  • glaciers
  • Airborne soot produced by wildfires and fossil-fuel combustion and transported to the remote McMurdo Dry Valleys of Antarctica contains levels of black carbon too low to contribute significantly to the melting of local glaciers, according to a new study by researchers supported by the National Science Foundation (NSF). (phys.org)
  • They conclude that further study of local carbon production and transport would help to understand the limited effects of local black carbon production on the Dry Valleys ecosystem, compared to the effects of windblown sediments, commonly deposited in the ablation regions of the glaciers, that have been shown to influence melt. (phys.org)
  • The black carbon deposited from long-range atmospheric transport in the snow accumulation regions of the glaciers is present in very low concentrations in the snow , too low to reduce the surface albedo of the glaciers ," Khan said. (phys.org)
  • Transport is also caused by glaciers as they flow, and on terrestrial surfaces under the influence of wind . (wikipedia.org)
  • These glaciers transport sediment and leave behind lateral moraines . (wikipedia.org)
  • accumulation
  • Samples taken from a snow pit in the accumulation region of the Commonwealth Glacier suggest the black carbon transported from beyond the continent is not sufficient to reduce the albedo-the glacier's ability to reflect light-to a degree that would increase melting. (phys.org)
  • fluid
  • Here, we show through leaf apoplastic fluid analysis and glucosinolate feeding experiments that two glucosinolate transporters, GTR1 and GTR2, essential for long-distance transport of glucosinolates in Arabidopsis, also play key roles in glucosinolate allocation within a mature leaf by effectively importing apoplastically localized glucosinolates into appropriate cells.

  • Sediment transport due to fluid motion occurs in rivers , oceans , lakes , seas , and other bodies of water due to currents and tides . (wikipedia.org)
  • regions
  • Aeolian sediment transport is common on beaches and in the arid regions of the world, because it is in these environments that vegetation does not prevent the presence and motion of fields of sand. (wikipedia.org)
  • passenger
  • Determining this figure for various modes of transport is possible through using passenger data sets for the population at risk (rather than the standard - yet inappopriate - resident population denominator common in rate calculations). (ucl.ac.uk)
  • understand
  • Profiling the victim population on public transport allows us to understand what these high-risk settings or socio-demographic characteristics are so that we can align crime reduction resources accordingly. (ucl.ac.uk)
  • Knowledge
  • Knowledge of sediment transport is most often used to determine whether erosion or deposition will occur, the magnitude of this erosion or deposition, and the time and distance over which it will occur. (wikipedia.org)
  • result
  • Its brownish color is mainly the result of the transported sediments taken upstream. (wikipedia.org)
  • Fluvial sediment transport can result in the formation of ripples and dunes , in fractal -shaped patterns of erosion, in complex patterns of natural river systems, and in the development of floodplains . (wikipedia.org)
  • This paper points out the need for emergency evacuation of air transports involved in accidents which result in cabin interiors becoming uninhabitable. (sae.org)
  • energy
  • The Mobility Model (MoMo) is a technical-economic database spreadsheet and simulation model that enables detailed projections of transport activity, vehicle activity, energy demand, and well-to-wheel greenhouse gas (GHG) and pollutant emissions according to user-defined policy scenarios to 2060. (iea.org)
  • important
  • Sediment transport is important in the fields of sedimentary geology , geomorphology , civil engineering and environmental engineering (see applications , below). (wikipedia.org)
  • show
  • 28th, 1:30 P.M., when passing Fort Delaware was invited by a gun from the port to show her colors, At 6:30 P.M., off Cape May, passed steam transport State of Georgia, bound South, with Col. ALLEN's regiment for Fort Monroe. (nytimes.com)
