This web site describes the Pacific Coastal and Marine Science Center Project titled, "The Impact of Sea-Level Rise and Climate Change on Pacific Ocean Atolls that House Department of Defense Installations." The study itself is a collaboration between the U.S. Geological Survey (USGS), the National Oceanographic and Atmospheric Administration (NOAA), Deltares (an applied research institute in the Netherlands), and the University of Hawaii (UH). The goals of this study are to: 1.) provide basic understanding...

Gap Analysis Project (GAP) habitat maps are predictions of the spatial distribution of suitable environmental and land cover conditions within the United States for individual species. Mapped areas represent places where the environment is suitable for the species to occur (i.e. suitable to support one or more life history requirements for breeding, resting, or foraging), while areas not included in the map are those predicted to be unsuitable for the species. While the actual distributions...

This dataset combines the work of several different projects to create a seamless data set for the contiguous United States. Data from four regional Gap Analysis Projects and the LANDFIRE project were combined to make this dataset. In the northwestern United States (Idaho, Oregon, Montana, Washington and Wyoming) data in this map came from the Northwest Gap Analysis Project. In the southwestern United States (Colorado, Arizona, Nevada, New Mexico, and Utah) data used in this...

Researchers with the USGS Western Geographic Science Center and Eros Data Center have developed a semi-automated procedure to map the country's mining footprint and establish a baseline to monitor changes in mine extent over time. The process includes a tool that uses seed points sourced from the US Energy Information Administration (EIA), USGS Mineral Resources Data System (MRDS), and USGS National Land Cover Dataset (NLCD) and recodes patches of barren land that meet a 'distance...

Moving-boat surveys are used to produce water-quality maps at least six times per year. The boat surveys typically began at the boat ramp near Punta Rassa, enters San Carlos Bay, travel around Pine Island and finally travel upstream along the Caloosahatchee River, ending at the W. P. Franklin Lock and Dam (S-79). Sensor and coordinate data are recorded as the boat travels throughout the study area making measurements using a flow-through onboard pump system. Salinity,...

In situ recovery (ISR) uranium mining is a technique in which uranium is extracted by a series of injection and recovery wells developed in a permeable sandstone host rock. Chemical constituents (lixiviants) are added to groundwater injection wells to mobilize uranium into groundwater. Before mining, baseline water quality is measured by sampling groundwater from the aquifer intended to be mined and over and underlying units over a geographic area that reflects the proposed mine location....
