Depth profiles at Holes C0008A and C0008C. (Left to right) In situ temperature (black curve with red best-fit line); maximum recorded temperature during measurements (Tmax) (blue); residual temperature (black); chlorinity (red); δ
18O isotopic ratio (blue); estimated hydrate saturation (red dots from chlorinity, blue dots from δ
18O); total volume fraction estimated from Cl anomaly (black line) at Holes C0008A and C0008C. Tf (black dashed line): temperature at gas/hydrate phase boundary.
