Airborne electromagnetic and magnetic survey data in Big Cypress National Preserve, Florida, 2001

Airborne electromagnetic (AEM) and magnetic survey data were collected in Big Cypress National Preserve, Florida as part of a larger survey. Data were collected during October 2001. The Big Cypress National Preserve part was the largest of three segments, totaling 2692.2 line-kilometers. Electromagnetic data were acquired with Dighem VRES frequency-domain system. Magnetic data were collected with a Scintrex CS2 cesium-vapor magnetometer. The line spacing was 400 m and several tie lines were flown. The nominal elevation of electromagnetic system was 30 m. This data release includes raw and processed AEM data.
This release also includes unprocessed and processed magnetic data that have been drift corrected.
