Stable isotope record of DSDP Hole 81-552A in the northeastern Atlantic Ocean

Oxygen and carbon isotope ratios in benthic foraminifers have been determined at 10 cm intervals through the top 59 m of DSDP Hole 552A. This provides a glacial record of remarkable resolution for the late Pliocene and Pleistocene. The major glacial event which marked the onset of Pleistocene-like g...

Description
Summary:Oxygen and carbon isotope ratios in benthic foraminifers have been determined at 10 cm intervals through the top 59 m of DSDP Hole 552A. This provides a glacial record of remarkable resolution for the late Pliocene and Pleistocene. The major glacial event which marked the onset of Pleistocene-like glacial-interglacial alternations was at about 2.4 m.y. ago. These very high-resolution data do not support the notion of significant Northern Hemisphere glaciation between 3.2 and 2.4 m.y. ago.
