Deuterium, as O18, are stable isotopes of H and O, respectively.
As the temperature of the oceans heats up, more of the heavier water (with a D instead of an H, or an O18 instead of an O16) are evaporated. So, the precise measurement of D and O18 in Mud Core or Ice Core DATA, provides a very good measurement of past temperatures. The Mud Core peopled had this figured out over a half century ago -- the latter Ice Core people used this science that the Mud Core people had developed.
And my hat off to you for having called BS on the climate narrative a long time ago --
I was a BELIEVER for so long ... it took me more than a decade to transition to a skeptic, and then a denier!
I'll see what I can dig up in 4hrs (that's all I got mate- I'm one of the "actually does work" crew😉
Query, I'm familiar with deuterium as an isotope used in nuclear science and physics, but not heard it being used to timeline in climate science, but as a farmer, I called BS on the climate narratives long ago, so haven't paid much attention to climate sci since😉
Another link I have, which not be so good, has these data reformatted into 100 year increments, and therefore the DATA are not raw, but massaged in some way:
Tim, I’m confused. You say you have the Vostok Ice Core Data in 100 year increments and used it to complete your analyses with links to results. Then you say you don’t have the data and seek a link. What am I missing?
First Link: only 235 rows of Data -- Data goes back 400 kyrs, more than 1 kyr between data points. We are looking for a file with at least 8000 rows of DATA to provide DATA every 100 years for 800,000 years.
Second Link: 283 rows of DATA spanning 414000 years -- want a file with at least 4000 rows of DATA for this partial (half) the available record.
Third Link: I couldn't find it, maybe it's there someplace. Did find a 4,000 line record:
Thanks Thomas !
Well, more than one thing can be true at the same time!
While these data reside on my hard disk, and backed up,
I also cannot find any place on the Inter-Web to download and verify these DATA.
I'll bet there's many live links to these DATA --
Just no "Google-Findable" links.
Wow !
You guys are giving me lots of Homework to do !
I'll try to plow through all those links today --
If not,
I have a very big wolf whom I can claim ate my homework.
So far I don't think we have a winner !
So Folks --
How can anyone verify, or disprove, my simple calculations, if no one has access to the DATA?
Rather than offering a reward for the DATA, I should be selling it!
Of course, in principle, I could only sell it once, and then it would be out in the Wild.
I probably could have just been bold and offered 1000 or 10,000 $.

Can you illuminate a bit more?
Let me just add a few comments here for now -- I'm quite busy now on other things but will write a follow-up to this post B4 the end of April.
I've found two links with the complete 800 kyr record:
https://www.ncei.noaa.gov/pub/data/paleo/icecore/antarctica/epica_domec/edc3deuttemp2007-noaa.txt
Another link I have, which not be so good, has these data reformatted into 100 year increments, and therefore the DATA are not raw, but massaged in some way:
http://www.climatedata.info/proxies/data-downloads/
Is this Vostok Ice Core data useful?
The time period coverage is from 253,000 to 75,000 in calendar years before present (BP).
https://www.ncei.noaa.gov/access/metadata/landing-page/bin/iso?id=noaa-icecore-2443
Contains only 3 of about the last 10 Ice Ages.
Data for Depth/Time and CO2, but no T or D.
Tim, I’m confused. You say you have the Vostok Ice Core Data in 100 year increments and used it to complete your analyses with links to results. Then you say you don’t have the data and seek a link. What am I missing?

Hi Tim,
Maybe you find something in here:
https://cmr.earthdata.nasa.gov/search/concepts/C2532071350-AMD_USAPDC.html
https://iridl.ldeo.columbia.edu/SOURCES/.ICE/.CORE/.VOSTOK/index.html
https://www.ncei.noaa.gov/access/metadata/landing-page/bin/iso?id=noaa-icecore-2443
First link just leads to a .pdf describing DATA.
Second link, couldn't find much of the DATA.
Third Link: Only CO2 Data
Deuterium in Vostock Ice Core for 420,000 years
https://doi.pangaea.de/10.1594/PANGAEA.55505
As with Dave Hawkins Data, only Time, Temp and D -- no CO2.
And, yes, could combine these Data with your previous link and have Time, Temp, and CO2 for less than 200 kyrs out of 800 kyrs.
But that's better than nothing.
Have you tried your dead link from 5 years ago using the Wayback Machine:
https://web.archive.org/
Didn't the way back repository get wiped recently?
Hi Tim.
There's a set of EPICA data that claims to stretch to 800k years while I saw mention of Vostok only going back about 450ky
However, not sure that the EPICA dataset includes all that you asked for.
The EPICA data is at:
https://doi.pangaea.de/10.1594/PANGAEA.683655
Best regards (and apologies if this is a false horizon)
David
Nice DATA set --
Contains depth, age, delta D, and delta T.
No CO2 Data.
How could one use this to show, e.g., that CO2 Lags Temp ?
So, incomplete.
Am I supposed to give Partial Credit?
There's CO2 data at below link but maybe this needs 'binding' with earlier dataset and not sure what's meant by "revised composite" values

two datasets on one graph...
http://rpubs.com/DavidHawkins/1284454
Wow Dave --
Think we have a WINNER!
Looked at your rpubs and those are definitely the DATA.
Can you please provide two links -- links for people to download the dT and CO2 DATA that you show on your rpubs ?
Hi Tim
Apologies was in the Rpubs comments but just realised they’re only visible to the author
Sources:
CO2 data: https://www.ncei.noaa.gov/access/paleo-search/study/17975#:~:text=The%20European%20Project%20for%20Ice,quality%20data%20in%20other%20sections.
Delta Temperature: https://doi.pangaea.de/10.1594/PANGAEA.683655
Exactly WHICH link on that page of many links for the CO2 DATA.
Oh well, no prizes for second but enjoyed the chase. Will keep looking (after checking if others have found the correct dataset)
