Mississippi Embayment Regional Aquifer Study (MERAS) interactive subsurface map

Subsurface data used in the interactive map is based on a geophysical log database and work produced in USGS Scientific Investigations Report 2008-5192 and Scientific Investigations Report 2008-5098 (see links below). The current geophysical log database is considered to be version 1.0. A version number may be helpful to track future updates to interpretation of hydrogeologic unit tops as more data are acquired and the overall understanding of the subsurface changes.
