Science Datasets
Science Datasets
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.
National Water Census Data Portal
The National Water Census Data Portal contains national estimates of water budget components for local watersheds, water withdrawal data for counties, tools to calculate statistics of daily streamflow records, modeled daily streamflow at ungaged stations, and access to records of aquatic biology observations.
2017 Known and Probable Grizzly Bear Mortalities in the Greater Yellowstone Ecosystem
Identifying the locations and causes of grizzly bear mortality is another key component in understanding the dynamics of this population. Over 80% of all documented bear mortalities are human-caused. Tracking human-caused bear deaths helps define patterns and trends that can direct management programs designed to reduce bear mortality.
DATA RELEASE - Water Classification of The Colorado River Corridor, Grand Canyon, Arizona, 2013—Data
These data are classified maps of water in the Colorado River at a discharge of approximately 227 meters squared/second in Grand Canyon from Glen Canyon Dam to Pearce Ferry in Arizona. The data are derived from interpretation of multispectral high resolution airborne imagery that was acquired in May 2013.
DATA RELEASE - Riparian Vegetation Classification of the Colorado River Corridor, Grand Canyon, Arizona, 2013—Data
These data are classification maps of total riparian vegetation along the Colorado River in Grand Canyon from Glen Canyon Dam to Pearce Ferry in Arizona, and are derived from interpretation of multispectral high resolution airborne imagery acquired in May 2013.
Atypical Feeding Behavior of Long-tailed Ducks in the Wake of a Commercial Fishing Boat while Clamming
Data represents analyses of gizzard and gullet (esophagus and proventriculus) of nine ducks using traditional techniques
DATA RELEASE - Southwest Exotic Mapping Program (SWEMP) Database, 2007
The Southwest Exotic Plant Mapping Program (SWEMP) is a collaborative effort to compile and distribute regional data on the occurrence of non-native invasive plants in the southwestern U.S. The database represents the known sites of non-native invasive plant infestations within AZ and NM, and adjacent portions of CA, CO, NV and UT. These data were collected from 1911to 2006.
LPJ biomes (30-year mean) simulated using monthly historical (1901-2000) CRU TS 2.1 climate data and projected future (2001-2099) CMIP3 A2 and A1B simulated climate data on a 30-second grid of the northwest United States and southwest Canada
LPJ simulated biomes for the northwest United States and southwest Canada in netCDF files.
Bioclimatic variables calculated from statistically-downscaled historical (1901-2000) CRU TS 2.1 climate data and projected future (2001-2099) CMIP3 A2 and A1B simulated climate data on a 30-second grid of the northwest United States and southwest Canada

Borehole Temperature Logs from Arctic Alaska, pre-1989
The Borehole Temperature Logs provide temperature measurements acquired in permafrost regions of arctic Alaska between 1950 and 1988 by the USGS at 87 sites deep enough to penetrate the base of permafrost.
Climate Impact Meteorological Stations (CLIM-MET) Data and Repeat Photography
Meteorological data and repeat photography captured at Climate Impact Meteorological (CLIM-MET) stations located in the Canyonlands National Park and Mojave National Preserve. Data from ecologically sensitive sites in the Southwest help determine the distribution and types of surficial deposits and the processes responsible for the deposits, and contribute to understanding vegetation distribution.
Dust Event Detection
A catalog of dust events in the southwestern United States since 2009. Dust emission from sources in the southwestern United States is important on local and regional scales because of its effects on air quality, human health and safety, snow melt timing and water management, and on ecosystem function through the depletion and (or) addition of soil nutrients.
