Abstract	The shallow sections of most holes drilled during Ocean Drilling Program Leg 139 contain alkenones derived from prymnesiophyte algae. The alkenones indicate a paleotemperature of the photic zone in the upper ocean during primary carbon fixation of 7°-15°C, with an average of 10.7°C. Based on laboratory hydrous pyrolyses these alkenones are altered to unknown products around 200°C and are thus useful as thermal probes. The disappearance of the alkenones occurs at various depths below seafloor in accordance with observed heat flows.
