I. History

Dredd Blog readers may not understand the time it takes to do graphs from a .csv file using a graph generating program like SciDavis.

It can take several days.

Some of my oceanographic software generates up to about 200 .csv files which I then have to hand load one at a time into a graph generating program.

Within that program I then select columns, write labels, etc., and then export that arrangement as a graph .png file (.png format).

Those days are over because I have written software that generates the .png files too, after it makes the .csv files.

I still generate .csv files so that I can make sure that the .png files are accurate if need be.

The new style graph files are much smaller, in terms of disk space, than the previous style.

For example, one graph of the previous style was as large (disk space size) as all the graph files in today's appendix (65 graphs on one blog page).

So, I will be using graphs a lot more in the future here at Dredd Blog.

II. The Mean Average Graphs

The graphs shown on this page (Fig. 1 - Fig. 4) are the mean averages of in situ measurements from all WOD ocean layers.

Those individual layers are shown in graphs in the Appendix.

These graphs have different colored lines for each of the five different Pelagic zone depths as follows:

Red = Epipelagic
Green = Mesopelagic
Brown = Bathypelagic
Blue = Abyssopelagic
Purple = Hadopelagic

The graph shown at Fig. 5 is the atmospheric temperature, not the temperature of ocean water.


III. The Appendix

There is only one Appendix page today due to the small graph size, in terms of disk space.

The appendix contains graphs of the individual layers of the WOD data shown here on this page as mean averages.

The span of time is not as robust because all depths are not represented by in situ measurements in the WOD database.

I am still learning how to present the data, so over time the presentations will reach the degrees of coverage previously presented on Dredd Blog.
