Did you know we have better maps of the Moon’s surface than of the bottom of the ocean? But now, the SWOT mission has delivered one of the most detailed maps yet of the ocean floor! More accurate maps help improve navigation and our understanding of deep-sea currents and tides. Mapping the seafloor is in addition to SWOT’s primary goal of measuring the height of nearly all water on Earth’s surface, including the ocean, lakes, reservoirs, and rivers.
