Ocean Technology and Talking to Whales

I’ve been accepted into the Bristlemouth Pioneer Program. I’ve been granted a SOFAR Spotter with a Development Kit. I want to build a system capable of autonomously recording whale song (and other ocean data). Humpback Whale songs is incredibly interesting - and scientists have JUST been able to actually talk to whales.

But really getting all “science fictiony” - can we build an ocean phone system to talk to whales?
