Methane volcanic emission

The formation or release of methane from clathrate hydrates can have a profound impact on the isotopic value of surface ocean HCO3 . As outlined above, methane formation impacts the value of Aq. The rapid oxidation of methane released from sediment reservoirs influences atmospheric pC02 in a manner similar to volcanic emissions, except that the 5 C value of CO2 converted to methane is much lower than the typical 5 C value of volcanic or metamorphic CO2. Intuitively, the 5 C value of the surface ocean HCO3 will be lowered by the release of sediment methane. A more formal... [Pg.650]
