Airborne electromagnetic (AEM) survey data collected along the Mississippi River and tributaries

Airborne electromagnetic (AEM) survey data collected along the Mississippi River and tributaries used streambed resistivity to map the extent of groundwater connectivity from strong to weak (part a), and provided three-dimensional cross sections of the materials underlying the streams (parts b-f.  Figure from Minsely et al., 2021).
