IB Biology Topic D4.3.5 Changes in Ocean Currents Altering the Timing and Extent of Nutrient Upwelling Revision Notes (SL/HL) | RevisionDojo

Written by official IB examiners

Upwelling feeds the ocean, and climate change is shutting it down

Upwelling acts like an underwater conveyor belt, moving nutrients from the deep ocean up to the sunlit surface where life can use them.

Climate change is disrupting this system, with profound consequences for ocean ecosystems.

Upwelling brings deep, nutrient-rich water to the surface

Definition

Upwelling

The movement of deep, cold, nutrient-rich water to the surface, usually driven by wind and ocean currents.

Upwelling is the process where deep, cold, nutrient-rich water rises to the ocean's surface.
1. Winds push surface water away from the coast.
2. Deeper water rises to replace the displaced surface water, carrying nutrients up with it.

Example

The west coast of South America is famous for upwelling, feeding the phytoplankton that form the base of a rich fishery.

Warming and shifting winds are choking off upwelling
