what is the effectiveness of a MAD around the poles? There should be a lot of strange magnetic activity around there due to ionizing cosmic rays being redirected there (aurorae) and also you can't drop a sonobuoy under the ice, can you?
To be honest, I'm not sure. That's a little above my pay grade. :-)
I'd imagine you are correct, but I'd assume this has been somehow handled given that we've been using the CP-140 for 30 some years and one of three primary search areas would be north of 60. As I understand it though MAD is pretty much at its peak from a technological perspective. The P-8 doesn't even carry it, afaik.
This thing is "pinging", so I suppose sonar would be the number one choice in terms of tool to use. Again though this is all way over my knowledge level.
