Description
Equilibrations_Log_v2.2.csv: Summary of preparatory line and mass spectrometer data for equilibrations. Columns titles describe the following: samplename: full sample name shortname: short name g2bkgnd: preparatory line background pressure O2_initial_pressure_warm_predicted: initial O2 pressure, estimated for room temperature. CO2_initial_pressure_predicted: initial CO2 pressure, estimated for room temperature. equil_starting_pressure: pressure at beginning of equilibration O2_CO2_ratio: estimate of O2 to CO2 ratio. Note this value differs subtly from beta, which is calculated from mass spectrometer delta values O2_final_transfer_residual: residual pressure for transfer of O2 to manifold CO2_final_transfer_residual: residual pressure for transfer of CO2 to breakseal equil_duration: equilibration duration H2_O2_cleanse: flag if preparatory line was “cleaned” with H2 and O2 sampletype: flag for sample type O2in d17O vsmow: initial 17O of O2 O2in d18O vsmow: initial 18O of O2 O2in D17O vsmow: initial ∆17O of O2 CO2in d13C vpdb: initial 13C of CO2 CO2in d18O vsmow: initial 18O of CO2 CO2f d13C vpdb: final 13C of CO2 CO2f d13C std: standard deviation of final 13C of CO2 CO2f d18O vsmow: final 18O of CO2 CO2f d18O std: standard deviation of final 18O of CO2 O2f d17O vsmow: final 17O of O2 O2f d17O std: standard deviation of final 17O of O2 O2f d18O vsmow: final 18O of O2 O2f d18O std: standard deviation of final 18O of O2 O2f D17O vsmow: final ∆17O of O2 O2f D17O stderr: standard error of final ∆17O of O2 flag: flag for erroneous data carb17O_DD47_samples: Comparison of ∆47 calculated with the 17O correction parameters of Brand et al., (2010) (D47_Brand), Brand parameters as modified by Daëron et al., (2016) (D47_17OxsZero) and measured ∆17O of reference frame materials (D47_17OxsRG) for 2006 carbonates measured in a recent reference frame. carb17O_DD47_ETH: As in carb17O_DD47_samples, for only ETH standard data. The additional effect of carbonate ∆17O is reflected in D47_17OxsAll. 17Ocarb_ChemGeo.R: R script for all manuscript calculations and figures using the 3 files described above.
