The World According To Measurements - 26

The Blank Forest
I. Is This Ours?

Which "our" is it?

Rising Tides, Troubled Waters: The Future of Our Ocean

The ocean is growing like an onion, and some of the "science" is unionized onionized.

The outer skin is growing over the wounds of civilization like a fog over the marsh, and the origin of the new skin is more unknown to "our" science than the "skin" of Mars or the Moon (The World According To Measurements - 24, Hold On To Something Alright).

I use the word "fog" because the fear-based denial enveloping the minds of many of us covers up the origin of the new outer layers of sea level change emerging one after the other.

The new source of the onion layers is Antarctica, a place that doesn't seem to be wanted, and doesn't seem to be "ours."

II. Make The Data Ours

The number one cause of the spread of global warming induced climate change denial is propaganda created and promoted by the fossil fuel industry's funding of various institutions in both hidden and in open for all to see ways (EOS, AGU).

They promote fossil fuel use (The Harm Oil-Qaeda Has Done).

On their blogs they resist warnings about Humble Oil-Qaeda.

In fact, today and a few days ago the following comments of mine (made on one of their blogs) were deleted:
"The important fact finding mission, where the researchers drilled down to the grounding line, was classic. The new reality they discovered, confirming previous hypotheses (the "warmer" water is deep) is fundamental now. Using the TEOS-10 (teos-10.org) tools suggested that this was the case. But more than that, it suggests that this is the case all around the coast of Antarctica where there are grounding lines (The Ghost Plumes - 12)"
...
"Eos could help by not censoring comments. The Ghost Plumes - 12"
(From Disqus recordings of Dredd Blog comments). Meanwhile they promote fossil fuel usage (Where and How Can We Find New Sources of Oil and Gas?, Largest Ever U.S. Shale Oil Deposit Identified in Texas).

Their membership is not allowed to vote on this issue, causing some to drop their lifetime membership (see comments here, the discussion here, and the discussion here).

So, encourage your institutions of all kinds to stop it because it skews the research and does damage to what is "ours."

III. The Honest Data

Regular readers know that here on Dredd Blog the facts rule the day, not Oil-Qaeda propaganda.

So, true to fashion readers will be given data analysis free of charge, data which comes from the World Ocean Database (WOD).

It is then deciphered and converted into an SQL-server database (WOD Update).

The graphs made for today's post are supported with HTML tables containing the details in the database.

The relevant information is provided in the appendices to today's post, which features the Antarctica Ice Sheet's interaction with the ocean all along the grounding line of Antarctica's Tidewater Glaciers.

IV. General Details About The Data In The Appendices

The appendices are organized according to the melting process at the grounding lines: first comes melt conditions (ambient water containing a sufficient number of infrared photons), then comes ice melting into seawater, and finally plumes are caused by the differences in the density of the glacial melt water compared to the denser ambient seawater.

So, Appendix A&B feature data concerning melt conditions, presented in HTML tables (Appendix A) and graphs based on that HTML data (Appendix B).

The top lines show the temperatures of the seawater, while the lower lines show the temperature at which ice will melt there in those conditions.

As long as the seawater temperature is above the temperature at which the Tidewater Glacier's ice will melt, there will be plumes.

The graph lines are color coded as to depth and temperature (a legend on each graph explains that).

The glacial ice melt dynamics concept is likewise presented in two appendices (C&D).

One is in the format of HTML tables (Appendix C), and the other is in the format of graphs (Appendix D).

Finally, the plume flow dynamics concept is presented in the same two formats, HTML (Appendix E) and graphs (Appendix F).

NOTE: the glacial ice and plume flow quantities are estimates.

Currently the distribution between above sea level basal melt (on land) and calving, compared to below sea level (under water along and above the grounding line) is 32% (above) / 68% (below).

This ratio is only an estimate because we do not know exactly, but it is being made more accurate as time goes on (the total ice mass loss for Antarctica, i.e. both above and below sea level, is detailed here).

The temperatures in the sea water data presentations are made from actual in situ measurements downloaded from the WOD database, then averaged.

The temperatures at which ice will melt are calculated with the TEOS-10 toolbox, using the actual in situ measurements just mentioned.

V. Closing Comments

When added up the subtotals don't always match the totals for some areas because the graphing software requires some "smoothing."

That is, there are gaps in the in situ measurement record, so when data gaps take place, and when possible, the gaps are filled in by the software (by averaging the closest numbers to the gaps).

The bottom line is that the trend of the disintegration of the Antarctic Ice Sheet is not an estimate, but how fast the degeneration will accelerate is an estimate.

The trend is crystal clear.

The ice sheet disintegration into seawater has increased about six-fold over the time span shown in the appendices (detailed by glaciologists here).
