I. States Considered
There is another way to reveal that thermal expansion is a minor factor in sea level change which varies from the traditional Dredd Blog exploration of the subject.
One technique has been exhausted in non-US state areas (On Thermal Expansion & Thermal Contraction, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51).
Another subject sea level change recorded at tide gauge stations in US states was considered without considering thermal expansion and contraction (The US States of Sea Level Change, 2, 3, 4).
Today, we will use a different, mostly visual, approach and apply it to the following US states (Alaska, California, Delaware, Florida, Hawaii, Louisiana, Maine, Maryland, New Jersey, North Carolina, Oregon, South Carolina, Texas, Virginia, and Washington).
Each state's data is presented in a separate appendix (Florida's Gulf of Mexico and Atlantic Ocean values are displayed in the same appendix, but in separate graphs).
II. Thermodynamics of States
Heat in the ocean is called "potential enthalpy (ho)" in the oceanography language.
That value is considered using Conservative Temperature (CT), Absolute Salinity (SA), and depth pressure (P) and the TEOS-10 library functionality.
Sea level change (rise or fall) is determined by PSMSL tide gauge station measurement records taken at locations along the coast of each US state involved.
Graphs are made of both heat (ho) and sea level so that changes in the two graphs can be compared to see if heat content changes the sea level.
The graphs have a maximum span beginning in the year 1950 and ending in the year 2023.
The three depth levels graphed are Epipelagic, Mesopelagic, and Bathypelagic.
Take a look for yourself to see if you have received accurate information.
III. Closing Comments
Consider the appendices by perusing the three top graphs (CT, Potential Enthalpy, and MOL-photons) graphs first, then compare those lines to the sea level change graph (4tjs or last graph).
The top three graphs detail the heat content in the seawater where the tide gauge stations are (i.e. same WOD zone).
Those sea level change tracks have no relation to the heat content of the seawater, thus, thermal expansion/contraction are minor factors in sea level change.
Just the melting of the ice sheets and the "melting" of ice sheet gravity would cause 80.32 meters (263.5 feet) of sea level change (U.S. Department of the Interior, U.S. Geological Survey).
