Which consequence results when deep ocean productivity declines in a gyre?

💡 Explanation

Altered thermohaline circulation results because reduced surface productivity decreases the density of descending water through the process of nutrient cycling; therefore, deep water formation weakens, rather than enhancing upwelling which is driven by wind patterns.
