I. Background
It is difficult to see how much of a cover up of SLC reality the use of the abstract notion of "global mean average sea level" (GMSL) is, unless one compares it to some PSMSL tide gauge station records.
Regular readers know that I have made zones, sub-zones, and sub-sub-zones (see Fig. 1, Fig. 2) of the globe so as to more easily focus on the different dynamics of sea level change (SLC).
That is because SLC is composed of both sea level fall (SLF) and sea level rise (SLR) of highly contrasting degrees, so, mixing them globally obscures the contrasting ups and downs of SLC reality.
On the other hand, using small zones, instead of the entire globe, limits sea level analysis to a small area where the behavior is generally comparable enough so as not to obscure significant SLC factors by using GMSL.
II. Use of Satellite & Tide Gauge Station Data Together
After acquiring the NASA satellite database, I added a routine to the Dredd Blog SLC software model to illustrate this.
 |
| Fig. 3 GMSL vs. ZMSL |
The GMSL data is from the satellite database @ NASA, which anyone can read about or download here.
In the new software module, within the Dredd Blog SLC model, I fuse the satellite data with PSMSL RLR tide gauge station data so the GMSL can be compared to ZMSL.

From then on the ZMSL snakes along, rising above then falling below the GMSL as time goes on.
Notice how generally straight the GMSL is by comparison to the ZMSL.
III. Geophysical vs. Geographical
The misleading impact caused by the misuse of GMSL is also exposed by comparing the geographical components of SLC (Fig. 4) with the geophysical components of SLC (Fig. 5).
 |
| Fig. 5 SLC Geophysical components |
The geographical component sectors indicate where the SLC originated geographically, while the geophysical component sectors indicate the physical type of the SLC.
The "displacement" is ice melt-water, the "ghost-water" is ice-sheet gravity held water that is relocated toward the equator as the ice sheet disintegrates, and the "other" is all other factors (ocean water expansion due to cooling or heating, land surface fall, or rise).
IV. Thermal Expansion
Regular readers know that I criticize scientific papers for their overuse of "thermal expansion" and for their conclusion that it was a "major factor" in SLC dynamics for the past ~200 years (e.g. Questionable Scientific Papers - 4).

| Fig. 6 Physics of water |
My main beef with the error is that SLC is a life and death situation for civilization as we know it.
Toying with it gives an impression that can have catastrophic results in ours, the Anthropocene Epoch, the home of the Sixth Mass Extinction (The Extinction of Robust Sea Ports, 2, 3, The Extinction of Charleston, The Extinction of Philadelphia, The Extinction of Washington, D.C., The Extinction of Boston, The Extinction of Miami, The Extinction of Manzanillo, The Extinction of Houston, The Extinction of Providence, The Extinction of Chesapeake Bay Islands).
We do not have the luxury of status quo"fun science and discovery" that those who came and went before us had.
A mistake with gunpowder in the cowboy days has more leeway than a mistake with a nuclear weapon in our day has.
A mistake with SLC in our day is more critical than a mistake made a couple of hundred years ago.

| Fig. 7Physics of water |
Notice Fig. 7, which shows that water inhabits the space between steam and ice.
Water is at its lowest volume @ 4 deg. C, and from there any change in temperature, whether toward the icy side of life, or towards the steamy side of life, results in expansion of volume.
The warming of an ocean area during the day can cause it to contract, to expand, or both (same with night time dynamics).
Expansion or contraction depends on the temperature at the beginning of any thermal exchange.

| Fig. 8Physics of water |
As it warms up above 4 deg. C it will then expand until the solar input goes away.
Then as it cools at night it will shrink until it reaches 4 deg. C again, when it will begin to expand again if it cools below 4 deg. C (see Fig. 6).
If you take notice of Fig. 8, you see that the expansion is a small percentage compared to the displacement of ice sheet melt-water or icebergs that enter the ocean.
The displacement is 100% of the volume of the ice or water entering the ocean that way.
The "Warming Science Commentariat" tends to express only one side of the life of water doesn't it?
They need to get all Halloween on us and check out ghost-water eh?
V. Conclusion
In closing, I will now tidy up on some other issues in this post.
The difference in Fig. 3 numbers compared to Fig. 4 and Fig. 5 numbers is that Fig. 3 is PSMSL RLR meters, while Fig. 4 and Fig. 5 are the amounts of change taking place in terms of millimeters.
Notice that the pattern is identical because the historical data is identical.
The historical tide gauge values in Fig. 3, as well as the changes shown in Fig. 4 and Fig. 5, are historical PSMSL value ups and downs, all of which are a matter of official record keeping.
BTW, the source of tide gauge station data for Zone AH.SE.NE is listed below, along with the seaports located in that Zone.
The satellite data used to graph the GMSL was set forth here.
