ESA dixit:

“Having detailed knowledge of the shape of the seafloor is essential for generating nautical charts for navigation. It is also needed for exploration, fishing, coastal management and for understanding ocean currents that transport heat, nutrients and pollutants. While mapping the seafloor was traditionally carried out using sonar on ships, optical satellite data provide global, high-resolution maps that show ridges, valleys and sediments.”
