Mg/Ca¶
Functions for converting between foraminiferal Mg/Ca and environmental parameters.
Exponential¶
The ‘classic’ exponential function, where Mg/Ca depends only on temperature, following:
\[Mg/Ca_{foram} = A\ e^{Temp\ B}\]
Functions¶
- Converter:
foramgeochem.mgca.exponential
- Transfer functions:
exp_mgca_2_temp()
exp_temp_2_mgca()
Holland et al (sub.)¶
The multi-factor formulation of Holland et al (sub.), which accounts for the influence of Temperature, Mg/CaSW, [Ca]SW and a species-specific carbon-system parameter (carb, i.e. DICSW, [CO3]SW or pH).
\[Mg/Ca_{foram} = Mg/Ca_{SW}\ ^A\ DIC_{SW}\ ^B\ e^{(C\ [Ca]_{SW} + D T + E)}\]
