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.
