  • Studies on eolian dust in Greece
  • This paper deals with eolian deposits and dust storms in Greece. Statistics on episodes with atmospheric dust are extracted from meteorological data taken at a number of Greek weather stations. In addition eolian dust of probably Saharan origin
  • Effect of rock fragment eccentricity on eolian deposition of atmospheric dust
  • Aeolian dust ; Aeolian features ; Belgium ; Experimentation ; Geomorphometry ; Loess ; Wind speed
  • The aim of this study is to investigate the physical effects of rock fragment eccentricity on the dust deposition mechanism. This was examined in a wind tunnel. All data in this study refer to intial dust deposition (not accumulation), since only
  • wind velocities below the dust deflation threshold were tested.

  • Late Quaternary records of the atmospheric input of eolian dust to the center of the Chinese Loess Plateau
  • of the bulk loess sediment and to estimate the magnitude of the eolian dust component of the loess. Finally, they evaluate some geochemical proxy indicators related to variations in the Asian monsoon.
  • First, the AA. compare and contrast the particle-size distributions (PSDs) and elemental mass particle-size distributions (MSDs) of atmospheric dust and Chinese loess. Second, they use a statistical procedure to evaluate the elemental composition

  • Studies of recent dustfall in the Western and Eastern Mediterranean islands and mainlands give support to the hypothesis of eolian dust deposition from Africa. It is probably an important contribution to soil formation, slope wash and stream
  • sediments in the Mediterranean area. The quantitative role of African dust input, its history and distribution in time and space ought to be the subject of continued research.
  • Effect of rock fragments on eolian deposition of atmospheric dust
  • Aeolian dust ; Aeolian features ; Experimentation ; Rock ; Spatial variation ; Wind speed
  • The effect of rock fragment cover on the deposition of airborne dust was examined in a wind tunnel. Four parameters were studied: pebble size, pebble flattening, cover density and wind speed. The effect of these parameters on the deposition of dust
  • on the pebbles, on the deposition of dust between and underneath the pebbles, and on total dust deposition was measured separately. Air flow separation seems to play a primary role in the spatial distribution of dust deposition within a rock fragment field
  • Recent African dust deposition in West Germany―Sediment characteristics and climatological aspects
  • Aerosol ; Africa ; Atmospheric circulation ; Clay mineral ; Dust storm ; Eolian dust ; Eolian features ; Eolian transport ; Germany ; Grain size distribution;Granulometry ; Mineralogy ; Sahara ; Sahel
  • During the observation period from October 1987 to April 1989 nine deposition events of African mineral dust were recorded in Bochum, West Germany. This paper describes sedimentary characteristics of the fallout material and discusses critical
  • climatological aspects of African dust deposition in Europe.

  • Aeolian dust ; Atmospheric dynamics ; Climatology ; Dust storm ; Environment ; Land atmosphere interaction ; Temperature
  • The study presents some key factors influencing the formation, size and frequency of dust storms and describes the connection between temperature and eolian dust deposits. The role of dust storms and atmospheric dust in environmental processes
  • The use of topographic scale models in predicting eolian dust erosion in hilly areas: field verification of a wind tunnel experiment
  • Eolian erosion of natural dust in an area of 53 ha, situated in the northern Negev Desert, is investigated both in the wind tunnel (erosion simulations on a topographic scale model) and in the field. The wind tunnel results and the field results
  • show good agreement, indicating that wind tunnel simulations of eolian dust erosion on scale models of complex topography may predict, at least to an acceptable level, the erosion-sensitive areas in a hilly landscape of nearly uniform surface roughness.

  • Late Quaternary eolian deposition in central Italy
  • Aeolian dust ; Aeolian features ; C 14 dating ; Central Italy ; Geochronology ; Italy ; Lacustrine sediment ; Palaeo-environment ; Quaternary ; Tephrochronology
  • Records of eolian quartz from 2 continuous sediment sequences drilled in Lagaccione and Lago di Vico volcanic lakes in central Italy contribute to the knowledge of eolian deposition in the central Mediterranean during the last 100,000 years
  • . The chronology is based on C 14 and Ar/Ar dating and tephra analysis. Pollen data provide the paleoenvironmental framework and enable correlation between the cores. The main source of dust loading over the Mediterranean now, North Africa, may have played
  • an important role in dust supply throughout the last climatic cycle.

  • Aeolian dust ; Dune ; Ecosystem ; Grassland ; Nutrient ; Palaeosol ; Pedogenesis ; Quaternary ; Semi-arid area ; Surface deposits ; United States of America ; Utah
  • . The central aims are to characterize textural, mineralogical, and chemical properties that might indicate dust and nutrient contents of deeper substrates; determine the causes for variations in these properties that are presumed to elucidate changing
  • conditions of landscape stability in the study area as well as, perhaps, environmental change in dust-source areas; and assess the potential ecologic importance of these variations.
  • Aeolian dust ripples : their occurrence, morphometrical characteristics, dynamics and origin

  • In this paper, the main morphometric and dynamic properties of aeolian ripples formed in a wind tunnel during the deposition of natural, silt-sized dust particles over a flat horizontal surface are investigated. Two different (but counteracting
  • ) processes play a role in dust ripple dynamics : an aerodynamic process and an impact process, of which the first causes an upwind and the second a downwind migration of the ripples.

  • the fraction of this material derived from allochthonous eolian additions. Lake sediments representing deposition over the past few centuries were analyzed to determine whether dust deposition in the Uintas has been a long-term process, and if properties
  • of the modern dust differ from dust which accumulated prior to European settlement. Results indicate that alpine soils have been strongly influenced by long-term eolian deposition. The grain-size distribution, mineralogy, and geochemistry of lake sediments
  • indicate that dust has been accumulating in the Uintas for at least the last few centuries. Modern lake sediments are significantly enriched in elements indicative of upwind mining and agricultural activity, recording an anthropogenic change in dust
