> We have found more than 2000 amphorae which once bore wine, olive oil, or other classical trade items. Who knows what kinds of tools or utensils well find down there that will give us new understanding and answer many questions about ancient civilizations.
> In the spring of 1999, Nauticos searched for and found a missing Israeli submarine that disappeared 31 years ago. Its sonar equipment detected several mysterious objects some 10,000 feet below the surface. A state-of-the-art remotely operated vehicle revealed shipwrecks of tremendous historical and archeological significance. Detailed video and sonar imagery of one of the sites was sent to the Institute of Nautical Archeology at Texas A&M University. The shape of several amphorae large, oval two-handled vases used for storage confirmed the vessel dates back to the end of the third century, BC. At 10,000 feet, this makes it the deepest ancient shipwreck ever found. Another striking find is a cauldron that has been collecting sediment for more than 2000 years. A core sample of this sediment could hold secrets about changes in the Mediterranean Sea over the last two millennia.
