Specifically, volcanic carbon dioxide is known to depress the carbon-14 level of nearby vegetation, and dissolved limestone carbonate occasionally has a similar effect on freshwater mollusks, as does upwelling of deep ocean water on marine mollusks.

There may come a time when all radiocarbon ages rest on firmer knowledge of the sample’s original carbon-14 level than is now available.

In addition to spatial variations of the carbon-14 level, the question of temporal variation has received much study.
