"In a study published today in Science Advances, researchers from the Ocean Discovery League reveal that only a minuscule fraction of the deep seafloor has been imaged. Despite covering 66% of Earth's surface, the deep ocean remains largely unexplored.
The study, "How Little We've Seen: A Visual Coverage Estimate of the Deep Seafloor," is the first to document that, in decades of deep-sea exploration, humans have observed less than 0.001% of the deep seafloor. This total area is roughly the size of Rhode Island or one-tenth the size of Belgium.

The deep ocean, defined as being deeper than 200 meters, sustains diverse ecosystems and provides essential services, including oxygen production, climate regulation, and crucial pharmaceutical discoveries, and plays a critical role in maintaining the health of our planet."
