As these contaminated sub-surface environments are generally anaerobic, the microbial oxidation of aromatic compounds coupled to nitrate reduction, sulphate reduction and methane production has been studied intensively1-7. In addition, geochemical evidence suggests that Fe(III) can be an important electron acceptor for the oxidation of aromatic compounds in anaerobic groundwater. Until now, only abiological mechanisms for the oxidation of aromatic compounds with Fe(III) have been reported8-12. Here we show that in aquatic sediments, microbial activity is necessary for the oxidation of model aromatic compounds coupled to Fe(III) reduction. Furthermore, a pure culture of the Fe(III)-reducing bacterium GS-15 can obtain energy for growth by oxidizing benzoate, toluene, phenol or p-cresol with Fe(III) as the sole electron acceptor. These results extend the known physiological capabilities of Fe(III)-reducing organisms and provide the first example of an organism of any type which can oxidize an aromatic hydrocarbon anaerobically.&nbsp;</p>","language":"English","publisher":"Nature","doi":"10.1038/339297a0","issn":"00280836","usgsCitation":"Lovley, D.R., Baedecker, M., Lonergan, D., Cozzarelli, I., Phillips, E.J., and Siegel, D.I., 1989, Oxidation of aromatic contaminants coupled to microbial iron reduction: Nature, v. 339, no. 6222, p. 297-300, https://doi.org/10.1038/339297a0.","productDescription":"4 p.","startPage":"297","endPage":"300","numberOfPages":"4","costCenters":[{"id":589,"text":"Toxic Substances Hydrology Program","active":true,"usgs":true}],"links":[{"id":223502,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"339","issue":"6222","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a7263e4b0c8380cd76a83","contributors":{"authors":[{"text":"Lovley, Derek R.","contributorId":107852,"corporation":false,"usgs":true,"family":"Lovley","given":"Derek","middleInitial":"R.","affiliations":[],"preferred":false,"id":372630,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Baedecker, M.J.","contributorId":42702,"corporation":false,"usgs":true,"family":"Baedecker","given":"M.J.","email":"","affiliations":[],"preferred":false,"id":372627,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Lonergan, D.J.","contributorId":86110,"corporation":false,"usgs":true,"family":"Lonergan","given":"D.J.","email":"","affiliations":[],"preferred":false,"id":372629,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Cozzarelli, I.M. 0000-0002-5123-1007","orcid":"https://orcid.org/0000-0002-5123-1007","contributorId":22343,"corporation":false,"usgs":true,"family":"Cozzarelli","given":"I.M.","affiliations":[],"preferred":false,"id":372625,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Phillips, Elizabeth J.P.","contributorId":37475,"corporation":false,"usgs":true,"family":"Phillips","given":"Elizabeth","middleInitial":"J.P.","affiliations":[],"preferred":false,"id":372626,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Siegel, D.

Reconnaissance analysis of 1-, 3.5-, and 12-kHz data collected by the U.S. Geological Survey in the western Ross Sea has led to the identification of eight echo-character facies and six microtopographic facies in the sediment deposits that overlie the Ross Sea unconformity. Three depositional facies regions, each characterized by a particular assemblage of echo-character type and microtopographic facies, have been identified on the continental shelf. These suites of acoustic facies are the result of specific depositional processes that control type and accumulation of sediment in a region. Evidence of glacial processes and products is uncommon in regions 1 and 2, but is abundant in region 3. McMurdo Sound, region 1, is characterized by a monospecific set of acoustic facies. This unique assemblage probably represents turbidity current deposition in the western part of the basin. Most of the seafloor in region 2, from about latitude 77°S to 75°S, is deeper than 600 m below sealevel. The microtopographic facies and echo-character facies observed on the lower slopes and basin floor there reflect the thin deposits of pelagic sediments that have accumulated in the low-energy conditions that are typical of deep-water environments. In shallower water near the boundary with region 3, the signature of the acoustic facies is different from that in deeper water and probably indicates higher energy conditions or, perhaps, ice-related processes. Thick deposits of tills emplaced by lodgement during the most recent advance of the West Antarctic Ice Sheet are common from latitude 75°S to the northern boundary of the study area just south of Coulman Island (region 3). The signature of microtopographic facies in this region reflects the relief of the base of the grounded ice sheet prior to decoupling from the seafloor. Current winnowing and scour of shallow parts of the seafloor inhibits sediment deposition and maintains the irregular, hummocky relief that characterizes much of the region. Seafloor relief of this type in other polar areas could indicate the former presence of grounded ice.</div></div></div></div></div><div id=\"preview-section-introduction\"><br></div>","language":"English","publisher":"Elsevier","doi":"10.1016/0025-3227(89)90154-0","issn":"00253227","usgsCitation":"Karl, H.A., 1989, High-resolution seismic-reflection interpretations of some sediment deposits, Antarctic continental margin: Focus on the western Ross Sea: Marine Geology, v. 85, no. 2-4, p. 205-223, https://doi.org/10.1016/0025-3227(89)90154-0.","productDescription":"19 p.","startPage":"205","endPage":"223","numberOfPages":"19","costCenters":[],"links":[{"id":223886,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"85","issue":"2-4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a3129e4b0c8380cd5dcb3","contributors":{"authors":[{"text":"Karl, Herman A.","contributorId":80649,"corporation":false,"usgs":true,"family":"Karl","given":"Herman","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":371174,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

On mineral-pair ??18O plots, samples from terranes that have exchanged with large amounts of fluid typically map out steep positively-sloped non-equilibrium arrays. Analytical models are derived to explain these effects; these models allow for different exchange rates between the various minerals and the external fluids, as well as different fluid fluxes. The steep arrays are adequately modelled by calculated isochron lines that involve the whole family of possible exchange trajectories. These isochrons have initially-steep near-vertical positive slopes that rotate toward a 45?? equilibrium slope as the exchange process proceeds to completion. The actual data-point array is thus analogous to the hand of an \"isotopic clock\" that measures the duration of the hydrothermal episode. The dimensionless ratio of the volumetric fluid flux to the kinetic rate parameter ( u k) determines the shape of each individual exchange trajectory. In a fluid-buffered system ( u k ??? 1), the solutions to the equations: (1) are independent of the mole fractions of the solid phases; (2) correspond to Taylor's open-system water/rock equation; and (3) yield straight-line isochrons that have slopes that approach 1 f, where f is the fraction reacted of the more sluggishly exchanging mineral. The isochrons for this simple exchange model are closely congruent with the isochrons calculated for all of the more complex models, thereby simplifying the application of theory to actual hydrothermal systems in nature. In all of the models an order of magnitude of time (in units of kt) separates steep non-equilibrium arrays (e.g., slope ??? 10) from arrays approaching an equilibrium slope of unity on a ??-?? diagram. Because we know the approximate lifetimes of many hydrothermal systems from geologic and heat-balance constraints, we can utilize the  18O 16O data on natural mineral assemblages to calculate the kinetic rate constants (k's) and the effective diffusion constants (D's) for mineral-H2O exchange: these calculated values (kqtz ??? 10-14, kfeld ??? 10-13-10-12) agree with experimental determinations of such constants. In nature, once the driving force or energy source for the external infiltrating fluid phase is removed, the disequilibrium mineral-pair arrays will either: (1) remain \"frozen\" in their existing state, if the temperatures are low enough, or (2) re-equilibrate along specific closed-system exchange vectors determined solely by the temperature path and the mineral modal proportions. Thus, modal mineralogical information is a particularly important parameter in both the open- and closed-system scenarios, and should in general always be reported in stable-isotopic studies of mineral assemblages. These concepts are applied to an analysis of  18O 16O systematics of gabbros (Plagioclase-clinopyroxene and plagioclase-amphibole pairs), granitic plutons (quartz-feldspar pairs), and Precambrian siliceous iron formations (quartz-magnetite pairs). In all these examples, striking regularities are observed on ??-?? and ??-?? plots, but we point out that ??-?? plots have many advantages over their equivalent ??-?? diagrams, as the latter are more susceptible to misinterpretation. Using the equations developed in this study, these regularities can be interpreted to give semiquantitative information on the exchange histories of these rocks subsequent to their formation. In particular, we present a new interpretation indicating that Precambrian cherty iron formations have in general undergone a complex fluid exchange history in which the iron oxide (magnetite precursor?) has exchanged much faster with low-temperature (< 400??C) fluids than has the relatively inert quartz. ?? 1989.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Chemical Geology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Elsevier","doi":"10.1016/0009-2541(89)90019-3","issn":"00092541","usgsCitation":"Gregory, R.T., Criss, R., and Taylor, H., 1989, Oxygen isotope exchange kinetics of mineral pairs in closed and open systems: Applications to problems of hydrothermal alteration of igneous rocks and Precambrian iron formations: Chemical Geology, v. 75, no. 1-2, p. 1-42, https://doi.org/10.1016/0009-2541(89)90019-3.","startPage":"1","endPage":"42","numberOfPages":"42","costCenters":[],"links":[{"id":266087,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/0009-2541(89)90019-3"},{"id":223992,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"75","issue":"1-2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a7294e4b0c8380cd76ba7","contributors":{"authors":[{"text":"Gregory, R.

The hosts for the uranium include peat and interbedded organic-rich sand, silt, and mud that underly valley floors, fens, and marshes along stream valleys between the crest of the range and the edge of Lake Tahoe. The known uranium accumulations extend along the Carson Range from the area just southeast of South Lake Tahoe northward to the area just east of Carson City; however, they almost certainly continue beyond the study area to the north, west, and south. Due to the young age of the accumulations, uranium in them is in gross disequilibrium with its highly radioactive daughter products. These accumulations have thus escaped discovery with radiation detection equipment in the past. The uranium content of these sediments approaches 0.6 percent; however, the average is in the range of 300-500 ppm. Waters associated with these sediments locally contain as much as 177 ppb uranium. Modest levels of helium and radon also occur in these waters. Uraniferous waters are clearly entering the private and public water supply systems in some parts of the study area; however, it is not known how much uranium is reaching users of these water supplies. Many of the waters sampled in the study area exceed the published health effects guidance level of the Environmental Protection Agency. Regulatory standards for uranium in waters have not been published, however. Much uranium is stored in the sediments along these stream valleys. Estimates for a marsh and a fen along one drainage are 24,000 and 15,000 kg, respectively. The potential effects of man-induced environmental changes on the uranium are uncertain.

The attendant acidic conditions solubilise a host of trace metals. Within this flow regime the potential exists to contaminate surface drinking water supplies with a variety of trace materials. Accordingly, in evaluating the applications for mines located in the headwaters of water sheds, the pre-mining prediction of the occurrence of acid mine drainage is of paramount importance. There is general agreement among investigators that coal organic sulphur is a nonparticipant in acid mine drainage generation; however, there is no scientific documentation to support this consensus. Using simulated weathering, kinetic, mass balance, petrographic analysis and a peroxide oxidation procedure, coal organic sulphur is shown to be a nonparticipant in acid mine drainage generation.

A series of wells (shallow pits) 0.5—10 m from the adjacent channel were sampled to estimate the lateral interflow of water. Two subsurface return flows beneath the wetted channel were also examined. The conservative tracer (chloride) was hydrologically transported to all wells. Stream water was &gt;88% of flow in wells &lt;4 m from the wetted channel. The lowest percentage of stream water was 47% at a well 10 m perpendicular to the stream. Retention of solutes was greater in the hyporheic zone than in the channel under summer low—flow conditions. Nominal travel time (the interval required for chloride concentration to reach 50% of the plateau concentration) was variable by well location, indicating different flow paths and presumably permeability differences in subsurface gravels. Nominal travel time was M 24 h for wells &lt;5 m from the wetted channel. Coinjected nitrate was not conservative. Two wells were significantly (P &lt; .05) higher in nitrate—N than would be predicted from chloride, while four were significantly lower. Wells 2.0—4.0 m from the wetted channel tended to have higher nitrate concentration than predicted, whereas nitrate sink locations tended to have transport distances &gt;4.3 m. The capacity of the hyporheic zone for transient solute storage and as potential biological habitat varies with channel morphology, bed roughness, and permeability. A conceptual model that considers the groundwater—stream water interface as the fluvial boundary is proposed.

During operation, many types of wastes, including coal, tar, and oil, accumulated on site. The park soil is presently (1986) contaminated with compounds such as polynuclear aromatic hydrocarbons, volatile organic compounds, trace metals, and cyanide. Analyses of water samples from a network of observation wells in the park indicate that these compounds are also present in the groundwater. Polynuclear aromatic hydrocarbons and volatile organic compounds were identified in groundwater samples in concentrations as large as 200 mg/L. Concentrations of organic compounds were largest where groundwater was in contact with a nonaqueous phase liquid in the soil. Concentrations in groundwater were much smaller where no nonaqueous phase liquid was present, even if the groundwater was in contact with contaminated soils. This condition is attributed to weathering processes at the site, such as dissolution, volatilization, and biodegradation. Soluble, volatile, low-molecular-weight organic compounds are preferentially dissolved from the nonaqueous phase liquid into the groundwater. Where no nonaqueous phase liquid is present, only stained soils containing relatively insoluble, high-molecular-weight compounds remain; therefore, contaminant concentrations in the groundwater are much smaller. Concentrations of organic contaminants in the soils may still remain large. Values of specific conductance were as large as 5,280 microsiemens/cm, well above a background of 242 microsiemens/cm, suggesting large concentrations of minerals in the groundwater. Trace metal concentrations, however , were generally &lt; 0.010 mg/L, and below limits of US EPA drinking water standards. Cyanide was present in groundwater samples from throughout the park, ranging in concentration from 0.01 to 8.6 mg/L.&nbsp;</p>","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/wri884224","usgsCitation":"Turney, G.L., and Goerlitz, D., 1989, Ground-water contamination at an inactive coal and oil gasification plant site, Gas Works Park, Seattle, Washington: U.S. Geological Survey Water-Resources Investigations Report 88-4224, iv, 31 p., https://doi.org/10.3133/wri884224.","productDescription":"iv, 31 p.","costCenters":[],"links":[{"id":415595,"rank":3,"type":{"id":36,"text":"NGMDB Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_47120.htm","linkFileType":{"id":5,"text":"html"}},{"id":59018,"rank":2,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/wri/1988/4224/report.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":123550,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/wri/1988/4224/report-thumb.jpg"}],"country":"United States","state":"Washington","city":"Seattle","otherGeospatial":"Gas Works Park","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -122.3387400465412,\n              47.64726213325696\n            ],\n            [\n              -122.3387400465412,\n              47.64411681110258\n            ],\n            [\n              -122.33190186800769,\n              47.64411681110258\n            ],\n            [\n              -122.33190186800769,\n              47.64726213325696\n            ],\n            [\n              -122.3387400465412,\n              47.64726213325696\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b05e4b07f02db699a06","contributors":{"authors":[{"text":"Turney, G.

Analysis of flows for the Knik River is further complicated by the historic formation and outburst flooding of glacier-dammed Lake George in the Upper Knik River basin.

Median hydraulic-conductivity values were used as initial values in the model. Model-calculated estimates of hydraulic conductivity were generally lower than the statistical estimates. Simulations indicate that (1) the Pumpkin Valley Shale controls groundwater flow between Pine Ridge and Bear Creek; (2) all the recharge on Chestnut Ridge discharges to the Maynardville Limestone; (3) the formations having smaller hydraulic gradients may have a greater tendency for flow along strike; (4) local hydraulic conditions in the Maynardville Limestone cause inaccurate model-calculated estimates of hydraulic conductivity; and (5) the conductivity of deep bedrock neither affects the results of the model nor does it add information on the flow system. Improved model performance would require: (1) more water level data for the Copper Ridge Dolomite; (2) improved estimates of hydraulic conductivity in the Copper Ridge Dolomite and Maynardville Limestone; and (3) more water level data and aquifer tests in deep bedrock.&nbsp;</p>","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/wri894062","usgsCitation":"Connell, J.F., and Bailey, Z., 1989, Statistical and simulation analysis of hydraulic-conductivity data for Bear Creek and Melton Valleys, Oak Ridge Reservation, Tennessee: U.S. Geological Survey Water-Resources Investigations Report 89-4062, v, 49 p., https://doi.org/10.3133/wri894062.","productDescription":"v, 49 p.","costCenters":[],"links":[{"id":416520,"rank":3,"type":{"id":36,"text":"NGMDB Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_47176.htm","linkFileType":{"id":5,"text":"html"}},{"id":55511,"rank":2,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/wri/1989/4062/report.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":157861,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/wri/1989/4062/report-thumb.jpg"}],"country":"United States","state":"Tennessee","otherGeospatial":"Bear Creek, Melton Valley, Oak Ridge Resevation","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -84.4167,\n              36.0319\n            ],\n            [\n              -84.4167,\n              35.9\n            ],\n            [\n              -84.2194,\n              35.9\n            ],\n            [\n              -84.2194,\n              36.0319\n            ],\n            [\n              -84.4167,\n              36.0319\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b05e4b07f02db699c42","contributors":{"authors":[{"text":"Connell, J.

Devil 's Cradle Creek (agricultural watershed) had more than two times the sediment yield of Smith Creek (forested watershed) (0.34 tons/acre compared to 0.13 tons/acre), and Marsh Creek (urban watershed) had more than four times the yield of Smith Creek (0.59 tons/acre). Concentrations of nutrients were consistently highest in Devil 's Craddle Creek. Concentrations of total copper, iron, and lead in samples from each of the three streams at times exceeded State water quality standards as did concentrations of total zinc in samples from both Smith and Marsh Creeks. Successively lower aquatic invertebrate taxa richness was found in the forested, the agricultural, and the urban watershed streams. Invertebrate biota in Smith Creek was dominated by insects, such as Ephemeroptera, that are intolerant to stress from pollution, whereas Devil 's Cradle Creek was dominated by the more tolerant Diptera, and Marsh Creek was dominated by the most pollution-tolerant group, the Oligochaeta. Fish communities in the forested and agricultural watershed streams were characterized by more species and more individuals of each species, relative to a limited community in urban Marsh Creek. Three independent variables closely linked to land use--suspended-sediment yield, suspended-sediment load, and total lead concentrations in stream water--are inversely associated with the biological communities of the streams.","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/wri894007","usgsCitation":"Crawford, J.K., and Lenat, D.R., 1989, Effects of land use on the water quality and biota of three streams in the Piedmont province of North Carolina: U.S. Geological Survey Water-Resources Investigations Report 89-4007, vi, 67 p., https://doi.org/10.3133/wri894007.","productDescription":"vi, 67 p.","costCenters":[{"id":13634,"text":"South Atlantic Water Science Center","active":true,"usgs":true}],"links":[{"id":415470,"rank":3,"type":{"id":36,"text":"NGMDB Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_47137.htm","linkFileType":{"id":5,"text":"html"}},{"id":123660,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/wri/1989/4007/report-thumb.jpg"},{"id":55553,"rank":2,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/wri/1989/4007/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"country":"United States","state":"North Carolina","otherGeospatial":"Piedmont Province, Smith Creek","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -78.525,\n              35.7667\n            ],\n            [\n              -78.525,\n              36.2417\n            ],\n            [\n              -78.6667,\n              36.2417\n            ],\n            [\n              -78.6667,\n              35.7667\n            ],\n            [\n              -78.525,\n              35.7667\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4acce4b07f02db67ec79","contributors":{"authors":[{"text":"Crawford, J.

However, in 1971, the saltwater began to readvance toward the center of the well field because of water level declines caused by large increases in withdrawals during a near-record dry season. To better protect the well field, a temporary flow-regulation structure, constructed in 1971, in the Tamiami Canal was moved in 1976 to a permanent site, about 3,000 ft farther seaward; this converted that tidal reach of canal to a controlled reach under a sustained freshwater head. This water management procedure resulted in dilution of the intruding saltwater lobe and a marked concentration of its size even though large municipal withdrawals continued.

Surficial sediments were sampled for chemical and benthic infaunal analysis and bottom still photographs were taken to document bottom microtopography and epifauna at 46 stations during 12 field surveys. The surveys were performed quarterly from just before drilling began, during drilling, and for nearly 2 years after completion of drilling. Two of the eight drilling sites were selected for monitoring. Twenty-nine stations were positioned in a tight radial array around a drilling site in 80 m of water. A second group of three stations was positioned near another drilling site in 140 m of water. The remaining stations covered a broad expanse of the Bank and adjacent suspected sites of deposition of fine-grained sediments.\\</p>\n<p>&nbsp;</p>\n<p>Of the 12 elements analyzed in bulk sediments, only barium increased in concentration during the period when drilling was taking place (July 1981 to September 1982). The concentration of barium in surficial sediment increased 4&middot;7-fold from 28 ppm before drilling to 131&middot;7 ppm after drilling at the station closest to the drilling site in 80 m of water and 5&middot;9-fold from 32 ppm before drilling to 172 ppm after drilling at the station closest to the drilling site in 140 m of water. The concentrations of both barium and chromium increased in the fine (silt/clay) fraction (usually less than 5% by weight of sediment from most stations) of sediments from several stations around one or both rig sites monitored during the period of drilling. Elevated concentrations of chromium (about two-fold) occurred only in sediments near the drilling site in 140 m of water. Statistically significant increases in the concentration of barium in the fine fraction to sediment were detected approximately 65 km west (downcurrent) and 35 km east of the drilling site in 80 m of water after drilling was completed.</p>\n<p>&nbsp;</p>\n<p>The benthic fauna were abundant and diverse throughout the study area. At most stations, the dominant species remained nearly the same from one season to another over the 3 years of sampling. Polychaetes were the most abundant, followed by crustaceans. The number of individuals of some species, particularly the amphipods&nbsp;<i>Erichthonius fasciatus</i>&nbsp;and&nbsp;<i>Unciola inermis</i>, showed large seasonal variations.</p>\n<p>&nbsp;</p>\n<p>Cluster analysis revealed a strong relationship between community structure and both sediment type and water depth. Little seasonal variation was detected, but some interannual differences were revealed by cluster analysis and correspondence analysis. The replicates from a station always resembled each other more than they resembled any replicates from other stations. In addition, the combined replicates from a station always clustered with samples from that station taken on other cruises. This excellent replication and uniformity of the benthic infaunal community at a station over time made it possible to detect very subtle changes in community parameters that might be related to discharges of drilling fluid and drill cuttings. Nevertheless, no changes were detected in benthic communities of Georges Bank that could be attributed to drilling activities.</p>","language":"English","publisher":"Elsevier","doi":"10.1016/0141-1136(89)90002-0","usgsCitation":"Neff, J.M., Bothner, M., Maciolek, N.J., and Grassle, J.F., 1989, Impacts of exploratory drilling for oil and gas on the benthic environment of Georges Bank: Marine Environmental Research, v. 27, no. 2, p. 77-114, https://doi.org/10.1016/0141-1136(89)90002-0.","productDescription":"38 p.","startPage":"77","endPage":"114","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[{"id":186,"text":"Coastal and Marine Geology Program","active":true,"usgs":true}],"links":[{"id":297172,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Massachusetts","otherGeospatial":"Georges Bank","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -73.23486328124999,\n              42.827638636242284\n            ],\n            [\n              -69.6533203125,\n              42.85985981506279\n            ],\n            [\n              -69.98291015625,\n              41.57436130598913\n            ],\n            [\n              -73.54248046875,\n              42.08191667830631\n            ],\n            [\n              -73.23486328124999,\n              42.827638636242284\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"27","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"54dd2bd0e4b08de9379b34f1","contributors":{"authors":[{"text":"Neff, J.

Variations in delta flow, the principal source of variability in the bay, originate from anomalous changes in northern and central California streamflow, much of which is linked to anomalous winter sea level pressure (&ldquo;CPA&rdquo;) in the eastern Pacific. In years when CPA is strongly negative, precipitation in the watershed is heavy, delta flow is high, and the bay's salinity is low; similarly, when CPA is strongly positive, precipitation is light, delta flow is low, and the bay's salinity is high. Thus the pattern of temporal variability in atmospheric pressure anomalies is reflected in the streamflow, then in delta flow, then in estuarine variability.</p>\n</div>\n<div class=\"para\">\n<p>Estuarine salinity can be characterized by river to ocean patterns in annual cycles of salinity in relation to delta flow. Salinity (total dissolved solids) data from the relatively pristine mountain streams of the Sierra Nevada show that for a given flow, one observes higher salinities during the rise in winter flow than on the decline. Salinity at locations throughout San Francisco Bay estuary are also higher during the rise in winter flow than the decline (because it takes a finite time for salinity to fully respond to changes in freshwater flow). In the coastal ocean, however, the annual pattern of sea surface salinity is reversed: lower salinities during the rise in winter flow than on the decline due to effects associated with spring upwelling. Delta flow in spring masks these effects of coastal upwelling on estuarine salinity, including near the mouth of the estuary and, in fact, explains in a statistical sense 86 percent of the variance in salinity at the mouth of the estuary. Some of the variations in residual salinity in the bay not explained by delta flow appear to correlate with variability in coastal ocean properties. Interestingly CPA correlates also with anomalous sea surface salinity in the coastal ocean adjacent to the bay, especially in spring (albeit through a different mechanism than streamflow). For instance, when the atmospheric pressure anomaly as indicated for streamflow is high, the coastal ocean upper-layer Ekman transport is probably in the offshore direction resultingin higher sea surface salinities along the coast (with a phase lag). This circulation corresponds, in direction, to density driven estuarine circulation. In contrast a low atmospheric pressure regime leads to an onshore surface transport, and therefore opposes estuarine circulation.</p>\n</div>\n<div class=\"para\">\n<p>The influence of variations in delta flow on estuarine/phytoplankton/biochemical dynamics can be illustrated with numerical simulation models. For example, when riverflow is high the resulting low estuarine water residence time limits phytoplankton biomass and the observed effects of phytoplankton productivity on estuarine biochemistry are minimal. When riverflow is low but suspended sediment concentrations are high, light becomes a more important factor limiting phytoplankton biomass than residence time and effects of phytoplankton productivity on estuarine biochemistry are also minimal. When both riverflow and suspended sediment concentrations are low, phytoplankton biomass increases and phytoplankton productivity emerges as a major control on estuarine biochemistry: phytoplankton activity draws down and maintains very low ambient concentrations of dissolved silica and partial pressures of carbon dioxide (shifting pH to higher values). However, after an extended period of very low delta flow the major controls on estuarine biochemistry appear to change, possibly because benthic exchange processes (both sources and sinks) strengthen as salinity rises and benthic filter-feeding invertebrates migrate upstream with increasing salinity.</p>\n</div>","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"Aspects of climate variability in the Pacific and the Western Americas","largerWorkSubtype":{"id":15,"text":"Monograph"},"language":"English","publisher":"American Geophysical Union","doi":"10.1029/GM055p0419","usgsCitation":"Peterson, D.H., Cayan, D.R., Festa, J.F., Nichols, F.H., Walters, R.A., Slack, J.V., Hager, S.E., and Schemel, L.E., 1989, Climate variability in an estuary: Effects of riverflow on San Francisco Bay, chap. <i>of</i> Aspects of climate variability in the Pacific and the Western Americas, p. 419-442, https://doi.org/10.1029/GM055p0419.","productDescription":"24 p.","startPage":"419","endPage":"442","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[{"id":245,"text":"Eastern Mineral and Environmental Resources Science Center","active":true,"usgs":true},{"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":326003,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"noUsgsAuthors":false,"publicationDate":"2013-03-23","publicationStatus":"PW","scienceBaseUri":"57a1c42de4b006cb45552bfd","contributors":{"editors":[{"text":"Peterson, David H.","contributorId":147316,"corporation":false,"usgs":false,"family":"Peterson","given":"David","email":"","middleInitial":"H.","affiliations":[],"preferred":false,"id":644466,"contributorType":{"id":2,"text":"Editors"},"rank":1}],"authors":[{"text":"Peterson, David H.","contributorId":147316,"corporation":false,"usgs":false,"family":"Peterson","given":"David","email":"","middleInitial":"H.","affiliations":[],"preferred":false,"id":644458,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Cayan, Daniel R. 0000-0002-2719-6811 drcayan@usgs.gov","orcid":"https://orcid.org/0000-0002-2719-6811","contributorId":1494,"corporation":false,"usgs":true,"family":"Cayan","given":"Daniel","email":"drcayan@usgs.gov","middleInitial":"R.","affiliations":[],"preferred":false,"id":644459,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Festa, John F.","contributorId":173382,"corporation":false,"usgs":false,"family":"Festa","given":"John","email":"","middleInitial":"F.","affiliations":[],"preferred":false,"id":644460,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Nichols, Frederic H.","contributorId":25548,"corporation":false,"usgs":true,"family":"Nichols","given":"Frederic","email":"","middleInitial":"H.","affiliations":[],"preferred":false,"id":644461,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Walters, Roy A.","contributorId":74877,"corporation":false,"usgs":true,"family":"Walters","given":"Roy","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":644462,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Slack, James V.","contributorId":173383,"corporation":false,"usgs":false,"family":"Slack","given":"James","email":"","middleInitial":"V.","affiliations":[],"preferred":false,"id":644463,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Hager, Stephen E.","contributorId":34774,"corporation":false,"usgs":true,"family":"Hager","given":"Stephen","email":"","middleInitial":"E.","affiliations":[],"preferred":false,"id":644464,"contributorType":{"id":1,"text":"Authors"},"rank":7},{"text":"Schemel, Laurence E. lschemel@usgs.gov","contributorId":4085,"corporation":false,"usgs":true,"family":"Schemel","given":"Laurence","email":"lschemel@usgs.gov","middleInitial":"E.","affiliations":[],"preferred":true,"id":644465,"contributorType":{"id":1,"text":"Authors"},"rank":8}]}}
