I've been experimenting with T10 dextran coated iron oxide nanoparticles, obviously not the same as fullerenes, but still a very interesting tool, I've been testing if the coating is giving the particle antioxidant abilities because of it's the (basically) indigestable sugar chains (glucose) creating a high
surface area which are largely made
from hydroxyl groups, I hypothesised this act's as a «
sink» for reactive oxygen species converting them to
water.
In addition, reductions in calcification
from lowered pH in
surface waters could reduce phytoplankton
sinking rates through loss of ballast (Hofmann and Schellnhuber, 2009), though this effect will depend on the ratio of the fraction of ballasted vs. un-ballasted fractions of the
sinking POC.

I suspect the amount of additional 33psu
surface waters entrained by the
sinking brine is indicated by the nearly 35psu salinity of Arctic ocean
water below about 300 meters depth; if the salt
from each cubic meter of ice formed were added to approximately 15 cubic meters of
water at 33psu, it would raise the salinity to near 35psu.
The
sinking is mainly driven by the saltiness of the
water, which is affected by evaporation of fresh
water from the
surface or, particularly in the Arctic, freezing seawater which leaves salt behind in the
water beneath the ice.
The system is vulnerable because even a relatively small decrease in
surface salinity prevents
water - no matter how cold it is -
from sinking.
This discourages
surface water from sinking downwards into the deep ocean.
Based on evidence
from Earth's history, we suggest here that the relevant form of climate sensitivity in the Anthropocene (e.g.
from which to base future greenhouse gas (GHG) stabilization targets) is the Earth system sensitivity including fast feedbacks
from changes in
water vapour, natural aerosols, clouds and sea ice, slower
surface albedo feedbacks
from changes in continental ice sheets and vegetation, and climate — GHG feedbacks
from changes in natural (land and ocean) carbon
sinks.
Cold
water in clouds is the nearest
sink that absorbs the CO2 that is outgassed
from the
surface of the ocean.
Climate Alchemy and probably most scientists not taught chemical thermodynamics don't realise that the main heat transfer term in the oceans is the partial molar enthalpy transferred when the fresh, cold
water sinking from melting ice in the Antarctic and Arctic summers is made more saline when it mixes with the warmer, more saline
surface water for which solar energy has partially unmixed the ions.
5) As a consequence, the partial pressure of CO2 has been rising in these as
sinks acting
surface waters, which has been making CO2 absorption
from the atmosphere to the sea
surface sinks become slower.
From Houston: «Even after switching to
surface water, the ground will continue to
sink for several years, Kasmarek said.
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 more than a decade, researchers have struggled and failed to balance global carbon budgets, which must balance carbon emissions to the atmosphere
from fossil fuels (6.3 Pg per year; numbers here
from Skee Houghton at Woods Hole Research Center) and land use change (2.2 Pg; deforestation, agriculture etc.) with carbon dioxide accumulation in the atmosphere (3.2 Pg) and the carbon
sinks taking carbon out of the atmosphere, especially carbon dioxide dissolving in Ocean
surface waters (2.4 Pg).
Either this is a truism (the sun must be heating the ocean
surface first) or it is meant to take into account the complex circulations that occur in the ocean, like the Gulf Stream's involvement in a vertical rise of
waters from deep ocean layers in one region and
sinking of the cooled
surface waters as the stream reaches its northern limit.
Indeed, the density buildup
from salt excess and evaporative cooling is what causes the North Atlantic
surface waters to
sink so dramatically.
Land subsidence, a phenomenon in which the land
surface sinks, is sometimes caused by the removal of
water from geothermal reservoirs.
In principle, a large enough return flow of fresh
water from rivers and glaciers could reduce the density of the
surface waters sufficiently to stop them
from sinking, in which case the whole AMOC would stop.
Historically, large columns of very cold, dense
water in the Greenland Sea, known as «chimneys,»
sink from the
surface of the ocean to about 9,000 feet below to the seabed.
As a consequence, the partial pressure of CO2 has been rising in these as
sinks acting
surface waters, which has been making CO2 absorption
from the atmosphere to the sea
surface sinks become slower.
If cold
water rises to the
surface warm
water from the
surface must
sink to displace it otherwise an empty vacuum would have to somehow form at the point of origin for the upwelling cold
water.
This fresh
water from Greenland is lighter than saltwater, so it stays on the
surface, preventing saltwater
from sinking, which begins to inhibit the current, slowing it.
Cold
water sinks readily in polar regions, as the
surface water tends to be closer to freezing, as well as being fresher
from ice melt, and therefore less dense than the inflowing currents, which are in turn are rendered more saline by the fresh
water freezing out.
As the
surface water cools at night through evaporation it gets denser and
sinks while warmer
water from below rises to replace it.
The scientists estimated that the swarm consumed up to 74 percent of microscopic carbon - containing plants
from the
surface water per day, and their
sinking fecal pellets transported up to 4,000 tons of carbon a day to deep
water.
re # 39 Lynn Remember that the ocean is heated
from the
surface, and that warmer
waters would have less tendency to
sink.
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?
This system involves the
sinking of cold saline
waters in the subpolar regions of the oceans, an action that helps to drive warmer
surface waters poleward
from the subtropics.
