Which outcome increases when subtropical gyre currents weaken?

💡 Explanation

Decreased gyre circulation reduces transport into localized upwelling zones, because Eckman transport weakens; therefore coastal upwelling diminishes, rather than increased nutrients from the seafloor flowing into surface waters because of greater current power.
