Equipment Used
|
|
|
Purpose
|
Study crustal structure and faults in the Aluetians.
|
|
|
Information to be Derived
|
Image the velocity structure of the entire crust and uppermost
mantle, including the subducting plate beneath the forearc, the forearc
basement, the backarc crust, and the arc edifice itself. Reflection and
refraction data from the whole crust and Moho on both arc-crossing
profiles.

|
|
Summary
|
12 ocean-bottom hydrophones and 7 ocean-bottom seismometers were
deployed along five transects across the Aleutian arc and backarc. Two
primary transects across the arc were acquired: one through Seguam Pass,
where the arc is intraoceanic, and one through Unimak Pass, where it is
continental.
