Fig. 1 Greenland Subsurface Temperatures
The waters around Greenland dramatically show the changing temperatures I have been writing about lately (Fig. 1).

The contrast from area to area is shown by the contrast in temperature volatility between Fig. 3 and Fig. 1.

The map at Fig. 2 shows the WOD Zones where the data used to generate the two graphs originated.

In Fig. 1 it appears as though the layers are moving up and down, mixing or crossing paths, as well as being impacted by external influences.

Some of it is caused by the dynamic of both colder and warmer waters that are flowing in from elsewhere.

That "elsewhere" is well known surface and subsurface currents (The Question Is: How Much Acceleration Is Involved In SLR? - 4).

Fig. 2  WOD Zones - Greenland & Australia
Other phenomena may also play a part in the strange temperature behaviors there.

At any rate, the less volatile water temperatures at various depths around Australia may have misled the scientist who wrote the scientific paper I criticized recently (The Warming Science Commentariat - 8).

On another subject, as you can see, the module that processes a list of zones is a handy tool.

Fig. 3 Australia Subsurface Temperatures
As in the case of Fig. 1 and Fig. 3, I can make a list of any WOD zones and it will generate the CSV files with which to graph the subsurface ocean temperatures that have been measured and recorded over the years.

IMO that is a better way to deal scientifically with subsurface temperatures and other features, since the same module will do that for the many other ocean-content measurements in the World Ocean Database (WOD Depth Dependent Variables).

Surely, those scientists will not repeat the folly and urge is to believe that mathematical formulas are a way of detecting a host of temperatures and chemicals found at various depths?

If a researcher has to go to those depths with submersibles anyway, why not gather all the data while there, rather than speculating with mathematical guesswork?

  1. Good stuff Dredd!
    Many thanks!

    Article showing the relationship of many places to Greenland / Antarctic melting but Florida looks to be the first one 'in' for a swim. And, the attendant issues (beyond just water rising)are enormous.
    "These pulses, which have caused as much as thirty feet of sea level rise per century in the recent geologic past, are tied to periods of “rapid ice sheet disintegration” on Greenland and Antarctica."
