Modification of the oxygen-isotope record in deep-sea cores by Pleistocene dissolution cycles

Auteur :
EREZ, J.

Description :
The glacial-interglacial amplitude (GIA) of oxygen-isotope curves in sediment cores from the Atlantic Ocean is much higher than the amplitude in the Pacific. This difference is explained by nonsynchronous CaCO dissolution cycles during the Upper Pleistocene that amplify the GIA in the Atlantic and reduce the GIA in the Pacific. Efforts to assess palaeotemperatures in the Pleistocene using the stable isotope technique must consider the affects of dissolution.
