Application of carbon 14 dating
The World Ocean Circulation Experiment (WOCE) The World Ocean Circulation Experiment (WOCE); at the Woods Hole Oceanographic Institution's NOSAMS Facility.
Measuring carbon in the Pacific and Indian Ocean to understand better the processes of ocean circulation.
Because organisms stop taking in carbon-14 at death, the age of the material can be precisely determined by this ratio of carbon isotopes.
According to Stuiver and Polach (1977), all laboratories should report their results either directly related to NBS Oxalic acid or indirectly using a sub-standard which is related to it.
It is vital for a radiocarbon laboratory to know the contribution to routine sample activity of non-sample radioactivity.
This is the International Radiocarbon Dating Standard.
The Oxalic acid standard was made from a crop of 1955 sugar beet. The isotopic ratio of HOx I is -19.3 per mille with respect to (wrt) the PBD standard belemnite (Mann, 1983). T designation SRM 4990 C) was made from a crop of 1977 French beet molasses.
Carbon-14 dating is a way of determining the age of certain archeological artifacts of a biological origin up to about 50,000 years old.
