Volcanic sediments, now mostly bentonites and bentonitic mudstones, occur throughout the Late Neogene and Quaternary Siwalik Group of northern Pakistan. A number of these deposits have been dated by the fission-track method, utilizing zircon phenocrysts from these deposits, and provide the chronometric constraints upon which a paleomagnetic stratigraphy is developed for the Siwalik Group. Notable in the occurrence of these altered tuff horizons is an apparent mode in their stratigraphic development from approximately 3.0 to 1.5 m.y. B.P. which coincides with the period of activity of the Dacht-e-Nawar volcanic complex of east-central Afghanistan. Fission-track ages of certain tuffs for critical areas of northern Pakistan are reported herein.

In the U.S. Geological Survey oilspill trajectory analysis model, the surface drift component is assumed to be 3.5% of the wind speed and is rotated 20 degrees clockwise to account for Coriolis effects in the Northern Hemisphere. Field and laboratory data suggest, however, that the deflection angle of the surface drift current can be highly variable. An empirical formula, based on field observations and theoretical arguments relating wind speed to deflection angle, was used to calculate a new deflection angle at each time step in the model. Comparisons of oilspill contact probabilities to coastal areas calculated for constant and variable deflection angles showed that the model is insensitive to this changing angle at low wind speeds. At high wind speeds, some statistically significant differences in contact probabilities did appear.

A series of contour maps of Mars is being compiled by these new methods using a wide variety of Viking Orbiter photographs, to provide the planetary research community with topographic information.

These techniques should help resource managers who are concerned with such river systems to establish sound environmental programs.
\nDiscussion of each technique or group of techniques include (1) situation to be mitigated or enhanced; (2) description of technique; (3) impacts on the environment; (4) costs; and (5) evaluation for use on the Upper Mississippi River Systems. The techniques are divided into four primary categories: Bank Stabilization Techniques, Dredging and Disposal of Dredged Material, Fishery Management Techniques, and Wildlife Management Techniques. Because techniques have been grouped by function, rather than by structure, some structures are discussed in several contexts. For example, gabions are discussed for use in revetments, river training structures, and breakwaters.
\nThe measures covered under Bank Stabilization Techniques include the use of riprap revetments, other revetments, bulkheads, river training structures, breakwater structures, chemical soil stabilizers, erosion-control mattings, and filter fabrics; the planting of vegetation; the creation of islands; the creation of berms or enrichment of beaches; and the control of water level and boat traffic. The discussions of Dredging and the Disposal of Dredged Material consider dredges, dredging methods, and disposal of dredged material. The following subjects are considered under Fishery Management Techniques: fish attractors; spawning structures; nursery ponds, coves, and marshes; fish screens and barriers; fish passage; water control structures; management of water levels and flows; wing dam modification; side channel modification; aeration techniques; control of nuisance aquatic plants; and manipulated of fish populations. Wildlife Management Techniques include treatments of artificial nest structures, island creation or development, marsh creation or development, greentree reservoirs and mast management, vegetation control, water level control, and revegetation.

Zeolites (in particular clinoptilolite) are present in some tuff beds throughout much of the study area, and this resource potential is probably moderate to high. Stream-sediment sampling suggests that the Muddy Mountains area has little potential for mineral deposits of metals (other than lithium). Clay minerals are mined at one locality in the (!rea (see map). Building stone and silica sand have moderate to low potential in some places. Oil and gas potential within the study area is low, but complete evaluation of its potential is not possible without drilling.

During 1980, 98 teleseismic events were recorded at as many as 53 sites in this area. P-wave residuals were calculated relative to a network-wide average residual for each event and are displayed on maps of the stations for each of four event-azimuth quadrants. Fluctuations in these map-patterns of residuals with approach azimuth combined with results of linear, three-dimensional inversions of some 2887 residuals indicate the following characteristics of the velocity structure of the southern Nevada region: 1) a low-velocity body exists in the upper crust 50 km northeast of Beatty, Nevada, near the Miocene Timber Mountain-Silent Canyon caldera complex. Another highly-localized low-velocity anomaly occurs near the southwest corner of the Nevada Test Site (NTS). These two anomalies seem to be part of a low-velocity trough extending from Death Valley, California, to about 50 km north of NTS. 2) There is a high-velocity body in the mantle between 81 and 131 km deep centered about i0 km north of the edge of the Timber Mountain caldera, 3) a broad low-velocity body is delineated between 81 and 131 km deep centered about 30 km north of Las Vegas, 4) there is a monotonic increase in travel-time delays from west to east across the region, probably indicating an eastward decrease in velocity, and lower than average velocities in southeastern Nevada below 31 km, and 5) considerable complexity in three-dimensional velocity structure exists in this part of the southern Great Basin. \r\n\r\nInversions of teleseismic P-wave travel-time residuals were also performed on data from 12 seismometers in the immediate vicinity of the Nevada Test Site to make good use of the closer station spacing i in that area. Results of these inversions show more details of the velocity structure but generally the same features as those found in the regional study.","language":"ENGLISH","publisher":"U.S. Geological Survey,","doi":"10.3133/ofr82409","usgsCitation":"Monfort, M.E., and Evans, J.R., 1982, Three-dimensional modeling of the Nevada Test Site and vicinity from teleseismic P-wave residuals: U.S. Geological Survey Open-File Report 82-409, 70 p. :ill. ;28 cm., https://doi.org/10.3133/ofr82409.","productDescription":"70 p. :ill. ;28 cm.","costCenters":[],"links":[{"id":142336,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1982/0409/report-thumb.jpg"},{"id":38215,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1982/0409/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a53e4b07f02db62b857","contributors":{"authors":[{"text":"Monfort, Mary E.","contributorId":93491,"corporation":false,"usgs":true,"family":"Monfort","given":"Mary","email":"","middleInitial":"E.","affiliations":[],"preferred":false,"id":161296,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Evans, John R. jrevans@usgs.gov","contributorId":529,"corporation":false,"usgs":true,"family":"Evans","given":"John","email":"jrevans@usgs.gov","middleInitial":"R.","affiliations":[{"id":237,"text":"Earthquake Science Center","active":true,"usgs":true}],"preferred":true,"id":161295,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}} ,{"id":36547,"text":"fwsobs82_10_30 - 1982 - Habitat Suitability Index Models: Beaver","interactions":[],"lastModifiedDate":"2022-02-15T14:38:05.926312","indexId":"fwsobs82_10_30","displayToPublicDate":"1994-01-01T00:00:00","publicationYear":"1982","noYear":false,"publicationType":{"id":18,"text":"Report"},"publicationSubtype":{"id":1,"text":"Federal Government Series"},"seriesTitle":{"id":20,"text":"FWS/OBS","active":false,"publicationSubtype":{"id":1}},"seriesNumber":"82/10.30","subseriesTitle":"Habitat Suitability Index","title":"Habitat Suitability Index Models: Beaver","docAbstract":"Habitat preferences of the beaver (Castor canadensis) are described in this publication, which is one of a series of Habitat Suitability Index (HSI) models.

The wilderness study area has a moderately high potential for geothermal resources, a low to moderate potential for base metal or precious metal resources in middle to upper Tertiary volcanic rocks, essentially no oil, gas, or coal potential, and a largely unassessable potential for metal deposits related to Laramide igneous intrusions in pre-Tertiary or lower Tertiary rocks that underlie the area. The contiguous roadless area, which borders the New Mexico half of the wilderness study area, mainly on the north side of the San Francisco River, has a low to moderate potential for molybdenum or copper deposits related to intrusive igneous rocks in the core of a volcano of dacitic composition at Goat Basin.

In the salt-dome basin the Tokio Formation and Brownstown Marl (Austin aquifer in this report), and Nacatoch Sand of Late Cretaceous age and the Wilcox Group, Carrizo Sand, Sparta Sand, and Cockfield Formation of Tertiary age contain regional aquifers within the maximum potential repository depth of 3,000 feet. The Cretaceous units contain saltwater throughout the basin. The Tertiary units contain freshwater to varying distances downdip from outcrop areas in the basin. Natural flow directions and rates of movement of groundwater have been changed in the salt-dome basin by the withdrawl of freshwater and by the injection of wastes (principally oil-field brines) into saline aquifers. Except for the Sparta aquifer, ground-water flow directions are not well known because of a lack of potentiometric data. A regional test-drilling program, to collect the data needed to document concepts of the flow system and to quantify inputs to the planned ground-water flow model, has been proposed. The Sparta aquifer is being modeled because data are available for the unit. As regional test drilling provides data on other units, will be added to the model developed for the Sparta aquifer.

A conceptual model of the full system is developed and a subregion selected for quantitative modeling. By invoking the .Boussinesq approximation, valid for describing the natural flow of heat and mass in a liquid hydrothermal system, it is found practical to carry computer simulations far enough in time to ensure that steady-state conditions are obtained. Initial calculations for an axisymmetric model approximating the system demonstrate that the vertical formation permeability of the deep East Mesa system must be very low (kv ~ 0.25 to 0.5 md). Since subsurface temperature and surface heat flow data exhibit major deviations from the axisymmetric approximation, exploratory three-dimensional calculations are performed to assess the effects of various mechanisms which might operate to produce such observed asymmetries. A three-dimensional model evolves from this iterative data synthesis and computer analysis which includes a hot fluid convective source distributed along a leaky fault radiating northward from the center of the hot spot and realistic variations in the reservoir formation properties.","language":"ENGLISH","publisher":"U.S. Geological Survey,","doi":"10.3133/ofr82980","usgsCitation":"Riney, T.D., Pritchett, J., and Rice, L., 1982, Integrated model of the shallow and deep hydrothermal systems in the East Mesa area, Imperial Valley, California: U.S. Geological Survey Open-File Report 82-980, 118 p., ill., maps ;28 cm., https://doi.org/10.3133/ofr82980.","productDescription":"118 p., ill., maps ;28 cm.","costCenters":[],"links":[{"id":144916,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1982/0980/report-thumb.jpg"},{"id":38644,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1982/0980/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e499ee4b07f02db5bcb4b","contributors":{"authors":[{"text":"Riney, T.

Analyses of rock samples from a drill hole 15 mi (24 km) south of the area showed anomalous amounts of several metals in the Derby-Doerun (usage of the Missouri Geological Survey), Potosi, and Eminence Dolomites, which suggests that these units as well as the subsurface Ordovician carbonate units may have a potential for zinc-lead mineralization in the wilderness. Also, a high-amplitude magnetic anomaly along the northwest side of the wilderness suggests a potential for a small to moderate-sized magnetite (iron ore) deposit in the Precambrian basement rocks at a depth of at least 2,100 ft (640 m) below the surface, probably at least partly outside the boundary of the wilderness. In both cases the significance of the potential cannot be evaluated without deep drilling. In the case of the possible magnetite deposit, drilling should be preceded by a detailed magnetic survey to delineate the anomaly more clearly. The wilderness has little potential for resources of industrial minerals because they are readily available elsewhere in the region, and no known potential for energy resources.

Bear and Blue Creek basins are underlain predominantly by relatively impermeable consolidated rocks in the Pottsville Formation. Turkey and Yellow Creek basins are underlain predominantly by permeable unconsolidated rocks in the Coker Formation. \r\n\r\nWell yields from the Pottsville Formation generally range from 0 to 5 gallons per minute and those from the Coker Formation generally range from 5 to 100 gallons per minute. With the exception of locally objectional concentrations of dissolved iron and manganese, ground water in the basins is suitable for most uses. \r\n\r\nStreamflow distribution reflects seasonal precipitation. Storm runoff is characterized by concentrated peakflows of short duration that rapidly recede to low flow. Streams draining basins underlain mainly by the Pottsville Formation frequently go dry, whereas those draining basins underlain chiefly by the Coker Formation have well-sustained low flows.\r\n\r\nSurface water is generally acidic and low in dissolved solids. Water in streams draining basins underlain chiefly by the Pottsville Formation is slightly more mineralized and less acidic than water in streams draining areas underlain chiefly by the Coker Formation. Climatic, physiographic, hydrologic, and land-use data are analyzed by regressions to derive relations for estimating water quality in streams draining mined and unmined areas. \r\n\r\nThe impacts of mining on the hydrologic systems are identified as increased erosion and sedimentation, baseflow augmentation, decline in groundwater levels, and degradation of water quality. \r\n\r\nA digital model was calibrated to simulate streamflow for Bear, Blue, and Yellow Creeks under unmined conditions. The model, when calibrated and verified under mined and unmined conditions, can be coupled with developed water-quality relationships. This will permit a general examination of .surface-water characteristics (quantity and quality), and estimation of hydrologic impacts that will result from surface mining.","language":"ENGLISH","publisher":"U.S. Geological Survey,","doi":"10.3133/ofr82105","usgsCitation":"Puente, C., and Newton, J., 1982, Hydrology of potential mining areas in the Warrior coal field, Alabama: U.S. Geological Survey Open-File Report 82-105, 117 p., 10 over-size sheets, ill., maps ;28 cm., https://doi.org/10.3133/ofr82105.","productDescription":"117 p., 10 over-size sheets, ill., maps ;28 cm.","costCenters":[],"links":[{"id":112942,"rank":410,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1982/0105/plate-figure_02.pdf","size":"2786","linkFileType":{"id":1,"text":"pdf"}},{"id":112943,"rank":411,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1982/0105/plate-figure_03.pdf","size":"3319","linkFileType":{"id":1,"text":"pdf"}},{"id":112944,"rank":412,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1982/0105/plate-figure_07.pdf","size":"507","linkFileType":{"id":1,"text":"pdf"}},{"id":112945,"rank":413,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1982/0105/plate-figure_16.pdf","size":"645","linkFileType":{"id":1,"text":"pdf"}},{"id":112946,"rank":414,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1982/0105/plate-figure_17.pdf","size":"485","linkFileType":{"id":1,"text":"pdf"}},{"id":112947,"rank":415,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1982/0105/plate-figure_18.pdf","size":"263","linkFileType":{"id":1,"text":"pdf"}},{"id":112948,"rank":416,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1982/0105/plate-figure_20.pdf","size":"2434","linkFileType":{"id":1,"text":"pdf"}},{"id":112949,"rank":417,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1982/0105/plate-figure_21.pdf","size":"3675","linkFileType":{"id":1,"text":"pdf"}},{"id":112950,"rank":418,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1982/0105/plate-figure_22.pdf","size":"2647","linkFileType":{"id":1,"text":"pdf"}},{"id":143601,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1982/0105/report-thumb.jpg"},{"id":38562,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1982/0105/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a0ee4b07f02db5fdaff","contributors":{"authors":[{"text":"Puente, Celso","contributorId":36140,"corporation":false,"usgs":true,"family":"Puente","given":"Celso","email":"","affiliations":[],"preferred":false,"id":161909,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Newton, J.G.","contributorId":71552,"corporation":false,"usgs":true,"family":"Newton","given":"J.G.","email":"","affiliations":[],"preferred":false,"id":161910,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}} ,{"id":10761,"text":"ofr82865 - 1982 - An evaluation of Idaho stream-gaging networks","interactions":[],"lastModifiedDate":"2012-02-02T00:06:24","indexId":"ofr82865","displayToPublicDate":"1994-01-01T00:00:00","publicationYear":"1982","noYear":false,"publicationType":{"id":18,"text":"Report"},"publicationSubtype":{"id":5,"text":"USGS Numbered Series"},"seriesTitle":{"id":330,"text":"Open-File Report","code":"OFR","onlineIssn":"2331-1258","printIssn":"0196-1497","active":true,"publicationSubtype":{"id":5}},"seriesNumber":"82-865","title":"An evaluation of Idaho stream-gaging networks","docAbstract":"Network Analysis for Regional Information (NARI) and the Cost-Effectiveness Procedure were tested by applying them to stream-gaging networks in Idaho.

Studies are now in progress in Austin, Houston, and San Antonio.
The U.S. Geological Survey, in cooperation with the city of Houston, began studies in the Houston metropolitan area in 1964. The program was expanded in 1968 to include collection of water-quality data. The objectives of the Houston urban-hydrology study are as follows:
This report, the sixteenth in a series of reports to be published annually, is primarily applicable to objective 2. The report presents hydro!ogic data collected in the Houston urban area for the 1979 water year (October 1, 1978 to September 30, 1979).
A report by Johnson and Sayre (1973) utilized records collected from 1965 to 1969 to make a study of the effects of urbanization on floods in the Houston area. The report also summarizes various basin parameters. A report by Waddell, Massey, and Jennings (1979) presents data on computed runoff from the Houston area and computed concentrations and loads of selected waterquality constituents combined in the inflow to Galveston Bay. The study utilized a variation of the \"STORM\" model developed by the Hydro!ogic Engineering Center of the U.S. Army Corps of Engineers. A report prepared by Li scum and Massey (1980) presents a technique for estimating the magnitude and frequency of floods in the Houston area from drainage areas, bank-full conveyance, and percentage of urban development.

Average water levels and average base flow discharge (4.9 cu ft/s) of the Big Sioux River were based on data from 1970 through 1979. The computer model was calibrated for transient conditions by simulating monthly historic conditions for 1976. During 1976, pumpage was offset mostly by surface-water recharge to the aquifer from January through June and ground-water discharge from storage from July through December. Measured drawdowns during 1976 generally were less than 2 feet except in the Sioux Falls city well field where drawdowns were as much as 15 feet. The model was used to study the effects of increased withdrawals under three hypothetical hydrologic situations. One hypothetical situation consisted of using 1976 pumping rates, recharge, and evapotranspiration but the Big Sioux River dry. The pumping rate after 16 months was decreased by 40 percent from the actual pumping rate for that month in order to complete the monthly simulation without the storage being depleted at a nodal area. The second hypothetical situation consisted of a pumpage rate of 44.4 cubic feet per second from 60 wells spaced throughout the aquifer under historic 1976 hydrologic conditions. The results were that the aquifer could supply the additional withdrawal. The third hypothetical situation used the same hydrologic conditions as the second except that recharge was zero and the Big Sioux River was dry downstream from row 54. After 18 monthly simulations, the pumping rate was decreased by 44 percent to prevent pumping wells from depleting the aquifer, and, at that rate, 63 percent of the water being pumped was being replaced by water from the river.

Equations for predicting the magnitude and frequency of floods in the Dallas-Fort Worth metropolitan area were developed from recorded data from streams with drainage areas ranging in size from 1.25 to 66.4 square miles. The U. S. Geological Survey urban rainfall-runoff model was used to generate long-term flood-discharge record for gaged streams in the area. Simulated and recorded annual-peak data were subjected independently to log Pearson III frequency analyses. The results were weighted to determine appropriate discharges for selected 2-, 5-, 10-, 25-, 50-, and 100-year recurrence intervals. These T-year values were then used as the dependent variables in a multiple regression analysis. The independent variable determined to be statistically significant and retained in the resulting equations were drainage area and an urbanization index that expresses the degree of urban development. Analysis of the results shows that a land-use change from rural to fully urbanized is accompanied by a 180% increase in discharge of a flood with a 5-year recurrence interval and about 100% increase in discharge of a flood with a 100-year recurrence interval.

The loss on fusion (LOF) results are comparable to the conventional time-consuming wet-chemical procedure but require no additional effort or cost when conducted as part of the usual sample preparation procedure for quantitative X-ray fluorescence spectrometric analysis (XRF). The technique utilizes the weight loss of the rock when fused with a suitable blend of lithium tetraborate and lithium nitrate. A simple mass balance model is used to represent the thermogravimetric results and to identify the nature of the high temperature mass alteration reactions taking place in the fusion melt. Under the sample preparation conditions used in this study, sulfide appears to be retained quantitatively in the fusion disc sulfate, a phenomenon permitting the determination of sulfide in prepared by a conventional fusion procedure in the form of \r\nrock samples.","language":"ENGLISH","publisher":"U.S. Geological Survey,","doi":"10.3133/ofr82587","usgsCitation":"Mossotti, V., and King, B., 1982, The determination of total volatiles in rocks by loss-on-fusion: U.S. Geological Survey Open-File Report 82-587, 23 p., ill. ;28 cm., https://doi.org/10.3133/ofr82587.","productDescription":"23 p., ill. ;28 cm.","costCenters":[],"links":[{"id":145652,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1982/0587/report-thumb.jpg"},{"id":38278,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1982/0587/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4aa9e4b07f02db6687ee","contributors":{"authors":[{"text":"Mossotti, V.G.","contributorId":43785,"corporation":false,"usgs":true,"family":"Mossotti","given":"V.G.","affiliations":[],"preferred":false,"id":161358,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"King, B.","contributorId":78750,"corporation":false,"usgs":true,"family":"King","given":"B.","affiliations":[],"preferred":false,"id":161359,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}} ,{"id":36564,"text":"fwsobs82_10_22 - 1982 - Habitat Suitability Index Models: Veery","interactions":[],"lastModifiedDate":"2022-02-15T14:36:12.573209","indexId":"fwsobs82_10_22","displayToPublicDate":"1994-01-01T00:00:00","publicationYear":"1982","noYear":false,"publicationType":{"id":18,"text":"Report"},"publicationSubtype":{"id":1,"text":"Federal Government Series"},"seriesTitle":{"id":20,"text":"FWS/OBS","active":false,"publicationSubtype":{"id":1}},"seriesNumber":"82/10.22","subseriesTitle":"Habitat Suitability Index","title":"Habitat Suitability Index Models: Veery","docAbstract":"Habitat preferences and species characteristics of the veery (Catharus fuscesens) are described in this publication.

Guideline for juvenile spot model applications and techniques for estimating model variables are described.","language":"English","publisher":"U.S. Fish and Wildlife Service","usgsCitation":"Stickney, R.R., and Cuenco, M.L., 1982, Habitat Suitability Index Models: Juvenile spot: FWS/OBS 82/10.20, vi, 12 p.","productDescription":"vi, 12 p.","costCenters":[{"id":595,"text":"U.S. Geological Survey","active":false,"usgs":true}],"links":[{"id":165535,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a80e4b07f02db64982d","contributors":{"authors":[{"text":"Stickney, Robert R.","contributorId":93111,"corporation":false,"usgs":true,"family":"Stickney","given":"Robert","email":"","middleInitial":"R.","affiliations":[],"preferred":false,"id":216545,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Cuenco, Michael L.","contributorId":29040,"corporation":false,"usgs":true,"family":"Cuenco","given":"Michael","email":"","middleInitial":"L.","affiliations":[],"preferred":false,"id":216544,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}} ,{"id":36569,"text":"fwsobs82_10_27 - 1982 - Habitat Suitability Index Models: Yellow warbler","interactions":[],"lastModifiedDate":"2022-02-15T14:34:14.639751","indexId":"fwsobs82_10_27","displayToPublicDate":"1994-01-01T00:00:00","publicationYear":"1982","noYear":false,"publicationType":{"id":18,"text":"Report"},"publicationSubtype":{"id":1,"text":"Federal Government Series"},"seriesTitle":{"id":20,"text":"FWS/OBS","active":false,"publicationSubtype":{"id":1}},"seriesNumber":"82/10.27","subseriesTitle":"Habitat Suitability Index","title":"Habitat Suitability Index Models: Yellow warbler","docAbstract":"Habitat preferences of the yellow warbler (Dendroica petechia) are described in this publication. It is one of a series of Habitat Suitability Index (HSI) models and was developed through an analysis of available information on the species-habitat requirements of the species. Habitat use information is presented in a review of the literature, followed by the development of an HSI model, designed for use in impact assessment and habitat management activities.","language":"English","publisher":"U.S. Fish and Wildlife Service","usgsCitation":"Schroeder, R.L., 1982, Habitat Suitability Index Models: Yellow warbler: FWS/OBS 82/10.27, vi, 8 p.","productDescription":"vi, 8 p.","costCenters":[{"id":595,"text":"U.S. Geological Survey","active":false,"usgs":true}],"links":[{"id":165430,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a80e4b07f02db64970d","contributors":{"authors":[{"text":"Schroeder, Richard L.","contributorId":10368,"corporation":false,"usgs":true,"family":"Schroeder","given":"Richard","email":"","middleInitial":"L.","affiliations":[],"preferred":false,"id":216556,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}} ]}
