These data are records collected from an automated weather station and four stand-alone tipping bucket rain gauges each with their own data logger that were in operation between February 2005 and December 2019 in the Badger Wash Study Area near Mack, Colorado as part of a larger project funded by the Bureau of Land Management. These files are hourly-interval data from the automated weather station with meteorological parameters of air temperature, relative humidity, wind speed, wind direction, wind gusts, photon flux density and rainfall as well as from a soil pit with temperature and soil moisture measurements at 5, 10, 20, 40, 60, 80 and 100 cm deep. The standalone tipping-bucket rain gauge data which records...

These data are a compilation of the characteristics of eddy sandbars, eddy sandbar areas and volumes measured between 1990 and 2015, and longitudinal metrics of the Colorado River in Grand Canyon National Park, Arizona. These data were used to evaluate the response of sandbars to controlled floods implemented in 1996, 2004, 2008, 2012, 2013, and 2014. These data were also used to characterize the variability in response among the monitoring sites and classify those monitoring sites into six characteristic groupings. These data were used to show that the characteristics of channel width, water-surface-elevation (stage) change between normal flows and controlled floods, and amount of vegetation cover are correlated...
These data were compiled to investigate differentiation in physiological activity varies through time for different functional groups. These include the seasonal progress of 13 plant species representing perennial C3 shrub, C3 grass, C4 grass, and annual forb functional groups of the Colorado Plateau, USA. These data can be used to test for differences in carbon assimilation strategies (SeasonalEcophyAciData) and how photosynthetic rates related to climate (SeasonalEcophyMonthlyData). Data can be arranged at the seasonal, annual, species-, or functional group-levels to compare multi-level processes.
These data were compiled to investigate the demographic, phylogeographic, and adaptation history of Hilaria jamesii. The data release consists of three tab delimited text files that may be used to infer population structure or putative adaptive loci (hija_adaptation_dataset.stru), relationships among sampling localities (hija_phylogeny_dataset.phylip), or genetic diversity statistics (hija_diversity_stats.vcf). All files record genetic variation on an individual (.stru and .vcf) or sampling locality (.phylip) level. The .vcf file contains all of the information contained in the other files, but the file structures vary based on the programs used for analysis. These files may be opened and edited in a text editor...
These data were compiled for evaluating river-reach level plant water use, or evapotranspiration (ET), and vegetation greenness, or Normalized Difference Vegetation Index (NDVI), in the riparian corridor of the Colorado River delta as specified under Minute 319 of the 1944 Water Treaty. The seven reach areas from the Northerly International Boundary (NIB) to the end of the delta at the Sea of Cortez were defined for research activities. Also, these seven reaches are being monitored under Minute 323 of the 1944 Water Treaty. Additionally, these data were compiled for evaluating restoration-level evapotranspiration and vegetation greenness data in Reach 2 and Reach 4, as specified under Minute 323 of the 1944 Water...
These tabular data were compiled to estimate abundance from paired physical capture and antenna detection data in closed, open, and robust design mark-recapture models. These data represent humpback chub capture histories in the Little Colorado River (LCR) and in the juvenile chub monitoring (JCM) reach of the Colorado River in the Grand Canyon, Arizona. The dataset includes multistate capture histories that describe both physical captures and antenna detections. The 'LCR chub' dataset was collected from long-term monitoring efforts by the US Fish and Wildlife Service in the lower 13.56 river km of the LCR (2009-2020), as well as a summer sampling trip conducted by US Geological Survey (2013-2020). Also, the LCR...
These data provide a comprehensive survey of peak-stage indicators along the Colorado River corridor between river mile (RM) 0 and RM 87 (see Figure 1 in the associated USGS-SIR). In 2008, the locations of peak-stage indicators in three short reaches downstream from RM 87 were measured using a handheld GPS unit (see Appendix 1 in the associated USGS-SIR). Total-station measurements were made using an established network of survey control that references the 2011 realization of NAD83 (NAD83 (2011)) (Kaplinski and others, 2017). The measurements were projected into the State Plane Coordinate System of 1983, Arizona central zone (FIPS zone 0202). Vertical positions are provided in both NAD83 ellipsoid heights and in...
The raster datasets in this release are maps of soil surface properties that were used in analyzing different approaches for digital soil mapping. They include maps of soil pH, electrical conductivity, soil organic matter, and soil summed fine and very fine sand contents that were created using both 2D and 3D modeling strategies. For each property a map was created using both 2D and 3D approaches to compare the mapped results.
These data were compiled to describe population reproductive structure of rainbow trout in the Colorado River downstream of Glen Canyon Dam, Arizona. Objective(s) of our study were to describe the population on reproductive structure of the rainbow trout population in Glen Canyon on the Colorado River and evaluate the accuracy of nonlethal methods (manual expression and ultrasonography) for assigning sex and reproductive phase. These data represent samples collected in 3 sampling trips fall in October to November 2018, February 2019, and April 2019. These data were collected in Glen Canyon, from Glen Canyon Dam to Lees Ferry on the Colorado River. Specifically, we sampled three reaches within Glen Canyon to represent...
These NetCDF data were compiled to investigate how rangelands in the western U.S. are limited by access to water. As a result, these ecosystems may be especially vulnerable to changes in water availability and drought as a result of climate change. This project utilized an ecosystem water balance model to quantify spatial and temporal patterns of rangeland ecological drought conditions under historical and future climate conditions. Water balance results were used to estimate several metrics that describe the seasonal timing and amount of moisture available for plant utilization in western rangelands. These data represent different aspects of water availability and drought. They are based on 1/16-degree gridded...
These data were compiled for the study: Divergent climate change effects on widespread dryland plant communities driven by climatic and ecohydrological gradients. The objectives of our study were to (1) describe how climate change will alter the biomass and composition of key plant functional types; (2) quantify the impacts of climate change on future functional type biomass and composition along climatic gradients; (3) identify if and which geographic locations will be relatively unaffected by climate change while others experience large effects; and (4) determine if there is consistency in climate change impacts on plant communities among a representative set of climate scenarios. These data represent geographic...
These data were compiled to improve our understanding of bat foraging along the Colorado River in Grand Canyon. Objectives of our study were to determine whether bat activity was influenced primarily by variation in prey availability relative to other environmental or geomorphic factors. These data represent 1,428 paired samples of bat activity and insect abundance calculated as catch rates collected on 611 sampling nights at 410 sampling sites throughout a 470 km segment of river. These data were collected from April to October in 2017-2020 at recreational camps along the Colorado River in Grand Canyon between Glen Canyon Dam and Pearce Ferry. These data were collected through a U.S. Geological Survey led community...
