Figure 4 (continued). I. Core 164-995B-7P released 2330 mL of gas (~2250 mL of CH₄) at 0ºC over 155 min. The core was not removed from the ice bath after reaching atmospheric pressure. J. Core 164-995B-10P released 680 mL of gas (~555 mL of CH₄) at 0ºC over 144 min, and 980 mL of gas (~855 mL of CH₄) at less than ~15ºC over a total time of 877 min. The rise in pressure at 1105 mL reflects long warming of this core after relatively rapid gas release in the early stages of the experiment. K. Core 164-996A-7P released 5030 mL of gas (~4930 mL of CH₄) at 0ºC over 701 min, and 5415 mL of gas (~5315 mL of CH₄) at less than ~15ºC over a total time of 852 min. This core should have had CH₄ hydrate even after equilibration of gas with borehole water in the outer chamber. L. Core 164-996D-7P released 7810 mL of gas (~7680 mL of CH₄) at 0ºC over 974 min, and 8100 mL of gas (~7970 mL of CH₄) at less than ~15ºC over a total time of 1136 min. This core should have had CH₄ hydrate even after equilibration of gas with borehole water in the outer chamber.
