Which outcome results where isostatic depression exceeds sediment infill in fjords?

💡 Explanation

Deep, anoxic basins develop because isostatic depression lowers previously glaciated land, causing seawaters to flood extensively; saline stratification limits mixing, capping denser bottom layers, therefore the basin is anoxic, rather than estuarine.
