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

Airborne electromagnetic (AEM) and magnetic survey data, a total of 3065 line-kilometers, collected during October 2001 with line spacing 400m and nominal altitude of 30m. Includes raw and processed AEM data and magnetic data, in CSV format.

Info
Airborne electromagnetic data and processing within Leach Lake Basin, Fort Irwin, California

Releases airborne survey data, resistivity cross-sections and depth slices derived from data inversion. Resulting resistivity models confirm geologic framework, constrain hydrostratigraphy and depth to basement, and reveal fault and fold distribution.
