I have a few question which is I have a gridded bathymetry data contains xyz (long, lat and depth). How can I calculate the gradient for every depth points from east to west and north to south. Does the ArcGIS can run this or do I have to calculate manually (but there's hundred thousand points!), can I use excel. But how, please I'm stuck.

Thank you guys!:D
