"Following the chance discovery of the wreck in 1982, archaeological excavations were carried out between 1984 and 1994 by George F. Bass and Cemal Pulak of the Institute of Nautical Archaeology. Due to the wreck’s tricky location on a steep rocky slope 50 metres beneath the surface, excavation time for each diver had to be limited to 20 minutes per dive, twice a day. The total number of dives to take place was 22,413."
