In Tom Clancey's non-fiction book "Submarines" a nuclear sub went missing after 
leaving the Mediterranean in the late sixties. An engineer found the records 
from three hydrographical recordings (from Newfoundland and the US) and was 
able to pinpoint the breakup sounds of the sub two thousand miles away using 
triangulation. He also pinpointed it within two hundred meters. It would not be 
surprising if some whales can hear as well or better than hydrophones!
