These data were compiled to assess time series data of aeolian sediment collections across varying climates, vegetation cover, and land uses on the Colorado Plateau. The objectives of our study were to interpret aeolian erosion and deposition processes and measure horizontal sediment flux over the span of two decades amid rapidly changing climate conditions and multiple land use changes within the study area. These data represent the seasonally accumulated horizontal sediment flux from different landscapes within the Colorado Plateau measured using Big Springs Number Eight (BSNE) dust samplers. These data were collected in Grand, San Juan, and Wayne County, Utah and Mesa Country, Colorado with sample collections ranging from 1998 to 2023. These data were collected by the United States Geological Survey, Southwest Biological Science Center, Canyonlands Research Station staff based in Moab, Utah during field sampling trips that occurred three times per year to collect sediment samples and process collected samples in the laboratory. These data can be used to understand long-term patterns of aeolian sediment flux within a range of Colorado Plateau ecosystems and investigate how land management decisions at certain sites has impacted aeolian sediment fluxes.

These data were compiled to measure airborne horizontal mass flux of sediments moved by wind across soils, climates, vegetation types, and land uses on the Colorado Plateau. Objectives of our study were to quantify spatial and temporal patterns in wind erosion and further our understanding of how soil and site setting, climate, and land uses are controlling wind erosion and horizontal mass flux. These data represent seasonal cumulative horizontal mass flux as measured using passive aspirated sediment traps, Big Spring Number Eight (BSNE) samplers. These data were collected in Grand and San Juan counties, Utah, and Mesa County, Colorado, USA between August 2017 and November 2020. These data were collected by the U.S. Geological Survey, Southwest Biological Science Center - Moab, UT, Research Station staff through field visits, that included physically collecting the sediment samples and processing them in the laboratory three times per year. These data can be used to represent the horizontal mass flux of the sampled plots averaged over the seasonal time steps of sampling, for the date ranges represented.

These data were compiled for monitoring and analyzing the amount of windblown (aeolian) sediment at 100 cm height near Moab, UT. Big Springs Number Eight (BSNE) field aeolian passive sediment traps are summarized by location and time period in shapefiles. Shapefiles also include attributes used to analyze patterns in the aeolian transport. Three different BSNE shapefiles represent 1) a network of BSNEs in a variety of rangelands, 2) BSNEs along downwind edges of unpaved roads where they run perpendicular to the dominant wind direction, and 3) long term BSNE sites used to test imporance of climate trends on aeolian transport. Also included in this data archive are raster files that were created from the BSNE data using statistical modeling approaches. These rasters represent predicted windblown sediment horizontal mass flux over the spring 2013 to spring 2015 time period.

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 Change Science Center in Denver to be processed. From 2014-2020 samples were processed at the Southwest Biological Science Center Canyonlands Research Station in Moab, Utah. The purpose of this data release is to make available annual aeolian dust deposition data collected 2009-2020 that have not been published. Data can be used to understand local and regional patterns of dust inputs from both dry and wet (rain and snow containing dust particles) deposition.

These data were compiled to show where significant river-sourced aeolian sediment deposits are present along the Colorado River downstream of Glen Canyon Dam in the Grand Canyon from Lee’s Ferry to the Diamond Creek confluence located 225 miles downstream. These deposits represent 118 active aeolian dunefields and were created by the Grand Canyon Monitoring & Research Center using field data and 20-cm pixel resolution, four spectral band imagery collected in 2013 (Durning and others, 2016) and validated using field observations and oblique photography. River-sourced sediment associated with these dunfields were excluded that were within the modeled inundation extent during a 1,274 m3/s (45,000 ft3/s) river flow scenario, representing the contemporary maximum controlled river flood release from Glen Canyon Dam. Dunefields are termed source-bordering aeolian dunefields and are comprised of wind deposited, river-sourced sand.

These data were compiled for assessing how geomorphic changes measured as topographic differences from repeat surveys represent measured and modelled estimates of aeolian sediment transport and dune mobility. Objective(s) of our study were to investigate whether topographic changes can serve as a proxy for aeolian transport and sediment mobility in dunefield environments. This was accomplished by relating topographic changes to modeled and observed estimates of sediment transport and dune mobility over months to decades within a partially vegetated dunefield starved of upwind sediment supplies. We specifically tested if topographic changes measured as net and total volume changes and topographic surface roughness differences provide evidence for intra-annual differences and decadal changes in sediment mobility for dune sand that is either currently bare, vegetated, or biocrust-covered. Lastly, these data were used as a framework for interpreting how aeolian transport and sediment mobility has changed for current land cover types over the preceding four decades. These data represent monthly topographic surveys and in-field sediment transport data collected between February 13, 2020 and December 16, 2020, piloted aerial imagery collected in 1984, 2002, 2009, 2013, and 2021, unoccupied aerial vehicle (UAV) imagery collected in March 2021, classification of land cover, and tabular summaries of topographic changes derived from these datasets. These data were collected between 1984 and 2021 within a small aeolian dunefield near the confluence of the Paria and Colorado Rivers, upstream of Grand Canyon National Park, Arizona. These data were collected by the U.S. Geological Survey. These data can be used to 1) to evaluate how dune surfaces with bare sand, sand with vegetated cover, and sand with biological soil crust cover (biocrust) change on a monthly time scale with differences in wind strength and 2) assess how the dunefield surface changed with vegetation loss and expansion over almost 4 decades. Additionally, these data could be used to assess detailed changes in landscape cover over monthly and decadal time scales.
