No, we haven't had much discussion on this because from what I understand, it's very difficult to put a device on the whales that will stay on them so you can follow them. That's one of the points.
We've been testing some intelligent buoys. If those buoys get entangled in rope with a whale, they send real-time messages. That is an improvement in terms of mitigating the entanglements and allowing rescuers to liberate a whale.
