    • Georeferenced TIFF image displaying 1 meter resolution backscatter data collected by the U.S. Geological Survey in the Madison Swanson Marine Protected Area, Gulf of Mexico in 2000 (UTM Zone 16N, WGS 84, GeoTIFF image)

    Metadata Updated: January 16, 2026

    The U.S. Geological Survey (USGS) mapped approximately 22 square miles of the Madison Swanson Marine Protected Area (MPA) and Steamboat Lumps MPA, which are located on the Florida shelf edge in the northeastern Gulf of Mexico in 2000 using sidescan sonar and high-resolution chirp seismic-reflection systems. This survey was conducted as part of a larger study of the effectiveness of no-fishing reserves in protecting grouper spawning aggregations. Field activity information for this cruise is available on-line through the U.S. Geological Survey Coastal and Marine Geoscience Data System at https://cmgds.marine.usgs.gov/fan_info.php?fa=2000-005-FA.
