WUWT readers may recall last week that we had an excellent guest analysis by Bob Tisdale titled:
Ocean Heat Content: Dropping again
Easy come, easy go. The data has been changed. Read on – Anthony
NODC’s CORRECTION TO OHC (0-700m) DATA
Guest Post by Bob Tisdale
I was advised today (Thanks, Fred) that the NODC has revised their Ocean Heat Content data. A quick check of the KNMI Climate Explorer News webpage…
http://climexp.knmi.nl/news.cgi?someone@somewhere
…reveals that it was revised on October 15, 2009 at KNMI.
And a check of the NODC data…
…shows that it was corrected on 10/15/09.
Dr. Geert Jan van Oldenborgh writes, “There was an error in the last 3-month data point of the NODC ocean heat content dataset, as anyone who made a map of the data could see. The problem has been fixed at NODC (thanks Gavin, Tim).”
Apparently the NODC hadn’t bothered to plot the data prior to posting it on September 14, 2009, or hadn’t thought there was a problem until…
Here’s a gif of the correction

NODC CORRECTION
Thanks, Gavin and Tim.
Hmm, I’ll have to go back and update the “ENSO Dominates NODC Ocean Heat Content (0-700 Meters) Data” post to make sure the ENSO-induced step changes are still there and verify the “North Atlantic Ocean Heat Content (0-700 Meters) Is Governed By Natural Variables” hasn’t changed, too.
H/T to Fred.

UPDATE (October 15 @ 5:40PM):
After I posted the above, I found that Dr. Geert Jan van Oldenborgh had emailed me to notify me of the correction. I have received his permission to reproduce his email:
Dear Bob Tisdale,
please note that NODC discovered that they had accidentally posted the wrong version of their last file (apr-jun2009), a preliminary version with most data still missing had somehow made it to their web site. A quick look at the map for that quarter showed that there were hardly any anomalies visible and big anomalies in the North Atlantic and Pacific did not persist from the previous quarter, so the data were clearly suspicious. This mix-up has been fixed tonight (Dutch time) at NODC and in the Climate Explorer. A corrected version of the average heat content is attached, the value of apr-jun2009 is now more in line with the values of previous quarters.
Greetings from chilly Holland,

My, how convenient.
There’s been a lot ‘data issues’ as of late.
They must be slippery little rascals considering how frequently they elude the posted data sets.
Although such a sudden drop is likely the sign of an error someone I find it interesting that no one at the NODC has questioned the similarily odd jump in 2003. Has anyone bothered to ask them why?
“Data Issues”must be a subspecies of Gremlins-always able to cover for bad math or engineering mistakes…
Or faulty Satellite sensors….
This is beginning to smell like last Friday’s fish…
-Not Refrigerated of course…
Still not warming….
I really appreciated the post with updated heat content graphs by Bob T, but I was expecting a revision, as the sudden down spike in heat content at the end of the series looked suspicious to me.
Anyone find it suspicious that all corrections to temps. and now OHC seem to move reported anomalies or amounts upward?
It’s very rare or not at all to see a correction downward, unless it’s more than a few decades back.
Even though the science is settled, political science sucks.
Raven (16:25:37) :
That jump was warming & therefore must be correct /sarc
DaveE.
I’m convinced that NONE of this data on Global Warming is valid.
I don’t believe that we are any warmer today than we’ve been in the past
I don’t believe that the arctic is anymore ice free today than it has been in the past
I don’t believe the arctic temperature posted on the side of this page.
I dang sure don’t believe that the ocean temp is as high as they are reporting, and will continue to go up up and away.
I don’t believe that what passes for sunspots today was remotely what was condsidered a sun spot 100 years ago ..[I mean .. I see one .. they see 20 .. go figure].
I don’t believe any of this crap!!!
I think the time has come that Science is outsmarting itself!!!
It’s weird that all these data issues lately support the hoax. I am sure it’s just random. And nothing to don with the hoaxers bill coming up.
Yet the weather outside looks white …
Well that’s not good news, coupled with the recent slight uptick in sea levels,
http://sealevel.colorado.edu/current/sl_noib_ns_global.txt
I though that the record low solar cycle 24 was finally effecting things…
Soon we can expect new graphs like those shown here…
http://www.edf.org/documents/5544_SolarActivity_One-pager.pdf
shown with the solar activity vs temperature curves completely diverging… the solar cycle curve diving with the temperature curve staying constant (or going back up based on recent satalite data) …. it’s going to get very difficult to justify a solar link.
Wonder how long the lag is?
I’m still suspicious of that 2003/2004 jump in OHC from when the good Argo data begins. The previous data is questionable to say the least and It looks like a splicing error.
There is still no warming in the Argo data despite the confident predictions of Hansen and the climate models.
Good post by Tamino on the subject despite the fact he confidently asserts OHC is increasing and will increase.
http://tamino.wordpress.com/2007/01/18/ocean-heat-content/
I’m assuming that this is the right data now.
At least we can assume that they double-checked the numbers and now we can officially extend the period of no 0-700M warming in the ocean from 2003 to 2009.5
I’ve been watching the AGW story for quite a while and it always surprises me how the spotting and correcting of errors seem to only ever go in one direction. If it ‘warms’ well that to be expected right? If it cools … ooo, better investigate and figure out what went wrong.

“Even though the science is settled, political science sucks.”
Political Science — now there’s an oxymoron if I ever saw one.
We are getting a nor’easter here in PA, projected to drop a foot of snow in some places, to be followed by another snowstorm this weekend. If those adjusters could come and adjust the real weather it would be appreciated. A foot of snow let’s just statistically adjust it to a more reasonable dusting. I mean it never snows in PA in October, it is obviously an error in the data.
Sideshow Bob;
“it’s going to get very difficult to justify a solar link.”
It is going to be very difficult to justify ANY link!!!!
Air temp flat.
Ocean temp flat.
Ocean Heat Content flat.
Arctic recovering.
Antarctic flat (and really big).
Greenland recovering.
CO2 going up steadily.
Sun tiny signs of awakening.
Seems like no correlation is holding its own!!!! Of course, with bad data that is to be expected!!
Deanster (16:46:34) :
Sorry mate but you’re probably wrong. The World has certainly warmed over the last 30 years! Personally, I’m not so sure it’s any warmer than the previous warm spell in the 30s but that’s just my view.
What a lot of people miss is that the warming is in Winter. The LIA Summers were often as warm as now but the Winters were brutal and longer! Then the Winters warmed, then cooled, then warmed then cooled, then warmed again.
This however is one of the fatal flaws in the AGW process. We won’t fry because it’s not the Summers that are changing, it’s the Winters.
DaveE.
Political Science — now there’s an oxymoron if I ever saw one.
It’s a Marxist term. Scientific socialism and all that {insert your preferred word}.
Up, up and away in my beautiful hot air balloon.
So, now that it’s still not getting warmer, the oceans are just as warm as ever, and the sun is still as quiet as it has been for 3 years, what now?
Didn’t these oceans just flip cold? Or, did the data just flip over and play dead?
Sensor problems, again?
Oh, I have it. Yes, that’s it.
It’s CGR Climate Forcing. They warm the waters but cool the land.
Watch out for big snows.
It’s also getting obvious to me that Unisys is not in total support of the AGW agenda, SST’s on their map are still going down from the recent high.
http://weather.unisys.com/surface/sst_anom.html
Their data is showing the oceans noticably cooler than what NOAA’s data shows.
Also note the graph I saw on the last thread on OHC that sometimes it almost looks as if SST’s lag OHC or OHC lags SST’s, it’s not clear which leads which if you look at the whole thing.
I’m trying to understand how such errors are sliding through unnoticed. Surely there is some sort of criteria to prevent this sort of thing. Beginning to think the whole world has gone mad and is trying to create mass hysteria.
I would agree that any data coming from employed gov’t workers is sceptical at best. People are afraid for their jobs and since the powers that be want AGW to be true, the scientists employed have every incentive to falsefy data. It’s their job that’s on the line.
How many people have said “if you don’t believe in man made global warming you should have your scientific credentials removed”? Many.
The fact of the matter is 20 billion dollars have been spent on a theory that man’s production of CO2 into the atmosphere is greater than the earths ability to absorb it. What arrogance! 3/4 of the earth is water, and deep at that. To date no correlation has been made to rising CO2 levels and rising temps.
It doesnh’t take a scientist to know the earth is cooling. Look outside.
Snow in South Africa, SAudi Arabia, Malibu, Houston?
The sun has gone quiet and all that warmth we received from the active sun during the 20th century will be a well missed event.
What bothers me the most of all this AGW talk is no one is preparing the country, or it’s people, for a prolonged period of crushing cold temps and the shortened gowing seasons that are sure to follow. We are wasting time and money on an idea that has been proven false.
How many people will have to starve to death before people wake up to reality?

Heh! I actually first read the line as “here’s the gift of the correction”. 🙂
