Please refer to the notebooks themselves and to the methodology section of the paper for understanding what they do.

There are three directories of netcdf4 files:

passive_margin_distance_grids
sediment_thickness_grids
sedimentation_rate_grids


"passive_margin_distance_grids" contains global grids of the mean distances to passive margins for any given parcel of ocean during its lifetime, from 200Ma to the present. Units are in km.

"sediment_thickness_grids" contains global grids of the compacted predicted sediment thickness through time, from 200 Ma to present. Units are in m.

"sedimentation_rate_grids" contains global grids of predicted sedimentation rates through time, from 200 Ma to preszent.  Units are in m/ka.

Please refer to the paper above for a description on how these grids were constructed.

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