In Fall 2025 the Hawaiʻi Abyssal Nodules and Associated Ecosystems Expedition, led by USGS scientists, will investigate the geology, minerals, and environmental setting of the deep seabed offshore Moku o Keawe (Hawaiʻi Island) in the U.S. Exclusive Economic Zone. This work is part of ongoing collaborative efforts with BOEM and NOAA.
