Radiocarbon formed in the atmosphere is dissolved in oceans in the form of carbon dioxide and contemporaneously assimilated by plants through photosynthesis and enters food chains.

This is how terrestrial organisms take in carbon 14 in their systems.

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.

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

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.

It is used in dating things such as bone, cloth, wood and plant fibers that were created in the relatively recent past by human activities.

The database is also intended for use with radiocarbon calibration programs such as CALIB (Stuiver and Reimer, 1993) or Ox Cal (Bronk Ramsey 1995) using the 2013 marine calibration dataset.

Samples from marine organisms like shells, whales, and seals appear much older.

Another factor to consider is that the magnitude of the marine reservoir effect is not the same in all locations.

Radiocarbon dates of a terrestrial and marine organism of equivalent age have a difference of about 400 radiocarbon years.

Terrestrial organisms like trees primarily get carbon 14 from atmospheric carbon dioxide but marine organisms do not.
