Whales that sing or communicate can sing in unison but it isn't that
There are places in the ocean called "sound channels" where it is easy to
communicate with other submarines if they are in the same soound channel.
There is no particular location for these channels. They may be near the
surface or deep. They are a function of temperature and salinity.
Whales certainly make use of these sound channels in the same way that
subs do although it is the whales that taught US how to use them.
Certainly different pods can make use of them but the whales that
communicate over the longest distances are large baleen whales who
communicate in the low frequencies (Blue Whales, Fin Whales) (5 Hz to 25
Hz) which carry farther.
