These include seven sites from the old (~ 2500 m.y.) Precambrian shield of Western Australia, seventeen from the younger (~ 600- 2000 m.y.) Precambrian rocks of South Australia, the Northern Territory, and Queensland, and twenty within the eastern Paleozoic and younger rocks. Thirty of the sites are located where no previous heat-flow data existed, and the remainder provide significant extensions or refinements of areas previously studied. Where the holes studied penetrated the crystalline basement rocks, or where the latter rocks were exposed within a few kilometers of the holes, the upper crustal radiogenic heat production has been estimated based on gamma-ray spectrometric determinations of U, Th, and K abundances. Three heat-flow provinces are recognized in Australia based on the linear relation (q = q* + DA<sub>0</sub> ) between heat flow q and surface radioactivity A<sub>0</sub>. New data from the Western Australian shield support earlier studies showing that heat flow is low to normal with values ranging from 0.7 to 1.2 hfu and with the majority of values less than 1.0 hfu, and the parameters q* = 0.63 hfu and 0 = 4.5 km determined previously were confirmed. Heat flow in the Proterozoic shield of central Australia is quite variable, with values ranging between about l and 3 hfu. This variability is attributed mainly to variations in near-surface crustal radioactivity. The parameters of the heat-flow line are q* = 0.64 hfu and 0 = 11.1 km and moderately high temperatures are predicted for the lower crust and upper mantle. Previous suggestions of a band of l ow- to - normal heat flow near the coast in eastern Australia were confirmed in some areas, but the zone is interrupted in at least one region (the Sydney Basin), where heat flow is about 2.0 hfu over a large area. The reduced heat flow, q*, in the Paleozoic intrusive rocks of eastern Australia varies from about 0.8 to 2.0 hfu . This variability might be related to thermal transients associated with Late Tertiary and younger volcanic and tectonic activity, even though the relation between heat-flow values and the age of volcanism is not a simple one. Parts of the high heat-flow area in the southeast might be exploitable for geothermal energy.</p>","language":"English","publisher":"U.S. Geological

The lakes are: Summit, Upper Trail, and Skilak, all on the Kenai Peninsula, and Eklutna, northeast of Anchorage (fig. 1). Interest in these lakes was stimulated by hypotheses developed from a study of sediments in Van Norman Reservoir, California, after the 1971 San Fernando earthquake (Sims, 1973). During that study three zones of deformational structures were found and correlated with moderate earthquakes that shook the San Fernando area in 1930, 1952, and 1971. Results of that study, coupled with the experimental formation of deformational structures similar to those from Van Norman Reservoir, led to a search for similar structures in Pleistocene and Holocene lakes and lake sediments in other seismically active areas. The lakes for this study were chosen specifically because of their location within the area affected by the 1964 Prince William Sound earthquake, and the probability of obtaining varved sediments which would allow counting of years between sedimentologic events.</p>","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/ofr76373","usgsCitation":"Rymer, M.J., and Sims, J.D., 1976, Preliminary survey of modern glaciolacustrine sediments for earthquake-induced deformational structures, south-central Alaska: U.S. Geological Survey Open-File Report 76-373, 20 p., https://doi.org/10.3133/ofr76373.","productDescription":"20 p.","costCenters":[],"links":[{"id":424897,"rank":2,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1976/0373/report.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":148680,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1976/0373/report-thumb.jpg"}],"country":"United States","state":"Alaska","otherGeospatial":"south-central Alaska","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -152.43345988424275,\n              61.66721907817728\n            ],\n            [\n              -152.43345988424275,\n              59.12721201961355\n            ],\n            [\n              -147.898929065904,\n              59.12721201961355\n            ],\n            [\n              -147.898929065904,\n              61.66721907817728\n            ],\n            [\n              -152.43345988424275,\n              61.66721907817728\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4aabe4b07f02db669957","contributors":{"authors":[{"text":"Rymer, Michael J. mrymer@usgs.gov","contributorId":1522,"corporation":false,"usgs":true,"family":"Rymer","given":"Michael","email":"mrymer@usgs.gov","middleInitial":"J.","affiliations":[{"id":237,"text":"Earthquake Science Center","active":true,"usgs":true}],"preferred":true,"id":171641,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Sims, John D.","contributorId":60202,"corporation":false,"usgs":true,"family":"Sims","given":"John","email":"","middleInitial":"D.","affiliations":[],"preferred":false,"id":171642,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

The program operates on a file of mineral powder diffraction data (VanTrump and Hauff, 1976b) which contains two-theta or 'd' values, and intensities, chemical formula, mineral name, identification number, and mineral group code. XRDPLT is a machine-independent Fortran program which operates in time-sharing mode on a DEC System i0 computer and the Gerber plotter (Evenden, 1974). The program prompts the user to respond from a time-sharing terminal in a conversational format with the required input information. \r\n\r\nThe program offers two major options: retrieval only; retrieval and plot. The first option retrieves mineral names, formulas, and groups from the file by identification number, by the mineral group code (a classification by chemistry or structure), or by searches based on the formula components. For example, it enables the user to search for minerals by major groups (i.e., feldspars, micas, amphiboles, oxides, phosphates, carbonates) by elemental composition (i.e., Fe, Cu, AI, Zn), or by a combination of these (i.e., all copper-bearing arsenates). \r\n\r\nThe second option retrieves as the first, but also plots the retrieved 2-theta and intensity values as diagrammatic X-ray powder patterns on mylar sheets or overlays. These plots can be made using scale combinations compatible with chart recorder diffractograms and 114.59 mm powder camera films. The overlays are then used to separate or sieve out unrelated minerals until unknowns are matched and identified.","language":"ENGLISH","publisher":"U.S. Dept. of the Interior, Geological Survey,","doi":"10.3133/ofr76407","usgsCitation":"Hauff, P.L., and Van Trump, G., 1976, Laboratory manual: mineral X-ray diffraction data retrieval/plot computer program: U.S. Geological Survey Open-File Report 76-407, 55 p. :ill. ;29 cm., https://doi.org/10.3133/ofr76407.","productDescription":"55 p. :ill. ;29 cm.","costCenters":[],"links":[{"id":151300,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1976/0407/report-thumb.jpg"},{"id":48735,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1976/0407/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b27e4b07f02db6b1018","contributors":{"authors":[{"text":"Hauff, Phoebe L.","contributorId":10402,"corporation":false,"usgs":true,"family":"Hauff","given":"Phoebe","email":"","middleInitial":"L.","affiliations":[],"preferred":false,"id":180596,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Van Trump, George","contributorId":19156,"corporation":false,"usgs":true,"family":"Van Trump","given":"George","email":"","affiliations":[],"preferred":false,"id":180597,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

Since the mid-1950 's dissolved oxygen quality has gradually improved owing to low-flow augmentation, the achievement of basinwide secondary treatment, and the use of other waste-management practices. As a result, summer dissolved-oxygen levels have increased, salmon runs have returned, and the overall effort is widely regarded as a singular water-quality success. To document the improved dissolved-oxygen regimen, the U.S. Geological Survey conducted intensive studies of the Willamette during the summer low-flow seasons of 1973 and 1974. During each summer the mean daily dissolved-oxygen levels were found to be higher than 5 milligrams per liter throughout the river. Because of the basinwide secondary treatment, carbonaceous deoxygenation rates were low.

The computed pH generally agreed with observed pH within about a 0.2 pH unit; however, for one 3-week period the computed pH was about a 0.4 unit lower than the observed pH.

Since the mid-1950 's dissolved oxygen quality has gradually improved owing to low-flow augmentation, the achievement of basinwide secondary treatment, and the use of other waste-management practices. As a result, summer dissolved-oxygen levels have increased, salmon runs have returned, and the overall effort is widely regarded as a singular water-quality success. To document the improved dissolved-oxygen regimen, the U.S. Geological Survey conducted intensive studies of the Willamette during the summer low-flow seasons of 1973 and 1974. During each summer the mean daily dissolved-oxygen levels were found to be higher than 5 milligrams per liter throughout the river. Because of the basinwide secondary treatment, carbonaceous deoxygenation rates were low. In addition, almost half of the biochemical oxygen demand entering the Willamette was from diffuse (nonpoint) sources rather than outfalls. These results indicated that point-source biochemical oxygen demand was no longer the primary cause of dissolved-oxygen depletion. Instead, the major causes of deoxygenation were nitrification in a shallow ' surface active ' reach below Salem and an anomalous oxygen demand (believed to be primarily of benthal origin) in Portland Harbor.

The modelled area includes 1,500 square miles (3,885 square kilometres) of the New Jersey Coastal Plain and includes all the important centers of pumping in Monmouth, Burlington, and Ocean Counties from the Wenonah-Mount Laurel aquifer. The Wenonah Formation and Mount Laurel Sand of Late Cretaceous age are exposed in the western part of the New Jersey Coastal Plain along a belt trending northeast-southwest from Raritan Bay to Delaware Bay. The formations typically consist of poorly sorted silty to fine quartz sand, the Wenonah Formation, and a coarse clastic quartz sand unit, the Mount Laurel Sand. The Wenonah-Mount Laurel aquifer is composed of the sandy part of the geologic units. Transmissivity of the aquifer ranges from 360 square feet per day (33.4 square metres per day) to 1,430 square feet per day (132.8 square metres per day); the estimated hydraulic conductivity ranges from about 1.5 x 10<sup>-4</sup> feet per second (4.6 x 10<sup>-5</sup> metres per second) to 2.2 x 10<sup>-4</sup> feet per second (6.7 x 10<sup>-5</sup> metres per second); and the storage coefficient varies from about 1.5 x 10<sup>-5</sup> to 3.5 x 10<sup>-4</sup>. The annual average rate of withdrawal from the Wenonah-Mount Laurel aquifer in Monmouth, Burlington, and Ocean Counties increased from about 1 million gallons per day (44 cubic decimetres per second) in 1959 to slightly more than 2 million gallons per day (88 cubic decimetres per second) in 1970. Near the pumping centers in Monmouth County, the water level declined as much as 100 feet (30.5 metres) between 1959 and 1970. In the subjacent Englishtown aquifer underlying the lower confining unit (Marshalltown Formation), the annual average rate of withdrawal in all of Monmouth and Ocean Counties increased from 5.5 million gallons per day (241 cubic decimetres per second) in 1959 to 9.5 million gallons per day (416 cubic decimetres per second) in 1970. Water-level declines for the same period are as much as 140 feet (42.7 metres) near centers of pumping. The digital-simulation model was calibrated by matching computed declines in the Wenonah-Mount Laurel aquifer with historic water-level declines over the 12-year period, 1959-70. The results of the modelling show that recharge to the aquifer occurs as leakage from the upper confining unit owing to withdrawals from the aquifer. Of equal significance is the effect of water-level declines in the Englishtown aquifer, which generate leakage from the Wenonah-Mount Laurel aquifer through the lower confining unit, which in turn generates leakage (recharge) to the aquifer from the upper confining unit. The rapid declines of water levels in the Wenonah-Mount Laurel aquifer in the northern part of the New Jersey Coastal Plain, hence, are caused directly by the withdrawals from the Wenonah-Mount Laurel aquifer and indirectly by withdrawals from the underlying Englishtown aquifer.","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/ofr75672","collaboration":"Prepared in cooperation with the New Jersey Department of Environmental Protection, Division of Water Resources","usgsCitation":"Nemickas, B., 1976, Digital-simulation model of the Wenonah-Mount Laurel Aquifer in the coastal plain of New Jersey: U.S. Geological Survey Open-File Report 75-672, v, 42 p., https://doi.org/10.3133/ofr75672.","productDescription":"v, 42 p.","numberOfPages":"48","onlineOnly":"Y","additionalOnlineFiles":"N","costCenters":[{"id":470,"text":"New Jersey Water Science Center","active":true,"usgs":true}],"links":[{"id":148999,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/ofr_75_672.gif"},{"id":263361,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1975/672/pdf/ofr75-672.pdf"},{"id":263360,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/of/1975/672/"}],"country":"United States","state":"New Jersey","otherGeospatial":"Wenonah-mount Laurel Aquifer","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -75.0,39.75 ], [ -75.0,40.5 ], [ -73.95,40.5 ], [ -73.95,39.75 ], [ -75.0,39.75 ] ] ] } } ] }","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a82e4b07f02db64ad17","contributors":{"authors":[{"text":"Nemickas, Bronius","contributorId":105733,"corporation":false,"usgs":true,"family":"Nemickas","given":"Bronius","email":"","affiliations":[],"preferred":false,"id":170720,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

The second projection used these same conditions plus a plan of recharging and pumping various areas of the aquifer. The predicted salt balance in 1977 under the proposed plan improved for the Pala, Bonsall, and Mission basins when compared to the predicted 1977 salt balance using 1972 pumpage alone. The plan did not affect the predicted salt balance for the Pauma basin. Under the plan, water levels decreased in the Pala basin and water levels increased in the Bonsall and Mission basins. In addition, an area of potential water logging exists in the Mission basin. The plan did not affect water levels for the Pauma basin.

It was found, for the standard (30 Hz) NCER multiplex system, that subtractive compensation utilizing a 4688 Hz reference signal multiplexed onto each data track was more effective than that utilizing a 3125 Hz reference signal recorded separately on a different track. Moreover, it was found that the portion of the spectrum between the uppermost data channel (3060 Hz + or - 125 Hz) and the compensation reference signal (4688 Hz) could be used to record an additional timing signal, with a center frequency of 3700 Hz and a broader playback bandwidth (ca 0 to 100 Hz) than that of the standard data channels. Accordingly, for the tests described in that report, the standard 8-datachannel multiplex system was augmented by one additional timing channel with a center frequency of 3700 Hz. The 3700 Hz discriminator used in those tests was not successfully set up to utilize subtractive compensation; so its output from a tape playback was quite noisy.\r\n\r\nSubsequently, further tests have been carried out on the application of subtractive compensation to a 4-channel broad-band multiplex system and to the standard multiplex system, both recorded on field tape recorders with relatively poor tape speed control (2), (3). In the course of these experiments, it was discovered that two separate timing channe1s, not just one, can be inserted between the uppermost data channel and the compensation reference signal, Furthermore, it was possible to adjust the discriminators used to playback these timing channels so that they profited significantly from subtractive compensation even though the playback bandwidth was 0 to 100 Hz (for short rise times of square wave timing signals). The advantages of recording two timing signals on each data track include:\r\n\r\n1) one standard time signal to be used for critical timing, e.g. IRIG E, can be recorded with the data on each track, eliminating any problem that might arise from tape head misalignment if the timing base were recorded on a separate track from the data signals being timed,\r\n\r\n2) other essential timing signals e.g. WWVB and IRIG C, can each be recorded on several tracks, to insure more reliable recording through redundancy, without displacing data from standard data channels,\r\n\r\n3) the broader playback bandwidth of the special timing channels reproduces the sharp-edged timing codes with much less distortion than is obtained from the standard data channels.\r\n\r\nIn order to implement subtractive compensation with the 4688 Hz multiplexed signal and to record timing signals on the proposed special timing channels, it was necessary to design and build a signal generator/multiplexer unit. The functions of this unit are:\r\n\r\n1) generate a stable (x-tal controlled) compensation reference frequency (4688 Hz),\r\n\r\n2) generate two timing channel subcarriers (3500 Hz and 3950 Hz) and provide for their modulation by appropriate timing signals,\r\n\r\n3) separately, for each of th~14 tape tracks, adjust the relative levels of the timing and compensation subcarriers and multiplex them, at the appropriate level, with the incoming multiplexed data signals for introduction to the tape system direct record amplifiers. These units will be described in detail by Gray Jensen, who designed and built them, as well as being shown diagrammatically in this report.\r\n\r\nThis report continues the work described in reference (1), and it should be read as a supplement to that report rather than as an independent effort. It introduces changes in the multiplex system and test circuits employed in the tests and then repeats the tests from the earlier report that are required to illustrate the characteristics of the modified system.

The documentation emphasizes the numerical techniques that can be used for solving the simultaneous equations and describes the results of numerical experiments using these techniques. Of the three numerical techniques available in the model, the strongly implicit procedure, in general, requires less computer time and has fewer numerical difficulties than do the iterative alternating direction implicit procedure and line successive overrelaxation (which includes a two-dimensional correction procedure to accelerate convergence). </p><p>The documentation includes a flow chart, program listing, an example simulation, and sections on designing an aquifer model and requirements for data input.

Mex., have been accompanied by slight but progressive increases in the concentration of dissolved solids in water withdrawn from the aquifer. Projected water-level declines through 1996 are estimated from a digital simulation model to not exceed 200 feet (61 metres). A conceptual model of water quality provides three potential sources for water that is relatively high in dissolved solids: brine from the Tularosa Basin to the east, slightly saline water beneath the subjacent aquatard, and very slightly saline water from the less permeable units within the aquifer itself. Management of the well field to minimize drawdown and spread the cone of depression would minimize the rate of water-quality deterioration. A well designed monitoring network may provide advance warning of severe or rapid water-quality deterioration..
