Airborne electromagnetic (AEM) and magnetic survey data were collected by CGG Canada Services Ltd. in collaboration with the US Geological Survey (USGS) for the City of Cedar Rapids in a 53-square-kilometer area of the Cedar River Basin 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.
