I've never seen Air tanks that size. Are they some kind of back-up tanks for SCUBA divers or something? It looks like a cool way to get lots of underwater body dolphin practice.
I think the navy use them to escape from sunken submersibles.
An extra terrestial reporting home about the humans would not find the monofins as strange as the waste of perfectly good drinking water.
