Expedition to search for hydrothermal activity in the NE Lau region by conducting water-column plume surveys. In conjunction with the water column work, expedition will also be doing bathymetric mapping of the seafloor using the shipboard EM300 system in areas where high resolution maps do not exist. The primary targets are the NE Lau Spreading Center (NELSC) , the Mangatolo Triple Junction (MTJ, also called the Kings Triple Junction), and the large caldera named Volcano O (Caldera on map).
