Figure F16. Summary trends at Site 1129 in (A) salinity, (B) Cl^-, (C) Na⁺, (D) K⁺, and (E) Na⁺/Cl^-. Although the ion concentration trends show a diffusive profile, the Na⁺/Cl^- ratio shows a maximum between 90 and 120 mbsf. Note the absence of gradients in the upper 40.3 mbsf, which indicates the advection of fluids through the sediments.
