Bioacoustic Characterization of the Mediterranean Sea
The goals of this project are the
classification of species-specific sounds of cetaceans
occurring in the Mediterranean Sea and adjacent waters;
the understanding of marine mammals' behavior in relation
to the sounds they emit, the study of their ecological
role and of their habitat use according to local
oceanography, the study of their critical habitats and of
their sensitivity to human activities, the evaluation and
monitoring of noise sources possibly affecting cetacean
hearing and behavior, the development of acoustic methods
for the detection, monitoring and census of animals.
Within the project CIBRA collected, by using its own recording and analysis system, a huge amount (more than 2 TB) of digital sound recordings from a number of different sensors (towed arrays, single hydrophones, sonobuoys, bottom deployed recorders). All the recordings are stored in digital formats on hard disk to be easily accessed for listening and analysis. All files are time and georeferenced; spreadsheet indexes and GIS maps with 1 minute time accuracy allow an easy retrieval of interesting cuts based on date and time, sound category or location. The library is now the most important archive in Europe to be used for biological research (species and individual recognition and classification), for developing and testing automatic call recognition programs, for education and training, and also for designing and testing new equipment for sound detection and analysis. The library is now being fed by the underwater test station ONDE within the frame of the NEMO Project.

Spectrogram of a FM sonar and striped dolphin's whistles and clicks (CIBRA, Ligurian Sea, 1996).
GIS map of strandings of Ziphius cavirostris recorded in the Mediterranean Sea in the last 160 years. This work was mainly made in cooperation with the Natural History Museum of Milan (Italy) within the SOLMAR Project.
