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

    Metadata Updated: October 28, 2023

    Airborne electromagnetic (AEM) and magnetic survey data, a total of 3065 line-kilometers, were collected during October 2001 in two survey blocks and four repeated lines from an earlier survey. The largest area, Block 1 totaling 2692.2 line-kilometers was flown over Big Cypress Preserve, smaller Block 2 along 277.1 line-kilometers was flown near the town of Homestead, and four lines totaling 95.2 line-kilometers were flown over Everglades National Park. The lines over Everglades National Park repeated the path of four lines from an earlier AEM survey collected in December 1994 (released under USGS Open-File Report 02-101 downloadable at https://pubs.er.usgs.gov/publication/ofr02101). 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 includes unprocessed and processed magnetic data that have been drift corrected.
