On Thermal Expansion & Thermal Contraction - 7

Fig. 1 WOD Zones @ Equator
Today we take a look at the World Ocean Database (WOD) zones along the equator.

One strip of zones is in the N. Hemisphere and the other is in the S. Hemisphere, yet they have the common boundary we call the equator.

I chose these zones because the thermal expansion hypothesis (TEH) has been quoted as indicating that "thermal expansion is responsible for MOST sea level rise for the past century."

If you read much on the subject of sea level rise by now you have read that assertion many times.

It is a myth, a falsified hypothesis.

I have been testing that hypothesis using the data (available to anyone who wants to check it out) from the WOD.

It would seem that the water along the equator would be a prime example of thermal expansion and warm water just like in a bathtub if the hypothesis holds water (see e.g. The Warming Science CommentariatOn Thermal Expansion & Thermal Contraction, The Bathtub Model Doesn't Hold Water, 2).

The graphic at Fig. 1 is the WOD global zone map, and Fig. 2 is a graph of the temperatures of the ocean water from the surface to the deepest temperature measurements made from about 3000 meters deep, on down to the bottom (and made from millions of measurements).

The years range from 1961 to 2016 (~55 yrs) in these WOD zones: (1000, 1001, 1002, 1003, 1004, 1005, 1006, 1007, 1008, 1009, 1010, 1011, 1012, 1013, 1014, 1015, 1016, 1017, 3000, 3001, 3002, 3003, 3004, 3005, 3006, 3007, 3008, 3009, 3010, 3011, 3012, 3013, 3014, 3015, 3016, 3017, 5000, 5001, 5002, 5003, 5004, 5005, 5006, 5007, 5008, 5009, 5010, 5011, 5012, 5013, 5014, 5015, 5016, 5017, 7000, 7001, 7002, 7003, 7004, 7005, 7006, 7007, 7008, 7009, 7010, 7011, 7012, 7013, 7014, 7015, 7016, 7017 [those with strike are over land]).

There is nothing in the data to support the TEH, and if anything it debunks the myth.

The ocean is a vast storage area that can take a lot of heat without net expansion.

That is because the ocean also contracts (shrinks) when warmth is added to water that has a temperature below the maximum density temperature (4 deg. C for pure water).

In fact, the ocean depths where the coldest water is even contracts if heat is added to it when it is at certain temperatures.

I chose the location in today's post because the equator is where we should see the demonstration of thermal expansion causing "MOST" sea level rise for a century, but we do not.

Which reminds me once again that the very abundant ghost-water seems to still be invisible to those who do not want to see it (The Ghost-Water Constant, 2, 3, 4, 5, 6, 7).
