Treated sweage that had a mean chloride concentration of 170 milligrams per liter (mg/l) was injected through a single well for 12 months at a mean rate of 4. 7 multiplied by 10**5 cubic feet per day (ft**3/d). The volume of water injected during the year was 1. 7 multiplied by 10**8 cubic feet. Pressure buildup at the end of one year ranged from less than 0. 1 to as much as 2. 4 pounds per square inch (lb/in**2) in observation wells at the site. Pressure buildup in wells open to the upper part of the injection zone was related to buoyant lift acting on the mixed water in the injection zone in addition to subsurface injection through the injection well. Calculations of the vertical component of pore velocity in the semiconfining bed underlying the shallowest permeable zone of the Floridan aquifer indicate upward movement of native water.","language":"English","publisher":"Wiley","doi":"10.1111/j.1745-6584.1984.tb01475.x","issn":"0017467X","usgsCitation":"Hickey, J., 1984, Subsurface injection of treated sewage into a saline-water aquifer at St. Petersburg, Florida - Aquifer pressure buildup: Ground Water, v. 22, no. 1, p. 48-55, https://doi.org/10.1111/j.1745-6584.1984.tb01475.x.","productDescription":"8 p.","startPage":"48","endPage":"55","numberOfPages":"8","costCenters":[{"id":589,"text":"Toxic Substances Hydrology Program","active":true,"usgs":true}],"links":[{"id":226124,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Florida","city":"St. Petersburg","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -82.880859375,\n              27.444915505146934\n            ],\n            [\n              -82.254638671875,\n              27.444915505146934\n            ],\n            [\n              -82.254638671875,\n              28.057438520876673\n            ],\n            [\n              -82.880859375,\n              28.057438520876673\n            ],\n            [\n              -82.880859375,\n              27.444915505146934\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"22","issue":"1","noUsgsAuthors":false,"publicationDate":"2006-03-21","publicationStatus":"PW","scienceBaseUri":"505b9d7ae4b08c986b31d895","contributors":{"authors":[{"text":"Hickey, J.J.","contributorId":57010,"corporation":false,"usgs":true,"family":"Hickey","given":"J.J.","email":"","affiliations":[],"preferred":false,"id":367281,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

A comparison of the source characteristics of two different-sized water guns with those of conventional air guns shows the the water gun signature is cleaner and much shorter than that of a comparable-sized air gun: about 60-100 milliseconds (ms) for an 80-in3. (1.31-liter (I)) water gun compared with several hundred ms for an 80-in3. (1.31-1) air gun. The source spectra of water guns are richer in high frequencies (>200 Hz) than are those of air guns, but they also have less energy than those of air guns at low frequencies. A comparison between water gun and air gun reflection profiles in both shallow (Long Island Sound)-and deep (western Bermuda Rise)-water settings suggests that the water gun offers a good compromise between very high resolution, limited penetration systems (e.g. 3.5-kHz profilers and sparkers) and the large volume air guns and tuned air gun arrays generally used where significant penetration is required. ?? 1984 D.

Six streamflow gain-and-loss investigations, conducted in 1982 along a 25.8 mi reach of the South Platte River, indicate an average downstream gain in discharge of 150 cu ft/sec during the irrigation season. The Fort Morgan Canal and the Lower Platte and Beaver Canal had decreasing discharges in the downstream direction. The Upper Platte and Beaver Canal had a slight increased in discharge at the second measurement site and decreases in the third and fourth measurement sites. Irrigation practices and some loss to the groundwater system account for the general decrease in discharge. Suspended sediment data were collected at the streamflow-gaging station 06758500 South Platte River near Weldona and on the three irrigation canals: Fort Morgan Canal, Upper Platte and Beaver Canal, and Lower Platte and Beaver Canal. The data indicate that relations exist between the suspended sediment concentrations at the South Platte River station and the suspended sediment concentrations at the most upstream measurement site on each canal. Relations between suspended sediment discharge and water discharge were developed at all canal measurement sites. For all the canals, suspended sediment discharge decreased in a downstream direction. Slight increases in suspended sediment occurred at the second measurement site on the Upper Platte and Beaver Canal and at the third measurement site on the Lower Platte and Beaver Canal.

The 1:100,000-scale USGS map series was designed to facilitate automated data capture.

For both 1 and 4 years post-spray, vegetation development was greater in the third height interval (> 3.0 m) on untreated sites. All measures of vegetative diversity on untreated sites exceeded those on treated sites. Overall density and diversity of birds were similar between treated and untreated sites. Several bird species altered their foraging behavior on treated sites, i.e., birds using deciduous trees increased use of shrubs on treated sites. The primary effect of herbicide application was a reduction in the complexity of vegetation, a condition due primarity to the removal of deciduous trees. Small patches of deciduous trees scattered in clear-cuts treated with phenoxy herbicides can maintain an avian community similar to that on untreated sites.","language":"English","publisher":"Wiley","doi":"10.2307/3808449","usgsCitation":"Morrison, M.L., and Meslow, E.C., 1984, Response of avian communities to herbicide-induced vegetation changes:

Sandstone beds are the principal aquifers for domestic supply and livestock watering, with the Knobloch coal bed being a secondary source of supply. Surface-water resources consist principally of perennial flow in Otter Creek and intermittent flow in eight small drainage basins. The small streams are generally dry at their mouth, except after intense rainfall or sudden snowmelt. Otter Creek is used for livestock watering and, during spring floods, for irrigating alfalfa fields. The water supplied by wells generally is a sodium bicarbonate type. Dissolved-solids concentrations of water samples ranged from 480 to 3,460 milligrams per liter in sandstone beds and from 910 to 6,260 milligrams per liter in the Knobloch coal bed. Water in Otter Creek contains principally sodium, magnesium, and sulfate ions. The dissolved-solids concentration ranged from 2,050 to 2 ,950 milligrams per liter. Mining of the Knobloch coal bed would remove three private wells and adversely affect the yield of two other wells. After mining, water in the alluvium of Otter Creek might show long-term degradation in water quality as a result of waters leaching the soluble salts from the spoils material used to backfill the mine pits. Although mining would alter the existing hydrologic systems and remove several shallow wells, alternative ground-water supplies are available from deeper aquifers that could be developed to replace those lost by mining.</p>","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/wri844087","usgsCitation":"McClymonds, N.E., 1984, Potential effects of surface coal mining on the hydrology of the West Otter area, Ashland and Birney-Broadus coal fields, southeastern Montana: U.S. Geological Survey Water-Resources Investigations Report 84-4087, Report: vi, 70 p.; 1 Plate: 16.58 x 24.21 inches, https://doi.org/10.3133/wri844087.","productDescription":"Report: vi, 70 p.; 1 Plate: 16.58 x 24.21 inches","costCenters":[],"links":[{"id":57485,"rank":2,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/wri/1984/4087/report.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":57484,"rank":3,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/wri/1984/4087/plate-1.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":122672,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/wri/1984/4087/report-thumb.jpg"},{"id":414266,"rank":4,"type":{"id":36,"text":"NGMDB Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_35978.htm","linkFileType":{"id":5,"text":"html"}}],"country":"United States","state":"Montana","otherGeospatial":"West Otter area","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -106.267,\n              45.558\n            ],\n            [\n              -106.267,\n              45.425\n            ],\n            [\n              -106.133,\n              45.425\n            ],\n            [\n              -106.133,\n              45.558\n            ],\n            [\n              -106.267,\n              45.558\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4ad5e4b07f02db6838a3","contributors":{"authors":[{"text":"McClymonds, N.

Advancements in remote sensing technology have brought improvements and sophistication to modern remote sensor systems, especially those aboard earth resources satellites. These improvements have considerbly expanded the capabilities of the newer sensor systems, particularly the capability to achieve greatly increased spatial and spectral resolution levels. The debate still lingers, however, over whether future systems should maximize spatial resolution or spectral information, or both. As yet, the high costs and large volumes of data associated with even modest incremental improvements in spatial and spectral content have precluded the design of a single system that attempts to fully optimize both. Thus, the user is faced with having to choose between those systems providing high spatial resolutions but limited spectral information and those which offer a broad range of spectral data but hold spatial resolution to a less than optimum level. In this study, the contribution of both spatial resolution and spectral content to land cover change detection is examined. Ten-meter SPOT simulation imagery is compared with multispectral images acquired by the Thematic Mapper sensor system for use in the visual interpretation and mapping of changes. Several image processing and enhancement techniques are utilized to maximize the spatial and spectral data content offered by each system. Results indicate that when using visual image interpretation techniques to detect change, higher spatial resolutions are generally preferred over increased spectral content.","conferenceTitle":"Proceedings - PECORA 9: Spatial Information Technologies for Remote Sensing Today and Tomorrow.","conferenceLocation":"Sioux Falls, ND, USA","language":"English","publisher":"IEEE","publisherLocation":"New York, NY, USA","isbn":"081860588X","usgsCitation":"Milazzo, V.A., 1984, ROLE OF SPATIAL RESOLUTION AND SPECTRAL CONTENT IN CHANGE DETECTION., Proceedings - PECORA 9: Spatial Information Technologies for Remote Sensing Today and Tomorrow., Sioux Falls, ND, USA.","startPage":"69","costCenters":[],"links":[{"id":225610,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a936ae4b0c8380cd80dd8","contributors":{"authors":[{"text":"Milazzo, Valerie A.","contributorId":88717,"corporation":false,"usgs":true,"family":"Milazzo","given":"Valerie","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":367205,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

The impacts of such diversions on fish in the Great Lakes must be considered in the context of in-basin uses of the water, because in-basin uses already adversely affect the fishery resources. Temporary in-basin water withdrawals from Lake Michigan by industry in 1980 equaled 260% of the total volume of water between the shoreline and the 10-meter depth—the littoral waters most heavily used by fish as spawning and nursery grounds. Nearly 100% of the fish removed by these water withdrawals were killed.

Out-of-basin diversions of water at Chicago and at the Welland Canal, channel modifications in the St. Clair River, and in-basin consumptive water withdrawals have lowered the annual mean water level of Lakes Michigan and Huron by about 27 cm and that of Lake Erie by about 10 cm, dewatering wetlands that historically served as spawning and nursery habitat for many valuable fish species. The dollar value of fish lost to water diversions and withdrawals has not yet been estimated, but water withdrawals alone have already reduced the annual economic impact of the Great Lakes fisheries, which has been estimated to be 1.16 billion dollars.</span></p>","language":"English","publisher":"Wiley","doi":"10.1577/1548-8446(1984)009%3C0019:PIOWDO%3E2.0.CO;2","usgsCitation":"Manny, B.A., 1984,

At equilibrium a significant fraction of the alumina surface was covered by adsorbed organic matter. Cu(II) was partitioned primarily between the surface-bound organic matter and dissolved Cu-organic complexes in the aqueous phase. Complexation of Cu2+ with the functional groups of adsorbed organic matter was stronger than complexation with uncovered alumina surface hydroxyls. It is shown that the complexation of Cu(II) by adsorbed organic matter can be described by an apparent stability constant approximately equal to the value found for solution phase equilibria. In contrast, Cd(II) adsorption was not significantly affected by the presence of organic matter at the surface, due to weak complex formation with the organic ligands.

R. Doell and G. B. Dalrymple in 1973. We have determined geomagnetic paleointensities by the Thelliers' method for 14 lavas from the three sites. During these experiments, considerable difficulty was encountered because of the presence of titanomaghemite in many lavas and the contamination of natural remanent magnetization by lightning in many others. Moreover, we often observed the production of spurious high‐temperature chemical remanent magnetization during the Thellier experiments. An analysis of this particularly troublesome problem is presented. Two of the sites showed low paleointensities associated with angular departures of the paleomagnetic field direction from that of a geocentric axial dipole, which suggests that these excursions represent aborted reversals or fragments of reversals. At the third site, however, the paleointensity did not become low as the field diverged. This excursion may reflect the variation of a large nondipole source near Hawaii.</span></p>","language":"English","publisher":"AGU","doi":"10.1029/JB089iB02p01059","usgsCitation":"Coe, R.S., Gromme, S., and Mankinen, E.A., 1984, Geomagnetic paleointensities from excursion sequences in lavas on Oahu, Hawaii: Journal of Geophysical Research B: Solid Earth, v. 89, no.

The Permian and Triassic rocks are both indicated to have rotated 100° clockwise, while the Jurassic strata have rotated 60° clockwise. The respective amounts of rotation for Permian and Jurassic strata are similar along two widely-spaced transects of the arcuate Eastern Klamath terrane, which indicates rigid-block rotation rather than oroclinal bending. These results suggest that the Permian and Triassic strata began to rotate during Late Triassic or Early Jurassic time, possibly in response to the beginning of accretion of the Eastern Klamath terrane to the continental margin. Measurements on superjacent Cretaceous strata indicate that the rotation of the Eastern Klamath terrane as well as other parts of the Klamath Mountains province was virtually compete by Early Cretaceous time. The virtual cessation of rotation probably marked the completion of the accretion of the Eastern Klamath terrane to North America.

Water removed from the injection zone during injection was essentially free of oxygen. Probable growth of denitrifying bacteria and, thus, microbial denitrification, was suggested by bacterial counts in water from two observation wells that were close to the injection well. The volume fraction of treated sewage in water from wells located 35 feet and 733 feet from the injection well and open to the upper part of the injection zone stabilized at about 0.9 and 0.75, respectively.

The addition of phosphate to seawater whose fluoride concentration had been increased to 7.6 mg/l brought about an initial amorphous phosphate precipitate. After 20 months, a crystalline magnesium phosphate phase developed within the amorphous phosphate. Crystallization of apatite, which occurred during the last 3 years of the experiment, was accompanied by dissolution of the crystalline magnesium phosphate phase.</p><p>The MgO content of the apatite (1.9 percent) is high in comparison to Tertiary and older apatite but similar to some young apatite; the CO<sub>2</sub><span>&nbsp;</span>content (3.6 percent) is medium, and the fluorine content (2.2 percent) is low but again similar to some young apatite. The hydroxyl ion (OH<sup>−</sup>) likely fills the need for additional fluorine-position atoms. The mole ratio of Ca plus substituent elements to P plus substituent elements (1.50) is low in comparison to the expected ratio of 1.67. The substitution of the hydronium ion (H<sub>3</sub>O<sup>+</sup>) for Ca may account for this difference.</p><p>The synthesis of apatite in seawater demonstrates that the factor of time overcomes the well known inhibiting effect of magnesium upon the crystallization of apatite. It also implies that given an adequate supply of phosphate, apatite can form in most ocean environments and likely plays a major pan in the control of the phosphate content of seawater.</p>","language":"English","publisher":"Elsevier","doi":"10.1016/0016-7037(84)90365-X","issn":"00167037","usgsCitation":"Gulbrandsen, R.A., Roberson, C.E., and Neil, S., 1984, Time and the crystallization of apatite in seawater: Geochimica et Cosmochimica Acta, v. 48, no. 1, p. 213-218, https://doi.org/10.1016/0016-7037(84)90365-X.","productDescription":"6 p.","startPage":"213","endPage":"218","numberOfPages":"6","costCenters":[],"links":[{"id":220627,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"48","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505bb392e4b08c986b325e8b","contributors":{"authors":[{"text":"Gulbrandsen, R.

One group, type A, consists of four types of chromite: clean chromite; lattice chromite, in which the invading chlorite occurs along three directions in the (100) plane; optically zoned chromite; and poikiloblastic chromite. Most of type A chromites are surrounded by chromian clinochlore. The other group, type B, consists of euhedral to subhedral chromite grains which are included in olivine or pyroxene. The accessory chromites define a trend exhibited by chromite from other areas that have undergone metamorphism. Olivine-spinel geothermometry indicates equilibration temperatures near 700 degrees C, roughly consistent with mineral assemblages in the host gneisses.

Fluid chemical and isotopic compositions have been used to indicate the origin of water, salts and gases, original subsurface temperature and fluid flow, fluid-production mechanisms, and production-induced aquifer boiling and cold-water entry. The extensive geochemical data and interpretations for Cerro Prieto published from 1964 to 1981 are reviewed and discussed. Fluid geochemistry must continue to play an important role in the further development of the Cerro Prieto field. ?? 1984.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Geothermics","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Elsevier","doi":"10.1016/0375-6505(84)90007-5","issn":"03756505","usgsCitation":"Truesdell, A., Nehring, N., Thompson, J., Janik, C.J., and Coplen, T., 1984, A review of progress in understanding the fluid geochemistry of the Cerro Prieto geothermal system: Geothermics, v. 13, no. 1-2, p. 65-74, https://doi.org/10.1016/0375-6505(84)90007-5.","startPage":"65","endPage":"74","numberOfPages":"10","costCenters":[],"links":[{"id":480211,"rank":1,"type":{"id":41,"text":"Open Access External Repository Page"},"url":"https://www.osti.gov/biblio/7369514","text":"External Repository"},{"id":268151,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/0375-6505(84)90007-5"},{"id":220652,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"13","issue":"1-2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059e555e4b0c8380cd46cc1","contributors":{"authors":[{"text":"Truesdell, A.H.","contributorId":52566,"corporation":false,"usgs":false,"family":"Truesdell","given":"A.H.","email":"","affiliations":[{"id":6672,"text":"former: USGS Southwest Biological Science Center, Colorado Plateau Research Station, Flagstaff, AZ.
