Ocean discovery league launches international technique to double deep seafloor observations

New initiative identifies 10,000 goal places to create the primary consultant visible document of the deep sea.

(Saunderstown, RI — April 1, 2026) Ocean Discovery League (ODL) pronounces the launch of the Global Deep Sea Exploration Goals, an bold worldwide effort to visually discover 10,000 strategically chosen places throughout the deep seafloor. When accomplished, this initiative will almost double the variety of distinctive seafloor places ever visually noticed and produce the primary globally consultant visible dataset of the deep ocean ground. 

These observations will unlock new discoveries about biodiversity, ecosystem operate, and environmental change, serving to scientists, policymakers, and the general public higher perceive the most important and least explored ecosystem on Earth.

The methodology behind this technique was printed immediately in a Science Advances article titled “The Global Deep Sea Exploration Goals: A Representative Approach to Visually Observing the Deep Seafloor.” The paper describes how the goal places have been chosen utilizing current international datasets of key seafloor traits and descriptions the influence that observing these places might have on attaining a consultant image of deep seafloor environmental variety.

The initiative builds immediately on ODL’s landmark 2025 examine, “How Little We’ve Seen: A Visual Coverage Estimate of the Deep Seafloor,” which revealed that solely 0.001% of the deep seafloor has been visually noticed regardless of masking greater than half of the planet’s floor. 

“More than 99.999% of the deep seafloor has never been seen,” stated Dr. Katy Croff Bell, President of Ocean Discovery League, National Geographic Explorer, and senior creator of the examine. “The Global Deep Sea Exploration Goals provide the first practical roadmap to change that. By coordinating exploration efforts across the global community and focusing on locations that represent the true diversity of the seafloor, we can dramatically accelerate discovery while building a more inclusive and collaborative future for deep-sea science.”

Visual observations are one of the crucial vital non-invasive instruments out there to scientists, permitting researchers to doc marine life conduct, assess biodiversity, present context for collected samples, and characterize geological environments.

To assist the initiative, ODL has launched an open-access interactive platform that enables researchers, expedition planners, and the general public to discover the ten,000 targets and observe progress as observations are accomplished. 

“By correcting for long-standing observational biases, such as disproportionate exploration near wealthy coastal nations or specific geological features, the approach provides a roadmap for a more representative, geographically balanced observation of the deep seafloor,” stated lead creator Dr. Kristen Johannes.

A rising worldwide coalition of organizations has already dedicated to supporting the Global Deep Sea Exploration Goals, together with the National Geographic Society, Seabed 2030, OceanX, Schmidt Ocean Institute, Challenger 150, SpeSeas, LAMAVE, Marmoris, Oceanswell, and the Deep Ocean Observing Strategy (DOOS). These collaborators symbolize a broad alliance of scientific establishments, expedition packages, and international ocean initiatives working to coordinate exploration, mapping, biodiversity discovery, and ocean stewardship.

The initiative is designed to combine with ongoing international ocean science packages, together with seafloor mapping and biodiversity discovery, enabling expeditions worldwide to contribute observations alongside their current analysis targets. Because many observations will be integrated into ongoing cruises or performed with comparatively low-cost imaging methods, the Global Deep Sea Exploration Goals will be achieved via a distributed community of expeditions over the following one to 20 years.

ODL invitations analysis establishments, exploration packages, governments, philanthropic and private-sector collaborators to take part by incorporating these targets into upcoming expeditions, contributing imagery and knowledge, and supporting the growth of deep-sea exploration capability worldwide.

“Understanding the deep ocean is essential for informed decisions about biodiversity, climate, and the sustainable management of marine resources,” Bell added. “With the Global Deep Sea Exploration Goals, we now have a clear path toward seeing and understanding the deep ocean for the first time.”

The growth of the Global Deep Sea Exploration Goals was supported by the National Geographic and Rolex Perpetual Planet Expeditions program, Dalio Philanthropies, Lyda Hill Philanthropies, and the Cabot Family Charitable Trust and produced in collaboration with the University of Nebraska, Lincoln.

About Ocean Discovery League

Founded by deep-sea explorer Dr. Katy Croff Bell, Ocean Discovery League’s mission is to speed up deep-ocean exploration by creating accessible methods to broaden the neighborhood of those that discover and perceive the deep sea. ODL is creating a strategic method to develop the world of the seafloor that’s explored, mapped, and characterised whereas decreasing bills by creating lower-cost, easier-to-use instruments, know-how, and coaching. These actions, mixed with a extra focused method to deciding on exploration places, will develop deep-sea exploration to a broader neighborhood of researchers and explorers.
