The test well was drilled to determine the feasibility of disposing of liquid waste from the city's secondary treatment plant. Drilling of the test well began in July 1973 and was completed in November 1974. A conventional circulation mud-rotary drilling method was used to a depth of 1,146 feet below land surface and a reverse circulation air-lift method was used to a depth of 3,513 feet. The greatest chloride concentration of water withdrawn from the test well was 31,000 milligrams per liter. The test well, uncased and open to dolomitic limestone between 2,006 and 3,513 feet, yielded 392 gallons per minute with a drawdown of approximately 100 feet.</p>","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/ofr791275","collaboration":"Prepared in cooperation with the City of Sarasota, Florida","usgsCitation":"Sutcliffe, H., 1979, Hydrologic data from a deep test well, City of Sarasota, Florida: U.S. Geological Survey Open-File Report 79-1275, iv, 23 p., https://doi.org/10.3133/ofr791275.","productDescription":"iv, 23 p.","costCenters":[],"links":[{"id":426514,"rank":2,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1979/1275/report.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":143160,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1979/1275/report-thumb.jpg"}],"country":"United States","state":"Florida","city":"Sarasota","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -82.58973838071954,\n              27.407341986046987\n            ],\n            [\n              -82.58973838071954,\n              27.201821801783197\n            ],\n            [\n              -82.36561955593397,\n              27.201821801783197\n            ],\n            [\n              -82.36561955593397,\n              27.407341986046987\n            ],\n            [\n              -82.58973838071954,\n              27.407341986046987\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a1ce4b07f02db607ff0","contributors":{"authors":[{"text":"Sutcliffe, Horace Jr.","contributorId":96725,"corporation":false,"usgs":true,"family":"Sutcliffe","given":"Horace","suffix":"Jr.","email":"","affiliations":[],"preferred":false,"id":163021,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

The network comprises 565 sites, 8 of which will require construction of new wells. Frequencies of sampling at the different sites are assigned at quarterly, semiannual, annual, and 5 years. Selected characteristics of the water will be monitored by both laboratory- and field-analysis methods. The network is designed to: (1) Enable water managers to keep abreast of the general quality of the State 's ground water, and (2) serve as a warning system for undesirable changes in ground-water quality. Data were compiled for hydrogeologic conditions, ground-water quality, cultural elements, and pollution sources. A ' hydrologic unit priority index ' is used to rank 84 hydrologic units (river basins or segments of river basins) of the State for monitoring according to pollution potential. Emphasis for selection of monitoring sites is placed on the 15 highest ranked units. The potential for pollution is greatest in areas of privately owned agricultural land. Other areas of pollution potential are residential development, mining and related processes, and hazardous waste disposal. Data are given for laboratory and field analyses, number of site visits, manpower, subsistence, and mileage, from which costs for implementing the network can be estimated. Suggestions are made for data storage and retrieval and for reporting changes in water quality.&nbsp;</p>","language":"English","publisher":"U.S. Geological

Data were obtained as follows: (1) For sites located at gaging stations, discharges were obtained from Geological Survey and Corps of Engineers annual publications; (2) for sites not too distant from gaging stations, discharges were estimated by using gaging-station records; and (3) for other sites, a series of discharge measurements were made at each site to define a stage-discharge curve from which discharge was computed. Discharges on days of sampling were determined for about 90 of the sites. A tabular summary for the water year 1978 is given. Several discharges for miscellaneous dates in the 1977 water year are shown.

These rocks form a single aquifer system because the formations are hydraulically connected through contact, mine workings, faulting, and fracturing. The aquifer is recharged by precipitation and water moves toward California Gulch and probably toward Evans Gulch, in the drainage basin of the Arkansas River. The Leadville drainage tunnel was constructed from 1943 to 1945 and later extended during 1950 to 1952, in order to drain the mine workings. Discharge from the tunnel lowered water levels 30 to 96 feet in mine shafts from 1944 to 1951. Installation of an impervious plug in the tunnel has been proposed in order to reduce the discharge of water containing objectionable concentrations of trace metals into the East Fork Arkansas River. The proposed plug would reduce the discharge from the tunnel, cause water levels east of the town of Leadville to rise, flood some mine workings, and increase ground-water discharge to California Gulch. However, the proposed plug is not expected to cause water levels in Leadville to rise substantially, but more current and detailed data are needed to verify this. Discharge from the Leadville drainage tunnel is probably a mixture of water in equilibrium with carbonate aquifer materials from the mineralized zone, water acidified by the localized oxidation of pyrite from the mineralized zone, and water nearly saturated with calcite from the glacial mantle. Based on limited data, water from the carbonate mineral deposits has a pH of about 7.0 and concentrations of manganese of about 1,800 micrograms per liter and zinc concentrations of about 13,000 micrograms per liter.

Also included are data for 212 crest-stage and flood profile partial-record stations. Additional water data were collected at various sites not involved in the systematic data-collection program, and are published as miscellaneous measurements.

Data from more than 20 aquifer tests were reanalyzed by the Hantush modified method, which takes into account leakance from all confining units. Transmissivity values range from 20,000 to 240,000 square feet per day. Leakance was estimated to be 2.5x10 to the minus 6th power and 3.3x10 to the minus 5th power per day for the upper and lower confining units, respectively. Families of steady-state distance-drawdown curves were constructed for three representative transmissivity values based on hypothetical withdrawals from a point source ranging from 5 to 50 million gallons per day. Transient effects were not considered because the system reaches steady-state conditions within the time ranges considered. Drawdown at any point can be estimated by summing the effects of any hypothetical configuration of pumping centers. The accuracy of the parameters was checked by comparing calculated drawdowns in selected observation wells to measured water-level declines.

Just 11 Landsat images would encompass the same area mapped to date at a 1:250,000 scale. Navigation satellite data from ground stations can provide the necessary horizontal and vertical ground control in many areas.

A promising approach appears to be the use of Landsat satellite data. In cooperation with the Earth Resources Observation Systems (EROS) Data Center, the commission used machine processing of digital temporal overlays of Landsat data collected in 1972, 1974 and 1976 to detect land use and land cover changes in the Atlanta metropolitan area. Results of the analysis revealed the conversion of forested and open space areas to residential, commercial and industrial land use in the urban-rural fringe zone from 1972 to 1974 and from 1974 to 1976. The study indicated that a land use and land cover change-detection program may be used to revise small-area forecasts of land use, population and employment made by planning models.</p>","language":"English","publisher":"American Institute of Planners","publisherLocation":"Washington, D.C.","usgsCitation":"Todd, W.J., Blackmon, C., and Rudasill, R., 1979, Satellites monitor Atlanta regional development: Practicing Planner, v. 9, no. 1, p. 6-10.","productDescription":"5 p.","startPage":"6","endPage":"10","numberOfPages":"5","costCenters":[{"id":222,"text":"Earth Resources Observation and Science (EROS) Center","active":true,"usgs":true}],"links":[{"id":288574,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"state":"Georgia","city":"Atlanta","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -84.551819,33.647808 ], [ -84.551819,33.887618 ], [ -84.289389,33.887618 ], [ -84.289389,33.647808 ], [ -84.551819,33.647808 ] ] ] } } ] }","volume":"9","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"539acc14e4b0e83db6d08feb","contributors":{"authors":[{"text":"Todd, William J.","contributorId":51595,"corporation":false,"usgs":true,"family":"Todd","given":"William","email":"","middleInitial":"J.","affiliations":[],"preferred":false,"id":494726,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Blackmon, C.C.","contributorId":63321,"corporation":false,"usgs":true,"family":"Blackmon","given":"C.C.","email":"","affiliations":[],"preferred":false,"id":494728,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Rudasill, R.G.

Extensive erosion on the continental slope has occurred primarily during the Tertiary, causing major unconformities and retreat of the shelf edge to its present position. The precise age and number of erosional events is not established, but at least one major erosional event is thought to be Oligocene and related to a marine regression in response to a worldwide eustatic lowering of sea level.</p>\n<br/>\n<p>Velocities derived from the multichannel data reveal distinctive ranges and lateral trends as functions of sediment age, depth of burial, and distance from the coastline. Seismic units beneath the shelf and slope of inferred Tertiary age range from 1.7 to 2.7 km/sec, increasing with age and depth of burial. Units interpreted as Upper Cretaceous rocks beneath the shelf range from 2.3 to 3.6 km/sec and show a distinct lateral increase across the shelf followed by a decrease beneath the present continental slope. Inferred Lower Cretaceous and Upper Jurassic rocks beneath the shelf increase from 3.7 to 4.8 km/sec from nearshore to offshore and indicate a change in facies from clastic units below the inner shelf to carbonate units beneath the outer shelf and upper continental slope. Both reflection and refraction data suggest that thin, high-velocity limestone units (5.0 km/sec) are present within the Lower Cretaceous and Upper Jurassic units beneath the outermost shelf edge, but that these change lithology or pinch out before reaching the middle shelf. Although lateral changes in velocity across the shelf and local velocity inversions appear, the interval velocities along the length of the margin show excellent continuity between Cape Hatteras and Cape Cod. The high-velocity horizons within the Lower Cretaceous and Upper Jurassic shelf-edge complex indicate the presence of a carbonate bank or reef.</p>\n<br/>\n<p>The continental shelf off New Jersey is underlain by a trough approximately 150 km wide with up to 12 km of sedimentary fill. The oceanic basement beneath the upper continental rise is usually at a depth of 10 to 11 km and is overlain by 6 to 8 km of sediments. The rise sediment trough is separated from the shelf trough by an acoustic basement ridge 25 to 75 km wide where penetration never exceeds 6 km beneath sea level, although faulting and carbonate bank or reef complexes frequently limit penetration to 3 to 4 km in this zone. The acoustic basement ridge coincides with the East Coast Magnetic Anomaly and is interpreted as thick oceanic crust formed during the initial phase of seafloor spreading between North America and Africa. Rapid differential subsidence occurred on opposite sides of the basement ridge during the Jurassic and Early Cretaceous. Differential subsidence beneath the shelf also occurred along the margins, with narrower and shallower shelf troughs occurring off platform areas such as Cape Cod and Cape Hatteras.</p>","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"Geological and geophysical investigations of continental margins","language":"English","publisher":"American Association of Petroleum Geologists","publisherLocation":"Tulsa, OK","usgsCitation":"Grow, J.A., Mattick, R.E., and Schlee, J., 1979, Multichannel seismic depth sections and interval velocities over outer continental shelf and upper continental slope between Cape Hatteras and Cape Cod: Rifted margins, chap. <i>of</i> Geological and geophysical investigations of continental margins, p. 65-83.","productDescription":"19 p.","startPage":"65","endPage":"83","costCenters":[{"id":186,"text":"Coastal and Marine Geology Program","active":true,"usgs":true},{"id":678,"text":"Woods Hole Coastal and Marine Science Center","active":true,"usgs":true}],"links":[{"id":295747,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":295743,"type":{"id":15,"text":"Index Page"},"url":"https://archives.datapages.com/data/specpubs/history2/data/a109/a109/0001/0050/0065.htm"}],"country":"United States","otherGeospatial":"Cape Cod, Cape Hatteras","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -77.4041748046875,\n              34.49750272138159\n            ],\n            [\n              -75.091552734375,\n              34.49750272138159\n            ],\n            [\n              -75.091552734375,\n              36.097938036628065\n            ],\n            [\n              -77.4041748046875,\n              36.097938036628065\n            ],\n            [\n              -77.4041748046875,\n              34.49750272138159\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"544b6a2be4b03653c63fb1db","contributors":{"authors":[{"text":"Grow, John A.","contributorId":41763,"corporation":false,"usgs":true,"family":"Grow","given":"John","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":503949,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Mattick, Robert E.","contributorId":50462,"corporation":false,"usgs":true,"family":"Mattick","given":"Robert","email":"","middleInitial":"E.","affiliations":[],"preferred":false,"id":503950,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Schlee, John S.","contributorId":99912,"corporation":false,"usgs":true,"family":"Schlee","given":"John S.","affiliations":[{"id":678,"text":"Woods Hole Coastal and Marine Science Center","active":true,"usgs":true}],"preferred":false,"id":503951,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

This numerical model is patterned after an existing algorithm and has been carefully tested in rectangular and curve-sided channels with constant and variable depth. One of the common uncertainties in this class of two-dimensional hydrodynamic models is the treatment of the lateral boundary conditions. Special attention is paid specifically to addressing this problem. To maintain continuity within the domain of interest, &lsquo;smooth&rsquo; curve-sided elements must be used at all shoreline boundaries. The present model uses triangular, isoparametric elements with quadratic basis functions for the two velocity components and a linear basis function for water surface elevation. An implicit time integration is used and the model is unconditionally stable. The resultant governing equations are nonlinear owing to the advective and the bottom friction terms and are solved iteratively at each time step by the Newton-Raphson method. Model test runs have been made in the southern portion of San Francisco Bay, California (South Bay) as well as in the Bay west of Carquinez Strait. Owing to the complex bathymetry, the hydrodynamic characteristics of the Bay system are dictated by the generally shallow basins which contain deep, relict river channels. Great care must be exercised to ensure that the conservation equations remain locally as well as globally accurate. Simulations have been made over several representative tidal cycles using this finite element model, and the results compare favourably with existing data. In particular, the standing wave in South Bay and the progressive wave in the northern reach are well represented.</span></p>","language":"English","publisher":"Elsevier","doi":"10.1016/0309-1708(79)90033-2","usgsCitation":"Walters, R.A., and Cheng, R.T., 1979, A two-dimensional hydrodynamic model of a tidal estuary: Advances in Water Resources, v. 2, p. 177-184, https://doi.org/10.1016/0309-1708(79)90033-2.","productDescription":"8 p.","startPage":"177","endPage":"184","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[{"id":552,"text":"San Francisco Bay-Delta","active":false,"usgs":true},{"id":5079,"text":"Pacific Regional Director's Office","active":true,"usgs":true}],"links":[{"id":325192,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"California","otherGeospatial":"San Francisco Bay","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -122.61291503906249,\n              37.385435182627226\n            ],\n            [\n              -122.61291503906249,\n              38.23170796744926\n            ],\n            [\n              -121.61865234375,\n              38.23170796744926\n            ],\n            [\n              -121.61865234375,\n              37.385435182627226\n            ],\n            [\n              -122.61291503906249,\n              37.385435182627226\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5787662ce4b0d27deb36e16f","contributors":{"authors":[{"text":"Walters, Roy A.","contributorId":74877,"corporation":false,"usgs":true,"family":"Walters","given":"Roy","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":642384,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Cheng, Ralph T.","contributorId":69134,"corporation":false,"usgs":true,"family":"Cheng","given":"Ralph","email":"","middleInitial":"T.","affiliations":[],"preferred":false,"id":642385,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

Sixteen nets are located along the San Andreas fault system between Point Reyes, California, and the United States‐Mexico border. Other locations are across the Garlock fault in California; across Puget Sound near Seattle, Washington; near Hanford in eastern Washington; near Hebgen Lake in Montana; across the Wasatch fault at Ogden, Utah; across the Rio Grande rift at Socorro, New Mexico; and Dixie Valley in Nevada; and at the northern end of Owens Valley on the California‐Nevada border. Implicit in the treatment are the assumptions that the strain was accumulating at a constant rate over the time period (within the interval 1970–1978) and over the local area (usually about 50‐km diameter) covered by the surveys. Of the nets located away from the San Andreas fault, only Ogden and Hebgen show significant strain accumulation. At Ogden the deformation is principally an east‐west compression of 0.23±0.05 μstrain/yr and at Hebgen Lake a northeast‐southwest extension of 0.17±0.03 μstrain/yr. Along the San Andreas fault system the rate of shear is 0.2 to 0.4μ/yr. The direction of shear agrees very well with the surface strike of nearby faults. This agreement is maintained even in regions like the ‘big bend,’ where both the fault strike and the observed shear direction are more westerly than they are elsewhere. Shear strain in northern California appears to be concentrated more closely on the faults, whereas in southern California the strain is a broader, smoother feature. In the San Francisco Bay area the strain data indicate slip at depth on both the San Andreas and the Calaveras faults. In addition to the observed shear the nets in California indicate a negative dilatation (areal decrease) of about 0.2 μstrain/yr. This dilatation is unexplained, but the following sources appear unlikely: (1) systematic survey error, (2) an association with the southern California uplift, (3) an association with the big bend in the San Andreas fault in Southern California, or (4) the result of the superposition of a uniaxial strain on the Pacific‐North American plate boundary shear.</span></p>","language":"English","publisher":"American Geophysical Union","doi":"10.1029/JB084iB10p05423","usgsCitation":"Prescott, W., Savage, J.C., and Kinoshita, W.T., 1979, Strain accumulation rates in the western United States between 1970 and 1978: Journal of Geophysical Research B: Solid Earth, v. 84, no.

Quite often the importance of the data processing phase of a current-measurement program is underestimated and downplayed. In this paper a data-processing system which performs the complete data processing and analyses is described. The system, which is configured around an LSI-11 microcomputer, has been assembled to provide the capabilities of data translation, reduction, and tabulation and graphical display immediately following recovery of current meters. The flexibility inherent in a microcomputer has made it available to perform many other research functions which would normally be done on an institutional computer.</span></p>","largerWorkType":{"id":24,"text":"Conference Paper"},"largerWorkTitle":"Proceedings of Oceans","conferenceTitle":"Oceans '79","conferenceDate":"17-19 Sept. 1979","conferenceLocation":"San Diego, CA","language":"English","publisher":"IEEE","doi":"10.1109/OCEANS.1979.1151234","usgsCitation":"Cheng, R.T., and Gartner, J.W., 1979, A microcomputer based system for current-meter data acquisition, <i>in</i> Proceedings of Oceans, San Diego, CA, 17-19 Sept. 1979, p. 288-291, https://doi.org/10.1109/OCEANS.1979.1151234.","productDescription":"4 p.","startPage":"288","endPage":"291","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[{"id":552,"text":"San Francisco Bay-Delta","active":false,"usgs":true},{"id":5079,"text":"Pacific Regional Director's Office","active":true,"usgs":true}],"links":[{"id":325673,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"579889aee4b0589fa1c6b9f5","contributors":{"authors":[{"text":"Cheng, R.

Properties of firm exploration behavior are obscured when highly aggregated data are used. Data pertaining to different geographical areas are frequently combined using dummy variables to denote characteristics peculiar to a region. In these models price tends to be more related to the quality of the crude oil than to incremental costs of exploration and development of individual deposits. The effect of price changes on expected supplies is clearly moderated by the level of resource depletion for a particular basin. A major obstacle to carrying out a less aggregated analysis has been the lack of data on specific basins, but another obstacle has been the belief that field behavior is too erratic to model successful.</p>","language":"English","publisher":"University of Wisconsin Press","doi":"10.2307/3145904","usgsCitation":"Attanasi, E., 1979, Nature of firm expectations in petroleum exploration: Land Economics, v. 55, no. 3, p. 299-312, https://doi.org/10.2307/3145904.","productDescription":"14 p.","startPage":"299","endPage":"312","costCenters":[{"id":241,"text":"Eastern Energy Resources Science Center","active":true,"usgs":true}],"links":[{"id":357490,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"55","issue":"3","noUsgsAuthors":false,"publicationStatus":"PW","contributors":{"authors":[{"text":"Attanasi, Emil D. 0000-0001-6845-7160 attanasi@usgs.gov","orcid":"https://orcid.org/0000-0001-6845-7160","contributorId":198728,"corporation":false,"usgs":true,"family":"Attanasi","given":"Emil D.","email":"attanasi@usgs.gov","affiliations":[{"id":241,"text":"Eastern Energy Resources Science Center","active":true,"usgs":true}],"preferred":true,"id":745575,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}
