Radiocarbon dating has long been used to reveal the age of organic materials — from ancient bones to wooden artefacts. Scientists are now using the amassed dates for wider applications, such as spotting patterns in human migration. And a Canadian database is poised to help researchers around the world to organize this trove of archaeological and palaeontological data, and to address problems that have plagued carbon dating for years.
The database currently holds 70, radiocarbon records from 70 countries. The latest effort aims to make the software behind the site open source, making it easier for other research groups to set up their own version of CARD while still contributing core information to the main database.

The first such site should come online within the year. Researchers need to consider a carbon dating science journal of factors during their analysesincluding the type of material tested and variations in the rate at which the organic matter incorporated different carbon isotopes, in order to produce an accurate age.
A global database would ensure that this kind of information accompanies every data point, so that if dates have to be recalculated in the future, they can be, he says.
A centralized database would https://masterlovesearch.today/term1/d1281.php make it easier to find previously published radiocarbon data. But the most compelling reason for a single large data set, says Kelly, is that it enables data mining. Given enough properly dated archaeological finds, some experts argue that they can start to make careful population estimates and trace how human populations moved over space and time.

Martindale plans to mine the data to confirm and quantify North American population changes due to wars or settlement relocations that are currently known only through indigenous traditional storytelling. Some information, such as precise site locations, must be kept secret in some countries to avoid looting.

And metadata, including the context of an archaeological find or the exact testing methodology, are hard to standardize. Funding is also an issue. To sidestep the problem, he will make the CARD software open source, so that other groups can create clones of the site tailored to their needs.
The core data can then be sucked into the CARD database. They hope to have something up and running within the next year, says Carley Crann, a lab technician at AMS who is heading the effort.
