This directory contains data files that are supplements to this paper:
 
Dutkiewicz, A. & Müller, R.D., 2021, The carbonate compensation depth in the South Atlantic Ocean since the Late Cretaceous. Geology.

The following folders contain input files for the backtracking of drill sites using pyBacktrack software (Müller, R. D., Cannon, J., Williams, S., and Dutkiewicz, A., 2018a, PyBacktrack: a tool for reconstructing paleobathymetry on oceanic and continental crust: Geochemistry, Geophysics, Geosystems, v. 19, p. 1898–1909, https://doi.org/10.1029/2017GC007313:

backtracked_site_data_with_SL_and_dynatopo_M7_correction
backtracked_site_data_with_SL_correction
backtracked_site_data_without_SL_and_dynatopo_correction

Each file within these folders corresponds to a single DSDP or an ODP drill site and contains data on depth, paleowaterdepth, dry bulk density, decompacted linear sedimentation rate (DSLR), carbonate content, and carbonate accumulation rate (CAR)


The following folders contain pyBacktrack output files to be used with GMT Regress software (Wessel, P., Luis, J., Uieda, L., Scharroo, R., Wobbe, F., Smith, W., and Tian, D., 2019, The Generic Mapping Tools version 6: Geochemistry, Geophysics, Geosystems, v. 20, p. 5556-5564, https://doi.org/10.1029/2019GC008515)to determine the CCD:

backtracked_data_in_1my_intervals_Walvis_Ridge_Rio_Grande_Rise_band2_in_1my_intervals_SL_and_dynamic_topo_M7_correction
backtracked_data_in_1my_intervals_with_SL_and_dynatopo_M7_correction
backtracked_data_in_1my_intervals_with_SL_correction
backtracked_data_in_1my_intervals_without_correction

Each file within these folders corresponds to a 1 my-moving time window centered on a particular age at 1 my intervals from 74 Ma to 0 Ma. Each file contains carbonate accumulation rate (CAR), paleowater depth, and name of drill site for a particular time.

The Excel file contains age, CCD depth and uncertainty for the average South Atlantic CCD as well as the CCD for the Walvis ridge/Rio Grande Rose region (see region outlined in Fig. 1) as shown in Fig. 3b.
