Hi Bernie,
First you compare different aspects of each location - (geophysical) freshw=
ater waves to (ecological) saltwater coastal habitat, which is a little con=
fusing. But it seems you are suggesting the physical differences between f=
resh and salt water also result in unique sound signatures. Biological asi=
de, given two beaches of similar composition and profile, one saltwater and=
the other freshwater, what specific differences might one expect to hear?=
