What is the strong current that brings nutrients up from the ocean floor?

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.
