The Hublot team use small, spherical underwater drones – called Bubblots – to investigate the sea floor. These Bubblots aspire water that is then analyzed by Metrohm VA (voltammetry) analyzers on board. If higher metal salt concentrations are detected, it is safe to assume that there must be some metal object nearby under the floor.
With this method, the Hublot team can efficiently scan the sea floor and identify areas worth having a closer look at. The main goal, of course, would be to find missing parts of the Antikythera mechanism.
