thus introduced takes a long time to percolate through the entire volume of the ocean.

The deepest parts of the ocean mix very slowly with the surface waters, and the mixing is uneven.

Other corrections must be made to account for the proportion of throughout the biosphere (reservoir effects).

Additional complications come from the burning of fossil fuels such as coal and oil, and from the above-ground nuclear tests done in the 1950s and 1960s.

In 1939, Martin Kamen and Samuel Ruben of the Radiation Laboratory at Berkeley began experiments to determine if any of the elements common in organic matter had isotopes with half-lives long enough to be of value in biomedical research.

They synthesized Libby and several collaborators proceeded to experiment with methane collected from sewage works in Baltimore, and after isotopically enriching their samples they were able to demonstrate that they contained radioactive .

Libby and James Arnold proceeded to test the radiocarbon dating theory by analyzing samples with known ages.
