The Photon Curennt - 20

Fig. 1 Stairway to hell?

In Episode 15 of this series I suggested that if the Second Law of Thermodynamics was not operational serious temperature changes would be observed in the upper ocean depth levels.

The GISSTEMP dataset values were used to illustrate the point being made (Fig. 1).

The thought came to mind that perhaps the phenomenon of The Photon Current could be altered by physical factors which alter the operations of the Second Law of Thermodynamics.

Remembering the contrast drawn between Fig. 1 and Fig. 2 discussed in Episode 15, a quickie supposition came to my mind, which was "heat saturation?".

Fig. 2 Thank you 2nd Law

So, I posed the following question to the Google AI algorithm:

"What factors determine at what temperature, pressure, salinity, and depth infrared photons in molecules of seawater will radiate to a molecule in cooler seawater near it?"

In that aforesaid episode I was in the state of mind of being appreciative of the operation of the Second Law of thermodynamics.

That is because the climate impact to global temperatures if it was not in existence would be catastrophic.

The surprising increase in global temperatures would be one event that would take place if the oceans became somehow "saturated" with heat to the  point of not absorbing as much or even radiating the heat into the atmosphere instead of radiating it as a photon current downward to previously cooler water.

Anyway, here is what "AI dood" had to "say" ...

AI Overview

The factors determining at what temperature, pressure, salinity, and depth infrared photons will move to a molecule in colder water are primarily the water molecule's vibrational and rotational energy levels, which are influenced by temperature and pressure, as well as the presence of dissolved salts (salinity) that can further affect the absorption spectrum; essentially, colder water with higher pressure and salinity will absorb infrared photons at slightly different wavelengths due to changes in molecular interactions and density.

Key points to consider:

Temperature:

As water cools, its molecules have less kinetic energy, leading to a shift in the absorption spectrum towards longer infrared wavelengths due to increased hydrogen bonding between water molecules.

Pressure:

Increasing pressure compresses water molecules closer together, slightly altering their vibrational modes and influencing the absorption of infrared radiation.

Salinity:

Dissolved salts in seawater can introduce additional absorption peaks in the infrared spectrum, further affecting how infrared photons interact with water molecules.

Depth:

As you go deeper in the water column, the pressure increases, which can slightly influence the absorption of infrared radiation.

How it works:

Molecular vibrations:

When infrared photons hit a water molecule, they can be absorbed if their energy matches the energy required to excite a vibrational mode (like bending or stretching) within the molecule.

Absorption spectrum:

Each molecule has a unique absorption spectrum, which shows which wavelengths of infrared radiation it readily absorbs.

Changes in molecular interactions:

Factors like temperature, pressure, and salinity can alter the interactions between water molecules, causing shifts in the absorption spectrum.

Important considerations:

Water is a strong absorber of infrared radiation:

Most infrared radiation is absorbed within the top few centimeters of the water column.

Wavelength dependence:

Different wavelengths of infrared radiation penetrate to varying depths in water, with longer wavelengths being absorbed closer to the surface.

(Thank you Mr. AI dood). Always remember that AI can be political, and that the use of current textbook knowledge is habitual with Mr. AI dood.

Which makes its exhaustive analysis a few bits or so behind.

A closer consideration using more modern speak and at the same time realizing that quantum physics is cloud-bound (The Standard Model of particle physics is wrong on multiple counts) mandates that we loose the grandioseness to get down to "the brass tacks".

That would be The Photon in the context of The Thermodynamic Equation of Seawater (TEOS-10).

After all, it was Albert Einstein who indicated that the TEOS-10 version is Josiah Gibbs inspired, of which Albert Einstein was quite respectful:

"Listening to Gibbs, who is perhaps the most influential historical voice in ocean thermodynamics (encapsulated in TEOS-10) would also help:

"Albert Einstein called him 'the greatest mind in American history.' Gibbs’s studies of thermodynamics and discoveries in statistical mechanics paved the way for many of Einstein’s later discoveries."

(... APSloane). Especially since "encapsulated" means:

"TEOS-10 is based on a Gibbs function formulation from which all thermodynamic properties of seawater (density, enthalpy, entropy sound speed, etc.) can be derived in a thermodynamically consistent manner."

(Thermodynamic Equation Of Seawater - 2010, emphasis added)."

(In Search Of Ocean Heat - 5). So, the next posts in this series will use the TEOS-10 C++ library to search for clues as to the conditions that would cause "ocean heat saturation" and/or the like in the worlds oceans.

Stay tuned.
