What is upwelling? - NOAA's National Ocean Service
WEBJan 20, 2023 · 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 the coast when winds blow along the shore.

WEBJan 2, 2024 · noun. movement of air (from a high pressure zone to a low pressure zone) caused by the uneven heating of the Earth by the sun. 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.
Upwelling - Wikipedia
WEBUpwelling 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 Ocean Exploration
WEBUpwelling 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.
NOAA Ocean Explorer: Sanctuary Quest: Background
WEBFirst, upwelling brings up cold, nutrient-rich waters to the surface, which encourage seaweed growth and support blooms of phytoplankton. The phytoplankton blooms form the ultimate energy base for large animal populations higher in the food chain, including fish, marine mammals and seabirds.

Upwelling - Currents: NOAA's National Ocean Service Education
WEBUpwelling. Currents Tutorial. Winds blowing across the ocean surface often push water away from an area. When this occurs, water rises up from beneath the surface to replace the diverging surface water. This process is known as upwelling.
Ocean Upwelling | Center for Science Education
WEBOcean Upwelling. In areas of upwelling, deep ocean water makes its way to the surface. This has an impact on marine life as well as the region's climate. Upwelling happens commonly along coastlines. Winds blowing parallel to a coastline cause water at the ocean surface to moves at about a 90 degrees angle from the wind direction (to the right ...
