* = –0.9 m tidal height when mudline Core 339-U1386-1H was taken. In situ temperatures were determined using TP-Fit software by Martin Heesemann. Thermal resistance was calculated from thermal conductivity data (see “Physical properties”) corrected for in situ conditions (see “Downhole measurements” in the “Methods” chapter [Expedition 339 Scientists, 2013b]).
