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– timesofindia.indiatimes.com

Less than 30% of the world’s ocean floor has been mapped to modern standards, meaning scientists still have a clearer view of the Space, Moon and Mars than of the seabed that covers most of Earth.The global effort known as the Seabed 2030 project has raised mapped coverage from about 6% in 2017 to roughly 28.7% as of early 2026, according to tracking data used by the programme and NOAA. That still leaves more than two thirds of the ocean floor unmeasured in any detailed way.The gap is striking because the oceans cover about 71% of the planet’s surface.
