The critical analytic tool is the geometric signature, a set of measures that describes topographic form well enough to distinguish among geomorphically disparate landscapes. Different surficial processes create topography with diagnostic forms that are recognizable in the field. The geometric signature abstracts those forms from contour maps or their DEMs and expresses them numerically. This multivariate characterization enables once-in-tractable problems to be addressed. The measures that constitute a geometric signature express different but complementary attributes of topographic form. Most parameters used here are statistical estimates of central tendency and dispersion for five major categories of terrain geometry; altitude, altitude variance spectrum, slope between slope reversals, and slope and its curvature at fixed slope lengths. As an experimental application of geometric signatures, two mapped terrain types associated with different processes of shallow landsliding in Marin County, California, were distinguished consistently by a 17-variable description of topography from 21??21 DEMs (30-m grid spacing). The small matrix is a statistical window that can be used to scan large DEMs by computer, thus potentially automating the mapping of contrasting terrain types. The two types in Marin County host either (1) slow slides: earth flows and slump-earth flows, or (2) rapid flows: debris avalanches and debris flows. The signature approach should adapt to terrain taxonomy and mapping in other areas, where conditions differ from those in Central California. ?? 1988 International Association for Mathematical Geology.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Mathematical Geology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisherLocation":"Kluwer Academic Publishers-Plenum Publishers","doi":"10.1007/BF00890333","issn":"08828121","usgsCitation":"Pike, R., 1988, The geometric signature: Quantifying landslide-terrain types from digital elevation models: Mathematical Geology, v. 20, no. 5, p. 491-511, https://doi.org/10.1007/BF00890333.","startPage":"491","endPage":"511","numberOfPages":"21","costCenters":[],"links":[{"id":205010,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1007/BF00890333"},{"id":220163,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"20","issue":"5","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505bac7fe4b08c986b32352b","contributors":{"authors":[{"text":"Pike, R.J.","contributorId":72814,"corporation":false,"usgs":true,"family":"Pike","given":"R.J.","email":"","affiliations":[],"preferred":false,"id":366852,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

The first is finding a robust estimator appropriate to the data characteristics expected in water-quality time series. The J. L. Hodges-E. L. Lehmann class of estimators is found to be robust in comparison to other nonparametric and moment-based estimators. A seasonal Hodges-Lehmann estimator is developed and shown to have desirable properties. Second, the effectiveness of various sampling strategies is examined using Monte Carlo simulation coupled with application of this estimator. The simulation is based on a large set of total phosphorus data from the Potomac River. To assure that the simulated records have realistic properties, the data are modeled in a multiplicative fashion incorporating flow, hysteresis, seasonal, and noise components. The results demonstrate the importance of balancing the length of the two sampling periods and balancing the number of data values between the two periods.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Water Resources Bulletin","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"American Water Resources Association","doi":"10.1111/j.1752-1688.1988.tb00899.x","issn":"00431370","usgsCitation":"Hirsch, R.M., 1988, Statistical Methods and Sampling Design for Estimating Step Trends in Surface-Water Quality: Water Resources Bulletin, v. 24, no. 3, p. 493-503, https://doi.org/10.1111/j.1752-1688.1988.tb00899.x.","startPage":"493","endPage":"503","numberOfPages":"11","costCenters":[],"links":[{"id":267759,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1111/j.1752-1688.1988.tb00899.x"},{"id":220665,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"24","issue":"3","noUsgsAuthors":false,"publicationDate":"2007-06-08","publicationStatus":"PW","scienceBaseUri":"505aaf8be4b0c8380cd87658","contributors":{"authors":[{"text":"Hirsch, Robert M. 0000-0002-4534-075X rhirsch@usgs.gov","orcid":"https://orcid.org/0000-0002-4534-075X","contributorId":2005,"corporation":false,"usgs":true,"family":"Hirsch","given":"Robert","email":"rhirsch@usgs.gov","middleInitial":"M.","affiliations":[{"id":436,"text":"National Research Program - Eastern Branch","active":true,"usgs":true},{"id":502,"text":"Office of Surface Water","active":true,"usgs":true},{"id":37316,"text":"WMA - Integrated Information Dissemination Division","active":true,"usgs":true},{"id":37778,"text":"WMA - Integrated Modeling and Prediction Division","active":true,"usgs":true}],"preferred":true,"id":366801,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

We use a Poisson process model for seismicity and define a process with quiescence as one with a particular type of piece-wise constant intensity function. From this model, we derive a statistic for testing stationarity against a 'quiescence' alternative. The large-sample null distribution of this statistic is approximated from simulated distributions of appropriate functionals applied to Brownian bridge processes. We point out the restrictiveness of the particular model we propose and of the quiescence idea in general. The fact that there are many point processes which have neither constant nor quiescent rate functions underscores the need to test for and describe nonuniformity thoroughly. We advocate the use of the quiescence test in conjunction with various other tests for nonuniformity and with graphical methods such as density estimation. ideally these methods may promote accurate description of temporal seismicity distributions and useful characterizations of interesting patterns. ?? 1988 Birkha??user Verlag.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Pure and Applied Geophysics PAGEOPH","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisherLocation":"Birkha??user-Verlag","doi":"10.1007/BF00879003","issn":"00334553","usgsCitation":"Matthews, M., and Reasenberg, P., 1988, Statistical methods for investigating quiescence and other temporal seismicity patterns: Pure and Applied Geophysics PAGEOPH, v. 126, no. 2-4, p. 357-372, https://doi.org/10.1007/BF00879003.","startPage":"357","endPage":"372","numberOfPages":"16","costCenters":[],"links":[{"id":205035,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1007/BF00879003"},{"id":220450,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"126","issue":"2-4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505b9731e4b08c986b31b934","contributors":{"authors":[{"text":"Matthews, M.V.","contributorId":70920,"corporation":false,"usgs":true,"family":"Matthews","given":"M.V.","email":"","affiliations":[],"preferred":false,"id":366887,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Reasenberg, P.A.","contributorId":19959,"corporation":false,"usgs":true,"family":"Reasenberg","given":"P.A.","email":"","affiliations":[],"preferred":false,"id":366886,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

With the passage of cold fronts (10–30 times per year) and hurricanes (once every 4 yrs), overwash events occur year round with varying degrees of frequency, intensity and geomorphological modification. This coastline consists of washover and dune surfaces that respond rapidly to overwash impact. The fine sand stored in washover deposits is easily reworked by aeolian processes into a variety of dune forms in the shore-zone that are vegetated rapidly. Geomorphological changes vary according to the position, ground elevation, and surface stability of the dunes. Independent factors are overwash surge elevations, beach gradient and the presence of pre-existing landforms. For ten years detailed surveys supplemented by aerial photographs and videotape surveys have recorded these changes. The analysis of these information sources provides insight into both the general evolution of this distinctive coastline and also the geomorphological interaction of dunes, beaches and washover deposits in different physiographic settings.</div></div></div></div></div><div id=\"preview-section-introduction\"><br></div>","language":"English","publisher":"Elsevier","doi":"10.1016/0025-3227(88)90020-5","issn":"00253227","usgsCitation":"Ritchie, W., and Penland, S., 1988, Rapid dune changes associated with overwash processes on the deltaic coast of South Louisiana: Marine Geology, v. 81, no. 1-4, p. 97-122, https://doi.org/10.1016/0025-3227(88)90020-5.","productDescription":"26 p.","startPage":"97","endPage":"122","numberOfPages":"26","costCenters":[],"links":[{"id":220449,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"81","issue":"1-4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a94d9e4b0c8380cd81663","contributors":{"authors":[{"text":"Ritchie, W.","contributorId":43628,"corporation":false,"usgs":true,"family":"Ritchie","given":"W.","email":"","affiliations":[],"preferred":false,"id":366778,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Penland, S.","contributorId":58778,"corporation":false,"usgs":true,"family":"Penland","given":"S.","email":"","affiliations":[],"preferred":false,"id":366779,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

Between 5 and 2 Ma, a pair of propagating rifts re-orientated the northern segment of Gorda Ridge by about 10?? clockwise, accommodating a clockwise shift in Pacific-Juan de Fuca plate motion that occurred around 5 Ma. Deformation of Gorda Plate, associated with southward decreasing spreading rates along southern Gorda Ridge, is accommodated by a combination of clockwise rotation of Gorda Plate crust, coupled with left-lateral motion on the original normal faults of the ocean crust. Segments of Gorda Plate which have rotated by different amounts are separated by narrow deformation zones across which sharp changes in ocean fabric trend are seen. Although minor lateral movement may occur on these NW to WNW structures, no major right-lateral movement, as predicted by previous models, is observed. ?? 1988 Kluwer Academic Publishers.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Marine Geophysical Researches","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisherLocation":"Kluwer Academic Publishers","doi":"10.1007/BF00310064","issn":"00253235","usgsCitation":"Masson, D., Cacchione, D., and Drake, D., 1988, Tectonic evolution of Gorda Ridge inferred from sidescan sonar images: Marine Geophysical Research, v. 10, no. 3-4, p. 191-204, https://doi.org/10.1007/BF00310064.","startPage":"191","endPage":"204","numberOfPages":"14","costCenters":[],"links":[{"id":204993,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1007/BF00310064"},{"id":219938,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"10","issue":"3-4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505ba45fe4b08c986b3202bb","contributors":{"authors":[{"text":"Masson, D.G.","contributorId":44160,"corporation":false,"usgs":true,"family":"Masson","given":"D.G.","email":"","affiliations":[],"preferred":false,"id":366818,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Cacchione, D.A.","contributorId":65448,"corporation":false,"usgs":true,"family":"Cacchione","given":"D.A.","affiliations":[{"id":520,"text":"Pacific Coastal and Marine Science Center","active":true,"usgs":true}],"preferred":false,"id":366820,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Drake, D.E.","contributorId":48150,"corporation":false,"usgs":true,"family":"Drake","given":"D.E.","email":"","affiliations":[],"preferred":false,"id":366819,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

Interpretations of downstream textural changes in deposits indicate that one lahar reached as far as Tygh Valley (65 km from the vent) before transforming into a lahar runout (hyperconcentrated flow). The runout inundated Tygh Valley and flowed into the Deschutes River, 75 km (flow path) from the volcano. A single lahar traveled more than 30 km down the Sandy River before transforming to a runout. Correlative sands and gravels are found as far as the apex of the Sandy River delta, more than 80 km from the volcano; these suggest that the flow underwent minimal attenuation of stage height throughout the length of Sandy River. Approximate dates ranging from 1760 A.D. to 1810 A.D. for various Old Maid-age events are inferred from dendrochronologic studies of old growth trees. There have been no apparent major topographic changes in the vent area since the end of Old Maid-age activity, enabling the events of the Old Maid eruptive period to be used as a model for future eruptive activity.</span></p>","language":"English","publisher":"Geological Society of America","doi":"10.1130/0016-7606(1987)99<845:ADCOTM>2.0.CO;2","usgsCitation":"Cameron, K.A., and Pringle, P.T., 1987, A detailed chronology of the most recent eruption period at Mount Hood, Oregon: Geological Society of America Bulletin, v. 99, p. 845-851, https://doi.org/10.1130/0016-7606(1987)99<845:ADCOTM>2.0.CO;2.","productDescription":"7 p.","startPage":"845","endPage":"851","numberOfPages":"7","costCenters":[{"id":615,"text":"Volcano Hazards Program","active":true,"usgs":true},{"id":617,"text":"Volcano Science Center","active":true,"usgs":true}],"links":[{"id":328616,"rank":2,"type":{"id":1,"text":"Abstract"},"url":"https://gsabulletin.gsapubs.org/content/99/6/845","text":"Article abstract","description":"Article abstract"},{"id":328619,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Oregon","otherGeospatial":"Mount Hood, Cascade Volcanic Arc in northern Oregon; approximately 50 miles east-southeast of Portland","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -121.96266174316406,\n              45.27053750018046\n            ],\n            [\n              -121.96266174316406,\n              45.47842910891348\n            ],\n            [\n              -121.5204620361328,\n              45.47842910891348\n            ],\n            [\n              -121.5204620361328,\n              45.27053750018046\n            ],\n            [\n              -121.96266174316406,\n              45.27053750018046\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"99","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"57d9232de4b090824ffa19ef","contributors":{"authors":[{"text":"Cameron, Kenneth A.","contributorId":9085,"corporation":false,"usgs":true,"family":"Cameron","given":"Kenneth","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":648749,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Pringle, P.

Water supplies presently are abundant, but ground-water levels continually fluctuate in response to natural factors and human-related stresses. A better understanding of the magnitude, duration, and frequency of past fluctuations, and the factors controlling these fluctuations may help anticipate future changes in ground-water levels.</p>\n<p>This report presents the results of statistical analyses of historical ground-water level fluctuations in Wisconsin. Short- and long-term fluctuations are discussed in terms of their relation to components of the hydrogeologic system.</p>\n<p>Water-level measurements from 124 wells with at least 20 years of record each were used in the study. The mean, highest and lowest monthly mean, median, and selected quantiles were obtained using the SAS Proc Univariate procedure. The frequency values from the Univariate table were used to construct stage-duration graphs. Pearson Type ill frequency analyses were used to obtain probabilities of exceedance of particular water levels. The data were divided into seasonal data sets for each well. The stage-duration and Pearson Type III analyses are based on past fluctuations but may be useful for estimating future water-level changes under similar conditions.</p>\n<p>Multiple-regression analyses were run on data from groups of wells representing different ground-water districts. The SAS Proc Stepwise method was used. The regression model used average annual amplitude as the dependent variable and mean water level, mean annual precipitation, standard deviation of the seasonal mean precipitation, aquifer type, and topographic setting as the independent variables.This procedure produced different regression equations for each hydrogeologic district. Regression analyses also were done on data from groups of wells representing different aquifers. These regression models used average annual amplitude as the dependent variable and mean water level, topographic setting, and standard deviation of seasonal mean precipitation as the independent variables.</p>\n<p>Because of the many factors influencing ground-water level fluctuations, it was difficult to obtain a regression model that accurately reproduced average annual amplitude. The results of the regression analyses are helpful in recognizing the important variables; however, the equations are not effective in predicting the amplitude of a particular well because local conditions were omitted in the regional analyses.</p>\n<p>Hydrographs of average annual water level and frequency distribution analyses of annual maximum and minimum water levels were inspected for possible long-term trends. Analysis of annual maximum and minimum water levels indicates several periods in the annual cyclic fluctuations-two periods of recession (winter and summer), and two periods of rising levels (spring and fall). Usually, water levels are lowest in late winter and highest in spring for every annual cycle. The summer-fall minimum and the fall maximum are less distinct and do not occur every year.</p>\n<p>A composite frequency analysis of extreme annual water levels on 71 of the wells shows that the lowest levels most frequently occur in December, February, or March. However, the record low usually occurs in August, September, or October during drought. Ground-water levels most often peak in May, April, or June. In the fan they may peak from September through December, depending upon complexities of meteorological, geomorphological, and geological factors.</p>\n<p>The long-term cyclicity of ground-water level fluctuations is shown on hydrographs of wells Sw-7, Ln-25a, Mt-7, Ju-8, and Ju-98. Seasonal variations that tend to obscure the long-term trends are eliminated by plotting the average annual water levels. The hydrographs are similar even though the wells are 80 to 100 miles apart and constructed in different geologic materials. The long-term trends and the duration of the cycles apparently depend little on the location and on the lithologic composition of the aquifers, but rather on precipitation. The hydrographs show several periods of welldefined peaks and lows. The ground-water levels reached peaks in 1946, 1952, 1960, 1966, 1973, 1979. The average interval between these peaks is 6.6 years. The low levels occurred in 1949, 1955-59, 1964, 1970, and 1977; average interval between the low levels is 7.0 years, which is similar to that for the high levels.</p>\n<p>Long-term trends are apparent on hydrographs of wells Br-46, Mr-2S, Pt-276, Ro-3, and Ve-8. The trend of average annual water levels has been generally increasing since the late 1950's and is in general agreement with the increasing trend of precipitation. Hydrographs of well Ve-8, which has the longest period of record in Wisconsin, indicate that the generally rising trend started even earlier at the end of an extensive drought period in the 1930's.</p>","language":"English","publisher":"Wisconsin Geological & Natural History Survey","collaboration":"Prepared in cooperation with the University of Wisconsin Extension-Geological and Natural

GPS provided the most accurate navigational control, but was functional for only about 12 hours each day. The transit satellite system operated throughout the cruise and provided relatively accurate positions when GPS was not operational. The Mini-Ranger stations proved to be unreliable because of problems at the shore stations and Loran-C operated only on the north side of the islands, at times in only the range-range mode.</p><p>Because the gravity program required accurate data and strict navigation control, some lines had to be run more than once or run with a following sea in a westerly direction only. Consequently, there is tight line spacing in some areas. The Uniboom high-resolution reflection data are good to poor in the shelf areas around Puerto Rico but are generally poor over the predominantly carbonate sediments around the Virgin Islands.

In most cases, the absolute stereochemistry at the <i>cis</i>-B/C ring junction of the rotenoidal antipodes can be related to their elution order. Generally, the 6a&alpha;,12a&alpha;-enantiomers were more strongly retained by the chiral substrate than their corresponding optical antipodes. The elution-configuration relationship provides potential utility for predicting the absolute configuration of related rotenoidal compounds. Chiral phase hplc on amino-acid-bonded-silica yielded results explicable in terms of Pirkle's bonding schemes for chiral recognition. Resolution data for 12a-hydroxy-, 12a-methoxy-, and 12-hydroxyiminorotenoids further corroborate the mechanistic rationale, and demonstrate that nonpolar &pi;-&pi; interactions appeared to be important for enantiomeric separation on helic poly-triphenylmethylacryl-ate-silica (CPOT). In the latter system, steric effects and conformational factors in association with the modification of E-ring structures might play significant roles in the chiral separation process in view of the reversal to the elution order observed for all methoxylated rotenoids and elliptone derivatives including the parent deguelin. The unique separability (&alpha; = 1.44) of 12a-hydroxyelliptone on CPOT was suggestive of structural effects of the 5-side chain on the resolution of the rotenoids having a five-membered-E-ring. The results obtained with two different types of chiral phases are complementary and useful for optical resolution of a wide variety of natural and synthetic rotenoidal compounds.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Heterocyclic Chemistry","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Wiley","publisherLocation":"Hoboken, NJ","doi":"10.1002/jhet.5570240358","collaboration":"None","usgsCitation":"Abidi, S.L., 1987, Optical resolution of rotenoids: Journal of Heterocyclic Chemistry, v. 24, no. 3, p. 845-852, https://doi.org/10.1002/jhet.5570240358.","productDescription":"8 p.","startPage":"845","endPage":"852","numberOfPages":"8","costCenters":[{"id":606,"text":"Upper Midwest Environmental Sciences Center","active":true,"usgs":true}],"links":[{"id":259911,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":259895,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1002/jhet.5570240358","linkFileType":{"id":5,"text":"html"}}],"volume":"24","issue":"3","noUsgsAuthors":false,"publicationDate":"2009-04-06","publicationStatus":"PW","scienceBaseUri":"505a6ed5e4b0c8380cd75816","contributors":{"authors":[{"text":"Abidi, S.

Separations of optical isomers were achieved in various degrees depending largely upon the rotenoidal structures and the CSP types employed. Enantiomers of all but elliptone compounds were separable on &beta;-cyclodextrin-bonded silica (CDS). Without exception, the 12a-hydroxyrotenoid antipodes were resolved on Pirkle's phenylglycine-bonded silica (PGS) despite unsuccessful attenmpts to resolve the type I rotenoidal racemates. Conversely, optical resolution of the latter rotenoids was accomplished by using a helical polytriphenylmethylacrylate-coated silica (TPS) column and the observed separation factors (&alpha; values) ranged from 1.14 to 1.90. The results from HPLC of type II rotenoids on TPS (&alpha; = 1.00&ndash;1.63) suggested that variations in E-ring structures had profound influence on the resolution outcome. Conjugated double bonds on the E-ring and the desisopropylation of the five-membered E-ring ot type II rotenoids appeared to be important structural features for chiral recognition involving the TPS substrate.

The data come primarily from intensely faulted Miocene tuffaceous sedimentary rocks in Hampel Wash, which is bounded on the north by the Quaternary ENE trending Rock Valley fault and on the south by a parallel unnamed fault. Data from faults with known sense of displacement exhibit a bimodal distribution of slip angles (rakes). Faults exhibiting steep rakes (typically 75° to 90°) cluster about a N30°–35°E strike; most dip 65° to 80°. Faults having shallow rakes (generally less than 20°) exhibit a wide range of strikes (from N6°W to N80°E) and mostly dip between 80° and 90°. The predominant N30°–35°E strike of the steep-rake faults and the quasi-conjugate nature of a consistent subset of the shallowrake faults suggest a maximum horizontal stress orientation of about N30°–35°E and a least horizontal principal stress direction of N55°–60°W. Analysis of the data using a least squares iterative inversion to determine a mean deviatoric principal stress tensor indicates a normal-faulting stress regime (S</span><sub>1</sub><span>&nbsp;vertical) with principal stress axes in approximately horizontal and vertical directions (S</span><sub>1</sub><span>, trend = N 19°E and plunge = 82°N; S</span><sub>2</sub><span>, N30°E and 8°S; and S</span><sub>3</sub><span>, N60°W and 2°E). The maximum horizontal stress, S</span><sub>2</sub><span>, was found to be nearly intermediate in magnitude between S</span><sub>1</sub><span>&nbsp;and S</span><sub>3</sub><span>. The N60°W least horizontal principal stress orientation obtained from the fault-slip inversion agrees with our geometric analysis of the data and is consistent with a modern least horizontal principal stress orientation of N50°–70°W inferred from earthquake focal mechanisms, well bore breakouts, and hydraulic fracturing measurements in the vicinity of the Nevada Test Site. This solution fits all the data well, except for a subset of strike-slip faults that strike N30°–45°E, subparallel to the normal faults of the data set. Nearly pure dip-slip and pure strike-slip movement on similarly oriented faults, however, cannot be accommodated in a single stress regime. Superposed sets of striae observed on some faults suggest temporal rotations of the regional stress field or local rotations within the region of the fault zone.</span></p>","language":"English","publisher":"American Geophysical Union","doi":"10.1029/TC006i002p00089","issn":"02787407","usgsCitation":"Frizzell, V.A., and Zoback, M., 1987, Stress orientation determined from fault slip data in Hampel Wash area, Nevada, and its relation to contemporary regional stress field: Tectonics, v. 6, no. 2, p. 89-98, https://doi.org/10.1029/TC006i002p00089.","productDescription":"10 p.","startPage":"89","endPage":"98","costCenters":[],"links":[{"id":225275,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Nevada","otherGeospatial":"Hampel Wash area","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -116.41380395515019,\n              37.34547735717791\n            ],\n            [\n              -116.41380395515019,\n              35.934968337002616\n            ],\n            [\n              -114.73066822180856,\n              35.934968337002616\n            ],\n            [\n              -114.73066822180856,\n              37.34547735717791\n            ],\n            [\n              -116.41380395515019,\n              37.34547735717791\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","volume":"6","issue":"2","noUsgsAuthors":false,"publicationDate":"2010-07-26","publicationStatus":"PW","scienceBaseUri":"505b9b60e4b08c986b31ce34","contributors":{"authors":[{"text":"Frizzell, V.

Ambiguities arise when statistical designs are unbalanced, and in particular when not all combinations of design factors are represented in the data. This paper clarifies the relationship among hypothesis testing, statistical modelling and computing procedures in ANOVA for unbalanced data. A simple two-factor fixed effects design is used to illustrate three common parametrizations for ANOVA models, and some associations among these parametrizations are developed. Biologically meaningful hypotheses for main effects and interactions are given in terms of each parametrization, and procedures for testing the hypotheses are described. The standard statistical computing procedures in ANOVA are given along with their corresponding hypotheses. Throughout the development unbalanced designs are assumed and attention is given to problems that arise with missing cells.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Applied Stochastic Models and Data Analysis","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1002/asm.3150030403","usgsCitation":"Williams, B.K., 1987, The use of analysis of variance procedures in biological studies: Applied Stochastic Models and Data Analysis, v. 3, no. 4, p. 207-226, https://doi.org/10.1002/asm.3150030403.","productDescription":"207-226","startPage":"207","endPage":"226","numberOfPages":"20","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":17817,"rank":200,"type":{"id":11,"text":"Document"},"url":"https://dx.doi.org/10.1002/asm.3150030403","linkFileType":{"id":5,"text":"html"}},{"id":196573,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"3","issue":"4","noUsgsAuthors":false,"publicationDate":"2006-08-31","publicationStatus":"PW","scienceBaseUri":"4f4e4a5fe4b07f02db634a14","contributors":{"authors":[{"text":"Williams, B.

Inferences are based on analyses of banding and recovery data from both winter and preseason banding period.  The primary wintering range of the mallard was dividded into 45 minor reference areas and 15 major reference areas which were used to summarize winter banding data.  Descriptive tables and figures on the recovery distributions of winter-banded mallards are presented.</p>\n<br/>\n<p>Using winter recoveries of preseason-banded mallards, we found apparent differences between recovery distribution of young versus adult birds from the same breeding ground reference areas.  However, we found no sex-specific differences in winter recovery distribution patterns.  Winter recovery distributions of preseason-banded birds also provided evidence that mallards exhibited some degree of year-to-year variation in wintering ground location.  The age- and sex-specificity of such variation was tested using winter recoveries of winter-banded birds, and results indicated that subadult (first year) birds were less likely to return to the same wintering grounds the following year than adults.  Winter recovery distributions of preseason-banded mallards during 1950-58 differed from distributions in 1966-76.  These differences could have resulted from either true distributional shifts or geographic changes in hunting pressure.</p>\n<br/>\n<p>Survival and recovery rates were estimated from winter banding data.  We found no evidence of differences in survival or recovery rates between subadult and adult mallards.  Thus, the substantial difference between survival rates of preseason-banded young and adult mallards must result almost entirely from higher mortality of young birds during the approximate period, August-January.  Male mallards showed higher survival than females, corroborating inferences based on preseason data.  Tests with winter banding and band recovery data indicated some degree of year-to-year variation in both survival and recovery rates, a result again consistent with inference from preseason data.  Some evidence indication geographic variation in survival rates; however, there were no consistent directional differences between survival rates of mallards from adjacent northern versus southern areas, or eastern versus western areas.  In some comparisons, Central Flyway mallards exhibited slightly higher survival rates than mallards from other flyways.</p>\n<br/>\n<p>Weighted mean estimates of continental survival rates were computed for the period 1960-77 from both winter banding data and preseason banding of adults.  Resulting estimates differed significantly for males, but not for females, and the magnitude of the difference between point estimates was relatively small, even for males.  The direction of the difference between these estimates was predicted correctly from previous work on the effects of heterogeneous survival an d recovery rates on band recovery model estimates.  The similarity of survival estimates from these two independent data sets supports the believe that biases in these estimates are relatively small.</p>","language":"English","publisher":"U.S. Fish and Wildlife Service","publisherLocation":"Washington, D.C.","usgsCitation":"Nichols, J., and Hines, J., 1987, Population ecology of the mallard VIII: Winter distribution patterns and survival rates of winter-banded mallards: Resource Publication 162, ii, 154 p.","productDescription":"ii, 154 p.","numberOfPages":"161","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":290099,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":290098,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/unnumbered/5230162/report.pdf"}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4ad6e4b07f02db68433e","contributors":{"authors":[{"text":"Nichols, James D. 0000-0002-7631-2890 jnichols@usgs.gov","orcid":"https://orcid.org/0000-0002-7631-2890","contributorId":405,"corporation":false,"usgs":true,"family":"Nichols","given":"James D.","email":"jnichols@usgs.gov","affiliations":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"preferred":false,"id":343640,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Hines, James E. jhines@usgs.gov","contributorId":3506,"corporation":false,"usgs":true,"family":"Hines","given":"James E.","email":"jhines@usgs.gov","affiliations":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"preferred":false,"id":343641,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

On nautical charts, we measured four island characteristics (area, length, width, shape), three isolation factors (distances to nearest island, mainland, and a water barrier),, and two variables related to potential feeding habitat within 5 km of the center of the colony (wetland area and land-water interface, i.e., the linear distance between the marsh/upland and all water bodies within the same 5-km radius). One univariable and five multivariable .procedures were used to determine which habitat features were best related to population size .(all species combined). Multicollinearity problems among the variables limited interpretation for most procedures. Both univariable and the multivariable procedures indicated that land-water interface was the most important of the nine variables, but for all models, less than 10% of the total variance was explained (rz is less than 0.10). The size of the colony was not related to the amount of wetland area (within 5-km).per se.  Colony data showed better 'structure' when examined on the basis of geographic and disturbance gradients. Population sizes of colonies near man-altered habitats were compared with those surrounded by relatively natural habitats in three geographic zones: north, middle, and south. Significant differences were found in colony size among the three zones (south largest) and between disturbance types. Surprisingly, in all three zones, colonies near man-altered areas were larger on average than those near more natural habitats in this region. A possible reason for this difference is suggested.","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"Waterfowl and Wetlands Symposium:  Proceedings of a Symposium on Waterfowl and Wetlands Management in the Coastal Zone of the Atlantic Flyway","largerWorkSubtype":{"id":4,"text":"Other Government Series"},"language":"English","publisher":"Delaware Coastal Management Program, Delaware Department of Natural Resources and Environment Control","publisherLocation":"Dover, Delaware","usgsCitation":"Erwin, R., Spendelow, J., Geissler, P., and Williams, B.K., 1987, Relationships between nesting populations of wading birds and habitat features along the Atlantic Coast, chap. <i>of</i> Waterfowl and Wetlands Symposium:  Proceedings of a Symposium on Waterfowl and Wetlands Management in the Coastal Zone of the Atlantic Flyway, p. 56-67.","productDescription":"v, 522","startPage":"56","endPage":"67","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":201083,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4ac8e4b07f02db67c097","contributors":{"editors":[{"text":"Whitman, William R.","contributorId":111631,"corporation":false,"usgs":true,"family":"Whitman","given":"William","email":"","middleInitial":"R.","affiliations":[],"preferred":false,"id":506387,"contributorType":{"id":2,"text":"Editors"},"rank":1},{"text":"Meredith, William H.","contributorId":112289,"corporation":false,"usgs":true,"family":"Meredith","given":"William","email":"","middleInitial":"H.","affiliations":[],"preferred":false,"id":506388,"contributorType":{"id":2,"text":"Editors"},"rank":2}],"authors":[{"text":"Erwin, R.M.","contributorId":57396,"corporation":false,"usgs":true,"family":"Erwin","given":"R.M.","email":"","affiliations":[],"preferred":false,"id":328313,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Spendelow, J.
