temp_d18O()
calculates carbonate growth temperature
from oxygen isotope data.
Arguments
- d18O_c_VSMOW
Carbonate d18O value expressed on the VSMOW scale (‰).
- d18O_H2O_VSMOW
Water d18O value expressed on the VSMOW scale (‰).

a18_c_H2O()
.
Note
Use to_VSMOW()
and to_VPDB()
to convert between the
VSMOW and VPDB scales.
