If a sudden, intense rainfall event occurs over a highly stratified coastal ocean, which consequence follows regarding nutrient distribution?

💡 Explanation

Intense rainfall creates a surface layer of low-salinity water, increasing stratification. Because increased stratification inhibits vertical advection, the process of vertical nutrient mixing is suppressed, therefore coastal primary productivity suffers, rather than anoxia reversing, or surface salinity increasing.

• A newly formed stratovolcano emits significant sulfur dioxide into the upper troposphere. What happens to surface solar radiation as a consequence?
• What causes higher rates of groundwater infiltration through sandy soil, compared to clay-rich soil?
• What happens to the sediment composition of a coastal mangrove forest when there's an increase in the rate of root pneumatophore growth?
• If a coastline has groynes installed perpendicular to the shore, which consequence follows for sediment distribution due to longshore drift?
• If a coastal barrier island's vegetation is severely reduced by a hurricane, which consequence follows?
• If a volcano erupts effusively, releasing basaltic lava onto a gentle slope, which consequence follows?
