Which outcome commonly occurs near continents within anticyclonic oceanic gyres?

💡 Explanation

Coastal upwelling occurs because Ekman transport moves surface water offshore, and this must be replaced by water rising from depth. This process draws deep, nutrient-rich water upwards, therefore increasing biological productivity rather than reducing rainfall.
