Challenger 150 is a global cooperative devoted to delivering the science we need to sustainably manage the deep ocean.

At its heart is the development of deep-ocean expertise, particularly in economically developing nations, in order to achieve a global generation of stewards working together to maintain the integrity of deep-ocean ecosystems. Furthermore, through supporting the development of new technologies and the expansion of observations, Challenger 150 aims to advance understanding of the diversity, distribution, function and services provided by deep-ocean biota; and to use this new knowledge to educate, inspire, and promote better management and sustainable use of the deep ocean.
