SuessR: Regional corrections for the effects of anthropogenic CO 2 on δ 13 C data from marine organisms
Abstract Anthropogenic CO 2 emissions associated with fossil fuel combustion have caused declines in baseline oceanic δ 13 C values. This phenomenon, called the Suess effect, can confound comparisons of marine δ 13 C data from different years. The Suess effect can be corrected for mathematically; ho...
