Comparison of groundwaters with modern precipitation","docAbstract":"Groundwater samples from wells and springs, scattered over most of the Great Basin province, were collected and analyzed for their isotopic makeup. They were augmented by previously published isotopic data on groundwaters from southeast California and by several hundred unpublished isotopic analyses. The ratio of 2H (deuterium, D) to 1H, in water samples from valleys in parts of California, Idaho, Nevada, Oregon, and Utah, are here compared with the winter, summer, and annual isotopic compositions of precipitation falling in or near the sampled areas. The main goal of this study was to identify basins where the groundwaters have isotopic compositions that are \"lighter\" (depleted in the heavier isotope, D) relative to modern winter precipitation. Where these basins do not adjoin substantially higher terrain, we consider those light groundwaters to be of Pleistocene age and thus more than 10,000 years old. Where the groundwater is 10 to 19??? lighter than local winter precipitation, we consider it to be possibly an indication of Pleistocene water; where the ??D makeup is >20??? lighter, we consider it to be probably Pleistocene water. More than 80 sites underlain by waters of possible or probable Pleistocene age were identified.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Geophysical Research D: Atmospheres","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1029/2001JD000567","issn":"01480227","usgsCitation":"Smith, G., Friedman, I., Veronda, G., and Johnson, C.A., 2002, Stable isotope compositions of waters in the Great Basin, United States 3.

An&nbsp;</span><sup>40</sup><span>Ar/</span><sup>39</sup><span>Ar age of 174 Ma and the chemical character of the basaltic rocks show the BRIC to be part of the widespread Jurassic Ferrar suite of continental tholeiitic rocks, that extends for 3500 km across Antarctica. The aeromagnetic survey shows a horseshoe-shaped pattern of anomalies reaching amplitudes as great as 1900 nT generally associated with the bedrock topography where it is exposed. It is apparent that the high-amplitude anomaly pattern is more extensive than the 10-km-long exposed outcrop, first crossed by a single 1990 aeromagnetic profile. The highest-amplitude anomalies appear south of the profile acquired in 1990 and extend out of the survey area. The new aeromagnetic data allow determination of the extent of the interpreted Butcher mafic(?) intrusion beneath exposures of Beacon sedimentary rock and ice in the area covered, as well as beneath the small BRIC exposure.

Magnetic models indicate a minimum thickness of ∼1–2 km for a horizontal intrusion. However, nonunique models with magnetic layers decreasing in apparent susceptibility with depth are consistent with of a 4- to 8-km-thick layered intrusion. These magnetic models indicate progressively deeper erosion of the interpreted mafic-layered body from the south to north. The erosion has removed more magnetic upper layers that mask the magnetic effects of the lower less magnetic layers.

Physically plausible bounds on groundwater flow and an effective transport-resistance parameter are estimated based on fundamental principles and idealised models of pore geometry. Application to an intensively characterised site in Sweden shows that, due to high spatial variability and uncertainty regarding properties of transport paths, the uncertainty associated with the geological barrier is too high to allow meaningful discrimination between good and poor performance. Application of more complex (stochastic-continuum and discrete-fracture-network) models does not yield a significant improvement in the resolution of geologic-barrier performance. Comparison with seven other less intensively characterised crystalline study sites in Sweden leads to similar results, raising a question as to what extent the geological barrier function can be characterised by state-of-the art site investigation methods prior to repository construction. A simple evaluation provides a simple and robust practical approach for inclusion in performance assessment.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Acta Universitatis Carolinae, Geologica","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"Czech","issn":"00017132","usgsCitation":"Geier, J., Voss, C., and Dverstorp, B., 2002, Conceptual uncertainty in crystalline bedrock: Is simple evaluation the only practical approach?: Acta Universitatis Carolinae, Geologica, v. 46, no. 2-3, p. 544-548.","startPage":"544","endPage":"548","numberOfPages":"5","costCenters":[],"links":[{"id":231793,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"46","issue":"2-3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059f9abe4b0c8380cd4d706","contributors":{"authors":[{"text":"Geier, J.","contributorId":33488,"corporation":false,"usgs":true,"family":"Geier","given":"J.","email":"","affiliations":[],"preferred":false,"id":399830,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Voss, C.I.","contributorId":79515,"corporation":false,"usgs":true,"family":"Voss","given":"C.I.","email":"","affiliations":[],"preferred":false,"id":399831,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Dverstorp, B.","contributorId":82490,"corporation":false,"usgs":true,"family":"Dverstorp","given":"B.","email":"","affiliations":[],"preferred":false,"id":399832,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

The Rialto-Colton aquifer has been divided into four primary and significant flowpaths following the general direction of groundwater flow from NW to SE. The introductory investigation include sophisticated chemical reaction modeling, with highly simplified flow path simulation. A comprehensive reactive transport model with the established set of geochemical reactions over the whole aquifer will also be developed for treating both reactions and transport realistically. This will be completed by making use of HBGC123D implemented with isotopic calculation step to compute Carbon-14 (C14) and stable Carbon-13 (C13) contents of the water. Computed carbon contents will also be calibrated with the measured carbon contents for assessment of the amount of imported recharge into the Linden pond.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Report - University of California Water Resources Center","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","issn":"05754968","usgsCitation":"Ginn, T., and Woolfenden, L., 2002, Application of a new model for groundwater age distributions: Modeling and isotopic analysis of artificial recharge in the Rialto-Colton basin, California: Report - University of California Water Resources Center, no. 103, p. 15-17.","startPage":"15","endPage":"17","numberOfPages":"3","costCenters":[],"links":[{"id":232062,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"issue":"103","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059ec8fe4b0c8380cd49344","contributors":{"authors":[{"text":"Ginn, T.R.","contributorId":58052,"corporation":false,"usgs":true,"family":"Ginn","given":"T.R.","email":"","affiliations":[],"preferred":false,"id":399915,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Woolfenden, L. 0000-0003-3500-4709","orcid":"https://orcid.org/0000-0003-3500-4709","contributorId":92015,"corporation":false,"usgs":true,"family":"Woolfenden","given":"L.","affiliations":[],"preferred":false,"id":399916,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

The original IBI, developed for streams in the U.S. Midwest, was modified to reflect the assemblage composition and structure present in Mid-Atlantic Slope drainages. We replaced several of the Midwestern IBI metrics and criteria scores because fishes common to the Midwest are absent from or poorly represented in the Northeast and because stream fish assemblages in the Northeast are less rich than those in the Midwest. For all replacement metrics we followed the ecology-based rationale used in the development of each of the metrics of the Midwestern IBI so that the basic theoretical underpinnings of the IBI remained unchanged. The validity of this modified IBI is demonstrated by examining the quality of streams in the Hudson, Delaware, and lower Susquehanna River basins. The relationships between the IBI and other indicators of environmental quality are examined using data on assemblages of fish and benthic macroinvertebrates and on chemical and physical stream characteristics obtained during 1993-2000 by the U.S. Geological Survey's National Water Quality Assessment Program in these three river basins. A principal components analysis (PCA) of chemical and physical variables from 27 sites resulted in an environmental quality gradient as the primary PCA axis (eigenvalue, 0.41 ). Principal components analysis site scores were significantly correlated with such benthic macroinvertebrate metrics as the percentage of Ephemeroptera, Plecoptera, and Trichoptera taxa (Spearman R = -0.66, P < 0.001). Index of biological integrity scores for sites in these three river basins were significantly correlated with this environmental quality gradient (Spearman R = -0.78, P = 0.0001). The northern Mid-Atlantic Slope IBI appears to be sensitive to environmental degradation in all three of the river basins addressed in this study. Adjustment of metric scoring criteria may be warranted, depending on composition of fish species in streams in the study area and on the relative effort used in the collection of fish assemblage data.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Transactions of the American Fisheries Society","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1577/1548-8659(2002)131<1044:AIOBIF>2.0.CO;2","issn":"00028487","usgsCitation":"Daniels, R., Riva-Murray, K., Halliwell, D., Vana-Miller, D.L., and Bilger, M.D., 2002, An index of biological integrity for northern Mid-Atlantic Slope drainages: Transactions of the American Fisheries Society, v. 131, no. 6, p. 1044-1060, https://doi.org/10.1577/1548-8659(2002)131<1044:AIOBIF>2.0.CO;2.","startPage":"1044","endPage":"1060","numberOfPages":"17","costCenters":[],"links":[{"id":207042,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1577/1548-8659(2002)131<1044:AIOBIF>2.0.CO;2"},{"id":231601,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"131","issue":"6","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059ea77e4b0c8380cd4889f","contributors":{"authors":[{"text":"Daniels, R.A.","contributorId":34290,"corporation":false,"usgs":true,"family":"Daniels","given":"R.A.","email":"","affiliations":[],"preferred":false,"id":399956,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Riva-Murray, K.","contributorId":82481,"corporation":false,"usgs":true,"family":"Riva-Murray","given":"K.","affiliations":[],"preferred":false,"id":399958,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Halliwell, D.B.","contributorId":90904,"corporation":false,"usgs":true,"family":"Halliwell","given":"D.B.","email":"","affiliations":[],"preferred":false,"id":399959,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Vana-Miller, D.

Phase relations at H<sub>2</sub>O+CO<sub>2</sub> fluid saturation were determined for an andesite (58.7 wt% SiO<sub>2</sub>) and a dacite (67.7 wt%) from the compositional extremes of intermediate magmas erupted. The phase assemblages, matrix melt composition and modes of natural andesite were reproduced experimentally under H<sub>2</sub>O-saturated conditions (i.e., P<sub>H2O</sub>=P<sub>TOT</sub>) in a negatively sloping region in T-P space from 930 <strong>°</strong>C/100 MPa to 960 <strong>°</strong>C/75 MPa with <i>f</i>O<sub>2</sub>~N NO + 1. The H<sub>2</sub>O-saturated equilibration conditions of the dacite are constrained to a T-P region from 850 <strong>°</strong>C/ 50 MPa to 880 <strong>°</strong>C/25 MPa. If H<sub>2</sub>O-saturated, these magmas equilibrated at (and above) the level where coerupted rhyolite equilibrated (~100 MPa), suggesting that the andesite-dacite magma reservoir was displaced laterally rather than vertically from the rhyolite magma body. Natural mineral and melt compositions of intermediate magmas were also reproduced experimentally under saturation conditions with a mixed (H<sub>2</sub>O + CO<sub>2</sub>) fluid for the same range in P<sub>H2O</sub>. Thus, a storage model in which vertically stratified mafic to silicic intermediate magmas underlay H<sub>2</sub>O-saturated rhyolite is consistent with experimental findings only if the intermediates have X<sub>H2O</sub>fl=0.7 and 0.9 for the extreme compositions, respectively. Disequilibrium features in natural pumice and scoria include pristine minerals existing outside their stability fields, and compositional zoning of titanomagnetite in contact with ilmenite. Variable rates of chemical equilibration which would eliminate these features constrain the apparent thermal excursion and re-distribution of minerals to the time scale of days.</p>","language":"English","doi":"10.1007/s00410-002-0393-2","usgsCitation":"Hammer, J., Rutherford, M., and Hildreth, W., 2002, Magma storage prior to the 1912 eruption at Novarupta, Alaska: Contributions to Mineralogy and Petrology, v. 144, no. 2, p. 144-162, https://doi.org/10.1007/s00410-002-0393-2.","productDescription":"19 p.","startPage":"144","endPage":"162","costCenters":[{"id":617,"text":"Volcano Science Center","active":true,"usgs":true}],"links":[{"id":231872,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Alaska","otherGeospatial":"Novarupta","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -155.3466796875,\n              58.14896803443219\n            ],\n            [\n              -154.95117187499997,\n              58.14896803443219\n            ],\n            [\n              -154.95117187499997,\n              58.238717823301876\n            ],\n            [\n              -155.3466796875,\n              58.238717823301876\n            ],\n            [\n              -155.3466796875,\n              58.14896803443219\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"144","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a4b3ce4b0c8380cd693ae","contributors":{"authors":[{"text":"Hammer, J.E.","contributorId":8246,"corporation":false,"usgs":true,"family":"Hammer","given":"J.E.","email":"","affiliations":[],"preferred":false,"id":400018,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Rutherford, M.J.","contributorId":103039,"corporation":false,"usgs":true,"family":"Rutherford","given":"M.J.","email":"","affiliations":[],"preferred":false,"id":400020,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"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":400019,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

These include, but are not limited to, cratonization, terrane accretion and collision, continental rifting (both passive and active), subduction, and lithospheric basal erosion due to a relative motion of cratonic keels and the convective mantle.&nbsp;</p>","largerWorkTitle":"","language":"English","publisher":"Elsevier","doi":"10.1016/S0040-1951(02)00530-9","issn":"00401951","usgsCitation":"Artemieva, I., Mooney, W.D., Perchuc, E., and Thybo, H., 2002, Processes of lithosphere evolution: New evidence on the structure of the continental crust and uppermost mantle: Tectonophysics, v. 358, no. 1-4, p. 1-15, https://doi.org/10.1016/S0040-1951(02)00530-9.","productDescription":"15 p.","startPage":"1","endPage":"15","numberOfPages":"15","costCenters":[{"id":237,"text":"Earthquake Science Center","active":true,"usgs":true}],"links":[{"id":478759,"rank":1,"type":{"id":41,"text":"Open Access External Repository Page"},"url":"https://curis.ku.dk/ws/files/49250825/2002_Tectp_Intro_Art_etal.pdf","text":"External Repository"},{"id":232028,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"358","issue":"1-4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a8db9e4b0c8380cd7edba","contributors":{"authors":[{"text":"Artemieva, I.M.","contributorId":71728,"corporation":false,"usgs":true,"family":"Artemieva","given":"I.M.","email":"","affiliations":[],"preferred":false,"id":400182,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Mooney, Walter D. 0000-0002-5310-3631 mooney@usgs.gov","orcid":"https://orcid.org/0000-0002-5310-3631","contributorId":3194,"corporation":false,"usgs":true,"family":"Mooney","given":"Walter","email":"mooney@usgs.gov","middleInitial":"D.","affiliations":[{"id":237,"text":"Earthquake Science Center","active":true,"usgs":true}],"preferred":true,"id":400183,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Perchuc, E.","contributorId":41185,"corporation":false,"usgs":true,"family":"Perchuc","given":"E.","email":"","affiliations":[],"preferred":false,"id":400180,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Thybo, H.","contributorId":57599,"corporation":false,"usgs":true,"family":"Thybo","given":"H.","affiliations":[],"preferred":false,"id":400181,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

We discuss the origin of such large differences in lithospheric thickness, and propose that the lithospheric base can have large depth variations over short distances. The topography of Bryce Canyon (western USA) is proposed as an inverted analog of the base of the lithosphere. The horizontal and vertical dimensions of Archean cratons are strongly correlated: larger cratons have thicker lithosphere. Analysis of the bimodal distribution of lithospheric thickness in Archean cratons shows that the \"critical\" surface area for cratons to have thick (&gt;300 km) keels is &gt;6-8 ?? 106 km2 . Extrapolation of the linear trend between Archean lithospheric thickness and cratonic area to zero area yields a thickness of 180 km. This implies that the reworking of Archean crust should be accompanied by thinning and reworking of the entire lithospheric column to a thickness of 180 km in accord with thickness estimates for Proterozoic lithosphere. Likewise, extrapolation of the same trend to the size equal to the total area of all Archean cratons implies that the lithospheric thickness of a hypothesized early Archean supercontinent could have been 350-450 km decreasing to 280-400 km for Gondwanaland. We evaluate the basal drag model as a possible mechanism that may thin the cratonic lithosphere. Inverse correlations are found between lithospheric thickness and (a) fractional subduction length and (b) the effective ridge length. In agreement with theoretical predictions, lithospheric thickness of Archean keels is proportional to the square root of the ratio of the craton length (along the direction of plate motion) to the plate velocity. Large cratons with thick keels and low plate velocities are less eroded by basal drag than small fast-moving cratons. Basal drag may have varied in magnitude over the past 4 Ga. Higher mantle temperatures in the Archean would have resulted in lower mantle viscosity. This in turn would have reduced basal drag and basal erosion, and promoted the preservation of thick (&gt;300 km) Archean keels, even if plate velocities were high during the Archean.</p>","largerWorkTitle":"","language":"English","publisher":"Elsevier","doi":"10.1016/S0040-1951(02)00425-0","issn":"00401951","usgsCitation":"Artemieva, I., and Mooney, W.D., 2002, On the relations between cratonic lithosphere thickness, plate motions, and basal drag: Tectonophysics, v. 358, no. 1-4, p. 211-231, https://doi.org/10.1016/S0040-1951(02)00425-0.","productDescription":"21 p.","startPage":"211","endPage":"231","numberOfPages":"21","costCenters":[{"id":237,"text":"Earthquake Science Center","active":true,"usgs":true}],"links":[{"id":232067,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"358","issue":"1-4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a6dede4b0c8380cd753df","contributors":{"authors":[{"text":"Artemieva, I.M.","contributorId":71728,"corporation":false,"usgs":true,"family":"Artemieva","given":"I.M.","email":"","affiliations":[],"preferred":false,"id":400184,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Mooney, Walter D. 0000-0002-5310-3631 mooney@usgs.gov","orcid":"https://orcid.org/0000-0002-5310-3631","contributorId":3194,"corporation":false,"usgs":true,"family":"Mooney","given":"Walter","email":"mooney@usgs.gov","middleInitial":"D.","affiliations":[{"id":237,"text":"Earthquake Science Center","active":true,"usgs":true}],"preferred":true,"id":400185,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

The variables, water-surface width and average depth, were measured at 58 to 888 equally spaced cross-sections in channel links (river reaches between major tributaries). These measurements provide data to characterize the two-dimensional structure of a channel link which is the fundamental unit of a channel network. The morphological variables have nearly log-normal probability distributions. A general relation was determined which relates the means of the log-transformed variables to the logarithm of discharge similar to previously published downstream hydraulic geometry relations. The spatial variability of the variables is described by two properties: (1) the coefficient of variation which was nearly constant (0.13-0.42) over a wide range of discharge; and (2) the integral length scale in the downstream direction which was approximately equal to one to two mean channel widths. The joint probability distribution of the morphological variables in the downstream direction was modelled as a first-order, bivariate autoregressive process. This model accounted for up to 76 per cent of the total variance. The two-dimensional morphological variables can be scaled such that the channel width-depth process is independent of discharge. The scaling properties will be valuable to modellers of both basin and channel dynamics.

Here I describe five elements of integration in management: taxonomic, spatial, temporal, population and habitat, and multiple-use management objectives. Spatial integration simply expands the scale of management concern. Rather than emphasizing management on a very limited number of impoundments or wetlands in small refuges or wildlife management areas, the vision is beginning to shift to connectivity within larger landscapes on the order of many square kilometers as telemetry data on daily and seasonal movements for many species become available. Temporal integration refers to the potential for either simultaneous management for waterbirds and commercial \"crops\" (e.g., crayfish and rice) or for temporally-staggered management such as row crop production in spring-summer growing seasons and waterbird management on fallow fields in the non-growing (winter) season. Integrating population dynamics with habitats has become a major research focus over the past decade. Identifying which wetlands are \"sources\" or \"sinks\" for specific populations provides managers with critical information about effective management. Further, the applications of spatially explicit population models place heavy demands on researchers to identify use patterns for breeding and dispersing individuals by age, sex, and reproductive class. Population viability analysis models require much the same information. Finally, multiple-use management integration refers to trying to optimize the uses of wetlands, when only one (perhaps secondary) use may include waterbird management. Depending upon the ownership and primary land use of a particular parcel of land containing wetlands and/or water bodies, managing for waterbirds may be an \"easy sell\" (e.g., public natural resource lands) or a very contentious one, where wetlands are created for industrial, aquaculture or urban uses. In the latter case, careful planning and implementation require broad stakeholder participation and education.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Waterbirds","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","issn":"07386028","usgsCitation":"Erwin, R., 2002, Integrated management of waterbirds: Beyond the conventional: Waterbirds, v. 25, no.

The equations yield similar temperatures for the ??18O values of Globigerina bulloides and Neogloboquadrina pachyderma. In contrast, applying a single paleotemperature equation to G. bulloides and N. pachyderma ??18O yields different temperatures, which has been used to suggest that these species record the surface-to-thermocline temperature gradient. In Santa Barbara Basin, an isotopically distinct morphotype of G. bulloides dominates during glacial intervals and yields temperatures that appear too cold when using a paleotemperature equation calibrated for the morphotype common today. When a more appropriate paleotemperature equation is used for glacial G. bulloides, we obtain more realistic glacial temperatures. Glacial-interglacial temperature differences (G-I ??T) calculated in the present study indicate significant cooling (??? 8-10??C) throughout the Southern California Bight during the last glacial maximum (LGM). The magnitude of glacial cooling varies from ???8??C near the middle of the Southern California Bight (Tanner Basin and San Nicolas Basin) to ???9??C in the north (Santa Barbara Basin) and ???9.5-10??C in the south (Velero Basin and No Name Basin). Our temperature calculations agree well with previous estimates based on the modern analog technique. In contrast, studies using N. pachyderma coiling ratios, U37k??? indices, and transfer functions esfimate considerably warmer LGM temperatures and smaller G-I ??T. ?? 2002 Elsevier Science B.V.

In January, plasma androgens had declined in mature males and did not differ significantly from immature fish. By May all the hatchery fish were large enough to smolt and a proportion of the previously mature males had increased gill Na+,K+-ATPase activity. Therefore elevated androgens in the previous autumn do not prevent smolting.

A possible model that is consistent with our paleomagnetic results and the geologic evidence is that the Trinity Complex formed and migrated parallel to paleolatitude in the basin between Laurasia and Australia–East Antarctica as the Rodinian supercontinent began to break up.

In the absence of catalysts, all five amines underwent nucleophilic addition reactions with quinone and other carbonyl groups in the soil humic acid to form both heterocyclic and nonheterocyclic condensation products. Imine formation via 1,2-addition of the amines to quinone groups in the soil humic acid was significant with the diamines and TAT but not the monoamines. Horseradish peroxidase (HRP) catalyzed an increase in the incorporation of all five amines into the humic acid. In the case of the diamines and TAT, HRP also shifted the binding away from heterocyclic condensation product toward imine formation. A comparison of quantitative liquid phase with solid-state CP/MAS 15N NMR indicated that the CP experiment underestimated imine and heterocyclic nitrogens in humic acid, even with contact times optimal for observation of these nitrogens.

While no individuals bred as 2-year-olds during this period, about three-quarters of the young that survived and returned as 3-year-olds nested, and virtually all surviving birds had begun breeding by the time they reached 5 years of age. We found no evidence of temporal variation age of first breeding of birds from different cohorts. There was significant temporal variation in the annual survival of adults and the survival over the typical 3-year maturation period of prebreeding birds, with extremely low values for both groups from the 1991 breeding season. The estimated overwinter survival rate (0.62) for adults from 1991-1992 was about three-quarters the usual rate of about 0.83, but the low survival of fledglings from 1991 resulted in less than 25% of the otherwise expected number of young from that cohort returning as breeding birds; this suggests that fledglings suffered a greater proportional decrease in survival than did adults. The survival estimates of young from 1989 and 1990 show that these cohorts were not negatively influenced by the events that decimated the young from 1991, and the young from 1992 and 1993 had above-average survival estimates. The apparent decrease since 1996 in development of fidelity of new recruits to this site is suspected to be due mainly to nocturnal disturbance and predation of chicks causing low productivity.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Applied Statistics","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1080/02664760120108764","issn":"02664763","usgsCitation":"Spendelow, J., Nichols, J., Hines, J., Lebreton, J., and Pradel, R., 2002, Modelling postfledging survival and age- specific breeding probabilities in species with delayed maturity: A case study of Roseate Terns at Falkner Island, Connecticut: Journal of Applied Statistics, v. 29, no. 1-4, p. 385-405, https://doi.org/10.1080/02664760120108764.","startPage":"385","endPage":"405","numberOfPages":"21","costCenters":[],"links":[{"id":207963,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1080/02664760120108764"},{"id":233287,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"29","issue":"1-4","noUsgsAuthors":false,"publicationDate":"2010-05-14","publicationStatus":"PW","scienceBaseUri":"505a5c70e4b0c8380cd6fcc4","contributors":{"authors":[{"text":"Spendelow, J.

Reduced genetic variation may lead to inbreeding depression and we believe sea otter populations should be closely monitored for potential associated negative effects.</span></p>","language":"English","publisher":"Wiley","doi":"10.1046/j.1365-294x.2002.01599.x","usgsCitation":"Larson, S., Jameson, R., Etnier, M., Flemings, M., and Bentzen, P., 2002, Loss of genetic diversity in sea otters (Enhydra lutris) associated with the fur trade of the 18th and 19th centuries: Molecular Ecology, v. 11, p. 1899-1903, https://doi.org/10.1046/j.1365-294x.2002.01599.x.","productDescription":"5 p.","startPage":"1899","endPage":"1903","numberOfPages":"5","costCenters":[{"id":651,"text":"Western Ecological Research Center","active":true,"usgs":true}],"links":[{"id":132497,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"11","noUsgsAuthors":false,"publicationDate":"2002-09-23","publicationStatus":"PW","scienceBaseUri":"4f4e4a6fe4b07f02db640cfa","contributors":{"authors":[{"text":"Larson, S.","contributorId":62180,"corporation":false,"usgs":true,"family":"Larson","given":"S.","affiliations":[],"preferred":false,"id":316970,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Jameson, R.","contributorId":87485,"corporation":false,"usgs":true,"family":"Jameson","given":"R.","email":"","affiliations":[],"preferred":false,"id":316972,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Etnier, M.","contributorId":54949,"corporation":false,"usgs":true,"family":"Etnier","given":"M.","email":"","affiliations":[],"preferred":false,"id":316969,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Flemings, M.","contributorId":84318,"corporation":false,"usgs":true,"family":"Flemings","given":"M.","email":"","affiliations":[],"preferred":false,"id":316971,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Bentzen, P.","contributorId":49746,"corporation":false,"usgs":true,"family":"Bentzen","given":"P.","email":"","affiliations":[],"preferred":false,"id":316968,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}}
