CONF iture;
Will be watching the Seabed Workers position closely over the next few hours. The media's interpretation of what they hear, is not always what is meant.
On the subject of the reanalysis of the SNA "Emeraude" sonar tapes, it would be interesting to know what data recovery technique has been used. I suspect that they have mixed a very low level 37.5kHz tone into the noise which when combined with the pinger 37.5kHz tone will provide (37.5 +/- 37.5) = 75kHz or 0. The level of the tone is critical for the mixing and the summing to take place.
