Bioacoustic Characterization of the Mediterranean Sea

Abstract

Aerial and ship-based surveys were carried out to provide baseline information about marine mammal presence, distribution and acoustic behaviour in the Ligurian Sea (Cetacean Sanctuary). Combined acoustic and visual surveys were mainly carried out during the SIRENA cruises organized by Saclantcen within the SOLMAR Project. Acoustic monitoring with towed arrays was performed 24h/day to investigate the diel acoustic patterns. For these purposes, a lightweight wideband towed array and a complete asset for signal recording and analysis, providing high-resolution wide-band processing capabilities, were developed. Databases (strandings, sightings, acoustic contacts, literature) were developed by examining the literature, by collecting data from different organizations, and by conducting field research.
