Supporting Information for "Deep-Sea Carbonate Carbon Sequestration in the Pacific Ocean since the Early Cenozoic"

This collection of files is supplementary to:

Dalvand, F., Dutkiewicz, A., Wright, N.M., Mather, B.R. and Müller, R.D., Deep-Sea Carbonate Carbon Sequestration in the Pacific Ocean since the Early Cenozoic.

The archive contains: 2 folders of data files: “Backtracked_sites” and “Regional_Cenozoic_carbonate_thickness_grids”1 excel workbook: Table_S1_model_data_summary_for_six_regions_of_the_Pacific.xlsx 1 animation: “Movie_S1_compacted_carbonate_thickness_map_of_the_pacific.mp4”

“Backtracked_sites” folder

This folder has 6 subfolders containing pyBacktrack output files, each corresponding to a single DSDP, ODP or IODP drill site from one of six regions of the Pacific. 

Files named “Site*_age_depth_waterdepth.txt” contain data on age (Ma), compacted_depth (m), compacted_thickness (m), decompacted_thickness (m),  decompacted_density (g/cm^3), water_depth (m), tectonic_subsidence (m), decompacted_depth (m), dynamic_topography (m) and lithology.

Files named “Site*_depth_age_waterdepth_dens_DLSR_carb_CAR_filter_width_1my_step_0.5my.txt” contain data on age, depth, paleowater depth, dry bulk density, decompacted linear sedimentation rate (DSLR), carbonate content, and carbonate accumulation rate (CAR).

“Regional_Cenozoic_carbonate_thickness_grids” folder

This folder has 6 subfolders, each containing NetCDF files of modeled Cenozoic carbonate thicknesses for a different region of the Pacific from 55 Ma to 0 Ma in 1 Myr intervals. The workflow for generating these grids can be found on GitHub at https://github.com/EarthByte/CarbonateSedimentThickness

"Table_S1_model_data_summary.xlsx" This workbook contains computed decompacted carbonate sediment volume, decompacted carbonate sediment thickness, carbonate carbon flux, carbonate carbon mass and carbonate compensation depth (CCD) for six regions of the Pacific spanning 55 Ma to 0 Ma in 1 Myr intervals.

"Movie_S1_compacted_carb_thick_Pacific_55-0Ma.mp4" 

This file shows the Cenozoic evolution of the carbonate sediment thickness in the Pacific from 55 Ma to 0 Ma in 1 Myr intervals.
