In July 2007 Nauta-rcs was asked to perform an underwater acoustic noise level assessment in the Messina Strait (Italy) in order to create a baseline noise profile for this environment. CIBRA - Centro Interdisciplineare di Bioacustica e Ricerche Ambientali of the Pavia University, also offered supervision to this assessment, and offered help and instruments.
These data were needed to compare standard noise levels in the area with new readings as those obtained with an operational Kobold turbine. Kobold turbine is a patented energy producing floating system today under tests in the Messina Strait.
Messina Strait is a small, rather deep and with heavy ship traffic strait that separates the most southern peninsular Italy from Sicily. The strait connects south Mediterranean Sea with the Tyrrhenian Sea.
