Surveying Pele's Pit Crater on Lōʻihi Seamount

Lōʻihi Seamount is an underwater volcano 35km off the Big Island of Hawai'i, but its hydrothermal venting makes it a possible analog to what researchers think may be found in ocean worlds elsewhere in the solar system. As the SUBSEA team aboard Nautilus explored Pele's Pit crater near Lōʻihi's summit, bright yellow expanses stretched over lava rock--likely iron oxide deposits from active venting or iron-eating microbes.
