As the view transitions to select regions of interest, SWOT's high-resolution SSHA measurements unveil detail impossible with previous satellite technology. The visualization clearly distinguishes ocean surface waves, internal solitary waves, and submesoscale eddies—critical features for understanding ocean dynamics and energy transfer. The color gradient ranges from dark blue (representing lower surface heights) to white (indicating higher surface heights), allowing viewers to immediately grasp the three-dimensional nature of these ocean phenomena.",
