Data

These CLIM-MET stations are meteorological/geological stations that is designed to function in remote areas for long periods of time without human intervention. These stations measure meteorological and wind-erosion parameters under varying climatic and land-use conditions to detect and describe ongoing landscape changes. These data represent multiple years of local detailed landscape...

These data were compiled to visualize the extent of Lake Powell at various elevation levels. These data represent water surface elevations for Lake Powell at levels critical to the operation of Glen Canyon Dam, at 5 foot intervals from the "Equalization Tier" ("Full Pool") to "Dead Pool", and at maximum and minimum elevations each water year throughout Glen Canyon Dam's operating history...

These data were compiled in support of the "Predicting the next high-impact insect invasion: Elucidating traits and factors determining the risk of introduced herbivorous insects on North American native plants" project supported by the U.S. Geological Survey John Wesley Powell Center for Analysis and Synthesis, as well as the "Forecasting high-impact insect invasions by integrating...

These data were compiled to provide gridded estimates of environmental suitability for pinyon-juniper species in western North America. These gridded suitability projections provide estimates of suitability under current climate conditions and future climate conditions and allow for visualization of suitability change across each species’ entire range. These data consist of gridded...

This dataset represents 505 campsites along the Colorado River in Grand Canyon with associated debris flow probabilities calculated for approximately a 100-year period (Griffiths and others, 2004) and geomorphic attributes mapped by the U.S. Geological Survey, Southwest Biological Science Center, Grand Canyon Monitoring and Research Center (GCMRC) (Hadley and others, 2018). The campsite...

This dataset represents 763 tributary canyons and/or watersheds adjacent to the Colorado River in Grand Canyon with associated debris flow probabilities from 2004. Also, these data include tributary canyon and/or watersheds to Glen Canyon and several smaller watersheds in Grand Canyon where debris flow data is currently unavailable. Historic probabilities of debris flow occurrence were...

These data were compiled as part of an effort to compare the relative data quality and modeling performance of bat data recorded with two different acoustic detectors. The objective of our study was to construct models evaluating the relative predictive quality of data collected by these two detectors. These data represent 48 paired sampling events where acoustic bat data was collected...

These data were compiled to model the area of exposed, bare sand along 168 km of the Colorado River between Glen Canyon Dam and Bright Angel Creek, Arizona. Objective(s) of our study were to develop and validate four models of exposed sand area for the study reach, respectively based on 1) single-day maxiumum river discharge, 2) multiple-day river discharge patterning, 3) field-observed...

These data were compiled to conduct a study on the effect of oil and gas development on dust emission potential in the Upper Colorado River Basin. The objectives of the study were to 1) assess the effect of oil and gas development on surface roughness, and 2) model the resultant effect of oil and gas development on sediment mass flux for a range of 10-m wind speeds and threshold wind...

These spatial data represent alluvial deposits of the Colorado River and tributary deposits adjacent to the Colorado River in Grand Canyon National Park. The map covers the river corridor from Lees Ferry, Arizona to the confluence with Diamond Creek 225 miles (362 km) downstream. The alluvial deposits of the Colorado River are mapped as either sand or gravel based on surface composition...

These data were compiled to support stranding risk modeling of young-of-year rainbow trout in Glen Canyon resulting from fluctuating flows from Glen Canyon Dam, called Trout Management Flows (TMFs). The objective of our study was to evaluate the stranding risk associated with different TMFs. We used the results of a 2-dimensional hydrodynamic model (Wright and others, 2024) as input to a...

The Buenos Aires National Wildlife Refuge (BANWR), along the Mexican border in southern Arizona, is host to a rich community of bird and mammal species, many of which rely on seed-bearing plants for sustenance. Native bees (Anthophila) provide pollination services vital to the reproduction of such plants, and some of Earth’s highest bee diversity has been documented within the broader...
