Figure F14. Chloride (Cl-) concentration profile showing its relationship to the position of the reflectors in the multichannel seismic data at Site 1252. A major change in the chloride gradient occurs at the top of the accreted sediments at ~120 mbsf. Other slope changes occur at 165 mbsf, which might correspond to the bottom of the GHSZ, and at 214 mbsf.
