Mississippi Alluvial Plain: Regional Geophysical Survey
In 2017, the USGS Mississippi Alluvial Plain (MAP) Regional Water Availability Study began an airborne geophysical mapping campaign to improve understanding of the geology and structure of the Mississippi River Valley alluvial aquifer. Two different airborne electromagnetic (AEM) platforms, the frequency-domain Resolve and time-domain Tempest, were flown by CGG Airborne. Regional surveys over the entire study area were acquired with both systems, providing multi-scale resolution of the aquifer system. In addition, a high-resolution inset grid was acquired near Shellmound, Mississippi.
