This paper focuses on such a transition during the largest eruption of the twentieth century, the 1912 eruption of Novarupta. The transition is recorded in a dacite block bed, which covers an elliptical area of 4 km2 around the vent. Approximately 700 studied blocks fall into four main lithologic categories: (1) pumiceous, (2) dense, (3) flow-banded dacites, and (4) welded breccias. Textural analyses of the blocks indicate portions of the melt underwent highly variable degrees of outgassing. Vesicle populations show features characteristic of bubble coalescence and collapse. A decrease in measured vesicularity and increased evidence for bubble collapse compared with pumice from earlier Plinian episodes mark the transition from closed- to open-system degassing. Block morphology and textures strongly suggest the magma was first erupted as a relatively gas-rich lava dome/plug, but incomplete out-gassing led to explosive disruption. Heterogeneous degassing of ascending magma began in Plinian Episode III and resulted in instability during Episode IV dome growth and a (series of) Vulcanian explosion(s). Modeling of the dynamics of explosion initiation and ejecta dispersal indicates that a significant concentration in gas is required to produce the explosions responsible for the observed block field dispersal. The amount of gas available in the hot pumiceous dome material appears to have been inadequate to drive the explosion(s); therefore, external water most likely contributed to the destruction. ?? 2006 Geological Society of America.</p>","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Geological Society of America Bulletin","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1130/B25768.1","issn":"00167606","usgsCitation":"Adams, N., Houghton, B.F., Fagents, S., and Hildreth, W., 2006, The transition from explosive to effusive eruptive regime: The example of the 1912 Novarupta eruption, Alaska: Geological Society of America Bulletin, v. 118, no. 5-6, p. 620-634, https://doi.org/10.1130/B25768.1.","startPage":"620","endPage":"634","numberOfPages":"15","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[{"id":615,"text":"Volcano Hazards Program","active":true,"usgs":true}],"links":[{"id":239162,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":211801,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1130/B25768.1"}],"volume":"118","issue":"5-6","noUsgsAuthors":false,"publicationDate":"2006-05-08","publicationStatus":"PW","scienceBaseUri":"505bb138e4b08c986b32527e","contributors":{"authors":[{"text":"Adams, N.K.","contributorId":83729,"corporation":false,"usgs":true,"family":"Adams","given":"N.K.","email":"","affiliations":[],"preferred":false,"id":426431,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Houghton, Bruce F. 0000-0002-7532-9770","orcid":"https://orcid.org/0000-0002-7532-9770","contributorId":140077,"corporation":false,"usgs":false,"family":"Houghton","given":"Bruce","email":"","middleInitial":"F.","affiliations":[{"id":13351,"text":"University of Hawaii Cooperative Studies Unit","active":true,"usgs":false},{"id":6977,"text":"University of Hawai`i at Hilo","active":true,"usgs":false}],"preferred":false,"id":426429,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Fagents, S.A.","contributorId":58840,"corporation":false,"usgs":true,"family":"Fagents","given":"S.A.","email":"","affiliations":[],"preferred":false,"id":426430,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Hildreth, W. 0000-0002-7925-4251","orcid":"https://orcid.org/0000-0002-7925-4251","contributorId":100487,"corporation":false,"usgs":true,"family":"Hildreth","given":"W.","affiliations":[],"preferred":false,"id":426432,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

Profiles of temperature, conductivity, and selected element concentrations were measured almost monthly during 1999 and 2000.

Seasonal surface inflow due to spring snowmelt resulted in lower conductivity in the surface water (232–247&nbsp;μS/cm) relative to deeper water (315–318&nbsp;μS/cm). The pit lake was thermally stratified from late spring through early fall, and the water column turned over in late November (2000) or early December (1999). The pit lake is a mixture of inflowing surface water and groundwater that has subsequently been evapoconcentrated in the arid environment. Linear relationships between conductivity and major and some minor (B, Li, Sr, and U) ions indicate conservative mixing for these elements.</p>","language":"English","publisher":"Elsevier","doi":"10.1016/j.apgeochem.2006.03.013","issn":"08832927","usgsCitation":"Balistrieri, L.S., Tempel, R., Stillings, L., and Shevenell, L., 2006, Modeling spatial and temporal variations in temperature and salinity during stratification and overturn in Dexter Pit Lake, Tuscarora, Nevada, USA: Applied Geochemistry, v. 21, no. 7, p. 1184-1203, https://doi.org/10.1016/j.apgeochem.2006.03.013.","productDescription":"20 p.","startPage":"1184","endPage":"1203","costCenters":[{"id":191,"text":"Colorado Water Science Center","active":true,"usgs":true},{"id":200,"text":"Coop Res Unit Seattle","active":true,"usgs":true},{"id":312,"text":"Geology, Minerals, Energy, and Geophysics Science Center","active":true,"usgs":true}],"links":[{"id":237302,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":210397,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.apgeochem.2006.03.013"}],"country":"United States","state":"Nevada","city":"Tuscarora","otherGeospatial":"Dexter Pit Lake","volume":"21","issue":"7","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a5c2fe4b0c8380cd6fac2","contributors":{"authors":[{"text":"Balistrieri, Laurie S. 0000-0002-6359-3849 balistri@usgs.gov","orcid":"https://orcid.org/0000-0002-6359-3849","contributorId":1406,"corporation":false,"usgs":true,"family":"Balistrieri","given":"Laurie","email":"balistri@usgs.gov","middleInitial":"S.","affiliations":[{"id":191,"text":"Colorado Water Science Center","active":true,"usgs":true},{"id":200,"text":"Coop Res Unit Seattle","active":true,"usgs":true},{"id":662,"text":"Western Mineral and Environmental Resources Science Center","active":true,"usgs":true},{"id":312,"text":"Geology, Minerals, Energy, and Geophysics Science Center","active":true,"usgs":true}],"preferred":true,"id":761872,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Tempel, R.N.","contributorId":47153,"corporation":false,"usgs":true,"family":"Tempel","given":"R.N.","email":"","affiliations":[],"preferred":false,"id":417039,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Stillings, L.L.","contributorId":52229,"corporation":false,"usgs":true,"family":"Stillings","given":"L.L.","email":"","affiliations":[],"preferred":false,"id":417040,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Shevenell, L.A.","contributorId":13777,"corporation":false,"usgs":true,"family":"Shevenell","given":"L.A.","email":"","affiliations":[],"preferred":false,"id":417038,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

Many of these embayments also contain pockmark fields, with some exhibiting geologically active characteristics including the observance of plumes of escaping fluids and sediment. Pockmarks, hemispherically shaped depressions of various size and depths, formed through fluid escape of gas and/or pore water, are sometimes found within or outside gas fields, although many gas fields lack pockmarks altogether. Although the origin of the natural gas remains unclear, if coastal environments at times of lower sea level were similar to the present, numerous lake, wetland, valley fill and estuarine sources of organic-rich material may have formed on the inner shelf. If these deposits survived transgression and remain buried, they are potential gas sources. Intensive mapping of the Belfast Bay pockmark field in 1998 produced the first nearly continuous side scan sonar mosaic of a Gulf of Maine pockmark field with a corresponding 3-dimensional geological model generated from seismic data. Statistical analysis of pockmark geometry, gas deposit loci, and subsurface evidence for gas-enhanced reflectors suggest that gas migration from deeper lateral sources along permeable subsurface strata may be the mechanism for pockmark formation in areas lacking gas-curtain seismic reflections. The coarse-grained transgressive ravinement unconformity between Pleistocene glacial-marine mud and Holocene mud may act as a conduit for distributing methane to the field's margins. ?? 2005 Elsevier B.V.

Once an epizootic begins, contamination of the wetland environment likely facilitates the transmission of P. multocida to susceptible birds. To evaluate the ability of P. multocida serotype-1, the most common serotype associated with avian cholera in waterfowl in western and central North America, to persist in wetlands and to identify environmental factors associated with its persistence, we collected water and sediment samples from 23 wetlands during winters and springs of 1996a??99. These samples were collected during avian cholera outbreaks and for up to 13 wk following initial sampling. We recovered P. multocida from six wetlands that were sampled following the initial outbreaks, but no P. multocida was isolated later than 7 wk after the initial outbreak sampling. We found no significant relationship between the probability of recovery of P. multocida during resampling and the abundance of the bacterium recovered during initial sampling, the substrate from which isolates were collected, isolate virulence, or water quality conditions previously suggested to be related to the abundance or survival of P. multocida. Our results indicate that wetlands are unlikely to serve as a long-term reservoir for P. multocida because the bacterium does not persist in wetlands for long time periods following avian cholera

Long-lived vertebrates such as turtles may be at risk from such events, inasmuch as their life histories preclude rapid recovery should extensive mortality occur. We applied capture&ndash;mark&ndash;recapture models to assess disturbance effects on a population of Florida box turtles (</span><i>Terrapene carolina bauri</i><span>) on Egmont Key, Florida, USA. Near the midpoint of the study, a series of physical disturbances affected the island, from salt water overwash associated with several tropical storms to extensive removal of nonindigenous vegetation. These disturbances allowed us to examine demographic responses of the turtle population and to determine if they affected dispersal throughout the island. Adult survival rates did not vary significantly either between sexes or among years of the study. Survival rates did not vary significantly between juvenile and adult turtles, or among years of the study. Furthermore, neither adult nor juvenile survival rates differed significantly between pre- and post-disturbance. However, dispersal rates varied significantly among the four major study sites, and dispersal rates were higher during the pre-disturbance sampling periods compared to post-disturbance. Our results suggest few long-term effects on the demography of the turtle population. Florida box turtles responded to tropical storms and vegetation control by moving to favorable habitats minimally affected by the disturbances and remaining there. As long as turtles and perhaps other long-lived vertebrates can disperse to non-disturbed habitat, and high levels of mortality do not occur in a population, a long life span may allow them to wait out the impact of disturbance with potentially little effect on long-term population processes.</span><br /><span><br /></span></p>","language":"English","publisher":"Ecological Society of America","doi":"10.1890/1051-0761(2006)016[1936:TIODEO]2.0.CO;2","usgsCitation":"Dodd, C., Ozgul, A., and Oli, M., 2006, The influence of disturbance events on survival and dispersal rates of Florida box turtles: Ecological Applications, v. 16, no. 5, p. 1936-1944, https://doi.org/10.1890/1051-0761(2006)016[1936:TIODEO]2.0.CO;2.","productDescription":"9 p.","startPage":"1936","endPage":"1944","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[],"links":[{"id":132674,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"16","issue":"5","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4affe4b07f02db697d53","contributors":{"authors":[{"text":"Dodd, C.K.

However, stocking grass carp presents several problems including complete eradication of submersed aquatic vegetation, dispersal out of the target area, adverse effects on fish communities, and damage to waterfowl habitat and native vegetation. The purpose of this research was to consider the feasibility of an implantable capsule for limiting the lifespan of grass carp. Stainless steel dowel pins were inserted into 49 fish to identify the most appropriate site to implant the capsule. The throat region along the body's longitudinal axis was identified as the most suitable location because it resulted in minimal loss over an 8-month holding period. Rotenone solutions were injected into the ventral surface between the pelvic fins to determine the lethal dosage to 95% of the population (LD 95). The LD95 for grass carp increased curvilin-early with fish weight. Four polymers that merit further evaluation in constructing the capsule are poly[bis(p-carboxyphenoxy) propane anhydride], poly[bis(p- carboxyphenoxy) hexane anhydride], poly-1-lactide, and poly(??-caprolactone) . Implants are commonly used to deliver pharmaceutical products in medical and veterinarian applications, and have been used in fish. Developing a bioerodible capsule could increase the safety and flexibility of stocking grass carp for control of aquatic plants, and may also be applicable for management of other exotic species.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Aquatic Plant Management","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","issn":"01466623","usgsCitation":"Thomas, R., Miranda, L., and Kirk, J., 2006, Feasibility of an implantable capsule for limiting lifespan of grass carp: Journal of Aquatic Plant Management, v. 44, no.

We studied clones of four species of emergent marsh macrophytes native to the northern coast of the Gulf of Mexico in Louisiana, USA, to examine variation in response to salinity and flooding stress under controlled greenhouse conditions. Clones of Distichlis spicata, Phragmites australis, Schoenoplectus californicus, and Schoenoplectus robustus were collected across the coastal zone of Louisiana. After vegetative propagation through at least three generations to remove acclimation to field conditions, four to six clones of each species were selected for use in the experiment. Treatments consisted of three salinity levels and two water depths, and species were assigned to either a brackish marsh (P. australis, S. californicus) or salt marsh (D. spicata, S. robustus) group for treatment application. Treatment effects on plant growth (stem number, total height, and mean height, and aboveground and belowground biomass) were examined, and physicochemical characteristics within treatments (redox potential, and interstitial water pH, salinity, temperature, and nutrients) were monitored. Clonal variation in growth was indicated in all species, and was more pronounced in D. spicata and P. australis than in S. californicus and S. robustus. Distichlis spicata and P. australis clones were assigned to relative categories of low, intermediate, and high tolerance to the imposed stressors. Similar generalizations on clonal stress tolerance were not possible for the two Schoenoplectus species. Overall species response to imposed stressors was also identified through non-statistical comparisons. Phragmites australis was more tolerant than S. californicus of increased salinity. Distichlis spicata was more tolerant of increased salinity but less tolerant of increased water depth than was S. robustus. Our results suggest that information on species and clone variations in growth and tolerance to salinity and flooding stressors can be used to select a variety of plant materials suitable for wetland restoration projects.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Environmental and Experimental Botany","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1016/j.envexpbot.2005.03.003","issn":"00988472","usgsCitation":"Howard, R., and Rafferty, P., 2006, Clonal variation in response to salinity and flooding stress in four marsh macrophytes of the northern gulf of Mexico, USA: Environmental and Experimental Botany, v. 56, no. 3, p. 301-313, https://doi.org/10.1016/j.envexpbot.2005.03.003.","startPage":"301","endPage":"313","numberOfPages":"13","costCenters":[],"links":[{"id":210417,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.envexpbot.2005.03.003"},{"id":237327,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"56","issue":"3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059f672e4b0c8380cd4c77c","contributors":{"authors":[{"text":"Howard, R.J. 0000-0001-7264-4364","orcid":"https://orcid.org/0000-0001-7264-4364","contributorId":86452,"corporation":false,"usgs":true,"family":"Howard","given":"R.J.","affiliations":[{"id":17705,"text":"Wetland and Aquatic Research Center","active":true,"usgs":true}],"preferred":false,"id":416415,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Rafferty, P.S.","contributorId":86959,"corporation":false,"usgs":true,"family":"Rafferty","given":"P.S.","email":"","affiliations":[],"preferred":false,"id":416416,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

This finding suggests that management priorities could focus on coastal sources as a first course of action. This would require management constraints on a much smaller population.</span></p>","language":"English","publisher":"Springer","doi":"10.1007/s10533-005-1036-2","issn":"01682563","usgsCitation":"Cole, M.L., Kroeger, K.D., McClelland, J., and Valiela, I., 2006, Effects of watershed land use on nitrogen concentrations and δ<sup>15</sup> nitrogen in groundwater: Biogeochemistry, v. 77, no. 2, p. 199-215, https://doi.org/10.1007/s10533-005-1036-2.","productDescription":"17 p.","startPage":"199","endPage":"215","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[],"links":[{"id":477505,"rank":10000,"type":{"id":41,"text":"Open Access External Repository Page"},"url":"https://hdl.handle.net/1912/679","text":"External Repository"},{"id":238923,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":211606,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1007/s10533-005-1036-2"}],"country":"United States","state":"Massachusetts","otherGeospatial":"Cape Cod","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -70.66955566406249,\n              41.51474739095224\n            ],\n            [\n              -70.66955566406249,\n              41.68111756290652\n            ],\n            [\n              -70.4058837890625,\n              41.68111756290652\n            ],\n            [\n              -70.4058837890625,\n              41.51474739095224\n            ],\n            [\n              -70.66955566406249,\n              41.51474739095224\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"77","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a083ce4b0c8380cd51a2c","contributors":{"authors":[{"text":"Cole, Marci L.","contributorId":101071,"corporation":false,"usgs":true,"family":"Cole","given":"Marci","email":"","middleInitial":"L.","affiliations":[],"preferred":false,"id":428640,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Kroeger, Kevin D. 0000-0002-4272-2349 kkroeger@usgs.gov","orcid":"https://orcid.org/0000-0002-4272-2349","contributorId":1603,"corporation":false,"usgs":true,"family":"Kroeger","given":"Kevin","email":"kkroeger@usgs.gov","middleInitial":"D.","affiliations":[{"id":41100,"text":"Coastal and Marine Hazards and Resources Program","active":true,"usgs":true}],"preferred":true,"id":428637,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"McClelland, J.W.","contributorId":62015,"corporation":false,"usgs":true,"family":"McClelland","given":"J.W.","email":"","affiliations":[],"preferred":false,"id":428639,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Valiela, I.","contributorId":29146,"corporation":false,"usgs":true,"family":"Valiela","given":"I.","affiliations":[],"preferred":false,"id":428638,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

At each site, an acoustic Doppler current profiler mounted on a bottom tripod was fitted with an acoustic modem to transmit data to a surface buoy; electronics mounted on the buoy relayed these data to shore via radio modem. The mooring at one site (24 m water depth) was custom-designed for the telemetry application, with a custom designed small buoy, a flexible electro-mechanical buoy to mooring joint using a molded chain connection to the buoy, quick-release electro-mechanical couplings, and dual hydrophones suspended 7 m above the bottom. The surface buoy at the second site (33 m water depth) was a U.S. Coast Guard (USCG) channel buoy fitted with telemetry electronics and clamps to hold the hydrophones. The telemetry was tested in several configurations for a period of about four years. The custom-designed buoy and mooring provided nearly error-free data transmission through the acoustic link under a variety of oceanographic conditions for 261 days at the 24 m site. The electro mechanical joint, cables and couplings required minimal servicing and were very reliable, lasting 862 days deployed before needing repairs. The acoustic communication results from the USCG buoy were poor, apparently due to the hard cobble bottom, noise from the all-steel buoy, and failure of the hydrophone assembly. Access to the USCG buoy at sea required ideal weather. ??2006 IEEE.","largerWorkTitle":"OCEANS 2006","conferenceTitle":"OCEANS 2006","conferenceDate":"18 September 2006 through 21 September 2006","conferenceLocation":"Boston, MA","language":"English","doi":"10.1109/OCEANS.2006.306825","isbn":"1424401151; 9781424401154","usgsCitation":"Martini, M., Butman, B., Ware, J., and Frye, D., 2006, Field tests of acoustic telemetry for a portable coastal observatory, <i>in</i> OCEANS 2006, Boston, MA, 18 September 2006 through 21 September 2006, https://doi.org/10.1109/OCEANS.2006.306825.","costCenters":[],"links":[{"id":204892,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1109/OCEANS.2006.306825"},{"id":218863,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a0fe0e4b0c8380cd53a58","contributors":{"authors":[{"text":"Martini, M.","contributorId":24909,"corporation":false,"usgs":true,"family":"Martini","given":"M.","email":"","affiliations":[],"preferred":false,"id":358669,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Butman, B.","contributorId":85580,"corporation":false,"usgs":true,"family":"Butman","given":"B.","email":"","affiliations":[],"preferred":false,"id":358672,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Ware, J.","contributorId":65984,"corporation":false,"usgs":true,"family":"Ware","given":"J.","email":"","affiliations":[],"preferred":false,"id":358671,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Frye, D.","contributorId":53084,"corporation":false,"usgs":true,"family":"Frye","given":"D.","email":"","affiliations":[],"preferred":false,"id":358670,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

The fresh water endmember of this still relatively pristine estuary may reflect not only river-borne constituents, but also those advected during active groundwater/surface water (hyporheic) exchange. During both discharge conditions, Ba concentrations indicated slight non-conservative mixing. Such Ba excesses could be attributed either to submarine groundwater discharge or particle desorption processes. Estuarine dissolved organic carbon concentrations were highest at salinities closest to zero. Uranium distributions were lowest in the fresh water sites and mixed mostly conservatively with an increase in salinity. Suspended particulate matter (SPM) concentrations were generally lowest (< 5??mg L- 1) close to zero salinity and increased several-fold (??? 18??mg L- 1; low discharge) toward the seaward endmember, which may be attributed to dynamic resuspension of bottom sediments within Jupiter Inlet. Surface water-column 222Rn activities were most elevated (> 28??dpm L- 1) at the freshwater endmember of the estuary and appear to identify regions of the river most influenced by the discharge of fresh groundwater. Activities of four naturally occurring isotopes of Ra (223,224,226,228Ra) in this estuary and select adjacent shallow groundwater wells yield mean estuarine water-mass transit times of less than 1 day; these values are in close agreement to those calculated by tidal prism and tidal frequency. Submarine groundwater discharge rates to the Loxahatchee River estuary were calculated using a tidal prism approach, an excess 226Ra mass balance, and an electromagnetic seepage meter. Average SGD rates ranged from 1.0 to 3.8 ?? 105??m3 d- 1 (20-74??L m- 2 d- 1), depending on river-discharge stage. Such calculated SGD estimates, which must include both a recirculated as well as fresh water component, are in close agreement with results obtained from a first-order watershed mass balance. Average submarine groundwater discharge rates yield NH4+ and PO4- 3 flux estimates to the Loxahatchee River estuary that range from 62.7 to 1063.1 and 69.2 to 378.5????mol m- 2 d- 1, respectively, depending on river stage. SGD-derived nutrient flux rates are compared to yearly computed riverine total N and total P load estimates. ?? 2006 Elsevier B.V.

At the Indiana Geological Survey, the surface area and pore size of the coals will be analyzed using a Micrometrics ASAP 2020, and the CO2 isotherm analyses will be conducted using a volumetric adsorption apparatus in a water temperature bath. The aforementioned analyses will be used to determine site specific correlations for the Kentucky part of the Illinois Basin.

The abrupt eastward drop in relief between these provinces gives rise to unstable conditions and consequent gravitational collapse of large volcanic edifices built at the edge of the Altiplano. Eastward sloping substrate, caused by the irregular configuration of the basement rocks, is the dominant factor that controls the direction of collapsing sectors in all major volcanoes in the region to be preferentially towards the GCP. These collapses produced voluminous debris avalanches and lahars that inundated the well-developed drainages and clastic aprons that characterize the Coastal Plain. Large catastrophic collapses from Citlalte??petl, Las Cumbres, and Cofre de Perote volcanoes are well documented in the geologic record. Some of the avalanches and transformed flows have exceptionally long runouts and reach the Gulf of Mexico traveling more than 120??km from their source. So far, no direct evidence has been found for magmatic activity associated with the initiation of these catastrophic flank-collapses. Apparently, instability of the volcanic edifices has been strongly favored by very intense hydrothermal alteration, abrupt topographic change, and intense fracturing. In addition to the eastward slope of the substrate, the reactivation of pre-volcanic basement structures during the Late Tertiary, and the E-W to ENE-SSW oriented regional stress regimes may have played an important role in the preferential movement direction of the avalanches and flows. In addition to magmatic-hydrothermal processes, high amounts of rainfall in the area is another factor that enhances alteration and eventually weakens the rocks. It is very likely that seismic activity may be the principal triggering mechanism that caused the flank collapse of large volcanic edifices in the Eastern Mexican Volcanic Belt. However, critical pore water pressure from extraordinary amounts of rainfall associated with hurricanes or other meteorological perturbation cannot be ruled out, particularly for smaller volume collapses. There are examples in the area of small seismogenic debris flows that have occurred in historical times, showing that these processes are not uncommon. Assessing the stability conditions of major volcanic edifices that have experienced catastrophic sector collapses is crucial for forecasting future events. This is particularly true for the Eastern Mexican Volcanic Belt, where in many cases no magmatic activity was associated with the collapse. Therefore, edifice failure could occur again without any precursory warning. ?? 2006 Elsevier B.V.

Legal use of AQUI-S&trade; as an anesthetic in U.S. fish culture depends on approval by the U.S. Food and Drug Administration (FDA). To gain approval in the United States, a number of drug attributes must be characterized including (1) depletion of a drug's total residues from edible fillet tissue taken from exposed fish and (2) depletion of one primary drug residue (a marker residue) from the fillet tissue. The marker residue is selected on the basis of data generated during the total residue depletion study. Characterizing marker residue depletion allows the FDA to establish a withdrawal time for exposed fish ensuring total residue concentrations reach safe levels before fish are made available for human consumption in the U.S. Before an AQUI-S&trade; total residue depletion study could be conducted with rainbow trout (<i>Oncorhynchus mykiss</i>), the exposure parameters (water temperature, isoeugenol concentration, and exposure duration) that generate the greatest total AQUI-S&trade; residues in fillet tissue need to be determined.</p>\n<p id=\"\">Rainbow trout were exposed to AQUI-S&trade; in water temperatures of 7, 12, and 17 &deg;C in one of two static exposure regimens: (1) AQUI-S&trade; concentrations of 14 mg/L (nominal concentration) with an exposure duration of 60 min or (2) AQUI-S&trade; concentrations of 34 mg/L (nominal concentration) with an exposure duration of 10 min (exposure conditions based on probable U.S. use regimens).

Ages of multiple corals from localities north of Point An??o Nuevo (central California) and San Nicolas Island (southern California) suggest that this high sea stand could have lasted at least 8000 yr, from ???84,000 to ???76,000 yr BP. These ages overlap with those from marine deposits on tectonically stable Bermuda and tectonically emergent Barbados. Higher-elevation terraces at two California localities, in the Palos Verdes Hills and on San Nicolas Island, have corals with ages that range mostly from ???121,000 to ???116,000 yr BP, correlative with marine isotope substage 5e. These ages are similar to those reported for other terraces in southern California but are younger than some ages reported from Hawaii, Barbados and the Bahamas. Marine terrace faunas are excellent proxies for nearshore marine paleotemperatures during past high sea stands. Terraces on the Palos Verdes Hills and San Nicolas Island dated to the ???120,000 yr BP high sea stand have dominantly zoogeographically \"neutral\" species in exposed coastal localities, indicating nearshore waters similar to those of today. In contrast, ???80,000 yr BP, exposed coastal localities typically have molluscan faunas characterized by numerous extralimital northern species and a lack of extralimital southern species. These fossil assemblages are indicative of nearshore water temperatures that were cooler than modern temperatures at ???80,000 yr BP. Waters at least as warm as today's at ???120,000 yr BP and cooler than present at ???80,000 yr BP are in excellent agreement with marine alkenone records and coastal vegetation records derived from pollen data, from both southern and northern California. Decreased insolation or increased upwelling seem inadequate to explain the cool waters off the Pacific Coast from southern Oregon to southern California at ???80,000 yr BP. We propose that a stronger California Current (or at least one with a greater component of subarctic waters) may explain cooler-than-modern coastal waters during the ???80,000 yr BP high sea stand. ?? 2005 Elsevier Ltd.

Muddy Creek, in south-central Wyoming (Little Snake River watershed), contains sympatric populations of native roundtail chub (Gila robusta), bluehead sucker, (Catostomus discobolus), and flannelmouth sucker (C. tatipinnis), and represents an area of high conservation concern because it is the only area known to have sympatric populations of all 3 species in Wyoming. However, introduced creek chub (Semotilus atromaculatus) are abundant and might have a negative influence on native fishes. We assessed summer food habits of roundtail chub and creek chub to provide information on the ecology of each species and obtain insight on potential trophic overlap. Roundtail chub and creek chub seemed to be opportunistic generalists that consumed a diverse array of food items. Stomach contents of both species were dominated by plant material, aquatic and terrestrial insects, and Fishes, but also included gastropods and mussels. Stomach contents were similar between species, indicating high trophic, overlap. No length-related patterns in diet were observed for either species. These results suggest that creek chubs have the potential to adversely influence the roundtail chub population through competition for food and the native fish assemblage through predation.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Southwestern Naturalist","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1894/0038-4909(2006)51[22:SFHATO]2.0.CO;2","issn":"00384909","usgsCitation":"Quist, M., Bower, M., and Hubert, W., 2006, Summer food habits and trophic overlap of roundtail chub and creek chub in Muddy Creek, Wyoming: Southwestern Naturalist, v. 51, no. 1, p. 22-27, https://doi.org/10.1894/0038-4909(2006)51[22:SFHATO]2.0.CO;2.","startPage":"22","endPage":"27","numberOfPages":"6","costCenters":[],"links":[{"id":211732,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1894/0038-4909(2006)51[22:SFHATO]2.0.CO;2"},{"id":239079,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"51","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505b9f39e4b08c986b31e405","contributors":{"authors":[{"text":"Quist, M.C. 0000-0001-8268-1839","orcid":"https://orcid.org/0000-0001-8268-1839","contributorId":62805,"corporation":false,"usgs":true,"family":"Quist","given":"M.C.","affiliations":[],"preferred":false,"id":428048,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Bower, M.R.","contributorId":14094,"corporation":false,"usgs":true,"family":"Bower","given":"M.R.","email":"","affiliations":[],"preferred":false,"id":428047,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Hubert, W.A.","contributorId":12822,"corporation":false,"usgs":true,"family":"Hubert","given":"W.A.","email":"","affiliations":[],"preferred":false,"id":428046,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

We evaluated the interaction between flow and form by modeling four combinations of modern and historical channel form and modern and historical flow regimes. The analysis used shallow, slow water (shallow-water habitat, SWH, defined as depths between 0 and 1.5 m, and current velocities between 0 and 0.75 m/s) as an indicator of habitat that has been lost on many intensively engineered rivers and one that is thought to be especially important in rearing of young fishes. Two-dimensional hydrodynamic models for modern and historical channels of the Lower Missouri River at Hermann, Missouri, indicate substantial differences between the two channels in total availability and spatial characteristics of SWH. In the modern channel, SWH is maximized at extremely low flows and in overbank flows, whereas the historical channel had substantially more SWH at all discharges and SWH increased with increasing discharge. The historical channel form produced 3-7 times the SWH area of the modern channel regardless of flow regime. The effect of flow regime is evident in increased within-year SWH variability with the natural flow regime, including significant seasonal peaks of SWH associated with spring flooding. Comparison with other reaches along the Lower Missouri River indicates that a) channel form is the dominant control of the availability of habitat even in reaches where the hydrograph is more intensively altered, and b) rehabilitation projects that move toward the historical condition can be successful in increasing topographic diversity and thereby decreasing sensitivity of the availability of habitat to flow regime. The relative efficacy of managing flow and form in creating SWH is useful information toward achieving socially acceptable rehabilitation of the ecosystem in large river systems.</p>","language":"English","publisher":"Elsevier","doi":"10.1016/j.geomorph.2006.01.014","issn":"0169555X","usgsCitation":"Jacobson, R., and Galat, D., 2006, Flow and form in rehabilitation of large-river ecosystems: an example from the Lower Missouri River: Geomorphology, v. 77, no. 3-4, p. 249-269, https://doi.org/10.1016/j.geomorph.2006.01.014.","productDescription":"21 p.","startPage":"249","endPage":"269","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[{"id":192,"text":"Columbia Environmental Research Center","active":true,"usgs":true}],"links":[{"id":236834,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":210036,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.geomorph.2006.01.014"}],"volume":"77","issue":"3-4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a1237e4b0c8380cd5420c","contributors":{"authors":[{"text":"Jacobson, R.

Analysis of well water with four wells from Fallon, Nevada, showed that following recommended procedures for shock chlorinating wells can cause large, short-lasting increases in trace-element concentrations in ground water, particularly for Cu, Fe, Pb, and Zn. Lead concentrations increased up to 745 fold between samples collected just before the well was shock chlorinated and the first sample collected 22-24??h later; Zn concentrations increased up to 252 fold, Fe concentrations increased up to 114 fold, and Cu concentrations increased up to 29 fold. Lead concentrations returned to near background levels following pumping of about one casing volume, however, in one well an estimated 120??mg of excess Pb were pumped before concentrations returned to prechlorination levels. Total Pb concentrations were much greater than filtered (0.45????m) concentrations, indicating the excess Pb is principally particulate. Recommended procedures for purging treated wells following shock chlorination may be ineffective because a strong NaOCl solution can remain in the casing above the pump even following extended pumping. Only small changes in gross alpha and beta radioactivity occurred following shock chlorination. USEPA has not promulgated drinking-water standards for 210Pb, however, measured 210Pb activities in the study area typically were less than the Canadian Maximum Acceptable Concentration of 100??mBq/L. By consuming well water shortly after shock chlorination the public may inadvertently be exposed to levels of Pb, and possibly 210Pb, that exceed drinking-water standards.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Science of the Total Environment","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1016/j.scitotenv.2006.01.020","issn":"00489697","usgsCitation":"Seiler, R.L., 2006, Mobilization of lead and other trace elements following shock chlorination of wells: Science of the Total Environment, v. 367, no. 2-3, p. 757-768, https://doi.org/10.1016/j.scitotenv.2006.01.020.","startPage":"757","endPage":"768","numberOfPages":"12","costCenters":[],"links":[{"id":210375,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.scitotenv.2006.01.020"},{"id":237273,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"367","issue":"2-3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a5b97e4b0c8380cd6f67c","contributors":{"authors":[{"text":"Seiler, R.

As an example, the surficial geologic map of the South Merrimack quadrangle was digitized and several digital geographic information system databases were downloaded from the internet and used to estimate the sand and gravel resources in the quadrangle. More than 41 percent of the South Merrimack quadrangle has been mapped as having sand and (or) gravel deposited by glacial meltwaters. These glaciofluvial areas are estimated to contain a total of 10 million m3 of material mapped as gravel, 60 million m3 of material mapped as mixed sand and gravel, and another 50 million m3 of material mapped as sand with minor silt. The mean thickness of these areas is about 1.95 meters. Twenty tracts were selected, each having individual areas of more than about 14 acres4 (5.67 hectares) of stratified glacial-meltwater sand and gravel deposits, at least 10-feet (3.0 m) of material above the watertable, and not sterilized by the proximity of buildings, roads, streams and other bodies of water, or railroads. The 20 tracts are estimated to contain between about 4 and 10 million short tons (st) of gravel and 20 and 30 million st of sand. The five most gravel-rich tracts contain about 71 to 82 percent of the gravel resources in all 20 tracts and about 54-56 percent of the sand. Using this methodology, and the above criteria, a group of four tracts, divided by narrow areas sterilized by a small stream and secondary roads, may have the highest potential in the quadrangle for sand and gravel resources. ??
