«If we correct our data to remove [the effect of rising land], it actually does cause the rate of sea level (a.k.a.
ocean water volume change) rise to be bigger,» Nerem wrote.
To extract the signal of sea level change due to
ocean water volume and other oceanographic change, land motions need to be removed from the tide gauge measurement.
Vertical land movements such as resulting from glacial isostatic adjustment (GIA), tectonics, subsidence and sedimentation influence local sea level measurements but do not alter
ocean water volume; nonetheless, they affect global mean sea level through their alteration of the shape and hence the volume of the ocean basins containing the water.

To understand sea - level change means understanding not only the transfer of land ice into the

Sea level rise has two primary components: the expansion in
volume of seawater with increased temperature and the addition of
water in
ocean basins from the melting of land - locked ice, including Antarctica and Greenland.

Through the Lombok straits, between Bali and Lombok flows the Indonesian through flow, a massive
volume of
water that passes from the pacific to the Indian
Ocean.
The parking lot has been shifted so it is perpendicular to the
ocean and the floodplain has been opened up, so that should a large rain event occur, the lagoon will be able to handle the heavy
volumes of
water that flow down Redwood Creek and out to the Pacific.
The changes in
volume over a season also tell us how much ice is produced, how much heat is extracted from the
ocean, how much brine is injected into the
ocean as a result of ice growth and how much melt
water is injected back into the
ocean.
Idea: volcano heated
ocean to increase melt of artic ice:
Volume of
water in artic (about 1 % of world's

Please be precise about the mechanisms,
volumes and timescales, just saying
ocean circulations is not good enough, given what we know about the very long timescales involved to move the
water.
Henry's law doesn't really work well for complex carbonate equilibria and big
volumes of liquid
water, but even as an approximation, let's assume that if we have 38,000 Gt of dissolved inorganic carbon, DIC, (CO2 + HCO3 + CO3) in the
oceans, and the preindustrial CO2 in the atmosphere is about 2,200 gigatons (300 ppm), that's a ratio of about 0.06 (atm /
ocean).
Consider that
oceans surface
water is a tiny part of the complete
ocean volume.
Be thankful that the we are insulated from the huge
volume of cold
waters that comprise the
ocean, because if it ever became far more mixed with the surface layers we would plunge into permanent glaciation.
The
oceans are stratified, warmer
water floats on top of the huge
volume of deeper
ocean that is at maximum density and minimum temperature.
Can we consider the
ocean basin
volume as static for the purpose of sea level change prediction because the speed of

Did you know that
oceans cover three quarters of the Earth's surface, contain 97 percent of the Earth's

volume?
But seen the environmental global CRISIS of GLOBAL WARMING and its devastating climatological impact, I would recommend as an environmental policy - expert that Both NATURAL plankton will be bred in shallow
waters as carbondioxide inhibitors in a large
volume on the one hand and let nature goes its course in the seas and
oceans so that sea - organisms / life - forms / mamals will not become extinct due to (for them) food poisoning.
This is very interesting, not the missing data or that stuff, but the
ocean surface temperature looks to be tightly constrained by the specific
volume of the atmosphere and the freezing points of
water.
It seems that those who fear AGW (or at least some of them) do admit that it is not realistic to expect a planetary atmosphere such as ours to warm up
oceans of
water over the timescale required by AGW theory because of the huge
volume and density of that
water and thus the heat storage differentials.
On decadal and longer time scales, global mean sea level change results from two major processes, mostly related to recent climate change, that alter the
volume of
water in the global
ocean: i) thermal expansion (Section 5.5.3), and ii) the exchange of
water between
oceans and other reservoirs (glaciers and ice caps, ice sheets, other land
water reservoirs - including through anthropogenic change in land hydrology, and the atmosphere; Section 5.5.5).
You continue, «Lets consider LWR (long wave radiation) and SWR (short wave radiation) with LWR not being able to warm a small
volume of
water and especially not the deep
ocean when compared to SWR.
The difference in the role between LWR and SWR on a
volume of the
ocean is like comparing a teaspoon of
water with a swimming pool.
Lets consider LWR (long wave radiation) and SWR (short wave radiation) with LWR not being able to warm a small
volume of
water and especially not the deep
ocean when compared to SWR.
If there's no mixing lower (effective diffusivity = 0) that extra energy only has to warm up a
volume of
water 1/10 as large as the entire
ocean.
Due to the huge
volume of sea
water and the density differentials between air and
ocean that would be impossible or would require such huge amounts of atmospheric heating and such huge lengths of time that for practical purposes it should be ignored.
Ice displacement patterns such as the one below will drive a great
volume of ice out of the Arctic
Ocean and into warmer
waters.
For instance, if global warming were to increase the
volume of
water in the
oceans by causing glaciers or other ice bodies to melt, this would cause the weight of
water in the
oceans to increase.
We saw in Section 2 that
water densities (and hence
volume) are quite variable throughout the
oceans.
The IPCC projections of sea level rise are based largely on the slow, steady and inexorable thermal expansion of the
oceans (as
water heats, its
volume increases) with some additional contributions from the melting of mountain glaciers (almost all of which are expected to be gone by mid century).
Whether it exists as ice or
water, it still has the same mass, it still displaces the same
volume and there's no change in the
volume of the
ocean if it melts.
In summary the melting of land ice floating on the
ocean will introduce a
volume of
water greater than that of the originally displaced sea
water, hence raising the
water level a little.
SLR satellite data includes things such as the «GIA Adjustment» — which is the amount of SLR that there would have been if the
ocean basin hadn't increased in
volume and in the case of this new study, how much higher the sea surface would have been if it had not been suppressed by the Mount Pinatubo volcanic eruption, another correction for ENSO / PDO «computed via a joint cyclostationary empirical orthogonal function (CSEOF) analysis of altimeter GMSL, GRACE land
water storage, and Argo - based thermosteric sea level from 2005 to present», as well as other additions and adjustments — NONE OF WHICH can actually be found manifested in any change to the physical Sea Surface Height.»
Now consider thermohaline currents, hugh
volumes of
water slowly circulating around the world's
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.
As the
ocean warms, the density increasing causing the
water to expand in
volume.
The Atlantic annual formation of deep

«We show, for the first time, that the
volume of rain over land corresponds to the amount of
water evaporated from the unusually warm
ocean,» said lead author Kevin Trenberth, a senior scientist at the National Center for Atmospheric Research (NCAR) in Boulder, Colorado.
Eustatic change (as opposed to local change) results in an alteration to the global sea levels due to changes in either the
volume of
water in the world's
oceans or net changes in the
volume of the
ocean basins.
