This map shows what the seafloor looks like in the area we have been exploring.
The map was compiled using a variety of different data: single-beam echo-sounding
data, multibeam sonar data, and satellite gravity data. The shallow (red colored)
topography on the eastern (right) side of the map is closest to the Galapagos
hotspot, which forms the volcanic islands in the Galapagos Archipelago. The
Galapagos Rift is the narrow band of pink and red that extends to the west.
You can see that the rift gets deeper and look less like a straight lines
toward the west. In this area, the mid-ocean ridge has a rift valley, rather
than a crest or dome shape. The red arrow points to the area on the Galapagos
Rift that we will be surveying and the general area of the next two slides.
