Which risk increases when a rapidly growing barrier island impedes normal longshore drift against a recessed bay?

💡 Explanation

Increased seabed sediment anoxia becomes more prevalent because the interruption to the longshore drift reduces water circulation within the enclosed bay, leading to stagnation; therefore, oxygen depletion rises, rather than other atmospheric or lithospheric processes occurring.
