This directory contains digital grids that are supplements to this paper:

Dutkiewicz, A., Müller, R.D., Cannon, J., Vaughan, S. and Zahirovic, S., 2019, Sequestration and subduction of deep-sea carbonate in the global ocean since the Early Cretaceous, Geology, https://doi.org/10.1130/G45424.1

There are two directories of netcdf4 files:

paleobathymetry_grids
carbonate_sediment_thickness_grids

The directory "paleobathymetry_grids" contains global grids of paleobathymetry in (negative) meters from 120Ma to the present in 0.1 degree resolution.  They including basement depth from applying a plate model to the age grids here:

They also include the elevation of Large Igneous Provinces through time following the method of Muller et al. (Science, 2008) and the compacted, isostatically compensated total sediment thickness taken from here:

The directory "carbonate_sediment_thickness_grids" contains global grids of modelled carbonate sediment thickness through time, from 120 Ma to present, in 0.5 degree resolution. Units are in m. There are two sets of grids.  One set is compacted, using a porosity-depth relationship for average deep sea sediments as described in:

Dutkiewicz, A., Müller, R.D., Wang, X., O’Callaghan, S., Cannon, J. and Wright, N.M., 2017. Predicting sediment thickness on vanished ocean crust since 200 Ma. Geochemistry, Geophysics, Geosystems, 18, 4586-4603.

The decompacted set of grids is uncompacted. The uncompacted grids are not useful for modelling the actual approximate sediment thickness through time, but are useful for carbonate carbon flux calculations.

Please refer to the papers above for additional details on how these grids were constructed.

The netcdf grids can be viewed using the free software Panoply, or using the Generic Mapping Tools v5.
