Divers were air supplied from the surface, working 40 mins with a 20 min pure oxygen flush at the 10 mtr deco seat.

Two teams, consisting of 2 divers, 2 tenders and a diving supervisor, rotated during daylight hours, weather permitting. Divers were stood down 24hrs after 7 dives as a safety precaution

Archaeologists working underwater are in constant contact with the Diving Supervisor.
