deployed, although in most cases this has been after the location of a site. Bass developed the submersible Ishara. Currently, he is working with the small, self-contained submarine Caroline (Figure 3.20), which is being used to investigate the feasibility of submarine survey work (Bass, 2002). In most cases submersibles carrying individuals have now, for obvious reasons, been largely superseded by remotely operated vehicles (ROVs). COMEX has a range of submarines including the REMORA 2000, which combines the functions and instrumentation of an oceanographic subsea vessel with the built-in amenities and design of a recreational submarine.
B. ROVS
Towed video cameras and ROVs (Figures 3.21 and 3.22) are widely used in the investigation of sites that are beyond the operational depths of divers

The submarine is used for survey work and observation during excavations by the Institute of Nautical Archaeology, which is based in Bodrum. It is particularly useful for deep- water survey because there is almost unlimited time as it is at normal atmospheric pressure.
