OP here.  This popped up elsewhere, thought I&#x27;d share.  I&#x27;m a bit annoyed though because all this does is show that we can take sonar reflections and create an image from them, doesn&#x27;t say anything about what the dolphin is doing with it.<p>It would be a much more interesting experiment to look at just applying the same imaging algorithm to non-location noises (just dolphin chatter) and see what it looks like.
