Sand compatibility is fundamental to beach nourishment success and grain size is the parameter often used to evaluate equivalence. Only after understanding which sand sizes naturally compose beaches in a specific cell, especially the smallest size that remains on the beach, can the potential compatibility of source areas, such as offshore borrow sites, be accurately assessed. This study examines sediments on the beach and in the nearshore (5-20m depth) for the entire Santa Barbara Littoral Cell east of Point Conception. A digital bed sediment camera, the Eyeball??, and spatial autocorrelation technique were used to determine sediment grain size. Here we report on whether nearshore sediments are comparable and compatible with beach sands of the Santa Barbara Littoral Cell. ?? 2007 ASCE.","largerWorkTitle":"Coastal Sediments '07 - Proceedings of 6th International Symposium on Coastal Engineering and Science of Coastal Sediment Processes","conferenceTitle":"6th International Symposium on Coastal Engineering and Science of Coastal Sediment Processes","conferenceDate":"13 May 2007 through 17 May 2007","conferenceLocation":"New Orleans, LA","language":"English","doi":"10.1061/40926(239)196","isbn":"0784409269; 9780784409268","usgsCitation":"Mustain, N., Griggs, G., and Barnard, P., 2007, A rapid compatibility analysis of potential offshore sand sources for beaches of the Santa Barbara Littoral Cell, <i>in</i> Coastal Sediments '07 - Proceedings of 6th International Symposium on Coastal Engineering and Science of Coastal Sediment Processes, New Orleans, LA, 13 May 2007 through 17 May 2007, https://doi.org/10.1061/40926(239)196.","costCenters":[],"links":[{"id":212238,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1061/40926(239)196"},{"id":239696,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"noUsgsAuthors":false,"publicationDate":"2012-04-26","publicationStatus":"PW","scienceBaseUri":"5059e52ae4b0c8380cd46b98","contributors":{"authors":[{"text":"Mustain, N.","contributorId":102688,"corporation":false,"usgs":true,"family":"Mustain","given":"N.","affiliations":[],"preferred":false,"id":431847,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Griggs, G.","contributorId":48388,"corporation":false,"usgs":true,"family":"Griggs","given":"G.","affiliations":[],"preferred":false,"id":431846,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Barnard, P.L.","contributorId":20527,"corporation":false,"usgs":true,"family":"Barnard","given":"P.L.","email":"","affiliations":[],"preferred":false,"id":431845,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

In order to better understand the regional trends of change along the California coast, the U.S. Geological Survey is quantifying both sandy shoreline change and coastal cliff retreat for the state. The resulting database was used to examine the dynamics of the beach/cliff system. We found inconsistent evidence of a relationship between rates of cliff retreat and shoreline change on the spatial scale of 100-km cells. However, when the data are correlated within individual regions, a strong relationship exists between the geomorphology of the coast and the behavior of the beach/cliff system. Areas of high-relief coast show negative correlations, indicating that higher rates of cliff retreat correlate with lower rates of shoreline erosion. In contrast, low- to moderate-relief coasts show strong positive correlations.","largerWorkTitle":"Coastal Sediments '07 - Proceedings of 6th International Symposium on Coastal Engineering and Science of Coastal Sediment Processes","conferenceTitle":"6th International Symposium on Coastal Engineering and Science of Coastal Sediment Processes","conferenceDate":"13 May 2007 through 17 May 2007","conferenceLocation":"New Orleans, LA","language":"English","doi":"10.1061/40926(239)133","isbn":"0784409269; 9780784409268","usgsCitation":"Hapke, C., and Reid, D., 2007, Regional beach/cliff system dynamics along the california coast, <i>in</i> Coastal Sediments '07 - Proceedings of 6th International Symposium on Coastal Engineering and Science of Coastal Sediment Processes, New Orleans, LA, 13 May 2007 through 17 May 2007, https://doi.org/10.1061/40926(239)133.","costCenters":[],"links":[{"id":212237,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1061/40926(239)133"},{"id":239695,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"noUsgsAuthors":false,"publicationDate":"2012-04-26","publicationStatus":"PW","scienceBaseUri":"50e4a4aee4b0e8fec6cdbbfc","contributors":{"authors":[{"text":"Hapke, C.J.","contributorId":108233,"corporation":false,"usgs":true,"family":"Hapke","given":"C.J.","email":"","affiliations":[],"preferred":false,"id":431844,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Reid, Don","contributorId":68110,"corporation":false,"usgs":true,"family":"Reid","given":"Don","affiliations":[],"preferred":false,"id":431843,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

The modifications simulated the changes that occur during the tidal cycle in the estuary, scenarios that are not possible with the original EXAMS model. Two models were created within EXAMS, a steady-state model and a time-variant tidally driven model. The steady-state model accounted for tidal flushing by simply altering freshwater input to yield an estuary residence time equal to that measured in Bath Creek. The tidal EXAMS model explicitly incorporated tidal flushing by modifying the EXAMS code to allow for temporal changes in estuary physical attributes (e.g., volume). The models were validated with empirical measurements of atrazine and metolachlor concentrations in the estuary shortly after herbicide application in nearby fields and immediately following a rain event. Both models provided excellent agreement with measured concentrations. The steady-state EXAMS model accurately predicted atrazine concentrations in the middle of the estuary over the first 3 days and under-predicted metolachlor by a factor of 2-3. The time-variant, tidally driven EXAMS model accurately predicted the rise and plateau of both herbicides over the 6-day measurement period. We have demonstrated the ability of these modified EXAMS models to be useful in predicting pesticide fate and exposure in small tidal estuaries. This is a significant improvement and expansion of the application of EXAMS, and given the wide use of EXAMS for surface water quality modeling by both researchers and regulators and the ability of EXAMS to interface with terrestrial models (e.g., pesticide root zone model) and bioaccumulation models, we now have an easily-accessible and widely accepted means of modeling chemical fate in estuaries. ?? 2006 Elsevier B.V.

Four times more landslides were mapped than by previous efforts that used aerial photographs. The mapped landforms (landslides, headscarps, and denuded slopes) were created by many individual landslides. The spatial distribution of mapped landforms and 1308 historical landslides show that historical landslide activity has been concentrated on the mapped landforms, and that most of the landslide activity that created the landforms was prehistoric. Thus, the spatial densities of historical landslides on the landforms provide approximations of the landforms' relative susceptibilities to future landsliding. Historical landslide characteristics appear to be closely related to landform type so relative susceptibilities were determined for landslides with various characteristics. No strong relations were identified between stratigraphy and landslide occurrence; however, landslide characteristics and slope morphology appear to be related to stratigraphic conditions. Human activity is responsible for causing about 80% of historical Seattle landslides. The distribution of mapped landforms and human-caused landslides suggests the probable characteristics of future human-caused landslides on each of the landforms. The distribution of mapped landforms and historical landslides suggests that erosion of slope-toes by surface water has been a necessary condition for causing Seattle landslides. Human activity has largely arrested this erosion, which implies that landslide activity will decrease with time as hillsides naturally stabilize. However, evaluation of glacial-age analogs of areas of recent slope-toe erosion suggests that landslide activity in Seattle will continue for the foreseeable future. ?? 2006 Elsevier B.V.

We use trench mapping and radiometric dating to estimate displacements and timing of the last three surface-rupturing earthquakes (E1-E3) on the southern part of the fault south of Denio, Nevada. Coseismic displacements range from 1.1 to 2.2 ?? 0.5 m, and radiometric ages indicate earthquake times of 11.5 ?? 2.0 ka (E3), 6.1 ?? 0.5 ka (E2), and 4.6 ?? 1.0 ka (E1). These data yield recurrence intervals of 5.4 ?? 2.1 k.y. between E3 and E2, 1.5 ?? 1.1 k.y. between E2 and E1, and an elapsed time of 4.6 ?? 1.0 k.y. since E1. The recurrence data yield variable interval slip rates (between 0.2 ?? 0.22 and 1.5 ?? 2.3 mm/yr), but slip rates averaged over the past ???18 k.y. (0.24 ?? 0.06 mm/year) are similar to long-term (8.5-12.5 Ma) slip rates (0.2 ?? 0.1 mm /yr) measured a few kilometers to the north. We infer from the lack of significant topographic relief across the fault in Bog Hot Valley that the fault zone is propagating southward and may now be connected with a fault at the northwestern end of the Pine Forest Range. Displacements documented in the trench and a rupture length of 37 km indicate a history of three latest Quaternary earthquakes with magnitudes of M 6.6-7.1 on the southern part of the Steens fault zone.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Bulletin of the Seismological Society of America","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1785/0120060202","issn":"00371106","usgsCitation":"Personius, S., Crone, A.J., Machette, M.N., Mahan, S., Kyung, J., Cisneros, H., and Lidke, D., 2007, Late quaternary paleoseismology of the southern Steens fault zone, northern Nevada: Bulletin of the Seismological Society of America, v. 97, no. 5, p. 1662-1678, https://doi.org/10.1785/0120060202.","startPage":"1662","endPage":"1678","numberOfPages":"17","costCenters":[],"links":[{"id":212178,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1785/0120060202"},{"id":239628,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"97","issue":"5","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a4557e4b0c8380cd67229","contributors":{"authors":[{"text":"Personius, S.

These rocks were sampled in situ by ROV and lie beneath a complete upper crustal section providing geological context. This is only the second area (after the Hess Deep) in which a substantial depth into the plutonic complex formed at the East Pacific Rise has been sampled in situ and reveals significant spatial heterogeneity in the plutonic complex. In contrast to the uppermost plutonic rocks at Hess Deep, the rocks studied here are generally primitive with olivine forsterite contents mainly between 85 and 88 and including many troctolites. The melt that the majority of the samples crystallized from was aggregated normal mid-ocean ridge basalt (MORB). Despite this high Mg# clinopyroxene is common despite model predictions that clinopyroxene should not reach the liquidus early during low-pressure crystallization of MORB. Stochastic modeling of melt crystallisation at various levels in the crust suggests that it is unlikely that a significant melt mass crystallized in the deeper crust (for example in sills) because this would lead to more evolved shallow level plutonic rocks. Similar to the upper plutonic section at Hess Deep, and in the Oman ophiolite, many samples show a steeply dipping, axis-parallel, magmatic fabric. This suggests that vertical magmatic flow is an important process in the upper part of the seismic low velocity zone beneath fast-spreading ridges.

Monitoring well networks (16 wells at site A and 6 wells at site C) were established around the lagoons at each facility. Groundwater (n = 124) and lagoon (n = 12) samples were collected from the two sites at six sampling times from 2000 through 2003. Total DNA was extracted, and PCR was used to detect seven Tcr genes [tet(M), tet(O), tet(Q), tet(W), tet(C), tet(H), and tet(Z)]. The concentration of Tcr genes was quantified by real-time quantitative PCR. To confirm the Tcr gene source in groundwater, comparative analysis of tet(W) gene sequences was performed on groundwater and lagoon samples. All seven Tcr genes were continually detected in groundwater during the 3-year monitoring period at both sites. At site A, elevated detection frequency and concentration of Tcr genes were observed in the wells located down-gradient of the lagoon. Comparative analysis of tet(W) sequences revealed that the impacted groundwater contained gene sequences almost identical (99.8% identity) to those in the lagoon, but these genes were not found in background libraries. Novel sequence clusters and unique indigenous resistance gene pools were also found in the groundwater. Thus, antibiotic resistance genes in groundwater are affected by swine manure, but they are also part of the indigenous gene pool. Copyright ?? 2007, American Society for Microbiology.

This suggests that thiadiamondoids and diamondoidthiols form during TSR. In order to prove this hypothesis, we perform laboratory TSR experiments on diverse organic compounds using sodium sulfate as an oxidant in the presence of elemental sulfur and deionized water at 200 and 350 °C for 48 and 96 h under acidic conditions (pH = 4). Our results show that thiadiamondoids and diamondoidthiols can be created from non-sulfur-containing diamondoids by TSR. It seems likely that diamondoid species are organic precursors of thiadiamondoids and diamondoidthiols. In addition, thiocholesterol yields trace quantities of dimethyl-2-thiaadamantanes when heated with montmorillonite at 200 °C, suggesting that these diamondoid derivatives may partly originate by molecular rearrangement of polycyclic sulfides and thiols in the presence of acidic clay minerals since they also exist in crude oil that has not undergone TSR. The present study of these heteroatomic cage compounds improves understanding of TSR and can be used to reduce risk in petroleum exploration.</p></div></div></div></div></div>","language":"English","publisher":"American Chemical Society","doi":"10.1021/ef7003333","issn":"08870624","usgsCitation":"Wei, Z., Moldowan, J., Fago, F., Dahl, J., Cai, C., and Peters, K.E., 2007, Origins of thiadiamondoids and diamondoidthiols in petroleum: Energy and Fuels, v. 21, no. 6, p. 3431-3436, https://doi.org/10.1021/ef7003333.","productDescription":"6 p.","startPage":"3431","endPage":"3436","numberOfPages":"6","costCenters":[],"links":[{"id":240141,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"21","issue":"6","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a711de4b0c8380cd7646e","contributors":{"authors":[{"text":"Wei, Z.","contributorId":12675,"corporation":false,"usgs":true,"family":"Wei","given":"Z.","email":"","affiliations":[],"preferred":false,"id":431805,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Moldowan, J.M.","contributorId":78527,"corporation":false,"usgs":true,"family":"Moldowan","given":"J.M.","email":"","affiliations":[],"preferred":false,"id":431810,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Fago, F.","contributorId":14640,"corporation":false,"usgs":true,"family":"Fago","given":"F.","email":"","affiliations":[],"preferred":false,"id":431806,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Dahl, J.E.","contributorId":14641,"corporation":false,"usgs":true,"family":"Dahl","given":"J.E.","email":"","affiliations":[],"preferred":false,"id":431807,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Cai, C.","contributorId":75757,"corporation":false,"usgs":true,"family":"Cai","given":"C.","email":"","affiliations":[],"preferred":false,"id":431809,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Peters, K.

The ages of dune emplacement range from 0.1 to 103??ka based on radiocarbon (36 samples) and luminescence (46 samples) dating techniques. The majority of the emplacement dates fall into two periods of late-Pleistocene age (11-103??ka) and mid-late-Holocene age (0.1-8??ka) that correspond to marine low-stand and marine high-stand conditions, respectively. The distribution of both the late-Pleistocene dune sheets (516??km2 total surface area) and the late-Holocene dune sheets (184??km2) are concentrated (90% of total surface area) along a 100??km coastal reach of the south-central Oregon coast. This coastal reach lies directly landward of a major bight (Heceta-Perpetua-Stonewall Banks) on the continental shelf, at depths of 30-200??m below present mean sea level (MSL). The banks served to trap northward littoral drift during most of the late-Pleistocene conditions of lowered sea level (- 50 ?? 20??m MSL). The emerged inner-shelf permitted cross-shelf, eolian sand transport (10-50??km distance) by onshore winds. The depocenter sand deposits were reworked by the Holocene marine transgression and carried landward by asymmetric wave transport during early- to mid-Holocene time. The earliest dated onset of Holocene dune accretion occurred at 8??ka in the central Oregon coast. A northward migration of Northeast Pacific storm tracks to the latitude of the shelf depocenter (Stonewall, Perpetua, Heceta Banks) in Holocene time resulted in eastward wave transport from the offshore depocenter. The complex interplay of coastal morphology, paleosea-level, and paleoclimate yielded the observed peak distribution of beach and dune sand observed along the south-central Oregon coast. ?? 2007 Elsevier B.V.

In recent years, the probability of detecting defined population trends has been the most common method of assessing monitoring programs. Such analyses require many assumptions, including a model for population change and a model for variance. To demonstrate potential effects of these assumptions on power analysis results, we present data for Red-tailed Tropicbirds (Phaethon rubricauda) from Tern Island, Hawaii. Depending on our assumptions, the power to detect a 50% decline over 10 years varied from 80% to 100%. We argue that monitoring standards based upon the ability to detect population trends should be applied cautiously. As a complementary approach, we propose that monitoring standards should emphasize attributes of sampling design that increase precision (e.g., randomization, bias, and detection probability). By using standards of precision, managers can focus on the sources of variation that can be minimized. A sampling design approach to monitoring standards provides a useful complement to standards of statistical power to detect annual trends.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Biological Conservation","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1016/j.biocon.2007.08.007","issn":"00063207","usgsCitation":"Seavy, N., and Reynolds, M., 2007, Is statistical power to detect trends a good assessment of population monitoring?: Biological Conservation, v. 140, no. 1-2, p. 187-191, https://doi.org/10.1016/j.biocon.2007.08.007.","startPage":"187","endPage":"191","numberOfPages":"5","costCenters":[],"links":[{"id":212472,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.biocon.2007.08.007"},{"id":239962,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"140","issue":"1-2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a3f2ce4b0c8380cd64306","contributors":{"authors":[{"text":"Seavy, N.E.","contributorId":26403,"corporation":false,"usgs":true,"family":"Seavy","given":"N.E.","affiliations":[],"preferred":false,"id":431747,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Reynolds, M.H. 0000-0001-7253-8158","orcid":"https://orcid.org/0000-0001-7253-8158","contributorId":64214,"corporation":false,"usgs":true,"family":"Reynolds","given":"M.H.","affiliations":[],"preferred":false,"id":431748,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

Twenty-three of the 35 fish and 18 of the 26 macroinvertebrate measures significantly correlated (P < 0.05) with at least one nutrient measure. Percentages of carnivorous, intolerant, and omnivorous fishes, index of biotic integrity, and salmonid abundance were fish measures correlated with the most nutrient measures and had the highest correlation coefficients. Percentages of Ephemeroptera-Plecoptera-Trichoptera individuals and taxa, Hilsenhoff biotic index, and mean tolerance value were macroinvertebrate measures that most strongly correlated with the most nutrient measures. Selected biological measures showed clear trends toward degradation as concentrations of phosphorus and nitrogen increased, and some measures showed clear thresholds where biological measures changed drastically with small changes in nutrient concentrations. Our selected environmental factors explained 54% of the variation in the fish assemblages.

Oil generation curves indicate that peak oil yields occur between 340 and 360 ??C, followed by intense oil cracking in different samples. The biomarker maturity parameters appear to be insensitive to thermal maturation as most of the isomerization ratios of molecular biomarkers in the pyrolysates have reached their equilibrium values. Diamondoids are absent from immature peat extracts, but exist in immature sedimentary rocks in various amounts. This implies that they are not products of biosynthesis and that they may be generated during diagenesis, not just catagenesis and cracking. Most importantly, the concentrations of diamondoids are observed to increase with thermal stress, suggesting that they can be used as a molecular proxy for thermal maturity of source rocks and crude oils. Their abundance is most sensitive to thermal exposure above temperatures of 360-370 ??C (R0 = 1.3-1.5%) for the studied samples, which corresponds to the onset of intense cracking of other less stable components. Below these temperatures, diamondoids increase gradually due to competing processes of generation and dilution. Calibrations were developed between their concentrations and measured vitrinite reflectance through hydrous pyrolysis maturation of different types of rocks and peats. The geochemical models obtained from these methods may provide an alterative approach for determining thermal maturity of source rocks and crude oils, particularly in mature to highly mature Paleozoic carbonates. In addition, the extent of oil cracking was quantified using the concentrations of diamondoids in hydrous pyrolysates of rocks and peats, verifying that these hydrocarbons are valuable indicators of oil cracking in nature. ?? 2006 Elsevier Ltd.

Detrital zircon geochronology in combination with ages on intrusive rocks brackets the deposition of quartzite in the core of the dome sometime between ca. 925 and 620 Ma. Granite and granodiorite intruded the Neoproteorozic metasedimentary rocks in the core of the dome at ca. 620 to 610 Ma. Four major early Permian events associated with the Alleghanian orogeny affected the rocks in the Lyme dome area. Syn-tectonic migmatization and widespread penetrative deformation (D1, ca. 300 - 290 Ma) included emplacement of alaskite at 290 ?? 4 Ma during regional foliation development and aluminosilicate-orthoclase metamorphic conditions. Rocks of the Avalon terrane may have wedged between Gander cover rocks and Gander basement in the core of the Lyme during D1. Limited structural evidence for diapiric uplift of the Lyme dome indicates that diapirism started late in D1 and was completed by D2 (ca. 290 - 280 Ma) when horizontal WNW contractional stresses dominated over vertical stresses. Second sillimanite metamorphism continued and syn-tectonic D2 granite pegmatite (288 ?? 4 Ma) and the Joshua Rock Granite Gniess (284 ?? 3 Ma) intruded at this time. North-northwest extension during D3 (ca. 280 - 275 Ma) led to granitic pegmatite intrusion along S3 cleavage planes and in extensional zones in boudin necks during hydraulic failure and decompression melting. Intrusion of a Westerly Granite dike at 275 ?? 4 Ma suggests that D3 extension was active, and perhaps concluding, by ca. 275 Ma. Late randomly oriented but gently dipping pegmatite dikes record a final stage of intrusion during D4 (ca. 275 - 260 Ma), and a switch from NNW extension to vertical unloading and exhumation. Monazite and metamorphic zircon rim ages record this event at ca. 259 Ma. The evolution of the Lyme dome involved D1 mylonitization, intrusion, and migmatization during north-directed contraction, limited late D1 diapirism, D2 migmatization during WNW contraction with associated flexural flow and fold interference, D3 NNW horizontal extension and decompression melting, and final D4 vertical extension and rapid exhumation. Late regional uplift, extension, and normal faulting at higher crustal levels may have been caused by diapiric rise of the lower crust, below the structural level of the Lyme dome. The rocks record no evidence of Acadian metamorphism or deformation, suggesting that the Gander zone here was not tectonically juxtaposed with Avalon until the Alleghanian orogeny.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"American Journal of Science","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.2475/06.2007.06","issn":"00029599","usgsCitation":"Walsh, G., Aleinikoff, J.N., and Wintsch, R., 2007, Origin of the Lyme Dome and implications for the timing of multiple Alleghanian deformational and intrusive events in southern Connecticut: American Journal of Science, v. 307, no. 1, p. 168-215, https://doi.org/10.2475/06.2007.06.","startPage":"168","endPage":"215","numberOfPages":"48","costCenters":[],"links":[{"id":213276,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.2475/06.2007.06"},{"id":240886,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"307","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a70fbe4b0c8380cd763a1","contributors":{"authors":[{"text":"Walsh, G.

The hemagglutinin (HA) and neuraminidase (NA) genes from all 6 H5N1 viruses and an additional 38 North American wild-bird-origin H5 subtype and 28 N1 subtype viruses were sequenced and compared with sequences available in GenBank by phylogenetic analysis. Both HA and NA were phylogenetically distinct from those for viruses from outside of North America and from those for viruses recovered from mammals. Four of the H5N1 AI viruses were characterized as low pathogenicity by standard in vivo pathotyping tests. One of the H5N1 viruses, A/MuteSwan/MI/451072-2/06, was shown to replicate to low titers in chickens, turkeys, and ducks. However, transmission of A/MuteSwan/MI/451072-2/06 was more efficient among ducks than among chickens or turkeys based on virus shed. The 50% chicken infectious dose for A/MuteSwan/MI/451072-2/06 and three other wild-waterfowl-origin H5 viruses were also determined and were between 10 5.3 and 107.5 50% egg infective doses. Finally, seven H5 viruses representing different phylogenetic clades were evaluated for their antigenic relatedness by hemagglutination inhibition assay, showing that the antigenic relatedness was largely associated with geographic origin. Overall, the data support the conclusion that North American H5 wild-bird-origin AI viruses are low-pathogenicity wild-bird-adapted viruses and are antigenically and genetically distinct from the highly pathogenic Asian H5N1 virus lineage.

Consequently, chronic exposure to elevated noise levels in tanks could negatively impact cultured species. Possible effects include impairment of the auditory system, increased stress, and reduced growth rates. The objective of this study was to evaluate the long-term effects of sound exposure on the hearing sensitivity, growth, and survival of cultured rainbow trout (Oncorhynchus mykiss). Two cohorts of rainbow trout were cultured for 8??months in replicated tanks consisting of three sound treatments: 115, 130, or 150 decibels referenced at 1 micropascal (dB re 1????Pa root mean square [RMS]) levels. Auditory evoked potential (AEP) recordings revealed no significant differences in hearing thresholds resulting from exposure to increased ambient sound levels. Although there was no evident noise-induced hearing loss, there were significant differences in hearing thresholds between the two fish cohorts examined. No statistical effect of sound treatment was found for growth rate and mortality within each fish cohort. There was no significant difference in mortality between sound treatments when fish were exposed to the pathogen Yersinia ruckeri, but there was significantly different mortality between cohorts. This study indicated that rainbow trout hearing sensitivity, growth, survival, stress, and disease susceptibility were not negatively impacted by noise levels common to recirculating aquaculture systems. These findings should not be generalized to all cultured fish species, however, because many species, including catfish and cyprinids, have much greater hearing sensitivity than rainbow trout and could be affected differently by noise. ?? 2007 Elsevier B.V.

A map of the State was prepared that shows the average annual base flow for the period 1970-99 for watersheds at 118 gaging stations. Trend analysis was performed on 22 of the 118 streamflow-gaging stations that had long-term records, unregulated flow, and provided aerial coverage of the State. The analysis found that a statistically significant increasing trend was occurring for watersheds where the primary land use was agriculture. Most gaging stations where the land cover was forest had no significant trend. A method to estimate the average annual base flow at ungaged sites was developed by multiple-regression analysis using basin characteristics. The equation with the lowest standard error of estimate, 9.5%, has drainage area, soil infiltration and base flow factor as independent variables. To determine the average annual base flow for smaller watersheds, estimates were made at low-flow partial-record stations in 3 of the 12 major river basins in Wisconsin. Regression equations were developed for each of the three major river basins using basin characteristics. Drainage area, soil infiltration, basin storage and base-flow factor were the independent variables in the regression equations with the lowest standard error of estimate. The standard error of estimate ranged from 17% to 52% for the three river basins. ?? 2007 American Water Resources Association.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of the American Water Resources Association","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1111/j.1752-1688.2007.00018.x","issn":"1093474X","usgsCitation":"Gebert, W., Radloff, M., Considine, E., and Kennedy, J., 2007, Use of streamflow data to estimate base flowground-water recharge for Wisconsin: Journal of the American Water Resources Association, v. 43, no. 1, p. 220-236, https://doi.org/10.1111/j.1752-1688.2007.00018.x.","startPage":"220","endPage":"236","numberOfPages":"17","costCenters":[],"links":[{"id":213301,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1111/j.1752-1688.2007.00018.x"},{"id":240913,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"43","issue":"1","noUsgsAuthors":false,"publicationDate":"2007-02-12","publicationStatus":"PW","scienceBaseUri":"505bbf8ce4b08c986b329c10","contributors":{"authors":[{"text":"Gebert, W.A.","contributorId":71555,"corporation":false,"usgs":true,"family":"Gebert","given":"W.A.","email":"","affiliations":[],"preferred":false,"id":439206,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Radloff, M.J.","contributorId":33929,"corporation":false,"usgs":true,"family":"Radloff","given":"M.J.","email":"","affiliations":[],"preferred":false,"id":439205,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Considine, E.J.","contributorId":10229,"corporation":false,"usgs":true,"family":"Considine","given":"E.J.","email":"","affiliations":[],"preferred":false,"id":439204,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Kennedy, J.L.","contributorId":98120,"corporation":false,"usgs":true,"family":"Kennedy","given":"J.L.","email":"","affiliations":[],"preferred":false,"id":439207,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

New magnetic dipoles, which vary with stress changes from mechanical sources, are produced on the walls of the borehole. We evaluate such an effect quantitatively. First we formulate a general expression for the borehole effect due to any arbitrary source models. This is valid everywhere above the ground surface as well as within the cylindrical hole. A first-order approximate solution is given by a line of horizontal dipoles and vertical quadrupoles along the central axis of the borehole, which is valid above the ground surface and a slightly away (several tens of cm) from the top of the borehole. Selecting the Mogi model as an example, we numerically evaluated the borehole effect. It turned out that the vertical quadrupoles produce two orders of magnitude more intense magnetic field than the horizontal dipoles. The borehole effect is very local, i.e. detectable only within a few m from its outlet, since it is of the same order or more than the case without a borehole. However, magnetic lines of force cannot reach the ground surface from a deeper portion (> 10 m) of a borehole.","language":"English","publisher":"INGV","doi":"10.4401/ag-3089","issn":"15935213","usgsCitation":"Sasai, Y., Johnston, M., Tanaka, Y., Mueller, R., Hashimoto, T., Utsugi, M., Sakanaka, S., Uyeshima, M., Zlotnicki, J., and Yvetot, P., 2007, Drag-out effect of piezomagnetic signals due to a borehole: The Mogi source as an example: Annals of Geophysics, v. 50, no. 1, p. 93-104, https://doi.org/10.4401/ag-3089.","productDescription":"12 p.","startPage":"93","endPage":"104","numberOfPages":"12","costCenters":[{"id":615,"text":"Volcano Hazards Program","active":true,"usgs":true}],"links":[{"id":477103,"rank":1,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.4401/ag-3089","text":"Publisher Index Page"},{"id":240884,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"50","issue":"1","noUsgsAuthors":false,"publicationDate":"2009-12-18","publicationStatus":"PW","scienceBaseUri":"505a03bee4b0c8380cd50630","contributors":{"authors":[{"text":"Sasai, Y.","contributorId":50340,"corporation":false,"usgs":true,"family":"Sasai","given":"Y.","affiliations":[],"preferred":false,"id":439200,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Johnston, M.J.S. 0000-0003-4326-8368","orcid":"https://orcid.org/0000-0003-4326-8368","contributorId":104889,"corporation":false,"usgs":true,"family":"Johnston","given":"M.J.S.","affiliations":[],"preferred":false,"id":439203,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Tanaka, Y.","contributorId":14214,"corporation":false,"usgs":true,"family":"Tanaka","given":"Y.","email":"","affiliations":[],"preferred":false,"id":439196,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Mueller, R.","contributorId":23398,"corporation":false,"usgs":true,"family":"Mueller","given":"R.","email":"","affiliations":[],"preferred":false,"id":439197,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Hashimoto, T.","contributorId":9535,"corporation":false,"usgs":true,"family":"Hashimoto","given":"T.","email":"","affiliations":[],"preferred":false,"id":439195,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Utsugi, M.","contributorId":45586,"corporation":false,"usgs":true,"family":"Utsugi","given":"M.","email":"","affiliations":[],"preferred":false,"id":439199,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Sakanaka, S.","contributorId":55697,"corporation":false,"usgs":true,"family":"Sakanaka","given":"S.","email":"","affiliations":[],"preferred":false,"id":439202,"contributorType":{"id":1,"text":"Authors"},"rank":7},{"text":"Uyeshima, M.","contributorId":55293,"corporation":false,"usgs":true,"family":"Uyeshima","given":"M.","email":"","affiliations":[],"preferred":false,"id":439201,"contributorType":{"id":1,"text":"Authors"},"rank":8},{"text":"Zlotnicki, J.","contributorId":43636,"corporation":false,"usgs":true,"family":"Zlotnicki","given":"J.","email":"","affiliations":[],"preferred":false,"id":439198,"contributorType":{"id":1,"text":"Authors"},"rank":9},{"text":"Yvetot, P.","contributorId":9136,"corporation":false,"usgs":true,"family":"Yvetot","given":"P.","email":"","affiliations":[],"preferred":false,"id":439194,"contributorType":{"id":1,"text":"Authors"},"rank":10}]}}

As management has shifted, relevant environmental characteristics have evolved from traditional metrics that described local habitat quality to characterizations of habitat size and connectivity. Despite the implications this shift has for how habitats may be prioritized for conservation, it has been rare to assess the relative importance of these habitat components. We used an information-theoretic approach to select the best models from sets of logistic regressions that linked habitat quality, size, and connectivity to the occurrence of chinook salmon (Oncorhynchus tshawytscha) nests. Spawning distributions were censused annually from 1995 to 2004, and data were complemented with field measurements that described habitat quality in 43 suitable spawning patches across a stream network that drained 1150 km 2 in central Idaho. Results indicated that the most plausible models were dominated by measures of habitat size and connectivity, whereas habitat quality was of minor importance. Connectivity was the strongest predictor of nest occurrence, but connectivity interacted with habitat size, which became relatively more important when populations were reduced. Comparison of observed nest distributions to null model predictions confirmed that the habitat size association was driven by a biological mechanism when populations were small, but this association may have been an area-related sampling artifact at higher abundances. The implications for habitat management are that the size and connectivity of existing habitat networks should be maintained whenever possible. In situations where habitat restoration is occurring, expansion of existing areas or creation of new habitats in key areas that increase connectivity may be beneficial. Information about habitat size and connectivity also could be used to strategically prioritize areas for improvement of local habitat quality, with areas not meeting minimum thresholds being deemed inappropriate for pursuit of restoration activities. ?? 2007 by the Ecological Society of America.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Ecological Applications","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1890/05-1949","issn":"10510761","usgsCitation":"Isaak, D., Thurow, R., Rieman, B., and Dunham, J., 2007, Chinook salmon use of spawning patches: Relative roles of habitat quality, size, and connectivity: Ecological Applications, v. 17, no. 2, p. 352-364, https://doi.org/10.1890/05-1949.","startPage":"352","endPage":"364","numberOfPages":"13","costCenters":[{"id":290,"text":"Forest and Rangeland Ecosystem Science Center","active":false,"usgs":true}],"links":[{"id":240883,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":213274,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1890/05-1949"}],"volume":"17","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059f5bce4b0c8380cd4c3bb","contributors":{"authors":[{"text":"Isaak, D.J.","contributorId":77326,"corporation":false,"usgs":true,"family":"Isaak","given":"D.J.","email":"","affiliations":[],"preferred":false,"id":439192,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Thurow, R.F.","contributorId":69357,"corporation":false,"usgs":true,"family":"Thurow","given":"R.F.","email":"","affiliations":[],"preferred":false,"id":439191,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Rieman, B.E.","contributorId":67283,"corporation":false,"usgs":true,"family":"Rieman","given":"B.E.","email":"","affiliations":[],"preferred":false,"id":439190,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Dunham, J.

A multisite investigation assessed the major controls on these fluctuations and the ecohydrologic insights that can be gleaned from them. Spatial and temporal variations in the amplitude of the fluctuations are primarily a function of variations in (1) the meteorological drivers of plant water use, (2) vegetation density, type, and vitality, and (3) the specific yield of sediments in the vicinity of the water table. Past hydrologic conditions experienced by the riparian zone vegetation, either in previous years or earlier within the same growing season, are also an important control. Diurnal water table fluctuations can be considered a diagnostic indicator of groundwater consumption by phreatophytes at most sites, so the information embedded within these fluctuations should be more widely exploited in ecohydrologic studies.</span></p>","language":"English","publisher":"American Geophysical Union","doi":"10.1029/2005WR004627","usgsCitation":"Butler, J.J., Kluitenberg, G.J., Whittemore, D.O., Loheide, S.P., Jin, W., Billinger, M.A., and Zhan, X., 2007, A field investigation of phreatophyte‐induced fluctuations in the water table: Water Resources Research, v. 43, no. 2, Article W02404; 12 p., https://doi.org/10.1029/2005WR004627.","productDescription":"Article W02404; 12 p.","costCenters":[],"links":[{"id":477034,"rank":1,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1029/2005wr004627","text":"Publisher Index Page"},{"id":240712,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"43","issue":"2","noUsgsAuthors":false,"publicationDate":"2007-02-07","publicationStatus":"PW","scienceBaseUri":"5059e3d3e4b0c8380cd46241","contributors":{"authors":[{"text":"Butler, James J.
