Dr. Robert Ballard, retired Naval Commander and deep-sea archeologist, greets V.I.P. guests for a photo Tuesday, Jan. 8, 2012 at the Ritz-Carlton Golf Resort in Naples, Fla. The explorer is most notable for his discovery of the RMS Titanic. He spoke during the Naples Town Hall Distinguished Speakers Series for 20 minutes during a V.I.P. session and then to the general admission attendees for about an hour. His most recent work is an investigation on proof of the flooding of the earth dating back to the biblical Noah.
