2006 Fly-throughs: Ocean Explorer Return to the
Mariana Arc
Visit the volcanoes of the 2006 Jason
dives with a virtual fly-throughs. Higher resolution bathymetry
(EM300 and SeaBat) is viewed over bathymetry derived from satellite
altimetry data. (The satellite altimetry data are courtesy of Smith
and Sandwell, 1997.) Video image size is 480x360 pixels.
Fly-throughs
at a smaller size and additional volcanoes are available on the
Ocean
Explorer 2006 Ring of Fire website.

Fly-through from south to north along the Mariana Arc. Annotated volcanoes
were dive targets on the 2006 expedition. EM300 bathymetry data (higher
resolution top layer) was collected on the 2003 and 2004 Ring of Fire
expeditions. Data are 2Xs vertically exaggerated. Data set resolution
varies: EM300 bathymetry (35 meter grid), islands (30 meter grids),
and satellite (3500 meter grid). Island data (green) are from the
Shuttle Radar Topography Mission, courtesy of USGS and NASA.

Nikko
submarine volcano, from the south and circling around the two summit
cones. The western cone is known to have an active hydrothermal system.
Depths range from 383 to 2705 meters (1256 to 8872 feet). The EM300
bathymetry data (~25 meter resolution) are overlaid on SeaBat data
(~50 meter resolution). Bathymetry data are 2.5 times vertically exaggerated.
SeaBat data are courtesy of Ko-ichi Nakamura, National Institute of
Advanced Science and Technology, Japan.
