Title:
2006 Multibeam Mapping of cross-shelf corridor, North of Madison-Swanson - Florida
Abstract:
This disk or set of disks contain high-resolution multibeam and backscatter maps of an area North of Madison-Swanson (29.1667N, 85.6667W), in the West-Florida shelf, not included in a previous mapping expedition to the area. It includes the following products: 1) ESRI .ASC files, 2) Text file containing X, Y, Z postprocessed bathymetry data, 3) Geotiff and JPEG images from of bathymetry, 4) GeoTiff and JPEG images of backscatter, and 5) Fledermaus files of the survey locations. All products are available contacting the distributor. Some data sets are also posted on NOAA's Coral Reef Information System (CoRIS) at www.coris.noaa.gov. Another product that will not be distributed, but will be used as input to habitat classification software (QTC MultiView), are raw data files logged to disk using the Simrad EM3000 multibeam system data acquisition software. These raw files contain packets of information (depth soundings, navigation, attitude, sound velocity profiles, UTC time) that the acquisition software logged sequentially in time. The raw data format is available from Kongsberg-Simrad. The multibeam system was provided by University of South Florida, College of Marine Science and the support vessel was the Florida Institute of Oceanography R/V Suncoaster.
Supplemental_Information:
The survey was supported by University of South Florida, College of Marine Science, in St. Petersburg, FL, (www.marine.usf.edu) using a Simrad EM 3000 multi-beam system. The survey was funded by NOAA Fisheries (www.sefsc.noaa.gov).

Note on Bounding Box: Survey area was irregular in shape, the entire area within the corners was not mapped

Why was the data set created?

The primary objective of this mapping expedition is to find the location of deep water reefs along the West Florida shelf, which represent important habitat for reef fish. The Gulf of Mexico Fisheries Management Council recognize the importance of this geological setting when they established the Madison-Swanson and Steamboat Lumps Marine Protected Areas (MPA) in 1999. Precisely georeferenced high-resolution mapping of bathymetry is a fundamental first step to study the area of the continetal shelf and the shelf-edge suspected to be critical habitats.


How was the data set created?

  1. From what previous works were the data drawn?

  2. How were the data generated, processed, and modified?

    Date: 28-Jul-2006 (process 1 of 1)
    The bathymetry data were collected along a continuous swath perpendicular to the direction of the ship using a Kongsberg Simrad EM3000 (300 kHz) multibeam sonar system. The data are cleaned of bad navigation and depth soundings. The depth soundings are gridded into a common grid. The gridded data are converted to an XYZ ASCII format file (Longitude, Latitude, Depth in Meters).
