These environmental raster covariate, geospatial vector data, and tabular data were compiled as input data for the Automated Reference Toolset (ART) algorithm. These data are a subset of all the environmental raster covariate data used in the ART algorithm.
Data on ambient-shade temperature, Normalized Difference Vegetation Index (NDVI) between February 1, 2010 and January 31, 2011 used for input onto a bioenergetics-based movement model for Galapagos turtles.
These data were used for the development and validation of the automated workflow for mechanistic segregation of geomorphic transport mechanisms presented in the manuscript "Geomorphic Process from Topographic Form: Automating the Interpretation of Repeat Survey Data in River Valleys."
Data were compiled or measured (depending on the trait) for 110 plant species which were documented in vegetation monitoring surveys in years 2012-2014 along the Colorado River through Grand Canyon National Park. New trait data were collected for specific leaf area, stem specific gravity, δ13C, δ15N, percent carbon and nitrogen, and carbon:nitrogen ratio.
DATA RELEASE - Channel Mapping of the Colorado River in Grand Canyon National Park, Arizona - May 2009, river miles 29 to 62
Bathymetric, topographic, and grain-size data were collected in May 2009 along a 33-mi reach of the Colorado River in Grand Canyon National Park, Arizona. Channel bathymetry was mapped using multibeam and singlebeam echosounders, subaerial topography was mapped using ground-based total-stations, and bed-sediment grain-size data were collected using an underwater digital microscope system.
DATA RELEASE - Southwestern Riparian Plant Trait Matrix, Colorado River, Grand Canyon, Arizona, 2014 - 2016
This dataset contains information on the physical traits and environmental tolerances of plant species occurring along the lower Colorado River through Grand Canyon. Data for the matrix were compiled from published scientific papers, unpublished reports, plant fact sheets, existing trait databases, regional floras, and plant guides.
This link launches the Grand Canyon Monitoring and Research Center’s discharge, sediment and water quality monitoring application gateway. Sediment and water quality information can be accessed from here for our on-going monitoring taking place across the Southwest U.S.
Several applications related to the Grand Canyon Monitoring and Research Center’s long-term sandbar monitoring project can be accessed here, including the sandbar area and volume tool and applications highlighting changes to sandbars as a result of High-Flow Events (HFEs) conducted by Glen Canyon Dam near Page, Arizona.
This story map application provides an interactive map showing light trap locations along the Colorado River as well as other content further describing this Citizen Science initiative. Data are currently available for the years 2012 through 2014, with more recent efforts coming soon.
This application allows for the exploration of a select set of insect emergence data collected as part of a citizen science project initiated by the Grand Canyon Monitoring and Research Center (GCMRC). Data present in this application relate to a recent BioScience publication from USGS scientists and collaborators that investigated the effects of dam operations on downstream aquatic insects.
Data were compiled based on field observations and available literature. Field data were collected on sandbars along the Colorado River through Grand Canyon between river miles 0 and 226 and included plant cover and trait measurements. Plant height and photosynthetic pathway were gleaned from the literature. Trait values were converted to a community-level value.
These data are compiled from published studies of various subspecies of the slider turtle (Trachemys scripta) from throughout the native range of the species in the United States. Data include sample sizes of adult male and female turtles as well as various estimates of their body size.
