Figure F44. Methane phase diagram with total methane concentration measured from the single degassed PCS core at Site U1326. The seafloor temperature was estimated from previous sites, the salinity profile was taken from Table T4, and methane saturation was calculated according to Xu (2002, 2004). Methane phase boundaries for five different thermal gradients are plotted, as in situ temperature measurements were extremely difficult at this site (see "In situ temperature profile"). BSR = bottom-simulating reflector.
