A large collection of radiocarbon dates, collected from shells incorporated into the glacial advance diamicts and postglacial sediments, indicate the ice sheet advanced later than 24,000 years ago, and had retreated by 13,700 years ago. 2/5
This is the first study that vertical mixing could already be suppressed in the oceans by stratification: "Changes in Oceanic Radiocarbon and CFCs Since the 1990s"; agupubs.onlinelibrary.wiley.com/doi/10.1029/... - good thing: via vertical mixing across density layers only about 20% of OHU happens
Recent trends in upper ocean Δ14C, pCFC-11, and pCFC-12 are negative, reflecting their decreasing atmospheric trends Increases in ∆14C are only observed in a few places over 2000–2010s, showing o...
I’ve seen a lot of people say this but it bears repeated that there is nothing quite like the litttle feeling of joy and anticipation when you get your radiocarbon date back.
There is great potential for language analysis to be brought into conversation with other methods, from ancient DNA analysis to sediment core analysis, to radiocarbon dating of archaeological materials.
Me reading about radiocarbon dating during my degree: BORING Me reading about it for my passion project: this is so unbelievably cool why did I not appreciate it earlier?
My understanding is that it’s radiocarbon dating but I have no idea how that’s done with bog butter specifically!
Now one of my go to stories about 'why you have to rewrite history' This was not genetics, radiocarbon and isotope dating, linguistic analysis, new digging stuff up, or new insights by bringing new perspectives and social attitudes. This was some dude with a horse checking the stones
Curated character of the Initial Upper Palaeolithic lithic artefact assemblages in Bacho Kiro Cave (Bulgaria) 🏺🧪 Tsenka Tsanova, JJ Hublin et al journals.plos.org/plosone/arti... Newly excavated lithic assemblages are dated by radiocarbon between 45,040 and 43,280 cal BP
