It is known that such variations have occurred, but it is thought they can be corrected for by comparing a sample’s C level with the standard curve constructed using samples of known age.Carbon-14 dating depends on the amount of atmospheric carbon-14 relative to carbon-12. This ratio would have been different before the Flood. According to these authors, the total mobile (non-carbonate) carbon in the biosphere is about 40,000-45,000 gigatons. The global carbon cycle: a test of our knowledge of Earth as a system. If these three conditions are met, the initial concentration of C in the sample can be estimated.
In practice, there are sufficient variations in these conditions that it is necessary to correct a sample’s raw radiocarbon age by comparing it with the standard calibration curve.
Violations of this assumption occur in the ocean reservoir due to the time required for mixing of surface waters with the deep layers.
