Upwelling: Bringing Nutrients to the Surface
Upwelling is a process that brings cold, nutrient-rich water from the deep ocean to the surface. This process is important for marine ecosystems because it provides the nutrients that phytoplankton need to grow. Phytoplankton are microscopic plants that are the base of the marine food web.
