Characterizing the acoustic footprint of power generating tidal turbines is necessary to assess possible effects of the radiated noise on local marine life. However, as is the case for a wide range of offshore installations, cohesive and accurate measurement of both the radiated noise of the turbine and the ambient noise conditions is a difficult task. In this case, the usual difficulties with propagation and contaminating noise sources are exacerbated by flow induced noise in the measurement system. Here we present results from noise measurements made of the Ocean Renewable Power Company prototype TidGenTM power generation turbine unit deployed in Cobscook Bay near Lubec and Eastport, Maine. These measurements were made using a drifting measurement system in currents upwards of 6 kn.
