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. Purpose: The sidescan-sonar data were collected and processed during USGS field activity 2000-005-FA to map the surficial geology of the Madison Swanson Marine Protected Area.

All files in this mosaic were acquired with a 400 meter swath width (200 meter range). Lines L1F1 and the first part of L2F1 were acquired with no gain. All the rest of the files had 12 dB of gain. Completeness_Report: This mosaic represents all of the processed backscatter data collected in the Madison Swanson Marine Protected Area during USGS field activity 2000-005-FA. The line numbers falling in this particular area are L1F1 to L51F1. The following lines were not processed and incorporated into the mosaic because they represent turns: L6F2, L7F2, L9F2, L15F2, L19F2, L25F2. In general, the F2 files are turns, but in many cases at least portions of the files were necessary for a complete mosaic. Other lines not incpororated: L24F2 - test file using a 200 meter swath. The turns are not included in the mosaic. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: 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. Lineage: Process_Step: Process_Description: 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.

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.

These images had a pixel resolution of 1 meter/pixel. > Paskevich, V. F. 1992. Digital Mapping of Sidescan Sonar Data with the Woods Hole Image Processing System Software.

Open-File Report 96-281, 73 pp. Process_Date: 2000 Process_Step: Process_Description: Non-overlapping swaths were then brought into the remote sensing software package PCI Geomatics. Two channels were used so that one channel (line by line) could be brought in and mapped - mosaicked - to the other channel by picking control points to further constrain the positioning of the line. The lines set as "true" were the odd lines, and the even lines were mapped to those using control points. The final mosaic 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.

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.
