Just as likely they analyzed the width of the growth rings. Trees in a given area will have similar high growth and low growth years. And then there are big events where growth will correspond across wider regions.

So you mean for a plank of wood, you would do some statistical analysis based on the series of the widths of the growth things and then match them with other recorded widths/deltas to try to find a match? (Yeah, it seems plausible that it would work.)

Yep. The field is called dendrochronology: https://en.wikipedia.org/wiki/Dendrochronology

I warmly recommend everyone visit the Vasa museum in Stockholm https://www.vasamuseet.se/en Its a massive warship that capsized on her maiden voyage, and was raised in 1960s and is preserved in staggeringly amazing detail and completeness. Its absolutely gobsmackingly breathtaking :)

Speaking of warmly: if you happen to visit in summer, dress more warmly than you normally would because the museum is fairly cold to better preserve the ship.

Sweden has a western side too, which is where we get all the delicious https://en.wikipedia.org/wiki/Pandalus_borealis from.

Hey, you misspelled https://en.wikipedia.org/wiki/Surstromming

:) On a serious note, every other kind of shrimp I have tasted besides "northern prawn" (Pandalus Borealis) is just meh in comparison. To clarify: the rest of the culinary world use non-tasteful shrimp as taste carriers. Meanwhile, north sea shrimp are.. the primary source of taste, here.

I think you will be surprised when you eventually taste it!

That surströmming thing is mainly a bravado thing our northern people do. It's good for headlines and machoism both, which is why it has survived, I guess.

Visited this in 2008, on my backpacking adventures through Europe. Awesome place! We went in the Fall, Stockholm was beautiful, and great weather. Nice and cool for walking.

I briefly worked for a company at this little island, Skeppsholmen [1], a while back. It's beautiful and fairly hidden/quiet, despite being in central Stockholm. There's a hostel ship you can stay at too [2], which I highly recommend if you are in Stockholm on a budget. The Museum of Modern Arts [3] is quite good too, as far as museums in Stockholm go. As well as the Vasa Museum, which people have already mention. 1:…

There's a couple museums around the Chapman, but other than those it's inconveniently located. The other hostels in old town and sodermalm are better (and less bare-bones/no-frills). It is beautiful to look at in the moonlight, though.

"We took some chronological samples in the summer and we received the results which showed that wood is oak from Sweden, and it was cut in the winter between 1612 and 1613, which is a really good, precise measure." I'm really curious about the analysis process involved here. Is C-14 dating that precise? How do they know it was oak from Sweden?

We can rule out carbon dating because oak grows for hundreds approaching thousands of years and so the carbon dates wouldn't narrow things down. When archeologists send things to be carbon dated they try to find very short-lived woods or seeds. The way you can date oak so precisely is by the comparative widths of the tree-rings. This is called dendrochronology https://en.wikipedia.org/wiki/Dendrochronology

Carbon dating measures the ratio of C14 to C12. This ratio doesn't start to change until they die, and are no longer renewing their carbon from the environment. Radiocarbon dating does provide an accurate date (although less accurate than dendro) for wooden items, and works with a wider range of samples.

That's for short lived organisms. Trees do not renew most of their carbon during their lifetime, cellular walls are created and very rarely destroyed.
