As warmer surface waters are carried away by this offshore ocean airflow, cold water from below the thermocline rises to the surface in a process called upwelling.

Upwelled CDW water can be cooled when modified by winter water, or remain warm when it directly accesses a glacier grounding point.

In addition, Alaska oyster farmers are now indirectly affected by ocean acidification impacts farther south because they rely on oyster spat (attached oyster larvae) from Puget Sound farmers who are now directly affected by the recent upwelling of acidic waters along the Washington and Oregon coastline (Ch.

«Changes in basal melting are helping to change the properties of Antarctic bottom water, which is one component of the ocean's overturning circulation,» said author Stan Jacobs, an oceanographer at Columbia University's Lamont - Doherty Earth Observatory in Palisades, N.Y. «In some areas it also impacts ecosystems by driving coastal upwelling, which brings up micronutrients like iron that fuel persistent plankton blooms in the summer.»

Algae's productivity depends on the amounts of nutrients in the water and these nutrients come to the surface by upwelling driven by the winds.

Accordingly, upwelling of waters acidified by anthropogenic CO2 has led to a further decrease in surface pH, as reported in the eastern Pacific Ocean along the west coast of North America, from central Canada to northern Mexico, where shoaling of the layer of seawater undersaturated with aragonite increased the frequency and magnitude of coastal acidification associated with upwelling events (Feely et al. 2008, 2010).

To that you answer if the temperature ever starts to rise, due to say volcanic heat, or upwelling to water's surface, the heat is immediately removed by the power of evaporation as infrared - resonant gases chug heat straight up through the atmospheric mix to belch it out radiatively at higher altitude; while simultaneously dragging other, non-infrared resonant gases upward with them, to also dump THEIR heat radiatively, from a higher position than they would have, had the refrigerative cycle not taken place.

A modelled simulation of the California Current upwelling region (Gruber et al. 2012) forecasts that summer - long undersaturation will occur in the top 60 m of the water column by year 2040 and that by 2050 aragonite saturation states greater than 1.5 will have disappeared, driving more than one half of the water column to undersaturation year - round.

Stronger downward transport of water mass must be balanced by upwelling somewhere else, and this occurs in regions of divergence (Ekman suction)- along the equatorward travelling arms of the gyres, and along the equator itself.

One possibility that has been discussed by Emanuel and others is the fact that the warming of the upper ocean may be inhibiting the negative feedback associated with upwelling of colder sub-surface water due to wind stirring.

Reduced equatorial cloud cover during La Nina (due to the cooler sea surface temperature), combined with the strong upwelling (Ekman suction) in the eastern equatorial Pacific, does indeed lead to greater warming of the ocean - because it's bringing cool subsurface water to the surface, where it can be heated by the sun.

(That cooler upwelled water is then warmed by the La Niña - caused additional sunlight as it travels from east to west across the tropical Pacific, and it collects in an area east of Indonesia called the west Pacific Warm Pool, where it warms the ocean heat content of the tropical Pacific.)

They explain the lesser warming in the East Pacific Ocean, near South America, as being due to the fact this region is kept cool by upwelling, rising of deeper colder water to shallower depths.

Two modes of ocean circulation are considered: a thermohaline overturning cell, essentially vertical, which involves global scale upwelling into the surface followed by sinking in deep water formation regions; and an approximately horizontal cell which connects the abyss directly with deeply convecting waters in deep water formation regions.
