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.
View annual deposition maps of H+, sulfate, nitrate, ammonium, and total inorganice nitrogen across the Nation beginning in 1985.
Discover over 17,000 fish, macroinvertebrate, and algal samples and physical habitat data collected at over 2,000 sites by the USGS since 1991.
Identify, access, and interpret USGS discrete and (or) daily suspended sediment data suspended-sediment and related data. The U.S. Geological Survey National Water Information System (NWIS) is the original source for all suspended-sediment data provided in the portal.
The Water Quality Portal (WQP) is a cooperative service sponsored by the United States Geological Survey (USGS), the Environmental Protection Agency (EPA), and the National Water Quality Monitoring Council (NWQMC). It serves data collected by over 400 state, federal, tribal, and local agencies.
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 Data for the matrix were compiled from published scientific papers, unpublished reports, plant fact sheets, existing trait databases, regional floras, and plant guides.
The USGS Core Library and Data Center is located inside the Nevada National Security Site (NNSS, formerly Nevada Test Site (NTS)) at Mercury, Nevada. The Core Library was established as a repository for geologic, hydrologic, and geophysical data and materials collected in support of the U.S. Department of Energy defense and environment programs at the NNSS.
Water-level data used for the maps of water-level changes in the High Plains aquifer for the eight states that overly the aquifer are available. The data files are tab-delimited and provided as zip files. Data are available by year for predevelopment, 1980, and 1995-2013.
Catchment-flowline network and selected model inputs for an enhanced and updated spatially referenced statistical assessment of dissolved-solids load sources and transport in streams of the Upper Colorado River Basin
This USGS data release consists of the synthetic stream network and associated catchments used to develop spatially referenced regressions on watershed attributes (SPARROW) model of dissolved-solids sources and transport in the Upper Colorado River Basin as well as geology and selected Basin Characterization Model (BCM) data used as input to the model.
Microsomal EROD data of fish liver sample assay from species collected in the Salt and Gila Rivers, Arizona
This dataset includes microsomal EROD data from an assay done with liver samples from several fish species that are found in Arizona at sites that are being assessed for PBDE contamination. The data was created in September and October 2016.
Use the mapping tool to predict concentrations for 108 pesticides in streams and rivers across the Nation and identify which streams are most likely to exceed water-quality guidelines for human health or aquatic life.
To create this dataset the authors exposed larval mayflies (Baetis tricaudatus) to an aqueous zinc gradient (3-340 µg Zn/l) and measured the change in zinc tissue concentrations at different stages of metamorphosis and changes in stable isotopes (δ15N and δ13C) in unexposed B. tricaudatus. Zinc concentrations in larvae and adults were positively related to aqueous concentrations.
This website presents population change information for more than 400 species of North American birds, as estimated from the North American Breeding Bird Survey. Estimates of trend (interval-specific estimates of population change), annual indices of abundance, and maps of abundance and population change for these species are presented for a variety of regions.
