basically off topic but thread is about to die
https://m.imdb.com/title/tt31971270/This documentary has maybe the worst possible title, simply "Mammals"
I was just watching it just now, they put a GPS thing on a whale and then showed how it navigated around heavy naval traffic.
Wanted to see if there was a clip of that part but it was difficult to find anything, again because of the name of the show.
