An upwelling is a current in the ocean that brings deep, cold water to the ocean surface.

Ocean convection currents move the deep cold water to the surface of oceans.

An ocean current?
That would be a current, such as a river or ocean current.
The water that forms far below the surface is called a Deep Current.
Surface waters make up about 10% of all the water in the ocean.
Stream like movements of water that occur near the surface of the ocean are called surface currents. Stream like movements of ocean water far below the surface are known as a deep current.
The strong current that brings nutrients up from the ocean floor is known as upwelling. This process occurs when winds blow across the ocean's surface, pushing water away and allowing deeper, nutrient-rich waters to rise to the surface. Upwelling is crucial for marine ecosystems as it supports the growth of phytoplankton, which forms the base of the oceanic food web. Areas of upwelling are often highly productive fishing grounds.
