Notes: Age determinations from Shipboard Scientific Party (2004) and S. Gardin (pers. comm.). OAE = oceanic anoxic event, MCE = mid-Cenomanian event,? = undetermined. TOC = total organic carbon, S1 = free hydrocarbon (gas and oil), S2 = hydrocarbon generated through thermal cracking of nonvolatile organic matter, S3 = CO2 produced during pyrolysis of kerogen, HC = hydrocarbon, PI = productivity index, PC = pyrolized carbon, HI = hydrogen index, OI = oxygen index.
