Raw data, model outputs and plotting scripts resulting from NERC Grant NE/L011050/2: Rethinking carbonate diagenesis: clues to past carbon cycling from an overlooked carbon sink

Supplemental files (plotting scripts, tables) in support of Greene et al., 2019. Early Cenozoic Decoupling of Climate and Carbonate Compensation Depth Trends. PP2019.Greeneetal.SupplementaryTables.xlsx Tables S1-S3. Raw data for CCD time-slice reconstruction for NP8, NP10-11, and NP12-13, respectively. Raw data for each CCD time-slice reconstruction (program, site number, current and paleo- latitude/longitude, underlying basement age, current water depth, sediment cover, reconstructed paleodepth (see Methods), wt% CaCO3 mean, and individual wt% CaCO3 measurements. Tables S4-S18. Model output: time series of pCO2 and Ca2+ weathering flux for each ensemble #1 experiment. Tables S19-S22. Final year model output for each experiment in each ensembles 1-4. Final year model output for each experiment ensembles 1-4 (outgassing rate modification factor relative to x3 pre-industrial pCO2, pCO2, mean ocean [DIC], mean ocean [ALK], POC export, Ca2+ weathering flux, mean ocean temperature, mean land surface air temperature, overturning stream function min/max, and final year CSH and CCD (following Goodwin and Ridgwell [2010]). For ensembles 2-4 bolded columns indicate model variables roughly fixed across all experiments within the ensemble. PP2019_Greeneetal_Subsidence.m Matlab script for calculating paleodepth from current water depth and seafloor age. This script plots a subsidence curve for a single location and displays the paleodepth for that location at a user-specified point in the past using the subsidence equations from Cramer et al., 2009 'Ocean overturning since the Late Cretaceous: Inferences from a new benthic foraminiferal isotope compliation', Paleoceanography 24(4), PA4216 with a simplified sediment unloading term. PP2019_Greeneetal_plot_CCDcontour.m Matlab script for contouring depth/wt% carbonate data into contoured CCD snapshot.
