New marine gravity anomaly map

Tuesday , 11, November 2014

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: global_grav_1min (I downloaded the grav.img.23… files)
