Ocean Discovery League’s (ODL) flagship capacity-building and mentorship program, Accessing the Deep (ATD), is transforming how early-career individuals gain meaningful entry into deep-sea exploration. In 2026, ATD will enter its third year, continuing to counter the inefficient and expensive deep-ocean research practices that have long limited our ability to explore at scale.

​

This global gap in access has led to biased research priorities, restricted scientific discovery, slowed development of sustainable ocean-based economies, and kept many communities from fully recognizing the deep ocean’s value. ATD is designed to broaden participation and ensure that a wider diversity of voices helps shape the future of deep-sea exploration.

​

Participants receive comprehensive online training in technical and oceanographic knowledge from leading international deep-sea science experts, with a focus on low-cost, accessible approaches for exploring waters deeper than 200 m. The program also supports participants in crafting research proposals that integrate affordable tools and locally relevant exploration strategies.

​

After completing the training, participants are paired with deep-sea or regional mentors who guide them in developing tailored research proposals, ensuring they are prepared to make substantial, place-based contributions to the field.

​

The deep sea covers two-thirds of our planet, yet more than 99% remains unexplored. ATD is building the community that will help change that, together.
