The deep ocean represents over 96% of the habitable space on earth, and its healthy functioning is critical for the well-being of the wider Earth system. Yet human activities in the deep ocean are accelerating rapidly, impacting this vast habitat in numerous ways.

DOSI assembles working groups of experts to focus on specific topics from climate change and deep-sea mining to fisheries and pollution. These groups work across sectors to assimilate the leading science in each topic area and advise on ecosystem-based management of resource use in the deep ocean and strategies to maintain the integrity of deep-ocean ecosystems within and beyond national jurisdiction. In this way, DOSI seeks to aid decision-making relating to deep ocean governance at the UN and other international and national processes, in part through our accessible policy briefs.
