Research subject/title:
Acoustic Monitoring with the deep platform NEMO-ONDE

Project coordinator / institution in charge:
CIBRA, University of Pavia & INFN-LNS Catania

ACCOBAMS Priority number (VIEW):
0

Project description:
Within the large NEMO Project, an experimental deep station, named ONDE, has been deployed on the sea bottom 21 km offshore Catania (Sicily, Italy), at 2000 m depth, at the end of January 2005. Connected to the shore labs through electro-optical cables to provide real-time monitoring and data acquisition, it was continuously operative in the periods April-December 2005 and June-November 2006. Four calibrated broad-band hydrophones, sampled at 96 kHz, sent digital data to the shore lab 24/24h; as the continuous recording was not possible due to storage space constraints (uncompressed recording would require 124GB/day), recordings were made for 5 minutes every hour. For short periods of time it was also possible to record continuously to test the sampling strategy. The experiment provided long term data on the underwater noise and an unique opportunity to study the acoustic emissions of marine mammals living in the area or passing through it. Data analysis is in progress to accurately map the presence and movements of sperm whales.
