Last month I noticed a new paper by Sandwell et al. in Science. It’s about: “New marine gravity anomaly map derived from satellite altimetry reveals tectonic structures of the ocean basins in unprecedented detail, especially in areas covered by thick sediments.”
They provided a download link to the data and I was able to easily open the data into ArcGIS. The color-coded result is shown below.
You can download the data here: ftp://topex.ucsd.edu/pub/ global_grav_1min (I downloaded the grav.img.23… files)
