TeachMeFinance.com - explain upwelling upwelling The term 'upwelling' as it applies to the area of carbon dioxide can be defined as ' 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'. The term 'upwelling' as it applies to the area of the weather can be defined as ' 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 term 'upwelling' as it applies to the area of coastlines can be defined as ' 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.
