Two seamounts from the Kim-Wessel Seamount Catalogue before and after being centered (20 Eotvos contours). Light blue colored points indicate the original location of the seamounts. Red points are the new centers chosen based on the maximum vertical gravity gradient (VGG) value. Credit: Earth and Space Science (2023). DOI: 10.1029/2022EA002331
