Wiki carbon 14 dating

From this limited amount of information, and through assumptions about the accumulation history (sedimentation rate, hiatuses), the ages of all depths of a core need to be estimated somehow (age-depth modelling).

C atom will disappear cannot be predicted; it could happen within a few seconds, but it could also survive several tens of thousands of years.

Sometimes the age-depth model is extrapolated beyond the dated levels; extrapolated ages should be treated with much caution, as should core sections with low dating resolution.

We are also working on ways to estimate the age uncertainties for the cores (e.g.

— It was while working in the Kent Laboratory building in the 1940s that researchers developed radiocarbon dating—an innovative method to measure the age of organic materials. — The Earth's magnetic field experiences reversals such that north becomes south. Researchers have dated volcanic ash that was formed immediately before ...

The settings of the site could help in deciding about which model to use; sites which can be assumed to have accumulated in a relatively stable manner over the studied period, could for example be modelled using linear regression, while sites with many likely changes in sedimentation rate (e.g.

sites which changed from a lake to a mire) could perhaps be better modelled using linear interpolation between the dated levels.

Indeed, it is recommended to check how different modelling assumptions would impact the age-depth models of individual sites.
