Hydrothermal Vents On The Seafloors Of Ocean Worlds Could Support Life

by Keith CowingJune 25, 2024June 25, 2024

We’ve all seen the surreal footage in nature documentaries showing hydrothermal vents on the frigid ocean floor—bellowing black plumes of super-hot water—and the life forms that cling to them. Now, […]

The GEBCO world map shows the known bathymetry of the global seabed in the form of a shaded relief colour map. The imagery is based on the 2022 version of the global GEBCO grid -- GEOMAR

Ocean Planet Mapping: On The Way To A Complete Seafloor Map For Our Homeworld

by Keith CowingMay 6, 2024

At least twice in the last 20 years, nuclear submarines have collided with previously unknown underwater mountains called seamounts. The reason: they were not on any nautical charts. Just last […]
