Sub-Bottom Profiling, June 16-17, 1998

In an effort to help determine the extent and condition of the blockade runner's iron hull buried in the mud, Denbigh Project Principal Investigator Arnold arranged for a sub-bottom sonar profile to be conducted at the wreck site.  The actual survey was done by Roger Caron of EdgeTech and Alan Craig of Survey Equipment Services, both of Houston.  EdgeTech and Survey Equipment Services provided all equipment used during the work.  A survey vessel was provided at a concessional price by Capt. Scott Hickman of Circle H Outfitters, Houston.  The team was also accompanied by Gary Martin of the INA Foundation.

The sub-bottom profiling sonar, known as a "chirp" sonar for the high-pitched clicking sound of its transmitter, penetrated the mud to a depth of about two meters, and recorded indications of buried ship remains.  Full analysis of the data is pending.
