Bell Team Identifies 10,000 Deep-Seafloor Targets as Just 0.001% Has Been Visually Observed

Summary
An April 2026 Science Advances paper from Katy Croff Bell’s Ocean Discovery League mapped 10,000 priority deep-seafloor sites to guide future exploration toward the most representative biological and geological sampling.
The targets were selected algorithmically to balance geography, depth, ocean conditions and discovery potential, giving funders and research groups a roadmap for where each new dive could add the most knowledge.
That push follows Bell’s 2025 finding that humans have visually observed only 0.001% of the deep seafloor—about 3,823 square kilometers—despite 43,681 dives logged since 1958.
The existing record is heavily skewed: 97% of recorded dives came from five countries, mostly inside their coastal economic zones, while much of the central Pacific, Indian Ocean, deep Atlantic and polar oceans remains barely seen.
The gap matters as deep-sea mining and other industrial activity accelerate, leaving policymakers to weigh extraction, conservation and climate decisions with direct observations from only a tiny fraction of Earth’s largest ecosystem.
The deep sea is less explored than Mars, so why are we rushing to mine it before we understand it?
As battery tech evolves past deep-sea metals, is the ocean mining boom already headed for a bust?
Can science map our planet's final frontier before commercial mining begins to erase it?
Mapping 10,000 Deep-Sea Targets: The Global Initiative to Unveil and Protect Earth’s Last Ocean Frontier
Overview
In June 2026, the Ocean Discovery League (ODL) launched the Global Deep Sea Exploration Goals initiative to transform our understanding of the planet’s deepest environments. By identifying 10,000 specific target locations across the deep seafloor, ODL aims to create the first globally representative visual record of the deep ocean. This record is essential for making informed decisions about marine biodiversity, climate patterns, and sustainable resource management. The initiative uses an innovative methodology that overcomes historical limitations and actively corrects for long-standing observational biases, ensuring a more accurate and comprehensive view of the deep ocean.
