From the article:
ARLES, France — In a dark space in a new exhibition at Arles museum in southern France, underwater sounds play over looped video footage of scientists on underwater digs along the Rhone riverbed.
An intrepid team of archaeologists have been diving for 20 years, struggling with poor visibility, strong currents and flipper-nibbling bullhead catfish to bring up the 500 or so objects now being displayed.
In 2007, just when these Indiana Joneses of the water were ready to hang up their wet suits, they bumped into intriguing column fragments, friezes and chunks of mausoleums.
And then they brought up the most extraordinary buried treasure of all: a bust of Julius Caesar.
The find, dated 46 BC, is all the more remarkable for likely being made during the emperor's lifetime and provides the centrepiece for the exhibition organised by Luc Long, head of the French state department for archaeological, subaquatic and deepsea research.
