This geologic map is a product of a cooperative project between the U.S. Geological Survey and the U.S. National Park Service to provide geologic information about this part of Canyonlands National Park, Utah. This digital map database contains bedrock data from previously published data that has been modified by the author. New mapping of the surficial deposits represents the general distribution of surficial deposits of the Druid Arch and The Loop 7.5-minute quadrangles.
Probabilistic seismic hazard maps were prepared for Alaska portraying peak horizontal ground acceleration and horizontal spectral response acceleration for 0.2, 0.3, and 1.0 second periods with probabilities of exceedance of 10% in 50 years and 2% in 50 years. This particular data set is for peak horizontal acceleration with a 10% probability of exceedance in 50 years. All of the maps were prepared by combining hazard derived from spatially-smoothed historic seismicity with hazard from fault-specific sources. The acceleration values contoured are the random horizontal component. The reference site condition is firm rock, defined as having an average shear-wave velocity of 760 m/sec in the top 30 meters corresponding...

Geochemical data for soils collected in the United States and analyzed by the USGS. The data were originally entered into the in-house PLUTO database.
Spatial digital database for the geologic map of the east part of the Pullman 1°x2° quadrangle, Idaho
The paper geologic map of the east part of the Pullman 1 x 2 -degree quadrangle, Idaho (Rember and Bennett, 1979) was scanned and initially attributed by Optronics Speciality Corp. Inc. (Northride, CA) and remitted to the U.S. Geological Survey for furter attribution and publication of the geospatial digital files. The resulting digital geologic map GIS can be queried in many ways to produce a variety of geological maps.
A website with links to the Landscape Conservation Cooperative (LCC) Integrated Data Management Network (IDMN) final report as well as individual LCC websites. The IDMN worked with over 20 organizations over two years to bring coherence to the LCC information management landscape. Specifically, the IDMN Network tried to address ways LCC partners implemented the basic building blocks of data management. Issues addressed included building and sharing science products with partners, securely storing those data for the long term, and evaluating ways to get those outputs to cooperators and eventually the public. Over the course of the IDMN project, the scope was expanded to address ways to track projects that produced...
The sagebrush ecosystem is the largest ecosystem type in the continental U.S., providing habitat for more than 350 associated fish and wildlife species. In recognition of the need to conserve a healthy sagebrush ecosystem to provide for the long-term conservation of its inhabitants, the US Fish and Wildlife Service (Service) and United States Geological Survey (USGS) developed the Conservation Efforts Database version 2.0.0 (CED). The purpose of the CED is to efficiently capture the unprecedented level of conservation plans and actions being implemented throughout the sagebrush ecosystem and designed to capture actions not only for its most famous resident, the greater sage-grouse (Centrocercus urophasianus; hereafter,...

Local Ecological Knowledge and Climate Change Portal housing all of the data and products produced from this project.
The aim of this USGS program is to provide site specific sea-level rise predictions to land managers through the intensive collection of field data and innovative predictive modeling. In 2009 and 2010, thousands of elevation and vegetation survey points were collected in salt marsh at 12 sites surrounding San Francisco Bay. The elevation data was synthesized into a continuous elevation model for each site, providing land owners valuable baseline data. This site hosts the project report, pages describing each of the 12 marshes visited in this study, and maps and GIS data for all of the marshes including high-resolution digital elevation models.
This map describes the possible hazard from earthquake-induced landslides for the city of Berkeley, CA. The hazard depicted by this map was modeled for a scenario corresponding to an M=7.1 earthquake on the Hayward, CA fault. This scenario magnitude is associated with complete rupture of the northern and southern segments of the Hayward fault, an event that has an estimated return period of about 500 years. The modeled hazard also corresponds to completely saturated ground-water conditions resulting from an extreme storm event or series of storm events. This combination of earthquake and ground-water scenarios represents a particularly severe state of hazard for earthquake- induced landslides. For dry ground-water...

1995 National Oil and Gas Assessment Continuous-Type Plays within the Louisiana-Mississippi Salt Basins Province
The fundamental geologic unit used in the 1995 National Oil and Gas Assessment was the play, which is defined as a set of known or postulated oil and or gas accumulations sharing similar geologic, geographic, and temporal properties, such as source rock, migration pathways, timing, trapping mechanism, and hydrocarbon type. The geographic limit of each play was defined and mapped by the geologist responsible for each province. The play boundaries were defined geologically as the limits of the geologic elements that define the play, such as the limits of the reservoir rock, geologic structures, source rock, and seal lithologies. The only exceptions to this are plays that border the Federal-State water boundary. In...
Cell maps for each oil and gas play were created by the USGS as a method for illustrating the degree of exploration, type of production, and distribution of production in a play or province. Each cell represents a quarter-mile square of the land surface, and the cells are coded to represent whether the wells included within the cell are predominantly oil-producing, gas-producing, both oil and gas-producing, or dry. The well information was initially retrieved from the Petroleum Information (PI) Well History Control System (WHCS), which is a proprietary, commercial database containing information for most oil and gas wells in the U.S. Cells were developed as a graphic solution to overcome the problem of displaying...
SWWA26_750UTM is a digital bathymetric surface grid of the seafloor off the coast of Southwest Washington and Northwest Oregon. Grid cell spacing is 750m and the projection is UTM Zone 10. The surface was produced by gridding National Ocean Service (NOS) Hydrographic Surveys collected between 1926 and 1928. This work includes the most recent bathymetric data available on a regional scale over the inner to middle continental shelf off the coast of Washington. The results represent the best available estimate of the seafloor morphology for the time period circa 1926.
Geologic data sets for weights-of-evidence analysis in northeast Washington--1. Geologic raster data
This dataset contains the combination of geology data (geologic units, faults, folds, and dikes) from 6 1;100,000 scale digital coverages in eastern Washington (Chewelah, Colville, Omak, Oroville, Nespelem, Republic). The data was converted to an Arc grid in ArcView using the Spatial Analyst extension.
Preliminary Lithogeochemical Map Showing Near-Surface Rock Types in the Chesapeake Bay Watershed, Virginia and Maryland
This preliminary experimental lithogeochemical map shows the distribution of rock types in the Virginia and Maryland parts of the Chesapeake Bay watershed. The map was produced digitally by classifying geologic-map units according to composition, mineralogy, and texture; rather than by age and stratigraphic relationships as shown on traditional geologic maps. This map differs from most lithologic maps in that the lithogeochemical unit classification distinguishes those rock units having key water-reactive minerals that may induce acid neutralization, or reduction, of hosted water at the weathering interface. The validity of these rock units, however, is independent of water chemistry, because the rock units are...
