[Star trek IV] What is up with the Whale Probe?

Where did they come from, why did they care about whales, why did they *only* care about whales, what did the whales from 1986 say that convinced them to leave, where did they go after they talked to some whale?  It made no sense.

It was built by space whales who got wiped out by the Borg.  As to its ultimate purpose, there is only speculation.  It was theorized by Spock to have been sent to investigate the loss of communication with the whales of Earth, whom the space whales may have had contact with in the past.  It could have also been sent to terraform Earth into a Ocean World which the space whales would share with the Earth whales in order to try to escape the Borg.
