A Global Data Set of Present-Day Oceanic Crustal Age and Seafloor Spreading Parameters

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. Preferred magnetic anomaly picks are also included.

Grids: Gridded datasets (netCDF-4 and netCDF-3) of present-day age, rate, asymmetry, direction, obliquity, confidence, and age misfit (in v1.1 only) 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.
