From the WaterWatch about information: WaterWatch (http://waterwatch.usgs.gov) is a U.S. Geological Survey (USGS) World Wide Web site that displays maps, graphs, and tables describing real-time, recent, and past streamflow conditions for the United States. The real-time information generally is updated on an hourly basis. WaterWatch provides streamgage-based maps that show the location of more than 3,000 long-term (30 years or more) USGS streamgages; use colors to represent streamflow conditions compared to historical streamflow; feature a point-and-click interface allowing users to retrieve graphs of stream stage (water elevation) and flow; and highlight locations where extreme hydrologic events, such as floods...

The Southeastern United States spans a broad range of physiographic settings and maintains exceptionally high levels of faunal diversity. Unfortunately, many of these ecosystems are increasingly under threat due to rapid human development, and management agencies are increasingly aware of the potential effects that climate change will have on these ecosystems. Natural resource managers and conservation planners can be effective at preserving ecosystems in the face of these stressors only if they can adapt current conservation efforts to increase the overall resilience of the system. Climate change, in particular, challenges many of the basic assumptions used by conservation planners and managers. Previous conservation...

The USGS and South Atlantic LCC worked with stakeholders and managers across the Southeast to identify and assess landscape-level strategies for conserving multiple species. These strategies incorporated predictions from downscaled climate models, sea level rise, and changes to aquatic and terrestrial habitats.

This raster depicts the percentage of lithological potassium oxide (K2O) content in surface or near surface geology. We derived these rasters by calculating the average percent K2O content for each map unit in combined surficial-bedrock geologic maps. We used state geologic maps (Preliminary Integrated Geologic Map Databases for the United States, Open File Reports 2004-1355, 2005-1305, 2005-1323, 2005-1324, 2005-1325, 2005-1351, and 2006-1272), which depict surficial geology instead of bedrock when the surficial layers are sufficiently deep. For the state maps that do not incorporate surficial geology (i.e., midwestern states), we overlaid surficial geologic map units with thicknesses greater than 100 feet (from...

This raster depicts the percentage of lithological ferric oxide (Fe2O3) content in surface or near surface geology. We derived these rasters by calculating the average percent Fe2O3 content for each map unit in combined surficial-bedrock geologic maps. We used state geologic maps (Preliminary Integrated Geologic Map Databases for the United States, Open File Reports 2004-1355, 2005-1305, 2005-1323, 2005-1324, 2005-1325, 2005-1351, and 2006-1272), which depict surficial geology instead of bedrock when the surficial layers are sufficiently deep.

An R package to interact with the BISON search API. BISON (Biodiversity Information Serving Our Nation) is a product of the U.S. Geological Survey's Core Science Analytics and Synthesis Program. BISON is an information system that allows users to access, explore, and download U.S. species occurrence data from participating data providers. http://bison.usgs.ornl.gov/

This map shows least-cost corridors and large natural habitat blocks. These blocks and corridors may provide an essential network for various species to disperse through the landscape. Blocks are based on large areas of contiguous natural vegetation cover, and are subdivided by major roads. We connected blocks using sticks (to define a pair of blocks between which to model corridors), and developed least-cost corridors based on a cost surface developed from land cover.

This map shows water-based recreation travel corridors (selected from NHD flowlines), and land-based recreation travel corridors (selected from BLM GTLF within federal / state lands and national trails).
