Figure F15. Chloride (Cl-) concentration profile at Site 1244 showing the Cl- relationship to the position of the bottom-simulating reflector (BSR) at the base of the GHSZ and Reflector AC. Although the chloride anomalies in both Holes 1244B (red circles) and 1244E (blue squares) are limited to the depth interval ranging from 40 mbsf to the depth of the BSR, the depth of individual chloride anomalies varies from hole to hole because of the heterogeneous presence of gas hydrate and pore water sampling resolution.
