Results 121 - 130 of 155 listed by similarity [list alphabetically]
Trumpeter swan [More info]
Studies of the trends of the Rocky Mountain population of trumpeter swans using time series analysis.
PDF U.S. Geological Survey methodology development for ecological carbon assessment and monitoring [More info]
To assess the effectiveness of ecological carbon sequestration, we plan to define ecosystem reporting units, model baseline and potential carbon sequestration, develop spatial models that simulate ecosystems, and integrate remote sensing data.
PDF UCERF3: A new earthquake forecast for California's complex fault system [More info]
Explains how we estimate the probability of earthquakes in the state of California. The underlying scientific model was improved to account for factors that can affect the severity of earthquakes.
PDF Understanding beach health throughout the Great Lakes-Entering a new era of investigations [More info]
People who manage recreational areas need better, more timely estimates of the likelihood that the beach and lake waters will be hazardous to human health, and which factors cause those hazards.
PDF United States Geological Survey (USGS) natural hazards response [More info]
The primary goal of U.S. Geological Survey (USGS) Natural Hazards Response is to ensure that the disaster response community has access to timely, accurate, and relevant geospatial products, imagery, and services during and after an emergency event.
PDF Use of Light Detection and Ranging (LiDAR) to Obtain High-Resolution Elevation Data for Sussex County, Delaware [More info]
Methods and techniques used to collect and process LiDAR elevation data, the generation of the digital elevation model (DEM) and the 2-foot contours, and the quality-assurance procedures and results.
PDF Use of Minerals and Materials in the United States From 1900 Through 2006 [More info]
Types and quantities of raw materials used by U.S. manufacturers and consumers, which have changed significantly as the economy has moved from one that is predominantly agricultural to one that is primarily industrial.
USGS and the Southern California Integrated GPS Network (SCIGN) [More info]
Field Office involved in operating GPS stations, data recording, and supplying of earthquake data. Links to GPS data analysis, photos, and technical information.
USGS National Map of Surficial Mineralogy [More info]
Maps of exposed surface mineral groups derived from automated spectral analysis of satellite and airborne imaging systems; these data suggest areas that may contain mineral deposits of various types.
Using geochemical and statistical tools to identify irrigated areas that might contain high selenium concentrations in surface water [More info]
