characteristics, and produced a comprehensive species A further 2D drawing, representing a cross section of the Research & development
itinerary, was realised with the aim
of providing a detailed illustration
of geomorphology of the site and
presence and distribution along
depth of the species characterizing
that specific site (Figure 8).
Particular attention was paid to
the legend with a detailed list of
species, seabed characteristics and
icons with fine morphologic details
illustrating species. Different
colours in the legend were used to
represent different taxa (Figure 9).
Those icons were used in the maps
of paths and transects showing the
dive observations.
Each underwater itinerary was
described in detail from surface
to bottom and information about
the principal morphological
characteristics (i.e. rock, shoal,
cave or rocky wall), and other
features (such as depth, current,
exposure to adverse sea-weather
conditions, visibility), useful to
evaluate the difficulty level of
dive, were provided.
Each itinerary was also provided
with a score represented by stars:
the score, from one to four stars,
from low to excellent, was based on
nature conservation relevance, thus
considering biological relevance,
species and habitat presence,
species vulnerability and rarity,
geomorphologic characteristics,
aesthetic view of the itinerary.
Among the itineraries, the most
common topographies observed
