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.
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
Bioclimatic variables for the northwest United States and southwest Canada in netCDF files.
Statistically-downscaled monthly historical (1901-2000) CRU TS 2.1 and projected future (2001-2099) CMIP3 A2 and A1B simulated temperature, precipitation, and sunshine data on a 30-second grid of the northwest United States and southwest Canada
Downscaled climate data for the northwest United States and southwest Canada in netCDF files.
This dataset includes two spreadsheets: The "Avian_abundance_oak_mistletoe_bird_data" spreadsheet contains data regarding Oregon White Oak tree (Quercus garryana) measurements. The "Avian_abundance_oak_mistletoe_surveys_data" spreadsheet contains bird survey observations.
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.
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...
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.
The Geologic Map of North America portrays the grand architecture of the continent as we understood it in the closing years of the 20th century (The Geological Society of America, Inc., 2005). It is the final product of the Geological Society of America's Decade of North American Geology project, and covers about 15% of the Earth's surface at a scale of 1:5,000,000.
Data from the Global Ecosystems activity allow for a fine resolution inventory of land-based ecological features anywhere on Earth, and contribute to increased understanding of ecological pattern and ecosystem distributions. Ongoing efforts focus on an ecological land classification approach emphasizing ecologically meaningful characteristics of the land, i.e. bioclimate, landform, and...
Access to regional web cameras located in the desert southwest and arctic Alaska. Desert cameras capture and document regional climate variability with a specific focus on local and regional dust emission and transport. The artic Alaska cameras capture and document regional climate variability with a specific focus on snow cover and permafrost feature evolution.
The USGS/NOAA North American Packrat Midden Database makes thousands of identified specimens and hundreds of published reports available in a standardized, quality-controlled format. This version offers the most comprehensive, high-quality archive of midden data available for North America, and facilitates Quaternary paleoenvironmental studies on a range of local to regional scales.
