| The Marine Virtual Explorer is a CD or web-based activity that allows
the user to explore hydrothermal vent fields on the East Pacific Rise as
if you are inside the research submarine, Alvin. The overview movie is a
2 minute animated tour of the MARVE study area. The tour follows the ALVIN
submersible as it discovers 2 areas of hydrothermal activity. As you watch
this movie, notice the overall shape of the area. The height of the seafloor
falls into two ranges, (high on the falls, low on the floor of caldera/graben
structure). |
|
| The narrow region of the low elevation, is the actual width
of the active volcanic area; outside that area little or no volcanic activity
occurs. |
