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...

Discover and access data, information, and decision tools related to our ocean, coasts, and Great Lakes. The National Ocean Council provides this site to support regional marine planning efforts across the country and to create a convenient place for anyone to find out more about our marine, coastal, and Great Lakes environments.

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,...

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...

** September 16, 2014: Because this information has immediate and time-sensitive relevance to public health and welfare owing to the Governor of California's declared drought emergency, it is being released as preliminary information. As preliminary information, it had been reviewed and approved to meet the needs for timely best science, but the methodology is subject to refinement. The information is provided on the condition that neither the U.S. Geological Survey nor the U.S. Government may...
