Currents and the formation of sinking
dense waters transport the carbon between the surface and deeper layers of the ocean.
Not exact matches
Warm and saline
water transported poleward cools at the surface when it reaches high latitudes and becomes
denser and subsequently sinks into the deep ocean.
Cold, polar
waters constantly absorb CO2, sink as it becomes more
dense, and is
transported to the equatorial
waters via the ThermoHaline and outgases in the warmer
waters of the Indian and Pacific Oceans.

A greater - than - normal volume of warm salty tropical
water was
transported north with the current and this was drawn down into the ocean in the region around 60 ° N - where
dense water sinking occurs.
The Atlantic Meridional Overturning Circulation (AMOC)- the
transport of warm tropical surface
water northward - is indeed propelled by
dense water sinking in the North Atlantic and travelling equatorward in the deeper layers, but it also has a wind - driven component to it.
Icelandic scientists say they have discovered a new overturning site, where cold,
dense, deep
water is formed and
transported through a separate route towards the Denmark Strait and further south into the Atlantic Ocean.
All that is needed is to add heat carried upwards past the
denser atmosphere (and most CO2) by convection and the latent heat from
water changing state (the majority of heat
transport to the tropopause), the albedo effects of clouds, the inability of long wave «downwelling» (the blue balls) to warm
water that makes up 2 / 3rds of the Earth's surface, and that due to huge differences in enthalpy dry air takes far less energy to warm than humid air so temperature is not a measure of atmospheric heat content.
Because saltier
water is
denser and thus more likely to sink, the
transport of salt poleward into the North Atlantic provides a potentially destabilizing advective feedback to the AMOC (Stommel, 1961); i.e., a reduction in the strength of the AMOC would lead to less salt being
transported into the North Atlantic, and hence a further reduction in the AMOC would ensue.
The Gulf Stream
transported salt to the North Atlantic, making
waters there
dense enough to sink and drive the lower limb of the Conveyor.
