Entrapment: Global Ecological and/or Local Demographic? Reflections Upon Reading the BMJ's Six Billion Day Special Issue
This project described production of an information foundation for fish habitat research consisting of a “mashup” of data from multiple USGS data systems that are fragmented among the former USGS Divisions. The proposal aimed to develop and test the semantic approach to data integration by focusing on the problem of fish habitat modeling. Effective prediction of the abundance of particular species at particular locations is a primary objective of both ecology and natural resource management. Better knowledge of aquatic fish ecology and habitat requirements and improved tools for assessment and planning are needed to help conserve and rehabilitate populations throughout their native range. Benefits Single access...
2012 Updates (from the FY12 Annual Review) The NWIS Web Services Snapshot represents the next generation of data retrieval and management. The newest Snapshot tool allows instant access to NWIS data from four different web services through ArcGIS, software available to all USGS scientists in all mission areas. Increased data retrieval efficiency reduces the steps required to retrieve and compile water data from multiple sites from what can be more than 30 steps to just a few clicks. As an end-user education tool, it promotes use of NWIS data from both web services and the NWIS database, which increases the production of scientific research and analysis that uses NWIS data. The Snapshot database design enables efficient...
Evaluation of Statistically Downscaled GCM Output as Input for Hydrological and Stream Temperature Simulation in the Apalachicola–Chattahoochee–Flint River Basin (1961–99)
Citation: Lauren E. Hay, Jacob LaFontaine, and Steven L. Markstrom, 2014: Evaluation of Statistically Downscaled GCM Output as Input for Hydrological and Stream Temperature Simulation in the Apalachicola–Chattahoochee–Flint River Basin (1961–99). Earth Interact., 18, 1–32. doi: http://dx.doi.org/10.1175/2013EI000554.1 Abstract: The accuracy of statistically downscaled general circulation model (GCM) simulations of daily surface climate for historical conditions (1961–99) and the implications when they are used to drive hydrologic and stream temperature models were assessed for the Apalachicola–Chattahoochee–Flint River basin (ACFB). The ACFB is a 50 000 km2 basin located in the southeastern United States. Three...
