Late Cenozoic mafic lavas crop out locally along the Jordan rift. Some of these lavas are spatially associated with thermal springs, and this association has prompted some workers to hypothesize that the hot water derives its thermal energy from the shallow, still hot intrusive roots of the volcanic rocks. However, all of the volcanic rocks appear to represent mantle-derived mafic magma that rose rather quickly to the Earth's surface, without filling crustal reservoirs within which differentiation would have produced evolved, derivative products. Moreover, the lavas are too old and of too small a volume to represent the surface expression of an active reservoir of magma within the crust. These interpretations of the volcanic geology are consistent with conclusions drawn from the chemistry of the thermal water; the water has equilibrated with host rocks at no more than 110°C, probably at depths of 2–3 km. Thus, thermal springs along the Jordan rift appear to reflect heating during circulation through a regional regime of average crustal heat flow (Galanis et at., 1986). The magmatic activity may only be a second or third order contributor to this heat flow.

Comparison of results with data from other studies in this area and from other areas, and with various water-quality standards or criteria, indicate that selenium probably is the principal contaminant of concern in the Salton Sea basin and that it probably is related to agricultural practices. Selenium is mobilized in the subsurface drainwater produced by agricultural irrigation and transported in ditches and rivers, some of which pass through or near the Salton Sea National Wildlife Refuge before entering the Salton Sea. Some selenium apparently is incorporated into the food chain. In response to the finding of elevated selenium residues in fish from the area by State agencies, the Imperial County Health Department has issued a health advisory restricting or prohibiting human consumption of fish from the Salton Sea and drains.","conferenceTitle":"Planning Now for Irrigation and Drainage in the 21st Century","conferenceDate":"18 July 1988 through 21 July 1988","conferenceLocation":"Lincoln, NE, USA","language":"English","publisher":"Publ by ASCE","publisherLocation":"New York, NY, United States","isbn":"0872626660","usgsCitation":"Schroeder, R.A., Setmire, J.G., and Wolfe, J.C., 1988, Trace elements and pesticides in Salton Sea area, California, Planning Now for Irrigation and Drainage in the 21st Century, Lincoln, NE, USA, 18 July 1988 through 21 July 1988, p. 700-707.","startPage":"700","endPage":"707","numberOfPages":"8","costCenters":[],"links":[{"id":225439,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505bb646e4b08c986b326b84","contributors":{"authors":[{"text":"Schroeder, Roy A. raschroe@usgs.gov","contributorId":1523,"corporation":false,"usgs":true,"family":"Schroeder","given":"Roy","email":"raschroe@usgs.gov","middleInitial":"A.","affiliations":[],"preferred":true,"id":368113,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Setmire, James G.","contributorId":105284,"corporation":false,"usgs":true,"family":"Setmire","given":"James","email":"","middleInitial":"G.","affiliations":[],"preferred":false,"id":368115,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Wolfe, John C.","contributorId":96021,"corporation":false,"usgs":true,"family":"Wolfe","given":"John","email":"","middleInitial":"C.","affiliations":[],"preferred":false,"id":368114,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}} ,{"id":70014295,"text":"70014295 - 1988 - Regional assessment of pumpage in southeastern Virginia","interactions":[],"lastModifiedDate":"2012-03-12T17:19:36","indexId":"70014295","displayToPublicDate":"1988-01-01T00:00:00","publicationYear":"1988","noYear":false,"publicationType":{"id":24,"text":"Conference Paper"},"publicationSubtype":{"id":19,"text":"Conference Paper"},"title":"Regional assessment of pumpage in southeastern Virginia","docAbstract":"A U.S. Geological Survey investigation was conducted, in cooperation with the Virginia Water Control Board, to analyze the hydrogeology and groundwater flow system in the Coastal Plain physiographic province of southeastern Virginia, and to assess the continued reliability of groundwater as a freshwater resource.

Ice gouges are oriented east-west and this suggests that most gouging is caused by ice approaching from the east, possibly driven by the Beaufort Sea gyre. The most intense gouging occurs in the stamukhi zone, between 20 and 40 m of water, and is caused by a high rate of ice keel production owing to shearing forces between mobile and stable sea ice. Inshore of the stamukhi zone, ice gouging still presents a significant hazard but their greatly decreased size and number make it possible to design against this hazard.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Technical Council on Cold Regions Engineering Monograph","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","isbn":"0872626393; 0872626393","usgsCitation":"Rearic, D.M., and Ticken, E.J., 1988, Ice gouge processes in the Alaskan Beaufort Sea: Technical Council on Cold Regions Engineering Monograph, p. 85-107.","startPage":"85","endPage":"107","numberOfPages":"23","costCenters":[],"links":[{"id":225687,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a37eee4b0c8380cd612c2","contributors":{"authors":[{"text":"Rearic, Douglas M.","contributorId":52969,"corporation":false,"usgs":true,"family":"Rearic","given":"Douglas","email":"","middleInitial":"M.","affiliations":[],"preferred":false,"id":367681,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Ticken, Edward J.","contributorId":32688,"corporation":false,"usgs":true,"family":"Ticken","given":"Edward","email":"","middleInitial":"J.","affiliations":[],"preferred":false,"id":367680,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}} ,{"id":70013827,"text":"70013827 - 1988 - Nitrogen cycling between sediment and the shallow-water column in the transition zone of the Potomac River and estuary.

A diffusion-controlled sampler was used to collect water samples from the water column, at the interface between the water column and sediment, and at several tens of centimeters into the sediment. Nitrate was the predominant dissolved nitrogen species in the water column. The importance of denitrification was inferred by nitrate fluxes which were directed into the sediment from the water column during approximately 75% of the sampling periods and ranged from 0·02 to 0·69 mmol m−2 day−1. Flux of nitrate from the sediment into the water column, ⩾0·1 mmol m−2 day−1, due possibly to nitrification in surficial sediment, occurred during one spring and two summer sampling periods. Ammonium fluxes were less than 0·1 mmol m−2 day−1 during 90% of the sampling periods. Of the ammonium fluxes that were >0·05 mmol m−2 day−1, all were fluxes into the sediment during sampling periods when sediment resuspension occurred, and all were into the water column during periods of calm. The mean value of ammonium flux (0·005 ± 0·05 mmol m−2 day−1) from the sandy, shallow-water sediments was two orders of magnitude less than the ammonium fluxes from the deeper, silty channel sediments in the same reach of the river. Diffusive flux calculations suggest that approximately one order of magnitude more nitrate than ammonium is cycled between the shallow-water column and the sandy sediment in the transition zone of the Potomac River.

Dried, sized, and homogenized peat that contained5980 ±307 ppm U was subjected to a variety of leaching conditions to determine the nature and strength of U-organic bonding in recently accumulated organic matter. The results complement previous experimental studies of U uptake on peat and suggest some natural or anthropogenic disturbances that are favorable for remobilizing U. The fraction of U leached in 24 h experiments at 25°C ranged from 0 to 95%. The most effective leach solutions contained anions capable of forming stable dissolved complexes with uranyl (UO2+2) cation. These included H2SO4 (pH= 1.5) and concentrated (0.01M) solutions of sodium bicarbonate-carbonate (pH= 7.0–10.0), or sodium pyrophosphate (pH= 10). Effective leaching by carbonate and pyrophosphate in the absence of added oxidant, and the insignificant effect of added oxidant (as pressurized O2) strongly suggest that U is initially fixed on organic matter as an oxidized U(VI) species. Uranium is more strongly bound than some other polyvalent cations, based on its resistance to exchange in the presence of large excesses of dissolved Ca2+ and Cu2+. Measurements of the rate of U leaching indicate faster rates in acid solution compared to carbonate solution, and are consisten with simultaneous attack of sites with different affinities for U. Sulfuric acid appears a good choice for commercial extraction of U from mined peat.In situ disturbances such as overliming of peat soils, addition of fertilizers containing pyrophosphate, or incursions of natural carbonate-rich waters could produce significant remobilization of U, and possibly compromise the quality of local domestic water supplies.
This study demonstrates the feasibility of using low-altitude aerial photography to inventory submersed macrophytes in the connecting channels of the Great Lakes. For this purpose, we obtained aerial color transparencies and collateral ground truth information about submersed vegetation at 160 stations within four study sites in the St. Clair and Detroit rivers, September 17 to October 4, 1984. Photographs were interpreted by five test subjects to determine with what accuracy they could detect beds of submersed macrophytes, and the precision of delineating the extent of such vegetation beds. The interpreters correctly determined the presence or absence of vegetation 80% of the time (range 73-86%). Differences between individuals were statistically significant. Determination of the presence or absence of macrophytes depended partly on their relative abundance and water clarity. Analysis of one photograph from each of the four study sites revealed that photointerpreters delineated between 35 and 75 ha of river bottom covered by vegetation. This wide range indicates that individuals should be tested to assess their relative capability and be trained before they are employed to delineate plant beds in large-scale inventories. Within limits, low-altitude aerial photography, combined with collateral ground truth information, can be used to determine the presence or absence and delineate the extent of submersed macrophytes in connecting channels of the Great Lakes.

Off Antarctica, sidescan sonar data indicate the presence of ice-gouge features formed by the physical interaction between ice keels and the sea bed. These are recognized as incisions a few metres deep and tens of metres wide, in water depths up to 500 m. On the submarine bank tops and slopes off Wilkes Land and in the Weddell Sea, subcircular depressions 30 to 150 m in diameter, a washboard pattern, and hummocky bed features also represent iceberg-resting sites. The freshness of sea-bed morphology, nearby Holocene sediment ponding, and active hydraulic sedimentary processes indicate that the sea floor is being reworked by iceberg keels. Tabular iceberg drafts in excess of 330 m have been measured, and modeling studies suggest that nontabular iceberg drafts of 500 m are possible. We conclude that a modern ice-keel turbate deposit in the form of a poorly stratified diamicton is probably widespread on that part (54%) of the Antarctic shelf less than 500 m deep.
Vapor sorption of water, ethanol, benzene, hexane, carbon tetrachloride, 1,1,1-trichloroethane, trichloroethylene, tetrachloroethylene, and 1,2-dibromoethane on (Sanhedron) soil humic acid has been determined at room temperature. Isotherms for all organic liquids are highly linear over a wide range of relative pressure, characteristic of the partitioning (dissolution) of the organic compounds in soil humic acid. Polar liquids exhibit markedly greater sorption capacities on soil humic acid than relatively nonpolar liquids, in keeping with the polar nature of the soil humic acid as a partition medium. The limiting sorption (partition) capacities of relatively non-polar liquids are remarkably similar when expressed in terms of volumes per unit weight of soil humic acid. The soil humic acid is found to be about half as effective as soil organic matter in sorption of relatively nonpolar organic compounds. The nearly constant limiting sorption capacity for nonpolar organic liquids with soil humic acid on a volume-to-weight basis and its efficiency in sorption relative to soil organic matter provide a basis for predicting the approximate sorption (partition) coefficients of similar compounds in uptake by soil in aqueous systems.

Slimy and spoonhead sculpins occupy a zone from near shore to depths of 210 m but are generally most abundant in waters 50 to 90 m deep. Deepwater sculpins are found in waters from 15 to 407 m deep and are most abundant at depths greater than 70 m. All three species of sculpins eat mainly burrowing amphipods (Pontoporeia affinis) although deepwater sculpins also eat substantial quantities of opossum shrimp (Mysis relicta). The three sculpins grow at similar rates. Among the fishes aged, the maximum age of slimy sculpins was 5 years, compared with 6 years for spoonhead sculpins, and 7 years for deepwater sculpins. Indirect evidence indicates that slimy and spoonhead sculpins spawn in the spring, and deepwater sculpins spawn in midwinter.

Commonly, measurement accuracy and resolution have been limited by a borehole environment consisting of an annulus of disturbed sediments produced by the casing-installation method. In an attempt to quantify this disturbance and recognize its impact on the characterization of unconsolidated deposits, three installation methods were examined and compared in a sand-and-gravel outwash at a test site on Cape Cod, Massachusetts. These installation methods were: 1) casing installed in a mud-rotary hole; 2) casing installed in an augered hole; and 3) flush-joint steel casing hammer-driven from land surface. Fifteen wells were logged with epithermal neutron and natural gamma tools. Concludes that augering is the most disruptive of the three casing-installation methods and that driving casing directly, though typically a more time-consuming operation, transmits the least amount of disturbance into the surrounding formation. -from Authors","language":"English","publisher":"Wiley","doi":"10.1111/j.1745-6584.1988.tb00385.x","issn":"0017467X","usgsCitation":"Morin, R.H., LeBlanc, D.R., and Teasdale, W., 1988, A statistical evaluation of formation disturbance produced by well- casing installation methods: Ground Water, v. 26, no. 2, p. 207-217, https://doi.org/10.1111/j.1745-6584.1988.tb00385.x.","productDescription":"11 p.","startPage":"207","endPage":"217","numberOfPages":"11","costCenters":[{"id":589,"text":"Toxic Substances Hydrology Program","active":true,"usgs":true}],"links":[{"id":225445,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Massachusetts ","otherGeospatial":"Cape Cod","geographicExtents":"{\n \"type\": \"FeatureCollection\",\n \"features\": [\n {\n \"type\": \"Feature\",\n \"properties\": {},\n \"geometry\": {\n \"type\": \"Polygon\",\n \"coordinates\": [\n [\n [\n -70.83984375,\n 41.6154423246811\n ],\n [\n -69.862060546875,\n 41.6154423246811\n ],\n [\n -69.862060546875,\n 42.16340342422401\n ],\n [\n -70.83984375,\n 42.16340342422401\n ],\n [\n -70.83984375,\n 41.6154423246811\n ]\n ]\n ]\n }\n }\n ]\n}","volume":"26","issue":"2","noUsgsAuthors":false,"publicationDate":"2006-03-21","publicationStatus":"PW","scienceBaseUri":"5059e5afe4b0c8380cd46efb","contributors":{"authors":[{"text":"Morin, R.

The refuge lies within the northern boreal subzone of northwestern central Alaska. Six major vegetation classes and 21 subclasses were recognized: forest (closed needleleaf, open needleleaf, needleleaf woodland, mixed, and broadleaf); broadleaf scrub (lowland, upland burn regeneration, subalpine); dwarf scrub (prostrate dwarf shrub tundra, erect dwarf shrub heath, dwarf shrub-graminoid peatland, dwarf shrub-graminoid tussock peatland, dwarf shrub raised bog with scattered trees, dwarf shrub-graminoid marsh); herbaceous (graminoid bog, graminoid marsh, graminoid tussock-dwarf shrub peatland); scarcely vegetated areas (scarcely vegetated scree and floodplain); and water (clear, sedimented). The methodology employed a cluster-block technique. Sample areas were described based on a combination of helicopter-ground survey, aerial photo-interpretation, and digital Landsat data. Major steps in the Landsat analysis involved preprocessing (geometric correction), derivation of statistical parameters for spectral classes, spectral class labeling of sample areas, preliminary classification of the entire study area using a maximum-likelihood algorithm, and final classification utilizing ancillary information such as digital elevation data. The final product is 1:250,000-scale vegetation map representative of distinctive regional patterns and suitable for use in comprehensive conservation planning.

Low levels of morbidity and mortality from avian botulism occurred on the two ponds throughout both summers, but there was no apparent relationship between the occurrence or rates of botulism losses and drawdowns of the ponds. Botulism also occurred throughout both summers on other areas of the refuge. Botulinal toxin was found in fly larvae associated with avian carcasses, including birds that did not die from botulism. Toxin was not found in other samples of aquatic biota in the ponds, although it was demonstrated in a single sample of decomposing sea lettuce (Ulva lactuca) in Jamaica Bay. Aspergillosis (Aspergillus fumigatus) and salmonellosis (Salmonella spp.) were also frequently-diagnosed causes of morbidity and mortality. We believe that botulinal toxin present in carcasses of birds dying from botulism, or produced postmortem in birds dying from other causes, on the two ponds and other areas in Jamaica Bay were a major source of botulinal toxin. Toxin could be ingested by birds through direct scavenging on carcasses, or by consumption of toxic fly larvae associated with carcasses. Diligent carcass pickup at the two ponds is recommended to reduce mortality from avian botulism.

In this report we present the results of a long-term tag-recapture study as well as corroborative evidence of stock discreteness fromstudies of population characteristics such as growth and allelic frequencies of walleye in these waters. Walleye were tagged in the spring from 1975-87 in lakes St. Clair and Erie. Tag-recapture data indicate a general tendency for walleye to move northward after tagging. Walleye tagged in Lake St. Clair had higher recovery rates and lower survival rates than walleye tagged in Lake Erie. A reward-tag study in Lake St. Clair provided an estimate of a non-reporting rate of approximately 33% which is comparable to rates in the literature for other species. Data from the Ontario commercial (gill-net) fishery, Michigan Department of Natural Resources trap-net surveys, and sport fisheries from western Lake Erie and Lake St. Clair were analyzed with a catch-at-age model which permitted estimation of population abundance (12.2 to 34.5 million fish), fishing mortality rate (0.19 to 0.37), and annual survival rate (0.57 to 0.68). It appears that exploitation rates for the sport fishery in the western basin exceeded those of the commercial fishery from 1978-82. In recent years (1983-87), exploitation rates were comparable. Average abundance and catch of walleye in the western basin were 12.2 million and 3.4 million fish in 1978-82; average abundance and catch in 1983-87 were 34.5 and 5.2 million fish. We found good agreement between the estimate of the harvest from creel surveys and that from the catch-at-age model for Lake Erie. Walleye abundance and harvest in Lake St. Clair were 10% of the values for the western basin of Lake Erie. Two discrete stocks were delineated be analysis of allelic frequencies of samples from Lake St. Clair and Lake Erie spawning populations. These two stocks are the western basin of Lake Erie and Lake St. Clair stocks. No further subdivision of stocks was possible based on the genetic analysis of 21 loci. These genetically different stocks intermix in the northern waters of this system. Based on a consideration of the results of the genetic analysis, catch-at-age analysis, and tag-recapture study we recommend independent but coordinated management of the walleye populations in Lake St. Clair and Lake Erie.","language":"English","publisher":"U.S. Fish and Wildlife Service","usgsCitation":"Haas, R.C., Fabrizio, M.C., and Todd, T.N., 1988, Identification, movement, growth, mortality, and exploitation of walleye stocks in Lake St. Clair and the western basin of Lake Erie: Fisheries Research Report 1954, 71 p.","productDescription":"71 p.","startPage":"0","endPage":"71","numberOfPages":"71","costCenters":[{"id":324,"text":"Great Lakes Science Center","active":true,"usgs":true}],"links":[{"id":198276,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a09e4b07f02db5faa06","contributors":{"authors":[{"text":"Haas, Robert C.","contributorId":97450,"corporation":false,"usgs":true,"family":"Haas","given":"Robert","email":"","middleInitial":"C.","affiliations":[],"preferred":false,"id":326472,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Fabrizio, Mary C.","contributorId":77471,"corporation":false,"usgs":true,"family":"Fabrizio","given":"Mary","email":"","middleInitial":"C.","affiliations":[],"preferred":false,"id":326471,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Todd, Thomas N.","contributorId":42547,"corporation":false,"usgs":true,"family":"Todd","given":"Thomas","email":"","middleInitial":"N.","affiliations":[],"preferred":false,"id":326470,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}} ]}
