Sea surface height gradient magnitude in a yearlong 1/8° simulation using the GOLD model, courtesy of Harper Simmons, re-mapped using {sphereinterp}. The “wiggles” are currents and eddies; the rapid flickering is the tide; the small-scale “washboard” patterns are internal waves. From work in progress comparing real and modeled surface drifters by Lilly, Early, and Simmons.
