"21","endPage":"36","numberOfPages":"16","costCenters":[],"links":[{"id":241605,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":213930,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1007/s10750-008-9312-5"}],"volume":"604","issue":"1","noUsgsAuthors":false,"publicationDate":"2008-03-18","publicationStatus":"PW","scienceBaseUri":"505a497ee4b0c8380cd6865c","contributors":{"authors":[{"text":"Robertson, Dale M. 0000-0001-6799-0596 dzrobert@usgs.gov","orcid":"https://orcid.org/0000-0001-6799-0596","contributorId":150760,"corporation":false,"usgs":true,"family":"Robertson","given":"Dale","email":"dzrobert@usgs.gov","middleInitial":"M.","affiliations":[{"id":37947,"text":"Upper Midwest Water Science Center","active":true,"usgs":true}],"preferred":true,"id":437989,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Schladow, S.G.","contributorId":92791,"corporation":false,"usgs":true,"family":"Schladow","given":"S.G.","email":"","affiliations":[],"preferred":false,"id":437991,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Holdren, G.C.","contributorId":63630,"corporation":false,"usgs":true,"family":"Holdren","given":"G.C.","email":"","affiliations":[],"preferred":false,"id":437990,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

Using data from conventional purging techniques, aquifer test response analysis, chemical analysis, and regression analysis of chloride/silica (Cl/Si) ratio, equations were derived to estimate the volume of saline water intrusion into a well and a porous media aquifer, the volume of water needed to purge a well shortly following an intrusion event, and the volume of water needed after delay of several or more months, when the saline plume has expanded. Purging time required is a function of volume of water and pumping rate. The study site well is located within a shoreline community of Lake Pontchartrain, St. Tammany Parish, in southeastern Louisiana, United States, which was impacted by two hurricane storm surges and had neither been rehabilitated nor chlorinated prior to our study. Chemical analysis of water samples in fall 2005 and purging of well and aquifer in June 6, 2006, indicated saline water had intruded the well in 2005 and the well and aquifer in 2006. The volume of water needed to purge the study well was approximately 200 casing volumes, which is significantly greater than conventionally used during collection of water samples for water quality analyses. ?? 2007 National Ground Water Association.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Ground Water","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1111/j.1745-6584.2007.00380.x","issn":"0017467X","usgsCitation":"Carlson, D., Van Biersel, T.P., and Milner, L., 2008, Storm-damaged saline-contaminated boreholes as a means of aquifer contamination: Ground Water, v. 46, no. 1, p. 69-79, https://doi.org/10.1111/j.1745-6584.2007.00380.x.","startPage":"69","endPage":"79","numberOfPages":"11","costCenters":[],"links":[{"id":214492,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1111/j.1745-6584.2007.00380.x"},{"id":242224,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"46","issue":"1","noUsgsAuthors":false,"publicationDate":"2007-10-30","publicationStatus":"PW","scienceBaseUri":"505b987ce4b08c986b31c05e","contributors":{"authors":[{"text":"Carlson, D.A.","contributorId":56856,"corporation":false,"usgs":true,"family":"Carlson","given":"D.A.","email":"","affiliations":[],"preferred":false,"id":441968,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Van Biersel, T.

Carbonate-bearing rocks had not previously been detected on Mars' surface, but Mars Reconnaissance Orbiter mapping reveals a regional rock layer with near-infrared spectral characteristics that are consistent with the presence of magnesium carbonate in the Nili Fossae region. The carbonate is closely associated with both phyllosilicate-bearing and olivine-rich rock units and probably formed during the Noachian or early Hesperian era from the alteration of olivine by either hydrothermal fluids or near-surface water. The presence of carbonate as well as accompanying clays suggests that waters were neutral to alkaline at the time of its formation and that acidic weathering, proposed to be characteristic of Hesperian Mars, did not destroy these carbonates and thus did not dominate all aqueous environments.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Science","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1126/science.1164759","issn":"00368","usgsCitation":"Ehlmann, B., Mustard, J., Murchie, S., Poulet, F., Bishop, J., Brown, A., Calvin, W.M., Clark, R.N., Des Marais, D., Milliken, R., Roach, L., Roush, T.L., Swayze, G., and Wray, J., 2008, Orbital identification of carbonate-bearing rocks on Mars: Science, v. 322, no. 5909, p. 1828-1832, https://doi.org/10.1126/science.1164759.","startPage":"1828","endPage":"1832","numberOfPages":"5","costCenters":[],"links":[{"id":476679,"rank":10000,"type":{"id":41,"text":"Open Access External Repository Page"},"url":"https://resolver.caltech.edu/CaltechAUTHORS:20121016-112524059","text":"External Repository"},{"id":213490,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1126/science.1164759"},{"id":241117,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"322","issue":"5909","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a6f2fe4b0c8380cd759a6","contributors":{"authors":[{"text":"Ehlmann, B.L.","contributorId":107837,"corporation":false,"usgs":true,"family":"Ehlmann","given":"B.L.","email":"","affiliations":[],"preferred":false,"id":439267,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Mustard, J.F.","contributorId":91605,"corporation":false,"usgs":true,"family":"Mustard","given":"J.F.","email":"","affiliations":[],"preferred":false,"id":439265,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Murchie, S.L.","contributorId":7369,"corporation":false,"usgs":true,"family":"Murchie","given":"S.L.","email":"","affiliations":[],"preferred":false,"id":439255,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Poulet, F.","contributorId":61551,"corporation":false,"usgs":true,"family":"Poulet","given":"F.","email":"","affiliations":[],"preferred":false,"id":439260,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Bishop, J.L.","contributorId":83244,"corporation":false,"usgs":true,"family":"Bishop","given":"J.L.","affiliations":[],"preferred":false,"id":439263,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Brown, A.J.","contributorId":54803,"corporation":false,"usgs":true,"family":"Brown","given":"A.J.","email":"","affiliations":[],"preferred":false,"id":439259,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Calvin, W.

The sand volume is too large to be accounted for simply by erosion in observed river channels or ejecta from observed impact craters. The lakes are adequate in extent to buffer atmospheric methane against photolysis in the short term, but do not contain enough methane to sustain the atmosphere over geologic time.

To our knowledge, no reports are available on baseline hepatic mineral concentrations from sympatric white-tailed deer (Odocoileus virginianus) and mule deer (Odocoileus hemionus) using different habitats in the Northern Great Plains. We assessed variation in hepatic minerals of female white-tailed deer (n=42) and mule deer (n=41). Deer were collected in February and August 2002 and 2003 from study areas in Custer and Pennington Counties, South Dakota, in and adjacent to a wildfire burn. Hepatic samples were tested for levels (parts per million; ppm) of aluminum (Al), antimony (Sb), arsenic (As), barium (Ba), boron (B), cadmium (Cd), calcium (Ca), chromium (Cr), cobalt (Co), copper (Cu), iron (Fe), lead (Pb), magnesium (Mg), manganese (Mn), mercury (Hg), molybdenum (Mo), nickel (Ni), phosphorus (P), potassium (K), selenium (Se), sodium (Na), sulfur (S), thalium (T1), and zinc (Zn). We predicted that variability in element concentrations would occur between burned and unburned habitat due to changes in plant communities and thereby forage availability. We determined that Zn, Cu, and Ba values differed (P???0.05) between habitats. Because of the nutritional demands of gestation and lactation, we hypothesized that elemental concentrations would vary depending on reproductive status; Cd, Cu, Ca, P, Mn, Mo, Na, and Zn values differed (P???0.05) by reproductive status. We also hypothesized that, due to variation in feeding strategies and morphology between deer species, hepatic elemental concentrations would reflect dietary differences; Ca, Cu, K, Co, Mo, Se, and Zn differed (P???0.05) between species. Further research is needed to determine causes of variation in hepatic mineral levels due to habitat, reproductive status, and species. ??

Currently, beach contamination study approaches tend to be site-specific underthe belief that politically delineated beaches are unique and management of beaches cannot be regionally oriented. E. coli data collected over five years from 23 Chicago beaches clearly identified ambient linked patterns at the regional scale. Temporal fluctuations were similar, with all beaches having simultaneous peaks and troughs of E. coli concentrations. Spatially, E. coli concentrations for beaches more closely situated were more closely correlated, indicating spatial autocorrelation. Julian day, wave height, and barometric pressure explained up to 40% of the variation, a value comparable to individual, less parsimonious site-specific models. Day of sampling could explain the majority of the variation in E. coli concentrations, more so than beach, depth, or time of day. Comparing beaches along a targeted coastline allows a better understanding of inherent background regional fluctuations and, ultimately, better predictions of E. coli concentrations in coastal recreational water.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Environmental Science and Technology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1021/es8019758","issn":"00139","usgsCitation":"Whitman, R., and Nevers, M., 2008, Summer E. coli patterns and responses along 23 Chicago beaches: Environmental Science & Technology, v. 42, no. 24, p. 9217-9224, https://doi.org/10.1021/es8019758.","startPage":"9217","endPage":"9224","numberOfPages":"8","costCenters":[],"links":[{"id":241774,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":214085,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1021/es8019758"}],"volume":"42","issue":"24","noUsgsAuthors":false,"publicationDate":"2008-11-14","publicationStatus":"PW","scienceBaseUri":"505b9f32e4b08c986b31e3dc","contributors":{"authors":[{"text":"Whitman, R.L.","contributorId":69750,"corporation":false,"usgs":true,"family":"Whitman","given":"R.L.","email":"","affiliations":[],"preferred":false,"id":437884,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Nevers, M.B.","contributorId":13787,"corporation":false,"usgs":true,"family":"Nevers","given":"M.B.","email":"","affiliations":[],"preferred":false,"id":437883,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

Contamination issues are a major concern because these conduits are characterized by direct connections to sinking streams, high groundwater velocities, and proximity to public water supplies. Objectives of the study were to estimate approximate conduit locations and assess possible anthropogenic influences associated with conduits. Anomalies of young groundwater based on chlorofluorocarbons (CFCs), tritium, and electrical conductivity (EC) indicated fast moving, focused flow and thus the likely presence of conduits. ??18O was useful for determining sources of recharge for each conduit, and nitrate was a useful tracer for assessing flow paths for anthropogenic influences. Two of the four conduits terminate at or near a large spring complex. CFC apparent ages ranged from 15 years near conduits to >50 years in other areas. Nitrate-N concentrations >0.4 mg/L in groundwater were associated with each of the four conduits compared with concentrations ranging from <0.1 to 0.4 mg/L in other areas. These higher nitrate-N concentrations probably do not result from sinking streams but rather from other areas of infiltration. ??

Under ideal conditions, the minimum energy required to separate CO2 from post-combustion flue gas and produce pure CO2 at 1 atmospheric pressure was only about 1183 kJ/kg CO2. This amount could double with the addition of the driving forces of mass and heat transfer and the adverse impacts of absorption heat release on adsorption capacity. Thermodynamic analyses were also performed for the aqueous amine-based absorption process. Two CO2 reaction mechanisms, the carbamate formation reaction with primary/secondary amines and the CO2 hydration reaction with tertiary amines, were included in the absorption reaction. The reaction heat, sensible heat, and stripping heat were all important to the total heat requirement. The heat use of an ideal tertiary amine amounted to 2786 kJ/kg, compared to 3211 kJ/kg for an ideal primary amine. The heat usage of an ideal amine was about 20% lower than that of commercially available amines. Optimizing the absorption process configuration could further reduce energy use.

Trace metals in corals can be used to quantify and monitor the impact of these land-based activities. Surface coral samples from the MACR were investigated for trace metal signatures resulting from relative differences in water quality. Samples were analyzed at three spatial scales (colony, reef, and regional) as part of a hierarchical multi-scale survey. A primary goal of the paper is to elucidate the extrapolation of information between fine-scale variation at the colony or reef scale and broad-scale patterns at the regional scale. Of the 18 metals measured, five yielded statistical differences at the colony and/or reef scale, suggesting fine-scale spatial heterogeneity not conducive to regional interpretation. Five metals yielded a statistical difference at the regional scale with an absence of a statistical difference at either the colony or reef scale. These metals are barium (Ba), manganese (Mn), chromium (Cr), copper (Cu), and antimony (Sb). The most robust geochemical indicators of land-based activities are coral Ba and Mn concentrations, which are elevated in samples from the southern region of the Gulf of Honduras relative to those from the Turneffe Islands. These findings are consistent with the occurrence of the most significant watersheds in the MACR from southern Belize to Honduras, which contribute sediment-laden freshwater to the coastal zone primarily as a result of human alteration to the landscape (e.g., deforestation and agricultural practices). Elevated levels of Cu and Sb were found in samples from Honduras and may be linked to industrial shipping activities where copper-antimony additives are commonly used in antifouling paints. Results from this study strongly demonstrate the impact of terrestrial runoff and anthropogenic activities on coastal water quality in the MACR. ?? 2008 Springer-Verlag.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Coral Reefs","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1007/s00338-008-0413-4","issn":"07224","usgsCitation":"Prouty, N., Hughen, K., and Carilli, J., 2008, Geochemical signature of land-based activities in Caribbean coral surface samples: Coral Reefs, v. 27, no. 4, p. 727-742, https://doi.org/10.1007/s00338-008-0413-4.","startPage":"727","endPage":"742","numberOfPages":"16","costCenters":[],"links":[{"id":241739,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":214052,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1007/s00338-008-0413-4"}],"volume":"27","issue":"4","noUsgsAuthors":false,"publicationDate":"2008-08-22","publicationStatus":"PW","scienceBaseUri":"505a16a3e4b0c8380cd551fe","contributors":{"authors":[{"text":"Prouty, N.G.","contributorId":36766,"corporation":false,"usgs":true,"family":"Prouty","given":"N.G.","email":"","affiliations":[],"preferred":false,"id":437871,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Hughen, K.A.","contributorId":69372,"corporation":false,"usgs":true,"family":"Hughen","given":"K.A.","affiliations":[],"preferred":false,"id":437872,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Carilli, J.","contributorId":100625,"corporation":false,"usgs":true,"family":"Carilli","given":"J.","email":"","affiliations":[],"preferred":false,"id":437873,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

We found that severely degraded mangrove stands could not regenerate naturally without human intervention due to severely altered local environments, whereas some native species had been recruited into the 4-10 year S. apetala plantations. In the first 10 years, the exotic species S. apetala grew better than native species such as Rhizophora stylosa Griff and Kandelia candel (Linn.) Druce. The mangrove plantation gradually affected soil physical and chemical properties during its recovery. The exotic S. apetala was more competitive than native species and its plantation was able to restore soil organic matter in about 14 years. Thus, S. apetala can be considered as a pioneer species to improve degraded habitats to facilitate recolonisation by native mangrove species. However, removal to control proliferation may be needed at late stages to facilitate growth of native species. To ensure sustainability of mangroves in South China, the existing mangrove wetlands must be managed as an ecosystem, with long-term scientific monitoring program in place. ?? 2007 The Ecological Society of Japan.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Ecological Research","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1007/s11284-007-0393-9","issn":"09123814","usgsCitation":"Ren, H., Jian, S., Lu, H., Zhang, Q., Shen, W., Han, W., Yin, Z., and Guo, Q., 2008, Restoration of mangrove plantations and colonisation by native species in Leizhou bay, South China: Ecological Research, v. 23, no. 2, p. 401-407, https://doi.org/10.1007/s11284-007-0393-9.","startPage":"401","endPage":"407","numberOfPages":"7","costCenters":[],"links":[{"id":212514,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1007/s11284-007-0393-9"},{"id":240009,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"23","issue":"2","noUsgsAuthors":false,"publicationDate":"2007-06-27","publicationStatus":"PW","scienceBaseUri":"505aaacce4b0c8380cd8652b","contributors":{"authors":[{"text":"Ren, H.","contributorId":45273,"corporation":false,"usgs":true,"family":"Ren","given":"H.","email":"","affiliations":[],"preferred":false,"id":432881,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Jian, S.","contributorId":20977,"corporation":false,"usgs":true,"family":"Jian","given":"S.","email":"","affiliations":[],"preferred":false,"id":432880,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Lu, H.","contributorId":49936,"corporation":false,"usgs":true,"family":"Lu","given":"H.","email":"","affiliations":[],"preferred":false,"id":432882,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Zhang, Q.","contributorId":84163,"corporation":false,"usgs":true,"family":"Zhang","given":"Q.","email":"","affiliations":[],"preferred":false,"id":432885,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Shen, W.","contributorId":71386,"corporation":false,"usgs":true,"family":"Shen","given":"W.","email":"","affiliations":[],"preferred":false,"id":432884,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Han, W.","contributorId":7911,"corporation":false,"usgs":true,"family":"Han","given":"W.","email":"","affiliations":[],"preferred":false,"id":432879,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Yin, Z.","contributorId":108077,"corporation":false,"usgs":true,"family":"Yin","given":"Z.","email":"","affiliations":[],"preferred":false,"id":432886,"contributorType":{"id":1,"text":"Authors"},"rank":7},{"text":"Guo, Q.","contributorId":67039,"corporation":false,"usgs":true,"family":"Guo","given":"Q.","email":"","affiliations":[],"preferred":false,"id":432883,"contributorType":{"id":1,"text":"Authors"},"rank":8}]}}

Modeled groundwater CO2, verified by measurements of recent samples, increased from 10-2.05 atm to 10-1.94 atm, about a 20% increase, from 1991 to 2005. The measured groundwater alkalinity and alkaline-earth element concentrations also increased over that time period. We propose that carbonate minerals dissolve in response to lowered pH that occurs during an annual carbonate-mineral saturation cycle. The cycle starts with low saturation during late summer and autumn when dissolved CO2 is high. As dissolved CO2 decreases in the spring and early summer, carbonates become oversaturated, but oversaturation does not exceed the threshold for precipitation. We propose that groundwater is a CO2 sink through weathering of limestone: soil-generated CO2 is transformed to alkalinity through dissolution of calcite or dolomite. The annual cycle and long-term increase in shallow groundwater CO2 is similar to, but greater than, atmospheric CO2. ?? 2008 Elsevier Ltd.

In contrast, acetylene is only a trace component of Earth's current atmosphere. Nonetheless, a methane-rich atmosphere has been hypothesized for early Earth; this atmosphere would also have been rich in acetylene. This poses a paradox, because acetylene is a potent inhibitor of many key anaerobic microbial processes, including methanogenesis, anaerobic methane oxidation, nitrogen fixation, and hydrogen oxidation. Fermentation of acetylene was discovered ∼25 years ago, and&nbsp;<i>Pelobacter acetylenicus</i>was shown to grow on acetylene by virtue of acetylene hydratase, which results in the formation of acetaldehyde. Acetaldehyde subsequently dismutates to ethanol and acetate (plus some hydrogen). However, acetylene hydratase is specific for acetylene and does not react with any analogous compounds. We hypothesize that microbes with acetylene hydratase played a key role in the evolution of Earth's early biosphere by exploiting an available source of carbon from the atmosphere and in so doing formed protective niches that allowed for other microbial processes to flourish.

The model forcing functions consist of tidal elevations along the open boundaries and freshwater inflows from the main stream and major tributaries in the Danshuei River estuarine system. The bottom friction coefficient was adjusted to achieve model calibration and verification in model simulations of barotropic and baroclinic flows. The turbulent diffusivities were ascertained through comparison of simulated salinity time series with observations. The model simulation results are in qualitative agreement with the available field data. The validated model was then used to investigate the influence of wind stress and freshwater discharge on Dasnhuei River plume. As the absence of wind stress, the anticyclonic circulation is prevailed along the north to west coast. The model results reveal when winds are downwelling-favorable, the surface low-salinity waters are flushed out and move to southwest coast. Conversely, large amounts of low-salinity water flushed out the Danshuei River mouth during upwelling-favorable winds, as the buoyancy-driven circulation is reversed. Wind stress and freshwater discharge are shown to control the plume structure. ?? 2007 Elsevier Inc.

Additionally, there is an increasing demand for multidisciplinary studies that include interactions between different physical processes. Therefore there is a strong desire to develop coupled modeling systems that utilize existing models and allow efficient data exchange and model control. The basic system would entail model \"1\" running on \"M\" processors and model \"2\" running on \"N\" processors, with efficient exchange of model fields at predetermined synchronization intervals. Here we demonstrate two coupled systems: the coupling of the ocean circulation model Regional Ocean Modeling System (ROMS) to the surface wave model Simulating WAves Nearshore (SWAN), and the coupling of ROMS to the atmospheric model Coupled Ocean Atmosphere Prediction System (COAMPS). Both coupled systems use the Model Coupling Toolkit (MCT) as a mechanism for operation control and inter-model distributed memory transfer of model variables. In this paper we describe requirements and other options for model coupling, explain the MCT library, ROMS, SWAN and COAMPS models, methods for grid decomposition and sparse matrix interpolation, and provide an example from each coupled system. Methods presented in this paper are clearly applicable for coupling of other types of models. ?? 2008 Elsevier Ltd.

The framework is based on a univariate regression model that leads to an alternative expression for Horton ratio, connects Horton regression statistics to distributional simple scaling, and improves the accuracy in estimating Horton plot parameters. The model is used to examine data for drainage area A and mainstream length L from two groups of basins located in different physiographic settings. Results show that confidence intervals for the Horton plot regression statistics are quite wide. Nonetheless, an analysis of covariance shows that regression intercepts, but not regression slopes, can be used to distinguish between basin groups. The univariate model is generalized to include n > 1 dependent variables. For the case where the dependent variables represent ln A and ln L, the generalized model performs somewhat better at distinguishing between basin groups than two separate univariate models. The generalized model leads to a modification of Hack's law where L depends on both A and Strahler order ??. Data show that ?? plays a statistically significant role in the modified Hack's law expression. ?? 2008 Elsevier B.V.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Geomorphology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1016/j.geomorph.2008.06.002","issn":"01695","usgsCitation":"Furey, P., and Troutman, B., 2008, A consistent framework for Horton regression statistics that leads to a modified Hack's law: Geomorphology, v. 102, no. 3-4, p. 603-614, https://doi.org/10.1016/j.geomorph.2008.06.002.","startPage":"603","endPage":"614","numberOfPages":"12","costCenters":[],"links":[{"id":214050,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.geomorph.2008.06.002"},{"id":241737,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"102","issue":"3-4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059e396e4b0c8380cd460fc","contributors":{"authors":[{"text":"Furey, P.R.","contributorId":11015,"corporation":false,"usgs":true,"family":"Furey","given":"P.R.","email":"","affiliations":[],"preferred":false,"id":437706,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Troutman, B.M.","contributorId":73638,"corporation":false,"usgs":true,"family":"Troutman","given":"B.M.","email":"","affiliations":[],"preferred":false,"id":437707,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}
