HADES: HADal Ecosystem Studies

The Hadal Ecosystems Studies (HADES) Program is a collaborative program aimed to pursue the foremost questions in trench and hadal ecosystem science, determining the composition and distribution of hadal species, the role of pressure, food supply, physiology, depth, and seafloor topography on deep-ocean communities and the evolution of trench life. These factors will be examined using the world's first full-ocean depth hybrid remotely operated vehicle (HROV Nereus) in conjunction with full-ocean depth imaging landers (Hadal-Lander). Read more...
