Imagine you could take away the ocean to be able to travel across the three quarters of our planet that are covered by the seas! What would these land forms tell us about our planet, its history, and the geodynamic forces that shape it? Let us embark on an imaginary sightseeing tour, with the help of visualizations that originated right out of cutting-edge ocean science. We will visit coastlines that tell us about the ocean basins beyond the horizon, and discover how robotics and computer graphics revolutionize modern seafloor research.
