Which process sharply restricts nutrient availability specifically within deep fjord basins?

💡 Explanation

Sill-induced stratification limits nutrient mixing because a raised sill restricts deep water exchange. This prevents oxygen replenishment, potentially leading to anoxia; therefore, nutrient cycling is drastically reduced, rather than enhanced by upwelling.
