This data product is extremely data intensive. Processing this data takes time. Data products are pre-processed for quick retrieval. However, the pre-processing may not be up to date, in that case, data products will be generated on-the-fly, which can take 5-20 minutes per 3 hour file.

The plot for the IMAGING mode shows the isosurfaces of the gridded data in the MAT file. Red, purple and blue isosurfaces are constant backscatter intensity surfaces at 65, 75, and 85 dB. Green-to-yellow surface is the bathymetry from the MBARI-UW 2008 multi-beam survey; black lines are contours of elevation. All distances are in meters relative to the sonar position. Tick labeling on the axes was left off due to technical difficulties in rendering the fonts (we could either render the 3D transparency or the fonts but not both, this is a short coming of running Matlab in Linux, which may improve in the future).

Example:
The PDF plot shown is the same as the PNG, however, PDF files can contain multiple plots in a vectorized form, which is better for high resolution printing or zooming.
