Ocean currents go global. Modeled surface currents from the E.U. Copernicus Marine Service now animate across the map worldwide, not just in US waters. Wind and wave animations have been retuned for a smoother, more realistic look. The map legend is now a simple tile grid, and Voice Control can now select search results and open every section.
