Tree-ring (dendrochronology) study from Finland

Hello,

I'm currently interested in measurements and chemical markers found in various natural samples (ice cores, tree rings, peat bogs, and others).

I've managed to complete the first steps:
  • finding data
  • compiling the data into a CSV file
  • importing it into a plotting software (plotting/charts)
This is fascinating!

A potential goal is to be able to identify comet impacts and distinguish them from other events—for example, volcanic eruptions, tsunamis, and others—by analyzing the plots. There's no word "comet", on plots... just peaks, highs, and lows... and very diverse databases. Comets do leave a signature, but I'm not an expert in this area, yet!

I admire the work of Mike Baillie, a tree-ring specialist. With a little searching, I came across some of his measurements, and also a Finnish study—the results of which I'd like to show, through the creation of a plot.

I'm aware that climate data of this kind has its imperfections, and several pros and cons have been raised. From experience, it's possible to use this data as a starting point. Thanks to the Cassiopaean data, we have solid dates and reference points. Reading the graphs becomes very interesting, even if there are sometimes visual discrepancies. We can find correlations and many studies are possible.

Here, then, is a typical study on tree rings:


"Finnish over 7500-yr pine chronology"

DATA page: https://lustialab.com/data/Advance/Info_Advance10K_basic.pdf found on https://lustialab.com/Lustia/download.htm
There are two sets of data: "The 5520 BC chronology" and "The 5634 BC chronology"

GENERAL PRESENTATION: https://www.researchgate.net/public...pine_tree-ring_chronology_for_Finnish_Lapland


You will find attached one plot in two different resolutions (200dpi, 300dpi) - I cannot display the 300dpi normally on my computer, but could be that you can. I used the software "labplot".

I will try to include the 300dpi plot here below:
labplot - 5634 BC serie - 300dpi.png


Seems it's displaying, so finger's crossed that it stays visible after I post the message!

The dataset is "Master dating series", from "The 5634 BC chronology", found in the document "Cofecha output: Quality and dating control", present on the DATA page:
https://lustialab.com/data/Advance/adv7638coc.pdf

If anybody would like to reproduce the plot, I attach the dataset too.

I hope that you will enjoy it! The plot shows various events that the forum is familiar with. Caesar, The Black Death - we can clearly see some variations in the peaks at various periods.

Let me know about anything that which comes to mind!
 
I am not sure whether you read some of recommended books where some of these authors did similar type of analysis. If not, you may want to read them.

Mike Baillie is Dendrochronologist. He uses that data.

Laura and team also did Historical data project. Team read many books and pulled out observations ( portents, earth changes etc.) from many ancient writers. The site is no longer up. Here is the dump of the data from HTML. This dump doesn't have source info ( authors, book name, chapters etc.).

Hello,

Thanks a lot for the links! The QFG doc looks really great! Wouldn't you build a clone of it, with your C data exclusively? Would be great! That's if there is time^^

I was thinking that it would be interesting than to have a section dedicated to plots and climate data such as ice cores and tree rings - but this may be subjective. Could be that one day, a person would like to either research the topic - in this case the data is steady (it's sometimes a bit time consuming than to search for datasets and references, theory about "which chemical marker does what", too) - either find a chart illustrating an article, an idea (or else). It would work great, IMO, than to have a dedicated forum, with a sub-forum "plots & data" (something like that) and another one for the theory ("chemical markers", "softwares", etc). Both types of data would not be immersed into one big whole. You could add some plots to your C doc, to illustrate all the events scattered on the timeline. "Here, we see well the ... and ...". Just an idea!

Yes, the Napier name has been a recurring one in Laura's articles and many topics here. My perception of his work and other's were kind of sunk into big articles, so that it was hard to really consider the richness and the application of the ice core & tree ring (for example) research. Napier & plots are always around - but it's only today, after versing myself into the science itself - that it makes much sense. I could have been wandering for several additional years, if I did not have the idea of creating a plot. Usually, "we see a plot", "on an article" - and we would (for example!) focus on "the spike" ("yeah there's a spike the author is right") and would keep on reading. But the plot itself is a real story teller in itself, a whole dimension added, I believe.

Thanks for the references (and the various ones that, with kindness, you already provided me in your great cosmology thread - sorry if I expanded too much on other topics, inside, I will keep cautious in the future) :-)
