Figure F18. Comparison of the chloride (Cl-) concentration profiles in Sites 1244 (solid circles, solid line) and 888 (open squares, dashed line). Note that the data from each site trace similar background chloride profiles in the upper 50-60 m. This similarity is the basis for our preferred estimate of the gas hydrate inventory at Site 1244.
