Ecofriendly protection from biofouling of the monitoring system at Pantelleria' s Cala Gadir underwater archaelogical site, Sicily

Gradually in recent years the emphasis in underwater archaeology has moved from excavation to preservation in situ, making sites accessible to divers through marked trails, and to non-divers via video links. In this context, Sicily's Superintendent of the Sea has, since 2002, at the Cala Gadir archaeological site off the coast of Pantelleria (Fig. 1), established a series of underwater cameras connected to the internet, called the Sistema Integrato per la Tutela dell'Archeologia Subacquea (STARS) (http:// www.progettostars.it).
