Despite covering over 70% of the Earth's surface, the deep ocean remains largely unexplored.
While approximately 26% of the global seafloor has been mapped using sonar technology, only about 0.001% of the deep ocean floor has been visually explored by humans or cameras.
This means the vast majority of the ocean’s depths remain unseen, especially areas below 200 meters where sunlight doesn’t reach.
This extremely low figure—0.001%—is backed by credible sources like the Smithsonian, Live Science, and NPR.
The main reasons for such limited exploration include the extreme pressure, darkness, and technical challenges of reaching the deep sea. Most of what we know comes from remote sensing and mapping, not actual footage or human presence.
In short, the ocean’s deep floor is one of the last frontiers on Earth, with over 99.999% still waiting to be visually discovered.
