In the previous posts in this series the number of measurements of ocean temperatures at a few locations were featured.
In this post the appendix contains many more locations and many more counts.
For example, only portions of the Atlantic and Pacific oceans were featured in the previous post; and in the first post of this series the "layers" used included a mixture of many segments of oceans because it was done on a latitude basis (a latitude based layer circles the globe and includes segments of several oceans).
There is nothing wrong with looking at it that way, but the more ways in which we consider these things the more likely we are to discover something useful.
In today's post and appendix the relevant WOD Zones (Fig. 1) are specified for each area of the ocean that is featured in terms of the number of measurements made in that ocean area.
The data featured begins in the year 1900 and continues until the year 2023.
The emphasis is to show that the deepest layer, the Hadopelagic depth, is not well represented in our history of ocean measuring records.
But more than that, we can also see how the ups and downs of measurement research based on ocean temperature taking significantly varies over time.
So, in the Appendix GR2 the measurements in the following WOD Zones in the listed ocean areas were counted:

Note that some ocean areas such as smaller "seas" and the like do not have enough measurement data to make graphs without a pretzel effect, so several of them are grouped together then used to acquire enough measurements to make meaningful graphs.
The following miscellaneous ("Misc") groups were composed of the zones listed in each one.
All of the above oceans as well as the following miscellaneous ones are graphed in the Appendix GR2:
Misc_1:

The graph at Fig. 2 shows the patterns when all WOD measurements in my SQL database are used (notice the drop in measurements during world wars; your guess is as good as mine as to what caused the drop circa the year 2000).
I hope you find the records of ocean temperature taking, presented in this series as mean averages to be as interesting as I do.
I use over 5 billion measurements from WOD, then condense them from WOD depths to pelagic depths, then into mean averages, so the "counts" values presented are still representative of the whole shebang.
The previous post in this series is here.
