Summary of Field Work: |
Characterization of fault zone structure, crustal and sedimentary deformation and velocity structure of the lithosphere along an oceanic-continental transform margin. We will shoot ~4000 km of long-offset seismic reflection data and ~1800 km of coincident wide angle OBS data. Gravity, magnetics and bathymetry will be collected along the ship track. |
|
Summary of Facility Requirements: |
We will need a 15 km long seismic streamer and 1600 cu in airgun array. Instruments for gravity and magnetics are desired; multibeam echosounder. |
