Which outcome occurs when a fjord's sill restricts deepwater exchange?

💡 Explanation

Anoxic conditions develop due to density stratification preventing oxygen replenishment from surface waters; this stagnation results from limited Circulation Restriction because the sill impedes the water movement. Therefore, deoxygenation results rather than tidal effects or changed sedimentation.
