Data and Tools
Biology and Ecosystems Datasets
Mapping, Remote Sensing, and Geospatial Data
The data collected and the techniques used by USGS scientists should conform to or reference national and international standards and protocols if they exist and when they are relevant and appropriate. For datasets of a given type, and if national or international metadata standards exist, the data are indexed with metadata that facilitates access and integration.
Landscape intactness has been defined as a quantifiable estimate of naturalness measured on a gradient of anthropogenic influence. We developed a multiscale index of landscape intactness for the Bureau of Land Management’s (BLM) landscape approach, which requires multiple scales of information to quantify the cumulative effects of land use.
Periodical publications that provide statistical data on production, distribution, stocks, and consumption of significant mineral commodities. Information on minerals-related issues, including minerals conservation, sustainability, availability, materials flow, and the economic health of the U.S. minerals industry is also available.
Access maps of watershed nutrient contributions to the Nation's Estuaries and Great Lakes
View the geographic distribution of estimated use of numerous pesticides on agricultural land in the conterminous United States. A graph accompanies each map, which shows annual national use by major crop for the mapped pesticide for each year during the period.
An online graphical data tool provides annual summaries of nutrient and sediment concentrations and loads and streamflow information for 106 sites monitored as part of the USGS National Water-Quality Network for Streams and Rivers.
Data in support of manuscript "Evaluation of chemical control for invasive crayfish at a warmwater fish production hatchery"
Acute static toxicity tests to determine potency, dose-response, and selectivity of pesticides to White River Crayfish, Virile Crayfish, and Fathead Minnow. Data included are: Collection location and size of test organisms; Test chemical concentrations and recovery; Mortality and effect-based responses of test organisms; Water quality of test solutions.
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.
Data were compiled from field drift collections and from a meta-analysis of published drift literature. Field data were collected in 2014 from the Colorado River downstream of Glen Canyon Dam, Arizona. Data represent flow meter measurements taken at the mouth and adjacent to a drift net, and suspended solids concentrations collected by the drift net, over varying net deployment durations.
This dataset contains information from visual encounter surveys conducted between 2012 and 2016 by USGS as part of an ongoing Oregon spotted frog (Rana pretiosa) monitoring effort in the Oregon Cascade Mountain Range. We surveyed 91 sites using a rotating frame design in the Klamath and Deschutes Basins, Oregon, which encompass most of the species' core extant range.
This data release includes the data from simulations used to illustrate the behavior of inbreeding rate estimators and Python source code ("analytical expressions", "computer simulations", and "empricial data set") that can be used to analyze these data.
These plant and soil data were collected by Timothy M. Wertin and Sasha C. Reed in the spring, summer, and fall of 2011 at a climate manipulation experiment site near Moab, UT (38.521411, -109.470567). These data were collected to assess how warming affects leaf photosynthesis, soil CO2 efflux, and soil chemistry in plots of ambient and warming treatments.
