Objectives: The objectives of Site ENT-04A are to drill through the seaward-most OOST to:

1. Sample fluids along the OOST

2. Sample the older part of the accretionary prism

3. Determine the fluid flow paths and chemical gradients

4. Determine the spatial distribution and temporal progression of deformation
