Which mechanism dictates fjord sill depth controlling deep water renewal in a stratified fjord?

💡 Explanation

When isostatic rebound exceeds eustatic changes after glacial retreat it forms bathymetric sills, because differential uplift raises the land faster than sea level rises, creating shallow entrances restricting water exchange. Isostatic rebound, therefore dictates fjord sill depth, rather than ice plucking, tectonic movement or meltwater, all relating to other geographical properties.
