High-resolution multibeam bathymetry collected on the 2003 and 2004 Submarine Ring of Fire expeditions, overlaid on lower-resolution satellite-derived data. The seafloor is shown as if the ocean were removed. Islands above sea level are green. The flythrough follows the 2004 cruise track, lingering at a few of the volcanoes visited on ROPOS dives during the expedition. (Note: There is no audio for this video clip.)
