As I understand from your explanation, it is normal to expect a real impedance for seafloor layers while terrestrial soil can have a complex impedance. Thank you very much, your explanations are very helpful.

Thanks Baluncore for your neat explanation. Do you have any comment on ground in contact with air having a complex impedance whereas seafloor has real impedance value? Two references are in the following. https://asa.scitation.org/doi/10.1121/1.2338288...

https://asa.scitation.org/doi/10.1121/1.2338288 This is an example reference. The authors are using existing models to calculate impedance of water saturated sand, which has real and imaginary parts.

berkeman, thank you very much for your help. I have read the second reference already but the first and third ones are new for me. These papers are dealing with the subject in detail but as I explained they are gettin real values for seafloor impedance and I am interested into understand if...

No, as far as I know, it is explained as the phase between pressure and velocity at the ground (or the impedance plane).

Thanks for your explanation but I mean acoustic impedance. I apologize for not making it clear.

There are some mathematical models (eg Delany-Bazley) to calculate impedance of porous materials and these formulas give complex impedance values as a result. But I could not find any model to be used for seafloor (underwater ground modeling) or I don't know if existing models may be used. I...
