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.
The sidescan-sonar data were collected and processed during USGS field activity 2000-005-FA to map the surficial geology of the Madison Swanson and Steamboat Lumps Marine Protected Areas. In particular, this dataset covers the transit between the two marine protected areas.

These are GeoTIFF images and associated world files of the data originally collected on field activity 2000-005-FA, recorded by ISIS acquisition system and processed while at sea. All files were acquired with 12 dB of gain.
This series of images represents all of the processed backscatter data collected on the transit from the Madison Swanson Marine Projected are to the Steamboat Lumps Marine Protected Area during USGS field activity 2000-005-FA and includes lines L52F1 to L52F5. L53F1 was not included because of poor data quality due to bad weather conditions.
Differential GPS, with an Ashtech BR2G beacon receiver, was used to navigate the ship. The towfish navigation system was a Benthos DS 7000 acoustic deck set that used range to towfish to account for layback of the towfish. The position of the towfish was corrected using HYPACK and ISIS software. The range to fish did not always work well. The assumed approximate horizontal offset is 20-30 meters.
The SIS 1000 towfish by Datasonics was used to collect all of the sidescan-sonar data at a 400 meter total swath width. The data were recorded using ISIS by Triton Elics International in QMIPS format.

XSonar processing software (Danforth and others, 1991) was used to process the sidescan sonar QMIPS files. The files were demultiplexed using a 4x3 sample interval and a normalization value of 8192. The scan size was 768 pixels, and the output resolution was 0.781250 meters. A command-line script was used to help remove surface noise. An example of the command line is: removeSurface -S20 -p10 -s10 -N10 -O0.6 -i l35f1. -o l35f1new. Manual bottom tracking was used in order to remove the water column from the swaths with the slant range correction. Destriping and beam angle corrections were applied using 300 lines with a 100 ping overlap; maximum beam angle of 90; response angle = 55; data normalization = 0; port/starboard tone adjust = ON. This processing effectively aids in suppressing speckle noise and reducing file size, and corrects for slant-range distortion, signal attenuation, and dropped sonar pings. This process step and all subsequent process steps were performed by VeeAnn A. Cross.

The individual lines were then processed with the WHIPS software package to additionally filter the lines using a 7 line filter. Since these are transit lines, there was no need to map odd and even lines into separate georeferenced images. However, the lines were mapped for additional work in PCI software (Paskevich 1992; Paskevich 1996). These images had a pixel resolution of 4 meters/pixel.

The final image was then exported from PCI as a TIFF image with an associated world file for georeferencing purposes. GeoTiffExamine was then used to add the world file information to the TIFF image transforming it into a GeoTIFF.

The online links to the data were updated to reflect the new server hosting the data. Additionally, other small edits could be made to the metadata, such as modifying http to https where appropriate. The metadata date (but not the metadata creator) was edited to reflect the date of these changes.

The pixel value (1-255) indicates the reflectance of the sea-floor surface. Light areas (high value) contain highly reflective substrate types, while fine-grained sediment produces a low reflectance and is found in dark areas (low value). A value of zero represents no data.
