Ocean Acoustic Thermometry...

[server]

The description in the article is quite vague, but the takeaway is not:

\"Converting those travel times [ocean floor repetitive earthquake acoustic stimuli] to temperatures, Wu and his colleagues found that the eastern Indian Ocean warmed 0.044°C over the decade. The annual fluctuations matched up well with Argo measures from the same time, but the warming signal was nearly double what the Argo floats detected. The disparity suggests Argo is missing some heat, Callies says, at least for this basin over this short span of time. Some 40% of their heat measurement came from water below 2000 meters, suggesting some warming is working its way deeper into the ocean, out of Argo’s current reach.\"

0.044oC doesn\'t sound like much but it represents a phenomenally HUGE amount of energy.

Looks like the most recent comprehensive earth energy imbalance assessment is obsolete before it even hits the press.

Ah, another victim of the huge number fallacy. Of course
the numbers are huge. The *ocean* is huge. What did you
expect? 0.044 degrees is in the noise. They haven\'t
even a clue what path their acoustic waves took.

It sounds silly to me. Ocean currents, salinity changes, topography
changes, herds of shrimp, and instrument drifts could easily overwhelm
a tiny measurement like that. It gets press because it ratchets up
another measurement of Global Warming. If they had measured cooling,
the study would have never been published.

Seriously, the most glaring flaw in the report is how do they know ten year data on a brand new means of measurement?

The 0.044C is maybe not so small when you consider the huge thermal mass involved. Do you have any idea what kind of fluctuation to expect from deep ocean data?

I don\'t think they need to know the trajectory of the acoustic signal with any exactitude. They should be able to sort that out from the time of arrival. Late time of arrival signals are from deeper cooler water. Lack of significant spread in time of arrival indicates lack of significant spread of temperature gradient with depth.

I\'m pretty sure that those kinds of interference don\'t affect the deep water measurements all that much.

No,not silly at all; it\'s a tool that gives info on distant (hard-to-study)
parts of the planet (the deep ocean). All the things that \'overwhelm\' are
things it can DETECT, it\'s just that sensitive. Those are doors to new
knowledge, if you want that.

Nonsense. I could refute that argument, if it had any content.

I think I have a few more like that in a box downstairs.

Show us some of your work.
