Almost a Fifth of Earth’s Ocean Floor has Been Mapped

We have mapped 1/5 of the Earth’s ocean floor. Once could look at that as a startling accomplishment, or a wonderful opportunity to reaffirm how little we know about our own planet, or both. As Terence McKenna said, the bigger our sphere of knowledge gets, the larger the surface area of the unknown becomes. Here’s more from Engadget:

Us humans know more about the surface of the Moon than we do Earth’s oceans, but there’s progress on closing that gap. The Seabed 3030 Project reports (via BBC News) that scientists have mapped 19 percent of ocean floors to contemporary standards, or a huge leap over the six percent from Seabed’s launch in 2017. A significant portion comes from nearly 5.6 million square miles of depth data collected in project partner GEBCO’s grid in 2019. That’s roughly twice the size of Australia, Seabed 2030 said.
