Data and Tools

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.

Geologic Map of North America

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.

Global Ecosystems

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.

Regional Research Web Cameras

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.

USGS/NOAA North American Packrat Midden Database

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.

Development of a Multimetric Index for Integrated Assessment of Salt Marsh Ecosystem Condition

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.

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.

DATA RELEASE - Bioelectrical Impedance Analysis for an Endangered Desert Fish

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.

DATA RELEASE - Desert Tortoise Reproductive Ecology and Precipitation, Mojave and Sonoran Deserts

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.
