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 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 lithology.
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.
Projected Future Climate, Bioclimate, and Biome Changes for the Northwest United States and Southwest Canada
Climate and Bioclimate Figures
This dataset is comprised of eight files related to salt marsh monitoring data or measures of of human disturbance (i.e. human impacts in terms of physical, chemical, and land-use stressors) collected at 33 marsh study units (MSUs) in five National Parks within the NPS Northeast Coastal and Barrier Network (NCBN) along the NE coast of the US.
Analysis of Land Disturbance and Pygmy Rabbit Occupancy Values Associated With Oil and Gas Extraction in Southwestern Wyoming, 2012
Germaine, S.S., Carter, S.K., Ignizio, D.A., and Freeman, A.T., 2017, Analysis of Land Disturbance and Pygmy Rabbit Occupancy Values Associated With Oil and Gas Extraction in Southwestern Wyoming, 2012: U.S. Geological Survey data release, https://doi.org/10.5066/F7BR8QDD. DOI: 10.5066/F7BR8QDD
Life history attributes data for Arizona Grasshopper Sparrow (Ammodramus savannarum ammolegus) in Arizona 2013
The Arizona Grasshopper Sparrow (Ammodramus savannarum ammolegus) occurs in the desert and plains grasslands of southeastern Arizona, southwestern New Mexico, and northern Sonora, Mexico. This data was produced as part of the first intensive study of its life history and breeding ecology, providing baseline data and facilitating comparisons with other North American Grasshopper Sparrow subspecies.
These data were used to examine the effectiveness of a non-lethal tool (Bioelectrical Impedance Analysis) to estimate the physiological condition of endangered and threatened fishes in the Colorado River Basin. Humpback chub, bonytail, and roundtail Chub were subjected to different feeding trials to elicit a response in physiological condition.
Standardization and Application of an Index of Community Integrity for Waterbirds in the Chesapeake Bay
This data set is comprised of five files related to the modification and scoring of Index of Waterbird Community Integrity (IWCI) scores for all waterbirds of the Chesapeake Bay. One Excel file (A) contains a list of 100+ Chesapeake waterbird species and their species attribute and IWCI scores.
Data from Wilson, T.S., Sleeter, B.M., Sleeter, R. R., Soulard, C.E. 2014, Land use threats and protected areas: a scenario-based landscape level approach, Land, 3 (2): 362-389. Three maps showing land-use conversion potential, forest harvest potential, and conversion threat index are available for the Pacific Northwest, years 2000-2100.
Estimated precipitation data were compiled from 1995-2013 for sites near Palm Springs, CA and at Sugarloaf Mountain in the Tonto National Forest of AZ. We were interested in data for winter (October-March) and summer precipitation (June-September). These two periods are important for desert tortoise ecology since they trigger germination of food plants in the spring and in the summer.
