Pack Ice, MIZ and the sonar model

I havent done alot testing, but does being under the pack ice or in a marginal ice zone have any effect on sonar?

Under the ice, the ambient sound should be very low. Unless its spring when the the pack ice thaws and begins to break up.

In a Marginal Ice Zone, where large floes and icebergs smash into each other, the ambient noise levels should be very high, making above layer detection rather tough.

Does DW model this in any way? If not, is the sound model capable of modelling this in future releases?
