Radiocarbon dating calibration oxcal

This is especially true when comparing samples from terrestrial organisms and those that assimilated radiocarbon from the marine environment.

Even if the organisms have the same age, they wouldn’t have the same carbon 14 content and would thus appear to be of different radiocarbon age. Surfaces of oceans and other bodies of water have two sources of radiocarbon – atmospheric carbon dioxide and the deep ocean.

BCal is a related service, but it also doesn't have an obvious API.

This lack of an API for both of these may mean they are dead ends for an R package, but perhaps you can see something I can't?

Deep waters in oceans get carbon 14 from mixing with the surface waters as well as from the radioactive decay already occurring at their levels.

Studies show that equilibration of carbon dioxide (with carbon 14) in surface water is of the order of 10 years.

Bacon and clam might be the best bet here, since they're already R-based, packaging them would be more straightforward than the other two.

The static data is the calibration curve, you input raw radiocarbon measurements and other related variables and the software computes the intersect with the calibration curve and returns calibrated dates.

These carbon 14 atoms then instantaneously react with oxygen present in the atmosphere to form carbon dioxide.

The assumptions, however, do not paint the real picture.

There are several factors that need to be considered because they affect the global concentration of carbon 14 and therefore that of any given sample for radiocarbon dating.

However, carbon 14 content is not the same at the surface mixing layers and that in the deep ocean; hence, not all marine organisms have the same radiocarbon content.

There are many factors to consider when measuring the radiocarbon content of a given sample, one of which is the radiocarbon content of the plant or animal source when it was alive and its local environment.

Do you think I should email clam and/or bacon folks?
