You weren't trying to imply that this could have an impact, were you?
Your argument is logical, but the ocean is warmed by the sun. Depending on the number of boats Google would plan to deploy, I very much doubt this net cooling effect would make any difference to the temperature of the ocean in the long run (changes in ocean currents and other such phenomena will have a much more lasting impact). At least, no more so than in existing ships, that use water cooling systems in their engines.
Any SSH daemon listening on the public network should already be locked down to a basic level (denyhosts, changed port, IP-based access controls) in any case. I guess some installations will not be able to implement all of these but they are in the minority.
I'd take an educated guess at the vast majority of SSH daemons being used for remote administration; at the very least the controls mentioned above should be in place! Sure, this won't make you invulnerable, but the default denyhosts configuration alone (iirc) will limit the number of keys an attacker can try before he is locked out and an admin is notified.
