Which effect primarily results when coastal upwelling significantly diminishes due to weakened trade winds?

💡 Explanation

When upwelling weakens, nutrient transport from deep ocean layers to the surface reduces because the driving mechanism is reduced vertical water movement, leading to nutrient depletion. Therefore decreased nutrient availability ensues rather than other ecological outcomes, which depending on different physical drivers.

• Which pattern results when differential ice ablation occurs?
• Which outcome occurs when increased glacial meltwater streams significantly freshen North Atlantic surface waters?
• Which pressure distribution does the coastal rain shadow effect require to form?
• Following river avulsion, which process consolidates sediment during oxbow lake formation?
• Which outcome results when intense rainfall strikes thick loess deposits?
