Dr. Lambeck's team used the Roman fish tanks to reach the conclusion that
global ocean volume had not changed much from the Roman era to the 19th century.
And since we have had rising sea level over last couple centuries, and this generally indicates warming
global ocean volume, I expect this trend to continue for the next century [most likely] and due to warming oceans continuation of tread of less polar sea ice.
Based on the linear trend, for the 0 to 3,000 m layer for the period 1961 to 2003 there has been an increase of ocean heat content of approximately 14.2 ± 2.4 × 1022 J, corresponding to
a global ocean volume mean temperature increase of 0.037 °C during this period.

Each

Why it is expected that this miniscule heat speculated as being distributed across the entire
ocean volume, would suddenly give up it's heat, thereby reappearing in the
global surface record.
However, atmospheric CO2 content plays an important internal feedback role.Orbital - scale variability in CO2 concentrations over the last several hundred thousand years covaries (Figure 5.3) with variability in proxy records including reconstructions of
global ice

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 pois

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.
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).
Cazenave, A., D. P. Chambers, P. Cipollini, L. L. Fu, J. W. Hurell, M. Merrifield, R. S. Nerem, H. P. Plag, C. K. Shum, and J. Willis, 2010: The challenge of measuring sea level rise and regional and
global trends, Geodetic observations of
ocean surface topography,
ocean currents,
ocean mass, and
ocean volume changes.
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.
For instance, here's the data for delta - oxygen - 18 from a stack of 57
ocean sediment cores, which is considered an excellent proxy for
global ice
volume, known as the «LR04 stack» (from Lisiecki, L.E., & Raymo, M.E. 2005.
► Eustatic sea - level rise is a change in
global average sea level brought about by an increase in the
volume of the world
ocean.
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.
From historic droughts around the world and in places like California, Syria, Brazil and Iran to inexorably increasing glacial melt; from an expanding blight of fish killing and water poisoning algae blooms in lakes, rivers and
oceans to a growing rash of
global record rainfall events; and from record Arctic sea ice
volume losses approaching 80 percent at the end of the summer of 2012 to a rapidly thawing permafrost zone explosively emitting an ever - increasing amount of methane and CO2, it's already a disastrous train - wreck.
But it only produced about 1 meter of
global sea level rise, assuming an even spread of this
volume spread across the world's
oceans.
In addition, glacial melt from mountain systems, Greenland and Antarctica is contributing ever - increasing
volumes of water to the
global ocean, forcing on the waters» rise at ever - increasing rates.
All of these characteristics (except for the
ocean temperature) have been used in SAR and TAR IPCC (Houghton et al. 1996; 2001) reports for model - data inter-comparison: we considered as tolerable the following intervals for the annual means of the following climate characteristics which encompass corresponding empirical estimates:
global SAT 13.1 — 14.1 °C (Jones et al. 1999); area of sea ice in the Northern Hemisphere 6 — 14 mil km2 and in the Southern Hemisphere 6 — 18 mil km2 (Cavalieri et al. 2003); total precipitation rate 2.45 — 3.05 mm / day (Legates 1995); maximum Atlantic northward heat transport 0.5 — 1.5 PW (Ganachaud and Wunsch 2003); maximum of North Atlantic meridional overturning stream function 15 — 25 Sv (Talley et al. 2003),
volume averaged
ocean temperature 3 — 5 °C (Levitus 1982).
We use realistic estimates of mass redistribution from ice mass loss and land water storage to quantify the resulting
ocean bottom deformation and its effect on
global and regional
ocean volume change estimates.
The
global mean sea level trend is corrected for the Glacial Isostatic Adjustment using the ICE5G - VM2 GIA model (Peltier, 2004) to take into account the associated
volume changes of the
ocean.
The two - day FAMOS workshop will include sessions on 2017 sea ice highlights and sea ice /

The question then becomes one of how much the TOA imbalance may vary by natural climate change and how long it takes the TOA imbalace to be evenly distributed across most of the
volume of the
global ocean.
90 % of the
volume of the
global ocean is at a near constant temperature of 3C.
It doesn't even appear to be enough to raise the temperature of the shallow surface layer by more than a fraction of a degree to say nothing of imparting any significant warmth to the other 90 % of the
volume of the
global ocean below the thermocline (400 + meters deep).
One could choose to look at the
global mean sea level instead, which does have a physical meaning because it represents an estimate for the
volume of the water in the
oceans, but the choice is not crucial as long as the indicator used really responds to the conditions under investigation.
Record droughts in many areas of the world, the loss of arctic sea ice — what you see is an increasing trend that is superimposed on annual variablity (no bets on what happens next year, but the five - to - ten year average in
global temperatures, sea surface temperatures,
ocean heat content — those will increase — and ice sheet
volumes, tropical glacier
volumes, sea ice extent will decrease.
Climate change indicators:
Global Mean Temperature (GMT); Hemispheric Temperature Variance; Greenhouse gases; Arctic, Antarctic Ice Extent and
Volume;
Ocean Oscillations; Sea Level Rise (SLR); Solar Cycle Data; Sea Surface Temperatures and Anomalies;
Global Fire Activity, Drought.
This number is subtracted from altimetry - derived
global mean sea level in order to obtain the contribution due to
ocean (water)
volume change.
