they are random... not scripted.
even if you go and sit in the prescribed area for a week there is only a % chance you will ever see them
you know... like real life.
i would recommend a winter patrol somewhere in the middle of the BC grid area.
several have been sighted there.
what are you going to do when you locate them? shoot a torpedoe at it? because they dud 100% of the time against bergs... and if you did manage to hit one with a torpedo i dont think there is a damage model.
patience... you will join the ranks of those of us who have seen ice bergs during patrol, give it time, venture deep into the northwestern atlantic... try the denmark strait even.
