A seafloor observatory at an active underwater volcano
NeMO studies the dynamic interactions between submarine volcanic activity and seafloor hotsprings at an observatory, Axial seamount. A volcanic eruption occured at Axial in January 1998, destroying some hydrothermal vent sites and creating new ones. Since then NeMO scientists have been assessing the impact of the eruption and documenting the on-going changes in Axial's summit caldera.
