Hi to all and happy new year!
While searching the web for roman pines chronologies (impossible!), I quickly retrieved an oak chronology from Crummy P., Hillam J., Crossan C. 1982, Mersea Island: the Anglo-Saxon causeway, in Essex Archaeology and History, 14, pp. 77-86 (http://cat.essex.ac.uk/reports/EAS-report-0023.pdf).
Since the forum does not allow me to attach files, I copy and paste it below as text.
The table on page 85 has a .crn similar fashion, and I just (semi-automatically) adapted it in a text editor. It contains indices (three samples from two stems) of a somewhat famous chronology from Mersea Island, that is quoted and partially published several times (see, for example, Hillam J. 1981, An English tree ring chronology, in Medieval Archaeology 25, pp. 31-44 - http://ads.ahds.ac.uk/catalogue/adsdata ... 31_044.pdf ) but this is the only case in which it is complete.
Probably Lars Ake already included it in some of English collections during his work about Oak European chronology (http://www.cybis.se/belfast/index.php) but I don’t remember seeing it as “individual series”. Anyway, if I missed it, please forgive this post.
Some other late roman/early medieval chronologies are published too in the two paper quoted above, as ring width measurements diagrams, but they are incomplete.
Best regards,
Ale

Re: Mersea chronology (AD 445-661) - England
Hello Alessandro!While searching the web for roman pines chronologies (impossible!), I quickly retrieved an oak chronology from Crummy P., Hillam J., Crossan C. 1982, Mersea Island: the Anglo-Saxon causeway, in Essex Archaeology and History, 14, pp. 77-86 (http://cat.essex.ac.uk/reports/EAS-report-0023.pdf).
Since the forum does not allow me to attach files, I copy and paste it below as text.
As your editing efforts were distorted by the forum.... - I reedited it and put the file here:http://www.cybis.se/wikidata/mersea.crn
Yes, it is part of the member EastAnglia1 contained within the collection EnglishMaster which can be found here:
http://www.cybis.se/forfun/dendro/hollstein/ - see the section "The Belfast data" and "Files to download" where there is an EnglishMasters.zip file
By the way... it is Petra who has done the most work on synchronizing the Belfast and the English data!
If you need the original English data, you can probably get it from Cathy Tyers if you ask her! If it is OK for Cathy you can also get our synchronized versions, though they stand for our current interpretation of the data and there is no guarantee for its correctness.
It is a bit thought-provoking to read Hillam's sentence written in 1982 (it is under the tree ring index table): "In time, it should be possible to find a link between these Saxon curves and the floating Roman chronologies and so obtain a complete English tree-ring curve for the last 2000 years."
Still we are not able to give a solution and bridge the gap between Roman time and later times. Today we have two quite different solutions and no replication from within another region. German dendrochronologists allege that they have bridged it, but they prefer to keep their data secret as one of them put it: our research on how a correct bridging should be done "is not meaningful".
