Mercury source identification in the Mobile and Tombigbee Rivers Mercury source identification in the Mobile and Tombigbee Rivers
This dataset details mercury concentrations and mercury stable isotope values collected as part of an environmental mercury assessment encompassing the Mobile and Tombigbee Rivers as well as two U.S. Environmental Protection Agency Superfund sites. The Tensaw River was also sampled as part of this study as a reference site, absent of mercury contamination. As a part of this survey...
Regional screening for managed aquifer recharge suitability in Jordan, Lebanon, and surrounding areas Regional screening for managed aquifer recharge suitability in Jordan, Lebanon, and surrounding areas
The U.S. Geological Survey (USGS), in cooperation with the U.S. Agency for International Development, Arab Water Council, Hydrology.NL, National Center for Research and Development (Jordan), and American University of Beirut, completed a project for acceleration of aquifer storage and recovery in the Middle East and North Africa (MENA) region. The MENA region is globally the most water...
Density raster of caves in Monroe County, West Virginia Density raster of caves in Monroe County, West Virginia
Monroe County, in southeastern West Virginia, hosts world-class karst within carbonate units of Mississippian and Ordovician age. There are at least 412 known caves in the county. Location data for these caves were collected from the West Virginia Speleological Survey (WVASS) Bulletin 22 (Dasher, 2019). Point features were created in ArcGIS Pro for each cave location and were used to...
National Surface Water Maps using Daily MODIS Satellite Data for the Conterminous United States, 2003-2019 National Surface Water Maps using Daily MODIS Satellite Data for the Conterminous United States, 2003-2019
Members from the U.S. Geological Survey (USGS) Patterns in the Landscape - Analyses of Cause and Effect (PLACE) team are releasing monthly surface water maps for the conterminous United States (U.S.) from 2003 through 2019 as 250-meter resolution geoTIFF files. The maps were produced using the Dynamic Surface Water Extent (DSWE) algorithm applied to daily Moderate Resolution Imaging
Directory of Public Repositories of Geological Materials Directory of Public Repositories of Geological Materials
Overview This directory was developed to provide discovery information for anyone looking for publicly accessible repositories that house geological materials in the U.S. and Canada. In addition, this resource is intended to be a tool to facilitate a community of practice. The need for the directory was identified during planning for and follow-up from a drill core repository webinar...
Geospatial Data to Assess Karst Aquifer Systems Between Albany and Buffalo, New York (ver. 4.0, January 2024) Geospatial Data to Assess Karst Aquifer Systems Between Albany and Buffalo, New York (ver. 4.0, January 2024)
Publicly available geospatial data were identified, collated, and analyzed for a region of karst terrain extending from Albany to Buffalo, New York. A series of geospatial datasets were assembled to determine the location and extent of karstic rock; bedrock geology and depth to bedrock; average water-table configuration; surficial geology; soil type, thickness, and hydraulic conductivity...
