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.
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.
Winter-spring streamflow volume and timing data for 75 Hydroclimatic Data Network-2009 basins in the conterminous United States 1920-2014
This dataset contains gage information for 75 Hydroclimatic Data Network-2009 basins in the conterminous United States and associated annual runoff volume, winter-spring runoff volume, and winter-spring runoff timing data 1920-2014, as well as trend results for WSCVD and WSV for periods 1920-2014, 1940-2014, and 1960-2014.
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.
Geochemistry of concentrates from the National Geochemical Database. Primarily inorganic elemental concentrations, most samples are from the continental US and Alaska.
Geochemistry of sediments from the National Geochemical Database. Primarily inorganic elemental concentrations, most samples are of stream sediment in the continental US and Alaska.
Geochemistry of soils from the National Geochemical Database. Primarily inorganic elemental concentrations, most samples are from the continental US and Alaska.
The USGS Geo Data Portal (GDP) project provides scientists and environmental resource managers access to downscaled climate projections and other data resources that are otherwise difficult to access and manipulate. This user interface demonstrates an example implementation of the GDP project web-service software and standards-based data integration strategy.
ScienceBase provides access to aggregated information derived from many data and information domains, including feeds from existing data systems, metadata catalogs, and scientists contributing new and original content.
These data provide the locational coordinates, soil texture characteristics, plant species occurrence and cover, and vegetation summary characteristics for the Tsezhin bii region in the south-central area of the Navajo Nation.
DATA RELEASE - Four Band Image Mosaic of the Colorado River Corridor in Arizona--2013, including Accuracy Assessment Data
The imagery data are airborne multispectral high resolution data for the Colorado River in Grand Canyon in Arizona, USA. The data consist of four bands (blue, green, red and near infrared) with a ground resolution of 20 centimeters (cm). These data are available to the public as 16-bit geotiff files.
