Notes: Salinity was analyzed in one interstitial water sample from Core 311-1329C-7P (Table T3) and extrapolated from adjacent cores in all other cases (Table T3). Temperature was calculated from sediment depth assuming a seafloor temperature of 3.3°C and a thermal gradient of 72°C/km (see "In situ temperature profile"). Pressure was calculated from sediment and water depth (946 mbsl). Methane saturation was calculated from temperature, pressure, and salinity according to Xu (2002, 2004).
