Why Galicia has productive coastal waters

Galicia has productive coastal waters because upwelling regularly brings cold, nutrient-rich water toward the surface, where it can support phytoplankton growth and the wider food web. This productivity helps sustain shellfish, fish, seabirds, and marine mammals, and is one reason the Galician coast is so biologically active.
