Samples of aeolian (wind-transported) sediment were collected between 2003 and 2010 at multiple locations along the Colorado River corridor within Grand Canyon National Park, Arizona. At each site, sediment being actively transported by wind were collected using a set of four vertically stacked passive samplers (Big Spring Number Eight [BSNE] sand traps). Sediment samples were collected from the traps during site visits separated by days to months. Sediment sample weights were analyzed at the U.S. Geological Survey (USGS) Grand Canyon Monitoring and Research Center laboratory in Flagstaff, Arizona. Sediment-sample weights may be used to calculate rates of aeolian sediment transport at each location. The USGS gratefully acknowledges [...]
