Breathless Exploration: Dr. Robert D. Ballard and the Black Sea

Dr. Robert D. Ballard is arguably the most acclaimed undersea explorer of his generation, and the Black Sea is potentially the richest hunting ground for marine archaeologists on the planet, so it is little wonder that Ballard has been so obsessed with his work in the Black Sea. If his exploits in the Black Sea are successful, they could unlock secrets of human settlement, trade, and even mythology dating back 7,500 years.

Our story begins in around 5500 B.C., when the Black Sea was most likely an inland freshwater lake separated from the Mediterranean Sea by an earthen dam. Glacial melting at the end of the Quarternary Ice Age caused the Mediterranean to overflow its boundaries and, after centuries of pressure, finally overcome this dam, flooding the lake and quickly expanding it into the saltwater body we now call the Black Sea. Some scientists theorize that this event was the basis for the "Great Flood" myths found in many cultures, including the Judeo-Christian story of Noah, the Mesopotamian epic of Gilgamesh, and the Greek myth of Deucalion.

Beyond its mythical implications, however, the formation of the Black Sea created an environment ripe with archaeological allure. First, if the flooding that created the Black Sea occurred with anything approaching the speed depicted in flood legends, it almost certainly overran and possibly preserved ancient human settlements. Moreover, the unique origins of the Black Sea are the most likely explanation for the presence of an anoxic, or "oxygenless," layer near its bottom. This anoxic layer is almost completely lifeless, meaning it lacks the organisms that aid in the decomposition of wood and cloth, which might have sunk to the bottom of the Black Sea. In other words, ancient wooden shipwrecks can remain intact on the Black Sea's floor thanks in part to the anoxic layer.

Enter Dr. Robert D. Ballard, perhaps the most acclaimed shipwreck hunter in the world. Ballard's résumé reads like a Who's Who of famous shipwrecks, including the 1985-1986 discovery and exploration of the doomed luxury liner Titanic; the 1989 discovery of the notorious World War II German battleship Bismarck; the 1998 discovery of the American World War II aircraft carrier Yorktown, which was lost at the Battle of Midway; and the 2002 discovery of the U.S. Navy patrol ship PT 109, which was commanded by the future U.S. president John F. Kennedy and sank in 1943.

Ballard's Black Sea discoveries, however, have been far more ancient than these high-profile 20th-century finds. Since the late 1990s, Ballard has been following the unmistakable presence of discarded amphorae--ancient clay jars used to ferry cargo on sailing vessels--that litter the floor of the Black Sea. Sailors often tossed the amphorae overboard to lighten the load of sinking vessels, which in turn created "breadcrumb trails" leading directly to ancient shipwrecks.

Among Ballard's amphora-guided Black Sea finds are three ancient shipwrecks and a possible site of preflood human settlement. The settlement area, called Site 82, may appear to the untrained eye to be nothing more than a collection of oddly shaped stones, but archaeologists have found similar artifacts in Neolithic and Bronze Age settlements, suggesting that humans once inhabited an area now covered by 490 feet (150 meters) of water.

As to the shipwrecks, they include a 2,300-year-old vessel--the oldest ever found in the Black Sea--and additional evidence that naval trade from Greek, Phoenician, and Roman vessels was common on the Black Sea and occurred as early as 450 A.D., during the Byzantine period. Although analysis of these finds has barely begun, in time the Black Sea may come to be regarded as the archaeological equal of ancient Egypt, Greece, or Rome-but only, that is, if scientists like Dr. Ballard are there, beneath the waves, to prove it.
