Oceanic spreading rates dataset: oceanic spreading rates and mid-ocean ridge lengths for the last 140 million years

The oceanic spreading rates dataset consists of a grid data file illustrating the age-area distribution of oceanic lithosphere, mid-ocean ridge lengths, crustal production, and seafloor spreading rates from the Early Cretaceous (140 million years ago) to the present.
The oceanic spreading rates dataset and supporting documentation is available via the EarthByte website. The dataset includes  images, grid data files and associated user documentation (readme files, related papers, supplementary materials and tables). Images are available in .JPEG format. Grid data is available for download as a Gzipped Tar File (.tgz; TAR.GZ). For further information please refer to the associated publication and the EarthByte.org website.
