Hi Rubini, thanks, brilliant!! I guess we don't need whales that jump out the water, just come up for air and maybe float along for a while then submerge again?, so the model wouldn't have to be too perfect as long as it looks the part?
And as soon as you "spot" a surfaced Humpback/blue/grey/wright/mink ( or whatever
) you can run down to the hydrophone room and have a listen, or take photos.
