Abstract:
Acoustic noise levels were measured in the Gulf of Catania (Ionian Sea) from July 2012 to May 2013 by a low
frequency (< 1000 Hz) hydrophone, installed on board the NEMO-SN1 multidisciplinary observatory. NEMOSN1
is a cabled node of EMSO-ERIC, which was deployed at a water depth of 2100 m, 25 km off Catania. The
study area is characterized by the proximity of mid-size harbors and shipping lanes. Measured noise levels were
correlated with the passage of ships tracked with a dedicated AIS antenna. Noise power was measured in the
frequency range between 10 Hz and 1000 Hz. Experimental data were compared with the results of a fast
numerical model based on AIS data to evaluate the contribution of shipping noise in six consecutive 1/3 octave
frequency bands, including the 1/3 octave frequency bands centered at 63 Hz and 125 Hz, indicated by the
Marine Strategy Framework Directive (2008/56/EC).
