Volume equivalent layer thickness (VELT) grids are computed from seamount topography in the Pacific plate. We use SRTM15+V2.0 global bathymetric grid for seafloor topography. We first apply a white-Tophat filter to the bathymetry data to isolate short-spatial-wavelength seamount topography above the long-wavelength seafloor. Subsequently, we apply Gaussian Process regression to determine seamount structure above the seafloor in order to extrapolate structure beneath the sediment (GlobSed V3) to the basaltic basement (i.e., the top of the oceanic crust). Finally, we map the spatial distribution of seamount volume on the Pacific plate by calculating a volcanic equivalent layer thickness (VELT) using a moving window of 300 km × 300 km. The VELT grids have a grid spacing of 37 km x 37 km and are provided in GeoTIFF format in a cylindrical equal area projection with the following PROJ string: +proj=cea +lon_0=180 +lat_ts=30 +x_0=0 +y_0=0 +ellps=WGS84 +units=m +no_defs VELT_above_seafloor.tif is the grid for VELT above the top of the sediments. VELT_above_basement.tif is the grid for VELT above the top of the basaltic basement.
