For example, plankton does not thrive in
sinking water masses such as those found deep in the North Atlantic, because it is pulled down and away from the light.
In the Norwegian Sea evaporative cooling is predominant, and
the sinking water mass, the North Atlantic Deep Water (NADW), fills the basin and spills southwards through crevasses in the submarine sills that connect Greenland, Iceland and Britain.
Not exact matches
It's here in the frigid Nordic Seas that
water masses become cold and dense,
sinking in streams that snake along the basin bottom, eventually turning southward and reaching the subtropics in about a decade.
We use some of the power to spread the cold
water over the surface so that it does not
sink below the layer where phytoplankton convert dissolved CO2 into organic matter that increases the
mass of their bodies to feed other ocean creatures.
The
mass of
water displaced by various vessels
sunk at sea is far less than the displacement of the vessels.
If that CO2
sinks through a
mass like
water, then why does it magically float in the air, in fact, rising.
If it does
sink through the
mass of
water, then that CO2 in the air should just drop like a stone to the surface of the Planet.
AGW climate scientists seem to ignore that while the earth's surface may be warming, our atmosphere above 10,000 ft. above MSL is a refrigerator that can take
water vapor scavenged from the vast oceans on earth (which are also a formidable heat
sink), lift it to cold zones in the atmosphere by convective physical processes, chill it (removing vast amounts of heat from the atmosphere) or freeze it, (removing even more vast amounts of heat from the atmosphere) drop it on land and oceans as rain, sleet or snow, moisturizing and cooling the soil, cooling the oceans and building polar ice caps and even more importantly, increasing the albedo of the earth, with a critical negative feedback determining how much of the sun's energy is reflected back into space, changing the moment of inertia of the earth by removing
water mass from equatorial latitudes and transporting this
water vapor
mass to the poles, reducing the earth's spin axis moment of inertia and speeding up its spin rate, etc..
For
sinking of a parcel to occur, its
mass density MUST be lower than that of the surrounding
waters.
This is a serious question — the claim of (x +1) degrees of some huge, heated
water mass sinking to the depths without being noticed is absolutely screwy to me
As this
sinking air
mass weighs on the marine layer, the latter compresses into a thin layer with a relatively high concentration of
water vapor.
Eventually the surface
water became denser than the warming deep
water and started to
sink, causing the corrosive deep
water mass to spill over the ridge — overflowing the «giant bath tub».
Is there any likelihood a bloom of plankton (from a freshwater pulse, or fallout of a dust cloud full of minerals, for example) would change the temperature of the surface
water (change the reflectivity, I suppose, or change how much is absorbed by making more complicated molecules for photosynthesis)-- sufficient to make the
water mass density change, affecting whether it
sinks or not?
These dense
water masses spread into the full extent of the ocean and gradually upwell to feed a slow return flow to the
sinking regions.
