[2] The European Institute of Underwater Archaeology (IEASM) works in close collaboration with the authorities of the countries in which it excavates and under their control.
It calls on specialists in the fields of archaeology, history,[3] conservation, restoration, geophysics, geology in its research, to study and publish its findings.
This approach has led to several significant and historically important discoveries such as the display of the antic harbour of Alexandria or the city of Thonis-Heracleion.
[5] The excavations benefit from a conservation-restoration unit on board the mission support boat, allowing the initial stages of object conservation to be carried out on site.
Additional treatments, requiring heavier equipment, take place in local laboratories in collaboration with the institutions concerned.
