U.S. Geological Survey Open-File Report 03-138
Version 1.0
Several studies during the last 20 years have monitored and sampled modern dust deposition in the arid southwestern United States. These studies were conducted to (1) determine dust inputs to soil genesis; (2) provide data on modern dust composition and deposition rates to a computer model relating soil carbonate to paleoclimate; (3) monitor amount and composition of dust being deflated from the dry bed of Owens Lake, California, and (4) determine dust deposition at stations that monitor weather and wind erosion to help predict the effects of global climate change. The purpose of this report is to make available an up-to-date set of physical and chemical laboratory data and dust deposition rates for all these sites.
