We examined home range size and habitat use of nine female northern myotis (Myotis septentrionalis) within an intensively managed forest in the central Appalachians of West Virginia. Using the 95% adaptive kernel method, we calculated a mean home range of 65 ha. Northern myotis used recent diameter-limit harvests and road corridors more than expected based on availability of these habitats. Intact forest stands and more open deferment harvested stands were used less than expected based on the availability of these habitats, although intact forest stands still constituted the overall majority of habitat used. Partial timber harvests that leave a relatively closed canopy appear to promote or improve northern myotis foraging habitat in heavily forested landscapes. However, the long-term ecological impacts on bats and other biota from this silviculturally unacceptable practice are unclear.

All of these variables except lake ice-out date showed significant temporal trends during the 20th century. Average ice thickness around 28 February decreased by about 23 cm from 1912 to 2001. Over the period 1900 to 1999, winter air temperature increased by 1.7??C and HDD decreased by about 7.5%. Final ice-out date on the Piscataquis River occurred earlier (advanced), by 0.21 days yr-1 over the period 1931 to 2002, and the SCVD advanced by 0.11 days yr-1 over the period 1903 to 2001. Ice thickness was significantly correlated (P-value < 0.01) with winter air temperature, HDD, river ice-out, and SCVD.

Some of these pollutants, such as polychlorinated biphenyls and dioxins, are known to induce expression of the CYP1A subfamily of genes. We applied a highly sensitive technique, quantitative reverse transcription-polymerase chain reaction (RT-PCR), for measuring the levels of CYP1A induction in Atlantic salmon. This assay was used to detect patterns of CYP1A mRNA levels, a direct measure of CYP1A expression, in Atlantic salmon exposed to pollutants under both laboratory and field conditions. Two groups of salmon were acclimated to 11 and 17??C, respectively. Each subject then received an intraperitoneal injection (50 mg kg-1) of either ??-naphthoflavone (BNF) in corn oil (10 mg BNF ml-1 corn oil) or corn oil alone. After 48 h, salmon gill, kidney, liver, and brain were collected for RNA isolation and analysis. All tissues showed induction of CYP1A by BNF. The highest base level of CYP1A expression (2.56??1010 molecules/??g RNA) was found in gill tissue. Kidney had the highest mean induction at five orders of magnitude while gill tissue showed the lowest mean induction at two orders of magnitude. The quantitative RT-PCR was also applied to salmon sampled from two streams in Massachusetts, USA. Salmon liver and gill tissue sampled from Millers River (South Royalston, Worcester County), known to contain polychlorinated biphenyls (PCBs), showed on average a two orders of magnitude induction over those collected from a stream with no known contamination (Fourmile Brook, Northfield, Franklin County). Overall, the data show CYP1A exists and is inducible in Atlantic salmon gill, brain, kidney, and liver tissue. In addition, the results obtained demonstrate that quantitative PCR analysis of CYP1A expression is useful in studying ecotoxicity in populations of Atlantic salmon in the wild. ?? 2003 Elsevier Science B.V.

We evaluated performance of landscape models for wolverines within their historical range at 2 scales in the interior Northwest based on recent observations (n = 421) from Washington, Oregon, Idaho, and Montana. At the subbasin scale, simple overlays of habitat and road-density classes were effective in predicting observations of wolverines. At the watershed scale, we used a Bayesian belief network model to provide spatially explicit estimates of relative habitat capability. The model has 3 inputs: amount of habitat, human population density, and road density. At both scales, the best models revealed strong correspondence between means of predicted counts of wolverines and means of observed counts (P < 0.001). Our results can be used to guide regional conservation planning for this elusive animal.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Mammalogy","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1644/1545-1542(2003)084<0092:EOLMFW>2.0.CO;2","issn":"00222372","usgsCitation":"Rowland, M., Wisdom, M., Johnson, D.H., Wales, B., Copeland, J., and Edelmann, F., 2003, Evaluation of landscape models for wolverines in the interior Northwest, United States of America: Journal of Mammalogy, v. 84, no. 1, p. 92-105, https://doi.org/10.1644/1545-1542(2003)084<0092:EOLMFW>2.0.CO;2.","productDescription":"14 p.","startPage":"92","endPage":"105","costCenters":[{"id":480,"text":"Northern Prairie Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":487519,"rank":10000,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1644/1545-1542(2003)084<0092:eolmfw>2.0.co;2","text":"Publisher Index Page"},{"id":234550,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":208659,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1644/1545-1542(2003)084<0092:EOLMFW>2.0.CO;2"}],"volume":"84","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a0c8ee4b0c8380cd52bcb","contributors":{"authors":[{"text":"Rowland, M.M.","contributorId":30941,"corporation":false,"usgs":true,"family":"Rowland","given":"M.M.","email":"","affiliations":[],"preferred":false,"id":407599,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Wisdom, M.J.","contributorId":102830,"corporation":false,"usgs":true,"family":"Wisdom","given":"M.J.","email":"","affiliations":[],"preferred":false,"id":407602,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Johnson, Douglas H. 0000-0002-7778-6641","orcid":"https://orcid.org/0000-0002-7778-6641","contributorId":70327,"corporation":false,"usgs":true,"family":"Johnson","given":"Douglas","email":"","middleInitial":"H.","affiliations":[],"preferred":false,"id":407601,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Wales, B.C.","contributorId":17942,"corporation":false,"usgs":true,"family":"Wales","given":"B.C.","email":"","affiliations":[],"preferred":false,"id":407598,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Copeland, J.P.","contributorId":106055,"corporation":false,"usgs":true,"family":"Copeland","given":"J.P.","email":"","affiliations":[],"preferred":false,"id":407603,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Edelmann, F.B.","contributorId":56597,"corporation":false,"usgs":true,"family":"Edelmann","given":"F.B.","email":"","affiliations":[],"preferred":false,"id":407600,"contributorType":{"id":1,"text":"Authors"},"rank":6}]}} ,{"id":70026031,"text":"70026031 - 2003 - Impact damage to dinocysts from the Late Eocene Chesapeake Bay event","interactions":[],"lastModifiedDate":"2021-08-22T18:29:52.773325","indexId":"70026031","displayToPublicDate":"2003-01-01T00:00:00","publicationYear":"2003","noYear":false,"publicationType":{"id":2,"text":"Article"},"publicationSubtype":{"id":10,"text":"Journal Article"},"seriesTitle":{"id":3000,"text":"Palaios","active":true,"publicationSubtype":{"id":10}},"title":"Impact damage to dinocysts from the Late Eocene Chesapeake Bay event","docAbstract":"The Chesapeake Bay impact structure, formed by a comet or meteorite that struck the Virginia continental shelf about 35.5 million years ago, is the focus of an extensive coring project by the U.S. Geological Survey and its cooperators. Organic-walled dinocysts recovered from impact-generated deposits in a deep core inside the 85-90 km-wide crater include welded organic clumps and fused, partially melted and bubbled dinocysts unlike any previously observed. Other observed damage to dinocysts consists of breakage, pitting, and folding in various combinations. The entire marine Cretaceous, Paleocene, and Eocene section that was once present at the site has been excavated and redeposited under extreme conditions that include shock, heat, collapse, tsunamis, and airfall. The preserved dinocysts reflect these conditions and, as products of a known impact, may serve as guides for recognizing impact-related deposits elsewhere. Features that are not unique to impacts, such as breakage and folding, may offer new insights into crater-history studies in general, and to the history of the Chesapeake Bay impact structure in particular. Impact-damaged dinocysts also are found sporadically in post-impact deposits and add to the story of continuing erosion and faulting of crater material.","language":"English","publisher":"Society for Sedimentary Geology","doi":"10.1669/0883-1351(2003)018<0275:IDTDFT>2.0.CO;2","issn":"08831351","usgsCitation":"Edwards, L.E., and Powars, D.S., 2003, Impact damage to dinocysts from the Late Eocene Chesapeake Bay event: Palaios, v. 18, no. 3, p. 275-285, https://doi.org/10.1669/0883-1351(2003)018<0275:IDTDFT>2.0.CO;2.","productDescription":"11 p.","startPage":"275","endPage":"285","numberOfPages":"11","costCenters":[{"id":241,"text":"Eastern Energy Resources Science Center","active":true,"usgs":true},{"id":40020,"text":"Florence Bascom Geoscience Center","active":true,"usgs":true}],"links":[{"id":388325,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","otherGeospatial":"Chesapeake Bay","geographicExtents":"{\n \"type\": \"FeatureCollection\",\n \"features\": [\n {\n \"type\": \"Feature\",\n \"properties\": {},\n \"geometry\": {\n \"type\": \"Polygon\",\n \"coordinates\": [\n [\n [\n -76.09130859375,\n 39.60145584096999\n ],\n [\n -76.5911865234375,\n 39.27053717095511\n ],\n [\n -76.6021728515625,\n 38.89958342598271\n ],\n [\n -76.6845703125,\n 38.298559092254344\n ],\n [\n -77.069091796875,\n 38.363195134453846\n ],\n [\n -76.8438720703125,\n 38.14751758025121\n ],\n [\n -76.3055419921875,\n 37.913867495923746\n ],\n [\n -76.37695312499999,\n 37.62728430268013\n ],\n [\n -76.37695312499999,\n 37.36142550190517\n ],\n [\n -76.46484375,\n 37.41816326969145\n ],\n [\n -76.475830078125,\n 37.16907157713011\n ],\n [\n -76.2890625,\n 37.02448395075965\n ],\n [\n -76.1187744140625,\n 36.91915611148194\n ],\n [\n -75.69030761718749,\n 37.84883250647402\n ],\n [\n -75.8551025390625,\n 37.97884504049713\n ],\n [\n -76.278076171875,\n 38.40194908237822\n ],\n [\n -76.102294921875,\n 38.66406704456943\n ],\n [\n -76.17919921875,\n 39.031986028740086\n ],\n [\n -76.2725830078125,\n 39.16839998800286\n ],\n [\n -75.89355468749999,\n 39.410733055084954\n ],\n [\n -75.8331298828125,\n 39.554883059924016\n ],\n [\n -76.09130859375,\n 39.60145584096999\n ]\n ]\n ]\n }\n }\n ]\n}","volume":"18","issue":"3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a38ade4b0c8380cd61656","contributors":{"authors":[{"text":"Edwards, Lucy E. 0000-0003-4075-3317 leedward@usgs.gov","orcid":"https://orcid.org/0000-0003-4075-3317","contributorId":2647,"corporation":false,"usgs":true,"family":"Edwards","given":"Lucy","email":"leedward@usgs.gov","middleInitial":"E.","affiliations":[{"id":243,"text":"Eastern Geology and Paleoclimate Science Center","active":true,"usgs":true},{"id":40020,"text":"Florence Bascom Geoscience Center","active":true,"usgs":true}],"preferred":true,"id":407596,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Powars, David S. 0000-0002-6787-8964 dspowars@usgs.gov","orcid":"https://orcid.org/0000-0002-6787-8964","contributorId":1181,"corporation":false,"usgs":true,"family":"Powars","given":"David","email":"dspowars@usgs.gov","middleInitial":"S.","affiliations":[{"id":243,"text":"Eastern Geology and Paleoclimate Science Center","active":true,"usgs":true},{"id":40020,"text":"Florence Bascom Geoscience Center","active":true,"usgs":true}],"preferred":true,"id":407597,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}} ,{"id":70026030,"text":"70026030 - 2003 - Ice cover, landscape setting, and geological framework of Lake Vostok, East Antarctica","interactions":[],"lastModifiedDate":"2012-03-12T17:20:21","indexId":"70026030","displayToPublicDate":"2003-01-01T00:00:00","publicationYear":"2003","noYear":false,"publicationType":{"id":2,"text":"Article"},"publicationSubtype":{"id":10,"text":"Journal Article"},"seriesTitle":{"id":1427,"text":"Earth and Planetary Science Letters","active":true,"publicationSubtype":{"id":10}},"title":"Ice cover, landscape setting, and geological framework of Lake Vostok, East Antarctica","docAbstract":"Lake Vostok, located beneath more than 4 km of ice in the middle of East Antarctica, is a unique subglacial habitat and may contain microorganisms with distinct adaptations to such an extreme environment. Melting and freezing at the base of the ice sheet, which slowly flows across the lake, controls the flux of water, biota and sediment particles through the lake. The influx of thermal energy, however, is limited to contributions from below. Thus the geological origin of Lake Vostok is a critical boundary condition for the subglacial ecosystem. We present the first comprehensive maps of ice surface, ice thickness and subglacial topography around Lake Vostok. The ice flow across the lake and the landscape setting are closely linked to the geological origin of Lake Vostok. Our data show that Lake Vostok is located along a major geological boundary. Magnetic and gravity data are distinct east and west of the lake, as is the roughness of the subglacial topography. The physiographic setting of the lake has important consequences for the ice flow and thus the melting and freezing pattern and the lake's circulation. Lake Vostok is a tectonically controlled subglacial lake. The tectonic processes provided the space for a unique habitat and recent minor tectonic activity could have the potential to introduce small, but significant amounts of thermal energy into the lake. ?? 2002 Elsevier Science B.V.

A discrete fracture network model calculated fluid flux through volumes of various scales to determine scale effects, directional bulk permeability, and connectivity. The mean directional permeabilities varied by less than a factor of 6, with the northwest-southeast direction (face cleat direction) as the most conductive. Northwest southeast directed hydrofracture simulations increased permeability in all directions except the northeast-southwest, although the permeability increase was not more than a factor of 3. Cluster analysis showed that the simulated cleat network was very well connected at all simulated scales. For thick coals, the entire cleat network formed one compartment, whereas thin coals formed several compartments. Convex hulls of the compartments confirmed that the directional bulk permeability was nearly isotropic. Volumetric calculations of the Ferron coal indicated that all the water produced to date can be accounted for from the coal cleat porosity system and does not depend on contributions of water from contiguous units.Flow paths, determined from porous media modeling from recharge to discharge, indicate that the three coalbed gas (CBG) fields assessed in this study could have different groundwater chemical compositions as confirmed by geochemical data. Simulated water production from 185 wells from 1993 to 1998 showed that in 1998 the maximum head drawdown from the Drunkards Wash field was more than 365 m, and the cone of depression extended to within a short distance of the Ferron outcrop. Maximum drawdown in the Helper field was 120 m, and the maximum drawdown in the Buzzards Bench field was just over 60 m. The cone of depression for the Helper field was half the size of the Drunkards Wash field, and the cone of depression for the Buzzards Bench field was limited to just outside the field unit. Water budget calculations from the simulation indicate that none of the stream flows are affected by coalbed gas associated water production. ?? 2003 Elsevier B.V.

A preliminary investigation of benthic microbial Hg cycling was conducted in surface sediment (0–4 cm) collected from one salt-marsh and three open-water sites. A deeper profile (0–26 cm) was evaluated at one of the open-water locations. Radiolabeled model Hg-compounds were used to measure rates of both methylmercury (MeHg) production and degradation by bacteria. While all sites and depths had similar total-Hg concentrations (0.3–0.6 ppm), and geochemical signatures of mining debris (as εNd, range: –3.08 to –4.37), in-situ MeHg was highest in the marsh (5.4±3.5 ppb) and ≤0.7 ppb in all open-water sites. Microbial MeHg production (potential rate) in 0–4 surface sediments was also highest in the marsh (3.1 ng g–1 wet sediment day–1) and below detection (<0.06 ng g–1 wet sediment day–1) in open-water locations. The marsh exhibited a methylation/demethylation (M/D) ratio more than 25× that of all open-water locations. Only below the surface 0–4-cm horizon was significant MeHg production potential evident in the open-water sediment profile (0.2–1.1 ng g–1 wet sediment day–1). In-situ Hg methylation rates, calculated from radiotracer rate constants, and in-situ inorganic Hg(II) concentrations compared well with potential rates. However, similarly calculated in-situ rates of MeHg degradation were much lower than potential rates. These preliminary data indicate that wetlands surrounding San Pablo Bay represent important zones of MeHg production, more so than similarly Hg-contaminated adjacent open-water areas. This has significant implications for this and other Hg-impacted systems, where wetland expansion is currently planned.

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.

A relationship within the family Triploporellaceae is indicated by the whorled arrangement of the laterals and the absence of gametophores on mature specimens. A compilation of occurrence data suggests that noncalcified dasyclads, as a whole, were more abundant and diverse during the Ordovician and Silurian than at any other time in their history. The heterocladous thallus architecture of this alga adds to a wide range of morphological variation documented among Ordovician and Silurian dasyclads, the sum of which indicates that Dasycladales underwent a significant evolutionary radiation during the early Paleozoic.

Nutrient levels were significantly different among the native, ecotone, and exotic-derived soils. NO3, P, K, and Na all increased as the cover of halogeton increased. Only Ca was highest in the winterfat area. A principal components analysis, conducted separately for water-soluble and exchangeable cations, revealed clear separation between halogeton- and winterfat-derived soils. The diversity of soil bacteria was highest in the exotic, intermediate in the ecotone, and lowest in the native community. Although further studies are necessary, our results offer evidence that invasion by halogeton alters soil chemistry and soil ecology, possibly creating conditions that favor halogeton over native plants.

Engineering constraints important to the selection included (1) latitude (10°N–15°S) for maximum solar power, (2) elevation (less than −1.3 km) for sufficient atmosphere to slow the lander, (3) low horizontal winds, shear, and turbulence in the last few kilometers to minimize horizontal velocity, (4) low 10‐m‐scale slopes to reduce airbag spin‐up and bounce, (5) moderate rock abundance to reduce abrasion or strokeout of the airbags, and (6) a radar‐reflective, load‐bearing, and trafficable surface safe for landing and roving that is not dominated by fine‐grained dust. The evaluation of sites utilized existing as well as targeted orbital information acquired from the Mars Global Surveyor and Mars Odyssey. Three of the final four landing sites show strong evidence for surface processes involving water and appear capable of addressing the science objectives of the missions, which are to determine the aqueous, climatic, and geologic history of sites on Mars where conditions may have been favorable to the preservation of evidence of possible prebiotic or biotic processes. The evaluation of science criteria placed Meridiani and Gusev as the highest‐priority sites. The evaluation of the three most critical safety criteria (10‐m‐scale slopes, rocks, and winds) and landing simulation results indicated that Meridiani and Elysium Planitia are the safest sites, followed by Gusev and Isidis Planitia.

These measurements and associated data were provided by a collection of instruments that included two 915 MHz wind profilers, two radio acoustic sounding systems, and two eddy correlation devices. The data from these devices were available through the Atmospheric Boundary Layer Experiment (ABLE) database operated by Argonne National Laboratory. A signal processing procedure outlined by Angevine et al. was adapted and further built upon to derive vertical velocity variance, w_pm???2, from 915 MHz wind profiler measurements in the mixed layer. The proposed procedure consisted of the application of a height-dependent signal-to-noise ratio (SNR) filter, removal of outliers plus and minus two standard deviations about the mean on the spectral width squared, and removal of the effects of beam broadening and vertical shearing of horizontal winds. The scatter associated with w_pm???2 was mainly affected by the choice of SNR filter cutoff values. Several different sets of cutoff values were considered, and the optimal one was selected which reduced the overall scatter on w_pm???2 and yet retained a sufficient number of data points to average. A similarity relationship of w_pm???2 versus height was established for the mixed layer on the basis of the available data. A strong link between the SNR and growth/decay phases of turbulence was identified. Thus, the mid to late afternoon hours, when strong surface heating occurred, were observed to produce the highest quality signals.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Hydrologic Engineering","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1061/(ASCE)1084-0699(2003)8:6(301)","issn":"10840699","usgsCitation":"Eng, K., Coulter, R., and Brutsaert, W., 2003, Vertical velocity variance in the mixed layer from radar wind profilers: Journal of Hydrologic Engineering, v. 8, no. 6, p. 301-307, https://doi.org/10.1061/(ASCE)1084-0699(2003)8:6(301).","startPage":"301","endPage":"307","numberOfPages":"7","costCenters":[],"links":[{"id":233073,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":207835,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1061/(ASCE)1084-0699(2003)8:6(301)"}],"volume":"8","issue":"6","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505bc24ae4b08c986b32aa4a","contributors":{"authors":[{"text":"Eng, K.","contributorId":51063,"corporation":false,"usgs":true,"family":"Eng","given":"K.","email":"","affiliations":[],"preferred":false,"id":402879,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Coulter, R.L.","contributorId":78913,"corporation":false,"usgs":true,"family":"Coulter","given":"R.L.","email":"","affiliations":[],"preferred":false,"id":402880,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Brutsaert, W.","contributorId":103445,"corporation":false,"usgs":true,"family":"Brutsaert","given":"W.","affiliations":[],"preferred":false,"id":402881,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}} ,{"id":70024908,"text":"70024908 - 2003 - Revised Landsat-5 TM radiometric calibration procedures and postcalibration dynamic ranges","interactions":[],"lastModifiedDate":"2017-04-10T10:33:21","indexId":"70024908","displayToPublicDate":"2003-01-01T00:00:00","publicationYear":"2003","noYear":false,"publicationType":{"id":2,"text":"Article"},"publicationSubtype":{"id":10,"text":"Journal Article"},"seriesTitle":{"id":1944,"text":"IEEE Transactions on Geoscience and Remote Sensing","active":true,"publicationSubtype":{"id":10}},"title":"Revised Landsat-5 TM radiometric calibration procedures and postcalibration dynamic ranges","docAbstract":"Effective May 5, 2003, Landsat-5 (L5) Thematic Mapper (TM) data processed and distributed by the U.S. Geological Survey (USGS) Earth Resources Observation System (EROS) Data Center (EDC) will be radiometrically calibrated using a new procedure and revised calibration parameters.

During a 50-year simulation, Wells Creek, a third-order cold water stream, had an estimated 1,164 events (i.e., one or more consecutive days of estimated sediment loading) and the Chippewa River, a fourth-order warm water stream, had 906 events of measurable suspended sediment. Sublethal thresholds were exceeded for 970 events and lethal levels for 194 events for brown trout in Wells Creek, whereas adult nonsalmonidis would have experienced sublethal levels for 923 events and lethal levels for 241 events. Sublethal levels were exceeded for 756 events and lethal thresholds were exceeded for 150 events in the Chippewa River. Nonsalmonids would have experienced 15 events of mortality between 0 and 20 percent in Wells Creek. In the Chippewa River, there were 35 events of mortality between 0 and 20 percent and one event in which mortality could have exceeded 20 percent. The Minnesota Pollution Control Agency has proposed listing stream reaches as being impaired for turbidity at 25 NTU, which is approximately 46 mg suspended sediment/l. We estimated that 46 mg/l would be exceeded approximately 30 days in a year (d/yr) in both systems. A TMDL of 46 mg SS/l may be too high to ensure that stream fishes are not negatively affected by suspended sediment. We recommend that an indicator incorporating the duration of exposure be applied.

Three types of mercury deposits occur in these belts: silica-carbonate, hot-spring, and Almaden. Mercury is also produced as a by-product from several types of gold-silver and massive sulfide deposits, which account for 5% of the world's production. Other types of mineral deposits can be enriched in mercury and mercury phases present are dependent on deposit type. During processing of mercury ores, secondary mercury phases form and accumulate in mine wastes. These phases are more soluble than cinnabar, the primary ore mineral, and cause mercury deposits to impact the environment more so than other types of ore deposits enriched in mercury. Release and transport of mercury from mine wastes occur primarily as mercury-enriched particles and colloids. Production from mercury deposits has decreased because of environmental concerns, but by-product production from other mercury-enriched mineral deposits remains important.","language":"English","publisher":"Springer","doi":"10.1007/s00254-002-0629-5","issn":"09430105","usgsCitation":"Rytuba, J.J., 2003, Mercury from mineral deposits and potential environmental impact: Environmental Geology, v. 43, no. 3, p. 326-338, https://doi.org/10.1007/s00254-002-0629-5.","productDescription":"13 p.","startPage":"326","endPage":"338","numberOfPages":"1","costCenters":[],"links":[{"id":234395,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"43","issue":"3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a5405e4b0c8380cd6ce6c","contributors":{"authors":[{"text":"Rytuba, J.

We tested a model that can help improve the consistency of electrofishing by allowing control over the amount of power that is transferred to the fish. The primary objective was to verify, under controlled laboratory conditions, whether the model adequately described fish immobilization responses elicited with various electrical settings over a range of water conductivities. We found that the model accurately described empirical observations over conductivities ranging from 12 to 1,030 ??S/cm for DC and various pulsed-DC settings. Because the model requires knowledge of a fish's effective conductivity, an attribute that is likely to vary according to species, size, temperature, and other variables, a second objective was to gather available estimates of the effective conductivity of fish to examine the magnitude of variation and to assess whether in practical applications a standard effective conductivity value for fish may be assumed. We found that applying a standard fish effective conductivity of 115 ??S/cm introduced relatively little error into the estimation of the peak power density required to immobilize fish with electrofishing. However, this standard was derived from few estimates of fish effective conductivity and a limited number of species; more estimates are needed to validate our working standard.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Transactions of the American Fisheries Society","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1577/T02-093","issn":"00028487","usgsCitation":"Miranda, L., and Dolan, C., 2003, Test of a Power Transfer Model for Standardized Electrofishing: Transactions of the American Fisheries Society, v. 132, no. 6, p. 1179-1185, https://doi.org/10.1577/T02-093.","startPage":"1179","endPage":"1185","numberOfPages":"7","costCenters":[],"links":[{"id":233072,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":207834,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1577/T02-093"}],"volume":"132","issue":"6","noUsgsAuthors":false,"publicationDate":"2011-01-09","publicationStatus":"PW","scienceBaseUri":"505ba59fe4b08c986b320b72","contributors":{"authors":[{"text":"Miranda, L.E.","contributorId":58406,"corporation":false,"usgs":true,"family":"Miranda","given":"L.E.","affiliations":[],"preferred":false,"id":402877,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Dolan, C.R.","contributorId":96870,"corporation":false,"usgs":true,"family":"Dolan","given":"C.R.","email":"","affiliations":[],"preferred":false,"id":402878,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}} ,{"id":70187730,"text":"70187730 - 2003 - Seabird tissue archival and monitoring project: Egg collections and analytical results 1999-2002","interactions":[],"lastModifiedDate":"2018-08-19T21:51:59","indexId":"70187730","displayToPublicDate":"2003-01-01T00:00:00","publicationYear":"2003","noYear":false,"publicationType":{"id":18,"text":"Report"},"publicationSubtype":{"id":1,"text":"Federal Government Series"},"subseriesTitle":"NIST 7029","title":"Seabird tissue archival and monitoring project: Egg collections and analytical results 1999-2002","docAbstract":"In 1998, the U.S. Geological Survey Biological Resources Division (USGS-BRD), the U.S. Fish and Wildlife Service (USFWS) Alaska Maritime National Wildlife Refuge (AMNWR), and the National Institute of Standards and Technology (NIST) began the Seabird Tissue Archival and Monitoring Project (STAMP) to collect and cryogenically bank tissues from seabirds in Alaska for future retrospective analysis of anthropogenic contaminants. The approach of STAMP was similar to that of the Alaska Marine Mammal Tissue Archival Project (AMMTAP). AMMTAP was started in 1987 by NIST and the National Oceanic and Atmospheric Administration (NOAA) as part of the Outer Continental Shelf Environmental Assessment Program sponsored by the Minerals Management Service. Presently sponsored by the USGS-BRD, AMMTAP continues its work as part of a larger national program, the Marine Mammal Health and Stranding Response Program. AMMTAP developed carefully designed sampling and specimen banking protocols. Since 1987, AMMTAP has collected tissues from marine mammals taken in Alaska Native subsistence hunts and has cryogenically banked these tissues at the NIST National Biomonitoring Specimen Bank (NBSB). Through its own analytical work and working in partnership with other researchers both within and outside Alaska, AMMTAP has helped to develop a substantial database on contaminants in Alaska marine mammals. In contrast, data and information is limited on contaminants in Alaska seabirds, which are similar to marine mammals in that they feed near the top of the food chain and have the potential for accumulating anthropogenic contaminants.
During its early planning stages, STAMP managers identified the seabird egg as the first tissue of choice for study by the project. There is a relatively long history of using bird eggs for environmental monitoring and for investigating the health status of bird populations. Since 1998, protocols for collecting and processing eggs, and cryogenically banking egg samples have been developed by STAMP (see York et al. 2001). Eggs are being collected on an annual basis for several species at nesting colonies throughout Alaska. Aliquots of these egg samples are being analyzed on a regular basis for persistent organic pollutants and mercury. Results of this work have been published in scientific journals (Christopher et al. 2002) and in conference proceedings (Kucklick et al. 2002; Vander Pol et al. 2002a, 2002b).
The intent of this report is to provide an up-to-date description of STAMP. The report contains the most recent egg collection inventory, analytical data, preliminary interpretations based on these data, and a discussion of possible future directions of the project.

However, the historic distribution of lynx in the Northeast is poorly understood. We used museum records, bibliographic records, and interviews to reconstruct the past distribution of lynx in Maine, which is at the current southern limit of the species' distribution in the eastern United States. We found a total of 118 records, representing at least 509 lynx in Maine. Lynx were observed throughout Maine, 1833–1912, with the exception of coastal areas. After 1913, lynx were most common in the forests of western and northern Maine, and absent to rare along the coast, but had not returned to southern Maine by 1999. Thirty-nine kittens representing at least 21 litters were distributed throughout northern and western Maine, 1864–1999. Populations apparently fluctuated, and in some years 200–300 lynx were harvested in Maine. Prior to the 1900s, lynx were much more widely distributed in the Northeast, ranging from Pennsylvania north into Quebec. Because Canada lynx have had a long presence in northern New England, and at times were relatively common, this species merits serious consideration in conservation planning in this region.

As early as December (age 0+ years), fish that later smolted at age 2+ years were significantly larger than fish that did not smolt at age 2+ years. In contrast, there were no mass differences at age 0+ years between fish that would mature or not at age 1+ years (October). The mass differences between smolts and non-smolts persisted until smolting, and differences between mature and immature fish first appeared in May (age 1+ years). Following September (age 1+ years), there was also a significant interaction between smolting and maturity. Previously mature and immature age 2+ year smolts were not significantly different in size, but immature age 2+ year non-smolts were much lighter than mature age 2+ year non-smolts. Based on mass differences, the apparent 'decision' to smolt occurred c. 5 months before (winter, age 0+ years) the decision to mature (late spring, age 1+ years). In addition to strong seasonal growth variation, sizes of freshwater Atlantic salmon were largely structured by the complex interaction between smolt-age and maturity. ?? 2003 The fisheries Society of the British Isles.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Fish Biology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1046/j.1095-8649.2003.00009.x","issn":"00221112","usgsCitation":"Letcher, B., and Gries, G., 2003, Effects of life history variation on size and growth in stream-dwelling Atlantic salmon: Journal of Fish Biology, v. 62, no. 1, p. 97-114, https://doi.org/10.1046/j.1095-8649.2003.00009.x.","startPage":"97","endPage":"114","numberOfPages":"18","costCenters":[],"links":[{"id":234773,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":208781,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1046/j.1095-8649.2003.00009.x"}],"volume":"62","issue":"1","noUsgsAuthors":false,"publicationDate":"2003-02-12","publicationStatus":"PW","scienceBaseUri":"505a0745e4b0c8380cd5160d","contributors":{"authors":[{"text":"Letcher, B.

If this is the case, the levels of these transporters should be high in chloride cells of seawater-acclimated fish. We therefore examined the influence of salinity on immunolocalization of Na +/K+-ATPase, NKCC and CFTR in the gills of the Hawaiian goby (Stenogobius hawaiiensis). Fish were acclimated to freshwater and 20??? and 30??? seawater for 10 days. Na+/K +-ATPase and NKCC were localized specifically to chloride cells and stained throughout most of the cell except for the nucleus and the most apical region, indicating a basolateral/tubular distribution. All Na+/K +-ATPase-positive chloride cells were also positive for NKCC in all salinities. Salinity caused a slight increase in chloride cell number and size and a slight decrease in staining intensity for Na+/K +-ATPase and NKCC, but the basic pattern of localization was not altered. Gill Na+/K+-ATPase activity was also not affected by salinity. CFTR was localized to the apical surface of chloride cells, and only cells staining positive for Na+/K+-ATPase were CFTR-positive. CFTR-positive cells greatly increased in number (5-fold), area stained (53%) and intensity (29%) after seawater acclimation. In freshwater, CFTR immunoreactivity was light and occurred over a broad apical surface on chloride cells, whereas in seawater there was intense immunoreactivity around the apical pit (which was often punctate in appearance) and a light subapical staining. The results indicate that Na+/K +-ATPase, NKCC and CFTR are all present in chloride cells and support current models that all three are responsible for chloride secretion by chloride cells of teleost fish.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Experimental Biology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1242/jeb.00711","issn":"00220949","usgsCitation":"McCormick, S., Sundell, K., Bjornsson, B.T., Brown, C.L., and Hiroi, J., 2003, Influence of salinity on the localization of Na+/K +-ATPase, Na+/K+/2Cl- cotransporter (NKCC) and CFTR anion channel in chloride cells of the Hawaiian goby (Stenogobius hawaiiensis): Journal of Experimental Biology, v. 206, no. 24, p. 4575-4583, https://doi.org/10.1242/jeb.00711.","startPage":"4575","endPage":"4583","numberOfPages":"9","costCenters":[],"links":[{"id":207708,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1242/jeb.00711"},{"id":232871,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"206","issue":"24","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a3b75e4b0c8380cd62549","contributors":{"authors":[{"text":"McCormick, S.

The near-surface (upper 1.5 cm) sediments are enriched in Cu, with values ranging from 0.4 to 2 wt %. Mineralogical examination revealed that the bulk of the Cu inventory is present as authigenic copper sulfides. Optical microscopy, energy-dispersion spectra, and X-ray data indicate that the main Cu sulfide is covellite (CuS). The formation of authigenic Cu-S phases is supported by the porewater data, which demonstrate that the sediments are serving as a sink for dissolved Cu below sub-bottom depths of 1-2 cm. The zone of Cu removal is consistent with the occurrence of detectable sulfide and the consumption of sulfate. The sediments can be viewed as a passive bioreactor that permanently removes Cu as insoluble copper sulfides. This process is not unlike that which occurs in other forms of bioremediation, such as wetlands and permeable reactive barriers. Above the zone of Cu removal, dissolved Cu maxima in the interfacial porewaters range from 150 to 450 ??g L-1 and reflect the dissolution of a Cu-bearing phase in the surface sediments. The reactive phase is thought to be a component of treatment sludges delivered to the lake as part of cyanide treatment. Flux calculations indicate that the efflux of dissolved Cu from the sediments to the water column (14-51 ??g cm-2 yr-1) can account for the elevated levels of dissolved Cu in lake waters (???50 ??g L-1). Implications for lake recovery are discussed.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Environmental Science and Technology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1021/es034242l","issn":"0013936X","usgsCitation":"Martin, A., Jambor, J., Pedersen, T.F., and Crusius, J., 2003, Post-Depositional Behavior of Cu in a Metal-Mining Polishing Pond (East Lake, Canada): Environmental Science & Technology, v. 37, no. 21, p. 4925-4933, https://doi.org/10.1021/es034242l.","startPage":"4925","endPage":"4933","numberOfPages":"9","costCenters":[],"links":[{"id":232900,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":207726,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1021/es034242l"}],"volume":"37","issue":"21","noUsgsAuthors":false,"publicationDate":"2003-10-07","publicationStatus":"PW","scienceBaseUri":"505a7e50e4b0c8380cd7a472","contributors":{"authors":[{"text":"Martin, A.J.","contributorId":63574,"corporation":false,"usgs":true,"family":"Martin","given":"A.J.","email":"","affiliations":[],"preferred":false,"id":403107,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Jambor, J.L.","contributorId":107460,"corporation":false,"usgs":true,"family":"Jambor","given":"J.L.","email":"","affiliations":[],"preferred":false,"id":403108,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Pedersen, Thomas F.","contributorId":13785,"corporation":false,"usgs":true,"family":"Pedersen","given":"Thomas","email":"","middleInitial":"F.","affiliations":[],"preferred":false,"id":403105,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Crusius, John 0000-0003-2554-0831 jcrusius@usgs.gov","orcid":"https://orcid.org/0000-0003-2554-0831","contributorId":2155,"corporation":false,"usgs":true,"family":"Crusius","given":"John","email":"jcrusius@usgs.gov","affiliations":[{"id":114,"text":"Alaska Science Center","active":true,"usgs":true},{"id":119,"text":"Alaska Science Center Geology Minerals","active":true,"usgs":true}],"preferred":true,"id":403106,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}} ]}
