NOTE: The different multibeam sonar systems used for each survey operate at different frequencies resulting in different backscatter intensities, depth of penetration, etc. While pixel values are relative to other values within a survey, pixel values are not relative between surveys. While the backscatter imagery on this page show the backscatter data from all surveys merged together, the backscatter data are published separately for each survey.

To download the multibeam bathymetry and acoustic backscatter data in XYZ ASCII and ArcInfo GRID formats, see DATA.
