Here we applied an organic geochemical proxy (TEX86) on organic matter-rich Albian-Santonian sediments, recovered from Ocean Drilling Program Leg 207 Sites 1258 and 1259 on Demerara Rise, to reconstruct sea surface temperatures (SSTs) in the western equatorial Atlantic. Preceded by a stepwise Cenomanian warming trend (~31-35°C), the onset of the Cretaceous thermal maximum coincided here with the Cenomanian-Turonian boundary event. Once established, this extreme warm climate regime, characterized by averaged tropical SSTs close to 35°C, lasted up to the Turonian-Coniacian transition. Two pronounced cooler intervals (~2-3°C) interrupt this otherwise remarkably stable record, providing the first d18O independent evidence for middle Turonian cooling that previously has been attributed to glacioeustatic sea-level lowering. Coniacian SSTs decline stepwise, reaching a minimum in the Santonian (~32-33°C), where cooling is most pronounced, presumably concomitant with the first progressive opening of a deep-water passage through the equatorial Atlantic gateway.","descriptionType":"Abstract"},{"description":"Supplement to: Forster, Astrid; Schouten, Stefan; Baas, Marianne; Sinninghe Damsté, Jaap S (2007): Mid-Cretaceous (Albian-Santonian) sea surface temperature record of the tropical Atlantic Ocean.
