We applied adaptive cluster sampling to estimate density of freshwater mussels at 24 sites along the Cacapon River, WV, where a preliminary timed search indicated that mussels were present at low density. Adaptive cluster sampling increased yield of individual mussels and detection of uncommon species; however, it did not improve precision of density estimates. Because finding uncommon species, collecting individuals of those species, and estimating their densities are important conservation activities, additional research is warranted on application of adaptive cluster sampling to freshwater mussels. However, at this time we do not recommend routine application of adaptive cluster sampling to freshwater mussel populations. The ultimate, and currently unanswered, question is how to tell when adaptive cluster sampling should be used, i.e., when is a population sufficiently rare and clustered for adaptive cluster sampling to be efficient and practical? A cost-effective procedure needs to be developed to identify biological populations for which adaptive cluster sampling is appropriate.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Environmental and Ecological Statistics","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1023/A:1021956617984","issn":"13528505","usgsCitation":"Smith, D., Villella, R., and Lemarie, D.P., 2003, Application of adaptive cluster sampling to low-density populations of freshwater mussels: Environmental and Ecological Statistics, v. 10, no. 1, p. 7-15, https://doi.org/10.1023/A:1021956617984.","startPage":"7","endPage":"15","numberOfPages":"9","costCenters":[],"links":[{"id":208936,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1023/A:1021956617984"},{"id":235053,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"10","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059ec94e4b0c8380cd4936a","contributors":{"authors":[{"text":"Smith, D.

Toxicity tests were performed with formalin (paracide-F, 37% formaldehyde) to determine the appropriate levels of treatment for eradicating these flatworms from host fish tanks without adversely affecting the culture of juvenile mussels. Results indicate that a 1-h shock treatment of 250 mg/L formalin or a 3-d continuous exposure to 20 mg/L of formalin kills adult Macrostomum but not fish. Observations indicate that a single treatment is insufficient to kill Macrostomum eggs, so a second treatment after 3 d is necessary to kill newly hatched flatworms. Newly metamorphosed freshwater mussels exposed to similar shock and continuous treatments of formalin were also killed. Thus, all host fish introduced for the purpose of mussel production should be quarantined and treated prophylactically to avoid the infestation of mussel culture systems with predacious flatworms.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"North American Journal of Aquaculture","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1577/1548-8454(2003)065<0028:COPFMS>2.0.CO;2","issn":"15222055","usgsCitation":"Zimmerman, L., Neves, R.J., and Smith, D., 2003, Control of predacious flatworms Macrostomum sp. in culturing juvenile freshwater mussels: North American Journal of Aquaculture, v. 65, no. 1, p. 28-32, https://doi.org/10.1577/1548-8454(2003)065<0028:COPFMS>2.0.CO;2.","startPage":"28","endPage":"32","numberOfPages":"5","costCenters":[],"links":[{"id":208762,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1577/1548-8454(2003)065<0028:COPFMS>2.0.CO;2"},{"id":234735,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"65","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059fb43e4b0c8380cd4ddb1","contributors":{"authors":[{"text":"Zimmerman, L.L.","contributorId":88921,"corporation":false,"usgs":true,"family":"Zimmerman","given":"L.L.","email":"","affiliations":[],"preferred":false,"id":408132,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Neves, R.

Interactions between heated sea water and molten basaltic lava could exert significant control on the dynamics of lava flows and on their chemistry. But it has been thought that heating sea water at pressures of several hundred bars cannot produce significant amounts of vapour and that a thick crust of chilled glass on the exterior of lava flows minimizes the interaction of lava with sea water. Here we present evidence to the contrary, and show that bubbles of vaporized sea water often rise through the base of lava flows and collect beneath the chilled upper crust. These bubbles of steam at magmatic temperatures may interact both chemically and physically with flowing lava, which could influence our understanding of deep-sea volcanic processes and oceanic crustal construction more generally. We infer that vapour formation plays an important role in creating the collapse features that characterize much of the upper oceanic crust and may accordingly contribute to the measured low seismic velocities in this layer.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Nature","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1038/nature02032","issn":"00280836","usgsCitation":"Perfit, M., Cann, J., Fornari, D., Engels, J., Smith, D., Ridley, W., and Edwards, M., 2003, Interaction of sea water and lava during submarine eruptions at mid-ocean ridges: Nature, v. 426, no. 6962, p. 62-65, https://doi.org/10.1038/nature02032.","startPage":"62","endPage":"65","numberOfPages":"4","costCenters":[],"links":[{"id":207748,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1038/nature02032"},{"id":232934,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"426","issue":"6962","noUsgsAuthors":false,"publicationDate":"2003-11-06","publicationStatus":"PW","scienceBaseUri":"505a3cb7e4b0c8380cd62f9b","contributors":{"authors":[{"text":"Perfit, M.R.","contributorId":45467,"corporation":false,"usgs":true,"family":"Perfit","given":"M.R.","email":"","affiliations":[],"preferred":false,"id":403118,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Cann, J.R.","contributorId":100158,"corporation":false,"usgs":true,"family":"Cann","given":"J.R.","email":"","affiliations":[],"preferred":false,"id":403122,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Fornari, D.J.","contributorId":49520,"corporation":false,"usgs":true,"family":"Fornari","given":"D.J.","email":"","affiliations":[],"preferred":false,"id":403119,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Engels, J.","contributorId":70152,"corporation":false,"usgs":true,"family":"Engels","given":"J.","affiliations":[],"preferred":false,"id":403120,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Smith, D.K.","contributorId":17013,"corporation":false,"usgs":true,"family":"Smith","given":"D.K.","email":"","affiliations":[],"preferred":false,"id":403116,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Ridley, W.I.","contributorId":72122,"corporation":false,"usgs":true,"family":"Ridley","given":"W.I.","email":"","affiliations":[],"preferred":false,"id":403121,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Edwards, M.H.","contributorId":33888,"corporation":false,"usgs":true,"family":"Edwards","given":"M.H.","email":"","affiliations":[],"preferred":false,"id":403117,"contributorType":{"id":1,"text":"Authors"},"rank":7}]}}

Aquatic biodiversity in hemlock ecosystems has not been documented; thus the true impact of the infestation cannot be assessed. We compared ichthyofaunal assemblages and trophic structure of streams draining hemlock and hardwood forests by sampling first- and second-order streams draining 14 paired hemlock and hardwood stands during base flows in July 1997 at the Delaware Water Gap National Recreation Area of Pennsylvania and New Jersey. Over 1400 fish of 15 species and 7 families were collected, but hemlock and hardwood streams individually harbored only one to four species. Brook trout (Salvelinus fontinalis) and brown trout (Salmo trutta) were two to three times as prevalent in hemlock than hardwood streams. Insectivorous fishes occurred in significantly higher proportion in streams of hardwood (0.90) than hemlock (0.46) stands, while piscivores occurred more often in hemlock (0.85) than hardwood (0.54) stands. Functional (trophic) diversity of fishes in hemlock and second-order streams was numerically greater than that of hardwood and first-order streams. Species composition also differed by stream order and terrain type.

Measurements were made on grids of about 1000 square meters using a very shallow penetrating (less than 10 m) electromagnetic (EM) geophysical system (EM31). At site A, high subsurface conductivities (more than 100 millisiemens per meter) found below disposal ponds extended down the local hydrologic gradient to below the normal level of near by Lake Skiatook. At site B, areas of highest subsurface electrical conductivity were offset about 10 m from the center of salt scars. The area of high subsurface electrical conductivity extends in the subsurface below the normal level of Skiatook Lake. DC resistivity soundings were made in and around the two sites in order to characterize deeper (30-60 m) electrical properties of the subsurface lithology and ground water. These soundings indicate that the tight shale that dominates the local lithology is moderately electrically conductive (5 milliseimems per meter). DC soundings done in several areas at the Skiatook Lake shoreline indicate an electrically conductive (less than 10 millisiemens per meter) zone exists below the shore even away from the oil production sites. This conductive zone may indicate a mixing between fresh lake water and local ground water that has high dissolved solids. Borehole geophysical logs at site B and laboratory rock property measurements are currently being used to refine interpretation of ground geophysical measurements.</span></p>","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"9th International Petroleum Environmental Conference","largerWorkSubtype":{"id":12,"text":"Conference

The radar system uses identical directional cavity-backed monopole transmitting and receiving antennas that can be mechanically rotated while the tool is stationary or moving slowly in a borehole. Faster reconnaissance logging with no antenna rotation was also done to find zones of interest. The microprocessor-controlled motor/encoder in the tool can rotate the antennas azimuthally, to a commanded angle, accurate to a within few degrees. The three logged wells in the unsaturated zone at the INEEL had been cored with good core recovery through most zones. After coring, PVC casing was installed in the wells. The unsaturated zone consists of layered basalt flows that are interbedded with thin layers of coarse-to-fine grained sediments. Several zones were found that show distinctive signatures consistent with fractures in the basalt. These zones may correspond to suspected preferential flow paths. The DBOR data were compared to core, and other borehole log information to help provide better understanding of hydraulic flow and transport in preferential flow paths in the unsaturated zone basalts at the INEEL.","largerWorkTitle":"Proceedings of SPIE - The International Society for Optical Engineering","conferenceTitle":"9th International Conference on Ground Penetrating Radar","conferenceDate":"29 April 2002 through 2 May 2002","conferenceLocation":"Santa Barbara, CA","language":"English","doi":"10.1117/12.462208","issn":"0277786X","usgsCitation":"Moulton, C., Wright, D., Hutton, S., Smith, D., and Abraham, J., 2002, Basalt-flow imaging using a high-resolution directional borehole radar, <i>in</i> Proceedings of SPIE - The International Society for Optical Engineering, v. 4758, Santa Barbara, CA, 29 April 2002 through 2 May 2002, p. 13-18, https://doi.org/10.1117/12.462208.","startPage":"13","endPage":"18","numberOfPages":"6","costCenters":[],"links":[{"id":209567,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1117/12.462208"},{"id":236170,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"4758","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059efc2e4b0c8380cd4a433","contributors":{"authors":[{"text":"Moulton, C.W.","contributorId":81681,"corporation":false,"usgs":true,"family":"Moulton","given":"C.W.","email":"","affiliations":[],"preferred":false,"id":403658,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Wright, D.L.","contributorId":88758,"corporation":false,"usgs":true,"family":"Wright","given":"D.L.","email":"","affiliations":[],"preferred":false,"id":403659,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Hutton, S.R.","contributorId":50337,"corporation":false,"usgs":true,"family":"Hutton","given":"S.R.","email":"","affiliations":[],"preferred":false,"id":403656,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Smith, D.V.G.","contributorId":57249,"corporation":false,"usgs":true,"family":"Smith","given":"D.V.G.","email":"","affiliations":[],"preferred":false,"id":403657,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Abraham, J.D.","contributorId":20686,"corporation":false,"usgs":true,"family":"Abraham","given":"J.D.","email":"","affiliations":[],"preferred":false,"id":403655,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}}

All observed scent-marking (</span><i>N</i><span> = 158) was done by breeding wolves, primarily dominant individuals. Dominant breeding pairs provided most leadership, consistent with a trend in social mammals for leadership to correlate with dominance. Dominant breeding wolves led traveling packs during 64% of recorded behavior bouts (</span><i>N</i><span> = 591) and 71% of observed travel time (</span><i>N</i><span> = 64 h). During travel, breeding males and females led packs approximately equally, which probably reflects high parental investment by both breeding male and female wolves. Newly initiated behaviors (</span><i>N</i><span> = 104) were prompted almost 3 times more often by dominant breeders (70%) than by nonbreeders (25%). Dominant breeding females initiated pack activities almost 4 times more often than subordinate breeding females (30 vs. 8 times). Although one subordinate breeding female led more often than individual nonbreeders in one pack in one season, more commonly this was not the case. In 12 cases breeding wolves exhibited nonfrontal leadership. Among subordinate wolves, leadership behavior was observed in subordinate breeding females and other individuals just prior to their dispersal from natal packs.

In early 1999 a workshop was held at the behest of the Atlantic States Marine Fisheries Commission to design a statistically valid survey of horseshoe crab spawning in Delaware Bay. The survey that resulted was a redesign of a volunteer-based spawning survey that began in 1990, and its network of volunteers was relied on to implement the three-stage sampling design in 1999. During May and June of 1999, 163 participants surveyed during the highest of the daily high tides on 16 beaches (8 on each site of Delaware Bay). During the first half of the spawning season, spawning was associated with lunar phases, but moderated by wave height. Disproportionately more spawning occurred within 3 d of the first new and full moons, and spawning activity (measured by an index of female density) was correlated inversely to the percent of beaches with waves ≥0.3 m. Spawning was heaviest on the Delaware shore around the full moon in May in spite of low waves in New Jersey during the new and full moons in May. Number of beaches sampled was the most important factor in determining the precision of the spawning index and power to detect a decline. Explicit consideration of statistical power has been absent from the current debate on horseshoe crab status and harvest. Those who argue against harvest restrictions because of a lack of statistically significant declines take on a burden to show that the surveys they cite have high statistical power. We show the Delaware Bay spawning survey will achieve high statistical power with sufficient sampling intensity and duration. We recommend that future Delaware Bay spawning surveys sample on 3 d around each new and full moon in May and June and increase the number of beaches to ensure high statistical power to detect trends in baywide spawning activity.</span></p>","language":"English","publisher":"Springer","doi":"10.1007/BF02696055","usgsCitation":"Smith, D., Pooler, P., Swan, B., Michels, S., Hall, W., Himchak, P., and Millard, M.J., 2002, Spatial and temporal distribution of horseshoe crab (Limulus polyphemus) Spawning Delaware Bay: Implications for monitoring: Estuaries, v. 25, no. 1, p. 115-125, https://doi.org/10.1007/BF02696055.","productDescription":"11 p.","startPage":"115","endPage":"125","costCenters":[{"id":365,"text":"Leetown Science Center","active":true,"usgs":true}],"links":[{"id":130100,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Delaware, New Jersey","otherGeospatial":"Delaware Bay","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -75.421142578125,\n              39.081040177486095\n            ],\n            [\n              -75.30853271484374,\n              38.88889501576177\n            ],\n            [\n              -75.2178955078125,\n              38.805470223177466\n            ],\n            [\n              -75.08880615234375,\n              38.777640223073355\n            ],\n            [\n              -74.9761962890625,\n              38.82045110711473\n            ],\n            [\n              -74.96246337890625,\n              38.953001345359894\n            ],\n            [\n              -74.89654541015625,\n              39.08530414503412\n            ],\n            [\n              -74.90203857421875,\n              39.22587043822116\n            ],\n            [\n              -75.43762207031251,\n              39.281167913914636\n            ],\n            [\n              -75.421142578125,\n              39.081040177486095\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"25","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e49e5e4b07f02db5e6f48","contributors":{"authors":[{"text":"Smith, D.

If not specifically accounted for a priori, this noise can weaken comparisons between sites, and can make it difficult to draw inferences about specific ecological processes. We developed a terrain-based, paired-site sampling design to analyze differences in aquatic biodiversity between streams draining eastern hemlock (Tsuga canadensis) forests, and those draining mixed hardwood forests in Delaware Water Gap National Recreation Area (USA). The goal of this design was to minimize variance due to terrain influences on stream communities, while representing the range of hemlock dominated stream environments present in the park. We used geographic information systems (GIS) and cluster analysis to define and partition hemlock dominated streams into terrain types based on topographic variables and stream order. We computed similarity of forest stands within terrain types and used this information to pair hemlock-dominated streams with hardwood counterparts prior to sampling. We evaluated the effectiveness of the design through power analysis and found that power to detect differences in aquatic invertebrate taxa richness was highest when sites were paired and terrain type was included as a factor in the analysis. Precision of the estimated difference in mean richness was nearly doubled using the terrain-based, paired site design in comparison to other evaluated designs. Use of this method allowed us to sample stream communities representative of park-wide forest conditions while effectively controlling for landscape variability.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Environmental Monitoring and Assessment","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1023/A:1015530712600","issn":"01676369","usgsCitation":"Young, J., Smith, D., Snyder, C., and Lemarie, D.P., 2002, A terrain-based paired-site sampling design to assess biodiversity losses from eastern hemlock decline: Environmental Monitoring and Assessment, v. 76, no. 2, p. 167-183, https://doi.org/10.1023/A:1015530712600.","startPage":"167","endPage":"183","numberOfPages":"17","costCenters":[],"links":[{"id":207865,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1023/A:1015530712600"},{"id":233121,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"76","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059e5f6e4b0c8380cd47069","contributors":{"authors":[{"text":"Young, J.A. 0000-0002-4500-3673","orcid":"https://orcid.org/0000-0002-4500-3673","contributorId":37674,"corporation":false,"usgs":true,"family":"Young","given":"J.A.","affiliations":[{"id":365,"text":"Leetown Science Center","active":true,"usgs":true}],"preferred":false,"id":401389,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Smith, D.

We found that beach morphology and wave energy interacted with density of spawning females to explain variation in the density and distribution of eggs and larvae. For example, the quantity of eggs in surface sediment (i.e., eggs that are potentially available to foraging shorebirds) was associated with the density of spawning females, beach morphology, and wave energy. The association between beach morphology and live eggs in surface sediment was strong especially in late May (Percent Reduction in Error = 86% from regression tree model) where egg density was an order of magnitude higher on beaches <15 m wide (3.38*105 m-2; 90% CI: 2.29*105, 4.47*105) compared to wider beaches (1.49*104 m-2; 90% CI: 4.47*103, 2.53*104). Results also indicate that, among bay-front beaches, horseshoe crabs prefer to spawn on narrow beaches, possibly because of reduced wave energy. At peak periods of spawning activity, density of spawning females was inversely related to foreshore width on mid-latitude beaches within Delaware Bay (t = -2.68, 7 df, p = 0.03). Because the distribution of eggs across the foreshore varied with beach morphology and widened as the spawning season progressed, methods used to sample eggs need to be robust to variation in beach morphology and applicable regardless of when the samples are taken. Because beach morphology and wave energy were associated with the quantity of eggs in surface sediment, certain beach types may be critical to the conservation of shorebird foraging habitat.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Coastal Research","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","issn":"07490208","usgsCitation":"Smith, D., Pooler, P., Loveland, R., Botton, M., Michels, S., Weber, R., and Carter, D.B., 2002, Horseshoe crab (Limulus polyphemus) reproductive activity on Delaware Bay beaches: Interactions with beach characteristics: Journal of Coastal Research, v. 18, no. 4, p. 730-740.","startPage":"730","endPage":"740","numberOfPages":"11","costCenters":[],"links":[{"id":231776,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"18","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a322ae4b0c8380cd5e594","contributors":{"authors":[{"text":"Smith, D.

Water and sediment collected from near the historic Heddleston mining district contained the highest concentrations of most trace elements in the basin.

Downstream on the headwaters area, water and bed sediment metal concentrations declined sharply.

The area of the proposed McDonald gold deposit near the confluence of the Landers Fork with the Blackfoot River was not contributing anomalous concentrations of naturally-occurring dissolved and bed-sediment metals into the basin.</span></p>","language":"English","publisher":"Springer Link","doi":"10.1007/s102300200033","usgsCitation":"Nagorski, S.A., Moore, J.N., and Smith, D., 2002, Distribution of metals in water and bed sediment in a mineral-rich watershed, Montana, USA: Mine Water and the Environment, v. 21, no. 3, p. 121-136, https://doi.org/10.1007/s102300200033.","productDescription":"16 p.","startPage":"121","endPage":"136","numberOfPages":"16","costCenters":[{"id":218,"text":"Denver Federal Center","active":false,"usgs":true}],"links":[{"id":231795,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.er.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Montana","otherGeospatial":"Blackfoot River","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -114.01611328125,\n              46.255846818480315\n            ],\n            [\n              -112.03857421875,\n              46.255846818480315\n            ],\n            [\n              -112.03857421875,\n              47.39834920035926\n            ],\n            [\n              -114.01611328125,\n              47.39834920035926\n            ],\n            [\n              -114.01611328125,\n              46.255846818480315\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"21","issue":"3","noUsgsAuthors":false,"publicationDate":"2014-04-12","publicationStatus":"PW","scienceBaseUri":"505a02e2e4b0c8380cd50241","contributors":{"authors":[{"text":"Nagorski, Sonia A.","contributorId":32940,"corporation":false,"usgs":true,"family":"Nagorski","given":"Sonia","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":399838,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Moore, Johnnie N","contributorId":289527,"corporation":false,"usgs":false,"family":"Moore","given":"Johnnie","email":"","middleInitial":"N","affiliations":[{"id":62170,"text":"Group for Quantitative Study of Snow and Ice, Department of Geosciences, University of Montana, Missoula, MT, United States","active":true,"usgs":false}],"preferred":false,"id":399837,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Smith, David B. 0000-0001-8396-9105 dsmith@usgs.gov","orcid":"https://orcid.org/0000-0001-8396-9105","contributorId":1274,"corporation":false,"usgs":true,"family":"Smith","given":"David B.","email":"dsmith@usgs.gov","affiliations":[{"id":218,"text":"Denver Federal Center","active":false,"usgs":true}],"preferred":false,"id":399836,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

Hemlock forests throughout eastern North America have been declining because of the hemlock woolly adelgid, an exotic insect pest. We found aquatic invertebrate community structure to be strongly correlated with forest composition. Streams draining hemlock forests supported significantly more total taxa than streams draining mixed hardwood forests, and over 8% of the taxa were strongly associated with hemlock. In addition, invertebrate taxa were more evenly distributed (i.e., higher Simpson's evenness values) in hemlock-drained streams. In contrast, the number of rare species and total densities were significantly lower in streams draining hemlock, suggesting that diversity differences observed between forest types were not related to stochastic factors associated with sampling and that streams draining mixed hardwood forests may be more productive. Analysis of stream habitat data indicated that streams draining hemlock forests had more stable thermal and hydrologic regimes. Our findings suggest that hemlock decline may result in long-term changes in headwater ecosystems leading to reductions in both within-stream (i.e., alpha) and park-wide (i.e., gamma) benthic community diversity.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Canadian Journal of Fisheries and Aquatic Sciences","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1139/f02-003","issn":"0706652X","usgsCitation":"Snyder, C., Young, J., Lemarie, D.P., and Smith, D., 2002, Influence of eastern hemlock (Tsuga canadensis) forests on aquatic invertebrate assemblages in headwater streams: Canadian Journal of Fisheries and Aquatic Sciences, v. 59, no. 2, p. 262-275, https://doi.org/10.1139/f02-003.","startPage":"262","endPage":"275","numberOfPages":"14","costCenters":[],"links":[{"id":232963,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":207766,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1139/f02-003"}],"volume":"59","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a3b2ce4b0c8380cd622bf","contributors":{"authors":[{"text":"Snyder, C.D.","contributorId":73540,"corporation":false,"usgs":true,"family":"Snyder","given":"C.D.","email":"","affiliations":[],"preferred":false,"id":402732,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Young, J.A. 0000-0002-4500-3673","orcid":"https://orcid.org/0000-0002-4500-3673","contributorId":37674,"corporation":false,"usgs":true,"family":"Young","given":"J.A.","affiliations":[{"id":365,"text":"Leetown Science Center","active":true,"usgs":true}],"preferred":false,"id":402730,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Lemarie, D.

An important part of the development of the DBOR tool is data analysis and visualization, with the aim of making the software graphical user interface (GUI) intuitive and easy to use. The DBOR software system consists of a suite of signal and image processing routines written in Research Systems' Interactive Data Language (IDL). The software also serves as a front-end to many widely accepted Colorado School of Mines Center for Wave Phenomena (CWP) Seismic UNIX (SU) algorithms (Cohen and Stockwell, 2001). Although the SU collection runs natively in a UNIX environment, our system seamlessly emulates a UNIX session within a widely used PC operating system (MicroSoft Windows) using GNU tools (Noer, 1998). Examples are presented of laboratory data acquired with the prototype tool from two different experimental settings. The first experiment imaged plastic pipes in a macro-scale sand tank. The second experiment monitored the progress of an invasion front resulting from oil injection. Finally, challenges to further development and planned future work are discussed.","largerWorkTitle":"Proceedings of SPIE - The International Society for Optical Engineering","conferenceTitle":"9th International Conference on Ground Penetrating Radar","conferenceDate":"29 April 2002 through 2 May 2002","conferenceLocation":"Santa Barbara, CA","language":"English","doi":"10.1117/12.462230","issn":"0277786X","usgsCitation":"Smith, D., and Brown, P., 2002, Advances in directional borehole radar data analysis and visualization, <i>in</i> Proceedings of SPIE - The International Society for Optical Engineering, v. 4758, Santa Barbara, CA, 29 April 2002 through 2 May 2002, p. 251-255, https://doi.org/10.1117/12.462230.","startPage":"251","endPage":"255","numberOfPages":"5","costCenters":[],"links":[{"id":209370,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1117/12.462230"},{"id":235721,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"4758","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059e703e4b0c8380cd477c8","contributors":{"authors":[{"text":"Smith, D.V.G.","contributorId":57249,"corporation":false,"usgs":true,"family":"Smith","given":"D.V.G.","email":"","affiliations":[],"preferred":false,"id":403877,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Brown, P.J.

The risk is low even if worst-case conditions are considered ? no containment and remediation of on-base contamination. The evaluation also shows that future saltwater encroachment of aquifers below sea level may be possible, but this determination has considerable uncertainty associated with it. The potential effects on the ground-water flow system resulting from four hypothetical ground-water pumping alternatives were considered, including no change in 1995 pumping rates, doubling the rates, and 2020 rates estimated from population projections with two different pumping distributions. All but a continuation of 1995 pumping rates demonstrate the possibility of future saltwater encroachment in the Sea-level aquifer on Naval Submarine Base Bangor. The amount of time it would take for encroachment to occur is unknown. For all pumping alternatives, future saltwater encroachment in the Sea-level aquifer also may be possible along Puget Sound east and southeast of the base. Future saltwater encroachment in the Deep aquifer also may be possible throughout large parts of the study area. Projections of saltwater encroachment are least certain outside the boundaries of Naval Submarine Base Bangor. The potential effects of the ground-water pumping alternatives were evaluated by simulating the ground-water flow system with a three-dimensional uniform-density ground-water flow model. The model was calibrated by trial-and-error by minimizing differences between simulated and measured or estimated variables. These included water levels from prior to January 17, 1977 (termed 'predevelopment'), water-level drawdowns since predevelopment until April 15, 1995, ground-water discharge to streams in water year 1995, and residence times of ground water in different parts of the flow system that were estimated in a separate but related study. Large amounts of ground water were pumped from 1977 through 1980 from the Sea-level aquifer on Naval Submarine Base Bangor to enable the construction of an off-shore drydock. Records of the flow-system responses to the applied stresses were used to help calibrate the model. Errors in the calibrated model were significant. The poor agreement between simulated and measured values could be improved by making many local changes to hydraulic parameters but these changes were not supported by other data. Model errors may have resulted in errors in the simulated effects of ground-water pumping alternatives.","language":"ENGLISH","doi":"10.3133/wri024261","usgsCitation":"Heeswijk, M.V., and Smith, D.T., 2002, Simulation of the ground-water flow system at Naval Submarine Base Bangor and vicinity, Kitsap County, Washington: U.S. Geological Survey Water-Resources Investigations Report 2002-4261, 153 p., https://doi.org/10.3133/wri024261.","productDescription":"153 p.","costCenters":[],"links":[{"id":3713,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.water.usgs.gov/wri024261/","linkFileType":{"id":5,"text":"html"}},{"id":168062,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4afee4b07f02db697795","contributors":{"authors":[{"text":"Heeswijk, Marijke van","contributorId":37201,"corporation":false,"usgs":true,"family":"Heeswijk","given":"Marijke","email":"","middleInitial":"van","affiliations":[],"preferred":false,"id":230101,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Smith, Daniel T.","contributorId":11878,"corporation":false,"usgs":true,"family":"Smith","given":"Daniel","email":"","middleInitial":"T.","affiliations":[],"preferred":false,"id":230100,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

We\r\ncollected samples also from Hogum Creek, a tributary to the Blackfoot, from Copper\r\nCreek, a tributary to the Landers Fork, and from ground water seeps contributing to the\r\nflow along the Landers Fork. To better define the physical dynamics of the hydrologic\r\nsystem and to determine geochemical loads, we measured streamflow at all the sites where\r\nwe took samples for water quality analysis. The Upper Blackfoot River, which drains\r\nhistoric mines ca. 20 Km upstream of the study area, had higher trace metal concentrations\r\nthan did the Landers Fork, which drains the pristine Scapegoat Wilderness area. In both\r\nrivers, many of the major elements were inversely related to streamflow, and at some sites,\r\nseveral show a hysteresis effect in which the concentrations were lower on the rising limb\r\nof the hydrograph than on the falling limb. However, many of the trace elements followed\r\nfar more irregular trends, especially in the Blackfoot River. Elements such as As, Cu, Fe,\r\nMn, S, and Zn exhibited complex and variable temporal patterns, which included almost no\r\nresponse to streamflow differences, increased concentrations following a summer storm\r\nand at the start of snowmelt in the spring, and/or increased concentrations throughout the\r\ncourse of spring runoff. In summary, complex interactions between the timing and\r\nmagnitude of streamflow with physical and chemical processes within the watershed\r\nappeared to greatly influence the geochemistry at the sites, and streamflow values alone\r\nwere not good predictors of solute concentrations in the rivers.","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/ofr0159","usgsCitation":"Nagorski, S.A., Moore, J.N., and Smith, D., 2001, Geochemical baseline studies and relations between water quality and streamflow in the Upper Blackfoot watershed, Montana: Data for July 1997-December 1998: U.S. Geological Survey Open-File Report 2001-59, 99 p., https://doi.org/10.3133/ofr0159.","productDescription":"99 p.","costCenters":[],"links":[{"id":406783,"rank":2,"type":{"id":36,"text":"NGMDB Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_37217.htm","linkFileType":{"id":5,"text":"html"}},{"id":2794,"rank":3,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/of/2001/ofr-01-0059/","linkFileType":{"id":5,"text":"html"}},{"id":161031,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"}],"country":"United States","state":"Montana","otherGeospatial":"Upper Blackfoot watershed","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -112.61,\n              46.949\n            ],\n            [\n              -112.498,\n              46.949\n            ],\n            [\n              -112.498,\n              47.017\n            ],\n            [\n              -112.61,\n              47.017\n            ],\n            [\n              -112.61,\n              46.949\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b24e4b07f02db6ae61c","contributors":{"authors":[{"text":"Nagorski, Sonia A.","contributorId":32940,"corporation":false,"usgs":true,"family":"Nagorski","given":"Sonia","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":205368,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Moore, Johnnie N.","contributorId":102532,"corporation":false,"usgs":true,"family":"Moore","given":"Johnnie","email":"","middleInitial":"N.","affiliations":[],"preferred":false,"id":205369,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Smith, David B. 0000-0001-8396-9105 dsmith@usgs.gov","orcid":"https://orcid.org/0000-0001-8396-9105","contributorId":1274,"corporation":false,"usgs":true,"family":"Smith","given":"David B.","email":"dsmith@usgs.gov","affiliations":[{"id":218,"text":"Denver Federal Center","active":false,"usgs":true}],"preferred":false,"id":205367,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

The goal of the Pea Ridge study is to compare the Middle Proterozoic iron deposits of Missouri with the Middle Proterozoic Olympic Dam deposit and similar deposits of the Stuart Shelf, South Australia. This effort developed from work by Sims and others (1987), who recognized the many similarities between the St. Francois terrane in southeastern Missouri and the Stuart Shelf and also the potential for Olympic Dam-type deposits in the Middle Proterozoic granite-rhyolite terranes of the Midcontinent. Detailed descriptions of the map units are given in Nuelle and others (1992). Results of stable-isotope, fluid-inclusion, and traceelement studies that focus on the origin of the ore deposit are presented in Day and others&nbsp;(1991, 1992, and 1993), Sidder and others (1991, 1993a, b), and Cordell and others (1993).</p>","language":"English","doi":"10.3133/mf2353","usgsCitation":"Seeger, C., Nuelle, L.M., Sidder, G., Marikos, M., and Smith, D.C., 2001, Geologic maps and cross sections of mine levels at the Pea Ridge iron mine, Washington County, Missouri: U.S. Geological Survey Miscellaneous Field Studies Map 2353, 5 sheets, https://doi.org/10.3133/mf2353.","productDescription":"5 sheets","costCenters":[],"links":[{"id":186818,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"},{"id":6047,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/mf/2001/mf-2353/","linkFileType":{"id":5,"text":"html"}},{"id":110178,"rank":700,"type":{"id":15,"text":"Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_37357.htm","linkFileType":{"id":5,"text":"html"},"description":"37357"}],"scale":"24000","country":"United States","state":"Missouri","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -91.05055555555555,38.11694444444444 ], [ -91.05055555555555,38.13361111111111 ], [ -91.03333333333333,38.13361111111111 ], [ -91.03333333333333,38.11694444444444 ], [ -91.05055555555555,38.11694444444444 ] ] ] } } ] }","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4ae1e4b07f02db688642","contributors":{"authors":[{"text":"Seeger, C.M.","contributorId":55484,"corporation":false,"usgs":true,"family":"Seeger","given":"C.M.","email":"","affiliations":[],"preferred":false,"id":265756,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Nuelle, L.
