Unmasking Oxygen: The Isotope Enigma!

In this paper we present the first oxygen isotope record with radiometric age control of a long sediment core from the fram strait. In particular, this study deals with the. The oxygen isotope record from substage 5a in the central fram strait is represented by lighter oxygen isotope ratios than substage 5e. This probably reflects lower salinities of the. The oxygen isotope record from substage 5a in the central fram strait is represented by lighter oxygen isotope ratios than substage 5e.

Radiometric ages obtained by the u/th method in one core provide an absolute time framework for the oxygen isotope stratigraphy. The oxygen isotope record from substage 5a in the central.
