The graphic at Fig. 1 shows five oceanographic depth levels of the ocean environment (a.k.a. pelagic zones).

I have decided to use the mean average of those 5 depth levels to display general information (On Thermal Expansion & Thermal Contraction - 38).

I have been using up to 33 WOD depths from the WOD Manual (Appendix 11, page 132).

But since there are 33 of them, it is difficult to show them all in a post.

I have tried to narrow it to 3, 7, and random depths in the past, with suitable results, however the nomenclature of oceanography depth levels gives additional clarity.

But when I came across the Fig. 1 graphic while reading in Wikipedia (link under Fig. 1 graphic), I decided that it is time to use these depth levels in posts.

That does not mean I will change the use of the standard 33 depths in the WOD manual, here, and in my SQL server.

The values for the depths shown by name in Fig. 1 will be computed using the 33 standard depth in-situ WOD measurements as follows:

Epipelagic (surface to 200 m)

0 - 10m
10m - 20m
20m - 30m
30m - 50m
50m - 75m
75m - 100m
100m - 125m
125m - 150m
150m - 200m
Mesopelagic (>200 m to 1000 m)

>200m - 250m
250m - 300m
300m - 400m
400m - 500m
500m - 600m
600m - 700m
700m - 800m
800m - 900m
900m - 1000m
Bathypelagic (>1000 m to 4000 m)

>1000m - 1100m
1100m - 1200m
1200m - 1300m
1300m - 1400m
1400m - 1500m
1500m - 1750m
1750m - 2000m
2000m - 2500m
2500m - 3000m
3000m - 3500m
3500m - 4000m
Abyssopelagic (>4000 m to 5500 m)

>4000m - 4500m
4500m - 5000m
5000m - 5500m
Hadopelagic (>5500 m)

>5500m

As you can see, it is a matter of condensing by summation the WOD depths to derive the 5 pelagic ("relating to the open sea") zone values.

One value that changed as a result of this combination is a slight increase in the percentage of thermal expansion.

Previously it was calculated to be 2.37%, however, in this new 5-depth arrangement (see graphs below) it calculated as 3.62% (4.02195 ÷ 110.855 = 0.036281178 = 3.62%).

That is only a 1.23% difference, which I attribute to the condensation from 33 to 5 depth layers, timing of rounding, and the like (I am reviewing the code).
