the oceanographic phenomenon that occurs when strong, usually seasonal, winds push water away from the coast, bringing cold, nutrient-rich deep waters up to the surface
an upward movement from a lower source
{i} process of sea water rising toward the surface from the bottom of the sea (Oceanography)
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 is usually induced by Ekman transport (see below) Large-scale equatorial upwelling results at the equator due to the divergence of the Ekman transports at the Equator The trade winds predominantly blow from east-to-west in the tropics In the N Hemisphere, this leads to an Ekman transport poleward to the north and in the S Hemisphere, poleward to the south Deeper, colder and more nutrient rich waters replace the poleward moving surface waters (add figure)
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 that the resultant Ekman transport moves surface water away from the coast
The rising of cold water from the deeper areas of the ocean to the surface This phenomena often occurs along the California coast during the summer
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 the light surface water away from the coast Subsurface water of greater density and lower temperature replaces the surface water, and exerts a considerable influence on the weather of coastal regions Carbon dioxide is transferred to the atmosphere in regions of upwelling This is especially important in the Pacific equatorial regions, where 1-2 GtC/year may be released to the atmosphere Upwelling also results in increased ocean productivity by transporting nutrient-rich waters to the surface layer of the ocean (Source: Carbon Dioxide Information Analysis Center, 1990)
an upward flow of cold, heavy deep-sea water caused as offshore currents draw away warm surface water The deep-sea water of upwellings is generally rich in nutrients
The rising of cold water from the deeper areas of the ocean to the surface
The movement of nutrient-rich deep seawater to the ocean's surface
A process where water flows from below to above Used to describe water flow in egg trays and filters, as well as the phenomenon where nutrient rich deep waters rise to the surface (see stratification)
The rise to the surface of cold, deep ocean waters
a process by which water rises from lower depths into the shallows, usually the result of divergence or offshore currents
Convection currents within a body of water that carry nutrients from bottom sediments toward the surface
Currents that bring nutrient-rich bottom water up to the surface layers of water
regions of the ocean that transport deep water up to the surface These regions are important as they bring nutrient-rich deep water to the surface that lead to greater biological productivity
The rising of cold water from the deeper areas of the ocean to the surface This phenomena often occurs along the California coast during the spring and summer
A process in which cold, often nutrient-rich waters from the ocean depths rise to the surface
the process by which warm, less dense surface water is drawn away from a shoreline by offshore currents and replaced by cold, denser water brought up from the subsurface
The rising of water toward the surface from subsurface layers of a body of water Upwelling is most prominent where persistent wind blows parallel to a coastline so that the resultant wind-driven current sets away from the coast ( see Ekman spiral ) It constitutes a distinct climatogenetic influence by bringing colder water to the surface = Over the ocean, upwelling occurs wherever the wind circulation is cyclonic , but is appreciable only in areas where that circulation is relatively permanent It is also observable when the southern trade winds cross the equator The upwelled water, besides being cooler, is richer in plant nutrients, so that regions of upwelling are generally also areas of rich fisheries
Term used to describe the process by which cold, nutrient-rich water comes up to the surface to replace water that has moved horizontally to some other region The world's major fisheries coincide with regions of upwelling
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 movement of nutrient-rich water from a specified depth to the surface
refers to the process, common along continental coastlines, in which nutrient-laden waters from the ocean depths rise to the surface Upwelling typically occurs when prevailing winds force warm surface waters away from the coast Cold, deep water then rises, or upwells, to replace the wind- displaced surface water, bringing with it rich supplies of nutrients and causing an increase in the production of living organisms
The rise of deep, cold, dense water The deep water rises to replace the wind displaced surface water, and is nutrient rich
upwell
To rise from a lower source; to well up
upwell
{f} well up, flow or move upward
