History of Plio-Pleistocene climate in the northeastern Atlantic, Deep Sea Drilling Project Hole 552A.

Abstract

Lithologic, faunal, isotopic, and paleomagnetic analyses indicate that the section represents the most complete deep sea record of climatic evolution hitherto recovered at high latitudes in the N Hemisphere. In the upper part of the section, the whole of the standard oxygen isotope record of the past million years is well preserved. The onset of ice-rafting and glacial-interglacial alternations occurs at about 2.4 Myr ago. -Authors
