The movement of nutrient-rich deep seawater to the ocean's surface.

In ocean dynamics, the upward motion of sub-surface water toward the surface of the ocean. This is often a source of cold, nutrient-rich water. Strong upwelling occurs along the equator where easterly [..]

1841, from up (adv.) + present participle of well (v.). As a noun from 1847. A verb upwell is attested from 1885.

The rising of water (usually cold) toward the surface from the deeper regions of a body of water.

process by which currents bring cold, nutrient-rich water to the ocean surface. Read more in the NG Education Encyclopedia

An ascending motion of subsurface water by which water from deeper layers is brought into the surface layer and is removed from the area of upwelling by divergent horizontal flow. See also coastal upw [..]

The rise to the surface of cold, deep ocean waters.

The raising of benthic nutrients to the surface waters. This occurs in regions where the flow of water brings currents of differing temperatures together, and increases productivity of the ecosystem.

the upward flow of cold, nutrient-rich water toward the ocean surface as currents or seasonal winds draw warmer water away from a coast. Phytoplankton that feed in upwellings often support huge fish populations.

Convection currents within a body of water that carry nutrients from bottom sediments toward the surface. uracil

Cold nutrient rich water in the ocean that comes from the depths to the surface and is responsible as a food source for many seabirds

area in the ocean where nutrient-rich bottom water surfaces. It produces blooms of phytoplankton and with it dense populations of fast-reproducing fishes, preyed upon by carnivores, sea mammals and se [..]

the rising of cold deep water to the surface of the ocean; the associated lowering of the sea surface temperature cools the atmosphere and modifies the local climate. The upwelled water is also rich i [..]

brings cold, nutrient-rich water from the depths up to the surface. Earth's rotation and strong seasonal winds push surface water away from some western coasts, so water rises on the western edges of continents to replace it. Marine life thrives in these nutrient-rich waters. Coastal upwelling

The process by which, dense, cold, deep, and nutrient-rich water is brought to the surface of the ocean. Upwelling often results in highly productive ecosystems. For more information click here.

 a current of cold, nutrient-rich water rising to the surface. Upwellings are caused by strong seasonal winds moving surface coastal water out from the coast and leaving a space that the upwelling fills in. Many marine plants and animals live off this nutrient-rich water. Upwelling describes an ocean condition in which the cooler, nutrient-rich wat [..]

A process in which deep, cold water rises toward the surface of the ocean. 

The process by which deep water is brought to the surface (often cold and nutrient-laden). Upwelling can be caused by the wind, divergence of equatorial currents, or coastal winds pushing water away from the coast. (Also see Coastal Upwelling)

wind-driven movement of the ocean, causing cooler denser water to rise to the surface and replace warmer waters. The cool waters are often rich in nutrients and stimulate primary production, which is why upwelling areas are often hotspots for marine life and targeted by commercial fisheries.

The vertical motion of water in the ocean by which subsurface water of lower temperature and greater density moves toward the surface of the ocean. Upwelling occurs most commonly among the western coastlines of continents, but may occur anywhere in the ocean. Upwelling results when winds blowing nearly parallel to a continental coastline transport [..]

An upwelling is an upward movement in the ocean. See section 1.3.2, 5.2.1 and 5.2.3.

This occurs near coasts where winds persistently drive surface water seaward, causing an upward movement of cold, nutrient-rich water from ocean depths, and in the open ocean where surface currents ar [..]

The process by which water rises from a deeper to a shallower depth, usually as a result of offshore surface water flow. It is most prominent where persistent wind blows parallel to a coastline so tha [..]

An area in the ocean typically found near the coast, where cooler, more nutrient-rich water is pushed toward the surface and replaces the warmer, nutrient-poor water. These areas tend to provide a lot [..]

The rising of colder, denser water from deep in the ocean or other body of water to the surface, often as a result of wind-driven surface currents. Upwelling can occur anywhere, but is most common in [..]

Movement of nutrient-rich bottom water to the ocean's surface. This can occur far from shore but usually occurs along certain steep coastal areas, where the surface layer of ocean water is pushed away from shore and replaced by cold, nutrient-rich bottom water.

The process by which cold waters from the depths of a lake or ocean rise to the surface.

The process by which water rises from a lower to a higher depth, usually as a result of divergence and offshore currents. Upwelling is most prominent where persistent wind blows parallel to a coastlin [..]

In ocean dynamics, the upward motion of sub-surface water toward the surface of the ocean. This is often a source of cold, nutrient-rich water. Strong upwelling occurs along the equator where easterly winds are present. Upwelling also can occur along coastlines, and is important to fisheries and birds in California and Peru.

The rise of colder, deep ocean waters along a coast due to the movement of surface water away from the coast.

The process by which water rises from a lower to a higher depth, usually as a result of divergence and offshore currents. It influences climate by bringing colder, more nutrient-rich water to the surf [..]

The upward circulation of cold, nutrient-rich bottom water toward the ocean surface.

the movement of deep, cold, and nutrient-rich water to the surface

The process by which water rises from a lower to a higher depth, usually as a result of divergence and offshore currents. It influences climate by bringing colder, more nutrient-rich water to the surface. A vital factor of the El Niño event.
