Researchers from USD present findings at global conference Researchers from The University of South Dakota presented their findings at the 2008 Joint Annual Meeting of the Geological Society of America (GSA), Soil Science Society of America (SSSA), American Society of Agronomy (ASA), Crop Science Society of America (CSSA) and the Gulf Coast Association of Geological Societies, Oct. 5-9 at the George R. Brown Convention Center in Houston, TX. Mark R. Sweeney, Ph.D., assistant professor of earth sciences/physics at USD, and Christopher E. Markley, a USD student from Pierre, were scheduled to present during this first-ever joint meeting of these scientific societies, which celebrates the International Year of Planet Earth. Utilizing data from his research on the topic of Loess and Loess Soils, Sweeney presented â�?�?Using Soils, Tephras and Luminescence to Reveal the Holocene Record of Loess in the Pacific Northwestâ�? to discuss the latest phase of loess accumulation in the Palouse of the Pacific Northwest. Markley, meanwhile, uses data on sediments, geomorphology and quaternary geology in his presentation, â�?�?Compositional Variability of Dust-Producing Landforms in the Mojave Desert of Southern California,â�? which details three desert landforms capable of producing dust in the southern California portion of the Mojave Desert region. More than 10,000 scientists attended the 2008 Joint Meeting, which was hosted by the Houston Geological Society. Information about the 2008 conference is also available online at
