Plate tectonic cycling constrains the bulk silicate Earth hydrogen isotope composition [Dataset]

Description

This dataset contains the inputs and results of the Monte Carlo ensemble of models. Files: inputs.dat contains the sampled inputs for all models. ensemble.dat contains results for the successful models. Model IDs are shared between the two files, so each successful model can be matched to its inputs. inputs.dat columns: Column 1: Model ID Column 2: Present-day net regassing flux, F_R(0) (10^11 kg H2O/yr) Column 3: Initial (4.5 Ga) seawater δD (‰) Column 4: Initial (4.5 Ga) mantle water inventory (ocean masses) Column 5: Fractionation factor for mantle degassing, 10^3 ln f_D (‰) Column 6: Fractionation factor for slab dehydration, 10^3 ln f_DH (‰) Column 7: Fractionation factor for seafloor alteration relative to seawater, 10^3 ln f_AO^SW (‰) Column 8: Hadean tectonics option (0 = sluggish, 1 = rapid) Column 9: Hadean ridge length option (0 = constant, 1 = 10 times the present-day value during the Hadean); applies only when column 8 = 1 ensemble.dat columns: Column 1: Model ID Column 2: Present-day surface water inventory (ocean masses) Column 3: Present-day mantle water inventory (ocean masses) Column 4: Present-day seawater δD (‰) Column 5: Seawater δD at 3.8 Ga (‰) Column 6: Present-day mantle δD (‰) Column 7: Present-day continental crust δD (‰) Column 8: Present-day oceanic crust δD (‰) Column 9: Maximum deviation of sea level from its present-day level during 0–2 Ga (km) Column 10: Initial (4.5 Ga) mantle δD (‰) Column 11: Initial (4.5 Ga) surface water inventory (ocean masses) Column 12: Bulk silicate Earth δD (‰)
