The fourth series of the Ring of Fire Expedition was devoted to mapping the seafloor.
While ocean mapping has been essential to the success of both the science and diving objectives, it is also fundamental to the larger global understanding of our oceans. Fewer than 20% of the world’s oceans are mapped at high resolutions (100m) and even less of the deep sea has been mapped at all. Over the last two years, the mapping team has been collecting data in the deep sea (6000 m and deeper) all around the world, and the Ring of Fire Expedition was no exception. We collected bathymetry data covering the Philippine, Palau, Yap, Mariana, Izu-Bonin, Japan, Kuril-Kamchatka, and Aleutian Trenches, some of which has never been seen before!
The mapping team is led by Cassie Bongiovanni, a scientist specializing in ocean mapping and bathymetric data collection.
