Less than 30% of Earth’s ocean floor has been mapped while scientists still have clearer high-resolution data of Mars than most of the seabed covering our own planet

Despite the vastness of Earth's oceans, only about thirty percent of the seafloor is charted to modern specifications, revealing a stark difference with Mars, whose surface boasts complete mapping. The Seabed 2030 initiative has dramatically improved ocean coverage from six to nearly twenty-nine percent. This meticulous mapping relies on ships and sonar, a time-intensive endeavor crucial for effective tsunami predictions and maintaining submarine cables.
