Biodegradation has resulted in the formation of a plume of DOC downgradient from the oil body. Groundwater has also been contaminated in an area known as the spray zone, from vertical infiltration of DOC resulting from biodegradation of crude oil in the overlying unsaturated zone. The majority of DOC in the contaminated groundwater is in the form of nonvolatile organic acids (NVOA's) which represent the partial oxidation products of the crude oil constituents. The NVOA's have been classified into three fractions according to their isolation on XAD resins: hydrophobic neutrals (HPO-N), hydrophobic acids (HPO-A) and hydrophilic acids (HPI-A). These fractions of NVOA's were isolated from a well downgradient from the oil body (well 530; DOC=21&nbsp;mg C/l), from a well in the spray zone (well 603; DOC=15&nbsp;mg C/l) and from an uncontaminated well upgradient of the oil body where the naturally occurring DOC is 2.9&nbsp;mg C/l (well 310). The three sets of NVOA's were characterized by elemental analyses, molecular weight determinations, </span><sup>14</sup><span>C ages and liquid phase </span><sup>1</sup><span>H and </span><sup>13</sup><span>C NMR. The crude oil and the saturate, aromatic, resin and asphaltene fractions of the crude oil were similarly analyzed by elemental analysis and NMR. The NVOA's from the contaminated wells were clearly distinguishable from the naturally occurring groundwater DOC. Based upon molecular weights, sulfur contents, aromaticities and the presence of methyl groups bonded to aromatic rings, the characterization data suggests that the NVOA's originate from the C</span><sub>18</sub><span> or greater alkylaromatic, naphthenoaromatic and sulfur-containing constituents of the crude oil, including possibly the resins and asphaltenes.</span></p>","language":"English","publisher":"Elsevier","doi":"10.1016/S0146-6380(98)00167-3","usgsCitation":"Thorn, K.A., and Aiken, G., 1998, Biodegradation of crude oil into nonvolatile organic acids in a contaminated aquifer near Bemidji, Minnesota: Organic Geochemistry, v. 29, no. 4, p. 909-931, https://doi.org/10.1016/S0146-6380(98)00167-3.","productDescription":"23 p.

Metal accumulation in the cytosol and the whole body were compared in samples collected along 380 kms of a contamination gradient in the Clark Fork river in four consecutive years (1992–1995), and from a contaminated tributary (Flint Creek). Samples from the contaminated sites were compared to an uncontaminated tributary (Blackfoot River). Relations between cytosolic metal concentration and cytosolic protein (used as a general biomarker of protein metabolism) also were examined in 1994 and 1995. Relative to whole body concentrations, cytosolic metal concentrations varied among metals and years. Spatial patterns in whole body and cytosolic Cd, Cu and Pb concentrations were qualitatively similar each year, and these concentrations generally corresponded to contamination levels measured in bed sediments. The proportions of metals recovered in the cytosol of ranged from 12 to 64% for Cd and Cu and from 2 to 38% for Pb. Zinc in the whole body also was consistent with contamination levels, but cytosolic Zn concentrations increased only at the highest whole body Zn concentrations. As a result, the proportion of Zn recovered in the cytosol ranged from 16 to 63% and tended to be inversely related to whole body Zn concentrations. The proportions of cytosolic metals varied significantly among years and, as a result, interannual differences in metal concentrations were greater in the cytosol than in the whole body. The results demonstrated that Hydropsyche in the river were chronically exposed to biologically available metals. Some features of this exposure were not evident from whole body concentrations. In general, protein levels did not correspond to cytosolic metal concentrations. A variety of environmental factors could interact with metal exposures to produce complex responses in protein metabolism. Systematic study will be necessary to differentiate the effects of multiple environmental stressors on organisms living in contaminated ecosystems.</p></div></div>","language":"English","publisher":"Springer","doi":"10.1023/A:1003583117293","issn":"00188158","usgsCitation":"Cain, D., and Luoma, S., 1998, Metal exposures to native populations of the caddisfly Hydropsyche (Trichoptera: Hydropsychidae) determined from cytosolic and whole body metal concentrations: Hydrobiologia, v. 386, no. 1-3, p. 103-117, https://doi.org/10.1023/A:1003583117293.","productDescription":"15 p.","startPage":"103","endPage":"117","numberOfPages":"15","costCenters":[{"id":589,"text":"Toxic Substances Hydrology Program","active":true,"usgs":true}],"links":[{"id":227830,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"386","issue":"1-3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a547ee4b0c8380cd6cfc3","contributors":{"authors":[{"text":"Cain, D.J.","contributorId":68329,"corporation":false,"usgs":true,"family":"Cain","given":"D.J.","email":"","affiliations":[],"preferred":false,"id":385271,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Luoma, S.

The Uruk Sulcus target site was the first imaged at high resolution, and considerations of resolution, viewing geometry, low image compression, and complementary stereo imaging make this region extremely informative. Contrast variations in these low-incidence angle images are extreme and give the visual impression of topographic shading. However, photometric analysis shows that the scene must owe its character to albedo variations. A close correlation of albedo variations to topography is demonstrated by limited stereo coverage, allowing extrapolation of the observed brightness and topographic relationships to the rest of the imaged area. Distinct geological units are apparent across the region, and ridges and grooves are ubiquitous within these units. The stratigraphically lowest and most heavily cratered units (\"lineated grooved terrain\") generally show morphologies indicative of horst-and-graben-style normal faulting. The stratigraphically highest groove lanes (\"parallel ridged terrain\") exhibit ridges of roughly triangular cross section, suggesting that tilt-block-style normal faulting has shaped them. These extensional-tectonic models are supported by crosscutting relationships at the margins of groove lanes. Thus, a change in tectonic style with time is suggested in the Uruk Sulcus region, varying from horst and graben faulting for the oldest grooved terrain units to tilt block normal faulting for the latest units. The morphologies and geometries of some stratigraphically high units indicate that a strike-slip component of deformation has played an important role in shaping this region of grooved terrain. The most recent tectonic episode is interpreted as right-lateral transtension, with its tectonic pattern of two contemporaneous structural orientations superimposed on older units of grooved terrain. There is little direct evidence for cryovolcanic resurfacing in the Uruk Sulcus region; instead tectonism appears to be the dominant geological process that has shaped the terrain. A broad wavelength of deformation is indicated, corresponding to the Voyager-observed topography, and may be the result of ductile necking of the lithosphere, while a finer scale of deformation probably reflects faulting of the brittle near surface. The results here form a basis against which other Galileo grooved terrain observations can be compared.</p>","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Icarus","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Elsevier","doi":"10.1006/icar.1998.5966","issn":"00191035","usgsCitation":"Pappalardo, R.T., Head, J.W., Collins, G.C., Kirk, R.L., Neukum, G., Oberst, J., Giese, B., Greeley, R., Chapman, C.R., Helfenstein, P., Moore, J., McEwen, A.S., Tufts, B.R., Senske, D.A., Breneman, H.H., and Klaasen, K.P., 1998, Grooved Terrain on Ganymede: First Results from Galileo High-Resolution Imaging: Icarus, v. 135, no. 1, p. 276-302, https://doi.org/10.1006/icar.1998.5966.","productDescription":"27 p.","startPage":"276","endPage":"302","numberOfPages":"27","costCenters":[{"id":131,"text":"Astrogeology Science Center","active":true,"usgs":true}],"links":[{"id":487276,"rank":1,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1006/icar.1998.5966","text":"Publisher Index Page"},{"id":228232,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"otherGeospatial":"Ganymede","volume":"135","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a2a75e4b0c8380cd5b1d0","contributors":{"authors":[{"text":"Pappalardo, Robert T.","contributorId":102380,"corporation":false,"usgs":true,"family":"Pappalardo","given":"Robert","email":"","middleInitial":"T.","affiliations":[],"preferred":false,"id":385082,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Head, James W.","contributorId":70772,"corporation":false,"usgs":false,"family":"Head","given":"James","email":"","middleInitial":"W.","affiliations":[{"id":7002,"text":"Department of Earth, Environmental, and Planetary Sciences, Brown University","active":true,"usgs":false}],"preferred":false,"id":385084,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Collins, Geoffrey C.","contributorId":40512,"corporation":false,"usgs":true,"family":"Collins","given":"Geoffrey","email":"","middleInitial":"C.","affiliations":[],"preferred":false,"id":385087,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Kirk, Randolph L. 0000-0003-0842-9226 rkirk@usgs.gov","orcid":"https://orcid.org/0000-0003-0842-9226","contributorId":2765,"corporation":false,"usgs":true,"family":"Kirk","given":"Randolph","email":"rkirk@usgs.gov","middleInitial":"L.","affiliations":[{"id":131,"text":"Astrogeology Science Center","active":true,"usgs":true}],"preferred":true,"id":385089,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Neukum, Gerhard","contributorId":211350,"corporation":false,"usgs":false,"family":"Neukum","given":"Gerhard","email":"","affiliations":[],"preferred":false,"id":385092,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Oberst, Jurgen","contributorId":147983,"corporation":false,"usgs":false,"family":"Oberst","given":"Jurgen","email":"","affiliations":[],"preferred":false,"id":385091,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Giese, Bernd","contributorId":211337,"corporation":false,"usgs":false,"family":"Giese","given":"Bernd","email":"","affiliations":[],"preferred":false,"id":385078,"contributorType":{"id":1,"text":"Authors"},"rank":7},{"text":"Greeley, Ronald","contributorId":20833,"corporation":false,"usgs":true,"family":"Greeley","given":"Ronald","email":"","affiliations":[],"preferred":false,"id":385077,"contributorType":{"id":1,"text":"Authors"},"rank":8},{"text":"Chapman, Clark R.","contributorId":206278,"corporation":false,"usgs":false,"family":"Chapman","given":"Clark","email":"","middleInitial":"R.","affiliations":[{"id":37298,"text":"Southwest Research Institute, Boulder, CO","active":true,"usgs":false}],"preferred":false,"id":385079,"contributorType":{"id":1,"text":"Authors"},"rank":9},{"text":"Helfenstein, Paul","contributorId":152193,"corporation":false,"usgs":false,"family":"Helfenstein","given":"Paul","email":"","affiliations":[{"id":12722,"text":"Cornell University","active":true,"usgs":false}],"preferred":false,"id":385085,"contributorType":{"id":1,"text":"Authors"},"rank":10},{"text":"Moore, Jeffrey M.","contributorId":102585,"corporation":false,"usgs":true,"family":"Moore","given":"Jeffrey M.","affiliations":[],"preferred":false,"id":385080,"contributorType":{"id":1,"text":"Authors"},"rank":11},{"text":"McEwen, Alfred S.","contributorId":61657,"corporation":false,"usgs":false,"family":"McEwen","given":"Alfred","email":"","middleInitial":"S.","affiliations":[{"id":7042,"text":"University of Arizona","active":true,"usgs":false}],"preferred":false,"id":385081,"contributorType":{"id":1,"text":"Authors"},"rank":12},{"text":"Tufts, B.

STFs were obtained by deconvolving mainshock accelerograms by those from collocated smaller earthquakes. Accelerograms were from the U.S. Geological Survey Parkfield Small Aperture Array (UPSAR) and from a distributed array of digital accelerometer stations at Parkfield. Eight or nine STFs are used in each of the three inversions. STFs are typically symmetrical pulses with a duration of about 0.3&ndash;0.5 s. In the inversion, mainshock rise time was set to 0.05 s, and we allowed the rupture time to vary slightly from a constant rupture velocity of approximately 0.85&beta;. Rupture for all three events, which are located in or close to the Middle Mountain preparation zone or box (MMB), quickly reaches a local maximum in slip and then propagates outward to peaks, ridges, or plateaus in the slip distribution. Slip for the October 20, 1992, event (located just inside the southern edge of the MMB) propagates from an initial spike north and updip along a curving ridge for about 2 km. The initial spike continued to grow in the November 14, 1993, event (located north of the October 20, 1992, event just beneath the hypocenter of the 1966 Parkfield earthquake), which shows little directivity, although there is a smaller patch of slip updip and to the south. In contrast, rupture for the December 20, 1994, event (located just south of the October 20, 1992, event) propagated north and slightly updip, creating a rough plateau in slip a few kilometers wide on a side. Directivity for this event also is to the north. Directivity for all three events points in the approximate direction of the 1966 hypocenter. Small pulses, which comprise a coda, are found on the STFs for several seconds after the initial impulsive event. Several tests based on the assumption that the average of all STFs from UPSAR for each event is an estimate of the true slip at the source suggest that the codas in the STFs are&nbsp;</span><i>S</i><span>&nbsp;waves from a long-duration source rather than uncorrected site response. An initiation phase is found on the array average for the November 14, 1993, and December 20, 1994, events. These precursory phases are the result of a spike in slip at the hypocenter. A value of 2.4&ndash;4 mm is obtained for&nbsp;</span><i>D</i><span><i>c</i></span><span>, the slip-weakening distance, by interpreting the initial spike as a critical patch. The few aftershocks for the October 20, 1992, event are distributed to the north and updip of the mainshock, but the November 14, 1993, event had a strong burst of aftershock activity that propagated to the north of its hypocenter at roughly the same depth. Aftershocks of the December 20, 1994, event are mostly updip. The November 14, 1993, event had the simplest slip distribution, appeared to be the most impulsive, and had the most active aftershock sequence and the greatest depth. If the eventual Parkfield earthquake initiates near the 1966 hypocenter, then the directivity of the three events studied here will have pointed to it. However, it is certainly possible that both the initiation of characteristic Parkfield shocks and the directivity of smaller events are controlled by fault properties on a larger scale such as by fault bends or jogs.</span></p>","language":"English","publisher":"AGU Publications","doi":"10.1029/97JB01797","issn":"01480227","usgsCitation":"Fletcher, J.P., and Spudich, P.A., 1998, Rupture characteristics of the three M ∼ 4.7 (1992-1994) Parkfield earthquakes: Journal of Geophysical Research B: Solid Earth, v. 103, no.

However, the logistical constraints that encourage the use of satellite telemetry also inhibit efforts to assess accuracy of the resulting data. To investigate effectiveness of methods that might be used to improve the reliability of these data, we compared 3 sets of criteria designed to select the most plausible locations of polar bears (<i>Ursus maritimus</i>) that were tracked using satellite radiotelemetry in the Bering, Chukchi, East Siberian, Laptev, and Kara seas during 1988-93. We also evaluated several indices of location accuracy. Our results suggested that, although indices could provide information useful in evaluating location accuracy, no index or set of criteria was sufficient to identify all the implausible locations. Thus, it was necessary to examine the data and make subjective decisions about which locations to accept or reject. However, by using a formal set of selection criteria, we simplified the task of evaluating locations and ensured that decisions were made consistently. This approach also enabled us to evaluate biases that may be introduced by the criteria used to identify location errors. For our study, the best set of selection criteria comprised: (1) rejecting locations for which the distance to the nearest other point from the same day was &gt;50 km; (2) determining the highest accuracy code (NLOC) for a particular day and rejecting locations from that day with lesser values; and (3) from the remaining locations for each day, selecting the location closest to the location chosen for the previous transmission period. Although our selection criteria seemed unlikely to bias studies of habitat use or geographic distribution, basing selection decisions on distances between points might bias studies of movement rates or distances. It is unlikely that any set of criteria will be best for all situations; to make efficient use of data and minimize bias, these rules must be tailored to specific study objectives.</span></p>","language":"English","publisher":"International Association for Bear Research and Management","usgsCitation":"Arthur, S.M., Garner, G.W., and Olson, T.L., 1998, Identifying and mitigating errors in satellite telemetry of polar bears: Ursus, v. 10, p. 413-419.","productDescription":"7 p.","startPage":"413","endPage":"419","costCenters":[{"id":114,"text":"Alaska Science Center","active":true,"usgs":true}],"links":[{"id":337774,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":337771,"rank":1,"type":{"id":15,"text":"Index Page"},"url":"https://www.bearbiology.com/index.php?id=ursvol9_20","text":"Volume 10 on Journal's Website"}],"volume":"10","publicComments":"This volume is titled \"A selection of papers from the Tenth International Conference on Bear Research and Management, Fairbanks, Alaska, July 1995, and Mora, Sweden, September 1995.\"","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"58cba425e4b0849ce97dc7c0","contributors":{"authors":[{"text":"Arthur, Stephen M.","contributorId":189438,"corporation":false,"usgs":false,"family":"Arthur","given":"Stephen","email":"","middleInitial":"M.","affiliations":[],"preferred":false,"id":684838,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Garner, Gerald W.","contributorId":149918,"corporation":false,"usgs":false,"family":"Garner","given":"Gerald","email":"","middleInitial":"W.","affiliations":[{"id":13117,"text":"Institute of Arctic Biology, University of Alaska Fairbanks","active":true,"usgs":false}],"preferred":false,"id":684839,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Olson, Tamara L.","contributorId":29971,"corporation":false,"usgs":false,"family":"Olson","given":"Tamara","email":"","middleInitial":"L.","affiliations":[],"preferred":false,"id":684840,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

A test with a polar-quadrant grid investigates the response to local grid-scale forcing and the presence of spurious modes, a channel test case establishes convergence rates, and a field-scale test case examines problems with highly irregular grids.A finite element scheme is introduced for the 2-dimensional shallow water equations using semi-implicit methods in time.

The levels of plasma total cholesterol, free cholesterol and phospholipid of fish surviving infection were significantly higher in both yellowtail and rainbow trout than those of fish which died during the challenge test. Mortality of yellowtail with plasma total cholesterol levels lower than 250 mg/100 ml was significantly higher than that of fish which had cholesterol levels higher than 275 mg/100 ml (p < 0.05). Rainbow trout whose cholesterol was lower than 520 mg/100 ml suffered a significantly higher mortality due to vibriosis than fish having cholesterol levels higher than 560 mg/100 ml (p < 0.005).

Carp were collected from a lake (Royal Lake) that receives most of its water from irrigation return flows and from a reference lake (Billy Clapp Lake) outside of the irrigation system. Results indicated that the mean whole-brain ChE activity of carp from Royal Lake (3.47 &mu;mol/min/g tissue) was 34.2% less than that of carp from Billy Clapp Lake (5.27 &mu;mol/min/g tissue) (p&thinsp;=&thinsp;0.003). The depressed ChE activity in brain tissue of Royal Lake carp was in response to ChE-inhibiting insecticides detected in water samples in the weeks prior to tissue sampling; the most frequently detected insecticides included chlorpyrifos, azinphos-methyl, carbaryl, and ethoprop. Neither sex nor size appears to be a covariable in the analysis; ChE activity was not correlated with fish length or weight in either lake and there was no significant difference in ChE activity between the two sexes within each lake. Although organophosphate and carbamate insecticides can break down rapidly in the environment, this study suggests that in agricultural regions where insecticides are applied for extended periods of the year, nontarget aquatic biota may be exposed to high levels of ChE-inhibiting insecticides for a period of several months.</span></p>","language":"English","publisher":"Springer","doi":"10.1007/s002449900393","issn":"00904341","usgsCitation":"Gruber, S., and Munn, M., 1998, Organophosphate and carbamate insecticides in agricultural waters and cholinesterase (ChE) inhibition in common carp (<i>Cyprinus carpio</i>): Archives of Environmental Contamination and Toxicology, v. 35, no. 3, p. 391-396, https://doi.org/10.1007/s002449900393.","productDescription":"6 p.","startPage":"391","endPage":"396","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[{"id":622,"text":"Washington Water Science Center","active":true,"usgs":true}],"links":[{"id":227710,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":205971,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1007/s002449900393"}],"volume":"35","issue":"3","noUsgsAuthors":false,"publicationDate":"1998-10-01","publicationStatus":"PW","scienceBaseUri":"505a7087e4b0c8380cd760a5","contributors":{"authors":[{"text":"Gruber, S.J.","contributorId":39347,"corporation":false,"usgs":true,"family":"Gruber","given":"S.J.","email":"","affiliations":[],"preferred":false,"id":385246,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Munn, M.D.","contributorId":77908,"corporation":false,"usgs":true,"family":"Munn","given":"M.D.","email":"","affiliations":[],"preferred":false,"id":385247,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

Mean daily yields of suspended sediment from nine watersheds sampled during April and May 1994 ranged from 0.4 kg/ha of irrigated cropland in a watershed with no furrow irrigation to 19 kg/ha in a watershed where 58% of irritated cropland was in furrow irrigation. About 67% of the variation in the yields can be attributed to irrigation method. Temporal trends also indicated that use of sprinkler irrigation reduced sediment yields. Mean daily yields of suspended solids from one of the watersheds decreased from 0.3 kg/ha in 1975 to <0.2 kg/ha in 1988, corresponding with a decrease from about 65% to <50% in the use of furrow irrigation. Sampling in two watersheds suggests that the use of sprinkler irrigation reduces runoff losses of pesticides and N. For 10 of 13 pesticides and N, runoff losses from a watershed with mostly furrow irrigation exceeded runoff losses from a watershed with mostly sprinkler irrigation.","language":"English","publisher":"American Soc of Agronomy Inc","doi":"10.2134/jeq1998.00472425002700020018x","issn":"00472425","usgsCitation":"Ebbert, J., and Kim, M.H., 1998, Relation between irrigation method, sediment yields, and losses of pesticides and nitrogen: Journal of Environmental Quality, v. 27, no. 2, p. 372-380, https://doi.org/10.2134/jeq1998.00472425002700020018x.","productDescription":"9 p.","startPage":"372","endPage":"380","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[{"id":622,"text":"Washington Water Science Center","active":true,"usgs":true}],"links":[{"id":229974,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"27","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"50e4a63fe4b0e8fec6cdc141","contributors":{"authors":[{"text":"Ebbert, J.C.","contributorId":57451,"corporation":false,"usgs":true,"family":"Ebbert","given":"J.C.","affiliations":[],"preferred":false,"id":388638,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Kim, M.
