Models describing the evolution of the partial pressure of
atmospheric oxygen over Phanerozoic time are constrained by the mass
balances required between the inputs and outputs of carbon and sulfur
to the oceans. This constraint has limited the applicability of
proposed negative feedback mechanisms for maintaining levels of
atmospheric O2 at biologically permissable levels. Here we describe a modeling approach that incorporates O2-dependent
carbon and sulfur isotope fractionation using data obtained from
laboratory experiments on carbon-13 discrimination by vascular land
plants and marine plankton. The model allows us to calculate a
Phanerozoic O2 history that agrees with independent models
and with biological and physical constraints and supports the
hypothesis of a high atmospheric O2 content during the
Carboniferous (300 million years ago), a time when insect gigantism was
widespread.
