Fat indices were highest in March arrivals, generally declined throughout the summer, and were lowest in September.  In both 1972 and 1973 bats had arrived at the study area by mid-March.  In 1971 bats were last noted at the area in mid-October while in 1972 they had disappeared by late September.  On the basis on physiological calculations it is estimated that bats collected in March 1972 possessed sufficient fat reserves to carry them a mean distance of 716 km north of the study area while September bats had only enough reserves to fly 386 km southward, about 160 km short of the nearest known Sonora wintering locality.  It is suggested that in spring the bats may have a more rigidly timed migration and so put on excess fat to counter an uncertain environment to the north.  The fall migration may be triggered by more unpredictable events, such as the passage of cold fronts, and less fat reserves may be required for movements into more favorable southern locales.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Southwestern Naturalist","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Southwestern Association of Naturalists","publisherLocation":"Dallas, TX","doi":"10.2307/3669717","usgsCitation":"O'Shea, T., 1976, Fat content in migratory central Arizona Brazilian free-tailed bats, <i>Tadarida brasiliensis</i> (Molossidae): Southwestern Naturalist, v. 21, no. 3, p. 321-326, https://doi.org/10.2307/3669717.","productDescription":"6 p.","startPage":"321","endPage":"326","numberOfPages":"6","costCenters":[],"links":[{"id":291848,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":291847,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.2307/3669717"}],"country":"United States","state":"Arizona","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -114.8166,31.3322 ], [ -114.8166,37.0043 ], [ -109.0452,37.0043 ], [ -109.0452,31.3322 ], [ -114.8166,31.3322 ] ] ] } } ] }","volume":"21","issue":"3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"53e492cbe4b0fff40428a573","contributors":{"authors":[{"text":"O'Shea, Thomas J. 0000-0002-0758-9730","orcid":"https://orcid.org/0000-0002-0758-9730","contributorId":78071,"corporation":false,"usgs":true,"family":"O'Shea","given":"Thomas J.","affiliations":[{"id":291,"text":"Fort Collins Science Center","active":true,"usgs":true}],"preferred":false,"id":497721,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

During this time interval compressive strains were oriented roughly normal to the San Andreas fault, suggesting that the uplift produced little shear strain accumulation across this fault. On the other hand, the orientation of the anomalous shear straining is consistent with strain accumulation across northdipping range-front thrusts like the San Fernando fault. Accordingly, the horizontal and vertical crustal deformation disclosed by geodetic observation is interpreted as a short epoch of rapid strain accumulation on these frontal faults. If this interpretation is correct, thrust-type earthquakes will eventually release the accumulated strains, but the geodetic data examined here cannot be used to estimate when these events might occur. However, observation of an unusual sequence of tilts prior to 1971 on a level line lying to the north of the magnitude 6.4 San Fernando earthquake offers some promise for precursor monitoring. The data are adequately explained by a simple model of up-dip aseismic slip propagation toward the 1971 epicentral region. These observations and the simple model that accounts for them suggest a conceptually straightforward monitoring scheme to search for similar uplift and tilt precursors within the uplifted region. Such premonitory effects could be detected by a combination of frequently repeated short (30 to 70 km in length) level line measurements, precise gravity traverses, and continuously recording gravimeters sited to the north of the active frontal thrust faults. Once identified, such precursors could be closely followed in space and time, and might then provide effective warnings of impending potentially destructive earthquakes.</span></p>","language":"English","publisher":"American Association for the Advancement of Science","doi":"10.1126/science.194.4266.691","issn":"00368075","usgsCitation":"Thatcher, W., 1976, Episodic strain accumulation in Southern California: Science, v. 194, no. 4266, p. 691-695, https://doi.org/10.1126/science.194.4266.691.","productDescription":"5 p.","startPage":"691","endPage":"695","costCenters":[],"links":[{"id":221024,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"California","otherGeospatial":"Southern California","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -121.9804029819224,\n              36.30513645238112\n            ],\n            [\n              -120.96601429202806,\n              34.360346703747\n            ],\n            [\n              -119.17331019306403,\n              32.27556539094205\n            ],\n            [\n              -114.34970515576546,\n              32.86548144988561\n            ],\n            [\n              -114.08039140095518,\n              34.30260170922787\n            ],\n            [\n              -114.596289953596,\n              34.95052476022777\n            ],\n            [\n              -117.75432473596952,\n              37.47447472393604\n            ],\n            [\n              -121.9804029819224,\n              36.30513645238112\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","volume":"194","issue":"4266","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a0a15e4b0c8380cd521c3","contributors":{"authors":[{"text":"Thatcher, W.","contributorId":32669,"corporation":false,"usgs":true,"family":"Thatcher","given":"W.","email":"","affiliations":[],"preferred":false,"id":360421,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

After 10 months in the field, two Beckman-Whitley total hemispherical radiometers and one Eppley pyranometer were recalibrated by using the shading technique. The working standard was an Eppley pyrheliometer. Errors as great as 38 percent were discovered. New calibration constants were determined for all three field instruments. The shading technique is a rapid, accurate method of recalibrating under field conditions.

Heat flux in this range characterizes the postvolcanic environment on Surtsey in which the subaerial palagonitization of basaltic tephra is associated with mass transfer of hydrothermal vapor, either of meteoric or sea-water origin, only a few years after cessation of eruptive activity. The flux estimation is the result of the Surtsey data-relay experiment via Landsat-1 which was carried. out in several phases. Successful field installation and test transmissions demonstrated the feasibility of repetitive long-distance (that is, 4,800-km) data transmission and reception from a volcanic environment in Iceland via the Landsat Data Collection System. Temperature data were transmitted for a 38-day period in November and December 1972. A near-surface vertical gradient of 69.4 °C/m was obtained, suggesting a mixed mechanism of heat transfer, partitioned between conduction and convection. Comparison of four methods for estimating fluxes between 500 and 1,500 <i><span>μ</span></i>cal cm<sup>-2</sup>s<sup>-1</sup>, using temperature data derived from the Data Collection Platform, suggests that, where the only temperature available are from the surface and a depth of 1 m, methods of estimating the net geothermal flux from examination of spectral radiance are superior to methods that assume dominant convection or conduction. A computerized thermal-modeling technique to construct parametric diurnal surface-temperature curves is particularly applicable. Flux-estimation methods that assume dominant convection or conduction are limited by the lack of temperature data at greater depths and lack of knowledge of the exact energy partition.</p>","language":"English","publisher":"U.S. Geological Survey","usgsCitation":"Friedman, J., Preble, D.M., and Jakobsson, S.P., 1976, Geothermal flux through palagonitized tephra, Surtsey, Iceland: The Surtsey temperature-data-relay experiment via Landsat-1: Journal of Research of the U.S. Geological Survey, v. 4, no. 6, p. 645-659.","productDescription":"15 p.","startPage":"645","endPage":"659","costCenters":[],"links":[{"id":404122,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":404121,"rank":1,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/journal/1976/vol4issue6/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"country":"Iceland","otherGeospatial":"Surtsey","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -20.622711181640625,\n              63.295099351960246\n            ],\n            [\n              -20.58614730834961,\n              63.295099351960246\n            ],\n            [\n              -20.58614730834961,\n              63.313685020999294\n            ],\n            [\n              -20.622711181640625,\n              63.313685020999294\n            ],\n            [\n              -20.622711181640625,\n              63.295099351960246\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"4","issue":"6","noUsgsAuthors":false,"publicationStatus":"PW","contributors":{"authors":[{"text":"Friedman, Jules D.","contributorId":76757,"corporation":false,"usgs":true,"family":"Friedman","given":"Jules D.","affiliations":[],"preferred":false,"id":847081,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Preble, Duane M.","contributorId":36560,"corporation":false,"usgs":true,"family":"Preble","given":"Duane","email":"","middleInitial":"M.","affiliations":[],"preferred":false,"id":847082,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Jakobsson, Sveinn P.","contributorId":40121,"corporation":false,"usgs":true,"family":"Jakobsson","given":"Sveinn","email":"","middleInitial":"P.","affiliations":[],"preferred":false,"id":847083,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

During deposition of the Jackson Group, conditions were similar to those existing along the modern Gulf Coast of Texas except for a less arid climate and a greater supply of volcanic sediment. Sedimentary depositional environments recognized in both the modern coast and the Jackson rocks, in order from sea toward land, are: shoreface, beach, lagoon and bay, and paludal. Sediment deposited in these environments in places is interbedded with or transected by fluvial sediment. Both uranium and petroleum are found in the shoreface, beach, and fluvial facies. These facies are characterized by permeable well-sorted sandstone, which is commonly overlain and underlain by less permeable mudstone. A typical vertical sequence in ascending order through a unit containing a beach sandstone facies is (1) lagoonal or paludal clay stone and siltstone, (2) crossbedded fine-grained beach sandstone which contains <i>Ophiomorpha</i> burrows and, which, in places, is locally interbedded with lacustrine or lagoonal mudstone, (3) weakly laminated beach sandstone which contains root impressions at the top and <i>Ophiomorpha</i>, and (4) lagoonal or paludal claystone and siltstone. Gulfward, the beach sandstone apparently grades into highly burrowed, generally finer grained, more poorly sorted, less porous shoreface rocks. The beach facies may include barrier island beaches and mainland beaches, some of which were probably cheniers. Beach facies sandstone units extend many miles along the depositional strike, which nearly parallels the present outcrop strike, but extend only a mile or two (2-3 km) normal to the depositional strike into the subsurface. Recognition of the various facies in outcrops and drill holes is necessary for determination of true stratigraphic relations and for aid in exploration for beach and fluvial sandstone favorable for uranium and petroleum accumulations.</p>","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","usgsCitation":"Dickinson, K.A., 1976, Sedimentary depositional environments of uranium and petroleum host rocks of the Jackson Group, south Texas: Journal of Research of the U.S. Geological Survey, v. 4, no. 5, p. 615-629.","productDescription":"15 p.","startPage":"615","endPage":"629","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[],"links":[{"id":307454,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":307453,"rank":1,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/journal/1976/vol4issue5/report.pdf","text":"Report","size":"29.18 MB","linkFileType":{"id":1,"text":"pdf"},"description":"Report"}],"country":"United States","state":"Texas","county":"Karnes County, McMullen County, Duval County","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -100,\n              31.541089879585808\n            ],\n            [\n              -94,\n              31.541089879585808\n            ],\n            [\n              -94,\n              29.649868677972304\n            ],\n            [\n              -94.482421875,\n              29.401319510041485\n            ],\n            [\n              -95.361328125,\n              28.844673680771795\n            ],\n            [\n              -96.240234375,\n              28.478348692223165\n            ],\n            [\n              -96.65771484375,\n              28.07198030177986\n            ],\n            [\n              -97.119140625,\n              27.254629577800088\n            ],\n            [\n              -97.22900390625,\n              26.43122806450644\n            ],\n            [\n              -96.9873046875,\n              25.859223554761407\n            ],\n            [\n              -97.42675781249999,\n              25.859223554761407\n            ],\n            [\n              -98.19580078125,\n              26.03704188651584\n            ],\n            [\n              -99.03076171875,\n              26.2145910237943\n            ],\n            [\n              -99.5361328125,\n              27.00040800352175\n            ],\n            [\n              -99.64599609375,\n              27.625140335093324\n            ],\n            [\n              -100,\n              28.130127737874005\n            ],\n            [\n              -100,\n              31.541089879585808\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"4","issue":"5","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"55dd91bee4b0518e354dd1b9","contributors":{"authors":[{"text":"Dickinson, Kendell A.","contributorId":55430,"corporation":false,"usgs":true,"family":"Dickinson","given":"Kendell","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":569861,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

Records of 20 gaged basins in the Delmarva Peninsula of Maryland, Delaware, and Virginia were analyzed for 40 statistical streamflow characteristics. Equations relating these characteristics to basin characteristics were obtained by a technique of multiple linear regression. A control group of equations contains basin characteristics derived from maps. An experimental group of equations contains basin characteristics derived from maps and imagery. Characteristics from imagery were forest, riparian (streambank) vegetation, water, and combined agricultural and urban land use. These basin characteristics were isolated photographically by techniques of film-density discrimination. The area of each characteristic in each basin was measured photometrically. Comparison of equations in the control group with corresponding equations in the experimental group reveals that for 12 out of 40 equations the standard error of estimate was reduced by more than 10 percent. As an example, the standard error of estimate of the equation for the 5-year recurrence-interval flood peak was reduced from 46 to 32 percent. Similarly, the standard error of the equation for the mean monthly flow for September was reduced from 32 to 24 percent, the standard error for the 7-day, 2-year recurrence low flow was reduced from 136 to 102 percent, and the standard error for the 3-day, 2-year flood volume was reduced from 30 to 12 percent. It is concluded that data from Landsat imagery can substantially improve the accuracy of estimates of some streamflow characteristics at sites in the Delmarva Peninsula.</p>","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","usgsCitation":"Hollyday, E.F., 1976, Improving estimates of streamflow characteristics by using Landsat-1 imagery: Journal of Research of the U.S. Geological Survey, v. 4, no. 5, p. 517-531.","productDescription":"15 p.","startPage":"517","endPage":"531","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[],"links":[{"id":307396,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":307395,"rank":1,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/journal/1976/vol4issue5/report.pdf","text":"Report","size":"29.18 MB","linkFileType":{"id":1,"text":"pdf"},"description":"Report"}],"country":"United States","state":"Maryland, Delaware, Virginia","otherGeospatial":"Delmarva Peninsula","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -77,\n              37.5\n            ],\n            [\n              -77,\n              40\n            ],\n            [\n              -74,\n              40\n            ],\n            [\n              -74,\n              37.5\n            ],\n            [\n              -77,\n              37.5\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"4","issue":"5","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"55dd91b7e4b0518e354dd17d","contributors":{"authors":[{"text":"Hollyday, Este F.","contributorId":27089,"corporation":false,"usgs":true,"family":"Hollyday","given":"Este","email":"","middleInitial":"F.","affiliations":[],"preferred":false,"id":569707,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

An uppermost lens of freshwater, which occupies relatively permeable glacial-outwash sand and gravel to a depth of 520 feet (158 metres), is believed to be in hydrodynamic equilibrium with the present level of the sea and the height of the water table. However, two zones of freshwater at 730 to 820 ft (222-249 m) and 900 to 930 ft (274-283 m) are anomalously deep. Although several explanations are possible, the most likely is that the entire surface of the Continental Shelf was exposed to recharge by precipitation during long periods of low sea level in Pleistocene time. After the last retreat of glacial ice, seawater rapidly drowned the shelf around Nantucket Island. Since then, about 8,000 years ago, the deep freshwater zones which underlie dense clay layers have not had time to adjust to a new equilibrium. Under similar circumstances, freshwater may remain trapped under extensive areas of the Continental Shelf wherever clay confining beds have not permitted saltwater to intrude rapidly to new hydrodynamic equilibria positions. The implications are far reaching because all continental shelves worldwide were exposed to similar hydrologic influences during Pleistocene time.</p>","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","usgsCitation":"Kohout, F., Walker, E., Bothner, M., and Hathaway, J., 1976, Fresh ground water found deep beneath Nantucket Island, Masachusetts: Journal of Research of the U.S. Geological Survey, v. 4, no. 5, p. 511-515.","productDescription":"5 p.","startPage":"511","endPage":"515","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[],"links":[{"id":307391,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":307390,"rank":1,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/journal/1976/vol4issue5/report.pdf#page=11","size":"29.18 MB","linkFileType":{"id":1,"text":"pdf"},"description":"Report"}],"country":"United States","state":"Massachusetts","otherGeospatial":"Nantucket Island","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -71.2,\n              41\n            ],\n            [\n              -71.2,\n              43\n            ],\n            [\n              -69.5,\n              43\n            ],\n            [\n              -69.5,\n              41\n            ],\n            [\n              -71.2,\n              41\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"4","issue":"5","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"55dd91b4e4b0518e354dd16d","contributors":{"authors":[{"text":"Kohout, F.

The balsam-mounted thin sections were removed from the glass slides by soaking them in methylene chloride. The freed sections were mixed with twice their weight of Li<sub>2</sub>B<sub>4</sub>O<sub>7</sub>, and fused at 1100&deg; C. A fragment of the resulting glasslike bead was mounted for probe analysis. Both wavelength and energy-dispersive detector systems were used for quantitative determinations of elements sodium through iron. Because the samples and standards are diluted and fused, powdered rock standards may be used as reference materials. The calibration curves obtained by plotting X-ray intensity versus concentration of the analyte are linear over the concentration ranges used in this work and have an overall range of error of 2 to 8 percent. Although some of the analytical values show excessive scatter for petrographically similar rocks, in general the analyses are acceptable given the sample size and analytical uncertainties. Bulk chemical analyses were made of 18 thin sections, including altered diabase, amphibolite, and calc-silicate hornfels produced by progressive contact metamorphism and associated with metasomatic magnetite deposits in the Samli area, western Turkey. Normative plots indicate that (1) diabase and amphibolite are compositionally related and are similar to average compositions of basalts and orthoamphibolites, and (2) calc-silicate hornfels appears to have been derived in part from amphibolite and in part from crystalline limestone that underlies much of the region.</p>","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","usgsCitation":"Lindsay, J.R., and Leo, G.W., 1976, Bulk chemical analyses of petrographic thin sections of rocks of the Samli area, western Turkey: Journal of Research of the U.S. Geological Survey, v. 4, no. 5, p. 569-574.","productDescription":"6 p.","startPage":"569","endPage":"574","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[],"links":[{"id":307418,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":307417,"rank":1,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/journal/1976/vol4issue5/report.pdf","text":"Report","size":"29.18 MB","linkFileType":{"id":1,"text":"pdf"},"description":"Report"}],"country":"Turkey","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              26,\n              39\n            ],\n            [\n              26,\n              42\n            ],\n            [\n              30,\n              42\n            ],\n            [\n              30,\n              39\n            ],\n            [\n              26,\n              39\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"4","issue":"5","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"55dd91aee4b0518e354dd132","contributors":{"authors":[{"text":"Lindsay, James R.","contributorId":19714,"corporation":false,"usgs":true,"family":"Lindsay","given":"James","email":"","middleInitial":"R.","affiliations":[],"preferred":false,"id":569769,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Leo, Gerhard W.","contributorId":26307,"corporation":false,"usgs":true,"family":"Leo","given":"Gerhard","email":"","middleInitial":"W.","affiliations":[],"preferred":false,"id":569770,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}
