Upwelling - Wikipedia
Upwelling is an oceanographic phenomenon that involves wind-driven motion of dense, cooler, and usually nutrient-rich water from deep water towards the ocean surface. It replaces the warmer and usually nutrient-depleted surface water.
What is upwelling? - NOAA's National Ocean Service
Jun 16, 2024 · Upwelling is a process in which deep, cold water rises toward the surface. This graphic shows how displaced surface waters are replaced by cold, nutrient-rich water that “wells up” from below. Conditions are optimal for upwelling along …
Upwelling - National Geographic Society
Dec 9, 2024 · Upwelling is a process in which currents bring deep, cold water to the surface of the ocean. Upwelling is a result of winds and the rotation of the Earth.

Mar 30, 2023 · Upwelling refers to an oceanographic phenomenon that includes the wind-driven movement of cool, nutrient-rich, dense waters from deeper ocean depths toward the ocean surface to replace the warm, nutrient-depleted surface water.
NOAA Ocean Explorer: Sanctuary Quest: Background
The ecological effects of upwelling are quite diverse, but two impacts are especially noteworthy. First, upwelling brings up cold, nutrient-rich waters to the surface, which encourage seaweed growth and support blooms of phytoplankton.
9.9: Upwelling and Downwelling - Geosciences LibreTexts
Feb 15, 2021 · Upwelling is the vertical movement of cold, nutrient-rich water from deep water to the surface, resulting in high productivity (plankton growth). • Can bring cold, nutrient-rich water to the surface (photic zone) unless thermocline is strong and prevents it.
9.5 Currents, Upwelling and Downwelling – Introduction to …
Upwelling occurs where surface currents are diverging, or moving away from each other. As the surface waters diverge, deeper water must be brought to the surface to replace it, creating upwelling zones. The upwelled water is cold and rich in nutrients, leading to high productivity.
What Is Upwelling? - WorldAtlas
May 3, 2018 · Upwelling is a phenomenon that occurs in the ocean when the strong wind drives cooler, denser water from a lower surface in the ocean to the upper surface. In the process, the warmer water which is on the surface is moved to the bottom and is …
What causes upwelling? - Geographic Pedia - NCESC
Feb 24, 2025 · Upwelling is a fundamental oceanographic process that shapes marine ecosystems and influences global climate. Driven by winds, the Coriolis effect, and coastal geography, this upward movement of nutrient-rich water forms the basis of many of the world’s most productive fisheries.
What is upwelling? - NOAA Ocean Exploration
Upwelling occurs when winds push surface water away from the shore and deeper water rises to fill the gap. During upwelling, wind-displaced surface waters are replaced by cold, nutrient-rich water that wells up from below.
