  9. Utility company installs first Hudson River drilled crossing

    SciTech Connect

    Not Available

    1993-12-01

    Directionally drilling a natural gas pipe line under the Hudson River called for innovative installation techniques including an elevated pullback over a heavily traveled commuter railroad. The 3,700-ft crossing was installed for Central Hudson Gas and Electric Corp. as part of an 11-mi system to supply natural gas from the Iroquois Gas Transmission System to the utility company's Roseton Generating Station. It represents the first horizontal drilled pipe line installation of the Hudson River and the longest drilled crossing in the US Northeast. At the point of installation, the line was designed to contend with an existing glacial till geology, the river crossing, eight electric cables near the right-of-way and the high-speed Metro North Railroad on the east side of the river. Through the interconnection with Iroquois, the utility receives up to 100 MMcfd of natural gas at 750 psig. Total cost of the new system was about $13.1 million with nearly $3.2 million dedicated to the crossing. This paper describes the installation procedures used in this project.

    1983-10-01

    PCB was used in the manufacture of electrical equipment at two General Electric Company (GE) facilities located on the upper Hudson River about 1 km apart in Fort Edward and Hudson Falls (Washington Co.) New York. Discharges of PCB from these plants resulted in concentrations in bottom sediments of the Hudson River which now exceed those of other major rivers by about two orders of magnitude and those of small remote streams by more than three orders of magnitude. Intensive monitoring was initiated in 1977 by the New York State Department of Environmental Conservation (DEC) to ascertain the magnitude of and trends in contaminant conditions of biotic and physical strata. The paper summarizes PCB trends from 1977 to 1981 in three major monitoring components - water, multiplate residues and fish.

    Fitzjaprald, David R.; Garland Lala, G.

    1989-12-01

    Observations of 14 cases of radiation fog in the Hudson River valley in New York State are presented. Our emphasis is to connect the fog prediction problem to mechanisms in the nocturnal boundary layer that influence heat and moisture balances. Surface layer and boundary layer fogs are distinguished by the difference in dominant terms in the saturation specific humidity deficit budget. Fogs that persist longer than approximately 30 minutes are most frequently thicker than 50 m. The ultimate depth to which the fog grows is shown to be determined by initial conditions at sunset and by subsequent evolution of winds in the nocturnal boundary layer, as well as by surface transports and radiative cooling. Estimates of the surface and boundary layer heat budget are presented. Two new phenomena are identified: 1) A jump in specific humidity occurring during the early evening transition that shortens the time required to reach surface layer saturation; and 2) along-valley jetlike winds with maxima near 100 m altitude are shown to be frequent and their occurrence is associated with a threshold value of the along-valley surface pressure gradient. Such jets appear to have an important influence on deep fog, increasing or decreasing its likelihood depending on the sign of heat and moisture advection they associate with.

    The working environment of railways is challenging and complex and often involves high-risk operations. These operations affect both the company staff and inhabitants of the towns and cities alongside the railway lines. To reduce the employees' and public's exposure to risk, railway companies adopt strategies involving trained safety personnel, advanced forms of technology, and special work processes. Nevertheless, unfortunate incidents still occur. To assist railway safety management, researchers developed a visual-analytics system. Using a data analytics workflow, it compiles an incident risk index that processes information about railway incidents. It displays the index on a geographical map, together with socioeconomic information about the associated towns and cities. Feedback on this system suggests that safety engineers and experts can use it to make and communicate decisions. PMID:25073166

  16. Lithospheric architecture beneath Hudson Bay

    2015-07-01

    Hudson Bay overlies some of the thickest Precambrian lithosphere on Earth, whose internal structures contain important clues to the earliest workings of plate formation. The terminal collision, the Trans-Hudson Orogen, brought together the Western Churchill craton to the northwest and the Superior craton to the southeast. These two Archean cratons along with the Paleo-Proterozoic Trans-Hudson internides, form the core of the North American craton. We use S to P converted wave imaging and absolute shear velocity information from a joint inversion of P to S receiver functions, new ambient noise derived phase velocities, and teleseismic phase velocities to investigate this region and determine both the thickness of the lithosphere and the presence of internal discontinuities. The lithosphere under central Hudson Bay approaches ˜350 km thick but is thinner (˜200-250 km) around the periphery of the Bay. Furthermore, the amplitude of the LAB conversion from the S receiver functions is unusually large for a craton, suggesting a large thermal contrast across the LAB, which we interpret as direct evidence of the thermal insulation effect of continents on the asthenosphere. Within the lithosphere, midlithospheric discontinuities, significantly shallower than the base of the lithosphere, are often imaged, suggesting the mechanisms that form these layers are common. Lacking time-history information, we infer that these discontinuities reflect reactivation of formation structures during deformation of the craton.

    After revision of the Railway Business Act in 2000, the abolition of the local railway has increased in Japan. However, continuing activities by people living along local line has been focussed in recent years. Moreover, a lot of local railway's business are obtaining the subsidy from the municipality where railway route is located. When the government puts out the grant to the company, it is necessary to have the accountability for the peoples. This research is focused on the value of the local railways for residents are measured, and an economical value of that is estimate by using the Contingent Valuation Method. As for the route for analysis in Nagano, Bessho-line(Ueda), Yashiro-line(Nagano) and Kamikohchi-line(Matsumoto) were chosen. Moreover, policies of each municipality to these routes are evaluated by using these values.

  5. PCB-pollution problem in the upper Hudson River: From environmental disaster to environmental gridlock

    SciTech Connect

    Sanders, J.E. )

    1989-01-01

    The PCB pollution of the upper Hudson River has been traced to two discharge pipes from capacitor-manufacturing plants of the General Electric Company (GE) at Hudson Falls and Fort Edward, located about 40 miles north of Troy, New York. In August 1974, EPA biologists carried out a field investigation upstream of, at, and downstream of the GE discharge pipes. In September 1975, goaded by articles about PCB-contaminated fish from the Hudson Estuary, the Commissioner of the New York State Department of conservation (NYS DEC) commenced an administrative proceeding against GE, alleging violations of several NY State Environmental Conservation Law sections, and seeking cessation of PCB discharges, penalties for past discharges, and rehabilitation of the upper river. One stipulation of the resulting settlement agreement was that New York State sign off with GE over PCB pollution of the Hudson River and, if the Advisory Committee recommended in favor of rehabilitation, it would use its best efforts to find funds from sources other than GE to help pay for rehabilitation. The future of the PCB problem in the upper Hudson River seems likely to be settled by the outcome of a class-action lawsuit that commercial fisherman have filed against GE. In January 1989, a NEW York Appeals Court voted in favor of the ruling that the fishermen were entitled not only to payments for lost income, but to injunctive relief (which implies that GE must clean up the River). 311 refs., 30 figs., 14 tabs.

  8. Nelson River and Hudson Bay

    NASA Technical Reports Server (NTRS)

    2002-01-01

    Rivers that empty into large bodies of water can have a significant impact on the thawing of nearshore winter ice. This true-color Moderate Resolution Imaging Spectroradiometer (MODIS) image from May 18, 2001, shows the Nelson River emptying spring runoff from the Manitoba province to the south into the southwestern corner of Canada's Hudson Bay. The warmer waters from more southern latitudes hasten melting of ice near the shore, though some still remained, perhaps because in shallow coastal waters, the ice could have been anchored to the bottom. High volumes of sediment in the runoff turned the inflow brown, and the rim of the retreating ice has taken on a dirty appearance even far to the east of the river's entrance into the Bay. The sediment would have further hastened the melting of the ice because its darker color would have absorbed more solar radiation than cleaner, whiter ice.

    NASA Astrophysics Data System (ADS)

    Eaton, D.; Darbyshire, F.

    2009-05-01

    Hudson Bay is a vast inland sea that penetrates deeply into north-central Canada, forming a conspicuous element of the coastline and concealing several fundamental tectonic elements of North America, including most of the Paleoproterozoic Trans Hudson orogen (THO) and the Paleozoic Hudson Bay basin. The THO formed due to a collision between two Archean domains, the Superior and Churchill Provinces of the Canadian Shield, and is similar in scale and tectonic style to the modern Himalayan-Karakorum orogen. Tectonic reconstructions suggest that the lobate shape of the indentor (Superior Province) formed an orogenic template that exerted a persistent influence on the tectonic evolution of the region, resulting in anomalous preservation of juvenile crustal material. Based on analysis of gravity and magnetic data, we propose a model in which juvenile crust in the southeastern part of Hudson Bay formed within an island-arc setting proximal to the Superior Province, in contrast to the Reindeer Zone of Saskatchewan and Manitoba which accreted first to the Churchill Province. Thick, cold and refractory lithosphere that underlies the Bay is well imaged by surface-wave studies and comprises a large component of the cratonic mantle keel that forms the nucleus of the North American continent. The existence of an unusually thick mantle root beneath Hudson Bay indicates that subduction and collision are root-forming (or at least root-preserving) processes. Although the Hudson Bay basin is the largest by surface area of four major intracratonic basins in North America, it is also the shallowest. Available evidence suggests that basin subsidence may have been triggered by eclogitization of crust that was previously thickened during the Trans-Hudson orogeny. Relatively stiff Early Paleozoic lithosphere may have inhibited subsidence of the Hudson Bay basin relative to other basins of similar age in North America.

    In 1859, Robert Kennicott, one of the most promising specimen collectors and young naturalists in the United States, was dispatched to Hudson's Bay Territory by Spencer Fullerton Baird, the Assistant Secretary of the Smithsonian. Kennicott was chosen because of previous experience in Canada, the familiarity with biota of the American Midwest, and because he had a boundless, infectious, enthusiasm for natural history that was typical among Baird's closest protégées. Kennicott was a natural scientific envoy--or missionary--to the officers of the Hudson's Bay Company, and many officers were enthusiastically 'converted' to the cause of collecting and/or overseeing the collection of natural history specimens. Due to this collaboration between Baird, Kennicott and the officers of the Hudson's Bay Company, the Smithsonian became a leading center of Canadian natural history in the Western hemisphere.

    1988-01-01

    Between 1963 and 1980, the Hudson River estuary was the focus of one of the most ambitious environmental research and assessment programs ever performed. The studies supported a series of US federal proceedings involving licenses and discharge permits for two controversial electric power generating facilities: the Cornwall pumped storage facility, and units 2 and 3 of the Indian Point nuclear generating station. Both facilities were to draw large volumes of water from a region of the Hudson used as spawning and nursery habitat by several fish species, including the striped bass. Fishermen and conservationists feared that a major fraction of the striped bass eggs and larvae in the Hudson would be entrained with the pumped water and killed. Additional fish would be killed on trash screens at the intakes. Scientists were asked to aid the utility companies and regulatory agencies in determining the biological importance of entrainment and impingement. This monograph contains both technical papers that present research results and synthesis papers that summarize and interpret the results. The intent was to: (1) summarize the scientific issues and approaches; (2) present the significant results of the Hudson River biological studies; (3) describe the role of the studies in the decision-making process; (4) evaluate the successes and failures of the studies; and (5) present recommendations for future estuarine impact assessments. Separate abstracts are processed for 22 papers for inclusion in the appropriate data bases.

    1993-03-01

    There are several methods for determining sediment accumulation rates in the Hudson River estuary. One involves the analysis of the concentration of certain radionuclides in sediment core sections. Radionuclides occur in the Hudson River as a result of: natural sources, fallout from nuclear weapons testing and low level aqueous releases from the Indian Point Nuclear Power Facility. The following radionuclides have been studied in the authors work: Cesium-137, which is derived from global fallout that started in the 1950's and has peaked in 1963. Beryllium-7, a natural radionuclide with a 53 day half-life and found associated with very recently deposited sediments. Another useful natural radionuclide is Lead-210 derived from the decay of Radon-222 in the atmosphere. Lead-210 has a half-life of 22 years and can be used to date sediments up to about 100 years old. In the Hudson River, Cobalt-60 is a marker for Indian Point Nuclear Reactor discharges. The author's research involved taking sediment core samples from four sites in the Hudson River Estuarine Research Reserve areas. These core samples were sectioned, dried, ground and analyzed for the presence of radionuclides by the method of gamma-ray spectroscopy. The strength of each current pulse is proportional to the energy level of the gamma ray absorbed. Since different radionuclides produce gamma rays of different energies, several radionuclides can be analyzed simultaneously in each of the samples. The data obtained from this research will be compared to earlier work to obtain a complete chronology of sediment deposition in these Reserve areas of the river. Core samples may then by analyzed for the presence of PCB's, heavy metals and other pollutants such as pesticides to construct a pollution history of the river.

  16. A River Summer on the Hudson

    2006-12-01

    River Summer is a month-long faculty development program extending from the continental shelf off New York City to the headwaters of the Hudson in the Adirondack Mountains. During the program, faculty from the Environmental Consortium of Hudson Valley Colleges and Universities teach each other about the Hudson environment, using innovative methods of teaching and learning, with a focus on incorporation of hands-on approaches from the perspective of multiple disciplines. Over four weeks, faculty from research universities, community colleges, liberal arts institutions, and middle and high schools work and live together, on board a research vessel or in a remote tent campsite, for several days at a time. Using the geology, hydrology, and landscape of the River as a foundation, River Summer focuses on understanding development of the Hudson within the context of its natural resources and cultural history. Participants conduct field sampling and analyses and consider issues through approaches that are common to many disciplines: scaling for problem solving; sampling and assessing bias and representation; observing and documenting; representing and depicting; interpretation and assessing relationships and causality; and evaluation. They also get a chance to experience, first-hand, the complexity and often open-ended nature of doing science. By allowing individuals, many of whom come from non-science disciplines, to experience these methods and processes in a safe learning environment, science is made more meaningful and accessible. The program's pedagogy is based on the principles of cognitive psychology and immersive field-, place- and inquiry-based learning. Field programs have been found to provide memorable, transformative experiences for undergraduate students, and our experience with River Summer 2005 and 2006 suggests they are equally effective with faculty. Evaluation shows that River Summer has a significant impact on its participants. Participants develop new

  19. Phosphorus chemistry in the tidal Hudson River

    SciTech Connect

    Fox, L.E. )

    1991-06-01

    A study of inorganic phosphborus in the tidal Hudson River was performed from Noverber 1988 to October 1989. Results indicate that phosphate concentrations are at or near equilibrium with a suspended solid phase consisting of amorphous ferric phosphate in amorphous ferric hydroxide. Equilibrium was observed over most of the river, over most of the year. Undersaturation was observed regularly below river mile 40 in the month of July. It represented the major deviation from equilibration. Low suspended sediment levels and dilution from sea water are believed to be responsible for undersaturation. Dissolved iron was near equilibrium with amorphous ferric hydroxide except in July. Recognition of the wide range of watersheds where phosphorus equilibrium controls phosphate concentrations suggests that the global, terrestrial flux of biologically available phosphorus may be double current estimates.

    The hospital is an integral part of the community, according to James May, CEO and president of Legacy Portland (OR) Hospitals. May has put this principle to work concretely by loaning employees money for initial costs on homes near Emanuel Hospital and Health Center in northeast Portland. Now in its second year, the program has already helped 25 employees purchase homes in a 19-square-mile area targeted for redevelopment. Loans of up to $5,000 for homes with a purchase price of $65,000 or lower are available. The loans can be used for down payments, pre-paid reserves or closing costs. Legacy forgives 20 percent of a loan's outstanding balance each year to employees in good standing. This encourages employees to stay for at least five years. Only the interest payments on the outstanding balance are paid back to Legacy. May spoke recently with Senior Editor Terese Hudson about the program's genesis. PMID:8348171

  2. Lithospheric architecture of the Hudson Bay region (Invited)

    NASA Astrophysics Data System (ADS)

    Eaton, D. W.; Darbyshire, F. A.

    2009-12-01

    Hudson Bay conceals several fundamental tectonic elements of North America, including most of the ca. 1.8 Ga Trans Hudson orogen (THO) and the Paleozoic Hudson Bay basin. Formed due to a collision between the Superior and Churchill Provinces of the Canadian Shield, the THO is similar in scale and tectonic style to the modern Himalayan-Karakorum orogen. During collision, the lobate shape of the indentor (Superior Province) formed an orogenic template that, along with the Sask craton of central North America, exerted a persistent influence on the tectonic evolution of the region resulting in anomalous preservation of juvenile crustal material. Juvenile crust in the southeastern part of Hudson Bay is interpreted to have formed within an island-arc setting proximal to the Superior Province, in contrast to the Reindeer Zone of Saskatchewan and Manitoba, which accreted first to the Churchill Province. Thick, cold and refractory lithosphere that underlies the Bay is well imaged by surface-wave and S-Receiver function studies and comprises a large component of the cratonic mantle keel that forms the nucleus of the North American continent. The existence of an unusually thick mantle root beneath Hudson Bay indicates that subduction and plate collision during the Trans-Hudson orogeny were ‘root-preserving’ (if not ‘root-forming’) processes. Although the Hudson Bay basin is the largest by surface area of four major intracratonic basins in North America, it is also the shallowest. Crustal thinning imaged from ambient-noise tomography is consistent with previous models of basin subsidence caused by extension. Compared to other basins of similar age in North America, however, relatively stiff Early Paleozoic lithosphere may have inhibited subsidence of the Hudson Bay basin.

  3. Roads, railways, and childhood cancers

    Knox, E G

    2006-01-01

    Study objectives To locate geographical sources of engine exhaust emissions in Great Britain and to link them with the birth addresses of children dying from cancer. To estimate the cancer initiating roles of nearby roads and railways and to measure effective ranges. Design Birth and death addresses of all children born between 1955 and 1980 in Great Britain, and dying from leukaemia or other cancer during those years, were linked to locations of railway stations, bus stations, ferry terminals, railways, roads, canals, and rivers. Nearest distances to births and deaths were measured, and migration data relating to children who had moved house were analysed. Excesses of close to hazard birth addresses, compared with close to hazard death addresses, indicate a high prenatal or early postnatal risk of cancer initiation. Setting and subjects Child cancer birth and death addresses and their map references were extracted from an earlier inquiry. Map references of putative hazards were downloaded from the Ordnance Survey national digital map of Great Britain. These data are recorded to a precision of one metre and have ground accuracies around 20 metres. Main results Significant birth excesses were found within short distances of bus stations, railway stations, ferries, railways, and A,B class roads, with a relative risk of 2.1 within 100 m, tapering to neutral after 3.0 km. About 24% of child cancers were attributable to these joint birth proximities. Roads exerted the major effect. Conclusions Child cancer initiations are strongly determined by prenatal or early postnatal exposures to engine exhaust gases, probably through maternal inhalation and accumulation of carcinogens over many months. The main active substance is probably 1,3‐butadiene. PMID:16415262

  4. THE CONSTRUCTION COST ESTIMATE SYSTEM THAT UTILIZES TECHINICAL PROPOSALS IN THE IMPROVEMENT CONSTRUCTION OF THE RAILWAY STRUCTURES

    Seki, Yutaka

    JR East has been made start as a new railway company in line with the reform policy of the Japan national railway in 1987. Along with it, JR have beam required the management emphasizing on the efficiency and quickness as a private enterprise. On the other hand, construction companies have remarkably made progress on the construction technology in recent years. Under the circumstance, we tried to establish the construction cost estimates of the railway improvements utilizing the technical proposals based on high technologies by innovative construction companies. In conclusion, we obtained a construction cost reduction and process speeded by the number of technical proposals and we also had acquired the effect of quality and efficiency in the construction cost estimates.

    This paper summarises the historical development of railway freight vehicles and how vehicle designers have tackled the difficult challenges of producing running gear which can accommodate the very high tare to laden mass of typical freight wagons whilst maintaining stable running at the maximum required speed and good curving performance. The most common current freight bogies are described in detail and recent improvements in techniques used to simulate the dynamic behaviour of railway vehicles are summarised and examples of how these have been used to improve freight vehicle dynamic behaviour are included. A number of recent developments and innovative components and sub systems are outlined and finally two new developments are presented in more detail: the LEILA bogie and the SUSTRAIL bogie.

  6. Reconstruction of the Last Outburst Flood of Glacial Lake Agassiz-Ojibway in Hudson Bay and Hudson Strait

    NASA Astrophysics Data System (ADS)

    Lajeunesse, P.; St-Onge, G.

    2007-12-01

    Hudson Bay and Hudson Strait were the sites of a rapid deglaciation that culminated in the catastrophic drainage of proglacial Lake Agassiz-Ojibway into the North Atlantic at ~8.47 cal kyr BP. It has previously been suggested that this sudden outburst of freshwater may have weakened the thermohaline circulation and triggered the 8200 cal BP cold event recorded in Greenland ice cores. Evidence for the outburst flood included geomorphic features observed on the seafloor of southern Hudson Bay and the identification of a centimeter to decimeter- thick hematite-rich red layer present in Hudson Strait sediment cores. However, unequivocal evidence is still lacking in order to define the way the lake drained (i.e., either by a breach through the ice-dam, a supraglacial spillover or a subglacial flood), whether it drained by one or more pulses and the location of the northward flood routes toward Hudson Bay. In this paper, we present new seafloor images and sediment cores collected onboard the CCGS Amundsen in Hudson Bay and Hudson Strait in 2004 and 2005 that shed light on the dynamics of the final drainage of the ice-dammed lakes. We found that this sudden outburst flood combined with subsequent currents displaced icebergs back-and-forth in a former calving bay to produce preferentially oriented arc-shaped scours on the seafloor. In addition, fields of giant sandwaves were identified in southern Hudson Bay in areas unaffected by arcuate iceberg scours, suggesting that they were protected from iceberg scouring by overlying glacier ice during the lake drainage event. The subglacial origin of the widely distributed sandwaves and the occurrence of many submarine channels lead us to propose that the drainage of Lake Agassiz-Ojibway took place by a buoyant lifting of the rapidly thinning LIS along many subglacial routes that spread over the entire southern Hudson Bay region. We also reveal that the red bed contains two layers deposited by hyperpycnal flows (hyperpycnites

    2010-03-01

    Pakistan is ranked 12th worldwide for passenger kilometres (km) travelled by railway network. The objective of this study was to assess the railway network related morbidity and mortality in Pakistan. Reported deaths and injuries due to this network were extracted from two secondary datasets: (1) an international disaster database and (2) ambulance log registers for the city of Karachi. Over the period from 1997 to 2006, a total of 11 railway disasters resulted in 449 deaths and 840 injuries. An estimated 2.05 passengers died and another 3.84 passengers were injured per billion km travelled in Pakistan, a rate six times higher than Western European countries. The ambulance log showed that one person died every two weeks in Karachi over a period from September 2007 to Jun 2008 (N = 26). The male-to-female ratio of all injury victims (N = 50) was 9:1 with a mean age of 35.6 years. Surveillance of these injuries is essential to implement prevention and control measures in Pakistan.

    Static chamber and gas exchange techniques were used to measure nitrous oxide fluxes from soil and water at five sites within the Hudson Bay Lowland as part of the Northern Wetland Study. Episodic and diffusive mechanisms are indicated as likely sources for nitrous oxide emissions. Episodic emissions could not be detected by the gas exchange technique, therefore, it is not an appropriate measurement method for wetland water emission rate determination. LANDSAT-Thermatic Mapper imagery was used to scale nitrous oxide emissions on a regional scale over the entire Hudson Bay Lowland area.

  12. [Wiplash injury and "railway spine"].

    Thomann, K D; Rauschmann, M

    2004-09-01

    Although post-traumatic stress disorder was only recently admitted into the international classification systems, psychological reactions to traumatic incidents have been frequently described for more than 100 years. The article deals with the mental reactions to a trauma in different historical situations. Included are the "railway spine" injuries of the 19th century, victims of accidents where third party liability could be claimed, accident insurance, the psychological consequences of National Socialism and whiplash injury. The analysis suggests that different reactions don't describe an identical disorder. It seems that reactions to injuries are mainly influenced by the historical and social background and the fact of beeing insured. PMID:15487336

  13. Analysis of railway track vibration

    Ono, K.; Yamada, M.

    1989-04-01

    Analytical formulae are developed for estimating the amplitudes of the vibrations generated in railway tracks by wheels and rail discontinuities or by unevennesses on their surfaces. Rails are assumed to be supported elastically on concrete sleepers by resilient rail-pads inserted between them. The elasticities and the masses of track materials and those of the roadbed are also taken into consideration. It is shown that after an impulse is applied to the track, not only is a vibration with a comparatively low natural frequency generated, but also traveling waves with higher frequencies, and the latter propagate lengthwise along the track or downwards into the roadbed. With the assumption that the power spectral density of the unevennesses on the rail surface is in proportion to the third power of the wavelength, or to (wavenumber) -3, the amplitudes of the vibrations in railway tracks supported by rail-pads and roadbeds with various magnitudes of elastic constants are analyzed and the values for each one-third octave band are estimated. The velocity of the vibration takes on a maximum value for the band with a center frequency of 63 Hz, which corresponds to the resonant frequency of the system composed of the wheel and the track. As the frequency increases beyond this value, the velocity of the vibration takes on a second maximum value at a frequency of about 1000 Hz. These estimates are compared with the data obtained from field measurements and reasonably good correlations are found between them.

  14. Sound radiation from railway sleepers

    NASA Astrophysics Data System (ADS)

    Zhang, Xianying; Thompson, David J.; Squicciarini, Giacomo

    2016-05-01

    The sleepers supporting the rails of a railway track are an important source of noise at low frequencies. The sound radiation from the sleepers has been calculated using a three-dimensional boundary element model including the effect of both reflective and partially absorptive ground. When the sleeper flexibility and support stiffness are taken into account, it is found that the radiation ratio of the sleeper can be approximated by that of a rigid half-sleeper. When multiple sleepers are excited through the rail, their sound radiation is increased. This effect has been calculated for cases where the sleeper is embedded in a rigid or partially absorptive ground. It is shown that it is sufficient to consider only three sleepers in determining their radiation ratio when installed in track. At low frequencies the vibration of the track is localised to the three sleepers nearest the excitation point whereas at higher frequencies the distance between the sleepers is large enough for them to be treated independently. Consequently the sound radiation increases by up to 5 dB below 100 Hz compared with the result for a single sleeper whereas above 300 Hz the result can be approximated by that for a single sleeper. Measurements on a 1/5 scale model railway track are used to verify the numerical predictions with good agreement being found for all configurations.

  18. Observations of fresh, anticyclonic eddies in the Hudson Strait outflow

    NASA Astrophysics Data System (ADS)

    Sutherland, David A.; Straneo, Fiammetta; Lentz, Steven J.; Saint-Laurent, Pierre

    2011-12-01

    The waters that flow out through Hudson Strait, a coastal system that connects Hudson Bay with the Labrador Sea, constitute the third largest freshwater contribution to the northern North Atlantic. Recent studies have documented the mean structure and transport of the outflow, as well as highlighting significant variability on synoptic scales (days-week). This study examines the outflow's variability on these synoptic scales through the use of observations collected by a mooring array from 2005 to 2006. We focus on the mechanisms that cause the freshwater export to be concentrated in a series of discrete pulses during the fall/winter season. We find that the pulses occur once every 4.4 days on average and are associated with anticyclonic, surface-trapped eddies propagated through the strait by the mean outflow. Their occurrence is related to the passage of storms across Hudson Bay, although local instability processes also play a role in their formation. The eddies are responsible for approximately 40% of the mean volume transport and 50% of the mean freshwater transport out of the strait. We discuss the implications of this freshwater release mechanism on the delivery of nutrient-rich and highly stratified waters to the Labrador shelf, a productive region south of Hudson Strait.

  20. Reproductive success of belted kingfishers on the upper Hudson River.

    PubMed

    Bridge, Eli S; Kelly, Jeffrey F

    2013-08-01

    Belted kingfishers (Megaceryle alcyon) are predators in many North American aquatic ecosystems; as such, they are prone to bioaccumulation of certain environmental contaminants. In 2002 and 2004, kingfisher eggs collected near the upper Hudson River in New York had elevated concentrations of polychlorinated biphenyls (PCBs), and the kingfisher population in this area was reported to be at risk because of PCB exposure. From 2007 to 2009, the authors monitored 69 kingfisher nests on the Hudson River to track both nest success and survival of individual nestlings. The study site consisted of 2 adjacent sections of the Hudson River, 1 upstream and 1 downstream of a historic PCB source. The authors compared models of nest success that differentially incorporated the following 4 variables that they deemed most likely to affect reproductive output: 1) river section (upstream vs downstream of PCB source), 2) year, 3) hatch date, and 4) abandonment by 1 parent. After ranking models according to Akaike's information criterion for small sample sizes, it was clear that parental abandonment was the most important of the factors examined. River section was not an important parameter, and overall nesting success was slightly higher in the PCB-contaminated section than in the upstream area. These findings support the conclusion that kingfisher productivity is not adversely impacted by PCB contamination in the upper Hudson River. PMID:23633435

    We present a general method for modeling safety aspects of railway control systems. Using our modeling method, one can progressively refine an abstract railway safety model, sucessively adding layers of detail about how a real system actually operates, while maintaining a safety property that refines the original abstract safety property. This method supports a top-down approach to specification of railway control systems and to proof of a variety of safety-related properties. We demonstrate our method by proving safety of the classical block control system.

  9. Geological Setting and Petroleum Potential of the Paleozoic Hudson Platform, Northern Canada

    The Hudson Platform covers an area of 600,000 km2 and represents one of the largest Paleozoic sedimentary basins in Canada. The Hudson Platform contains the large Hudson Bay Basin and smaller Moose River Basin. The Hudson Bay and Moose River basins are surrounded and underlain by Precambrian igneous and metamorphic rocks of the Canadian Shield. The Hudson Platform contains Ordovician to Cretaceous sedimentary strata, with a maximum known thickness of about 2500 m in Hudson Bay. The lower Paleozoic succession includes Late Ordovician to Early Devonian shallow marine carbonates and thin mudstones, deposited during widespread early Paleozoic marine inundation of the Canadian Shield, and Early to Late Devonian marine carbonates, evaporates, and mudstones deposited in saucer-shaped, isolated basin depocentres. There is no record of late Paleozoic sedimentation in the region, perhaps related to cratonic uplift accompanying the Alleghenian Orogeny. Lower Paleozoic strata are unconformably overlain by thin, erosional remnants of Middle Jurassic and Early Cretaceous nonmarine sandstones, mudstones and lignite seams (Moose River Basin) and Early Cretaceous marine sandstones and mudstones (Hudson Bay Basin). The Hudson Platform is currently considered a frontier prospect for hydrocarbon exploration. However, the long- held view that the region is underlain by a thin sedimentary succession with no appreciable hydrocarbon source rocks or reservoir intervals is erroneous. Geological and geophysical data indicate the Hudson Bay Basin contains many prospective petroleum reservoir and trap types, potentially including hydrothermal dolomite. Recent studies indicate Upper Ordovician oil shales are widespread and may have generated hydrocarbons in deeper parts of the Hudson Bay Basin. New high resolution bathymetric surveys in northern Hudson Bay have led to the recognition of circular sea-floor depressions similar to fluid or gas-escape pockmarks. A modern re-evaluation of the

    1995-10-01

    Chlorofluorocarbon (CFC) concentrations in the Hudson estuary were found to be greater than the atmospheric solubility equilibrium concentration, demonstrating that the entire reach is contaminated with CFCs from local wastewater discharge. Samples have been collected along the axis of the lower Hudson estuary over a 5-month period to assess temporal and spatial variability of their wastewater sources. The highest CFC concentrations were found in water collected near Manhattan. In this region, CFC-11 (CCl{sub 3}F) and CFC-12 (CCl{sub 2}F{sub 2}) were 3 to 5 and 10 to 20 times saturation, respectively. There appears to be a continuous CFC source in the New York City area, although the magnitude of this source declined during summer months. Other large CFC source were found near Albany, and in Haverstraw Bay (60 km north of Manhattan). 29 refs., 6 figs., 3 tabs.

  11. Impact of impingement on the Hudson River white perch population

    SciTech Connect

    Barnthouse, L W; Van Winkle, W

    1980-01-01

    The impact of power plant impingement on the 1974 and 1975 year classes of the Hudson River white perch population is assessed using a simple model derived from Ricker's theory of fisheries dynamics. The impact of impingement is expressed in the model as the conditional mortality rate, rather than as the more commonly used exploitation rate. Since the calculated impact is sensitive to errors in the estimation of population size and total mortality, ranges of probable values of these quantities are used to compute upper and lower bounds on the fractional reduction in abundance of each year class. Best estimates of abundance and mortality are used to compute the conditional impingement mortality rate separately for each plant and month. The results are used to assess the relative impacts of white perch impingement at six Hudson River power plants and to identify the seasons during which the impact is highest.

  12. Polychlorinated biphenyl transport in the Hudson River, New York

    Turk, John T.; Troutman, David E.

    1981-01-01

    Polychlorinated biphenyls (PCB's) have been entering the Hudson River estuary since 1951. Concentration and loading of PCB 's in the river below Waterford, N.Y., are controlled at present by resuspension of sediments containing these substances; therefore , until the amount of PCB 's in the sediments is significantly lowered, reduction of point-source PCB discharge from the present rate of 0.4 kilograms per day will produce no more than a 10% reduction in loading to the river. Potential concentrations of PCB 's in solution and suspension in the river can be predicted by a simple model for mixing and dilution. From a known range of PCB influent rates, total PCB loading to the Hudson River from above Waterford is shown to be between 2,000 and 12,000 kilograms per year. (USGS)

    1994-01-20

    This article describes the monitoring of methane emissions at 39 wetland ecosystem sites in the Hudson Bay Lowland. The study sites were located along a transect from the James Bay Coast at the tip of the Hudson Bay to Kinosheo Lake near Moosonee, Ontario, Canada. Measurements of methane flux were made using a static chamber technique. Weak statistical relationships were noted at each site between the daily methane flux rate, ground-water depth, and peat temperatures. On a regional scale, a significant correlation was noted over the complete range of sites between the seasonal methane flux and the average position of the ground-water table. Other observations are also described. 51 refs., 7 figs., 4 tabs.

  14. Hudson River PCB clean-up to begin

    NASA Astrophysics Data System (ADS)

    Showstack, Randy

    U.S. Environmental Protection Agency Administrator Christie Whitman signed the Record of Decision on 1 February to clean up a stretch of the Hudson River that has been contaminated by polychlorinated biphenyls (PCBs). The decision calls for dredging 2 million cubic meters of PCB-contaminated sediment from a 64-kilometer stretch of the upper Hudson to remove about 68,000 kilograms of PCBs.The plan follows years of scientific study about whether the PCBs were safely encased in the sediment or posed a continuing hazard, and concern over whether the PCBs can be safely removed without stirring up a larger pollution problem along the river. The EPA found that PCBs in the sediment are not safely buried because erosion and river flows can redistribute river sediment. The agency also found that although PCBs break down naturally over time, this degradation does not render them harmless.

  15. Hudson's theorem for finite-dimensional quantum systems

    NASA Astrophysics Data System (ADS)

    Gross, D.

    2006-12-01

    We show that, on a Hilbert space of odd dimension, the only pure states to possess a non-negative Wigner function are stabilizer states. The Clifford group is identified as the set of unitary operations which preserve positivity. The result can be seen as a discrete version of Hudson's theorem. Hudson established that for continuous variable systems, the Wigner function of a pure state has no negative values if and only if the state is Gaussian. Turning to mixed states, it might be surmised that only convex combinations of stabilizer states give rise to non-negative Wigner distributions. We refute this conjecture by means of a counterexample. Further, we give an axiomatic characterization which completely fixes the definition of the Wigner function and compare two approaches to stabilizer states for Hilbert spaces of prime-power dimensions. In the course of the discussion, we derive explicit formulas for the number of stabilizer codes defined on such systems.

  4. Determining the Sediment Budget of the Lower Hudson River

    NASA Astrophysics Data System (ADS)

    Prugue, R.; Nitsche, F. O.; Kenna, T. C.

    2010-12-01

    Sediment is a major component of the Hudson River Estuary, constantly being resuspended and deposited. The Lower Hudson River is heavily dredged due to its use as a shipping lane for large vessels traversing through the harbor. A detailed sediment budget is key for management of the estuary including development, optimizing dredging, restoration, and mitigating future sea-level changes. However, it has been difficult to produce a detailed sediment budget due to the large amounts of data required to obtain a reputable value and account for spatial variability. Thus, previous budget estimates were based on approximations of input and output of material The Hudson River Benthic Mapping Project, which was funded by the New York State Department of Environmental Conservation, resulted in a comprehensive data set that includes a dense network of subbottom profiles and over 400 sediment cores from the Hudson River Estuary. Using industrial seismic interpretation software and X-ray fluorescence spectrometry, we identified the thickness and distribution of 20th century sediment deposition by mapping the sediment layer with elevated levels of anthropogenic lead, which is a characteristic for sediment deposition since 1920/1930. This 20th century sediment are of special concern because of the high amounts of contaminants that were being introduced into the estuary during this time. By combining analysis of different sections of the estuary, we are able to quantify the amount of 20th century deposition between Poughkeepsie and the New York Harbor and demonstrate that a detailed sediment budget can be obtained. This analysis reveals that ~35,000,000 cubic meters of sediment has been deposited in the study area during the last 70-80 years, which corresponds to an annual deposition of 450,000 - 500,000 cubic meters. Following this analysis, we aim to obtain a sediment mass and compare our results with other estimates that were taken in the past.

  5. Impact Ejecta above an Unconformity in Hudson River Sediments

    NASA Astrophysics Data System (ADS)

    Abbott, D. H.; Gogan, N.; Breger, D.

    2012-12-01

    We examined three Hudson River cores just above a step increase in density that we infer to be an erosional unconformity circa 2300 BP in age (Goodbred et al., 2006). Each core has a layer containing impact ejecta and marine microfossils that lies directly above the unconformity. As the river water is too fresh for marine organisms, there are no marine microfossils in the sediments above and below this unusual layer. The marine microfossils are pelagic and benthic foraminifera, radiolarians, and coccoliths. The impact ejecta include marine microfossils coated with Sn oxide, often in crystalline form. The Sn oxide coating contains quantitative levels of Ni as determined by microprobe analysis. Ni is a marker for extraterrestrial material. Sn oxide also appears as a coating on glauconite grains within the layer. Glauconite is highly unstable and only forms in a marine setting. Marine sediments on the continental shelf outside the mouth of the Hudson River contain abundant glauconite. We also found impact breccia containing flow-textured glass, shocked ilmenite, pyroxene, and K-feldspar. Some of the glass cemented impact breccias are enriched in pyrite. The layer above the unconformity increases in thickness towards the mouth of the Hudson. The water depth of the cores in some cases exceeds 10 meters. Because the flow depths of storm surges do not exceed 10 meters and are generally less than 3 meters, we can eliminate storm surge as a cause of the event. Alternatively, tsunamis can exhibit flow depths that exceed 10 meters, suggesting that the erosional event was produced by an impact-generated tsunami. The cores containing the unconformity are located between 27 and 41 km upstream from the mouth of the Hudson River.

  6. Trends in chlorinated hydrocarbon levels in Hudson River basin sediments.

    1998-01-01

    Analysis of sections from dated sediment cores were used to establish geographic distributions and temporal trends of chlorinated hydrocarbon contaminant levels in sediments from natural waters of the Hudson River basin. Radiometric dating was based primarily on the depth distribution of 137(Cs) in the cores and on the occurrence of detectable levels of 7(Be) in surface sediment samples. Eighteen sampling sites included several along the main stem of the Hudson, its major tributaries, and components of the New York/New Jersey (NY/NJ) harbor complex. Drinking-water reservoirs were sampled to place upper limits on atmospheric inputs. Core sections were analyzed for polychlorinated biphenyls (PCBs), 1,1,1-trichloro-2,2-bis(p-chlorophenyl) ethane (DDT)-derived compounds, chlordane, and dioxins. Sediment concentrations of most contaminants at most sites have decreased significantly since the mid-1960s. The data provide a basinwide perspective on major point-source inputs of PCBs to the upper Hudson River and of 2,3,7,8-tetrachlorodibenzo-p-dioxin and DDT to the lower Passaic River. Evidence was found for significant but poorly characterized sources of PCBs and chlordane to the western NY/NJ harbor, and of highly chlorinated dioxins to the upstream sites on the main stem of the Hudson. The results indicate that analysis of dated sediment samples is a most effective and efficient monitoring tool for the study of large-scale geographic and temporal trends in levels of particle-associated contaminants.

  14. Precambrian Processes, the Trans-Hudson Orogen, and Cratonic Keels: Insights From Teleseismic Tomography in Northern Hudson Bay, Canada

    NASA Astrophysics Data System (ADS)

    Liddell, M. V.; Bastow, I. D.; Gilligan, A.; Kendall, J. M.; Darbyshire, F. A.

    2015-12-01

    Earth conditions in the Precambrian, and their effect upon the formation of cratons and orogenies from that era, are not fully understood. For example, the precise onset of modern plate tectonics remains ambiguous; it has been hypothesised to have begun anywhere from ~4.1Ga (Hopkins, 2008) to ~1Ga (Stern, 2005). Also, the exceptional depth to which fast wave-speed and geoid anomalies extend beneath some cratons points to the existence of thick "cratonic keels", the origin of which remains unexplained. To improve our understanding of the early Earth processes, geological evidence preserved within ancient plates that have remained largely unchanged since the Precambrian can be used. The rocks of northern Hudson Bay include Archean domains, the Paleoproterozoic Trans-Hudson Orogen (THO), and lie atop one of the largest cratonic keels on Earth (Bastow et al., 2013), making this region an ideal laboratory for study of Precambrian processes. Here, we use seismological data recorded at Canadian POLARIS and Hudson Bay Lithospheric Experiment (HuBLE) stations to perform a relative arrival-time study of northern Hudson Bay region and the THO. Waveforms are aligned using the adaptive stacking routine of Rawlinson et al. (2004), and inversions are produced using the Fast Marching Tomography (FMTOMO) inversion code of Rawlinson et al. (2006). Our inversions provide an improved velocity model of the lithosphere and upper mantle of northern Canada, suggesting updated boundaries between lithospheric blocks at mantle depths and constituting new body-wave constraints on their structure. The results are used to address a number of outstanding questions regarding the processes that formed the THO and the Laurentian Keel of North America.

  15. Acoustic Optimization of Railway Sleepers

    NASA Astrophysics Data System (ADS)

    NIELSEN, J. C. O.

    2000-03-01

    A mathematical model of vertical wheelset/track interaction is developed and adopted for minimization of sound power generated by railway sleepers (mono-bloc or bi-bloc). The influence of sleeper material properties, sleeper shape and properties of ballast and rail pads on sleeper sound power can be investigated. The wheelset/track interaction is simulated in the frequency domain by using a so-called moving irregularity model with a given displacement amplitude spectrum. Boundary element models of the acoustic medium (air) are developed for mono-bloc and bi-bloc sleepers. Radiation efficiencies are calculated and compared for the different sleeper designs. From the results obtained in a parametric study, it is concluded that the sound power generated by the sleepers is strongly influenced by ballast stiffness and damping and by rail pad stiffness. Further, it is concluded that a bi-bloc sleeper with appropriate dimensions of the connecting bar can lead to a 2-3 dB(A) reduction of sound power compared to a reference mono-bloc sleeper.

  7. Structure of the Crust and Uppermost Mantle Beneath Hudson Bay Based on Ambient- Noise Tomography

    NASA Astrophysics Data System (ADS)

    Pawlak, A.; Eaton, D. W.

    2008-12-01

    Hudson Bay is a vast inland sea that penetrates deeply into north-central Canada, forming a conspicuous element of the North American coastline. The Bay conceals several fundamental tectonic elements of North America, including most of the Paleoproterozoic Trans Hudson orogen, the Paleozoic Hudson Bay basin and a large part of the lithospheric root beneath the Precambrian core of North America. This study is focused on regional crustal structure based on ambient-noise tomography. Twenty-one months of continuous ambient- noise recordings have been acquired from 31 broadband seismograph stations that encircle Hudson Bay. These stations are part of the Hudson Bay Lithospheric Experiment (HuBLE), an international project that is currently operating more than 40 broadband seismograph stations around the periphery of Hudson Bay. Following established processing procedures that include trace normalization and spectral whitening, cross- correlations are computed for all possible station pairs. The resulting waveforms are treated as Green functions, from which group velocity dispersion measurements can be made. Since Hudson Bay freezes during winter months, there is a pronounced asymmetry to the Green functions indicative of noise sources along the Atlantic seaboard. Preliminary results indicate shield-like conditions in most areas, but reduced crustal velocities beneath the Hudson Bay basin.

  10. Cytochrome P450IA mRNA expression in feral Hudson River tomcod

    SciTech Connect

    Kreamer, G.L.; Squibb, K.; Gioeli, D.; Garte, S.J.; Wirgin, I. )

    1991-06-01

    The authors sought to determine if levels of cytochrome P450IA gene expression are environmentally induced in feral populations of Hudson River tomcod, a cancer prone fish, and whether laboratory exposure of tomcod to artificially spiked and naturally contaminated Hudson sediments can elicit a significant response. Using Northern blot analysis, they found levels of P450IA mRNA in tomcod collected from two Hudson River sites higher than those in tomcod from a river in Maine. Depuration of environmentally induced Hudson tomcod P450IA mRNA was rapid, with an initial detectable decline in P450 gene expression by 8 hr and basal levels reached by 5 days. Intraperitoneal injection of {beta}-napthoflavone in depurated Hudson tomcod resulted in a 15-fold induction of P450 gene expression within 26 hr. Exposure of depurated Hudson tomcod to natural sediment spiked with two PAHs resulted in a 7-fold induction of P450 gene expression. Exposure of depurated tomcod to sediment from a contaminated Hudson site also resulted in a 7- to 15-fold induction of P450IA mRNA expression. Northern blot analysis revealed a second polymorphic cytochrome P450IA mRNA band in some tomcod which was also detected by Southern blot analysis. Induction of cytochrome P450IA mRNA in Atlantic tomcod may provide a sensitive biomarker of environmentally relevant concentrations of some pollutants in the Hudson and other northeastern tidal rivers.

  18. New Fluid Prevents Railway Ice

    NASA Technical Reports Server (NTRS)

    2001-01-01

    Through a licensing agreement between NASA's Ames Research Center and Midwest Industrial Supply, Inc. (MIS), two MIS products have been enhanced with NASA's anti-icing fluid technology. MIS offers the new fluid in two commercial products, the Zero Gravity(TM) Third Rail Anti-Icer/Deicer and the Ice Free Switch(R). Using NASA's fluid technology, these products form a protective-coating barrier that prevents the buildup of ice and snow. Applying the fluid to the railway components prior to ice or snowstorm works as an anti-icing fluid, remaining in place to melt precipitation as it hits the surface. It also functions as a deicing fluid. If applied to an already frozen switch or rail, it will quickly melt the ice, free the frozen parts, and then remain in place to prevent refreezing. Additional benefits include the ability to cling to vertical rail surfaces and resist the effects of rain and wind. With the Ice Free Switch, it takes only five minutes to treat the switch by spraying, brushing, or pouring on the product. Ice Free Switch requires as little as one gallon per switch whereas other deicing fluids require five to ten gallons of liquid to effectively melt ice. Zero Gravity serves the same anti-icing/deicing purposes but applies fluid to the third rail through a system that is easily installed onto mass transit cars. A tank of fluid and a dispensing system are placed underneath the train car and the fluid is applied as the train runs its route.

  19. Body burdens of mercury in lower Hudson River area anglers.

    PubMed

    Gobeille, Alayne K; Morland, Kimberly B; Bopp, Richard F; Godbold, James H; Landrigan, Philip J

    2006-06-01

    The Hudson River has been a federally designated Superfund site for over 20 years. Discharges of industrial waste and of treated and untreated sewage and atmospheric deposition have introduced mercury and other persistent pollutants to the Hudson River ecosystem. Despite New York and New Jersey health advisories, many local anglers and their family members continue to consume fish caught from the river. To evaluate associations between body burden of mercury and local fish consumption, we conducted a cross-sectional study of 191 anglers recruited from piers and fishing clubs. Participants were administered a questionnaire to obtain information on local fish consumption, and 65% (124 individuals) provided a blood sample used to determine mercury levels. Mercury levels ranged from below the limit of detection (0.75 ng/mL) to 24.0 ng/mL. Participants who reported eating locally caught fish had significantly higher levels of mercury (mean (M)=2.4 ng/mL, standard error (SE)=1.2) than anglers who never ate locally caught fish (M=1.3 ng/mL, SE=1.1). A positive dose-response pattern was also observed, where participants who reported eating locally caught fish more than once a week had higher mercury levels (M=2.6 ng/mL, SE=1.1) than anglers eating fish less frequently (M=2.0 ng/mL, SE=1.2) or never at all (M=1.3 ng/mL, SE=1.1). These findings indicate that consumption of fish caught from the lower Hudson River area is a route of human exposure to mercury for the angling community. PMID:16226244

  20. Exchange of nitrous oxide within the Hudson Bay lowland

    NASA Technical Reports Server (NTRS)

    Schiller, C. L.; Hastie, D. R.

    1994-01-01

    The source strength of atmospheric trace gases from natural ecosystems must be quantified in order to assess the effect of such inputs on the background tropospheric chemistry. A static chamber technique and a gas exchange technique were used to determine the emissions of nitrous oxide from five sites within the Hudson Bay Lowland, as part of the Northern Wetland Study. Two mechanisms, one diffusive and the other episodic, were found likely to be responsible for the emissions of nitrous oxide. The annual diffusive flux ranged from -3.8 mg(N2O)/sq m in a treed bog to 7.9 mg(N2O)/sq m in an open fen. The addition of the episodic flux, increased this range to -2.1 mg(N2O)/sq m and 18.5 mg(N2O)/sq m respectively. These episodic emissions occurred in from 2.5% to 16.7% of the samples during the late summer peak emission period. Since the gas exchange rate could not detect the episodic emissions, it was found to be a poor method for water emission rate determination within the wetland. LANDSAT-Thermatic Mapper (TM) imagery was used to scale the emissions, from the chamber level to an integrated average over the entire Hudson Bay Lowland. The total emission rate of N2O from the Hudson Bay Lowland, was determined to be 1.2 Gg(N2O)/year, of which 80% was attributed to episodic emissions.

    Chromite ore processing residue occurs at over 130 sites in Hudson County, New Jersey. Many of these sites are in urban residential areas. This waste is a result of 70 years of chromate and bichromate chemical manufacturing. At least 15% of the sites contain total chromium concentrations greater than 10,000 mg/kg, with hexavalent content ranging from about 1 to 50%. Continuing leaching of this waste results in yellow-colored surface water runoff and yellow deposits on the soil surface and inside basement walls. The chemistry, environmental fate, health effects, and human exposure potentials for this waste are described. Images FIGURE 1. PMID:1935843

    On August 8, 2009, a private airplane collided with a sightseeing helicopter over the Hudson River near Hoboken, New Jersey. All three people aboard the airplane, the pilot and two passengers, and all six people aboard the helicopter, the pilot and five passengers, were killed. The National Transportation Safety Board report on the accident identified inherent limitations of the see-and-avoid concept, inadequate regulations, and errors by the pilots and an air traffic controller as causing or contributing to the accident. This paper presents the results of analyzing the accident using the Systems-Theoretic Accident Model and Processes (STAMP) approach to determining accident causation.

  5. Modeling Guidelines for Code Generation in the Railway Signaling Context

    NASA Technical Reports Server (NTRS)

    Ferrari, Alessio; Bacherini, Stefano; Fantechi, Alessandro; Zingoni, Niccolo

    2009-01-01

    Modeling guidelines constitute one of the fundamental cornerstones for Model Based Development. Their relevance is essential when dealing with code generation in the safety-critical domain. This article presents the experience of a railway signaling systems manufacturer on this issue. Introduction of Model-Based Development (MBD) and code generation in the industrial safety-critical sector created a crucial paradigm shift in the development process of dependable systems. While traditional software development focuses on the code, with MBD practices the focus shifts to model abstractions. The change has fundamental implications for safety-critical systems, which still need to guarantee a high degree of confidence also at code level. Usage of the Simulink/Stateflow platform for modeling, which is a de facto standard in control software development, does not ensure by itself production of high-quality dependable code. This issue has been addressed by companies through the definition of modeling rules imposing restrictions on the usage of design tools components, in order to enable production of qualified code. The MAAB Control Algorithm Modeling Guidelines (MathWorks Automotive Advisory Board)[3] is a well established set of publicly available rules for modeling with Simulink/Stateflow. This set of recommendations has been developed by a group of OEMs and suppliers of the automotive sector with the objective of enforcing and easing the usage of the MathWorks tools within the automotive industry. The guidelines have been published in 2001 and afterwords revisited in 2007 in order to integrate some additional rules developed by the Japanese division of MAAB [5]. The scope of the current edition of the guidelines ranges from model maintainability and readability to code generation issues. The rules are conceived as a reference baseline and therefore they need to be tailored to comply with the characteristics of each industrial context. Customization of these

  7. Reactions to railway noise in Denmark

    NASA Astrophysics Data System (ADS)

    Andersen, T. V.; Kühl, K.; Relster, E.

    1983-03-01

    People's reactions to railway noise were studied along seven Danish railway lines with traffic intensities from 30 to about 300 trains per 24 hours. The calculated sound levels varied between 43 and 71 dB(A) for LAeq,24h and between 78 and 102 sB(A) for LAmax . 615 persons were interviewed. One third of these felt strongly or somewhat annoyed by the railway noise. The relations between the noise level and the extent of annoyance or various kinds of behaviour (telephone conversation, TV-listening, opening of windows, sleep, etc.) were found. The relations were found for both LAeq,24h and LAmax , but the correlation for LAmax is generally bad. Noise in the evenings was found to be more annoying than noise in other daytime periods. More than half of the interviewees answered that goods trains especially were a problem. People exposed to noise at their place of work seem to feel more annoyed by railway noise than other people.

    This study reviews the development of railway safety in Finland from 1959 to 2008. The results show that the level of safety has greatly improved over the past five decades. The total number of railway fatalities did not show any obvious decreasing or increasing trend during the first decade, but since the early 1970s the annual number of fatalities has decreased from about 100 to 20. The estimated overall annual reduction per year from 1970 to 2008 was 5.4% (with a 95% confidence interval from -8.2% to -2.6%). The reduction in subcategories per million train-kilometres from 1959 to 2008 was 4.4% per year for passengers, 8.3% for employees, 5.0% for road users at level crossings and 3.6% for others (mainly trespassers). The safety improvement for passengers and staff was probably influenced by the introduction of central locking of doors in passenger cars and improved procedures to protect railway employees working on the tracks. The number of road users killed at level crossings has fallen due to the installation of barriers and the construction of overpasses and underpasses at crossings with dense traffic, removal of level crossings, and an improvement of conditions such as visibility at crossings. The number of trespasser fatalities has seen the least decline. Key plans for the future include further reduction of the number of level crossings on the state railway network from the current roughly 3500-2200 by 2025, and involving communities in safety work related to railway trespassers.

  9. Anomalous topography on the continental shelf around Hudson Canyon

    1979-01-01

    Recent seismic-reflection data show that the topography on the Continental Shelf around Hudson Canyon is composed of a series of depressions having variable spacings (< 100 m to 2 km), depths (1-10 m), outlines, and bottom configurations that give the sea floor an anomalous "jagged" appearance in profile. The acoustic and sedimentary characteristics, the proximity to relict shores, and the areal distribution indicate that this rough topography is an erosional surface formed on Upper Pleistocene silty sands about 13,000 to 15,000 years ago by processes related to Hudson Canyon. The pronounced southward extension of the surface, in particular, may reflect a former increase in the longshore-current erosion capacity caused by the loss of sediments over the canyon. Modern erosion or nondeposition of sediments has prevented the ubiquitous sand sheet on the Middle Atlantic shelf from covering the surface. The "anomalous" topography may, in fact, be characteristic of areas near other submarine canyons that interrupt or have interrupted the longshore drift of sediments. ?? 1979.

  10. Gravity anomalies and deep structure of eastern Hudson bay

    The Cape Smith and Belcher foldbelts of Lower Proterozoic (Aphebian) rocks form parts of the proposed Circum-Superior suture which separates the Superior and Churchill structural provinces of the Canadian Shield. Recent marine gravity surveys in eastern Hudson Bay (1976-1979) show that the distinctive linear gravity pattern of paired positive and negative anomalies along the Cape Smith foldbelt of northern Ungava extends southwards into Hudson Bay to the Belcher Islands. Interpretation of five gravity profiles across the Cape Smith and Belcher foldbelts suggests that the Churchill crust is thicker and denser than the Superior. The boundary between the two contrasting crustal blocks is interpreted as a collisional suture. The rocks of the foldbelts which are progressively more volcanic northwards are the source of a residual positive anomaly associated with the Cape Smith foldbelt and a series of discontinuous positive residual anomalies in the Bay. To the north the thicknesses of the foldbelt rocks are estimated to be between 4 and 9 km with a local maximum of 13 km in the northernmost profile. To the south in the Belcher Islands, where geological estimates of formation thickness and measured rock densities provide more constraints on the interpretation of the residual anomalies, the foldbelt rocks are generally 6-7 km thick with a local maximum thickness of about 9 km. One possible interpretation of paleomagnetic results for Belcher Islands rocks in terms of a two-plate model lends support to the collision hypothesis.

  11. Sources of polycyclic aromatic hydrocarbons to the Hudson River Airshed

    Sources of polycyclic aromatic hydrocarbons (PAHs) to the Hudson River Estuary Airshed were investigated using positive matrix factorization (PMF). A three-city dataset was used to obtain common factor profiles. The contributions of each factor on each sampling day and site were then determined, and a sensitivity analysis was conducted. A stable eight-factor solution was identified. PMF was able to identify a factor associated with air-surface exchange. This factor contains low-molecular weight PAHs and was a dominant contributor to the measured PAHs concentrations. Factors linked to motor vehicle use (diesel and gasoline vehicle emissions and evaporative/uncombusted petroleum) and natural gas combustion were also major contributors. Motor vehicle combustion and oil combustion factors were the predominant contributors to particle-phase PAHs, while natural gas combustion, air-surface exchange, and evaporative/uncombusted petroleum factors made substantial contributions to gas-phase PAH concentrations. In contrast to fine particulate matter (PM2.5), which is dominated by regional transport, spatial variations in PAH concentrations suggest that PAH concentrations in the Hudson River Estuary Airshed are dominated by sources within the New York-New Jersey urban-industrial complex.

    A one-dimensional dynamic-flow model and a one-dimensional solute-transport model were used to evaluate the effects of hypothetical public-supply water withdrawals on saltwater intrusion in a 133-mile reach of the tidal Hudson River between Green Island dam, near Troy, N.Y., and Hastings-on-Hudson, N.Y. Regression techniques were used in analyses of current and extreme historical conditions, and numerical models were used to investigate the effect of various water withdrawals. Of four withdrawal scenarios investigated, simulations of a 27-day period during which discharges at Green Island dam averaged 7,090 ft3/s indicate that increasing the present Chelsea pumping-station withdrawal rate of 100 Mgal/d (million gallons per day) to 300 Mgal/d would have the least effect on upstream saltwater movement. A 90-day simulation, during which discharges at Green Island dam averaged 25,200 ft3/s, indicates that withdrawals of 1,940 Mgal/d at Chelsea would not measurably increase chloride concentrations at Chelsea under normal tidal and meteorological conditions, but withdrawals of twice that rate (3,880 Mgal/d) could increase the chloride concentration at Chelsea to 250 mg/L.

    Piermont Marsh, located approximately 40 kilometers north of the mouth of the Hudson River, provides an opportunity to evaluate local and regional vegetation shifts primarily due to changes in land use over the past 600 years. A high-resolution palynological record from Piermont Marsh, NY shows consistent presence of "weedy" genera (Ambrosia, Plantago, and Rumex) beginning around 1760. This increase in herbaceous genera is also marked by a decline in arboreal taxa, attributed to land clearance by settlers. Typha (cattail) also experiences a very large increase coincident with the rise in weedy genera, accounting for as much as 70% of pollen grains counted in a sample. Although the profile for Gramineae (grass) appears consistent throughout the core, grain size separations show periods dominated by the native marsh Spartina species downcore and the invasive Phragmites in recent decades. A pre-settlement interval shows a period of decreased pollen deposition and increased charcoal, which could be due to sea level change, drought, or Native American use. Comparison with other marsh records in the Hudson River estuary shows general agreement in chronology with interesting differences in sedimentation rate, which can be attributed to sea level change, natural disturbance, or anthropogenic influences of development.

    The Southern Hudson Bay (SH) population of polar bears (Ursus maritimus) resides in a seasonal sea ice environment and is the most southerly population in the species’ range. Therefore, SH polar bears may be among the first to show negative effects associated with climate warming and consequent loss of sea ice. Polar bears in the neighboring Western Hudson Bay (WH) population have declined significantly in body condition since the mid-1980s, and a recent study indicated that the size of the WH population declined by about 22% between 1987 and 2004. Similarly, SH bears have shown a significant decline in body condition since the mid-1980s, and an assessment of the current status of the SH population was therefore needed. We applied open population capture-recapture models to data collected from 1984-86 and 1999- 2005 to estimate population size and survival. The size of the SH population appears to be unchanged from the mid-1980s (1984-1986: 641, 95% CI = 401, 881) vs. 2003-2005: 681 (95% CI = 401, 961). Point estimates of survival for subadults and adult females were 94% (95% CI = 68%, 100%) in 1984-1985 to 89% (95% CI = 79%, 99%) in 2003-2005, but imprecision exhibited by overlap of the confidence intervals prevented us from unequivocally concluding that this 5% decline in survival was not a chance occurrence. Similarly, a decline of 7% in survival was estimated for subadult and adult males over the same time period (male survival estimates = 88% (95% CI = 77%, 100%) in 1984-1985; 81% (95% CI = 66%, 96%), but again we could not unequivocally conclude that this decline was not chance. There was weak evidence of lower survival of cubs, yearlings, and senescent adults in the recent time period. This, combined with the evidence of significant declines in body condition for all age and sex classes, which were greatest for pregnant females and subadults, suggests this population may be under increased stress at this time. However, we did not find any clear

    In 2004, railway suicide accounted for 5.3% of all suicides in Belgium. In 2008, Infrabel (Manager of the Belgian Railway Infrastructure) introduced a railway suicide prevention programme, including identification of suicide hotspots, i.e., areas of the railway network with an elevated incidence of suicide. The study presents an analysis of 43 suicide hotspots based on Infrabel data collected during field visits and semi-structured interviews conducted in mental health facilities in the vicinity of the hotspots. Three major characteristics of the hotspots were accessibility, anonymity, and vicinity of a mental health institution. The interviews identified several risk and protective factors for railway suicide, including the training of staff, introduction of a suicide prevention policy, and the role of the media. In conclusion, a comprehensive railway suicide prevention programme should continuously safeguard and monitor hotspots, and should be embedded in a comprehensive suicide prevention programme in the community.

    In modern railway automatic train protection and automatic train control systems, odometry is a safety relevant on-board subsystem which estimates the instantaneous speed and the travelled distance of the train; a high reliability of the odometry estimate is fundamental, since an error on the train position may lead to a potentially dangerous overestimation of the distance available for braking. To improve the odometry estimate accuracy, data fusion of different inputs coming from a redundant sensor layout may be used. The aim of this work has been developing an innovative localisation algorithm for railway vehicles able to enhance the performances, in terms of speed and position estimation accuracy, of the classical odometry algorithms, such as the Italian Sistema Controllo Marcia Treno (SCMT). The proposed strategy consists of a sensor fusion between the information coming from a tachometer and an Inertial Measurements Unit (IMU). The sensor outputs have been simulated through a 3D multibody model of a railway vehicle. The work has provided the development of a custom IMU, designed by ECM S.p.a, in order to meet their industrial and business requirements. The industrial requirements have to be compliant with the European Train Control System (ETCS) standards: the European Rail Traffic Management System (ERTMS), a project developed by the European Union to improve the interoperability among different countries, in particular as regards the train control and command systems, fixes some standard values for the odometric (ODO) performance, in terms of speed and travelled distance estimation. The reliability of the ODO estimation has to be taken into account basing on the allowed speed profiles. The results of the currently used ODO algorithms can be improved, especially in case of degraded adhesion conditions; it has been verified in the simulation environment that the results of the proposed localisation algorithm are always compliant with the ERTMS requirements

    Induction or eddy current thermography is used to detect surface cracks in ferritic steel. The technique is applied to detect surface cracks in rails from a moving test car. Cracks were detected at a train speed between 2 and 15 km/h. An automated demonstrator system for testing railway wheels after production is described. While the wheel is rotated, a robot guides the detection unit consisting of inductor and infrared camera over the surface.

  3. Rotational equations usable for railway wheelsets

    2014-03-01

    The Euler equation is a correct way for writing rotational moments of solids. But it is simple only if written in rotating frames. Applying it to railway wheelsets is difficult because it necessitates using the Euler angles, or Euler parameters, combined to rotation matrices or, numerically more stable, quaternions. Euler angles can be avoided in railway specific codes, by writing dynamical equations in track frames. However, academic literature [Landau LD, Lifshitz EM. Mechanics (Institute of Physical Problems, USSR Academy of Sciences, Moscow), Vol. 1, Course of theoretical physics. 21st English ed. Oxford (UK): Elsevier; 1960; Shabana AA, Zaazaa KE, Sugiyama H. Railroad vehicle dynamics. CRC Press; 2008.] does not provide simple solutions as to how properly writing equations of gyroscopic moments in no rotating frames. This paper describes how it is possible, owing to an approximation validated for railway applications, to avoid Euler angles and rotation matrices, while correctly taking into account gyroscopic effects. Using a most severe example, emphasising gyroscopic effects, it is demonstrated that a fast specific code using the approximation provides results equivalent to those of an multi body system generalised code with no approximation.

    Isotopic and structural data from the juvenile Reindeer zone of the Trans-Hudson orogen, northern Saskatchewan, indicate a pre-1.85 Ga thermotectonic event, possibly reflecting arc-continent collision, followed by a more extensive, nappe-forming, ca. 1.83-1.80 Ga thermotectonism during terminal continent-continent collision. Preliminary data from the adjacent, ensialic Cree Lake zone suggest high-grade reworking of Archean crust by the pre-1.85 Ga event. In the Rae province to the west, high-grade metamorphism and reworking of Archean crust occurred about 2.0 Ga and may be related to the formation of the coeval Taltson magmatic zone.

    The distribution of metals (Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb, and Zn) in bottom and suspended sediments from the ocean up the Hudson River estuary for 70 km were analyzed. The bottom sediments has a metal concentration maximum in the harbor. Everywhere studied, the metal concentrations in suspension are much higher than in the bottom sediments by 30 times for Cd, 20 times for Cu, and 10 to 15 times for Co, Cr, Ni, Pb, and Zn. The composition of metals in the suspended material varied along the estuary with a large metal maximum in the harbor and again in Haverstraw Bay. By standardizing toxic metal concentrations to Fe, a maximum level of pollution in New York Harbor is indicated, along with a lesser maximum in Haverstraw Bay.

    Rivers and estuaries around the world are the focus of human settlements and activities. Needs for clean water, ecosystem preservation, commercial navigation, industrial development, and recreational access compete for the use of estuaries, and management of these resources requires a detailed understanding of estuarine morphology and sediment dynamics. This article presents an overview of the first estuary-wide study of a heavily used estuary, the Hudson River, based on high-resolution acoustic mapping of the river bottom. The integration of three high-resolution acoustic methods with extensive sampling reveals an unexpected complexity of bottom features and allows detailed classification of the benthic environment in terms of riverbed morphology, sediment type, and sedimentary processes.

    The Hudson River (Federal Project No. 41) was one of seven waterways that the U.S. Army Corps of Engineers-New York District (USACE-NYD) requested the Battelle Marine Sciences Laboratory (MSL) to sample and evaluate for dredging and disposal in March 1994. Sediment samples were collected from the Hudson River. Tests and analyses were conducted on Hudson River sediment core samples. The evaluation of proposed dredged material from the Hudson River included bulk sediment chemical analyses, chemical analyses of site water and elutriate, water-column and benthic acute toxicity tests, and bioaccumulation studies. Individual sediment core samples collected from Hudson River were analyzed for grain size, moisture content, and total organic carbon (TOC). A composite sediment sample, representing the entire area proposed for dredging, was analyzed for bulk density, specific gravity, metals, chlorinated pesticides, polychlorinated biphenyl (PCB) congeners, polynuclear aromatic hydrocarbons (PAH), and 1,4-dichlorobenzene. Site water and elutriate water, prepared from the suspended-particulate phase (SPP) of Hudson River sediment, were analyzed for metals, pesticides, and PCBS. Water-column or SPP toxicity tests were performed with three species. Benthic acute toxicity tests were performed. Bioaccumulation tests were also conducted.

  12. Salt Marsh Formation in the Lower Hudson River Estuary

    NASA Technical Reports Server (NTRS)

    2001-01-01

    Salt marshes are constant depositional environments and as a result contain accurate indicators of past relative sea level rise and salinity. The Hudson River marshes are at least twice as deep when compared to coastal marshes on either side of the mouth of the Hudson. The reason for this difference in sedimentation is unclear. This study uses macrofossil data as well as sediment stratigraphy in order to understand the formation and evolution of these marshes. The composition of seeds, roots, shoots and foraminifera, are used to indicate past sea levels. The four sites involved in this study are, from south to north, the Arthur Kill Marsh in Staten Island (40 36 N, 74 77W), Piermont marsh (N 4100; 73 55W) Croton Point (41 14 N; 73 50W) and Iona Island (41 18N, 73 58W). These are all tidally influenced but with increasing distances from the New York Bight, which gives a good spectrum of tidal influence. AMS-C14 dates on basal macrofossils will document the time of each marsh formation. Basal material from Arthur Kill (8 m) includes freshwater seeds such as Viola, Potomageton and Alnus along with Salix buds. Basal material from Croton Point (10 m) includes fibrous woody material, foraminifera and Zanichellia seeds and other brackish vegetational components. The basal material from Piermont (13.77 m) is lacking any identifiable macrofossils between 150 and 500 microns. The basal material from Iona Island (10 m) has vegetation such as Scirpus and Cyperus seeds, probably implying a brackish environment. The freshwater origin of the Arthur Kill marsh in Staten Island is significant because it predates either sea level rise or the western channel incision. Additional implications for this study include evidence for changes in river channel geomorphology. Reasons for the relatively deeper river marshes include possible basal clay compaction, high production due to river and marine nutrients as well as tectonic activity. This study provides the groundwork for more high

  13. Sea-Level Rise Impacts on Hudson River Marshes

    The response of tidal marshes to increasing sea-level rise is uncertain. Tidal marshes can adapt to rising sea levels through vertical accretion and inland migration. Yet tidal marshes are vulnerable to submergence if the rate of sea-level rise exceeds the rate of accretion and if inland migration is limited by natural features or development. We studied how Piermont and Iona Island Marsh, two tidal marshes on the Hudson River, New York, would be affected by sea-level rise of 0.5m, 1m, and 1.5m by 2100. This study was based on the 2011-2012 Coastal New York LiDAR survey. Using GIS we mapped sea-level rise projections accounting for accretion rates and calculated the submerged area of the marsh. Based on the Hudson River National Estuarine Research Reserve Vegetation 2005 dataset, we studied how elevation zones based on vegetation distributions would change. To evaluate the potential for inland migration, we assessed land cover around each marsh using the National Land Cover Database 2011 Land Cover dataset and examined the slope beyond the marsh boundaries. With an accretion rate of 0.29cm/year and 0.5m of sea-level rise by 2100, Piermont Marsh would be mostly unchanged. With 1.5m of sea-level rise, 86% of Piermont Marsh would be flooded. For Iona Island Marsh with an accretion rate of 0.78cm/year, sea-level rise of 0.5m by 2100 would result in a 4% expansion while 1.5m sea-level rise would cause inundation of 17% of the marsh. The results indicate that Piermont and Iona Island Marsh may be able to survive rates of sea-level rise such as 0.5m by 2100 through vertical accretion. At rates of sea-level rise like 1.5m by 2100, vertical accretion cannot match sea-level rise, submerging parts of the marshes. High elevations and steep slopes limit Piermont and Iona Island Marsh's ability to migrate inland. Understanding the impacts of sea-level rise on Piermont and Iona Island Marsh allows for long-term planning and could motivate marsh conservation programs.

    One objective of the May 2004 pilot study for the Lagrangian Transport and Transformation Experiment (LaTTE) was to determine the relative advantages of studying the Hudson River plume within the spatial and temporal context provided by a research-friendly coastal ocean observatory. Towards this end, a shelf-wide observational backbone was locally enhanced with high-resolution relocatable systems in the New York Bight apex. The permanent backbone includes local acquisition of international satellite ocean color imagery, a network of long-range High Frequency radars, and a cross-shelf Endurance line occupied by an autonomous underwater glider. The higher resolution HF Radar, glider and mooring network was originally deployed in the vicinity of the Long-term Ecosystem Observatory, where it attracted a large number of scientists to coastal upwelling experiments conducted offshore Tuckerton, NJ from 1998-2001. With scientific interest in the series of coastal upwelling experiments having peaked and run its course through the publication phase, the high resolution systems were moved to the New York Bight Apex to hopefully repeat the cycle of attracting a variety of scientists to a specific interdisciplinary process study site. During the LaTTE pilot study, datasets from the nested observation network were assembled in real-time at a shore-based acquisition center, and high-resolution atmospheric forecasts were performed. Specific emphasis was placed on communicating the real time observatory data and forecasts to scientists on a pair of research vessels conducting a dye release with the associated physical, biological and chemical sampling. Observational results from the observatory will be reviewed, with specific emphasis placed on the observed response of the Hudson River plume to a windshift from upwelling to downwelling favorable winds in the middle of the pilot experiment. This includes a shift from a relatively weak plume flowing eastward along the south shore of

    The Hudson Bay system (HBS) is a shallow inland sea in the Arctic, composed of Hudson Strait, Foxe Basin/Channel, James Bay, and Hudson Bay. Dissolved inorganic carbon (DIC) and total alkalinity (TA) measurements were used to investigate the state of ocean acidification, specifically calcium carbonate saturation states (Ω) and pH. The freshwater sources were identified from the relationship between oxygen isotope composition (δ18O) and salinity to understand the role of freshwater in ocean acidification. The saturation state of seawater with respect to calcium carbonate (Ω) in surface water (<10 m) of the HBS was strongly influenced by river runoff. Aragonite under-saturation (Ωarg < 1) was observed in the surface water of the south-eastern Hudson Bay, where the river runoff fraction was high (>10%). The watershed characteristics, however, influenced the alkalinity of river runoff in different parts of Hudson Bay, which contributed to Ω variation in the coastal region. In southwestern Hudson Bay where the watershed is dominated by limestone, Ω was higher compared to eastern Hudson Bay, where the watershed consists of an igneous rock formation. In deeper waters, low Ω is caused by remineralization of organic matter. The highest DIC concentrations (>2300 µmol/kg) were observed in the depths of central Hudson Bay with a pHtotal of 7.49 and Ωarg of 0.37. Over 67% and 22% of the bottom water of Hudson Bay was undersaturated with respect to aragonite and calcite respectively, despite Hudson Bay being very shallow (less than 250 m deep). The aragonite saturation horizon in the central Hudson Bay was around 50 m.

  16. Kalman Filter Based Railway Tracking from Mobile LIDAR Data

    2015-08-01

    This study introduces a new method to reconstruct 3D model of railway tracks from a railway corridor scene captured by mobile LiDAR data. The proposed approach starts to approximate the orientation of railway track trajectory from LiDAR point clouds and extract a strip, which direction is orthogonal to the trajectory of railway track. Within the strip, a track region and its track points are detected based on the Bayesian decision process. Once the main track region is localized, rail head points are segmented based on the region growing approach from the detected track points and then initial track models are reconstructed using a third-degree polynomial function. Based on the initial modelling result, a potential track region with varying lengths is dynamically predicted and the model parameters are updated in the Kalman Filter framework. The key aspect is that the proposed approach is able to enhance the efficiency of the railway tracking process by reducing the complexity for detecting track points and reconstructing track models based on the use of the track model previously reconstructed. An evaluation of the proposed method is performed over an urban railway corridor area containing multiple railway track pairs.

    Bottom sediment samples were collected from six location along a section of the Hudson River Estuary, 5.3 to 82.7 km from the ocean. These samples were analyzed for particle and, due to the bimodal distribution of the sediment, were seperated into two size fractions, fine (<7.8 um) and coarse (7.8-62 um). These fractions were subject to a sequential chemical phase extraction procedure to differenciate the ion exchangeable, carbonate, metallic oxide coating, and organic phases. The extracted phases were analyzed with an inductively coupled plasma atomic emission spectrophotometer for Cd, Co, Cc, Cu, Fe, Ni, Pb, and Zn. Metals were found to be associated largely with fine particle-size fraction. The concentration of fine particles (especially the <2 um size mode within the fine fraction) is a crucial in influencing overall metal content. This is evidenced by strong correlations between the <2 {mu}m or clay mode and concentrations in the metallic-oxide coating phase. Various metal/metal relationships exist among the phases and fractions studied and are highlighted by strong correlations, such as Ni and Zn, and Cu and Cd. The trends associated among the metal and mud concentrations are significant in terms of assessing the bioavailability of heavy metals within the river and estuary system, and as a result, provide valuable insight into the ultimate fate of pollutants which are introduced to this unique environment. 24 refs., 5 figs., 2 tabs.

    In support of more than a decade of litigation, scientists devoted unprecedented effort to modeling the impact of electric power generation on the Hudson River striped bass population. When the Cornwall pumped storage facility was first proposed, opponents of the project argued that enormous numbers of striped bass eggs and larvae would be entrained with the pumped water and killed. Several years later, when the US Atomic Energy Commission held hearings to investigate the potential environmental impacts of Indian Point Unit 2, a nuclear power plant nearing completion 25 km downriver from Cornwall, it was argued that young striped bass would be entrained through the condensers with the cooling water and killed by thermal and mechanical stress. In addition, fish would be killed by impingement on the trash screens. The AEC staff recommended that a cooling tower be built at Indian Point to reduce cooling-water requirements and, therefore, entrainment and impingement mortality. The most sophisticated models failed to provide useful long-term impact predictions. However, simpler models, used to evaluate alternatives for mitigation, were instrumental in arranging a negotiated settlement.

    During summer months, dissolved oxygen (DO) concentrations in the lower Hudson estuary were usually lower than atmospheric equilibrium values. Distributions of DO along the axis of the estuary can be described by three general characteristics. Firstly, surface and bottom values lie on a single trend when plotted against salinity. Secondly, maximum DO concentrations were observed 50--75 km upstream of Manhattan at salinities off 5--15 ppt. Thirdly, the lowest DO concentrations were observed near Manhattan, New York, at salinities of 15--25 ppt and vary systematically with freshwater discharge rate. Minimum DO concentrations during times of similar freshwater discharge were substantially lower for water samples collected between 1978 and 1984 than for those collected between 1989 and 1993. These two periods were also distinguished by occurrences of intense phytoplankton blooms that produced supersaturated DO concentrations at salinities of 5--15 ppt for the period of 1989 to 1993. The increase in the minimum DO concentration in the water near Manhattan is probably in response to improved wastewater treatment at Passaic Valley, NJ; North River, NY; and other wastewater-treatment facilities.

    The occurrence, distribution, and temporal patterns of pesticide concentrations were studied in the Hudson River Basin during 1994 - 96. This article presents the results of three separate pesticide studies conducted as part of the U.S. Geological Survey (USGS) National Water Quality Assessment (NAWQA) program. Pesticides were found in all three studies, but rarely at concentrations exceeding any U.S. Environmental Protection Agency drinking-water standards. The highest concentrations were detected during and immediately after the first runoff following pesticide applications in the late spring and early summer. The herbicides atrazine and metolachlor were the most commonly detected pesticides and were present in nearly every sample collected from streams draining agricultural areas; they also were detected in many streams draining areas with other land uses. Herbicides were most often detected, and had the highest concentrations, in samples from streams draining agricultural areas, whereas insecticides such as diazinon were most commonly detected, and had the highest concentrations, in samples from streams draining urban areas.

  1. Polychlorinated biphenyl release from resuspended Hudson River sediment.

    2007-02-15

    Three shear turbulence resuspension mesocosms (STORM tanks) were used to examine the release of polychlorinated biphenyls (PCBs) from resuspended Hudson River sediment. Twenty-two percent of the resuspended PCBs desorbed after 2 h, and 35% +/- 8% of PCBs were in the dissolved phase after apparent steady state was reached in 2 days. After the first resuspension event, the solids were allowed to settle and the quiescent time was varied to determine whether the labile pool of PCBs is recharged during sediment consolidation. The steady-state log Koc values for the third subsequent resuspension were higher than for the first event due to lower dissolved PCB concentrations; the particulate PCB concentrations were constant between events. With 1 day of consolidation between resuspension events, the dissolved concentration of all congeners decreased an average of 8% +/- 5% between subsequent resuspension events. With 4 days between events, only the dissolved pentachlorinated PCBs decreased significantly (p = 0.002), suggesting that the easily desorbable PCBs recharge when there is sufficient time between resuspension events.

    The investigation of pollen, spores, charcoal, organic carbon content, C/N ratios, and radiometric dating provides a paleoecological study of Tivoli North Bay (42oN, 74oW), lower Hudson River. This freshwater tidal marsh record reveals vegetational changes which reflect local and regional vegetational and climatic shifts. Significant charcoal maxima at the base of the core appear to be parallel to the well-dated 500-yr charcoal maxima in Piermont Marsh downriver, implying a regional climatic impact of the Medieval Warming Interval in the lower Hudson Valley. European settlement is marked by very abrupt shift in vegetation and sediment composition as a result of deforestation, invasive species introduction, and infrastructure construction. Betula became a successful replacement of forest dominants such as Quercus, Pinus, and Tsuga. Weedy species including Ambrosia, Impatiens, Chenopodiaceae and Gramineae expand as human impact increases. Higher sedimentation rate due to higher inorganic input appears to contribute to marsh composition changes as woody taxa such as Salix, Cephalanthus, Fraxinus, and Vitis appear in the wetland in the most recent centuries. Additional radiometric control linking stratigraphy from Tivoli North Bay to other Hudson River wetlands as well as pollen and spore analysis of river and air traps will lead to a better understanding of the Hudson watershed history. Significant extended droughts in the Hudson watershed due to natural variability have major implications for future water availability in this landscape.

    A number of railway operation noise sources other than those leading to the far field (largely wheel/rail), train pass-by noise, are identified and briefly discussed. People primarily affected by these may include railway staff and passengers on the train, railway trackside staff, and wayside residents. Both environmental pollution and hearing protection may be involved. Sources considered include the following: close proximity wheel/rail noise; locomotive noise; freight vehicle noise; warning signal noise; near field bridge noise; marshalling yard noise; flange squeal on tight curves; maintenance machine noise; and track machinery warning horn noise.

    1978-01-01

    Ground water in the Hudson River basin occurs in unconsolidated deposits and consolidated rock. Sand and gravel units of the unconsolidated deposits, which occur principally in valley bottoms, form the best aquifers and commonly provide well yields of several hundred gallons per minute. Carbonate aquifers are the most productive consolidated rock units. Ground water in the Hudson River basin is generally hard and may contain appreciable amounts of iron, salts in solution, or sulfur locally. Basic data on the availability of ground water in the Hudson River drainage area are compiled in (1) a hydrogeologic map of the drainage basin; (2) a table of well depths, yields, concentrations of selected chemical constituents, and hardness of ground water, listed by county and aquifer type; (3) a short text describing the occurrence of ground water in the basin; and (4) a bibliography of ground-water reports pertinent to the area studied.

    2011-08-01

    Estuaries may be subject to warming due to global climate change but few studies have considered the drivers or seasonality of warming empirically. We analyzed temperature trends and rates of temperature change over time for the Hudson River estuary using long-term data, mainly from daily measures taken at the Poughkeepsie Water Treatment Facility. This temperature record is among the longest in the world for a river or estuary. The Hudson River has warmed 0.945 °C since 1946. Many of the warmest years in the record occurred in the last 16 years. A seasonal analysis of trends indicated significant warming for the months of April through August. The warming of the Hudson is primarily related to increasing air temperature. Increasing freshwater discharge into the estuary has not mitigated the warming trend. PMID:21720614

    The study presents state-of-the-art in analytical and numerical modelling of random vertical irregularities of continuously welded ballasted railway tracks. The common model of railway track irregularity vertical profiles is applied, in the form of a stationary and ergodic Gaussian process in space. Random samples of track irregularity vertical profiles are generated with the Monte-Carlo method. Based on the numerical method developed in the study, the minimum and recommended sampling number required in the random analysis of railway bridges and number of frequency increments (harmonic components) in track irregularity vertical profiles simulation are determined. The lower and upper limits of wavelengths are determined based on the literature studies. The approach yields track irregularity random samples close to reality. The track irregularity model developed in the study can be used in the dynamic analysis of railway bridge / track structure / highspeed train systems.

    In 2012, the global ocean tides atlas FES has been updated with the financial support of the French Space Agency (CNES). The examination of the tidal energy budget from the hydrodynamic solution has demonstrated the critical impact of the tidal dissipation in Hudson Bay (over-estimated in FES2012) for the accuracy of global solution especially in the Atlantic. To further explore this issue, a regional study of the tidal hydrodynamics of the Hudson Bay has been carried out with a numerical model (the finite elements model T-UGOm) and observations (altimetry-derrived and in situ data). This study aims to answer questions about the role of tidal dissipation in the Hudson system in relation with the global ocean tides. Among the numerical parameters, the two most critical in terms of tidal dissipation are the bathymetry and the friction coefficient. A sensitivity study has been carried out using the standard bathymetry data set (GEBCO, ETOPO, Smith and Sandwell) and prescribing regionally varying friction coefficients. In addition, a new Hudson bay bathymetry has been reconstructed from ship tracks sounding and other direct depth measurements. Despite these improvements, mostly due to the reconstructed bathymetry, the total energy dissipated by the bottom friction in the Hudson Bay is still significantly too large. The reason for that could be the large remaining uncertainties in the bathymetry especially in Fox Basin. Another reason could be the limitation of 2D modelling in accurately reproducing the energy dissipation in a resonant system such as the Hudson Bay, especially the effect of vertical momentum diffusion in the water column. Consequently, a 3D configuration has been set up to extend our sensitivity study. The results of this work will be presented, concentrating particularly on the energy budget.

    The upper Hudson River has been heavily contaminated with polychlorinated biphenyls (PCBs) due to discharges from former electrical capacitor plants in Hudson Falls and Fort Edward, NY. An epidemiologic study was conducted to assess the impact of dietary and residential exposure on PCB body burden among older, long-term, non-occupationally exposed adults living in the vicinity of these former capacitor plants. The study population consisted of 133 persons 55-74 years of age who had lived in Hudson Falls or Fort Edward for 25 years or more. The comparison group consisted of 120 persons from Glens Falls, which is upriver. Both groups were interviewed, and blood samples were obtained for congener-specific PCB analysis. Persons from the study area reported greater past consumption of Hudson River fish than did the comparison area, but current rates were very low in both areas. The geometric mean serum PCB concentrations for the study and comparison populations did not differ significantly (3.07 ppb wet weight and 3.23 ppb, respectively, for total PCB). Serum PCB concentrations increased with cumulative lifetime exposure to PCBs from Hudson River fish consumption (p<0.10). Persons who lived within 800 m of the river did not have significantly greater serum PCB concentrations than the control population, nor did persons who lived downwind and within 800 m of a PCB-contaminated site. The results indicate no detectable differences in serum PCB levels according to proximity or wind direction relative to local point sources, but lifetime consumption of Hudson River fish was positively associated with serum PCB concentrations.

    Tropical Cyclones (TCs) lead to potentially severe coastal flooding through wind surge and also through rainfall-runoff processes. There is growing interest in modeling these processes simultaneously. Here, a statistical approach that can facilitate this process is presented with an application to the Hudson River Basin that is associated with the New York City metropolitan area. Three submodels are used in sequence. The first submodel is a stochastic model of the complete life cycle of North Atlantic (NA) tropical cyclones developed by Hall and Yonekura (2011). It uses archived data of TCs throughout the North Atlantic to estimate landfall rates at high geographic resolution as a function of the ENSO state and of sea surface temperature (SST). The second submodel translates the attributes of a tropical cyclone simulated by the first model to rainfall intensity at selected stations within the watershed of Hudson River. Two different approaches are used and compared: artificial neural network (ANN) and k-nearest neighbor (KNN). Finally, the third submodel transforms, once again, by using an ANN approach and KNN, the rainfall intensities, calculated for the ensemble of the stations, to the streamflows at specific points of the tributaries of the Hudson River. These streamflows are to be used as inputs in a hydrodynamic model that includes storm surge surge dynamics for the simulation of coastal flooding along the Hudson River. Calibration and validation of the model is carried out by using, selected tropical cyclone data since 1950, and hourly station rainfall and streamflow recorded for such extreme events. Four stream gauges (Troy dam, Mohawk River at Cohoes, Mohawk River diversion at Crescent Dam, Hudson River above lock one nr Waterford), a gauge from a tributary in the lower Hudson River, and over 20 rain gauges are used. The performance of the proposed model as tool for storm events is then analyzed and discussed.

    The Hudson River Estuary (HRE) is adjacent to large metropolitan areas including New York City. Understanding the variable energy conditions for transporting sediments is key to deal with environmental pollution such as the controversial burial and dredging of PCB's in the HRE. We studied sediment transport in the HRE by examining more than 150 cores and grab samples interpreted within the framework of acoustic images. The HRE sedimentary environments were defined based on quantitative estimates of grain size, sedimentary structures, bioturbation, and sedimentation rates and were divided into: channel, channel banks, subtidal flats, tributaries, and islands. Diatom assemblages were used to determine the extent of salt-water intrusion and sediment reworking in the estuary. Along a longitudinal profile, the estuary can be subdivided into: (1) sandy inner fluvial (furthest upstream), (2) muddy central portions, and (3) sandy outer marine. We classified sedimentary facies for the central and fluvial parts of the system (1 and 2). The HRE basin is nearly filled with sediment and tidal energy is focused within the channel and its banks. In the central basin where the estuary is wide (up to 4 km), flood currents are more energetic along the eastern channel bank and the ebb currents lead to minor sediment deposition on the western bank, but only where the system is out of equilibrium with its sediment load. The energy of the tides is accentuated along narrow segments of the estuary that are locally constrained by gorges of the Hudson Valley Highlands leading to erosion and the trapping of sediments. Beyond the banks of the channel, the subtidal flats that were filled with sediment by 0.5 to 3ka, are tranquil environments where the sediment is homogenized by bioturbation and reworked by waves as the estuary shallowed. Occasional high-energy events, (possibly flood-related) eroded the subtidal flats sediment as shown by rare rip-up clasts found in the cores. The inner

    The Hudson River Estuary has large inputs of phosphorus and other nutrients from sewage discharge. Concentrations of soluble reactive phosphorus (SRP) reach at least 4 uM during the summer low-flow period. Biological utilization of phosphorus and other nutrients is usually minimal because of the high turbidity and short residence time of the water. Therefore SRP is normally a conservative tracer of salinity, with maximum concentrations found off Manhattan and decreasing to the north. Despite this abundance of SRP, some components of the dissolved organic phosphorus (DOP) appear to be rapidly cycled by microbes. The objective of this study was to measure this DIP cycling during both the high- and low-flow periods. We measured the concentrations of SRP and DOP, the SRP turnover rate, algal and bacterial biomass, and the substrate turnover rates of two microbial cell-surface phosphatases, alkaline phosphatase (AP) and 5[prime] - nucleotidase (5PN). SRP concentrations ranged from about 0.5-4 uM, DOP was usually less than 1 uM. SRP and AP turnover were slow (generally < 5%/h), but 5PN substrate turnover was high with a median rate of 100%/h. Furthermore, over 30% of the phosphate hydrolyzed by 5PN was immediately taken up. If the nucleotide-P concentration is conservatively assumed to be 5 nM, than the rate of phosphate utilization from DOP is nearly equal to that from SRP. That is paradoxical considering the large SRP concentration, but suggests that much of this SRP may be biologically unavailable due to complexation with iron or other processes.

    Non-invasive methods of assessing animal health and life history are becoming increasingly popular in wildlife research; hair samples from polar bears (Ursus maritimus), are being used to study an ever broader range of anthropogenic and endocrine compounds. A number of contaminants are known to disrupt endocrine function in polar bears. However, the relationship between mercury and cortisol remains unknown, although mercury is an endocrine disruptor in other species. Here, we examine the relationship between concentrations of cortisol and total mercury (THg) analyzed in guard hair from 378 polar bears (184 females, 194 males) sampled in Western Hudson Bay, 2004-2012. The difference in mean cortisol concentration between female (0.8 ± 0.6 pg/mg) and male (0.7 ± 0.5 pg/mg) polar bears bordered on significance (p = 0.054). However, mean mercury concentration was significantly greater (p = 0.009) in females (4.7 ± 1.4 μg/g) than males (4.3 ± 1.2 μg/g). Hair cortisol in males was significantly influenced by mercury, age, and fatness, as well as interactions between mercury and year, mercury and fatness, and year and fatness (all: p < 0.03) (multiple regression analysis, whole model: r(2) = 0.14, F(7,185) = 4.43, p = 0.0001). Fatness was the only significant variable in the multiple regression analysis for females (r(2) = 0.06, F(1,182) = 13.0, p = 0.0004). In conclusion, a significant, but complex, relationship was found between mercury and cortisol concentrations in hair from male, but not female, polar bears. PMID:26044932

  4. Community response to railway noise: A review of social surveys

    1988-01-01

    The many studies on the effects of railway noise on the neighbourhood differ greatly in their design, acoustic and sociological measurement and in their evaluation methods. As the influence of these factors on the sometimes differing results is not quantifiable, only qualitative results can be summarized and commented on. There are only a few studies with special emphasis on the effects of shunting yards, high-speed trains and urban train systems, and therefore only the results concerning free-flow railway traffic are summarized. The LAeq measured outside was shown in almost all the studies to be the most suitable for predicting general annoyance and most of the disturbance reactions compared with other acoustic data, e.g., peak level, pass-by frequency, etc. It is not possible to deduce from the studies in question a limiting value beyond which railway noise is no longer tolerable. Compared to other areas of interference, it is generally agreed that railway noise is at its most annoying in the area of communication. Sleep interference, on the other hand, was only seldomly mentioned and was not considered to be so serious. In addition to the noise level, non-acoustic factors such as attitude towards the railway, neighbourhood environment, etc., obviously considerably affect the annoyance reaction to railway noise too. The question of habituation to railway noise cannot be conclusively answered from the studies analyzed. At the same LAeq, railway noise gives rise to less annoyance than does road-traffic noise. These differences vary according to whether the reference time is day or night, the noise level range is high or low, and according to which annoyance and disturbance reaction is considered.

    We propose the application of a distributed optical fiber sensor based on stimulated Brillouin scattering, as an integrated system for safety monitoring of railway infrastructures. The strain distribution was measured dynamically along a 60 meters length of rail track, as well as along a 3-m stone arch bridge. The results indicate that distributed sensing technology is able to provide useful information in railway traffic and safety monitoring.

  6. Allocating Railway Platforms Using A Genetic Algorithm

    Clarke, M.; Hinde, C. J.; Withall, M. S.; Jackson, T. W.; Phillips, I. W.; Brown, S.; Watson, R.

    This paper describes an approach to automating railway station platform allocation. The system uses a Genetic Algorithm (GA) to find how a station’s resources should be allocated. Real data is used which needs to be transformed to be suitable for the automated system. Successful or ‘fit’ allocations provide a solution that meets the needs of the station schedule including platform re-occupation and various other constraints. The system associates the train data to derive the station requirements. The Genetic Algorithm is used to derive platform allocations. Finally, the system may be extended to take into account how further parameters that are external to the station have an effect on how an allocation should be applied. The system successfully allocates around 1000 trains to platforms in around 30 seconds requiring a genome of around 1000 genes to achieve this.

  7. Upper Mantle Structure and Azimuthal Anisotropy Beneath Hudson Bay From Rayleigh Wave Tomography

    2009-05-01

    Hudson Bay is a large intracratonic basin situated within the northern part of the Canadian Shield. The region is surrounded by Archean cratons, notably the Superior to the south and east and the Rae-Hearne to the north and west, and is largely underlain by the Paleoproterozoic Trans-Hudson orogen. Global and continental scale tomographic images of North America suggest that the seismological lithosphere of the Canadian Shield is at its thickest and fastest beneath Hudson Bay, but a regional-scale seismic study is necessary to provide sufficient detail to comprehend the structure and evolution of the region. Broadband seismograph stations were installed around the Hudson Bay region in 2006 and 2007 as part of the HuBLE (Hudson Bay Lithospheric Experiment) project. The combination of these stations with existing permanent and temporary seismograph deployments has resulted in a high-quality teleseismic data set for which detailed multi- disciplinary seismic studies of the region can be carried out. Fundamental-mode Rayleigh wave dispersion curves are calculated for >100 two-station paths. The data span a range of periods ˜15-- 220~seconds, corresponding to depths from the middle crust to the sublithospheric mantle. Comparison of the dispersion curves with those derived from global reference models and from the Canadian Shield average 'CANSD' suggests that the upper mantle beneath Hudson Bay can be characterised by a typical cratonic signature of anomalously high phase velocities. Many Hudson Bay dispersion curves exhibit higher phase velocities than those of 'CANSD', suggesting a seismically faster and thicker lithosphere than average for the Canadian Shield. 1D mantle models estimated from the two-station dispersion measurements show an average lithospheric thickness of ˜225~km, with velocities ˜4--6% above global reference values. A tomographic inversion is carried out to solve simultaneously for isotropic phase velocity heterogeneity and azimuthal anisotropy at

    2008-12-01

    HuBLE (Hudson Bay Lithospheric Experiment) is an international initiative to study the structure, dynamics and evolution of the Hudson Bay region. In particular, we seek to understand the interaction between the Archean cratons surrounding the region and the underlying Paleoproterozoic Trans-Hudson Orogen, which formed during the collision of the Superior and Churchill Provinces at 1.9-1.8 Ga. Global and continental- scale tomographic models indicate a thick, cold and refractory lithosphere beneath Hudson Bay. Most tomographic models suggest that this region is associated with the highest velocities and thickest seismological lithosphere of the Canadian Shield. The HuBLE project commenced in 2006, with the deployment of a number of telemetered broadband seismograph stations on the east and west coasts of Hudson Bay. Along with existing stations from the POLARIS/FedNor initiative in northern Ontario, and permanent Canadian stations, the deployment ringed Hudson Bay on three sides. A second phase of deployment in 2007, using non-telemetered broadband stations, completed the coverage of the region. A considerable number of large teleseismic earthquakes have been recorded by the array since its installation, and the data are generally of high quality. We measure Rayleigh wave phase velocities for paths crossing Hudson Bay, using the two-station cross-correlation method of Meier et al. (2004). Average phase velocity dispersion curves are constructed using data from multiple earthquakes along each path, resulting in a set of reliable dispersion measurements in the period range ~15--250~seconds. The data set therefore permits constraint of lithospheric shear wave velocity structure from mid-crustal to asthenospheric depths beneath the continent. Preliminary 1D shear wave velocity models of path-averaged structure are estimated using a smooth linearised inversion technique (Maupin & Cara, 1992). The models show a typically 'shield- type' signature, with a high

    As a result of PCB discharges from two manufacturing facilities located some 60 km upstream of Troy, N.Y., PCB's in sediments of the Hudson River were measured. The sediments contain PCB concentrations of approximately 10 ppm, some one to two orders of magnitude higher than levels previously recorded. A first-order PCB budget for Hudson River sediment samples and regional levels of PCB contamination prior to the large point-source discharges are examined.

    1994-01-01

    Methane emissions were measured by a static chamber technique at 39 sites along a transect from the James Bay coast at the southeastern tip of Hudson Bay to Kinosheo Lake, northwest of Moosonee, Ontario, Canada. These sites represented five major wetland ecosystems along a successional gradient from the coast inland. Measurements were made at ≈ 10-day intervals from early June to mid-August, and once in mid-September and mid-October 1990. Seasonal CH4 fluxes were small (<2 g m-2) at the recently emerged coastal marsh, coastal fen, tamarack fen, and interior fen ecosystems, except where there were shallow ponds and pools, which emitted 2-5 g CH4 m-2. At the more complex bog ecosystem locations, CH4 fluxes were small (0.3-2.0 g m-2) from hummock/hollow microtopography in the raised bogs and from the forested margin. The largest CH4 fluxes were recorded from the degrading peat sections forming shallow pools and the moss/sedge mats which were always close to saturation (1.8-16.6 g m-2). A deeper (1-m water depth) pool emitted less CH4 (1.4 g m-2). In terms of ecological succession along the transect, covering emergence over ≈ 4000 yr, CH4 emission rates increase from marsh to fen and bog, primarily through the development of peat degradation and the formation of moss/sedge lawns and pools. There were very weak statistical relationships at each site between the daily CH4 flux and peat temperature and water table. However, there was a significant (r2 = 0.44, p < 0.001) correlation between the seasonal CH4 flux and the mean position of the water table over the complete range of sites, emphasizing the overall importance of hydrology in determining CH4 flux. Laboratory incubation experiments were conducted to determine the capacity of the surface (0-20 cm depth) peat samples to produce CH4 anaerobically and consume CH4 aerobically. They revealed that many samples exhibited high CH4 consumption rates, suggesting that although CH4 production in the subsurface peat is high

    The thermal boundary layer at the surface of a river is constantly disrupted and renewed by physical processes associated with convection, turbulence, wind stress, heat flux, and other environmental factors. These disruptions cause temperature modulations in the surface layer which can be measured with an infrared (IR) sensor. Over the course of two ten-day periods in August and November of 2010, we imaged the Hudson River from atop a nearby cliff using a large-format, mid-wave IR sensor. Time series imagery was collected for 5 to 10 minute periods, every 30 minutes for the entirety of each experiment. In the field of view, several in situ instruments were mounted to a steel piling driven into the river bed. Above and below the water surface, an array of instruments were installed to measure heat flux, wind speed, air and water temperature, current velocity, humidity, radiance, and conductivity. In this analysis, we investigate the relationship between the temperature modulations present in the IR imagery, which are associated with coherent features advecting with the mean flow, and the environmental parameters measured from our in situ instruments. The IR imagery from these experiments show a diverse range of temperature modulation patterns, on scales of 20cm to several tens of meters, often masked by the presence of surface waves. At low grazing angles, the IR images of the water surface are comprised of a combination of emitted radiance from temperature modulations on the surface and reflected radiance from the sky above. To separate out the emitted signal from the reflected signal, we employ a Fourier space filtering technique to exclude the variance in the imagery due to the surface waves. We find the remaining emitted signal to be correlated with wind speed and the air-water temperature difference, and weakly or uncorrelated with stratification and mean current speed. We report on both the signal processing technique used to extract the emitted signal from

    The drivers of abrupt climate change during the Last Glacial Period are not well understood. While Dansgaard-Oeschger (DO) cycles are thought to be linked to variations in the strength of the Atlantic Meridional Ocean Circulation (AMOC), it is not clear how or if Heinrich Events—extensive influxes of icebergs into the North Atlantic Ocean that impacted global climate and biogeochemistry—are related. An enduring problem is the difficultly in dating iceberg rafted debris deposits that typically lack foraminifera. Here we present an ultra-high resolution record of methane from the West Antarctic Ice Sheet Divide ice core at unprecedented, continuous temporal resolution from 67.2-9.8 ka BP, which we propose constrains the timing of Heinrich events. Our methane record essentially mirrors Greenland ice core stable isotope variability across D-O events, except during Heinrich stadials 1, 2, 4 and 5. Partway through these stadials only, methane increases abruptly and rapidly, as at the onset of a D-O event but Greenland temperature exhibits no equivalent response. Speleothem records exhibit signatures of drought in the Northern extra-tropics and intensified monsoonal activity over South America at these times. We use a simple heuristic model to propose that cold air temperatures and extensive sea ice in the North, resulting from Heinrich events, caused extreme reorganization of tropical hydroclimate. This involved curtailment of the seasonal northerly migration of tropical rain belts, leading to intensification of rainfall over Southern Hemisphere tropical wetlands, thus allowing production of excess methane relative to a 'normal' Greenland stadial. We note that this mechanism can operate if AMOC is already in a slowed state when a Heinrich event occurs, as paleo-evidence suggests it was. Heinrich events and associated sea ice cover would therefore act to prolong the duration of this AMOC state. Our findings place the big four Heinrich events of Hudson Strait origin

Food items were present in 41% of Mohawk River samples and 11% of Hudson River samples; all Hudson River fish containing food were captured in small tributaries above the head of tide. Hudson River fish predominantly consumed zooplankton, while Mohawk River fish consumed benthic aquatic insects in large quantities, including Baetidae, Ephemeridae, and Chironomidae. Using stable isotope analysis and a mixing model, we found that fish collected later in the season had significantly decreased marine-derived C. Condition indices of later-season fish were equal to or greater than those of fish collected earlier in the season. Blueback herring in this system may face increased energy requirements as they migrate farther upstream during spawning runs, and feeding may provide energy subsidies needed to maintain fitness over their expanded migratory range. ??

  6. Chiral source apportionment of polychlorinated biphenyls to the Hudson River estuary atmosphere and food web.

    The New York/New Jersey Harbor Estuary is subject to significant contamination of polychlorinated biphenyls (PCBs) from numerous sources, including the historically contaminated Upper Hudson River, stormwater runoff and sewer overflows, and atmospheric deposition from PCBs originating from the surrounding urban area. However, the relative importance of these sources to the estuary's food web is not fully understood. Sources of PCBs to the estuary were apportioned using chiral signatures of PCBs in air, water, total suspended matter, phytoplankton, and sediment. PCBs 91, 95, 136, and 149 were racemic in the atmosphere of the estuary. However, the other phases contained nonracemic PCB 95 and to a lesser extent PCB 149. Thus, the predominant atmospheric source of these congeners is likely unweathered local pollution and not volatilization from the estuary. The similarity in chiral signatures in the other phases is consistent with dynamic contaminant exchange among them. Chiral signatures in the dissolved phase and total suspended matter were correlated with Upper Hudson discharge, suggesting thatthe delivery of nonracemic contaminated sediment from the Upper Hudson, not the atmosphere, controls phytoplankton uptake of some PCBs. Thus, measures to control PCB contamination in the Upper Hudson should be effective in reducing loadings to the estuary's aquatic ecosystem. PMID:17937297

  7. An integrated model for the fate and bioaccumulation of PCBs in the Hudson River estuary

    An integrated mass transport model with a five component food chain calculation was developed for predicting PCB accumulation in sediments, lower trophic species, and striped bass. The model was originally applied to PCB homologues and calibrated using field data through 1987. Results of this work indicated that, under a no-action alternative, 50% of the striped bass would be below the FDA limit of 2 {micro}g of PCB/g of fish (wet weight) by 1992 and 95% of the striped bass would be below the FDA limit by 2004. An initial post-audit evaluation of the model showed that predicted PCB concentrations in striped bass compared well to field measurements. Some deviation in predicted and observed concentrations however were noted in the upper portion of the estuary and are believed to be related to a transient PCB load from the upper Hudson. Further evaluations are presently being performed to addressed: (1) how have Hudson River sediments and striped bass responded to decreasing PCB loads; (2) what are the relative contributions of PCB loads from the upper Hudson, from contaminated estuarine sediments, and from wastewater discharges into the lower estuary on present PCB levels in fish; and (3) what role does congener structure play in determining the fate and bioaccumulation of PCBs in the Hudson River estuary.

    In 1984 the US Environmental Protection Agency (USEPA) completed a Feasibility Study on the Hudson River that investigated remedial alternatives and issued a Record of Decision (ROD) later that year. In December 1989 USEPA decided to reassess the No Action decision for Hudson River sediments. This reassessment consists of three phases: Interim Characterization and Evaluation (Phase 1); Further Site Characterization and Analysis (Phase 2); and, Feasibility study (Phase 3). A Phase 1 report was completed in August, 1991. The team then completed a Final Work Plan for Phase 2 in September 1992. This work plan identified various PCB fate and transport modeling activities to support the Hudson River PCB Reassessment Remedial Investigation and Feasibility Study (RI/FS). This talk provides a description of the development of a Probabilistic bioaccumulation models to describe the uptake of PCBs on a congener-specific basis in six fish species. The authors have developed a framework for relating body burdens of PCBs in fish to exposure concentrations in Hudson River water and sediments. This framework is used to understand historical and current relationships as well as to predict fish body burdens for future conditions under specific remediation and no action scenarios. The framework incorporates a probabilistic approach to predict distributions in PCB body burdens for selected fish species. These models can predict single population statistics such as the average expected values of PCBs under specific scenarios as well as the distribution of expected concentrations.

  14. Circulation and sediment transport in the vicinity of the Hudson Shelf Valley

    Harris, Courtney K.; Signell, Richard P.

    2000-01-01

    Sediment transport in the Hudson Shelf Valley and on the adjacent Long Island Shelf are evaluated using available data along with a three-dimensional wind-driven circulation model and a one-dimensional sediment transport model. Winds from the northwest drive currents up the Hudson Shelf Valley, while winds from the east produce weaker currents directed down the valley. Consistent with previous studies, sediment transport on the Long Island Shelf is dominated by resuspension during energetic wave events that are correlated with strong winds from the northeast, and net sediment flux is predicted to be towards the southwest along bathymetric contours. Transport of muddy sediments in the Hudson Shelf Valley, however, does not appear to be wave-dominated. These sediments are most likely to be resuspended by energetic currents driven by strong winds from the northwest that are not associated with energetic waves. The strong up-valley flows associated with these winds implies that net sediment flux along the Hudson Shelf Valley is up-valley.

  1. Multidimensional evaluation of soil pollution from railway tracks.

    PubMed

    Wierzbicka, Małgorzata; Bemowska-Kałabun, Olga; Gworek, Barbara

    2015-05-01

    Railway transport is a source of pollution to soils and living organisms by e.g. PAHs, PCBs, oil-derived products, pesticides and heavy metals. Soil toxicity evaluation requires chemical analyses, indicating the type and content of particular pollutants, as well as biological analyses, which allow assessing the reaction of organisms to these pollutants. This paper is focused on a multi-aspect evaluation of the degree of toxicity and pollution of soil in selected railway areas from north-eastern Poland by application of numerous biotests and chemical analyses. The soils were sampled on railway tracks from the following railway stations: Białystok Fabryczny, Siemianówka, Hajnówka, Iława Główna and Waliły. The most toxic soils occur on the railway tracks at Białystok Fabryczny and Siemianówka. They had a significant toxic effect on test organisms from various trophic levels. The contents of PAHs, PCBs, heavy metals, oil-derived hydrocarbons and pesticide residues were determined in the examined soils. In all cases the detected pollutants did not exceed the admissible levels. The highest content of oil-derived substances was noted in soils from Białystok Fabryczny and concentrations were moderate in soils from Siemianówka. Although the pollutants determined in soils from railway tracks did not exceed the admissible values, they had a toxic effect on numerous test organisms from different trophic levels. This suggests a synergistic effect of low concentrations (within the admissible levels) of several pollutants together, which resulted in a toxic effect on the organisms. Thus, there is a strong need of not only chemical, but also ecotoxicological analyses during the evaluation of environmental conditions. Based on data obtained from biological and chemical analyses, we concluded that railway transport may pose a hazard to the natural environment to a larger extent that hitherto expected.

  2. Low Latitude Pelagic Foraminifera Found in the Hudson River: Are They Hurricane Deposits?

    2011-12-01

    River sediment cores provide a record of past environmental changes through stacked layers of sediments. In core CD02-29A, recovered from the southern Hudson River, a significant number of tropical planktic foraminifer tests were found. Foraminifera were concentrated in sediment layers of low impedance, suggesting high carbonate content. Because modern planktic foraminifera are exclusively marine, their presence in Hudson sediments in the core was remarkable. We can think of only two mechanisms that could explain this observation: either living specimens are carried upriver with the daily tides, or storm surges carry large amounts of seawater and re-suspended marine sediment upriver. To test for the presence of living specimens in Hudson River water, plankton tow samples were collected during high tide at the Hudson Battery south of the sample site, and at Piermont Pier north of the sample site and no living foraminifera were found. In addition, oxygen isotope (δ18O) analyses reveal a marine composition but the large difference in δ18O between the two surface dwelling species Globigerinoides ruber (pink) and Globigerinoides sacculifer, picked from the same sediment layer, suggests re-suspension and mixing of marine sediment deposits. Because only planktic, tropical to subtropical foraminiferal assemblages were found, the Hudson River deposits differ from previously recorded storm deposits found on Long Island and in New Jersey. In particular, the foraminiferal assemblages contain up to 40% G. ruber (pink), suggesting a highly tropical signal from a location where abundances of G. ruber are very low. This data, in addition to the pulsed occurrence of tests in the sediment suggests that the introduction of planktic foraminifera into the Hudson River must be driven by rare events. We suggest that storm surges from rare high-intensity hurricanes most likely explain the presence of these tests in Hudson River sediments, possibly assisted by the Gulf Stream entraining

  3. A catastrophic meltwater flood event and the formation of the Hudson Shelf Valley

    The Hudson Shelf Valley (HSV) is the largest physiographic feature on the U.S. mid-Atlantic continental shelf. The 150-km long valley is the submerged extension of the ancestral Hudson River Valley that connects to the Hudson Canyon. Unlike other incised valleys on the mid-Atlantic shelf, it has not been infilled with sediment during the Holocene. Analyses of multibeam bathymetry, acoustic backscatter intensity, and high-resolution seismic reflection profiles reveal morphologic and stratigraphic evidence for a catastrophic meltwater flood event that formed the modern HSV. The valley and its distal deposits record a discrete flood event that carved 15-m high banks, formed a 120-km2 field of 3- to 6-m high bedforms, and deposited a subaqueous delta on the outer shelf. The HSV is inferred to have been carved initially by precipitation and meltwater runoff during the advance of the Laurentide Ice Sheet, and later by the drainage of early proglacial lakes through stable spillways. A flood resulting from the failure of the terminal moraine dam at the Narrows between Staten Island and Long Island, New York, allowed glacial lakes in the Hudson and Ontario basins to drain across the continental shelf. Water level changes in the Hudson River basin associated with the catastrophic drainage of glacial lakes Iroquois, Vermont, and Albany around 11,450 14C year BP (∼ 13,350 cal BP) may have precipitated dam failure at the Narrows. This 3200 km3 discharge of freshwater entered the North Atlantic proximal to the Gulf Stream and may have affected thermohaline circulation at the onset of the Intra-Allerød Cold Period. Based on bedform characteristics and fluvial morphology in the HSV, the maximum freshwater flux during the flood event is estimated to be ∼ 0.46 Sv for a duration of ∼ 80 days.

  4. Detection of Changes in Sediment Distribution in the Hudson River Estuary with Repeated Subbottom Profiling

    During the last decade, several major storms have impacted the US Atlantic coast, including tropical storm Sandy in 2013 and tropical storms Irene and Lee in 2012. These storms, in particular, had major impacts on the watershed of the Hudson River Estuary, resulting in changes in the delivery and distribution of sediments. While Sandy generated a large storm surge that mostly effected the lower estuary, Irene and Lee caused significant flooding in the upper estuary that delivered ~2.7 million tons of sediment to the Hudson River Estuary, which according to USGS estimates is an amount equal to three times the annual load of ~700,000-800,000 metric? tons (Wall et al. 2008; Ralston et al., 2013). Here we report results from high-resolution Chirp subbottom surveys conducted in selected areas of the Hudson River in 2014. Areas were selected with the goal of investigating changes in the sediment deposition and storage in the Hudson River as a result of these events. The new survey lines were acquired following the tracks of earlier subbottom profiles that were collected as part of the Hudson River Benthic Mapping Project in the early 2000s, i.e. before the storms of 2012 and 2013, in a dense grid of subbottom profiles. We then compared these co-located profiles to determine changes between the profiles and to map out the spatial distribution of increased deposition in the selected areas. In several places, the data show clear increases of the thickness of depositional layers of over 0.25 m while in other areas these changes are less clear. Changes based on sub-bottom data will be compared to results obtained on sediment cores taken from the same areas. Preliminary analysis of the sediment cores indicates clear layers of recent sediments in some areas that correspond to the results of the subbottom analysis.

  13. On the tracks of trauma: railway spine reconsidered.

    PubMed

    Harrington, Ralph

    2003-08-01

    The nineteenth-century medical condition known as "railway spine" has recently received considerable attention from medical historians, particularly historians of psychiatry and related fields. An historical interpretation has developed which traces the origins of "modern" psychodynamic medicine to the responses of nineteenth-century medical practitioners to railway spine. This interpretation characterizes the debates over railway spine as being between adherents of "soma" (i.e. constrained by "traditional" Victorian medical thought) and "psyche" (i.e. looking forward to "modern" psychological approaches). This article argues that this conflict is too sharply drawn and produces a teleologically-driven and misleading impression of the real significance of railway spine. This condition was seen from first to last as an organic disorder, and medical/medico-legal debates over its nature were concerned with the character of the organic processes at work, not with seeking to overturn organic explanations altogether. This has important consequences for historical understanding of the place of railway spine in the emergence of twentieth-century conceptions of traumatic disorder. PMID:14518477

  14. Stiffness of Railway Soil-Steel Structures

    NASA Astrophysics Data System (ADS)

    Machelski, Czesław

    2015-12-01

    The considerable influence of the soil backfill properties and that of the method of compacting it on the stiffness of soil-steel structures is characteristic of the latter. The above factors (exhibiting randomness) become apparent in shell deformation measurements conducted during construction and proof test loading. A definition of soil-shell structure stiffness, calculated on the basis of shell deflection under the service load, is proposed in the paper. It is demonstrated that the stiffness is the inverse of the deflection influence function used in structural mechanics. The moving load methodology is shown to be useful for testing, since it makes it possible to map the shell deflection influence line also in the case of group loads (concentrated forces), as in bridges. The analyzed cases show that the shell's span, geometry (static scheme) and the height of earth fill influence the stiffness of the structure. The soil-steel structure's characteristic parameter in the form of stiffness k is more suitable for assessing the quality of construction works than the proposed in code geometric index ω applied to beam structures. As shown in the given examples, parameter k is more effective than stiffness parameter λ used to estimate the deformation of soil-steel structures under construction. Although the examples concern railway structures, the methodology proposed in the paper is suitable also for road bridges.

    2014-05-01

    A methodology for the simulation of track settlement in railway turnouts (switches and crossings, S&C) is presented. The methodology predicts accumulated settlement for a given set of traffic loads using an iterative and cross-disciplinary procedure. The different modules of the procedure include (I) simulation of dynamic vehicle-track interaction in a turnout applying a validated software for multibody vehicle dynamics considering space-dependent track properties, (II) calculation of load distribution and sleeper-ballast contact pressure using a detailed finite element model of a turnout that includes all of the rails (stock rails, switch rails, closure rails, crossing nose, wing rails and check rails), rail pads, baseplates and sleepers on ballast, (III) prediction of track settlement for a given number of load cycles and (IV) calculation of accumulated track settlement at each sleeper and the resulting vertical track irregularity along the turnout which is used as input in the next step of the iteration. The iteration scheme is demonstrated by calculating the track settlement at the crossing when the studied turnout is exposed to freight traffic in the facing move of the through route.

    NASA Astrophysics Data System (ADS)

    Janssen, G.

    1996-05-01

    The social pressure to decrease noise nuisance caused by rail transport lines is growing rapidly. The solutions realized by the railway companies are often only effective locally and are specified without taking note of future European transport flows. In order to evolve their new policy the Dutch Railway company (NS) is developing a special purpose Geographical Information System. By means of this system it is possible to calculate the acoustic consequences of different future plans on a national or international scale. The input parameters of the system are the number of trains to be expected on the different lines, train speeds, train types, the noise nuisance law concerned, and the amount of sound reduction on specific trains and tracks. The acoustic consequences are quantified either as costs for noise barriers and sound-insulating measures in houses or as the area or number of people living within one specific equal noise level contour. The system gives policy-makers insight into the effects of certain sound reduction measures, of changes in the noise nuisance law and future transport flows. Results of studies show that the system can be a useful aid when making choices between investing in certain acoustic measures to be taken at the source or taking measures along the propagation path. In addition the system is useful as a monitoring system. Thus it is possible to quantify the effects of policy implementation and independent developments.

    Different sources of radioactive contamination contain characteristic and identifiable isotopic signatures, which can be used to study sediment transport. We focus on Pu-239, Pu-240, Np-237 and Cs-137, which are strongly bound to fine grained sediments. The Hudson River drainage basin has received contamination from at least three separate sources: 1) global fallout from atmospheric testing of nuclear weapons, which contributed Pu, Np and Cs; 2) contamination resulting from reactor releases at the Indian Point Nuclear Power Plant (IPNPP) located on the Hudson River Estuary ˜70km north of New York Harbor, where records document releases of Cs-137; 3) contamination resulting from activities at the Knolls Atomic Power Laboratory (KAPL) located on the Mohawk River, where incomplete records document releases of Cs-137 but no mention is made of Pu or Np. Here we report measurements of Pu isotopes, Np-237 and Cs-137 for a series of sediment cores collected from various locations within the drainage basin: 1) Mohawk River downstream of KAPL, 2) Hudson River upstream of its confluence with the Mohawk River, and 3) lower Hudson River at a location in close proximity to IPNPP. In addition, we present data from selected samples from two other lower Hudson River locations: One site located ˜30km downstream of IPNPP and another ˜30km upstream of IPNPP. By comparing the isotopic ratios Pu-240/Pu-239, Np-237/Pu-239, and Cs-137/Pu-239, measured in fluvial sediments to mean global fallout values, it is possible to identify and resolve different sources of non-fallout contamination. To date, isotopic data for sediments indicate non-fallout sources of Pu-239, Pu-240, and Cs-137; Np-237, however, appears to originate from global fallout only. Mohawk River sediments downstream of KAPL exhibit enrichments in Pu-239, Pu-240, and Cs-137 that are 7 to 20 times higher than levels expected from global fallout as indicated from Np-237. The elevated levels, non-fallout isotopic signatures

    The Lower Hudson River Basin study area covers 5,607 square miles and encompasses the part of the Lower Hudson River Basin that lies within New York plus the parts of the Housatonic, Hackensack, Bronx, and Saugatuck River Basins that are in New York. Twelve of the wells sampled in the Lower Hudson River Basin are completed in sand-and-gravel deposits, and 13 are completed in bedrock. Groundwater in the Lower Hudson River Basin was generally of good quality, although properties and concentrations of some constituents—pH, sodium, chloride, dissolved solids, arsenic, aluminum, iron, manganese, radon-222, total coliform bacteria, fecal coliform bacteria, Escherichia coli bacteria, and heterotrophic plate count—equaled or exceeded primary, secondary, or proposed drinking-water standards. The constituent most frequently detected in concentrations exceeding drinking-water standards (20 of 25 samples) was radon-222.

    Seventeen severe magnetic storms occurred in the period 2000 through 2005. In addition there was a major magnetic storm in March 1989. During each of these storms there was an anomaly in the operation of the system of Signalization, Centralization and Blockage (SCB) in some divisions of the high-latitude (˜58 to 64°N) Russian railways. This anomaly was revealed as false traffic light signals about the occupation of the railways. These signals on the Northern railways appeared exactly during the main phases of the strongest part of the geomagnetic storms characterized by high geomagnetic indices Dst and Kp (Ap). Moreover, the durations of these anomalies coincided with the period of the greatest geomagnetic disturbances in a given event. Geomagnetically induced currents (GICs) during significant strengthening of geomagnetic activity are concluded as the obvious reasons for such kind of anomalies.

  1. Condition Monitoring of Railway Vehicle Suspension Using Multiple Model Approach

    NASA Astrophysics Data System (ADS)

    Mori, Hirotaka; Tsunashima, Hitoshi

    This paper demonstrates the possibility to detect suspension failures of railway vehicles using a multiple-model approach from on-board measurement data. The railway vehicle model used in this study includes lateral and yaw motions of wheelsets and bogie, and the lateral motion of the vehicle body. These motions are measured by on-board sensors for lateral acceleration and yaw rate. The detection algorithm is formulated based on the interacting multiple-model (IMM) algorithm adding a method updating estimation model. The IMM method has been applied for detecting faults in vehicle suspension systems in a simulation study. The mode probabilities and states of vehicle suspension systems are estimated based on a Kalman filter (KF). This algorithm is evaluated in simulation examples. Simulation results indicate that the algorithm effectively detects on-board faults of railway vehicle suspension systems in realistic situation.

    In this paper, we propose a railway faults spreading model which improved the SIR model and made it suitable for analyzing the dynamic process of faults spreading. To apply our model into a real network, the accident causation network of "7.23" China Yongwen high-speed railway accident is employed. This network is improved into a directed network, which more clearly reflects the causation relationships among the accident factors and provides help for our studies. Simulation results quantitatively show that the influence of failures can be diminished via choosing the appropriate initial recovery factors, reducing the time of the failure detected, decreasing the transmission rate of faults and increasing the propagating rate of corrected information. The model is useful to simulate the railway faults spreading and quantitatively analyze the influence of failures.

    Passenger flow forecast is of essential importance to the organization of railway transportation and is one of the most important basics for the decision-making on transportation pattern and train operation planning. Passenger flow of high-speed railway features the quasi-periodic variations in a short time and complex nonlinear fluctuation because of existence of many influencing factors. In this study, a fuzzy temporal logic based passenger flow forecast model (FTLPFFM) is presented based on fuzzy logic relationship recognition techniques that predicts the short-term passenger flow for high-speed railway, and the forecast accuracy is also significantly improved. An applied case that uses the real-world data illustrates the precision and accuracy of FTLPFFM. For this applied case, the proposed model performs better than the k-nearest neighbor (KNN) and autoregressive integrated moving average (ARIMA) models. PMID:25431586

    Research on power line extraction technology using mobile laser point clouds has important practical significance on railway power lines patrol work. In this paper, we presents a new method for automatic extracting railway power line from MLS (Mobile Laser Scanning) data. Firstly, according to the spatial structure characteristics of power-line and trajectory, the significant data is segmented piecewise. Then, use the self-adaptive space region growing method to extract power lines parallel with rails. Finally use PCA (Principal Components Analysis) combine with information entropy theory method to judge a section of the power line whether is junction or not and which type of junction it belongs to. The least squares fitting algorithm is introduced to model the power line. An evaluation of the proposed method over a complicated railway point clouds acquired by a RIEGL VMX450 MLS system shows that the proposed method is promising.

  8. Seismic imaging of the lithosphere beneath Hudson Bay: Episodic growth of the Laurentian mantle keel

    NASA Astrophysics Data System (ADS)

    2013-07-01

    The Hudson Bay basin in northern Canada conceals one of the major collisional zones of the Canadian Shield, the Trans-Hudson Orogen (THO), which marks the Paleoproterozoic collision between the Archean Superior and Western Churchill cratons at ˜1.9-1.8Ga. Improved knowledge of upper mantle structure beneath the region is essential to establish the nature of the THO, specifically whether Himalayan-style plate tectonics operated in Paleoproterozoic times. Detailed seismological constraints on lithospheric architecture are also required to advance our understanding of the mechanism and timing of keel formation. We use surface wave tomography to illuminate new details of the lithospheric architecture of the Hudson Bay region, resolving both seismic wavespeed and azimuthal anisotropy. Phase velocity maps are calculated from fundamental-mode Rayleigh wave dispersion curves, then used to construct a 3D model exploring upper mantle structure to depths of ˜300km. Fast shear wavespeeds suggest a lithospheric thickness varying from ˜180km to almost 280 km beneath the Hudson Bay region. The new study confirms previous inferences that there is no correlation between crustal ages and lithospheric thickness. Patterns of shear wavespeed and azimuthal anisotropy indicate a layered lithosphere. In the uppermost mantle, both the highest velocities and the anisotropic fast directions wrap around the Bay. This structure is likely related to the formation processes of the Paleozoic intracratonic basin. At greater depth (˜70-150km) we resolve two high-wavespeed cores separated by a relatively narrow near-vertical lower-velocity curtain. This internal architecture is suggested to result from the terminal phase of a modern-style plate-tectonic collision between the Archean Superior and Churchill cratons during the Trans-Hudson orogeny, entrapping juvenile Proterozoic material. The lower lithosphere (≥160km depth) has a relatively homogeneous wavespeed structure across the region

    A 400-km-long deep seismic reflection transect across northeastern Montana and northern North Dakota reveals the crustal-scale structural fabric of the Early Proterozoic Trans-Hudson orogen beneath the Williston basin. Comparison with deep seismic reflection data across the Canadian portion of the same orogen ˜700 km to the north reveals first-order similarities in crustal architecture but documents significant along-strike variation in orogenic evolution. Both transects display a broad crustal-scale antiform axial to the orogen. In the north, geologic data suggest that this antiform is cored by an Archean microcontinent. In the south, west dipping reflections on the western flank of the antiform extend from the upper crust to the uppermost mantle and truncate prominent subhorizontal lower crustal reflections of the Archean Wyoming craton. Within the Wyoming craton, the eastern limit of east dipping midcrustal reflections coincides with the subsurface age boundary between the craton and the Early Proterozoic Trans-Hudson orogen as interpreted from potential field and drill core data. On the basis of subsurface geochronologic data from the crystalline basement and by analogy with the Glennie domain within the exposed Trans-Hudson orogen in Canada, we suggest that the southern antiform is cored by an Archean crustal fragment that was caught up in the terminal collision of the Wyoming and Superior cratons during Hudsonian orogeny. The eastern side of the Trans-Hudson orogen is characterized on both seismic transects by predominantly east dipping crustal penetrating reflections. We interpret the easterly dip of these reflections as evidence that the Superior province was thrust westward over the interludes of the orogen during terminal collision. Although juvenile Early Proterozoic terranes characterize the exposed segment of the Trans-Hudson orogen in Canada, limited drill core information within the Dakota segment of the orogen shows a predominance of granulitic

    The paper presents the data of clinical and hygienic studies of railway cashiers' health. The main deleterious factors of their working conditions are poor microclimatic conditions, bacterial inoculation of the working area air, a forced working posture, and a high vocal load under mental stress. There is a significant prevalence of nervous, obstetric, gynecological, thyroid, and vocal diseases and oral dysbacteriosis among the workers of this professional group.

    The article covers prevalence of obstructive sleep apnea syndrome, its role in health disorders of workers engaged into railway safety. The authors analyzed present standards of occupational fitness in workers performing critically important operating activities and methods of occupational selection with possible obstructive sleep apnea syndrome. I stage recommendations are suggested in diagnosis of obstructive sleep apnea syndrome in workers engaged into railway safety. Obstructive sleep apnea syndrome appeared to threaten operators' activity, to cause accidents, to early disablement due to life-threatening complications, to unsuitability for the occupation due to diseases connected with obstructive sleep apnea syndrome (arterial hypertension, diabetes mellitus, metabolic syndrome, cardiac rhythm and conductivity disorders, obesity).

  12. The socio-environmental determinants of railway suicide: a systematic review

    2014-01-01

    Background Railway suicide has significant adverse impacts for the victims, their family and friends, witnesses to the incident, general public and train network. There is no previous review on the socio-environmental factors and railway suicide. The research question asked in this review was: ‘What socio-environmental risk and protective predictors are significantly associated with railway suicide?’ Methods The review searched Medline, PsycINFO, Web of Science and Scopus for English-language studies that assessed the associations between socio-environmental (i.e. geographical, physical, economic and social) factors and railway suicide from their inception to June 2013. It was reported based on the PRISMA Statement. Results Eleven studies met the inclusion criteria. They were categorised into railway environments (availability of railways and trains, accessibility to railways and familiarity with trains), population characteristics and impact of media reporting. Findings from ecological studies using population level railway suicide data suggested weak and inconsistent evidence for the first two categories. The evidence on the impact of media reporting was moderately strong, with irresponsible media reporting being associated with an increased risk of railway suicide. Conclusions There is a need for further research activity to strengthen evidence about socio-environmental risk factors for railway suicide. The focus of this research should be on the factors that determine individuals’ decisions of using the railway as a method of suicide, with the consideration of a range of geographical, physical, social, and economic factors.

    Experiments were carried out in an anechoic chamber using a 1:20 scale model of a high-speed train to determine the insertion loss of various forms of track-side noise barrier. All the barriers investigated had the upper edge level with the bottom of the train windows and were positioned as close as possible to the train, within the limitations of the structure gauge. They thus provided attenuation of noise from sources in the lower portion of the train, in the region of the rails and wheels. The measured performance of plane screens with rigid and sound-absorbing surfaces is compared with values predicted by standard prediction methods for railway noise and the results of a numerical model. The effect of barrier shape and absorptive surfaces upon screening performance is investigated. Results are presented in terms of the insertion loss of the peak SPL of the pass-by profile for a single bogie noise source and for the whole train, and also insertion loss based onLAeq,1 h . Results for these three measures show similar trends. For the conditions tested insertion loss values for all the screens were lower when the ground behind the barrier was absorbing than when the ground was rigid. The relative changes in insertion loss for the different forms of barrier were similar for the two ground types. Insertion loss values for rigid screens were between 6 and 10 dB lower than those for similar screens with complete sound absorbing surfaces. The application of absorbing areas on rigid screens significantly increases the insertion loss by between 3 and 6 dB. The least efficient screen was a corrugated barrier with a rigid surface. The most efficient screens tested were plane and curved barriers with absorbing surfaces and a multiple edge screen with a part-absorbing surface.

    1994-02-01

    Around 90 London Underground train drivers experience a person jumping or falling in front of their train each year. The majority of these incidents are suicides or attempted suicides. 76 drivers were interviewed in order to assess the range of responses to these incidents. The following psychometric instruments were used: Present State Examination (PSE9); Post-Traumatic Stress Disorder (PTSD) Interview; General Health Questionnaire (GHQ-28); Impact of Events Scale (IES); Post-Traumatic Symptom Scale; Recent Difficulties/Events scale; Perceived Stress Scale and Eysenck Personality Questionnaire (EPQ). When interviewed 1 month after the incident 13 (17.11%) drivers presented with PTSD. Diagnoses other than PTSD e.g. neurotic depression and phobic state were present in 24 (31.58%) drivers (including 12 of the 13 PTSD cases who had one additional diagnosis). On the basis of diagnoses three groups were identified: Group 1 drivers had PTSD and in most cases an additional PSE9 diagnosis; Group 2 drivers had a PSE9 diagnosis only; Group 3 drivers were not cases. 56 drivers were again interviewed 6 months after the incident to assess duration of caseness and/or symptoms and to identify any cases of delayed onset. Two drivers were still cases at 6 months (neurotic depression and phobic state), no driver presented with PTSD at 6 months. At 6 months there was a significant drop in symptom scores compared with measures taken at 1 month. These results suggest that although approximately one-third of drivers suffered a severe psychological reaction following a railway suicide, when interviewed again 6 months after the incident most drivers reported a marked reduction in symptoms.

  15. Annoyance and activity disturbance induced by high-speed railway and conventional railway noise: a contrastive case study

    PubMed Central

    2014-01-01

    Background High-speed railway (HR, Electrified railway with service speed above 200 km/h.) noise and conventional railway (CR, Electrified railway with service speed under 200 km/h.) noise are different in both time and frequency domain. There is an urgent need to study the influence of HR noise and consequently, develop appropriate noise evaluation index and limits for the total railway noise including HR and CR noise. Methods Based on binaural recording of HR and CR noises in a approximate semi-free field, noise annoyance and activity disturbance induced by maximal train pass-by events in China were investigated through laboratory subjective evaluation. 80 students within recruited 102 students, 40 males and 40 females, 23.9 ± 2.1 years old, were finally selected as the subjects. After receiving noise stimulus via headphone of a binaural audio playback system, subjects were asked to express the annoyance or activity disturbance due to railway noise at a 0-100 numerical scale. Results The results show that with the same annoyance rating (A) or activity disturbance rating (D), the A-weighted equivalent sound pressure level (LAeq) of CR noise is approximately 7 dB higher than that of HR noise. Linear regression analysis between some acoustical parameters and A (or D) suggests that the coefficient of determination (R2) is higher with the instantaneous fast A-weighted sound pressure level (LAFmax) than that with LAeq. A combined acoustical parameter, LHC = 1.74LAFmax + 0.008LAFmax(Lp-LAeq), where Lp is the sound pressure level, was derived consequently, which could better evaluate the total railway noise, including HR and CR noise. More importantly, with a given LHC, the noise annoyance of HR and CR noise is the same. Conclusions Among various acoustical parameters including LHC and LAeq, A and D have the highest correlation with LHC. LHC has been proved to be an appropriate index to evaluate the total railway noise, including both HR and CR. However

    Past discharge of PCBs into the Hudson River has resulted in contaminant concentrations of a few tenths of a microgram per liter in the water. Waterford is one of two large municipal users of the Hudson River for drinking-water supply. The treatment scheme at the Waterford plant, which processes approximately 1 million gallons per day, is similar to that of most conventional treatment plants except for the addition of powdered activated carbon during flocculation. Comparison of PCB concentrations in river water and intake water at the plant to concentrations in treated drinking-water samples indicates that purification processes remove 80 to 90 percent of the PCBs and that final concentrations seldom exceed 0.1 microgram per liter. No significant difference was noted between the removal efficiencies during periods of high river discharge, when PCBs are associated with suspended sediment, and low discharge, when PCBs are generally dissolved.

    Data on channel geometry of the Hudson River estuary at 125 cross sections between the Federal Dam at Troy and the norhtern limits of New York City (133 miles) are presented for use in hydraulic modeling, tidal studies, traveltime and water-quality studies, and other uses requiring knowledge of Hudson River channel properties. The data were obtained from field surveys of the estuary conducted by boat with a fathometer in 1966-69. Water-surface elevations were not recorded during the fathometer runs but were calculated in 1979 from information on tide variations in the estuary and from stage data collected at Albany and New York City. Topographic maps and field reconaissance were used to extend the ends of the cross sections beyond 100-year flood stage. Channel-configuration data are presented as perspective plots and in a table; also included are strip maps showing the location of the cross sections. (USGS)

    Plutonium-239,240 and plutonium-238 were determined in 59 Hudson River sediment dredge samples collected during 1973-77 in the vicinity of the Indian Point Nuclear Power Station. Acid leaching followed by solvent extraction, electrodeposition, and alpha-spectrometry were used to extract, purify, and quantitate plutonium isotopes present in these samples. Annual median plutonium-238/plutonium-239,240 isotopic activity ratios in surficial sediments were 0.032 (1973-74), 0.035 (1975), 0.042 (1976), and 0.040 (1977). The source of these nuclides in the estuary was identified by analysis of the sample isotopic activity ratios. On the basis of the sampling regimen and the methods used, it is concluded that no input, other than that of fallout, has contributed significantly to the plutonium burden in Hudson sediments.

    The distribution of Triclosan within the Hudson River Estuary can be explained by a balance among the overall effluent inputs from municipal sewage treatment facilities, dilution of Triclosan concentrations in the water column with freshwater and seawater inputs, removal of Triclosan from the water column by adsorption to particles, and loss to photodegradation. This study shows that an average water column concentration of 3+/-2 ng/l (in the lower Hudson River Estuary) is consistent with an estimate for dilution of average wastewater concentrations with seawater and calculated rates of adsorption of Triclosan to particles. An average Triclosan sediment concentration of 26+/-11 ng/g would be in equilibrium with the overlying water column if Triclosan has a particle-to-water partitioning coefficient of k(d) approximately 10(4), consistent with laboratory estimates.

    Storms Irene and Lee in 2011 produced intense precipitation and flooding in the U.S. Northeast, including the Hudson River watershed. Sediment input to the Hudson River was approximately 2.7 megaton, about 5 times the long-term annual average. Rather than the common assumption that sediment is predominantly trapped in the estuary, observations and model results indicate that approximately two thirds of the new sediment remained trapped in the tidal freshwater river more than 1 month after the storms and only about one fifth of the new sediment reached the saline estuary. High sediment concentrations were observed in the estuary, but the model results suggest that this was predominantly due to remobilization of bed sediment. Spatially localized deposits of new and remobilized sediment were consistent with longer term depositional records. The results indicate that tidal rivers can intercept (at least temporarily) delivery of terrigenous sediment to the marine environment during major flow events.

  1. Precambrian Plate Tectonics and the Formation of the Canadian Shield: Seismic Evidence from Hudson Bay

    The Canadian Shield is one of the largest exposures of Precambrian rocks on Earth. It is a mosaic of several Archean terranes that were brought together during a series of Paleoproterozoic orogens culminating in the so-called Trans-Hudson Orogen (THO), which is thought to have been similar to the Himalayan orogen in scale and nature. The tectonic evolution and lithospheric subdivisions of this region are poorly understood, but new seismic networks in northern Hudson Bay provide fresh information sources to place constraints on the Precambrian processes that formed and shaped it. Using data from a network of 12 broadband seismic stations in the northern part of Hudson Bay that complement existing POLARIS and CNSN networks in the region, we report on a combined study of seismic anisotropy, travel-time tomography, and receiver functions. While tomographic images reveal no clear seismological distinction between Archean and Proterozoic mantle, results from the study of seismic anisotropy show that much of the northern Hudson Bay region retains a strong signature of Archean-to-Paleoproterozoic tectonics - in particular the THO. The receiver function study also provides evidence in support of this 1.8 Ga orogenic event, but the simplicity of crustal structure in the oldest terranes as well as the scale of orogenic belts provides little evidence in support modern-day-style plate tectonics. When reviewed in light of age and compositional constraints from the geological record, our seismic observations point towards a secular change from non-plate tectonic deformation during the Paleo- to Mesoarchean evolving towards fully-developed modern-style plate tectonic interactions during the Paleoproterozoic.

    The use of ground penetrating radar (GPR) as a means to determine peak thickness and estimate peat volume in the Hudson Bay Lowlands of Canada is examined. Ground-based and airborne GPR data were acquired so as to extrapolate measurements to larger scales. While the ground-based measurements did an excellent job in determining peat depth, the airborne techniques did a fair job a low altitudes and demonstrated great promise with additional system engineering changes.

    We applied the Theory of Planned Behavior to help understand the relationships between environmental beliefs, support for ecosystem restoration actions, and willingness to pay (WTP) for restoration and protection goals in the Hudson River estuary, New York State, USA. We conducted a mail survey with 3,000 randomly-chosen local residents of the Hudson River estuary in the fall of 1999. As hypothesized, the broad ecosystem restoration goals of the Hudson River Estuary Action Plan were more strongly supported than the corresponding specific implementation actions. We found that beliefs and past behavior were better explanatory variables than sociodemographic characteristics for explaining people's support for ecosystem restoration actions and WTP for restoration and protection goals. Because ecosystem restoration goals appear to be more generally acceptable than specific restoration actions, proponents of restoration programs should not become complacent about the need for active public outreach and involvement even if initial restoration program discussions have been low in controversy. Efforts to assess and foster support for ecosystem restoration should be targeted toward audiences identified on the basis of beliefs and past behaviors rather than on sociodemographic characteristics.

    Remedial decision making at large contaminated sediment sites with bioaccumulative contaminants often relies on complex mechanistic models to forecast future concentrations and compare remedial alternatives. Remedial decision-making for the Hudson River PCBs Superfund site involved predictions of future levels of PCBs in Upper Hudson River (UHR) and Lower Hudson River (LHR) fish. This study applied model emulation to evaluate the impact of updated sediment concentrations on the original mechanistic model projections of time to reach risk-based target thresholds in fish in the LHR under Monitored Natural Attenuation (MNA) and the selected dredging remedy. The model emulation approach used a combination of nonlinear and linear regression models to estimate UHR water PCBs as a function of UHR sediment PCBs and to estimate fish concentrations in the LHR as a function of UHR water PCBs, respectively. Model emulation captured temporal changes in sediment, water, and fish PCBs predicted by the mechanistic model over the emulation period. The emulated model, using updated sediment concentrations and a revised estimate of recovery rate, matched the trend in annual monitoring data for white perch and largemouth bass in the LHR between 1997 and 2014. Our best predictions based on the emulated model indicate that the projected time to reach fish tissue risk-based thresholds in the LHR will take decades longer than the original mechanistic model projections.

    Since 1976, the commercial striped bass fishery in the Hudson River (NY) has been closed due to total polychlorinated biphenyl (t-PCB) concentrations that exceed the US Food and Drug Administration's advisory level of 2 {micro}g/g-wet weight. Extensive monitoring of Hudson River striped bass demonstrated much more variability in t-PCB levels among individual striped bass than could be explained by their age, sex, or lipid contents. To investigate the possible role of differential habitat use among subpopulations of striped bass in controlling their PCB exposures, 70 fish collected throughout the Hudson River estuary and Long Island Sound in 1994--1995 were analyzed for PCB congeners, and their lifetime migration behaviors were estimated by otolith microchemistry. The mean salinity encountered during the fish's last growth season prior to capture was inversely correlated with the t-PCB body burden. Striped bass permanently residing in fresh and oligohaline portions of the estuary adjacent to known PCB sources had elevated t-PCB levels and congeneric patterns with higher proportions of di-, tri-, and tetrachlorobiphenyls. Conversely, fish spending the majority of their life in more saline waters of the estuary or migrating frequently throughout the salinity gradient contained lower PCB levels composed of more highly chlorinated congeners. The approach used in this study allows habitat use to be incorporated into exposure assessments for anadromous fish species such as striped bass.

    Sediment deposition in urban estuaries is controlled by the interaction of human modifications and natural factors that include tides, fresh water inputs, bed morphology, sediment supply, and hydrodynamics. A key element of managing these estuaries is detailed understanding of sediment deposition and its driving processes. Using a combination of geophysical and geochemical analysis we establish a detailed inventory of 20 century deposition for most of the mud-dominated sections of the Hudson River. These data show variations between different segments of the Hudson River as well as strong local variations within each section, with depositional settings ranging from erosional to those accumulating at ~10 mm/year. Our work indicates that 170,000 - 250,000 metric tons of sediment are deposited annually in the areas studied, which is a significant portion of the estimated total annual sediment load of ~700,000 - 800,000 metric tons. This also suggests that some of the accumulated sediments are re-mobilized, e.g. during major storms. The observed patterns of deposition/erosion are primarily caused by natural conditions, but, in some parts, they are strongly influenced by human modifications of the estuary, such as dredging. In addition to improving our understanding of the sediment dynamic of the Hudson River, the observed distribution of sediment deposition is also an indicator for the occurrence of contaminants including heavy metals and PCB’s and thus a valuable tool for management decisions.

    This article reports on epidemiological features of railway traffic accidents and factors influencing traffic safety. An analysis of various kinds of railway traffic accidents over 30 years in Nanjing Railway Branch, Showed that railway traffic accidents have become a sort of modern social disease, and had particular epidemiological features. The peak of the epidemic curve appeared cyclically and had a close relation to social disturbances, Frequency of accident occurrence was the highest in the first season (period of spring transport) and the third season (period of high temperature) of the year thus most accidents happen in February and August. Most accidents occurred on Fridays and least on Mondays. Distribution of accidents had obvious "antenna" phenomenon in round graph which had a 24-hour cycle. Analysing the multiple factors influencing traffic safety, the results showed that the upper-limit-age of a train driver should not be more than 50 years old; The phenomenon "bathtub" between personage accident rate and age must be taken seriously. More attention should be paid to the psychological aspects when recruiting train drivers. In our country, it is urgent to set up standard of psychomovement function for choosing train locomotive drivers. Fatigue was one of the direct causes resulting in accident occurrences. No statistical correlation was found between biorhythm and accident occurrence. PMID:2036908

  11. Interaction between a railway track and uniformly moving tandem wheels

    2006-12-01

    Interaction among loaded wheels via railway track is studied. The vertical parametric oscillations of an infinite row of identical equally spaced wheels, bearing constant load and uniformly moving over a railway track, are calculated by means of Fourier series technique. If the distance between two consecutive wheels is big enough, then one can disregard their interaction via the railway track and consider every wheel as a single one. In this case, however, the Fourier series technique represents an appropriate computation time-saving approximation to a Fourier integral transformation technique that describes the oscillations of a single moving wheel. Two schemes are considered. In the first scheme, every wheel bears the same load. In the second one, consecutive wheels bear contrarily directed loads of the same magnitude. The second scheme leads to simpler calculations and so is recommended to model the wheel-track interaction. The railway track periodicity due to sleeper spacing is taken into account. Each period is the track segment between two adjacent sleepers. A partial differential equation with constant coefficients governs the vertical oscillations of each segment. Boundary conditions bind the oscillations of two neighbour segments and provide periodicity to the track. The shear deformation in the rail cross-section strongly influences the parametric oscillations. It also causes discontinuity of the rail centre-line slope at any point, where a concentrated transverse force is applied. Therefore, Timoshenko beam properties with respect to the topic of this paper are discussed. Interaction between a railway track and a bogie moving at moderate speed is studied. The study points to influence of the bogie frame oscillations on variation in the wheel-rail contact force over the sleeper span. The simplified bogie model considered includes only the primary suspension. A static load applied to the bogie frame centre presents the vehicle body.

    In 2004, spotted sandpipers (Actitis macularia) were studied on the Hudson River near Fort Edward south to New Baltimore, NY and on two river drainages that flow into the Hudson River. Concentrations of 28 organochlorine pesticides, 160 polychlorinated biphenyl (PCB) congeners, and 17 dioxin and furan (PCDD-F) congeners were quantified in eggs collected on and off the Hudson River. The pattern of organochlorine pesticides and PCDD-F congeners did not differ significantly between eggs collected on and off the Hudson River. In contrast, the pattern of PCB congeners differed significantly between the Hudson River and other rivers. Total PCBs were significantly greater in eggs from the Hudson River (geometric mean = 9.1 microg PCBs/g wet weight) than from the other two rivers (0.6 and 0.6 microg PCBs/g wet weight). Seven of 35 (20%) eggs exceeded 20 microg PCBs/g wet weight, the estimated threshold for reduced hatching in tree swallows (Tachycineta bicolor) and some raptor species; the maximum concentration was 72.3 microg PCBs/g wet weight. Models that predicted nest survival and egg success (the proportion of eggs hatching in a clutch if at least one egg hatched) as functions of contaminant levels were poorly distinguished from models that presumed no such associations. While small sample size could have contributed to the inability to distinguish among contaminant and no toxicant models, we cannot rule out the possibility that contaminant concentrations on the Hudson River were not sufficiently high to demonstrate a relationship between contaminant concentrations and reproductive success.

    Internationally accepted exposure-response relationships show that railway noise causes less annoyance than road traffic and aircraft noise. Railway transport, both passenger and freight transport, is increasing, and new railway lines are planned for environmental reasons. The combination of more frequent railway traffic and faster and heavier trains will, most probably, lead to more disturbances from railway traffic in the near future. To effectively plan for mitigations against noise and vibration from railway traffic, new studies are needed to obtain a better basis of knowledge. The main objectives of the present study was to investigate how the relationship between noise levels from railway traffic and general annoyance is influenced by (i) number of trains, (ii) the presence of ground borne vibrations, and (iii) building situational factors, such as orientation of balcony/patio and bedroom window. Socio-acoustic field studies were executed in residential areas; (1) with relatively intense railway traffic; (2) with strong vibrations, and; (3) with the most intense railway traffic in the country. Data was obtained for 1695 respondents exposed to sound levels ranging from L(Aeq,24h) 45 to 65 dB. Both number of trains and presence of ground-borne vibrations, and not just the noise level per se, are of relevance for how annoying railway noise is perceived. The results imply that, for the proportion annoyed to be equal, a 5 - 7 dB lower noise level is needed in areas where the railway traffic causes strong ground-borne vibrations and in areas with a very large number of trains. General noise annoyance was twice as high among residents in dwellings with balcony / patio oriented towards the railway and about 1.5 times higher among residents with bedroom windows facing the railway.

    Cratons are vast areas of continental lithosphere that have remained relatively intact and stable since the Precambrian. They tend to be underlain by deep roots, characterized by anomalously fast seismic velocities (˜3%), which tomographic images show can extend to depths of ˜350km. The process by which these roots are formed is presently not well understood, but is believed to be associated with the accretion and imbrication of subducted oceanic material during the Archean. In order to test hypotheses on Precambrian crustal and lithospheric evolution in the North American craton and its influence on the intracratonic Hudson Bay basin, we undertake a study of P-to-S receiver functions to obtain estimates of crustal thickness and Vp/Vs ratio. Our high quality data come from the POLARIS, CHASME and CNSN networks, and the recently deployed HuBLE-UK broadband network of ten stations presently recording in northern Hudson Bay. Receiver functions from stations on Archean basement exhibit a sharp Moho Ps phase and clear subsequent reverberations, in contrast to those in the Trans-Hudson, which show much more complexity. Our results indicate Moho depths in Archean domains are consistent with other cratons worldwide (35-40km), with significant crustal thickening occurring within the Proterozoic Trans-Hudson Orogen (up to 52km). Increased crustal thickness (>40km) is also seen on Baffin Island, another region dominated by Proterozoic geology. Variations in Vp/Vs ratio appear to characterise certain geological regions, with elevated values (>1.74) in the Hearne craton, northern Hudson Bay and Southern Baffin Island regions, possibly due to reworking during Hudsonian collision. The lowest Vp/Vs ratios (˜1.70) are found within the Rae Craton, indicative of a felsic to intermediate lower crust. Combining results from the H-κ analysis with the nature of the crust-mantle transition zone will provide insights into the composition of the lower crust, and also shed light onto

  16. Acoustic propagation in the Hudson River Estuary: Analysis of experimental measurements and numerical modeling results

    Underwater intrusion detection is an ongoing security concern in port and harbor areas. Of particular interest is to detect SCUBA divers, unmanned underwater vehicles and small boats from their acoustic signature. A thorough understanding of the effects of the shallow water propagating medium on acoustic signals can help develop new technologies and improve the performance of existing acoustic based surveillance systems. The Hudson River Estuary provides us with such a shallow water medium to conduct research and improve our knowledge of shallow water acoustics. Acoustic propagation in the Hudson River Estuary is highly affected by the temporal and spatial variability of salinity and temperature due to tides, freshwater inflows, winds etc. The primary goal of this research is to help develop methodologies to predict the formation of an acoustic field in the realistic environment of the lower Hudson River Estuary. Shallow water high-frequency acoustic propagation experiments were conducted in the Hudson River near Hoboken, New Jersey. Channel Impulse Response (CIR) measurements were carried out in the frequency band from 10 to 100 kHz for distances up to 200 meters in a water depth of 8-10 meters which formed the basis for experimental Transmission Loss (TL). CIR data was also utilized to demonstrate multi-path propagation in shallow water. Acoustic propagation models based on Ray Theory and Parabolic Equation methods were implemented in the frequency band from 10 to 100 kHz and TL was estimated. The sound velocity profiles required as input by acoustic propagation models were calculated from in-situ measurements of temperature, salinity and depth. Surface reflection loss was obtained from CIR data and incorporated into the acoustic propagation models. Experimentally obtained TL was used to validate the acoustic model predictions. An outcome of this research is an operational acoustic transmission loss (TL) forecast system based on the existing, Stevens New York

  17. Modeling power-plant impacts on multipopulation systems: application of loop analysis to the Hudson River white perch population

    The white perch population of the Hudson River suffers unusually high mortality due to impingement and entrainment at power plants. The long-term consequences of this mortality for the Hudson River ecosystem depend in part on interactions between the white perch population and its prey, competitors, and predators, many of which are themselves subject to mortality at power plants. Size multipopulation models were analyzed, using a technique known as loop analysis, to determine how patterns of interaction affect population responses to stress and to identify the parameters that have the greatest influence on those responses. These theoretical results, together with information on life history and vulnerability to power plants for Hudson River fish and macroinvertebrate populations, were used to assess the likely effects of power plant mortality on the white perch population and its prey, competitors, and predators. The results suggest that effects of interactions with other populations are insufficient to offset the effects of entrainment and impingement on the Hudson River white perch population. The results also suggest that if mortality imposed by power plants does cause a substantial decline in the white perch population, then piscivore populations in the Hudson River should not be noticeably affected, a complementary increase in the abundance of competitors that are relatively invulnerable to power plants should occur, and a shift in the distribution of biomass within the white perch population toward the older age classes should occur.

    In this paper, a new model is constructed for the causation analysis of railway accident based on the complex network theory. In the model, the nodes are defined as various manifest or latent accident causal factors. By employing the complex network theory, especially its statistical indicators, the railway accident as well as its key causations can be analyzed from the overall perspective. As a case, the “7.23” China—Yongwen railway accident is illustrated based on this model. The results show that the inspection of signals and the checking of line conditions before trains run played an important role in this railway accident. In conclusion, the constructed model gives a theoretical clue for railway accident prediction and, hence, greatly reduces the occurrence of railway accidents.

    Rubber elements are widely used in the railway industry in order to achieve vibration transmission requirements. Although they are critical components in railway vehicles, their modelling in the dynamic models of railway vehicles is usually relatively simple: it is usual to characterise them using a simple linear model formed by a spring and a viscous dashpot in parallel. In this paper the behaviour of typical rubber elements is analysed and a model that allows more accurately the prediction of its behaviour is proposed. The methodology to implement this model in railway simulation programs is also discussed.

    In 1932, the epidemic of cholera in China was serious, spreading to all provinces nationwide, causing heavy casualties. In order to prevent cholera epidemics spread along the railway line, the National Government Ministry of Railways and the local railway administration had taken all countermeasures, including the promulgation of epidemic prevention laws and regulations, quarantine, isolated check-up, disinfection, vaccination and even interruption of traffic. The measures of railway authorities had achieved a certain success. In August 1932, cholera epidemic began to subside gradually. PMID:27049743

    Optimizing train movement has a great significance for railway traffic. In this paper, based on the optimal velocity car-following model, we propose a new simulation model for optimizing train movement in railway traffic. Here a kind of single-track railway is considered. Our aim is to reduce the energy consumption of train movement and ensure the train being on time by controlling the velocity curve of train movement. The simulation results indicate that the proposed model is effective for optimizing train movement. In addition, some major characteristics of train movement can be well captured. This method provides a new way to optimize train movement in railway traffic.

    The capability to find individuals using CCTV cameras is important for surveillance applications at large areas such as railway stations, airports and shopping centers. However, it is laborious to track and trace people over multiple cameras post incident. In this paper, we describe the live demonstration of our interactive re-identification system in a railway station. The system performs real-time track generation in multiple cameras and live re-identification and refinding of suspects which was live demonstrated in Poland. The system allows fast interactive retrieval of an individual by showing only similar candidates. An operator can find the origin or destination of a person more efficiently, especially over large time and space intervals.

    As one of the most important transportation, the safety of railway is paid much attention to. The quality of wheel should be checked periodically, especially in high-speed application. Normally, Non Destructive Testing (NDT), such as ultrasonic inspection method, is applied on wheels to find the defect. A stationary automatic railway wheelset inspection system by using ultrasonic technique is described in this paper. The phased array ultrasonic technique and wheel defect inspection method is described in detail. Specially designed line is installed for wheelset transportation. Wheelset lifting and rotating device is used for wheelset loading, unloading and rotating. A steel frame with complicated mechanical structure and ultrasonic devices are designed for wheelset defect detecting. System ultrasonic performance, system working flow, system control networking, data processing and results displaying are also described in the paper. Now, the system is installed in Chinese EMU maintenance center for disassembled wheelset inspection and the safety of wheels is well protected.

    This paper presents a spatial decision support system for network design problems in which different kinds of projects can be built in stages over time. It was developed by the World Bank and China's Ministry of Railways to plan investment strategies for China's overburdened railway system. We first present a mixed-integer program for the single-period network design problem with project choices such as single or multiple tracks and/or electrification with economies of scale. Then, because such projects can be built all at once or in stages, we developed a heuristic backwards time sequencing procedure with a cost adjustment factor to solve the ``project staging'' problem. Other innovations include a preloading routine; coordinated modeling of arcs, paths, and corridors; and a custom-built GIS.

  7. A Fast Estimation Method of Railway Passengers' Flow

    NASA Astrophysics Data System (ADS)

    Nagasaki, Yusaku; Asuka, Masashi; Komaya, Kiyotoshi

    To evaluate a train schedule from the viewpoint of passengers' convenience, it is important to know each passenger's choice of trains and transfer stations to arrive at his/her destination. Because of difficulties of measuring such passengers' behavior, estimation methods of railway passengers' flow are proposed to execute such an evaluation. However, a train schedule planning system equipped with those methods is not practical due to necessity of much time to complete the estimation. In this article, the authors propose a fast passengers' flow estimation method that employs features of passengers' flow graph using preparative search based on each train's arrival time at each station. And the authors show the results of passengers' flow estimation applied on a railway in an urban area.

    In striped bass samples from the lower Hudson River and its estuary 2,3,7,8-tetrachlorodibenzo-p-dioxin (2,3,7,8-TCDD) was found at concentrations from 16 to 120 pg/g (ppt). Striped bass from two other locations (Rhode Island coastal waters and Chesapeake Bay, Maryland) had <5 ppt, 2,3,7,8-TCDD. The contaminant, 2,3,7,8-tetrachlorodibenzofuran (2,3,7,8-TCDF), was found in striped bass from all three locations with concentrations varying from 6 ppt in Chesapeake Bay to 78 ppt in the Hudson River. Results from a limited number of non-migratory fish (carp and goldfish) and sediments suggest that the upper Hudson River is not a source for 2,3,7,8-TCDD/2,3,7,8-TCDF contamination of striped bass.

    The Hudson River watershed spans 34,700 km2 predominantly in New York State, including agricultural, wilderness, and urban areas. The Hudson River supports many activities including shipping, supplies water for municipal, commercial, and agricultural uses, and is an important recreational resource. As the population increases within this watershed, so does the anthropogenic impact on this natural system. To address the impacts of anthropogenic and natural activities on this ecosystem, the River and Estuary Observatory Network (REON) is being developed through a joint venture between the Beacon Institute, Clarkson University, General Electric Inc. and IBM Inc. to monitor New York's Hudson and Mohawk Rivers in real-time. REON uses four sensor platform types with multiple nodes within the network to capture environmentally relevant episodic events. Sensor platform types include: 1) fixed robotic vertical profiler (FRVP); 2) mobile robotic undulating platform (MRUP); 3) fixed acoustic Doppler current profiler (FADCP) and 4) Autonomous Underwater Vehicle (AUV). The FRVP periodically generates a vertical profile with respect to water temperature, salinity, dissolved oxygen, particle concentration and size distribution, and fluorescence. The MRUP utilizes an undulating tow-body tethered behind a research vessel to measure the same set of water parameters as the FRVP, but does so 'synchronically' over a highly-resolved spatial regime. The fixed ADCP provides continuous water current profiles. The AUV maps four-dimensional (time, latitude, longitude, depth) variation of water quality, water currents and bathymetry along a pre-determined transect route. REON data can be used to identify episodic events, both anthropogenic and natural, that impact the Hudson River. For example, a strong heat signature associated with cooling water discharge from the Indian Point nuclear power plant was detected with the MRUP. The FRVP monitoring platform at Beacon, NY, located in the

  11. Role of cryptic amphibole crystallization in magma differentiation at Hudson volcano, Southern Volcanic Zone, Chile

    Hudson volcano (Chile) is the southern most stratovolcano of the Andean Southern Volcanic Zone and has produced some of the largest Holocene eruptions in South America. There have been at least 12 recorded Holocene explosive events at Hudson, with the 6700 years BP, 3600 years BP, and 1991 eruptions the largest of these. Hudson volcano has consistently discharged magmas of similar trachyandesitic and trachydacitic composition, with comparable anhydrous phenocryst assemblages, and pre-eruptive temperatures and oxygen fugacities. Pre-eruptive storage conditions for the three largest Holocene events have been estimated using mineral geothermometry, melt inclusion volatile contents, and comparisons to analogous high pressure experiments. Throughout the Holocene, storage of the trachyandesitic magmas occurred at depths between 0.2 and 2.7 km at approximately ~972°C (±25) and log fO2 -10.33-10.24 (±0.2) (one log unit above the NNO buffer), with between 1 and 3 wt% H2O in the melt. Pre-eruptive storage of the trachydacitic magma occurred between 1.1 and 2.0 km, at ~942°C (±26) and log fO2 -10.68 (±0.2), with ~2.5 wt% H2O in the melt. The evolved trachyandesitic and trachydacitic magmas can be derived from a basaltic parent primarily via fractional crystallization. Entrapment pressures estimated from plagioclase-hosted melt inclusions suggest relatively shallow levels of crystallization. However, trace element data (e.g., Dy/Yb ratio trends) suggests amphibole played an important role in the differentiation of the Hudson magmas, and this fractionation is likely to have occurred at depths >6 km. The absence of a garnet signal in the Hudson trace element data, the potential staging point for differentiation of parental mafic magmas [i.e., ~20 km (e.g., Annen et al. in J Petrol 47(3):505-539, 2006)], and the inferred amphibolite facies [~24 km (e.g., Rudnick and Fountain in Rev Geophys 33:267-309, 1995)] combine to place some constraint on the lower limit of depth of

  13. Predicting surface vibration from underground railways through inhomogeneous soil

    NASA Astrophysics Data System (ADS)

    Jones, Simon; Hunt, Hugh

    2012-04-01

    Noise and vibration from underground railways is a major source of disturbance to inhabitants near subways. To help designers meet noise and vibration limits, numerical models are used to understand vibration propagation from these underground railways. However, the models commonly assume the ground is homogeneous and neglect to include local variability in the soil properties. Such simplifying assumptions add a level of uncertainty to the predictions which is not well understood. The goal of the current paper is to quantify the effect of soil inhomogeneity on surface vibration. The thin-layer method (TLM) is suggested as an efficient and accurate means of simulating vibration from underground railways in arbitrarily layered half-spaces. Stochastic variability of the soil's elastic modulus is introduced using a K-L expansion; the modulus is assumed to have a log-normal distribution and a modified exponential covariance kernel. The effect of horizontal soil variability is investigated by comparing the stochastic results for soils varied only in the vertical direction to soils with 2D variability. Results suggest that local soil inhomogeneity can significantly affect surface velocity predictions; 90 percent confidence intervals showing 8 dB averages and peak values up to 12 dB are computed. This is a significant source of uncertainty and should be considered when using predictions from models assuming homogeneous soil properties. Furthermore, the effect of horizontal variability of the elastic modulus on the confidence interval appears to be negligible. This suggests that only vertical variation needs to be taken into account when modelling ground vibration from underground railways.

    Recent studies suggest that professional exposure to Extremely Low Frequency-Electro Magnetic Field (ELF-EMF) can increase the risk of sudden cardiac death. Aim of our work was to find predictive parameters of arrhythmic risk in a population of 28 railways drivers exposed to ELF-EMF. Our findings were that the exposure did not reduce HRV and did not increase the risk of arrhythmias. PMID:15750820

  11. Early proterozoic evolution of the saskatchewan craton and its allochthonous coyer, trans-hudson Orogen

    1998-01-01

    The composition, chronology, and structural relations of the Saskatchewan Craton and enveloping mylonitic rocks exposed in basement windows of the Glennie Domain, Trans-Hudson Orogen, have been determined by geochemical, geochronologic, and structural studies accompanying detailed field mapping. Basement windows lie along the hinge zone of a regional crustal culmination and consist mostly of 2.4-2.5 Ga felsic plutonic rocks enveloped by the Nistowiak Thrust. The Nistowiak Thrust is a folded, 1-2 km thick, upper amphibolite facie??s mylonite zone formed during emplacement of the Flin Flon-Glennie Complex across the Saskatchewan Craton. It is likely correlative to the Pelican Thrust, which envelops basement windows in the Hanson Lake Block -100 km to the east. An internal high strain zone within the overlying nappe pile, the Guncoat Thrust, is composed primarily of mylonitized porphyroclastic pelitic and psammitic migmatites. U-Pb geochronological results suggest calc-alkaline plutonism from 1889-1837 Ma, thrust stacking, peak metamorphism and associated anatexis between 1837 and 1809 Ma, isotopic closure of titanite at 1790-1772 Ma, and intrusion of late granitic rocks at 1770-1762 Ma. This is in agreement with ages from the Hanson Lake Block, and La Ronge, Kisseynew, and Flin-Flon domains in Saskatchewan and Manitoba, and from the Ungava-Baffin portion of Trans-Hudson Orogen, suggesting broadly synchronous thermotectonic processes along a strike length of 2000 km. We speculate that the Saskatchewan Craton, rather than representing an exotic continental fragment, rifted from the Superior and/or Hearne Provinces at ca. 2.1 Ga and that the Trans-Hudson Orogen is an internal orogen. In this scenario the Maniwekan Ocean, developed between the Rae-Hearne and Superior cratons, opened and closed about similar pole(s) of plate motion. ?? 1998 by The University of Chicago.

  12. PCB accumulation in Hudson River pumpkinseed sunfish and bullhead: Influences of invertebrate prey

    SciTech Connect

    Feldman, R.S.

    1992-01-01

    Hudson River sediments are contaminated with PCBs, and these toxic compounds are also in the water and have accumulated in food chains. The relative importance of exposure by fish to contaminated water vs. contaminated prey was unknown. further, is was not known if difference in diet could influence fish PCB levels. Invertebrates and fish were sampled in different habitats to address these issues. Invertebrate communities differed in several ecological measures between two different plant beds, and among experimentally manipulated habitats in one plant bed. Communities often differed significantly in parameters such as total invertebrate density, densities of individual taxa, taxonomic richness and similarity, and size distributions; some taxa were also absent from one habitat but present in another. Total PCBs differed significantly for invertebrate communities between the two plant beds (9.4 vs. 31.4 [mu]g/g), and between some of the communities in the manipulated habitats (1.8 vs 5.3 [mu]g/g). These differences did not translate into difference in PCBs among fish that fed in the different habitats. However, bullhead had significantly higher levels than pumpkinseed (15.4 vs. 6.9 [mu]g/g). Yearling pumpkinseed that fed on Hudson River invertebrates had 5x the PCB levels of pumpkinseed exposed for the same period to the water but not to the prey, and 18x as much PCBs as fish unexposed to either Hudson River water or prey. Further, fish that fed on local prey had a higher proportion of high-Cl isomers than those exposed only to the contaminated water. Fish that fed in different habitats did not have different PCB levels. Thus, the role of diet needs further experimentation, but it is clear that local prey are the major route for PCB accumulation in yearling pumpkinseed.

  13. Diatoms as Proxies for Abrupt Events in the Hudson River Estuary

    The Hudson River estuary has been subject to many abrupt events throughout its history including hurricanes, droughts and pluvials. Hurricanes in particular are rare, discrete events that if fingerprinted can be used to develop better age models for Hudson River sediments. Proxies use observed physical characteristics or biological assemblages (e.g. diatom and foraminiferal assemblages) as tools to reconstruct past conditions prior to the modern instrumental record. Using a sediment core taken from the Hudson River (CDO2-29A), in New York City, drought and pluvial layers were selected based on Cs-137 dating while hurricane layers were determined from occurrences of tropical to subtropical foraminifera. Contrary to previous studies (Weaver, 1970, Weiss et al, 1978), more than sixty different diatom species have been identified using a scanning electron microscope (SEM). Cosmopolitan, hurricane and drought assemblages have begun to be identified after observing multiple layers (Table 1). Tropical foraminifera dominated by Globigerinoides ruber pink were also found in a hurricane layer that we infer was deposited during Hurricane Belle in 1976. More diatom abundance analyses and cataloged SEM pictures will provide further insight into these proxies.

  14. Polychlorinated biphenyls, dioxins, furans, and organochlorine pesticides in belted kingfisher eggs from the upper Hudson River basin, New York, USA.

    PubMed

    Custer, Thomas W; Custer, Christine M; Gray, Brian R

    2010-01-01

    Nesting belted kingfishers (hereafter kingfishers, Ceryle alcyon) were studied on the Hudson River near Fort Edward south to New Baltimore (NY, USA) and three nearby river drainages in 2004. Concentrations of 28 organochlorine pesticides, 160 polychlorinated biphenyl (PCB) congeners, and 17 dioxin and furan (PCDD-F) congeners were quantified in kingfisher eggs. The pattern of organochlorine pesticides and PCDD-F congeners did not differ significantly between 14 eggs collected from individual nests on the Hudson River and five eggs similarly collected on three other nearby rivers. In contrast, the pattern of PCB congeners in eggs collected on the Hudson River differed significantly from the other rivers. The differences in patterns of PCB congeners were associated with a higher representation of lower-numbered congeners on the Hudson River than the other rivers. The higher prevalence of the lower-numbered congeners and lower prevalence of the higher-numbered congeners is consistent with Aroclor 1016 and 1242 being the source of the PCBs on the Hudson River. Concentrations in a sample egg collected at each nest were compared to nest survival and egg success (the proportion of eggs hatching in a clutch if at least one egg hatched) of the remaining eggs in the clutch. Models that predicted nest survival and egg success as functions of contaminant levels were poorly distinguished from models that presumed no such associations. Small sample sizes could have contributed to the inability to distinguish among contaminant and no toxicant models. However, we cannot rule out the possibility that contaminant concentrations on the Hudson River were not sufficiently high to demonstrate a relationship between contaminant concentrations and reproductive success in kingfishers.

    Hudson Bay lies in the Precambrian core of North America, which is comprised of the Canadian Shield and contiguous platform regions. The region is underlain by one of the largest lithospheric keels on Earth; it is also the site of one of the largest negative geoid anomalies. We have deployed 10 broadband seismic stations in the northern part of the bay that complement the existing POLARIS, CHASME and CNSN network stations in the region. Here we present preliminary SKS shear wave splitting analyses and independent tomographic inversion of P- and S-wave travel-time data in order to: 1) understand better the origin and evolution of the Hudson Bay cratonic interior basins; 2) to illuminate possible relationships between the lithospheric keel, sub-lithospheric mantle flow and formation of the Hudson Bay basin; 3) to improve understanding of postglacial isostatic rebound; 4) to map the lithospheric structure of the Trans-Hudson orogen in a region characterized by extreme salient-reentrant geometry, possibly analogous to the western syntaxis of the Himalayan front. SKS delay times vary from 0.5-1.2s, which indicate a lithospheric-scale anisotropic layer up to 150km thick. However, SKS fast directions and preliminary tomographic images do not relate simply to the structural trends of the Trans Hudson Orogen and neighboring Archean terranes. Our work complements ongoing HuBLE studies that focus on receiver function analyses, dispersion analysis of teleseismic Rayleigh waves, and applications of ambient noise tomography that extract more information about lithospheric structure of the Hudson Bay basin.

    Fiber Bragg Grating (FBG) sensing technology was used to dynamically monitor multiple parameters of railway switch machine poles, including time of movement, direction and quantity of loading and locking force, and states of loading resistance. Ring shape FBG strain gauge and strain sensibilized methods significantly increased the monitoring sensitivity. Installing approaches adapted the harsh environment in railway application. The monitoring results showed that for a Siemens S700K switch machine, its pole pressured stroke took 5s. Maximum load: -5.9kN, average load: -3.3kN. Vibration caused by resistance exists, its period: 0.1s, range: 0.5kN~1.6kN. After the stroke, the locking force was kept at -0.6kN. In tensile stroke, it also took 5s. Maximum load: 6.8kN, average load: 5.5kN. Vibration period: 0.1s, range: 0.7kN~2kN. Locking force: 0.2 kN. This long-term and on-line detecting method could meet railway switch condition monitoring demands of more than 100,000 switch machines in this country.

  17. Red-light traffic enforcement at railway crossings

    Sidla, Oliver; Loibner, Gernot

    2012-01-01

    The observation and monitoring of traffic witih smart vision systems for the purpose of improving traffic safety has a big potential. Embedded loop sensors can detect and count passing vehicles, radar can measure speed and presence of vehicles, and embedded vision systems or stationary camera systems can count vehicles and estimate the state of traffic along the road. This work presents a vision system which is targeted at detecting and reporting incidents at unsecured railways crossings. These crossings, even when guarded by automated barriers, pose a threat to drivers day and night. Our system is designed to detect and record vehicles which pass over the railway crossing by means of real-time motion analysis after the red light has been activated. We implement sparse optical flow in conjunction with motion clustering in order to detect critical events. We describe some modifications of the original Lucas Kanade optical flow method which makes our implementation faster and more robust compared to the original concept. In addition, the results of our optical flow method are compared with a HOG based vehicle detector which has been implemented and tested as an alternative methodology. The embedded system which is used for detection consists of a smart camera which observes one street lane as* well as the red light at the crossing. The camera is triggered by an electrical signal from the railway as soon ss a vehicle moves over th this line, image sequences are recorded and stored onboard the device.

  18. Implementation of a piezoelectric energy harvester in railway health monitoring

    2014-03-01

    With development of wireless sensor technology, wireless sensor network has shown a great potential for railway health monitoring. However, how to supply continuous power to the wireless sensor nodes is one of the critical issues in long-term full-scale deployment of the wireless smart sensors. Some energy harvesting methodologies have been available including solar, vibration, wind, etc; among them, vibration-based energy harvester using piezoelectric material showed the potential for converting ambient vibration energy to electric energy in railway health monitoring even for underground subway systems. However, the piezoelectric energy harvester has two major problems including that it could only generate small amount of energy, and that it should match the exact narrow band natural frequency with the excitation frequency. To overcome these problems, a wide band piezoelectric energy harvester, which could generate more power on various frequencies regions, has been designed and validated with experimental test. Then it was applied to a full-scale field test using actual railway train. The power generation of the wide band piezoelectric array has been compared to a narrow-band, resonant-based, piezoelectric energy harvester.

    Railway local irregularities are a growing source of ground-borne vibration and can cause negative environmental impacts, particularly in urban areas. Therefore, this paper analyses the effect of railway track singular defects (discontinuities) on ground vibration generation and propagation. A vehicle/track/soil numerical railway model is presented, capable of accurately predicting vibration levels. The prediction model is composed of a multibody vehicle model, a flexible track model and a finite/infinite element soil model. Firstly, analysis is undertaken to assess the ability of wheel/rail contact models to accurately simulate the force generation at the wheel/rail contact, in the presence of a singular defect. It is found that, although linear contact models are sufficient for modelling ground vibration on smooth tracks, when singular defects are present higher accuracy wheel/rail models are required. Furthermore, it is found that the variation in wheel/rail force during the singular defect contact depends on the track flexibility, and thus requires a fully coupled vehicle/track/foundation model. Next, a parametric study of ground vibrations generated by singular rail and wheel defects is undertaken. Six shapes of discontinuity are modelled, representing various defect types such as transition zones, switches, crossings, rail joints and wheel flats. The vehicle is modelled as an AM96 train set and it is found that ground vibration levels are highly sensitive to defect height, length and shape.

    The processes that formed, thickened and thinned the early Earth's crust remain poorly known. The onset of modern plate tectonics, for example, could be as far back as the Hadean or as late as the Neoproterozoic. In many cratons, vertical processes are believed to have been dominant (dome-and-keel tectonics, e.g. Pilbara craton), while others are hypothesised to have formed by the progressive accretion of different terranes (e.g. Superior craton). The Hudson Bay region represents one of the largest areas of Precambrian geology on the planet, with ages spanning 2 billion years (3.9-1.8 Ga). The western Churchill province contains the predominantly Paleo- to Mesoarchean Rae domain and the Neoarchean Hearne domain, and is welded to the Superior craton by the Paleoproterozoic Trans-Hudson Orogen, a Himalayan scale feature which extends for more than 4500 km along strike. The Churchill has received comparatively little scientific investigation due to its remote location and harsh climate. In order to test hypotheses on crustal formation and evolution during the Precambrian, teleseismic receiver functions have been analysed for more than 30 stations located on the key geological features in the vicinity of Hudson Bay. Across the entire Rae domain, a dominantly felsic crust with a sharp Moho is observed. Little evidence exists to interpret the vast extent of the felsic crust in terms of subduction related processes. Within the granite-greenstone terranes of the Hearne domain, a more intermediate bulk composition and complex Moho signature may be representative of an oceanic affinity for the crust, suggesting accretionary processes acted there. In the Quebec-Baffin Island region, bulk crustal Vp/Vs ratios are dominated by effects associated with the Trans-Hudson Orogen, and appear to map out the first-order shape of the indenting lower-plate. Correlation between terrane age and receiver function-derived crustal structure suggests that the crust in northern Canada was

    The Paleozoic Hudson Bay intracratonic basin conceals a Paleoproterozoic Himalayan-scale continental collision, the Trans-Hudson Orogen (THO), which marks an important milestone in the assembly of the Canadian Shield. The geometry of the THO is complex due to the double-indentor geometry of the collision between the Archean Superior and Western Churchill cratons. Seismic observations at regional scale show a thick, seismically fast lithospheric keel beneath the entire region; an intriguing feature of recent models is a 'curtain' of slightly lower wavespeeds trending NE-SW beneath the Bay, which may represent the remnants of more juvenile material trapped between the two Archean continental cores. The seismic models alone, however, cannot constrain the nature of this anomaly. We investigate the thermal and compositional structure of the Hudson Bay lithosphere using a multi-observable probabilistic inversion technique. This joint inversion uses Rayleigh wave phase velocity data from teleseismic earthquakes and ambient noise, geoid anomalies, surface elevation and heat flow to construct a pseudo-3D model of the crust and upper mantle. Initially a wide range of possible mantle compositions is permitted, and tests are carried out to ascertain whether the lithosphere is stratified with depth. Across the entire Hudson Bay region, low temperatures and a high degree of chemical depletion characterise the mantle lithosphere. Temperature anomalies within the lithosphere are modest, as may be expected from a tectonically-stable region. The base of the thermal lithosphere lies at depths of >250 km, reaching to ~300 km depth in the centre of the Bay. Lithospheric stratification, with a more-depleted upper layer, is best able to explain the geophysical data sets and surface observables. Some regions, where intermediate-period phase velocities are high, require stronger mid-lithospheric depletion. In addition, a narrow region of less-depleted material extends NE-SW across the Bay

    Hudson Canyon is the largest submarine canyon on the US Atlantic continental margin. Our multidisciplinary study focuses on the canyon head from where it begins as an indentation in the outer continental shelf (water depth 100 m) to 75 km seaward along the canyon axis (water depth 2000 m). A shallow trough, the Hudson Shelf Valley extends about 185 km across the continental shelf and connects the mouth of the Hudson River where the river discharges into New York Bay to the head of the canyon. Our study comprises high-resolution bathymetry using Autonomous Underwater Vehicle (AUV) Eagle Ray (100 square km area),and delineation of interacting shelf and slope water masses using shipboard and AUV hydrocasts including water samples for methane analysis. The initial 10 km of the canyon head (axial depth 100 m to 300 m) bifurcates where it indents the outer shelf, with one branch aligned NW-SE with the Hudson Shelf Valley and a second branch aligned N-S along the shelf. The walls and floor of the NW-SE branch are smoothed by sediment accumulation and appear inactive in terms of sediment transport. The N-S branch is rough and appears active. Ravines orthogonal to the axis progressively increase in frequency and relief seaward through successive 10 km-long N-S and NW-SE trending sections of the canyon attaining a 1 km spacing. Two circular depressions (diameters 100 m and 300 m; relief c.15 m; depths 345 m and 390 m) occur at the base of the W wall of the N-S segment. The depressions may be collapse features related to gas discharge evidenced by a high methane anomaly (50 nM) detected in the adjacent canyon axis (water depth 421 m). Multiple layers of inter-leaved shelf (fresh) and slope (warm, salty) water masses were observed in the canyon head in summer 2007 and 2008. The dynamic interaction of these water masses is being studied in context of shelf-slope exchange and potential influence on canyon topography and ecosystems. We thank NOAA for support.

    A 73-day field study of in situ aerobic biodegradation of polychlorinated biphenyls (PCBs) in the Hudson River shows that indigenous aerobic microorganisms can degrade the lightly chlorinated PCBs present in these sediments. Addition of inorganic nutrients, biphenyl, and oxygen enhanced PCB biodegradation, as indicated both by a 37 to 55 percent loss of PCBs and by the production of chlorobenzoates, intermediates in the PCB biodegradation pathway. Repeated inoculation with a purified PCB-degrading bacterium failed to improve biodegradative activity. Biodegradation was also observed under mixed but unamended conditions, which suggests that this process may occur commonly in river sediments, with implications for PCB fate models and risk assessments.

  4. Geo-referenced social accounting with application to integrated watershed planning in the Hudson River Valley

    Nowosielski, Audra Ann

    Changing economic activity and patterns of human habitation have long been a cause of concern for the ecological health of the Hudson River and its tributaries. Today, economic development in the Hudson River Valley is often characterized as a battle between proponents of economy-wide growth and citizen groups concerned about the cumulative impact of incremental development on the watershed. Current development trends in the Hudson River Valley are driving the conversion of rural, agricultural and forestland to urban or industrial uses. This thesis is part of a larger study of the economic changes that lead to land use and environmental changes. It focuses specifically on the economic drivers of development in Dutchess County, an area of the lower watershed on the east bank of the Hudson, midway between New York City and the state capital of Albany. The objective was to engage the Dutchess County planning community in developing a planning model, the economic portion of which characterizes the economy with a Social Accounting Matrix (SAM) referenced to a Geographical Information System (GIS). The model was used to assess economic impacts of locally relevant development scenarios including a new IBM semiconductor plant, agro-tourism, and commuting behavior. These scenarios each discuss economic changes that have land use consequences. For example, a new IBM plant will likely instigate new residential development, agro-tourism offers a way to keep land in agricultural use, and the study of commuting behavior leads to insights on how residential growth may depend on commuting patterns, as well as information on the effects of second home communities. The final model will help stakeholders to visualize not only how economic shocks will change their communities, but also how these changes may lead to land use and cumulative environmental impact. Stakeholders will be able to visualize the trade-off between new economic growth and the possible loss of environmental

    Despite the large body of work on the work-family interface, hardly any literature has addressed the work-family interface in safety-critical settings. This study draws from social exchange theory to examine the effect of employees' strain-based work-to-family conflict on their supervisors' rating of their safety participation through job satisfaction. The sample consisted of 494 drivers from a major railway company in China. The results of a structural equation model revealed that drivers' strain-based work-to-family conflict negatively influences safety participation, and the relationship was partially mediated by job satisfaction. These findings highlight the importance of reducing employees' work-to-family conflict in safety-critical organizations. PMID:27423429

    As a large corridor project, plateau railway has multiple points and passes various sensitive environments along the railway. The determination of the scope of impact on ecological environment from railway construction is often controversial in ecological impact assessment work. Taking the Tangbu-Jiantang section of Li-Xiang Railway as study object, and using present land use map (1:10000) in 2012 and DEM as data sources, corridor cutting degree index ( CCI) and cumulative effect index of corridor (CCEI) were established by topology, buffer zone and landscape metrics methods. Besides, the ecological risk index used for railway construction was improved. By quantitative analysis of characteristics of the spatio-temporal change of landscape pattern and its evolution style at different spatial scales before and after railway construction, the most appropriate evaluation scale of the railway was obtained. Then the characteristics of the spatio-temporal variation of ecological risk within this scale before and after railway construction were analyzed. The results indicated that the cutting model and degree of railway corridor to various landscape types could be effectively reflected by CCI, and the exposure and harm relations between risk sources and risk receptors of railway can be measured by CCEI. After the railway construction, the railway corridor would cause a great deal of middle cutting effect on the landscape along the railroad, which would influence wood land and grassland landscape most greatly, while would cause less effect of edge cutting and internal cutting. Landscape indices within the 600 m buffer zone demonstrated the most obvious scale effect, therefore, the 600 m zone of the railway was set as the most suitable range of ecological impact assessment. Before railway construction, the low ecological risk level covered the biggest part of the 600 m assessment zone. However, after the railway construction, the ecological risk increased significantly, and

    This paper presents a view of the current state of monitoring track geometry condition from in-service vehicles. It considers technology used to provide condition monitoring; some issues of processing and the determination of location; how things have evolved over the past decade; and what is being, or could/should be done in future research. Monitoring railway track geometry from an in-service vehicle is an attractive proposition that has become a reality in the past decade. However, this is only the beginning. Seeing the same track over and over again provides an opportunity for observing track geometry degradation that can potentially be used to inform maintenance decisions. Furthermore, it is possible to extend the use of track condition information to identify if maintenance is effective, and to monitor the degradation of individual faults such as dipped joints. There are full unattended track geometry measurement systems running on in-service vehicles in the UK and elsewhere around the world, feeding their geometry measurements into large databases. These data can be retrieved, but little is currently done with the data other than the generation of reports of track geometry that exceeds predefined thresholds. There are examples of simpler systems that measure some track geometry parameters more or less directly and accurately, but forego parameters such as gauge. Additionally, there are experimental systems that use mathematics and models to infer track geometry using data from sensors placed on an in-service vehicle. Finally, there are systems that do not claim to measure track geometry, but monitor some other quantity such as ride quality or bogie acceleration to infer poor track geometry without explicitly measuring it.

    The distributions of CO2 system parameters in Hudson Bay, which not only receives nearly one third of Canada's river discharge, but is also subject to annual cycles of sea-ice formation and melt, indicate that the timing and magnitude of freshwater inputs play an important role in carbon biogeochemistry and ocean acidification in this unique Arctic ecosystem. This study uses basin-wide measurements of dissolved inorganic carbon (DIC) and total alkalinity (TA), as well as stable isotope tracers (δ18OH2O and δ13CDIC), to provide a detailed assessment of carbon cycling processes throughout the bay. Surface distributions of carbonate parameters reveal the particular importance of freshwater inputs in the southern portion of the bay. Riverine TA end-members vary significantly both regionally and with small changes in near-surface depths, highlighting the importance of careful surface water sampling in highly stratified waters. In an along-shore transect, large increases in subsurface DIC are accompanied by equivalent decreases in δ13CDIC with no discernable change in TA, indicating a respiratory DIC production on the order of 100 μmol/kg during deep water circulation around the bay. Based on TA data we surmise that the deep waters in the Hudson Bay are of Pacific origin.

    We analyzed 73 eels, collected in 2004 and 2005 above the head of tide in six Hudson River tributaries, for total PCBs, length, weight, age, and nitrogen stable isotope ratios (??15N). Mean total PCB concentration (wet weight basis) was 0.23 ppm ?? 0.08 (standard error), with a range of 0.008 to 5.4 ppm. A majority of eels (84) had concentrations below 0.25 ppm, and only seven eels (10%) had concentrations exceeding 0.5 ppm. Those eels with higher PCB concentrations were ???12 yr; there was a weak correlation of PCB concentration with ??15N and also with weight. Compared to recent (2003) data from the mainstem of the Hudson River estuary, these results indicate that tributaries are generally much less contaminated with PCBs. We hypothesize that those tributary eels with high PCB concentrations were relatively recent immigrants from the mainstem. Given concern over the possible adverse effects of PCBs on eel reproduction, these tributaries may serve as refugia. Therefore, providing improved access to upland tributaries may be critically important to this species. ?? 2008 Northeastern Naturalist.

    Tissue residues of total mercury (Hg), total polychlorinated biphenyls (PCBs), and lipid-based PCBs; plasma concentrations of endocrine biomarkers; and reproductive and histologic biomarkers were assessed in 460 carp (Cyprinus carpio), bass (Micropterus salmoides and Micropterus dolomieui), and bullhead (Ameiurus nebulosus) collected from eight sites across the Hudson River Basin in the spring of 1998 to determine if endocrine disruption was evident in resident fish species and to evaluate contaminant-biomarker interrelations. Total PCBs in bed sediments (maximum 2,500 ??g kg-1) could explain 64 to 90% of the variability in lipid-based PCB residues in tissues (maximum 1,250 ??g PCB g-lipid-1) of the four species. The 17??-estradiol to 11-ketotestosterone ratio, typically less than 1.0 in male fish and greater than 1.0 in females, exceeded 1.4 in all male largemouth bass and 35% of male carp and bullhead at one site 21 km downstream from a major PCB source. Endocrine biomarkers were significantly correlated with total Hg in female smallmouth bass and carp, and with lipid-based PCBs in males of all four species. Empirical evidence of endocrine modulation in blood plasma of male and female fish from sites with and without high PCB residues in bed sediments and fish tissues suggest that PCBs, Hg, or other contaminants may disrupt normal endocrine function in fish of the Hudson River. ??

    A 13.77 meter sediment core from Piermont Marsh, NY (41 00 N, 73 55W) records the local and regional vegetational and foraminiferal history of the Hudson Estuary. The sediments were sampled every 4 cm, which represents a decadal to century-scale resolution. Basal sediment dating is in progress, and the ll-m depth represents about 4000 years. Fluctuations in plant macrofossils and charcoal appear to indicate differences in salinlty and drought, suggesting major changes in climate. Scirpus, Salicornia, and high levels of charcoal seem to indicate drier/more saline conditions, while lack of these macrofossils and increases in Chara/Nitella, aquatic leaves, and very little charcoal suggests wetter conditions. Other macrofossils present include Carex, Juncus, Polygonum, Zanichellia, and Ruppia. High resolution AMS dating of plant macrofossils is in progress, and will be compared with sedimentation in Hudson River sediment cores nearby. Foraminiferal asssemblages from key intervals of the core will be presented. Human impact in the upper sediments is visible from the influx of grass seeds, primarily Phragmites, and the ragweed pollen rise.

    Maintaining and restoring connectivity are key adaptation strategies for biodiversity conservation under climate change. We present a novel combination of species distribution and connectivity modeling using current and future climate regimes to prioritize connections among populations of 26 rare species in New York's Hudson Valley. We modeled patches for each species for each time period and modeled potential connections among habitat patches by finding the least-cost path for every patch-to-patch connection. Finally, we aggregated these patches and paths to the tax parcel, commonly the primary unit of conservation action. Under future climate regimes, suitable habitat was predicted to contract or appear upslope and farther north. On average, predicted patches were nine times smaller and paths were twice as long under future climate. Parcels within the Hudson Highlands, Shawangunk Ridge, Catskill Mountains, and Harlem Valley had high species overlap, with areas upslope and northward increasing in importance over time. We envision that land managers and conservation planners can use these results to help prioritize parcel-level conservation and management and thus support biodiversity adaptation to climate change.

    The fate of oceanic methane and its impact on the global climate has been of particular interest to the global community. The potential for vast amounts of methane to be emitted from the seafloor into the atmosphere due to gas hydrate decomposition has been under scientific evaluation. However, despite the great extent of these geological reservoirs, much of the methane released from the seafloor in deep ocean environments does not reach the atmosphere. Once dissolved in ocean water, the emitted methane can be microbially converted to either carbon dioxide or assimilated to biomass. Here, we will present results from a research cruise to the Hudson Canyon, northern US Atlantic Margin, where we investigated changes in ocean water carbonate chemistry induced by the oxidation of methane released from gas seeps. We will be presenting high precision pH data as well as methane and DIC concentrations, natural stable isotopes, and methane oxidation rates collected inside and adjacent to the Hudson Canyon in the summer of 2014.

  17. Recent cooling along the southern shore of Hudson Strait, Quebec, Canada, documented from permafrost temperature measurements

    Permafrost temperatures from the surface down to about 20 m from 10 boreholes distributed around three villages on the coast of Hudson Strait (Salluit, Kangiqsujuaq, and Quaqtaq) were recorded and analyzed for the period 1988-1993. The results indicate that the permafrost has been regularly cooling along the southern shore of Hudson Strait. The observed trend in the order of 0.05{degrees}C yr{sup {minus}1} at the 20-m depth is consistent with the long-term regional cooling observed in air temperatures. It also coincides with an increased rate of cooling since the mid-1980s, which has been interpreted in the literature as being related to recurrent changes in the thermohaline circulation in the Arctic and North Atlantic oceans. The weak variation observed in the active-layer thickness at the study sites leads to the conclusion that the climatic cooling takes place principally through longer and colder winters. 23 refs., 7 figs., 5 tabs.

  18. Architecture and subsidence history of the intracratonic Hudson Bay Basin, northern Canada

    The Phanerozoic Hudson Bay Basin is a large intracratonic basin that is almost completely encircled by Precambrian rocks of the Canadian Shield. The preserved sedimentary succession is up to 2500 m thick and consists mainly of Upper Ordovician to Upper Devonian limestones, dolostones, evaporites and minor siliciclastics that were deposited in shallow marine conditions. Backstripping, based on new paleontological data and well correlations, reveals an irregular subsidence history marked by several periods of exhumation. In seismic data, the Hudson Bay Basin appears to have a relatively simple geometry, characterized by a lower sedimentary package cut by high-angle faults, overlain by a saucer-shape, essentially underformed upper sedimentary package. Normal (or transtensional) faults imaged on seismic reflection profiles provide clear evidence for crustal extension during deposition of the older sedimentary packages or slightly later, indicating that the basin is, at least partly, extensional in nature. However, significant changes in the depocenter location during the Paleozoic and variable exhumation values required by new maturation data indicate that other mechanisms influenced the subsidence/exhumation history of the basin. In particular, the influence of far-field events and dynamic topography transmitted by large-scale mantle flow in the continental interior (creating long-wavelength tilting and unconformities) is suspected but not yet proven.

    We conduct a stratigraphic paleoecological investigation at a Hudson River National Estuarine Research Reserve (HRNERR) site, Tivoli Bays, spanning the past 1100 years. Marsh sediment cores were analyzed for ecosystem changes using multiple proxies, including pollen, spores, macrofossils, charcoal, sediment bulk chemistry, and stable carbon and nitrogen isotopes. The results reveal climatic shifts such as the warm and dry Medieval Warm Period (MWP) followed by the cooler Little Ice Age (LIA), along with significant anthropogenic influence on the watershed ecosystem. A five-fold expansion of invasive species, including Typha angustifolia and Phragmites australis, is documented along with marked changes in sediment composition and nutrient input. During the last century, a ten-fold sedimentation rate increase due to land-use changes is observed. The large magnitude of shifts in vegetation, sedimentation, and nutrients during the last few centuries suggest that human activities have made the greatest impact to the marshes of the Hudson Estuary during the last millennium. Climate variability and ecosystem changes similar to those observed at other marshes in northeastern and mid-Atlantic estuaries, attest to the widespread regional signature recorded at Tivoli Bays.

    Chlorinated hydrocarbon chronologies of fine-grained sediments in NY Harbor indicate that decreasing concentration trends of total polychlorinated biphenyls which began in the late 1960s and early 1970s continued through the late 1980s. 1994 core top samples are currently being analyzed. This recent decline in total-PCB levels in NY harbor sediments can be described by a two component exponential function with separate terms representing the two primary sources of PCBs to this area. According to this function, transport from the Upper Hudson River dominated total PCB loading to NY Harbor in the 1970s, while local urban influxes were more important by the mid 1980s. The rate of decline in the geometric mean of lipid-based total-PCB concentrations in striped bass collected throughout the lower Hudson estuary between 1978 and 1990 is very similar to the trends observed in NY Harbor sediments. This similarity is consistent with the hypotheses that striped bass caught in the estuary obtain a significant fraction of their PCB burden in the NY Harbor area and contiguous estuarine waters and indicates that analyses of a relatively small number of dated sediment samples can provide an excellent indication of likely future trends of PCB levels in striped bass populations.
