Temporal markers are needed for reservoir sediment studies to date sediment layers deposited between the 1963–64 cesium-137 peak and the present. For two of four reservoirs studied, anomalously low organic carbon concentrations were measured for a sample interval in the upper part of a sediment core. The anomalous interval was interpreted to have been deposited during the July 1993 flood that affected a large area of the upper Mississippi River Basin. Potentially, the July 1993 flood deposit may be used as a temporal marker in reservoir bottom sediments in parts of the basin affected by the flood. Several uncertainties remain regarding the viability of organic carbon as a temporal marker including the combination of flood, basin, and reservoir characteristics required to produce a recognizable organic carbon marker in the bottom sediment and the optimal sampling strategy needed to detect the marker in a sediment core. It is proposed that flood duration and basin size may be important factors as to whether or not an anomalous and detectable organic carbon layer is deposited in a reservoir.</span></p>","language":"English","publisher":"Taylor & Francis","doi":"10.1080/07438140409354160","usgsCitation":"Juracek, K.E., 2004, Flood-related, organic-carbon anomalies as possible temporal markers in reservoir bottom sediments: Lake and Reservoir Management, v. 20, no. 4, p. 309-321, https://doi.org/10.1080/07438140409354160.","productDescription":"13 p.","startPage":"309","endPage":"321","costCenters":[],"links":[{"id":234888,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Iowa, Kansas","otherGeospatial":"Coralville Lake, Milford Lake, Perry Lake, Tuttle Creek Lake","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -91.71455383300781,\n              41.693936942282164\n            ],\n            [\n              -91.50238037109375,\n              41.693936942282164\n            ],\n            [\n              -91.50238037109375,\n              41.83989728790337\n            ],\n            [\n              -91.71455383300781,\n              41.83989728790337\n            ],\n            [\n              -91.71455383300781,\n              41.693936942282164\n            ]\n          ]\n        ]\n      }\n    },\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -97.06008911132811,\n              39.05225165582583\n            ],\n            [\n              -96.85821533203125,\n              39.05225165582583\n            ],\n            [\n              -96.85821533203125,\n              39.2758527440647\n            ],\n            [\n              -97.06008911132811,\n              39.2758527440647\n            ],\n            [\n              -97.06008911132811,\n              39.05225165582583\n            ]\n          ]\n        ]\n      }\n    },\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -96.77719116210938,\n              39.20246222588238\n            ],\n            [\n              -96.56707763671875,\n              39.20246222588238\n            ],\n            [\n              -96.56707763671875,\n              39.57817336212527\n            ],\n            [\n              -96.77719116210938,\n              39.57817336212527\n            ],\n            [\n              -96.77719116210938,\n              39.20246222588238\n            ]\n          ]\n        ]\n      }\n    },\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -95.56594848632812,\n              39.09702872683213\n            ],\n            [\n              -95.35858154296875,\n              39.09702872683213\n            ],\n            [\n              -95.35858154296875,\n              39.297111003754964\n            ],\n            [\n              -95.56594848632812,\n              39.297111003754964\n            ],\n            [\n              -95.56594848632812,\n              39.09702872683213\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"20","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a1172e4b0c8380cd53fce","contributors":{"authors":[{"text":"Juracek, Kyle E. 0000-0002-2102-8980 kjuracek@usgs.gov","orcid":"https://orcid.org/0000-0002-2102-8980","contributorId":2022,"corporation":false,"usgs":true,"family":"Juracek","given":"Kyle","email":"kjuracek@usgs.gov","middleInitial":"E.","affiliations":[{"id":353,"text":"Kansas Water Science Center","active":false,"usgs":true}],"preferred":true,"id":408012,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

Swarms during the wave train continued for ∼4 min (Mount Rainier) to ∼40 min (the Geysers) after the surface wave arrivals and were characterized by spasmodic bursts of small (<i>M</i> ≤ 2.5) earthquakes. Dynamic stresses within the surface wave train at the time of the first triggered earthquakes ranged from 0.01 MPa (Coso) to 0.09 MPa (Mount Rainier). In addition to the swarms that began during the surface wave arrivals, Long Valley caldera and Mount Rainier experienced unusually large seismic swarms hours to days after the Denali fault earthquake. These swarms seem to represent a delayed response to the Denali fault earthquake. The occurrence of spatially and temporally distinct swarms of triggered seismicity at the same site suggests that earthquakes may be triggered by more than one physical process.</p>","language":"English","publisher":"Seismological Society of America","doi":"10.1785/0120040610","usgsCitation":"Prejean, S., Hill, D., Brodsky, E.E., Hough, S., Johnston, M., Malone, S.D., Oppenheimer, D.H., Pitt, A., and Richards-Dinger, K.B., 2004, Remotely triggered seismicity on the United States west coast following the Mw 7.9 Denali fault earthquake: Bulletin of the Seismological Society of America, v. 94, no. 6B, p.

One of the earliest controversies in this new field was about what to call it. Some of the can- didate titles included “Stream Re- source Maintenance Flow,” “Base Flow,” and “Minimum Flow.” Although some of these terms were already in wide use by the early 1970’s, the term “instream flow” was not even listed in the 1973, 1974, or 1975 editions of the Water Resources Research Catalog of keywords (Doerksen 1991: 100).

Agricultural nonpoint nitrogen and phosphorus sources and urban nonpoint nitrogen sources are the most important factors associated with nutrients in this system. More than 30 percent of nitrogen yield in two basins and phosphorus yield in eight basins can be attributed to urban point source nutrient inputs. The total nitrogen yield (1.3 tons per square mile per year) for the Tombigbee River, which drains a greater percentage of agricultural (row crop) land use, was larger than the total nitrogen yield (0.99 tons per square mile per year) for the Alabama River. Decreasing trends of total nitrogen concentrations in the Tombigbee and Alabama Rivers indicate that a reduction occurred from 1975 to 1997 in the nitrogen contributions to Mobile Bay from the Mobile River.

Situated within 110&nbsp;km of Veracruz, it has experienced two major collapse events and, subsequent to its last collapse, rebuilt a massive, symmetrical summit cone. To enhance hazard mitigation efforts we assess the stability of Citlalt&eacute;petl's summit cone, the area thought most likely to fail during a potential massive collapse event. Through geologic mapping, alteration mineralogy, geotechnical studies, and stability modeling we provide important constraints on the likelihood, location, and size of a potential collapse event. The volcano's summit cone is young, highly fractured, and hydrothermally altered. Fractures are most abundant within 5&ndash;20-m wide zones defined by multiple parallel to subparallel fractures. Alteration is most pervasive within the fracture systems and includes acid sulfate, advanced argillic, argillic, and silicification ranks. Fractured and altered rocks both have significantly reduced rock strengths, representing likely bounding surfaces for future collapse events. The fracture systems and altered rock masses occur non-uniformly, as an orthogonal set with N&ndash;S and E&ndash;W trends. Because these surfaces occur non-uniformly, hazards associated with collapse are unevenly distributed about the volcano. Depending on uncertainties in bounding surfaces, but constrained by detailed field studies, potential failure volumes are estimated to range between 0.04&ndash;0.5&nbsp;km<sup class=\"a-plus-plus\">3</sup>. Stability modeling was used to assess potential edifice failure events. Modeled failure of the outer portion of the cone initially occurs as an \"intact block\" bounded by steeply dipping joints and outwardly dipping flow contacts. As collapse progresses, more of the inner cone fails and the outer \"intact\" block transforms into a collection of smaller blocks. Eventually, a steep face develops in the uppermost and central portion of the cone.

Solms) is an invasive aquatic macrophyte associated with major negative economic and ecological impacts to the Lake Victoria region since the plant's establishment in Uganda in the 1980s. Reliable estimates of water hyacinth distribution and extent are required to gauge the severity of the problem through time, relate water hyacinth abundance to environmental factors, identify areas requiring management action, and assess the efficacy of management actions. To provide such estimates and demonstrate the utility of remote sensing for this application, we processed and analyzed remotely sensed imagery to determine the distribution and extent of water hyacinth. Maps were produced and coverage was quantified using a hybrid unsupervised image classification approach with manual editing for each of the riparian countries of Kenya, Tanzania, and Uganda, as well as for numerous gulfs and bays. A similar procedure was carried out for selected lakes in the Rwanda-Tanzania borderlands lakes region in the Kagera River basin. Results confirm the severity of the water hyacinth infestation, especially in the northern parts of the lake. A maximum lake-wide extent of at least 17,374 ha was attained in 1998. Following this, a combination of factors, including conditions associated with the 1997 to 1998 El Nin??o and biocontrol with water hyacinth weevils, appear to have contributed to a major decline in water hyacinth in the most affected parts of the lake. Some lakes in the Kagera basin, such as Lake Mihindi, Rwanda, were severely infested in the late 1990s, but the level of infestation in most of these decreased markedly by the early 2000s.","language":"English","issn":"01466623","usgsCitation":"Albright, T.P., Moorhouse, T., and McNabb, T., 2004, The rise and fall of water hyacinth in Lake Victoria and the Kagera River basin, 1989-2001: Journal of Aquatic Plant Management, v. 42, no.

Soil bacterial oxidation dominated the later removal of MeBr and MeCl and was characterized by different KIEs for each compound.

We analyzed one hundred nineteen 1-cm-thick samples for pollen and algae from a set of cores that span the past 7630 years. The early middle Holocene, 7600 to 6300 cal yr B.P., was found to be the driest period, although it included one short but intense wet phase. We suggest that Lake Tahoe was below its rim for most of this period, greatly reducing the volume and depth of Pyramid Lake. Middle Holocene aridity eased between 5000 and 3500 cal yr B.P. and climate became variable with distinct wet and dry phases. Lake Tahoe probably spilled intermittently during this time. No core was recovered that represented the period between 3500 and 2600 cal yr B.P. The past 2500 years appear to have had recurrent persistent droughts. The timing and magnitude of droughts identified in the pollen record compares favorably with previously published ??18O data from Pyramid Lake. The timing of these droughts also agrees with the ages of submerged rooted stumps in the Eastern Sierra Nevada and woodrat midden data from central Nevada. Prolonged drought episodes appear to correspond with the timing of ice drift minima (solar maxima) identified from North Atlantic marine sediments, suggesting that changes in solar irradiance may be a possible mechanism influencing century-scale drought in the western Great Basin. ?? 2004 University of Washington.

A survey of visible chimney damage after the 28 February 2001 Nisqually earthquake evaluated approximately 60,000 chimneys through block-by-block coverage of about 50 km2, identifying a total of 1556 damaged chimneys. Chimney damage was strongly clustered in certain areas, in particular in the neighborhood of West Seattle where prior damage was also noted and evaluated after the 1965 earthquake. Our results showed that damage produced by the 2001 earthquake did not obviously correspond to distance from the earthquake epicenter, soft soils, topography, or slope orientation. Chimney damage correlates well to instrumented strong-motion measurements and compiled resident-reported ground-shaking intensities, but it offers much finer spatial resolution than these other data sources. In general, most areas of greatest chimney damage coincide with best estimated locations of strands of the Seattle fault zone. The edge of that zone also coincides with areas where chimney damage dropped abruptly over only one or two blocks' distance. The association between shaking intensity and fault-zone structure suggests that abrupt changes in the depth to bedrock, edge effects at the margin of the Seattle basin, or localized trapping of seismic waves in the Seattle fault zone may be significant contributory factors in the distribution of chimney damage.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Bulletin of the Seismological Society of America","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1785/0120030102","issn":"00371106","usgsCitation":"Booth, D.B., Wells, R., and Givler, R., 2004, Chimney damage in the greater Seattle area from the Nisqually earthquake of 28 February 2001: Bulletin of the Seismological Society of America, v. 94, no. 3, p. 1143-1158, https://doi.org/10.1785/0120030102.","startPage":"1143","endPage":"1158","numberOfPages":"16","costCenters":[],"links":[{"id":208297,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1785/0120030102"},{"id":233950,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"94","issue":"3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059f5b9e4b0c8380cd4c3b0","contributors":{"authors":[{"text":"Booth, D.

The parasite develops in a complex 2-host system in which the aquatic oligochaete Tubifex tubifex is an obligate host. Because substantial differences in whirling disease severity in different areas of North America did not seem explainable by environmental factors or features of the parasite or its fish host, we sought to determine whether ecological or genetic variation within oligochaete host populations may be responsible. We found large differences in compatibility between the parasite and various laboratory strains of T. tubifex that were established from geographic regions with different whirling disease histories. Moreover, 2 closely related species of tubificids, Limnodrilus hqffmeisteri and Ilyodrilus templetoni, which occur naturally in mixed species assemblages with T. tubifex, were incompatible with M. cerebralis. Virulence of the parasite was directly correlated with the numbers of triactinomyxon spores that developed within each strain of T. tubifex. Thus, the level of virulence was directly related to the compatibility between the host strain and the parasite. Genetic analyses revealed relationships that were in agreement with the level of parasite production. Differences in compatibilities between oligochaetes and M. cerebralis may contribute to the spatial variance in the severity of the disease among salmonid populations. ??

Starting in late 1994, the closed area excluded all bottom tending fishing gear capable of capturing demersal fishes. A total of 32 stations were selected inside and outside of the closed area in sand habitats. Video and still photographic transects were conducted at each station using the Seabed Observation and Sampling System (SEABOSS). Seven common (i.e. featureless sand, rippled sand, sand with emergent fauna, bare gravelly sand, gravelly sand with attached-erect fauna, whole shell, shell fragment) and 2 rare (sponges, biogenic depressions) microhabitat types were compared separately. Results showed significant differences in the relative abundance of the shell fragment and sponge microhabitat types between fished and unfished areas. The lack of differences for the other microhabitats may indicate that the level of fishing activity in the area is matched by the system's ability to recover.","largerWorkTitle":"Marine Ecology Progress Series","language":"English","doi":"10.3354/meps269061","issn":"01718630","usgsCitation":"Lindholm, J., Auster, P., and Valentine, P., 2004, Role of a large marine protected area for conserving landscape attributes of sand habitats on Georges Bank (NW Atlantic): Marine Ecology Progress Series, v. 269, p. 61-68, https://doi.org/10.3354/meps269061.","productDescription":"8 p.","startPage":"61","endPage":"68","costCenters":[{"id":186,"text":"Coastal and Marine Geology Program","active":true,"usgs":true},{"id":678,"text":"Woods Hole Coastal and Marine Science Center","active":true,"usgs":true}],"links":[{"id":478293,"rank":1,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.3354/meps269061","text":"Publisher Index Page"},{"id":235078,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","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              -70.77392578125,\n              37.92686760148135\n            ],\n            [\n              -62.1826171875,\n              37.92686760148135\n            ],\n            [\n              -62.1826171875,\n              42.50450285299051\n            ],\n            [\n              -70.77392578125,\n              42.50450285299051\n            ],\n            [\n              -70.77392578125,\n              37.92686760148135\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"269","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505aae3ce4b0c8380cd87054","contributors":{"authors":[{"text":"Lindholm, J.","contributorId":7052,"corporation":false,"usgs":true,"family":"Lindholm","given":"J.","email":"","affiliations":[],"preferred":false,"id":411623,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Auster, P.","contributorId":68614,"corporation":false,"usgs":true,"family":"Auster","given":"P.","email":"","affiliations":[],"preferred":false,"id":411624,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Valentine, P.","contributorId":83409,"corporation":false,"usgs":true,"family":"Valentine","given":"P.","affiliations":[],"preferred":false,"id":411625,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

We analyzed tufas and shells from shorelines of known ages in order to develop a relation between 87Sr/86Sr ratio of carbonates and lake level, which then can be used as a basis for constraining lake level from similar analyses on carbonates in cores. Carbonates from the late Quaternary shorelines yield the following average 87Sr/86Sr ratios: 0.71173 for the Stansbury shoreline (22-20 14C ka; 1350 m), 0.71153 for the Bonneville shoreline (15.5-14.5 14C ka; 1550 m), 0.71175 for the Provo shoreline (14.4-14.0 14C ka; 1450 m), 0.71244 for the Gilbert shoreline (???10.3-10.9 14C ka; 1300 m), and 0.71469 for the modern Great Salt Lake (1280 m). These analyses show that the 87Sr/86Sr ratio of lacustrine carbonates changes substantially at low- to mid-lake levels but is invariant at mid- to high-lake levels. Sr-isotope mixing models of Great Salt Lake and the Bonneville paleolake system were constructed to explain these variations in 87Sr/86Sr ratios with change in lake level. Our model of the Bonneville system produced a 87Sr/86Sr ratio of 0.71193, very close to the observed ratios from high-shoreline tufa and shell. The model verifies that the integration of the southern Sevier and Beaver rivers with the Bear and others rivers in the north is responsible for the lower 87Sr/86Sr ratios in Lake Bonneville compared to the modern Great Salt Lake. We also modeled the 87Sr/86Sr ratio of Lake Bonneville with the upper Bear River diverted into the Snake River basin and obtained an 87Sr/86Sr ratio of 0.71414. Coincidentally, this ratio is close to the observed ratio for Great Salt Lake of 0.71469. This means that 87Sr/86Sr ratios of >0.714 for carbonate can be produced by climatically induced low-lake conditions or by diversion of the upper Bear River out of the Bonneville basin. This model result also demonstrates that the upper Bear River had to be flowing into the Bonneville basin during highstands of other late Quaternary lake cycles: carbonates from the Little Valley (130-160 ka) and Cutler Dam (59 ?? 5 ka) lake cycles returned 87Sr/86Sr ratios of 0.71166 and 0.71207, respectively, and are too low to be produced by a lake without the upper Bear River input. ?? 2004 Geological Society of America.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Geological Society of America Bulletin","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1130/B25330.1","issn":"00167606","usgsCitation":"Hart, W., Quade, J., Madsen, D., Kaufman, D.S., and Oviatt, C.G., 2004, The 87Sr/86Sr ratios of lacustrine carbonates and lake-level history of the Bonneville paleolake system: Geological Society of America Bulletin, v. 116, no. 9-10, p. 1107-1119, https://doi.org/10.1130/B25330.1.","startPage":"1107","endPage":"1119","numberOfPages":"13","costCenters":[],"links":[{"id":209233,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1130/B25330.1"},{"id":235499,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"116","issue":"9-10","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505ba659e4b08c986b321091","contributors":{"authors":[{"text":"Hart, W.S.","contributorId":94475,"corporation":false,"usgs":true,"family":"Hart","given":"W.S.","email":"","affiliations":[],"preferred":false,"id":411123,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Quade, Jay","contributorId":22108,"corporation":false,"usgs":false,"family":"Quade","given":"Jay","affiliations":[{"id":7042,"text":"University of Arizona","active":true,"usgs":false}],"preferred":false,"id":411120,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Madsen, D.B.","contributorId":65615,"corporation":false,"usgs":true,"family":"Madsen","given":"D.B.","email":"","affiliations":[],"preferred":false,"id":411122,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Kaufman, D.

Understanding the relationships between water-quality parameters and copper toxicity may facilitate the development of site-specific criteria for water quality and result in better protection of aquatic biota. Many studies have examined the influence of a single water-quality parameter on copper toxicity, but the interactions of several characteristics have not been well studied in low-hardness water. The goal of the present research was to examine the interactions among water-quality characteristics and their effects on copper toxicity to larval fathead minnows (Pimephales promelas). The effects of dissolved organic carbon (DOC) concentration, DOC source, pH, and hardness on acute copper toxicity were determined using a complete factorially designed experiment. Hardness, pH, DOC, and interaction of pH and DOC all significantly affected copper toxicity. A predictive model based on these data described 88% of the variability in copper toxicity. This model also explained 58% of the variability in copper toxicity for an independent dataset of South Carolina (USA) waters. The biotic ligand model underpredicted the acute copper toxicity to fathead minnows when compared with observed values.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Environmental Toxicology and Chemistry","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1897/03-574.1","issn":"07307268","usgsCitation":"Sciera, K., Isely, J.J., Tomasso, J., and Klaine, S., 2004, Influence of multiple water-quality characteristics on copper toxicity to fathead minnows (Pimephales promelas): Environmental Toxicology and Chemistry, v. 23, no. 12, p. 2900-2905, https://doi.org/10.1897/03-574.1.","startPage":"2900","endPage":"2905","numberOfPages":"6","costCenters":[],"links":[{"id":208613,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1897/03-574.1"},{"id":234465,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"23","issue":"12","noUsgsAuthors":false,"publicationDate":"2004-12-01","publicationStatus":"PW","scienceBaseUri":"505a3b54e4b0c8380cd6242f","contributors":{"authors":[{"text":"Sciera, K.L.","contributorId":74550,"corporation":false,"usgs":true,"family":"Sciera","given":"K.L.","email":"","affiliations":[],"preferred":false,"id":408688,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Isely, J.

A linear equation for the erosion flux as a function of the excess bed shear stress was semicalibrated in a rotating-cylinder device called SERF (Simulator of Erosion Rate Function) and coupled to a hydrodynamic code to simulate the hole as a clear-water scour process. SERF, whose essential design is based on previous such devices, additionally included a load cell for in situ and rapid measurement of the eroded sediment mass. Based on SERF's performance and the degree of comparison between measured and simulated hole geometry, it appears that this device holds promise as a simple tool for prediction of scour in firm-clay beds. ??

In Virginia, more than 400 stream and river segments are on the Commonwealth's 2002 303(d) list because of fecal coliform impairment. Total maximum daily loads (TMDLs) will be developed for most of these listed streams and rivers. Information regarding the major fecal coliform sources that impair surface water quality would enhance the development of effective watershed models and improve TMDLs. Bacterial source tracking (BST) is a recently developed technology for identifying the sources of fecal coliform bacteria and it may be helpful in generating improved TMDLs. Bacterial source tracking was performed, watershed models were developed, and TMDLs were prepared for three streams (Accotink Creek, Christians Creek, and Blacks Run) on Virginia's 303(d) list of impaired waters. Quality assurance of the BST work suggests that these data adequately describe the bacteria sources that are impairing these streams. Initial comparison of simulated bacterial sources with the observed BST data indicated that the fecal coliform sources were represented inaccurately in the initial model simulation. Revised model simulations (based on BST data) appeared to provide a better representation of the sources of fecal coliform bacteria in these three streams. The coupled approach of incorporating BST data into the fecal coliform transport model appears to reduce model uncertainty and should result in an improved TMDL.","language":"English","publisher":"Wiley","doi":"10.1111/j.1752-1688.2004.tb01602.x","usgsCitation":"Hyer, K., and Moyer, D., 2004, Enhancing fecal coliform total maximum daily load models

The high-Cl glass grains are products of brine assimilation by tholeiite magma. The glasses are grains in a sandstone clast from bedded breccias draping the southwestern margin of Kı̄lauea’s submarine midslope bench. The clast contains two distinct suites of glass grains: abundant degassed tholeiites, perhaps derived from subaerial lavas of Mauna Loa that shattered upon ocean entry, and a smaller population of Kea-type tholeiite (</span><i>n</i><span>=17 analyzed) that erupted subaqueously, based on elevated S (780–1050 ppm), H</span><sub>2</sub><span>O (0.42–1.27 wt%), and CO</span><sub>2</sub><span> (&lt;30–120 ppm), probably early in Kı̄lauea’s shield-building stage. Ten grains in this group have Cl&gt;1000 ppm, six &gt;5000 ppm, and two grains have &gt;10 000 ppm dissolved Cl. Abundances of H</span><sub>2</sub><span>O, Na</span><sub>2</sub><span>O, K</span><sub>2</sub><span>O, and several trace elements increase regularly with Cl concentration, and we estimate that Cl enrichment was due to up to 13 wt% addition of a brine consisting of 78% H</span><sub>2</sub><span>O (wt), 13% Cl, 4.4% Na, 2.6% K, 2.6% Ca, 620 ppm Ba, 360 ppm Sr, 65 ppm Rb, and 7 ppm Pb. The large amounts of brine addition argue against bulk assimilation of low-porosity brine-bearing rock. The brine’s composition is appropriate for a seawater-derived hydrothermal fluid that reacted with basaltic wall rocks at </span><i>T</i><span>&gt;100°C, losing Mg and S and gaining K, Ca, Rb, Ba, Sr, and Pb, followed by phase separation near 500°C and ∼50 MPa (5 km below sea level at hydrostatic pressure). Brine was assimilated at or near the depth it formed, as estimated on petrologic grounds, but under lithostatic conditions. The highest extents of assimilation either forced volatile saturation of the magma or enriched already coexisting magmatic vapor in H</span><sub>2</sub><span>O. Possible mechanisms for assimilation are: (1) forcible injection of brine into magma during bursting of overpressured pockets heated by new dikes, or (2) intrusion of magma into lenses or sills occupied by trapped brine.</span></p>","language":"English","publisher":"Elsevier","doi":"10.1016/S0012-821X(03)00631-9","issn":"0012821X","usgsCitation":"Coombs, M.L., Sisson, T.W., and Kimura, J., 2004, Ultra-high chlorine in submarine Kı̄lauea glasses: Evidence for direct assimilation of brine by magma: Earth and Planetary Science Letters, v. 217, no. 3-4, p. 297-313, https://doi.org/10.1016/S0012-821X(03)00631-9.","productDescription":"17 p.","startPage":"297","endPage":"313","numberOfPages":"17","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[{"id":114,"text":"Alaska Science Center","active":true,"usgs":true},{"id":615,"text":"Volcano Hazards Program","active":true,"usgs":true}],"links":[{"id":235292,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Hawaii","otherGeospatial":"Kı̄lauea","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -155.29131889343262,\n              19.378603724290507\n            ],\n            [\n              -155.2375030517578,\n              19.378603724290507\n            ],\n            [\n              -155.2375030517578,\n              19.416816177675052\n            ],\n            [\n              -155.29131889343262,\n              19.416816177675052\n            ],\n            [\n              -155.29131889343262,\n              19.378603724290507\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"217","issue":"3-4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505bbbfde4b08c986b328963","contributors":{"authors":[{"text":"Coombs, Michelle L. 0000-0002-6002-6806 mcoombs@usgs.gov","orcid":"https://orcid.org/0000-0002-6002-6806","contributorId":2809,"corporation":false,"usgs":true,"family":"Coombs","given":"Michelle","email":"mcoombs@usgs.gov","middleInitial":"L.","affiliations":[{"id":617,"text":"Volcano Science Center","active":true,"usgs":true}],"preferred":true,"id":412234,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Sisson, Thomas W. 0000-0003-3380-6425 tsisson@usgs.gov","orcid":"https://orcid.org/0000-0003-3380-6425","contributorId":2341,"corporation":false,"usgs":true,"family":"Sisson","given":"Thomas","email":"tsisson@usgs.gov","middleInitial":"W.","affiliations":[{"id":617,"text":"Volcano Science Center","active":true,"usgs":true}],"preferred":true,"id":412236,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Kimura, Jun-Ichi","contributorId":77719,"corporation":false,"usgs":true,"family":"Kimura","given":"Jun-Ichi","email":"","affiliations":[],"preferred":false,"id":412235,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

We identified four distinct fish assemblages using cluster analysis: (1) allopatric cutthroat trout (Oncorhynchus clarki (Richardson, 1836)); (2) cutthroat trout - brook trout (Salvelinus fontinalis (Mitchell, 1814)) - Paiute sculpin (Cottus beldingi Eigenmann and Eigenmann, 1891); (3) cutthroat trout - brown trout (Salmo trutta L., 1758) - mottled sculpin (Cottus bairdi Girard, 1850); and (4) Cyprinidae-Catostomidae. The distribution of fish assemblages was explained by thermal characteristics, stream geomorphology, and local habitat features. Reaches with allopatric cutthroat trout and the cutthroat trout - brook trout - Paiute sculpin assemblage were located in high-elevation, high-gradient streams. The other two fish assemblages were generally located in low-elevation streams. Associations between habitat gradients, locations of reaches in the watershed, and occurrence of species were further examined using canonical correspondence analysis. The results suggest that stream geomorphology, thermal conditions, and local habitat characteristics influence fish assemblage structure across a Rocky Mountain watershed, and they provide information on the ecology of individual species that can guide conservation activities. ?? 2004 NRC Canada.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Canadian Journal of Zoology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1139/z04-134","issn":"00084301","usgsCitation":"Quist, M., Hubert, W., and Isaak, D., 2004, Fish assemblage structure and relations with environmental conditions in a Rocky Mountain watershed: Canadian Journal of Zoology, v. 82, no. 10, p. 1554-1565, https://doi.org/10.1139/z04-134.","startPage":"1554","endPage":"1565","numberOfPages":"12","costCenters":[],"links":[{"id":234203,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":208453,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1139/z04-134"}],"volume":"82","issue":"10","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a107be4b0c8380cd53cb5","contributors":{"authors":[{"text":"Quist, M.C. 0000-0001-8268-1839","orcid":"https://orcid.org/0000-0001-8268-1839","contributorId":62805,"corporation":false,"usgs":true,"family":"Quist","given":"M.C.","affiliations":[],"preferred":false,"id":409955,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Hubert, W.A.","contributorId":12822,"corporation":false,"usgs":true,"family":"Hubert","given":"W.A.","email":"","affiliations":[],"preferred":false,"id":409954,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Isaak, D.J.","contributorId":77326,"corporation":false,"usgs":true,"family":"Isaak","given":"D.J.","email":"","affiliations":[],"preferred":false,"id":409956,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

We examined a rare long-term record of streamflow and nitrate concentration data (1972-2000) to evaluate annual and seasonal patterns of nitrate losses in streamflow and baseflow from the Raccoon River. Combining hydrograph separation with a load estimation program, we estimated that baseflow contributes approximately two-thirds (17.3 kg/ha) of the mean annual nitrate export (26.1 kg/ha). Baseflow transport was greatest in spring and late fall when baseflow contributed more than 80% of the total export. Herein we propose a 'baseflow enrichment ratio' (BER) to describe the relation of baseflow water with baseflow nitrate loads. The long-term ratio of 1.23 for the Raccoon River suggests preferential leaching of nitrate to baseflow. Seasonal patterns of the BER identified the strong link between the baseflow nitrate loads and seasonal crop nitrogen requirements. Study results demonstrate the utility of assessing the baseflow contribution to nitrate loads to identify appropriate control strategies for reducing baseflow delivery of nitrate. ?? 2004 Elsevier B.V.

The upper SFE includes the tidal freshwater areas of the Sacramento-San Joaquin Delta downstream to the euryhaline environment of San Pablo Bay. The sampling period included years with a variety of outflow conditions. Fifty taxa were collected using a larval tow net. Two common native species, delta smelt Hypomesus transpacifucus and longfin smelt Spirinchus thaleichthys, and four common alien taxa, striped bass Morone saxatilis, threadfin shad Dorosoma petenense, gobies of the genus Tridentiger, and yellowfin goby Acanthogobins flavimanus, were selected for detailed analysis. Outflow conditions had a strong influence on the geographic distribution of most of the species, but distribution with respect to the 2 psu isohaline (X2) was not affected. The distribution patterns of delta smelt, longfin smelt, and striped bass were consistent with larvae moving from upstream freshwater spawning areas to down-stream estuarine rearing areas. There were no obvious relationships of outflow with annual abundance indices. Our results support the idea of using X2 as an organizing principle in understanding the ecology of larval fishes in the upper SFE. Additional years of sampling will likely lead to additional insights into the early life history of upper SFE fishes. ??
