Radiocarbon dating animation
carried out on the ship's cargo--salted catfish steaks stored in Greek clay amphorae--has already shown that the vessel sank during the 4th or 5th century BC, making it the oldest wreck to be discovered in the Black Sea region.A Greek ship that may once have supplied fish to Alexander the Great's army and the markets of Athens has been found off the coast of Bulgaria by Dr Robert Ballard, the deep-sea explorer who found the wrecks of the Titanic and Bismarck.He also discovered that tritium similarly could be used for dating water, and therefore wine.In 1950, he became a member of the General Advisory Committee (GAC) of the Atomic Energy Commission (AEC).
On December 8, 1941, the day after the Japanese attack on Pearl Harbor brought the United States into World War II, Libby volunteered his services to Nobel Prize laureate Harold Urey.Atomic Energy Commission (AEC) Chairman Gordon Dean appointed Libby to its influential General Advisory Committee (GAC) in 1950.In 1954, he was appointed an AEC commissioner by President Dwight D.In January 1956, he publicly revealed the existence of Project Sunshine, a series of research studies to ascertain the impact of radioactive fallout on the world's population that he had initiated in 1953 while serving on the GAC.Libby resigned from the AEC in 1959, he became Professor of Chemistry at University of California, Los Angeles (UCLA), a position he held until his retirement in 1976. In 1962, he became the Director of the University of California statewide Institute of Geophysics and Planetary Physics (IGPP), a position he also held until 1976.
Tests against sequoia with known dates from their tree rings showed radiocarbon dating to be reliable and accurate.
