Pacific Ring of Fire Expedition. This cross-section of NW Rota 1 shows the distribution of particles suspended in the waters around the volcano, as measured by an optical turbidity sensor mounted on a CTD package ("tow-yo" path shown by black saw-tooth line). The thin plumes above the volcano originate from Brimstone Pit at the summit.
