Which risk increases within fjord sediment when reduced tidal flushing occurs?

💡 Explanation

Increased concentration of reduced substances causes increased dissolved organic matter oxidation because limited water exchange reduces oxygen replenishment through advection, causing an oxygen deficit therefore sulfide oxidation increases rather than nutrient exchange.
