Objective:
|
Site CAS-04B is the reference site for the transect. It is located in the Cascadia abyssal plain, ~3 km west of the deformation front. It is similar to Site 888 of ODP Leg 146.
Primary targets are determining the pore water chemistry profile and sediment physical properties from core and logging data.
