Abstract:
Mid-Miocene (16.6 – 12.8 Ma) sea surface ocean temperatures and sea surface productivity are obtained from the sediment record of Integrated Ocean Discovery Program (IODP) Expedition 307, Site U1318 drilled in the Porcupine Basin, north east Atlantic at a water depth of ~ 400m.
Seawater temperatures were obtained using both the TEX86 and Uk37 paleothermometers, which document the Miocene Climatic Optimum and a series of cooling events, some correspondent to the Miocene Mi-2, Mi-3 and Mi-4 events. Cooling events are also documented by changes in the dinoflagellate cyst assemblages. Sea surface productivity was reconstructed by means of dinoflagellate cysts, employing the ratio between Protoperidinioid and Gonyalulacoid (P/G) specimens in the assemblages.
