Ocean Exploration Trust is a nonprofit organization dedicated to discovering and sharing knowledge about the ocean. Through its Nautilus Exploration Program, the organization conducts scientific exploration of the seafloor, investigating geology, biology, and archaeology aboard Exploration Vessel Nautilus. Led by Dr. Robert Ballard and the Corps of Exploration, its expeditions use remotely operated vehicles and other technology to explore underwater environments and make discoveries accessible to the public.

Nautilus Live streams exploration activities and provides expedition updates, videos, and information about ship operations, vehicles, and ocean data. The organization also shares highlights from its research and introduces the people involved in exploration. Its education and participation opportunities include science and engineering internships for students and early-career professionals, Science Communication Fellowships for educators and communicators, and an annual art and design contest for young people. Visitors can learn about current and past expeditions, explore educational resources, follow the team’s work, and sign up for newsletters.
