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.

National Assessment of Oil and Gas - Cotton Valley Group and Travis Peak-Hosston Formation Assessment Units, Western Gulf and East Texas Basin and Louisiana-Mississippi Salt Basins Provinces (047, 048 and 049)

The Assessment Unit is the fundamental unit used in the National Assessment Project for the assessment of undiscovered oil and gas resources. The Assessment Unit is defined within the context of the higher-level Total Petroleum System. The Assessment Unit is shown here as a geographic boundary interpreted, defined, and mapped by the geologist responsible for the province and incorporates a...

Quaternary Fault and Fold Database of the United States

The Quaternary Fault and Fold Database contains the results of thousands of scientific assessments of faults and associated folds in the United States that demonstrate geologic evidence for coseismic surface deformation in the Quaternary (the past 1,600,000 years). The Quaternary Fault and Fold Database includes information on the age of the most recent coseismic surface deformation, relative...

North Santiam River Temperature Model

USGS personnel constructed, calibrated, and tested a model of flow and water temperature in the North Santiam and Santiam Rivers, Oregon. These rivers are major tributaries to the Willamette River, and have been listed as impaired by the Oregon Department of Environmental Quality (ODEQ) due to water temperatures that exceed the Oregon State water-quality standard.

Willamette River Tributary Width Surveys

Measurements of the surface width of the Willamette River's largest tributaries were included in this project in order to provide an important check on the water-temperature models being constructed as the foundation for the Willamette temperature Total Maximum Daily Loads (TMDLs).

U.S. Seismic Hazard Maps - 2002 Edition

The 2002 U.S. Geological Survey (USGS) National Seismic Hazard Maps display earthquake ground motions for various probability levels across the United States and are applied in seismic provisions of building codes, insurance rate structures, risk assessments, and other public policy. This update of the maps incorporates new findings on earthquake ground shaking, faults, seismicity%2

High-Latitude Climate Transects

This completed project makes available datasets related to the High-Latitude Climate-Feedback Transects. These datasets cover a wide range of scales, from the entire Arctic circumpolar area, to several regional transects (Alaska, Eastern and Central Siberia), to very detailed ground data for a number of specific study sites.

EPA 40km Hexagons for Conterminous United States

This dataset of 40 square kilometer (sq. km) hexagons was created by the U.S. EPA's Environmental Monitoring and Assessment Program (EMAP) and is being released by the U.S. Geological Survey for public use. The 40 sq. km hexagons were derived from a grid consisting of a triangular array of points that cover the United States and neighboring Canada and Mexico. The base grid of points ha
