|Name of project:|
|Mapping the Posidonia Oceanica in the Tuscan Archipelago|
|Country:||Area of study:|
|Consorzio Centro Interuniversitario di Biologia Marina di Livorno (Leghorn Marine Biology Inter-universitary Centre)|
|To identify the presence and extension of Mediterranean Tapeweeds (Posidonia Oceanica) around the smaller islands of the Tuscan Archipelago|
|Composition of the working group:|
|1 photointerpreter, 1 GIS expert|
|In a preliminary phase, the Customer carried out Side Scan Sonar surveys along traverses perpendicular to the coast, in order to define the type of seafloor and the presence of seaweed forests (both Posidonia and other species).
On the basis of this reference data, a photointerpretation of aerial photos was performed, aimed at the integration of the field survey for the mapping of kelp forests and the different sea floor types.
Colour aerial photos, specifically taken with flat sea, were used as the most suitable document for the identification of rock outcrops, sand and Posidonia forests at different density levels.
For the realization of the final maps, the information provided by aerial photos was integrated by sonar depth data in the zones under the penetration limit of colour film (about 15 m) and bathymetric curves were also introduced from the maps of the Italian Navy Hydrographic Institute
