Back in the day I was an acoustic engineer and as part of an EIR (environment impact report) that is needed for the development of one of the salt marshes we had to go out on the salt pond levy's and setup sound level meters.

Two take aways from spending time out on the salt ponds.

1) They smell really really bad.

2) The soil is still very wet even in areas that look like solid ground. I nearly lost a shoe when my foot sank into this deep muck.

Moral of the story: better to view these ponds from afar.
