Summary of Field Work: |
Deployment of 10 broadband OBSs equiped with seafloor flow meters on the accretionary complex offshore central Chile in water depths of 2000-5300 m.
Acquisition of high-resolution seismic reflection data using a short multichannel streamer and GI guns. (first cruise only)
Swath bathymetry, magnetics, gravity
Gravity cores (second cruise only) |
|
Summary of Facility Requirements: |
Need adequate deck space and cranes to handle OBSs on deck. Need air compressor in yr 1 for seismic reflection. |
