SCIENTIFIC DIVING SECTION
The coastal marine caves are of particular interest by ecological viewpoint due to their location, at the boundary between marine and continental domains, where environmental changes are amplified and recorded by the organisms which are living there. These changes may be detected by the study of several water (i.e. temperature, salinity, pH and Dissolved Oxygen) and sediment (grain size, mineralogy, geochemical composition, etc.) parameters which influence both the benthic communities and the environmental status.

Scientific diving is increasingly being used for numerous studies. Underwater research is particularly important in the natural sciences (geomorphology, ecology, and marine biology) where it allows for the non-invasive observations of habitats, fauna, and flora of aquatic ecosystems. This specific tecnique is useful for acquiring data and samples in underwater conditions, requiring an advanced methodological approach, which is more demanding when the object of the studies are extreme environments, such as marine caves.

Marine caves show unique conditions being not influenced by the environmental variables that regulate the classification of benthic marine populations: light and current. The difficulty of such studies in these complex environments requires the use of scientific diving tecniques, that have become, in recent years, a common methodology for marine biologists. Therefore, this tecnique provides informations about type of species and richness of hard bottom assemblages inside and outside the caves.
