These data are annual aeolian dust deposition calculations from vertical deposition at seven locations near the vicinity of Moab, Utah covering the period from 1999 to 2020. Data were collected by the U.S. Geological Survey Geosciences and Environmental Change Science Center (Denver, Colorado) and Southwest Biological Science Center (Moab, Utah) to "monitor sediment characteristics at sites selected to illuminate the relations between dust sources, present climate, and land use patterns" (Reheis 2003). The sites selected represent various land uses and land ownership including private land, multiple-use public lands, and restricted use National Parks. From 1999-2013 samples were sent to the Geosciences and Environmental...

Dust samples taken annually for five years from 55 sites insouthern Nevada and California provide an unparalleled sourceof information on modern rates of dust deposition, grain size,and mineralogical and chemical composition. The relations ofmodern dust to climatic factors, type and lithology of dustsource, and regional wind patterns shed new light on theprocesses of dust entrainment and deposition.A project to study modern dust deposition relative to soils insouthern Nevada and California was initiated in 1984 under theauspices of the Yucca Mountain Site Characterization Project(Interagency Agreement DE-AI08-78ET44802). The primary purposeof the dust-deposition project was to provide data on moderndust composition...
Dust storms have a number of impacts upon the environment including radiative forcing, and biogeochemical cycling. They transport material over many thousands of kilometres. They also have a range of impacts on humans, not least on human health. In recent years the identification of source areas for dust storms has been an important area or research, with the Sahara (especially Bodélé) and western China being recognised as the strongest sources globally. Another major development has been the recognition of the degree to which dust storm activity has varied at a range of time scales, millennial, century, decadal, annual and seasonal.

Eolian dust constitutes most of the pedogenic material in latePleistocene and Holocene soils of many arid regions. Comparison ofthe compositions and influx rates of modern dust with the eoliancomponent of dated soils at 24 sites in southern Nevada andCalifornia yields information on: (1) the composition and influxrate of dust in late Pleistocene and Holocene soils, (2) paleoclimateand its effects on the genesis of aridic soils, especially withregard to "dust events", (3) the timing and relative contribution ofdust from playa sources versus alluvial sources, and (4) the effectsof accumulation of fines in soil horizons. The A and B horizons ofsoils formed on gravelly alluvial-fan deposits in the study area aresimilar...
