Description

Datasets of present-day oceanic crustal age and seafloor spreading parameters from Seton et al. (2020).

This dataset contains:

  • Animations: animations of the present-day age grid and seafloor spreading parameters in both low and high resolution
  • Feature Data: GPlates compatible files (*.gpml and *.rot) consistent with and used to create this dataset. 
  • Grids: Gridded datasets (netCDF-4 and netCDF-3) of present-day age, rate, asymmetry, direction, obliquity, in 6 minute resolution. Age grids are also provided in 1 and 2 minute resolution as netCDFs, and as 6 minute xyz files.
  • Images: Images of the present-day age grid and seafloor spreading parameters
  • Workflows: the latest workflow to create the present-day age grid can be found on GitHub: https://github.com/EarthByte/presentday-agegridding 

These files can also be downloaded from the EarthByte website here, and the global plate motion model can be found online here.
