The IVS3D Fledermaus software suite was used to view the bathymetric surface in a three-dimensional representation (3D). The software suite enables the user to “fly through” the study area while presenting unique perspectives and improving data interpretation. The software also allows for the creation of flightpaths that can be used to make movie files. The flightpaths can be experienced with the free viewer (iView4D) for files in the Fledermaus format. Several Fledermaus scientific data (.sd) files and scene (.scene) files that were derived from the GIS grid layers have been included in this report and are listed below. These files may be used with iView4D to provide the experience of a "fly through" of the bathymetry surface.

How to Download iView4D:

• Go to the IVS Website
• Go to Download
• Click on iView4D
  Fill out form and download iView4D. The help menu in iView4D gives detailed operating instructions.
