Airborne electromagnetic and magnetic survey data and inverted resistivity models, Cedar Rapids, Iowa, May 2017

Airborne electromagnetic (AEM) and magnetic survey data were collected in collaboration with the Iowa Water Science Center for the City of Cedar Rapids to the west of Cedar Rapids, Iowa. The survey was flown between May 4 and May 5, 2017 along 347 line kilometers. Electromagnetic data were acquired using RESOLVE frequency-domain helicopter-borne electromagnetic system. Magnetic data were collected with 1-Scintres Cesium Vapour (CS-3) magnetometer. Sensor elevation above ground was measured with Optech G-150 laser. The nominal elevation of the sensor was 30 m. This data release includes processed AEM and magnetic data and inverted resistivity depth sections.
