Dear Colleagues, I would be interested to know whether anyone is aware of measurements and might be able to share information on the full spectral properties, including frequencies below the center frequencies of the higher (120, 200 kHz etc) signal components of a SIMRAD EK60 scientific echo sounder? We are interested to assess the audibility of these signals to marine mammals and are aware of the paper by Deng et al. 2014, measuring other types of commercial echo sounders, but so far couldn't find similar data for the EK60. Any information would be much appreciated (denise.ri...@sams.ac.uk).
Thanks very much.
