This "before and after" image provides a glimpse of Okeanos Explorer’s EM302 mapping system capabilities in deep water. The top image shows what we previously knew about the seafloor terrain in the southern Mariana region from satellite altimetry data. The bottom image includes an overlay of the information provided by the ship's EM302 multibeam system. Okeanos Explorer will focus on mapping waters deeper than 2000m during the expedition, while Baruna Jaya IV will collect multibeam data down to 2000m – the maximum rating of its multibeam system.
