We have been running an experimental listening station at Mote Marine Laboratory in collaboration with the Sarasota Dolphin Research Program. The station uses an LS1 board and calculates sound levels in real time and reports them via cell to an online database. It kept running through the hurricane.
It is interesting that sound levels were so low the day before---no pleasure boating. Once we get out there to get the raw data, we will share some wav files.
